Sonarr and Lidarr had the same deadlock and the same missing confirmation as Radarr, so give them the same budget and strikes

The window editor is path-first, which is exact but slow for the case that is nearly all of them.
The chips only offer whole shares; a subpath already in the window marks its share partial rather
than offering to widen it, and the path box stays the only way to express a subpath or a profile.

+
+Retrieval over Varaverk's own documentation. Ask the system a question about itself and get an
+answer grounded in its actual headers, READMEs, Manuals and conf templates — with sources.
+
+Everything here is **off by default and optional**. Varaverk works exactly as well with
+`AI_ENABLED=false` as with it true. Nothing in the ecosystem depends on this folder.
+
+| File | Role |
+|------|------|
+| `ai_index.sh` | Build / refresh the retrieval index |
+| `ai_query.sh` | Ask a question, or search the index directly |
+| `lib/chunk.js` | Split repo files into retrieval units |
+| `lib/index.js` | Embed chunks, store vectors in SQLite |
+| `lib/search.js` | Embed a query, score it, rank results |
+| `lib/cli.js` | Argument bridge the bash entry points call |
+
+---
+
+## ━━━ WHY THIS WORKS AT ALL ━━━
+
+**Because the header audit came first.**
+
+The single worst failure in naive retrieval is a chunk that contains half of one idea and half
+of another — a fixed-size window cutting mid-thought, embedding two unrelated things as one
+vector. That problem does not exist here, because every script in the repo carries the same six
+sections at exact, greppable boundaries:
+
+```
+PURPOSE → OPERATIONAL MODEL → DESIGN PRINCIPLES → OPERATIONAL SAFEGUARDS
+        → CONFIGURATION → RUNTIME MODES
+```
+
+Split on those and every chunk is a coherent unit by construction. No token windows, no overlap
+heuristics, no tuning.
+
+**And because the headers say *why*.** A model can read `mover_stop.sh` and describe what it
+does. It cannot look at that code and know the cache writers are lockless *on purpose*, or that
+`removeCompletedDownloads` being true on both arrs is intentional. Those live in
+`DESIGN PRINCIPLES` and `OPERATIONAL SAFEGUARDS`, which is precisely what makes this index worth
+more than an equivalent pile of source.
+
+---
+
+## ━━━ SECTION ROUTING ━━━
+
+Every chunk stores its section name as its own column, so a question's *shape* can steer
+retrieval before similarity is even considered:
+
+| Question shape | Steered toward |
+|----------------|----------------|
+| "what stops X and Y overlapping" | `OPERATIONAL SAFEGUARDS` |
+| "which variable controls X" | `CONFIGURATION` |
+| "does this take --dry-run" | `RUNTIME MODES` |
+| "why is it built this way" | `DESIGN PRINCIPLES` |
+| "how does X work" | `OPERATIONAL MODEL` |
+
+Applied as a **score boost, not a filter**. Intent detection is a heuristic, and a heuristic
+must never be able to exclude the one chunk that holds the answer. `--section=NAME` forces a
+hard filter when you actually want one.
+
+The boost still has a blind spot worth knowing about: **definitional questions.** "What is
+Varaverk?" matches the `PURPOSE` intent, so every script's one-line PURPOSE gets boosted above
+the top-level prose that actually answers it — and the model correctly replies that the context
+does not define the system. The corpus is fine; `README.md` is indexed. The routing simply
+buries it. `--kind=readme` is the hard filter for that case:
+
+```bash
+bash AI/ai_query.sh --kind=readme "what is Varaverk"
+```
+
+`--kind` filters on where a chunk came from — `header`, `readme`, `manual`, `template`, `doc`, `ui` —
+and composes with `--section`. Prefer it over `--section` for "what is" and "why does this
+exist" questions, where the answer is narrative rather than a header field.
+
+---
+
+## ━━━ NAMED-PARAGRAPH SUB-CHUNKING ━━━
+
+Sections alone were not granular enough, and the failure was instructive.
+
+`rsync.sh` documents fourteen distinct safeguards in one 2.8k-character
+`OPERATIONAL SAFEGUARDS` block. Asked *"what happens if pass 1 of a merge run fails"*, the
+correct chunk scored **0.558** — below unrelated chunks from other files — because the other
+thirteen safeguards dominated the vector.
+
+The header convention writes each safeguard as a named paragraph: an unindented title, an
+indented body. Splitting on those titles took the same query to **0.718** and first place.
+
+```
+Merge-Run Delete Interlock            ← its own chunk
+  --delete is applied only when pass 1 completed...
+```
+
+The parent section name is carried onto every sub-chunk, so routing still works. The title
+detection requires the *next* line to be indented — without that check, any wrapped prose line
+became a spurious boundary mid-sentence.
+
+---
+
+## ━━━ WHAT IS INDEXED ━━━
+
+Roughly 2,900 chunks across ~180 files:
+
+| Kind | Source |
+|------|--------|
+| `header` | Script headers — bash and PHP, sections and named paragraphs |
+| `readme` | Every `README-*.md` |
+| `manual` | Every `Manual-*.md` |
+| `template` | `Deployment/*.template` — the versioned conf schema |
+| `doc` | Top-level `README.md`, `Manual.md`, design notes |
+| `ui` | `Plugin/unraid/pages/readme/*.md` — the WebGUI's own help panels |
+
+**Script bodies are not indexed.** Headers state intent, code states mechanism; for the
+questions this answers, intent retrieves better and costs far less.
+
+---
+
+## ━━━ THE SAFETY BOUNDARY ━━━
+
+**Only `git ls-files` is ever indexed.** This is not a convenience — it is the security model.
+
+`Configurations/` and `data/` are gitignored, so every file holding a credential
+was never in the repo to begin with. The index therefore describes the full conf schema (via the
+tracked templates, which carry all the explanatory comments) while structurally **never
+containing a secret**.
+
+> Do not "improve" this into a filesystem walk. A logged secret can be rotated. A secret
+> averaged into a 768-dimension float cannot be found, let alone removed.
+
+A live conf value the model genuinely needs should arrive through a tool call at query time,
+subject to redaction — never baked into a vector at index time.
+
+---
+
+## ━━━ HOW IT IS BUILT ━━━
+
+**SQLite, no vector database.** ~2,900 chunks × 768 dims is a couple of million multiply-adds
+per query — under a millisecond. A vector DB would be a container to run, monitor, fail over and
+back up, in exchange for nothing at this scale.
+
+**Vectors are raw little-endian float32 BLOBs.** `nomic-embed-text` returns L2-normalised
+vectors, so cosine similarity is a plain dot product — no normalising, no magnitude cache. PHP
+reads the same blobs with `unpack('f*', $blob)` when the UI needs them.
+
+**Incremental on mtime.** A file whose mtime has not moved is skipped without being read. A
+no-op refresh takes about 70 ms; a full rebuild takes a few minutes.
+
+**Node for the maths, bash for everything else.** The bash entry points own configuration,
+gating, locking and logging exactly as every other Varaverk job does. Node owns only float
+vector maths and SQLite BLOBs. Same split as `api_cache_writer.sh` and its PHP.
+
+> `lib/index.js` uses `node:sqlite`, which Node still marks experimental. It is used because it
+> needs no native compilation on Unraid. If a Node upgrade ever breaks it, the index is
+> regenerable in minutes — this is a disposable artefact, not a datastore.
+
+---
+
+## ━━━ USAGE ━━━
+
+```bash
+# Build (needs AI_ENABLED=true)
+bash AI/ai_index.sh                  # incremental
+bash AI/ai_index.sh --force          # full rebuild
+bash AI/ai_index.sh --dry-run        # what would be indexed; contacts nothing
+bash AI/ai_index.sh --status         # size, counts, last build
+
+# Ask
+bash AI/ai_query.sh "what stops rsync and the mover running at once"
+bash AI/ai_query.sh --search "why are the cache writers lockless"
+bash AI/ai_query.sh --section=CONFIGURATION "which variable sets the mover grace period"
+bash AI/ai_query.sh --kind=readme "what is Varaverk"          # definitional / narrative
+bash AI/ai_query.sh --json "..."     # for other scripts
+```
+
+**`--search` is the trustworthy mode.** It returns verbatim repo text with nothing generated.
+When the answer matters, use it — or read the sources the generated answer cites.
+
+---
+
+## ━━━ TRUST THE SOURCES, NOT THE PROSE ━━━
+
+The generation prompt instructs the model to answer only from retrieved context and to say what
+is missing rather than fill the gap from general knowledge. That instruction matters here more
+than usual: this repo's conventions are frequently *not* the conventional ones, and a confident
+generic answer about rsync, Docker or systemd is worse than no answer.
+
+It works — and its faithfulness cut both ways on the first real test. Asked which variable
+controls the mover's grace window, the model answered `MOVER_STOP_TIMEOUT`, "defaults to 30
+seconds", citing `mover_stop.sh › CONFIGURATION`. The variable was right. The 30 was wrong — the
+real value is 300 — and the model was quoting the header verbatim. **The header was stale.**
+
+That sweep then found six stale `(default: N)` claims across the repo, all since corrected. The
+lesson is the operating principle for this whole folder:
+
+> Retrieval is exactly as accurate as the documentation it points at. When an answer looks
+> wrong, check the cited source before blaming the model — it is usually reporting a real
+> problem in the repo.
+
+---
+
+## ━━━ WHAT THIS DOES NOT DO ━━━
+
+- **It does not write conf.** `AI_CONF_WRITE_ENABLED` exists in `master.conf` and is off, with
+  an empty key whitelist. Nothing in this folder writes a setting.
+- **It does not make decisions.** No watchdog, cleanup or fallback path consults it. The
+  per-feature `AI_ASSIST_*` toggles are all false and each one is earned separately.
+- **It does not index code.** Headers and docs only.
+- **It does not sync.** The index is host-local and gitignored. Each node builds its own.
+- **It is not required.** Every script runs identically with `AI_ENABLED=false`.
+
+See `Notes_AI-Design.md` at the repo root for the wider design — host resolution across the
+Tailscale mesh, per-feature rollout tiers, and the conf-write guardrails that would have to be
+built before any of that is enabled.
+
+---
+
+## ━━━ SCHEDULING ━━━
+
+The index tracks the repo automatically, from the only moment the corpus actually changes — a
+successful pull. `git_pull_execute.sh` re-indexes behind three gates: the pull succeeded and
+changed tracked files, `AI_INDEX_ON_PULL=true`, and `AI_ENABLED=true`. It is never fatal — a
+failed index leaves the previous one in place and the pull still reports success.
+
+No cron entry and no `DAILY_MAINTENANCE_SCRIPTS` line are needed; the daily pull carries it.
+
+An incremental run on an unchanged repo is ~70 ms, so a daily entry costs effectively nothing
+and a pull that changed twelve files costs a few seconds.
+
+---
+
+## ━━━ PROFILES ━━━
+
+A profile is a contract plus a set of inputs. `Plugin/unraid/include/ai_profiles.php` is the one
+definition of both, read by the endpoint, the worker, the shared chat include and the Scheduler
+dock.
+
+| Profile | Turns | Retrieves | Notes |
+|---|---|---|---|
+| `varaverk` | 3 | yes | answers only from the index, with citations. The default. |
+| `chat` | 8 | **no** | ordinary conversation. Holds zero capabilities, deliberately. |
+| `code` | 4 | no | drafts shell for Custom Scripts; scans its own output for destructive ops |
+| `troubleshoot` | 2 | yes | reasons from evidence — an open log, or one you name. May file bug reports. |
+
+Capabilities are granted per profile — retrieval, live health, run evidence, scoped log,
+incidents, conf lookup, bug filing, code scanning. `chat` holding an empty list is a guarantee,
+not an oversight: anything added to it stops being general chat and becomes an assistant that
+sometimes invents claims about this installation.
+
+### Routing out of General Chat
+
+`chat` hands a question to whichever profile fits, decided by `vv_ai_route_from_chat()`. Ordered
+most specific first, because these overlap on purpose:
+
+| Question | Goes to | Why |
+|---|---|---|
+| "write me a script that prunes logs" | `code` | asked for something written |
+| "why did the daily orch fail" | `troubleshoot` | diagnostic phrasing **and** something here to diagnose |
+| "how did the daily orch go" | `varaverk` | about this install, but not a fault |
+| "what does arr_sync.sh do" | `varaverk` | names a script, wants documentation |
+| "why is the sky blue" | stays `chat` | diagnostic phrasing about nothing here |
+
+`code` is checked first because it is the only intent about a thing that does not exist yet, so
+nothing else can claim it — and it is anchored on the verb, which is what keeps "write me a
+script" apart from "what does this script do". Escalation adds capability, so a wrong escalation
+costs more than a missed one: anything unrecognised stays in `chat`, the profile that cannot
+invent claims about this system. The worker reverts to `chat` anyway if retrieval comes back
+empty.
+
+The answer opens with one line naming the profile that took it, because the button still shows
+the one you picked and an answer arriving under a different contract otherwise reads as the
+assistant ignoring you.
+
+Routing is asserted by `Plugin/unraid/Tools/ai_explain_check.sh` against
+`ai_explain_fixtures.txt` — every case runs through the worker's `--explain` mode, which stops
+where deterministic assembly ends and never calls the model.
+
+This used to live in five places — history depth in the endpoint, capabilities in `include/ai.php`,
+label and depth again in JavaScript, a prompt branch in the worker, and a label map on the
+Scheduler page. They had already drifted: the JavaScript knew three profiles where PHP knew four.
+The system prompts still live in `Tools/ai_chat_worker.php`, because they have one reader and
+moving them would relocate the most delicate text in the subsystem without removing a duplicate.
+
+## ━━━ CONVERSATIONS ━━━
+
+Chats are stored server-side under `AI_DATA_DIR/ai_chats/`, one JSON file each, saved
+automatically when a turn completes and pruned to `AI_CHAT_HISTORY_MAX` (default 10, oldest
+first by creation).
+
+There is no Save button. A conversation worth keeping is not reliably one you knew was worth
+keeping while you were having it.
+
+The same store backs the AI tab and the Monitor tab's AI row, so a thread started on the
+dashboard is the one you carry on in the tab. Messages are re-validated per message on the way
+in — a stored chat is replayed into a later prompt when reopened, so an unchecked role written
+there would be an injection that survives a reload rather than one turn.
+
+Reopened chats render as plain turns: sources, reasoning and timings describe one generation and
+are not stored, because redrawing them beside a transcript that may be continued under a
+different profile would be citing evidence for an answer no longer being made.
+
+### Secrets are redacted on the way to disk
+
+A conversation about settings is a conversation containing credentials — asking for an API key to
+be changed means typing one. Message bodies are redacted in `vv_ai_chat_save()`, and the question
+is redacted again before it reaches `ai.log`.
+
+**On the way out, never in flight.** The live turn keeps the real value, because the model needs
+it to carry out what was asked. What it does not need is that value still in the transcript a week
+later — and a stored chat is replayed into a later prompt when reopened, so an unredacted one
+would hand the credential back on every subsequent turn, indefinitely.
+
+Two passes, because they catch different things:
+
+| Pass | Catches | Method |
+|---|---|---|
+| Known values | a credential this host already holds | exact match against secret-shaped conf keys, longest first |
+| Assignment shapes | a credential arriving that is not in the conf yet | `NAME=value`, `"api_key": value`, "set the token to …" |
+
+The second pass is the one that matters for settings changes: *"change the Emby API key to X"* is
+a secret arriving, and X matches nothing on disk until after the write it is requesting.
+
+Ordinary prose is left alone — the patterns anchor on a secret-shaped *name*, so `CACHE_WARN_GB=100`
+and "turn off the zfs scrub" pass through untouched. `vv_conf_key_is_secret()` is shared with the
+conf audit log, so the two cannot disagree about what counts as a secret.
+
+## ━━━ TOKEN ACCOUNTING ━━━
+
+Every completed `ask` appends one row to `AI_TOKEN_DB` (`data/ai/ai_token_history.db`):
+
+```
+date|time|host|profile|source|prompt_tokens|completion_tokens|tok_s
+2026-08-04|22:03:51|host1|varaverk|cli|2041|318|61.4
+```
+
+Both paths write it — this CLI (`source=cli`) and the WebGUI worker (`source=webgui`) — so the
+totals are not quietly the tab's alone. `ai_query.sh` passes `--token-db` and `--token-host`;
+called by hand without them, `cli.js` simply skips the row rather than guessing a path, because
+this file never reads conf itself.
+
+Read it on the plugin's AI tab, which aggregates today / last 7 days / all time, per host. Or
+straight from the shell, since it is just a delimited file:
+
+```bash
+# tokens used today
+awk -F'|' -v d="$(date +%F)" '$1==d {p+=$6; c+=$7} END {print p+c}' data/ai/ai_token_history.db
+```
+
+**The host column is where the turn ran, not where the file is read.** Each host writes only its
+own rows.
+
+`ai_token_sync.sh` pulls each partner's ledger into `$AI_TOKEN_CACHE_DIR/<slot>.tokens.db` (`/tmp/varaverk/ai/`) — the
+same trick `conf_sync.sh` uses for partner confs, and it runs from
+`INTERMEDIATE_MAINTENANCE_SCRIPTS` every four hours. The tab then reads every ledger it can see,
+so a fleet total is a fleet total.
+
+Pull only, no push: nothing here is needed by anyone else, and a reader that fetches its own data
+controls its own freshness instead of depending on the partner's cron. A partner file may only
+contribute rows whose `host` column matches its filename — a ledger copied into the wrong slot
+would otherwise be double-counted against a total that still looked plausible.
+
+The cache is tmpfs with **no save/restore pair**, unlike the conf cache. Stale counters are worse
+than absent ones: absent renders as "not collected here", stale renders as fact. An unreachable
+partner leaves its file alone and logs at info, because a partner being down for weeks is a
+normal state, not an incident.
+
+Pruning is by row count (`AI_TOKEN_RETAIN_ROWS`, default 20000) and happens on write, but only
+once the file passes a size threshold — an ordinary turn costs a `stat()` and an append. The CLI
+deliberately does not prune: duplicating a read-modify-write of the whole file in a second
+language is how the two drift apart.

+# ========================== AI Retrieval Index Builder ========================================
+# ==============================================================================================
+#
+# PURPOSE
+# ==============================================================================================
+# Builds and refreshes the retrieval index over Varaverk's own documentation — every script
+# header, folder README and Manual, and the conf templates. Chunks each file on the section
+# boundaries the header convention already defines, embeds each chunk through Ollama, and
+# stores the vectors in SQLite for AI/ai_query.sh to search.
+#
+# The index is derived data. It is gitignored, host-local, and rebuildable from the repo in
+# minutes — nothing depends on it surviving.
+#
+# ==============================================================================================
+# OPERATIONAL MODEL
+# ==============================================================================================
+# Chunking mirrors the header convention rather than using a fixed token window:
+#
+#   bash headers      split on the six section names, then sub-split named-paragraph
+#                     safeguards and principles so one question finds one answer
+#   PHP headers       same six names plus the per-layer tails (EXPORTS, RENDERS, ...)
+#   markdown          split on headings
+#   conf templates    split on the ━━━ section rules
+#
+# Every chunk keeps its section name as a field, which is what lets a query about a safeguard
+# be steered toward OPERATIONAL SAFEGUARDS chunks before similarity is considered.
+#
+# Incremental by file mtime. A file whose mtime has not moved is skipped without being read,
+# so a routine refresh costs well under a second and a full rebuild costs a few minutes.
+#
+# Heavy lifting runs in Node — float vector maths and SQLite BLOBs are genuinely awkward in
+# bash. This follows the api_cache_writer.sh precedent: a bash shim owning config, gating,
+# locking and logging, in front of the language that fits the work.
+#
+# ==============================================================================================
+# DESIGN PRINCIPLES
+# ==============================================================================================
+#
+# Tracked Files Only
+#   Indexes exactly what `git ls-files` reports. Configurations/, State_Files/ and data/ are
+#   gitignored, so it is structurally impossible for a credential to reach the index — the
+#   files holding them were never in the repo. This must never become a filesystem walk: a
+#   secret written into a vector cannot be rotated back out of it.
+#
+# The Index Is Disposable
+#   Stored under DATA_DIR, gitignored, and never synced to a partner. Losing it costs one
+#   rebuild. Nothing reads it as a source of truth — it points at files, and the files are
+#   the truth.
+#
+# Documentation Is The Corpus, Not The Code
+#   Script bodies are not indexed. The headers state intent and the code states mechanism;
+#   for the questions this answers, intent retrieves far better and is far cheaper.
+#
+# Off By Default
+#   Does nothing unless AI_ENABLED is true. A node with AI off never pays for this.
+#
+# ==============================================================================================
+# OPERATIONAL SAFEGUARDS
+# ==============================================================================================
+#
+# Fail-Closed Gate
+#   Exits cleanly unless AI_ENABLED is exactly "true". Any other value, including unset,
+#   means off.
+#
+# Root Enforcement
+#   Writes into DATA_DIR alongside other Varaverk state.
+#
+# Concurrency Lock
+#   acquire_lock() prevents two indexers racing on the same database.
+#
+# Dependency Verification
+#   Verifies node and the Ollama endpoint before touching the database. A missing dependency
+#   is reported and exits non-zero rather than leaving a half-built index.
+#
+# Reachability Pre-flight
+#   Probes the resolved Ollama URL with AI_CONNECT_TIMEOUT before starting. An unreachable
+#   endpoint aborts immediately instead of failing once per batch across the whole corpus.
+#
+# Partial Failure Is Not Recorded As Success
+#   A file whose chunks all failed to embed keeps its previous rows and its old mtime, so the
+#   next run retries it. A run with any failed batch exits 3.
+#
+# Atomic Per-Run Write
+#   All database changes commit in one transaction. An interrupted run leaves the previous
+#   index intact rather than a partially rewritten one.
+#
+# Deleted Files Are Removed From The Index

+#!/bin/bash
+# ==============================================================================================
+# ============================== AI Retrieval Query ============================================
+# ==============================================================================================
+#
+# PURPOSE
+# ==============================================================================================
+# Answers questions about Varaverk from Varaverk's own documentation. Embeds the question,
+# retrieves the closest chunks from the index AI/ai_index.sh built, and either prints them
+# directly or passes them to the generation model as grounding context.
+#
+# ==============================================================================================
+# OPERATIONAL MODEL
+# ==============================================================================================
+# Two modes over the same retrieval:
+#
+#   --search    print the matching chunks and their sources. No generation model involved,
+#               so it is fast and its output is verbatim repo text.
+#   (default)   retrieve, then ask the generation model to answer strictly from what was
+#               retrieved, citing each claim.
+#
+# Retrieval is steered by question shape. A question about what prevents something is pushed
+# toward OPERATIONAL SAFEGUARDS chunks, one about a variable toward CONFIGURATION, one asking
+# why toward DESIGN PRINCIPLES. This is a score boost, not a filter — a heuristic must not be
+# able to exclude the chunk that actually holds the answer.
+#
+# ==============================================================================================
+# DESIGN PRINCIPLES
+# ==============================================================================================
+#
+# Grounded Or Silent
+#   The prompt instructs the model to answer only from retrieved context and to say what is
+#   missing rather than fill the gap. This repo's conventions are frequently not the
+#   conventional ones, and a confident generic answer about rsync or Docker is worse here
+#   than no answer.
+#
+# Sources Are Always Shown
+#   Every answer prints the chunks it drew on. An answer that cannot be traced back to a file
+#   is not usable for changing anything.
+#
+# Search Is The Trustworthy Mode
+#   --search returns repo text with nothing generated. When an answer matters, use it.
+#
+# Read-Only
+#   Retrieves and answers. Nothing here writes conf, touches state, or runs another script.
+#
+# ==============================================================================================
+# OPERATIONAL SAFEGUARDS
+# ==============================================================================================
+#
+# Fail-Closed Gate
+#   Exits cleanly unless AI_ENABLED is exactly "true".
+#
+# No Root Required
+#   Reads the index and calls Ollama. Nothing it does needs privilege, so it does not ask for
+#   any — this is the one AI script an ordinary user should be able to run.
+#
+# Missing Index Is Reported, Not Built
+#   An absent index exits with guidance to run ai_index.sh. Building a corpus-wide index as a
+#   side effect of a question would turn a two-second query into a several-minute one.
+#
+# Reachability Pre-flight
+#   Probes Ollama with AI_CONNECT_TIMEOUT before embedding, so an unreachable endpoint fails
+#   immediately with a clear message.
+#
+# Bounded Generation
+#   The request is capped at AI_REQUEST_TIMEOUT. A wedged model cannot hang the caller.

+#
+# PURPOSE
+# ─────────────────────────────────────────────────────────────────────────────
+# Pulls each partner's AI token ledger into a RAM cache at /tmp/.cache/vv/ai/, so the AI tab
+# can report usage for the whole fleet instead of only the host the browser happens to be on.
+#
+# Each host records its own turns to data/ai_token_history.db and nothing syncs that file, so
+# without this a host can only ever see its own totals. The tab is careful to say "not collected
+# here" rather than 0 for a partner it cannot see; this script is what turns that into a number.
+#
+# Same trick as conf_sync.sh, and deliberately so — resolve the partner over Tailscale, scp one
+# small file into a tmpfs cache, let the reader treat a missing file as "unknown".
+#
+# ==============================================================================================
+# OPERATIONAL MODEL
+# ==============================================================================================
+#
+#   1. Gates — PARTNERSHIP_ENABLED, AI_ENABLED, AI_TOKEN_SYNC_ENABLED
+#   2. Per partner:
+#        a. Resolve their Tailscale IP
+#        b. Resolve their SCRIPTS_DIR from their varaverk.cfg (they may be in appdata mode)
+#        c. scp their data/ai_token_history.db → $AI_TOKEN_CACHE_DIR/<slot>.tokens.db
+#
+# Pull only, no push. conf_sync.sh pushes as well because a partner may be unable to reach us
+# and still needs our credentials; nothing here is needed by anyone else, and a reader that
+# fetches its own data controls its own freshness rather than depending on the partner's cron.
+#
+# ==============================================================================================
+# DESIGN PRINCIPLES
+# ==============================================================================================
+#
+# A missing file means unknown, never zero.
+#   The whole point of the tab reporting "not collected here" is that it is a different claim
+#   from "this partner spent nothing". If a partner is dark, unreachable or has never run a turn,
+#   there is simply no cache file, and the reader is expected to say so rather than render a 0
+#   that looks like a measurement.
+#
+# The reader pulls; nobody pushes.
+#   conf_sync.sh pushes as well, because a partner that cannot reach us still needs our
+#   credentials. Nothing here is needed by anyone else, so a host that wants fleet totals fetches
+#   them and owns its own freshness instead of depending on someone else's cron having run.
+#
+# RAM, not flash.
+#   The cache lands in tmpfs. It is a copy of a file that already exists on the partner and is
+#   rebuilt on the next pass, so writing it to flash would cost wear for something that is never
+#   worth surviving a reboot.
+#
+# Same shape as conf_sync.sh, deliberately.
+#   Resolve over Tailscale, scp one small file into a tmpfs cache, let a missing file mean
+#   unknown. A second transport pattern for a second small file would be a second set of
+#   failure modes to learn.
+#
+# ==============================================================================================
+# OPERATIONAL SAFEGUARDS
+# ==============================================================================================
+#
+#   An unreachable partner is not a failure.
+#       HOST2 is expected to be down for long stretches during onboarding. A warn every four
+#       hours would train the operator to ignore this script's output, and the AI diagnostic
+#       path treats every log WARN as actionable. Unresolvable partners are counted and
+#       reported once at info level; only a partner that resolves and then fails to transfer
+#       is treated as an error.
+#
+#   The cache is never written directly.
+#       scp lands on a .part file that is renamed into place, so a transfer interrupted halfway
+#       cannot leave the reader parsing half a ledger. A truncated final row would be skipped by
+#       the field-count check on the PHP side, but a torn file should not reach it at all.
+#
+#   Nothing is ever written back to the partner.
+#       This script only reads. A bug here cannot corrupt a partner's accounting.
+#
+#   The cache is tmpfs and deliberately not preserved.
+#       Unlike the conf cache there is no save/restore pair. Stale counters are worse than

+# ━━━━━ ARRS STACK — Manual ━━━━━
+
+Config reference, procedures, operational workflows.
+For overview see README-Arrs_Stack.md. For per-script detail see script headers.
+
+---
+
+## ━━━ ARR CLEANUP — FILE CLASSIFICATION ━━━
+
+Every file found on disk during an arr cleanup run falls into exactly one category:
+
+```
+TRACKED    → arr API returned this exact path                   → leave it alone
+PROTECTED  → matches ARR_PROTECTED_PATTERNS                     → never delete
+ORPHAN     → media extension, not tracked, old enough           → delete
+JUNK       → not a media extension, not protected               → delete (any age)
+RECENT     → not tracked, under ARR_ORPHAN_AGE days             → skip (may be mid-import)
+```
+
+**Why protected patterns are critical:** arrs generate artwork (`*.jpg`), metadata
+(`*.nfo`), and subtitles/lyrics that do NOT appear in the tracked file API response.
+Without protection, these would be classified as orphans and deleted — removing cover art
+from every album, every movie poster, every TV show thumbnail. Requires a full rescan
+to recover. Never remove artwork extensions from protected patterns.
+
+---
+
+## ━━━ ARR CLEANUP — SAFETY LAYERS ━━━
+
+All 7 layers must pass before any file is touched. There is no way to push through a
+failed safety check without the explicit override flag.
+
+```
+1. Container running + healthy      — a stopped container has an empty API
+2. API reachable                    — no API = no tracked file list = everything looks orphaned
+3. API version matches              — major version must match tested version in master.conf
+4. Item count > 0                   — no artists/series/movies = something is wrong with DB
+5. Tracked file count > 0           — empty response = everything would be deleted
+6. Tracked count >= MIN_TRACKED_PCT — dramatic drop from last run = abort and alert
+7. Deletion size < MAX_DELETE_GB    — last line of defense against misconfigured root path
+```
+
+Layer 7 is the catastrophic failure prevention. A misconfigured root path — pointing
+cleanup at the wrong directory — means the API returns zero tracked files for a root
+that actually contains thousands. Everything walks as an orphan. Everything gets deleted.
+`LIDARR/SONARR/RADARR_MAX_DELETE_GB` requires `--i-know-what-im-doing` to proceed past it.

+> A mismatch means every file on disk looks untracked — all appear as orphans.
+> MAX_DELETE_GB is the only thing standing between a path mismatch and losing your library.
+
+---
+
+## ━━━ SAFE TESTING PROCEDURE ━━━
+
+> **The arr cleanup scripts permanently delete files.** There is no recycle bin, no undo.
+> Follow this procedure on first use, after any root path change, after any API key change,
+> and after any significant arr library change.
+
+### Step 1 — Dry Run With Full Logging
+
+```bash
+lidarr_release_fixer.sh --dry-run --log
+lidarr_cleanup.sh --dry-run --log
+sonarr_cleanup.sh --dry-run --log
+radarr_cleanup.sh --dry-run --log
+```
+
+### Step 2 — Review the Output
+
+```
+Release fixer:
+  Are the "would fix" albums expected?
+  → Wrong release UUIDs switching to correct ones is expected behaviour
+  → If everything is already correct, nothing to do
+
+Cleanup:
+  Are TRACKED files the ones you expect?
+  → Known arr-managed files should show as TRACKED
+  → If they show as ORPHAN, the root path is wrong — STOP
+
+  Is the ORPHAN count reasonable?
+  → Healthy cleanup removes dozens to hundreds, not tens of thousands
+  → Large count = stop, investigate root path before proceeding
+
+  Are PROTECTED patterns working?
+  → Artwork (*.jpg) and subtitles (*.srt) must show as PROTECTED
+  → If they show as ORPHAN, check PROTECTED_PATTERNS config
+
+  Are RECENT files being correctly skipped?
+  → Files downloaded in the last 7 days should show as RECENT, not ORPHAN
+```
+
+### Step 3 — Check Numbers if Something Looks Wrong
+
+```bash
+# Root path mismatch? Compare these:
+# Lidarr UI: Settings → Media Management → Root Folders
+# Sonarr UI: Settings → Media Management → Root Folders
+# Radarr UI: Settings → Media Management → Root Folders
+# Must exactly match LIDARR_MUSIC_ROOT / SONARR_TV_ROOT / RADARR_MOVIES_ROOT
+
+# Is the arr running?
+docker ps | grep -E "Lidarr|Sonarr|Radarr"
+```
+
+### Step 4 — Run Live
+
+```bash
+# Only after dry run review passes.
+lidarr_release_fixer.sh
+lidarr_cleanup.sh
+sonarr_cleanup.sh
+radarr_cleanup.sh
+```
+
+### Step 5 — Verify in Arr UI
+
+```
+Library count  — should not have dropped significantly
+Missing files  — check if any monitored content shows as missing
+Emby library   — should show no ghost entries (notify_emby_scan handles this automatically)
+```
+
+---
+
+## ━━━ PROCEDURES ━━━
+
+### Adding a New Arr
+
+```bash
+# 1. Copy radarr_cleanup.sh as template
+cp Arrs_Stack/radarr_cleanup.sh Arrs_Stack/readarr_cleanup.sh
+
+# 2. Replace RADARR_ prefix with READARR_ throughout
+#    Update API endpoint, tracked file API path, extension list, protected patterns
+
+# 3. Add to host*.conf
+HOST1_READARR_URL="http://192.168.50.2:8787"
+HOST1_READARR_API_KEY="your-api-key"
+HOST1_READARR_BOOKS_ROOT="/mnt/user/Books"
+
+# 4. Add thresholds to master.conf
+READARR_ORPHAN_AGE=7
+READARR_MAX_DELETE_GB=50
+READARR_EXTENSIONS=("epub" "pdf" "mobi" "azw3" "cbz" "cbr")
+READARR_PROTECTED_PATTERNS=("*.jpg" "*.jpeg" "*.png" "*.nfo")
+
+# 5. Add to DAILY_MAINTENANCE_SCRIPTS in master.conf
+"Arrs_Stack/readarr_cleanup.sh"
+```
+
+Run `--dry-run --log` before scheduling.
+
+---
+
+### Managing the Arr Sync Blocklist
+
+```bash
+# Add item to blocklist (removes from all arrs + tombstones the ID)
+arr_sync.sh --blocklist-add lidarr <musicbrainz-artist-id> "reason"
+arr_sync.sh --blocklist-add sonarr <tvdb-series-id> "reason"
+arr_sync.sh --blocklist-add radarr <tmdb-movie-id> "reason"
+
+# Remove from blocklist (un-tombstones the ID — does NOT re-add to arrs)
+arr_sync.sh --blocklist-remove lidarr <id>
+
+# View all blocklisted IDs
+arr_sync.sh --blocklist-list
+```
+
+`--blocklist-add` is the only destructive operation — it simultaneously:
+1. Writes the tombstone entry to the blocklist TSV file
+2. Deletes the item from the local arr API (no file deletion)
+3. SSHes each remote node and deletes from their arr API
+
+Files become orphans on all nodes — arr_cleanup removes them on the next run.
+
+---
+
+## ━━━ TROUBLESHOOTING ━━━
+
+### Arr Cleanup Deleting Files It Shouldn't
+
+```
+1. Check the protected patterns — artwork and subtitles must be listed
+   LIDARR_PROTECTED_PATTERNS / SONARR_PROTECTED_PATTERNS / RADARR_PROTECTED_PATTERNS
+
+2. Check the root path matches arr settings exactly
+   Run: lidarr_cleanup.sh --status   (shows configured root path)
+   Compare: Lidarr UI → Settings → Media Management → Root Folders
+
+3. Check if files are truly orphaned
+   Run: lidarr_cleanup.sh --dry-run --log
+   Look for the specific file — verify it shows ORPHAN, not PROTECTED or TRACKED
+```
+
+### Lidarr Files Present But Not Importing
+
+```
+Symptom: album folder exists with properly tagged files, Lidarr shows 0 tracks imported.
+Cause:   Lidarr selected the wrong MusicBrainz release edition. The file's MBID doesn't
+         match Lidarr's foreignReleaseId, so track ID lookup fails.
+
+Fix:
+  lidarr_release_fixer.sh --dry-run --log
+  → Shows which albums would be corrected and which release UUIDs would change
+
+  lidarr_release_fixer.sh
+  → Applies corrections and queues RefreshArtist for affected artists
+
+If the file MBID doesn't match any Lidarr release (shows "MBID not in list"):
+  → File was tagged from a source Lidarr doesn't know about (unofficial, re-tagged)
+  → Manual import or re-tag with correct MBID
+```
+
+### Arr Cleanup Aborting at Safety Layer 6 (Tracked Count Drop)
+
+```
+API returned far fewer tracked files than last run.
+Possible causes:
+  - Arr database was recently rebuilt from scratch
+  - Large manual library removal
+  - Path map mismatch after arr migration
+
+If intentional (library intentionally reduced):
+  Delete LIDARR_TRACKED_COUNT_FILE to reset the baseline
+  Run cleanup once — it will establish a new baseline
+
+If unintentional:
+  Investigate before proceeding — the arr may have a problem
+```
+
+### Arr Sync Not Picking Up New Content
+
+```
+Is ARR_SYNC_ENABLED=true in master.conf?
+
+Can this host SSH to the remote without password?
+  → ssh -i [SSH_KEY] root@[remote-tailscale-ip] "hostname"
+
+Is the arr accessible on the remote?
+  → arr_sync.sh --status  (shows each node's arr reachability)
+  → arr_sync.sh --log     (verbose output per-node, per-arr)
+
+Is the item in the blocklist?
+  → arr_sync.sh --blocklist-list
+```
+
+### Emby Still Showing Ghost Entries After Cleanup
+
+```
+notify_emby_scan() is called automatically after every arr cleanup deletion.
+If ghosts persist:
+  1. Is Emby's API responding?
+     curl -s "http://[emby-ip]:8096/System/Info/Public"
+
+  2. Is EMBY_URL / EMBY_API_KEY correct in host*.conf?
+     Run: sonarr_cleanup.sh --status  (shows Emby config)
+
+  3. Trigger manually in Emby:
+     Library → Manage Library → Clean Missing Files
+```
+
+---
+
+## ━━━ OUTPUT TIERS ━━━
+
+All scripts have two output levels controlled by `--log`.
+
+Without `--log`, each script processes silently and always concludes with a summary
+block: identity, duration, counts (files removed, items added, arrs cleaned), and a
+status line. Warnings and errors are always visible.
+
+With `--log`, per-item detail appears: individual titles being processed, API query
+progress, per-node sync results, and per-file examination output. Use this when
+debugging unexpected results or validating configuration before the first scheduled run.
+
+Dry-run output follows the same tiers — `--dry-run` alone shows the summary of what
+would happen; `--dry-run --log` shows the full per-item preview list.

+# ━━━━━ ARRS STACK ━━━━━
+
+Lifecycle management for the arr suite (Lidarr, Sonarr, Radarr) across a multi-server
+ecosystem. Library sync so every node tracks the same content. Orphan cleanup against live
+arr APIs so deleted content actually leaves disk. Release correction so wrong MusicBrainz
+editions don't silently block Lidarr imports. Emby notified automatically after every
+deletion. Failed downloads recovered overnight. Artwork fetched continuously. Database
+hygiene for dropped upstream entries. Quality upgrades propagate to all nodes immediately
+via webhook. Weekly discovery adds new content based on what you actually play and watch.
+
+> **These scripts permanently delete files and modify arr databases.** Orphan cleanup is
+> protected by multiple safety layers that must all pass before anything is touched — but
+> dry runs and log review are still the right first step on any new system or after any
+> configuration change. See Manual-Arrs_Stack.md for the safe testing procedure.

+
+**Deleted Shows and Removed Albums Still on Disk**
+When you remove a series from Sonarr and the delete command fails — permission issue,
+container wasn't running, path mismatch — the files stay permanently. Over years on an
+active library this accumulates significantly.
+The fix: arr cleanup scripts query the live API for every tracked file path, walk the
+disk, and delete anything absent from the API response that's old enough to be past the
+import window.
+
+**Wrong MusicBrainz Release Edition Silently Blocking Lidarr Imports**
+Lidarr selects one specific release edition per album using a MusicBrainz release ID.
+When it picks the wrong edition (Brazil CD instead of US CD, Japan Digital instead of
+standard), the track IDs don't match what's embedded in the files. RescanFolders reports
+"Importing 0 tracks" even with perfectly tagged, complete files present. No error — just
+silence.
+The fix: `lidarr_release_fixer.sh` reads the MUSICBRAINZ_ALBUMID tag from each file,
+finds the matching release in Lidarr's known releases, switches the selection, and queues
+a RefreshArtist. Runs before cleanup so corrected albums are imported before the orphan
+scan ever sees them.
+
+**Emby Showing Ghost Entries After Cleanup**
+After arr cleanup deletes files, Emby still shows them until its next scheduled scan —
+potentially hours later. Users see broken entries that produce "file not found" errors.
+The fix: `notify_emby_scan()` is called automatically after every deletion. Triggers
+Emby's "Clean Missing Files" task immediately.
+
+**No Safety Net on Deletion Size**
+A misconfigured root path — pointing cleanup at the wrong directory — means the API
+returns zero tracked files for a root that actually contains thousands. Every file walks
+as an orphan. Everything gets deleted. This is the catastrophic failure mode.
+The fix: `LIDARR/SONARR/RADARR_MAX_DELETE_GB` — if total deletion size exceeds the
+limit, the script stops and requires `--i-know-what-im-doing` to proceed. The flag name
+is long and annoying by design. It cannot be added by accident.
+
+**Failed Downloads Accumulating Silently**
+Import failures and stalled downloads sit in arr queues indefinitely. Without
+intervention they occupy queue slots, block new searches, and the item never gets
+downloaded. Checking queues manually across three arrs is tedious.
+The fix: `arrs_failed_stalled_recovery.sh` inspects all arr queues, blocklists the bad
+release, removes it, and triggers a re-search. Runs daily.

+
+## ━━━ WHAT THIS FOLDER DOES ━━━
+
+**Library Sync**
+`arr_sync.sh` — full-mesh arr library sync across all nodes. Every node syncs with every
+other — union model, no hierarchy. Once arrs agree on what to track, rsync spreads the
+actual files.
+
+**Release Correction**
+`lidarr_release_fixer.sh` — reads MUSICBRAINZ_ALBUMID from FLAC and MP3 files, matches
+against Lidarr's known releases per album, switches monitored=true to the correct
+edition, queues RefreshArtist. Runs before lidarr_cleanup.sh daily. Handles both FLAC
+(vorbis comment block) and MP3 (ID3v2 TXXX frame).
+
+**Orphan Cleanup**
+`lidarr_cleanup.sh`, `sonarr_cleanup.sh`, `radarr_cleanup.sh` — API-verified orphan
+removal. Five classification categories (TRACKED/PROTECTED/ORPHAN/JUNK/RECENT), seven
+safety layers, automatic Emby notification after deletion.
+
+**Database Hygiene**
+`radarr_tmdb_removed.sh`, `sonarr_tvdb_removed.sh` — remove entries that upstream
+databases have dropped (TMDb/TVDB status="deleted"). These generate health warnings in
+arrs and can never be monitored or downloaded. Most are announced-but-never-released
+entries. Files are kept by default — most have none.
+
+**Library Recovery**
+`arrs_failed_stalled_recovery.sh` — detect and recover failed imports and stalled
+downloads across all arrs. Blocklists the bad release and triggers a re-search — hands-
+free overnight recovery.
+
+**Library Enrichment**
+`lidarr_missing_art.sh` — fetch missing album and artist artwork from fanart.tv and
+fallback sources. Never overwrites existing files.
+
+**Upgrade Propagation**
+`start_webhook_listener.sh` — Node.js HTTP server that receives Sonarr/Radarr/Lidarr
+OnUpgrade webhooks. Continuous; started at array start. Writes to
+`/var/log/varaverk/upgrade_webhook.log`.
+`upgrade_webhook_handler.sh` — triggered by the webhook listener. Pushes the upgraded
+item folder to every remote node immediately, then triggers an arr library rescan on
+each remote so the upgraded file is accepted without triggering a redundant quality search.
+
+**Discovery**
+`playback_aware_lidarr_discovery.sh` — behavior-driven music discovery. Scores your
+Emby play history, runs Last.fm getSimilar on top artists, adds the best matches to
+Lidarr. 0–5 meaningful adds per week.
+`playback_aware_radarr_discovery.sh` — behavior-driven movie discovery. Scores recently
+watched movies, runs TMDB recommendations on seeds, adds top candidates to Radarr.
+`playback_aware_sonarr_discovery.sh` — behavior-driven TV discovery. Scores recently
+watched series weighted by user diversity, runs TMDB TV recommendations on seeds, adds
+top shows to Sonarr. Multi-user design: one person binge-watching does not dominate seeds.

+
+## ━━━ EXECUTION ORDER ━━━
+
+**Daily via `daily_sync_maintenance.sh` (DAILY_MAINTENANCE_SCRIPTS):**
+
+```
+1. lidarr_release_fixer.sh   — correct wrong release editions before cleanup sees them
+2. lidarr_cleanup.sh         — orphan removal (music)

+```
+
+Note: `media_shares_permissions.sh` and `media_cleaner.sh` run before these from
+`Media/` — permissions and junk removal must complete first.
+
+**Every 30 min + 4hr via orchestrators (CRITICAL/INTERMEDIATE_MAINTENANCE_SCRIPTS):**
+
+```
+arrs_failed_stalled_recovery.sh   — failed/stalled queue recovery
+arr_sync.sh                       — library sync across all nodes
+```
+
+**Weekly via `weekly_sync_maintenance.sh` (WEEKLY_MAINTENANCE_SCRIPTS):**
+
+```
+playback_aware_lidarr_discovery.sh   — score play history → Last.fm similar → Lidarr
+playback_aware_radarr_discovery.sh   — score watch history → TMDB recommendations → Radarr
+playback_aware_sonarr_discovery.sh   — score episode history → TMDB TV → Sonarr
+```
+
+**Continuous (started by `array_started.sh`):**
+
+```
+start_webhook_listener.sh   — Node.js webhook server; dispatches upgrade_webhook_handler.sh
+```
+
+**On every arr upgrade (triggered by webhook):**
+
+```
+upgrade_webhook_handler.sh  — push upgraded folder to all remote nodes + trigger arr rescan
+```
+
+**Why release fixer before cleanup:** the fixer corrects Lidarr's release selection so
+files get imported. If cleanup ran first, a correctable album could accumulate age toward
+the orphan threshold before the fixer had a chance to fix it.
+
+**Why arr_sync before rsync:** once arrs agree on what to track, rsync spreads the actual
+files. An upgrade on one node — new tracked path, old path no longer in API — gets
+cleaned by arr_cleanup on all nodes after the next sync cycle.
+
+---
+
+## ━━━ HOST AWARENESS ━━━
+
+Scripts run on both servers via `detect_hosts()`, which aliases all `HOST*_` prefixed vars
+to their unprefixed names at runtime. No manual `HOST1`/`HOST2` comparisons exist in any
+script.
+
+`arr_sync.sh` keeps all arr databases in bidirectional union — either server can download
+to any share. Arr cleanup uses the union model: a file is only an orphan if the arr on
+this host doesn't have it indexed. Arr scripts check the aliased URL — if empty (arr not
+configured on this host), they exit cleanly with no action.
+
+`lidarr_release_fixer.sh` and `lidarr_missing_art.sh` exit cleanly on hosts without
+Lidarr configured — no HOST1_LIDARR_URL means nothing runs.

+
+## ━━━ THE NEWER LAYERS ━━━
+
+The original folder was "delete what the arrs no longer track". These were added as distinct
+failure modes surfaced — each exists because something went wrong that the cleanups could not
+have caught.
+
+### 🗑️  Download-Side Orphans — `arr_download_orphan_cleaner.sh`
+
+Every cleanup script here walks the **library** side. Nothing walked the **download** side —
+so completed downloads the arrs had stopped tracking accumulated in SABnzbd's Completed
+folders indefinitely. Discovered as **755 GB of orphaned TV downloads, oldest from 2022**,
+filling the cache pool to 89%.
+
+Classifies every entry as TRACKED / RECENT / JUNK / REDUNDANT / IMPORTABLE / UNMATCHED and
+acts only on the ones it can justify. The queue is a hard gate: if it cannot be read, the arr
+is skipped entirely, because without it there is no way to tell an active import from an
+orphan. A run total over `DOWNLOAD_ORPHAN_MAX_DELETE_GB` aborts — an abnormally large delete
+is the visible symptom of a partial queue fetch.
+
+### 🎭  Wrong-Root Detection — `sonarr_classification_scan.sh` + `radarr_classification_scan.sh`
+
+Overseerr lets any user request content into the wrong root folder — kids shows into general
+TV, anime into Kids_Tv_Shows. These classify every item from metadata alone (genre,
+certification, network/studio, original language) and report where the computed classification
+disagrees with the folder the item actually sits in.
+
+Report-only by default. `--move` acts on forward misplacements and adult-content-in-kids-root
+leaks. It deliberately does **not** move non-anime content out of the anime root — deliberate
+style placements (Western animation grouped with anime by choice) are genuine judgment calls.
+
+Both poll the arr's async move command to completion before verifying, because `moveFiles=true`
+flips the database instantly while the physical move is still queued behind others.
+
+### 🎨  Phantom Artists — `lidarr_duplicate_artist_cleanup.sh`
+
+MusicBrainz duplicates leave two Lidarr entries for one artist, one holding the files and one
+holding nothing. Removes only the zero-file side, with `deleteFiles=false` so nothing on disk
+is touched. Pairs where both sides hold files are flagged for review, never auto-resolved.
+
+Gated on the tracked-count floor shared with `lidarr_cleanup.sh` — during a library-wide desync
+both sides of a real duplicate can read as zero-file phantoms.
+
+### 🩺  Corruption + Reconciliation — `arr_corruption_scan.sh` + `arr_full_rescan.sh`
+
+`arr_corruption_scan.sh` ffprobes tracked video files for corrupt headers. Report-only unless
+`--remediate`, which deletes the file record and triggers an explicit re-search. Requires
+repeat detections across separate runs before acting, so a transient probe failure cannot
+delete a healthy file.
+
+`arr_full_rescan.sh` forces a genuine disk↔database reconciliation. Organic scans only touch
+files involved in an import, so an untouched library silently drifts — confirmed when Lidarr
+reported **~23% of its true track count** for 1,004 of 1,357 artists with no scan running and
+every file present on disk.
+
+### ⚡  Cache Warmth — `arr_cache_prefill.sh`
+
+Populates the shared tracked-data cache at array start and every 4 hours, so consumers never
+pay a cold fetch. Pure enhancement: nothing depends on it having run, and every consumer still
+writes through on a cold cache.

+# ==============================================================================================
+# ================================= Arr Cache Prefill ===========================================
+# ==============================================================================================
+#
+# PURPOSE
+# ─────────────────────────────────────────────────────────────────────────────
+# Populates the shared tracked-data cache (see arr_get_tracked_data() in common.sh) for
+# Lidarr, Sonarr, and Radarr. Without this, each arr's cache stays cold until whichever
+# script happens to touch that arr first writes through — which could be hours, depending
+# on the daily schedule. Originally Lidarr-only (lidarr_cache_prefill.sh, 2026-07-16),
+# generalized the same day to cover all three arrs once the cache mechanism itself was
+# generalized.
+#
+# Runs on two schedules (2026-07-17): once at array start (closes the cold-boot gap, 10min
+# wait ceiling for slow-starting containers) and again every 30min via
+# CRITICAL_MAINTENANCE_SCRIPTS with a 1min wait ceiling (ARR_PREFILL_WAIT_MINUTES=1 override)
+# — a live fetch+write takes seconds, so there's no reason to tolerate the boot-time wait on
+# a recurring job. This is what keeps the cache-first consumers' data reliably under 30min
+# old instead of only refreshing whenever some other script happens to write through.
+#
+# ==============================================================================================
+# OPERATIONAL MODEL
+# ==============================================================================================
+#
+# Each arr's container may still be starting when this fires (array just started) — retries
+# reaching that arr's API for up to ARR_PREFILL_WAIT_MINUTES before giving up on it and moving
+# to the next. Not fatal if one never comes up in time; that arr's cache just stays cold until
+# the next script writes through naturally, exactly as it would without this script existing.
+# An arr not configured on this host (e.g. Lidarr is HOST1-only) is skipped cleanly.
+#
+# ==============================================================================================
+# DESIGN PRINCIPLES
+# ==============================================================================================
+#
+# Warm the Cache, Never Own It
+#   This script only pre-populates what arr_get_tracked_data() would fetch on demand
+#   anyway. Nothing depends on it having run — every consumer still writes through on a
+#   cold cache. It removes latency and staleness, it is not a dependency.
+#
+# Failure Is a No-Op, Not an Error
+#   An arr that never comes up in time simply leaves its cache cold, exactly as if this
+#   script did not exist. That is why a missed prefill is logged rather than notified —
+#   the fallback path is the normal path.
+#
+# Wait Ceiling Matched to the Trigger
+#   The array-start run tolerates a long wait because containers are genuinely still
+#   starting. The 30-minute recurring run does not, because a live fetch takes seconds
+#   and a long wait there would only serve to overlap the next tick.
+#
+# Per-Arr Independence
+#   Each arr is prefilled on its own. One unconfigured or slow-starting arr never
+#   prevents the other two from being warmed.
+#
+# ==============================================================================================
+# OPERATIONAL SAFEGUARDS
+# ==============================================================================================
+#
+#   Root required       — chown-free here, but matches convention across Arrs_Stack/
+#   jq required         — skips the whole run cleanly (not fatal) if jq is missing
+#   acquire_lock        — prevents two invocations of this script overlapping (default strict
+#                         mode) — matters if the boot-time run is still waiting on a slow
+#                         container when the first 30min critical-tier tick fires
+#   Reachability retry  — tolerates a slow-starting container up to ARR_PREFILL_WAIT_MINUTES;
+#                         never fatal if one never comes up, that arr's cache just stays cold
+#   Active-rescan check — skips an arr this cycle if a rescan-type command is running, instead
+#                         of a live fetch arr_cache_write() would refuse to persist anyway
+#                         (2026-07-17) — avoids wasted API calls during a long rescan

+# strictly sequential, so the race condition that killed Healarr can't happen — there's
+# nothing running concurrently to race.
+#
+# Sonarr-only originally (2026-07-18/19); Radarr/Movies coverage added 2026-07-21 as a second
+# arr in the same per-file scan/strike/remediate loop, not a separate script — the detection,
+# strike, and state-file logic is identical, only the API shape (episodefile vs moviefile,
+# EpisodeSearch vs MoviesSearch) differs. Radarr's moviefile list is fetched batched
+# (movieId=... query params, BATCH_SIZE at a time) rather than off the movie list's embedded
+# .movieFile alone — Radarr supports a second tracked file per movie (alternate editions/
+# extras) that never shows up there, same gap radarr_cleanup.sh hit and fixed 2026-07-19;
+# reusing that batched-fetch shape here instead of the simpler single-file read so a
+# corruption scan doesn't silently skip every alternate edition in the library.
+#
+# ==============================================================================================
+# WHY A SEPARATE CONTAINER FOR FFPROBE
+# ==============================================================================================
+#
+# Neither Sonarr nor Radarr bundle ffprobe. ffprobe runs via `docker exec` into a
+# different container that does — confirmed live 2026-07-18:
+#   Jellyfin        — working ffprobe, mounts every share Emby does (Tv_Shows, Movies, kids/
+#                      anime shares, standup) as of 2026-07-18
+#   Emby            — mounts everything too, but its bundled ffprobe binary is broken
+#                      (2017-dated, fails to exec — likely a missing dynamic linker
+#                      dependency, not something to fix here)
+# Jellyfin is what's configured (HOST*_FFPROBE_CONTAINER).
+#
+# ==============================================================================================
+# OPERATIONAL MODEL
+# ==============================================================================================
+#
+# Runs Sonarr then Radarr, sequentially, never parallel — one arr failing/unconfigured never
+# blocks the other. Within each arr, one file at a time, in this order per file:
+#   1. Skip if unchanged (mtime+size) since the last time it verified clean — state file
+#      avoids re-probing the entire library every run, which would take far too long at
+#      this library size (90k+ tracked files).
+#   2. ffprobe via `docker exec` into FFPROBE_CONTAINER. Empty stderr + exit 0 = clean.
+#      Anything else = corrupt (same signature as Healarr: "Invalid data found when
+#      processing input", EBML header errors, etc.)
+#   3. Report-only by default. --remediate additionally:
+#        a. DELETE the specific episodefile/moviefile record via the arr's API
+#        b. Verify hasFile flipped false (never trust the DELETE response alone)
+#        c. Explicitly trigger EpisodeSearch/MoviesSearch for that episode/movie — this is
+#           deliberate, not left to the arr's own background missing-search cycle, because
+#           that cycle skips unmonitored items entirely. An explicit search call does not
+#           have that restriction (confirmed live: two unmonitored episodes Healarr healed
+#           both still got successfully re-grabbed via this exact same kind of search call,
+#           logged in Sonarr's history as "UserInvokedSearch").
+#
+# ==============================================================================================
+# DESIGN PRINCIPLES
+# ==============================================================================================
+#
+# Detect Always, Act Only on Request
+#   A bare run probes and reports. Deleting a file the arr believes it has is a
+#   destructive act, so it requires --remediate explicitly. The scan can be scheduled
+#   weekly and read without any risk of it removing media on its own.
+#
+# One Probe Result Is Not Evidence
+#   ffprobe can fail for reasons that have nothing to do with the file — a mid-write
+#   import, an NFS blip, a container restart. Corruption must be observed
+#   CORRUPTION_SCAN_STRIKE_LIMIT times consecutively before remediation acts, and a
+#   single clean re-probe resets the counter.
+#
+# Skip-Cache Over Re-Probing
+#   At 90k+ tracked files a full re-probe every run is not viable. Files unchanged by
+#   mtime and size since they last verified clean are skipped, so each run spends its
+#   time on what actually changed rather than re-proving the library from scratch.
+#
+# Delete the Record, Let the Arr Re-Acquire
+#   Remediation removes the file record and explicitly triggers a search. The arr is
+#   left to obtain a good copy through its normal path — this script never tries to
+#   repair a file in place.
+#
+# Explicit Search, Not the Background Cycle
+#   The re-search is triggered directly rather than left to the arr's own missing-search
+#   cycle, because that cycle skips unmonitored items entirely and would silently leave
+#   an unmonitored corrupt file deleted and never replaced.
+#
+# ==============================================================================================
+# OPERATIONAL SAFEGUARDS
+# ==============================================================================================
+#
+# Root Enforcement
+#   docker exec into the ffprobe container requires root.
+#
+# Lock Acquisition
+#   acquire_lock prevents overlapping runs. Two instances would both probe and could
+#   both count a strike against the same file, reaching the limit in half the intended
+#   number of observations.
+#
+# Host Detection
+#   detect_hosts() aliases the arr URLs, API keys and HOST*_FFPROBE_CONTAINER.
+#
+# jq Dependency Check
+#   Fails fast if jq is missing — the tracked-file lists and every hasFile verification
+#   are parsed with it.
+#
+# Report-Only Default
+#   Nothing is deleted without --remediate.
+#
+# ffprobe Configuration Check
+#   Exits cleanly if FFPROBE_CONTAINER / FFPROBE_BIN are unconfigured for this host.
+#
+# ffprobe Container Health Check
+#   check_container_health() verifies the container is running and healthy before any
+#   probing. Every probe is a docker exec into it — if it is stopped or unhealthy every
+#   exec fails, every file reads as corrupt, and two consecutive runs would clear the
+#   strike limit and hand --remediate the whole library to delete.
+#
+# API Reachability + Version Gate
+#   check_api then check_arr_version per arr. A version mismatch skips that arr rather
+#   than issuing deletes against an API whose file-record endpoints may have moved.
+#
+# Per-Arr Isolation
+#   Sonarr and Radarr run sequentially, and one failing, unconfigured or version-
+#   mismatched arr never blocks the other.
+#
+# Unmapped Path Skip
+#   Files whose arr-side path cannot be mapped into the ffprobe container's mount
+#   namespace are skipped and counted, never probed through a wrong path and never
+#   treated as corrupt because the probe could not see them.
+#
+# Strike Threshold
+#   CORRUPTION_SCAN_STRIKE_LIMIT consecutive corrupt detections are required before
+#   --remediate deletes anything. A transient ffprobe failure cannot trigger a delete,
+#   and a clean re-probe clears the counter.
+#
+# Post-Delete Verification
+#   The DELETE response is never trusted. hasFile is re-checked and must have flipped
+#   false before the re-search is issued, so a failed delete never leaves the arr
+#   searching for something it still believes it has.
+#
+# Targeted Deletion
+#   Only the specific episodefile/moviefile record for the corrupt file is removed —
+#   never the series, movie, or any sibling file.
+#

+# ==============================================================================================
+# ========================== Arr Download Orphan Cleaner =======================================
+# ==============================================================================================
+#
+# PURPOSE
+# ─────────────────────────────────────────────────────────────────────────────
+# Clears orphaned completed downloads out of the SABnzbd Completed folders that Sonarr and
+# Radarr import from. Anything sitting there that the arr's queue no longer references is an
+# orphan — the arr will never touch it again on its own, so without this script the folder
+# only ever grows.
+#
+# Built 2026-07-26 after exactly that: 755G of orphaned completed TV downloads (oldest from
+# 2022) had silently accumulated and filled the cache pool to 89%. Every existing cleaner
+# covers the library side (sonarr_cleanup.sh walks SONARR_TV_ROOT etc.) — nothing covered
+# the download side. This is that missing piece, using the same triage that recovered the
+# pool that day.
+#
+# ==============================================================================================
+# OPERATIONAL MODEL
+# ==============================================================================================
+#
+# Runs Sonarr then Radarr, sequentially. Per arr, every top-level entry in the configured
+# download dir is classified:
+#
+#   TRACKED    — basename matches a queue record's outputPath or title → leave it alone,
+#                the arr still knows about it
+#   RECENT     — mtime under DOWNLOAD_ORPHAN_AGE days → skip, may be mid-import
+#   JUNK       — no video file over DOWNLOAD_ORPHAN_MIN_VIDEO_MB → delete (par2 debris,
+#                samples, failed/never-extracted archives — the arr can't import these,
+#                and if the content is still wanted its own missing-search re-grabs it)
+#   REDUNDANT  — parse API matches it AND the library already has every episode / the
+#                movie file → delete (the arr already refused it as not-an-upgrade)
+#   IMPORTABLE — parse API matches it but the library is missing episodes / the movie
+#                → trigger DownloadedEpisodesScan/DownloadedMoviesScan on the folder and
+#                leave it; whatever imports gets swept as REDUNDANT next run, whatever
+#                the arr rejects (XEM-blocked, season-span files) stays HELD for a human
+#   UNMATCHED  — parse API can't match it (series/movie not in the arr) → delete. Past the
+#                age gate an entry the arr cannot even name is not going to import: if the
+#                title is in the library and monitored, clearing it lets the arr search a
+#                copy it can actually parse; if it is not in the library, nothing is
+#                tracking it and it is dead weight either way. Guarded — see Non-Empty
+#                Library Requirement below
+#   HELD       — IMPORTABLE entries the arr keeps refusing (XEM-blocked, season-span
+#                files), and everything skipped by a guard → report only, human call
+#
+# The queue fetch is a hard gate: if it fails, the whole arr is skipped — with no queue
+# there is no way to tell tracked from orphaned, and guessing means deleting active imports.
+#
+# ==============================================================================================
+# DESIGN PRINCIPLES
+# ==============================================================================================
+#
+# Classify Before Acting
+#   Every entry is placed in exactly one class before anything is deleted, and each class
+#   has its own justification. Nothing is removed because it merely looked unwanted — it is
+#   removed because it matched a category whose deletion rationale is written down above.
+#
+# The Queue Is the Source of Truth
+#   Tracked-vs-orphaned is decided by the arr's own queue, never inferred from filenames or
+#   timestamps. If the queue cannot be read, the arr is skipped entirely rather than
+#   falling back to a weaker signal — a guess here deletes an active import.
+#
+# Deleting Is Recoverable, Deleting Wrong Is Not
+#   The classes that get deleted are ones the arr can re-acquire: junk it could never
+#   import, content the library already has, and entries it cannot even name. Anything
+#   whose loss would be permanent or ambiguous is held and reported for a human instead.
+#
+# Abnormal Volume Means Broken Input
+#   The delete cap exists because the realistic failure mode is bad input, not bad logic —
+#   a partial queue fetch classifies live downloads as orphans, and the only visible
+#   symptom is an unusually large delete total. The cap turns that into a stop.
+#
+# ==============================================================================================
+# OPERATIONAL SAFEGUARDS
+# ==============================================================================================
+#
+# Root Enforcement
+#   Download folders are written by container users; removing them requires root.
+#
+# Lock Acquisition
+#   acquire_lock "wait" with an EXIT trap releasing all locks, so an interrupted run never
+#   strands a lock and the daily orchestrator is never silently skipped.
+#
+# Host Detection
+#   detect_hosts() runs before any HOST*_-prefixed download dir is resolved.
+#
+# DOWNLOAD_ORPHAN_CLEANER_ENABLED Toggle
+#   Master switch — exits cleanly when disabled.
+#
+# Download Path Restriction
+#   The download dir must exist and live under /mnt/. Anything else is refused rather
+#   than walked, so a blank or malformed path can never point the scan at the filesystem
+#   root or a system directory.
+#
+# Queue Fetch Hard Gate
+#   The arr is skipped entirely if its queue cannot be read. Without the queue there is no
+#   way to distinguish tracked from orphaned, and guessing deletes active imports.
+#
+# Age Gate
+#   Nothing under DOWNLOAD_ORPHAN_AGE days is touched, so an entry mid-import is never a
+#   deletion candidate regardless of how it classifies.
+#
+# Deletion Class Restriction
+#   Only JUNK, parse-verified REDUNDANT and UNMATCHED are deleted. IMPORTABLE entries and
+#   anything a guard has held are reported, never removed.
+#
+# Non-Empty Library Requirement
+#   UNMATCHED deletions require the arr to report a non-empty library. An empty or
+#   restoring database answers every parse with "no match", which would condemn the whole
+#   download dir. The library is queried directly rather than inferred from this run's own
+#   match rate — a small batch that is legitimately all-unmatched is normal once daily runs
+#   have caught up, and would otherwise read as a broken database.
+#
+# Delete Volume Cap
+#   A run total over DOWNLOAD_ORPHAN_MAX_DELETE_GB aborts the delete pass and notifies.
+#   --i-know-what-im-doing overrides it for a deliberate first run against a known backlog.
+#
+# Dry Run Support
+#   --dry-run classifies everything and reports, deleting and importing nothing.

+#
+#   HOST*_SONARR_DOWNLOAD_DIR / HOST*_RADARR_DOWNLOAD_DIR

+#
+#   HOST*_SONARR_DOWNLOAD_CONTAINER_DIR / HOST*_RADARR_DOWNLOAD_CONTAINER_DIR
+#       The same folder as the arr container sees it — used when triggering the

+#
+#   SONARR_URL / SONARR_API_KEY / RADARR_URL / RADARR_API_KEY

+#       (default: 7)
+#
+#   DOWNLOAD_ORPHAN_MIN_VIDEO_MB
+#       An entry with no video file above this size is JUNK (default: 50). Sonarr/Radarr only.
+#
+#   DOWNLOAD_ORPHAN_MIN_AUDIO_MB
+#       The same test for Lidarr (default: 2). Separate because a 50M floor would mark

+#
+#   DOWNLOAD_ORPHAN_KEEP_MARKER
+#       A file with this name inside a download folder pins it — the folder is never
+#       classified or deleted (default: .vv-keep). For lossless rips the library holds
+#       only at lower quality, which REDUNDANT would otherwise sweep.
+#
+#   DOWNLOAD_ORPHAN_MAX_DELETE_GB
+#       Per-run delete budget in GB (default: 100). A backlog above this is drained

+# ==============================================================================================
+# ======================= Arr Full Library Rescan =============================================
+# ==============================================================================================
+#
+# PURPOSE
+# ─────────────────────────────────────────────────────────────────────────────
+# Forces a genuine full disk↔database reconciliation for Lidarr/Sonarr/Radarr. Organic
+# scans (triggered by new imports, RSS sync, etc.) only touch the files actually involved —
+# an artist/series/movie that already has files sitting untouched on disk never gets its
+# file-tracking stats refreshed on its own. Confirmed 2026-07-16: Lidarr reported only ~23%
+# of its true trackFileCount with no active scan running, for 1,004 of 1,357 artists — files
+# verified present and readable on disk the whole time. Every downstream script (cleanup,
+# duplicate-artist detection, discovery) trusts these arr stats as source of truth for what's
+# on the share, so silent drift like this is exactly what check_tracked_count_floor() exists
+# to catch reactively. This job exists to catch it proactively instead of waiting for someone
+# to notice a suspiciously low number.
+#
+# Runs sequentially across all three arrs, never parallel — each is a heavy full-disk walk,
+# and running them concurrently would just contend for the same disk I/O for no benefit.
+#
+# ==============================================================================================
+# OPERATIONAL MODEL
+# ==============================================================================================
+#
+# Lidarr, then Sonarr, then Radarr — strictly sequential. Per arr:
+#
+#   1. Reachability
+#        → check_api; unreachable skips this arr only
+#
+#   2. Already-scanning check
+#        → a rescan already active (manual, or another script) means skip rather than
+#          stack a second full-disk walk on top of it
+#
+#   3. Capture the before count
+#        → tracked file count read from the arr's own stats
+#
+#   4. Trigger the rescan command
+#        → RescanFolders (Lidarr) / RescanSeries (Sonarr) / RescanMovie (Radarr)
+#
+#   5. Poll to completion
+#        → bounded by ARR_FULL_RESCAN_TIMEOUT
+#
+#   6. Report the delta
+#        → before vs after tracked count, so drift that was corrected is visible
+#
+# ==============================================================================================
+# DESIGN PRINCIPLES
+# ==============================================================================================
+#
+# Proactive, Not Reactive
+#   check_tracked_count_floor() catches stat drift reactively, at the moment some other
+#   script is about to act on bad numbers. This job exists so that drift is corrected on a
+#   schedule instead of being discovered by whichever cleanup happens to trip over it first.
+#
+# Sequential by Design
+#   Each rescan is a full-disk walk. Running three concurrently contends for the same
+#   spindles and finishes no sooner, so the arrs are never parallelised — the slowness is
+#   accepted deliberately rather than optimised into I/O thrash.
+#
+# Never Stack a Scan
+#   An already-running rescan is left alone rather than duplicated. A second concurrent
+#   walk of the same library doubles the I/O cost and returns nothing the first will not.
+#
+# Per-Arr Isolation
+#   One arr being down, slow, or already scanning must never prevent the other two from
+#   being reconciled. Partial coverage beats a skipped run.
+#
+# ==============================================================================================
+# OPERATIONAL SAFEGUARDS
+# ==============================================================================================
+#
+# Root Enforcement
+#   Kept for consistency across Arrs_Stack/ — this script makes no direct filesystem writes.
+#
+# Lock Acquisition
+#   acquire_lock "wait" — waits for a prior run rather than skipping or colliding. A full
+#   rescan across three arrs runs long and is worth queuing behind, not silently dropping.
+#
+# Host Detection
+#   detect_hosts() aliases each arr's URL and API key.
+#
+# jq Dependency Check
+#   Fails fast if jq is missing. Both the before/after tracked counts and the command
+#   payload are built with jq — without it the counts read empty and every delta would be
+#   reported as if nothing changed.
+#
+# Reachability Check
+#   check_api before touching an arr; unreachable skips that arr only.
+#
+# Active-Rescan Check
+#   Skips triggering a new rescan if one is already active on that arr, so a duplicate
+#   full-disk walk is never stacked. See Tools/arr_rescan_monitor.sh for catching that
+#   arr's cache up once the pre-existing scan finishes, rather than waiting a week.
+#
+# Sequential Only
+#   Two arrs' rescans never run in parallel.
+#
+# Per-Arr Isolation
+#   One arr failing, timing out, or being skipped never blocks the others.
+#
+# Timeout Bound
+#   ARR_FULL_RESCAN_TIMEOUT caps the wait per arr, so a rescan that never completes cannot
+#   hold the weekly window open indefinitely.
+#
+# Dry Run Support
+#   --dry-run reports which arrs would be rescanned and triggers nothing.

+# ─────────────────────────────────────────────────────────────────────────────
+# Detect and recover failed imports and stalled downloads across Sonarr, Radarr,
+# and Lidarr. Blocklists the bad release and triggers a re-search — hands-free
+# overnight recovery.
+#
+# ==============================================================================================
+# OPERATIONAL MODEL
+# ==============================================================================================
+#
+# Five problem types detected from the arr queue API:
+#   importFailed   — downloaded but arr couldn't import the file
+#   importPending  — downloaded, stuck waiting to import (will not self-resolve)
+#   importBlocked  — downloaded, but arr matched the release to the wrong media
+#                    by grab-history ID instead of by title and refuses to import
+#                    (permanent block, never self-resolves)
+#   error status   — serious failure not covered by the above two states
+#   stalled        — download stuck with no connections or no progress
+#
+# Never touches items with state "downloading" or "imported" — safe to run anytime.
+# Items newer than ARR_IMPORT_RECOVERY_AGE are skipped — gives arr time to retry first.
+#
+# importBlocked items get one extra check first (try_smart_import, Sonarr/Radarr only):
+# most are junk/duplicates and fall straight through to the normal 3-step response below,
+# but some are a release arr already correctly parsed — episode/movie identified, quality
+# and language known — that's just tripping the title-vs-grab-history safety net. If the
+# target has no file yet (missing) or the candidate is a same-language resolution upgrade
+# over what's already there, it's imported directly instead of being discarded. See
+# ARR_SMART_IMPORT_ENABLED in CONFIGURATION below.
+#
+# Per problem item that isn't smart-imported (3-step response):
+#   1. Blocklist the release  — prevents re-grabbing the same bad release
+#   2. Remove from queue      — cleans up the failed item
+#   3. Trigger new search     — finds a different release automatically
+#
+# ==============================================================================================
+# DESIGN PRINCIPLES
+# ==============================================================================================
+#
+# Hands-Free Recovery
+#   The script completes the full recovery cycle autonomously — blocklist, remove,
+#   re-search. No operator decision required. A failed import at midnight resolves
+#   itself before morning without any intervention.
+#
+# Smart Import Is Conservative By Design
+#   try_smart_import only acts when every file in the download is unambiguous: no
+#   rejections from arr's own analysis, and (no existing file) or (matching language
+#   plus a strictly higher resolution). Any ambiguity — mixed multi-episode files,
+#   unknown language, equal-or-lower quality, wrong language — falls straight through
+#   to blocklist+research, exactly today's behavior. It only ever adds a chance to
+#   keep something worth keeping; it never makes the no-smart-import case worse.
+#
+# Age Gate Before Action
+#   Items newer than ARR_IMPORT_RECOVERY_AGE are skipped. Arrs have their own
+#   retry logic — acting immediately would race against it. The age gate gives
+#   the arr time to self-resolve before this script escalates.
+#
+# Blocklist First
+#   The bad release is blocklisted before removal and re-search. Without this,
+#   the re-search can re-grab the same release that just failed.
+#
+# Circuit Breaker Per Media Item
+#   Some items can never resolve via blind retry — e.g. an album missing 1-2
+#   tracks where every available release is a different edition that doesn't
+#   match. Without a limit, the same media ID gets blocklisted + re-searched
+#   forever, every run, burning bandwidth and indexer queries for nothing.
+#   After ARR_RECOVERY_MAX_ATTEMPTS consecutive failures for the same
+#   (arr_type, media_id), the item is still blocklisted/cleaned from the queue
+#   but search is no longer auto-triggered — it's flagged chronic and left for
+#   manual review instead.
+#
+#   "Consecutive" is enforced, not just counted — a media_id's failure count
+#   is pruned at the end of every process_arr() pass if it no longer appears
+#   in that run's problem-item set (2026-07-19 fix: counts were never reset on
+#   success, so an item that failed a few times months apart and then imported
+#   fine could still get stuck permanently chronic from stale history).

+# API as Ground Truth

+#
+# Age Gate Before Deletion

+#   Lidarr's import pipeline writes files before registering them — acting
+#   immediately would delete files mid-import.
+#   Age is measured from ctime, not mtime — an import preserves the release's original
+#   mtime, so a file that landed today can read as years old and skip this gate. Depends
+#   on media_shares_permissions.sh touching only entries that are actually wrong.
+#
+# Seven-Gate Safety Model
+#   Multiple independent sanity checks must all pass before any file is touched.
+#   No single check is trusted in isolation — a misconfigured path returning an
+#   empty API response must not result in a wiped library.

+# ==============================================================================================
+# ======================= Lidarr Duplicate Artist Cleanup =======================================
+# ==============================================================================================
+#
+# PURPOSE
+# ─────────────────────────────────────────────────────────────────────────────
+# Detects and resolves duplicate artist entries in Lidarr's library — cases where the
+# same display name (case-insensitive) is backed by two different MusicBrainz artist
+# IDs. This happens when a search or list sync matches a same-named-but-different real
+# artist and adds it alongside the one already in the library. From that point on,
+# every completed download for that display name throws MultipleArtistsFoundException
+# and can never import — Lidarr correctly refuses to guess which of the two it means.
+#
+# ==============================================================================================
+# OPERATIONAL MODEL
+# ==============================================================================================
+#
+# For each case-insensitive duplicate artist name found:
+#
+#   Only one side has any tracked files
+#     → The zero-file side is a phantom — delete it (deleteFiles=false, nothing on disk
+#       to lose) and add its MusicBrainz ID to Lidarr's Import List Exclusions so it
+#       can't be silently re-added by a future list sync. Then trigger a refresh on the
+#       surviving artist so anything that was stuck on this exact ambiguity resolves
+#       immediately instead of waiting for Lidarr's own next check cycle.
+#
+#   Both sides have files, but their album titles don't overlap at all
+#     → Genuinely two different real artists sharing a name (e.g. a band's classic
+#       lineup vs. a later solo era with the same stage name). Not a bug — left alone.
+#
+#   Both sides have files AND overlapping album titles
+#     → The one case actually risky to automate: could mean real content is split
+#       across two entries and needs an actual merge, not a delete. Untouched,
+#       notified for manual review.
+#
+# ==============================================================================================
+# DESIGN PRINCIPLES
+# ==============================================================================================
+#
+# Never Delete Real Content
+#   Only the zero-tracked-file side of a pair is ever deleted. Anything with files is
+#   either left alone (disjoint albums) or flagged for a human (overlapping albums) —
+#   never auto-removed.
+#
+# Block Re-Addition At The Source
+#   A phantom that keeps coming back is worse than one that was never cleaned —
+#   Import List Exclusion is Lidarr's own mechanism for "never auto-add this again."
+#
+# Silent When Clean
+#   No duplicates found, or all duplicates are the simple phantom case — minimal
+#   output. Only ambiguous (overlapping-album) pairs produce a notification.
+#
+# ==============================================================================================
+# OPERATIONAL SAFEGUARDS
+# ==============================================================================================
+#
+# Root Enforcement
+#   Required by the container interaction and state writes.
+#
+# Lock Acquisition
+#   acquire_lock prevents overlapping runs racing on the same artist IDs.
+#
+# Host Detection
+#   detect_hosts() aliases LIDARR_URL / LIDARR_API_KEY.
+#
+# jq Dependency Check
+#   Fails fast if jq is missing — duplicate detection and every file-count read
+#   depend on it, and an absent jq would evaluate counts to empty and make every
+#   artist look like a zero-file phantom.
+#
+# API Reachability + Version Gate
+#   check_api then check_arr_version against LIDARR_VERSION_MAJOR before any read.
+#
+# Empty Library Abort
+#   A response of 0 artists aborts. An empty list is indistinguishable from
+#   "no duplicates" and must never be read as a clean result.
+#
+# Tracked-Count Floor
+#   check_tracked_count_floor against the baseline shared with lidarr_cleanup.sh.
+#   A library-wide desync — mid full-rescan, for example — makes trackFileCount read
+#   far below reality for many artists at once. Confirmed 2026-07-16: without this,
+#   both sides of a genuinely-real duplicate (ROMES) read as 0-file phantoms and the
+#   wrong one would have been deleted. Deliberately reuses lidarr_cleanup.sh's own
+#   baseline so every script depending on tracked counts shares one answer to "is
+#   Lidarr's data trustworthy right now" rather than forming a separate opinion.
+#
+# Files Never Deleted
+#   Removal passes deleteFiles=false. Only the phantom Lidarr entry is dropped;
+#   nothing on disk is touched, so a wrong call costs a re-add, not media.
+#
+# Phantom-Only Deletion
+#   Only the zero-file side of a duplicate pair is ever removed. If both sides hold
+#   files, or neither does unambiguously, the pair is flagged for manual review
+#   instead — the script never picks a winner between two real artists.
+#
+# Manual Review Reporting
+#   Flagged pairs are named in the summary and notification so an ambiguous
+#   duplicate surfaces as a decision to make rather than disappearing silently.
+#
+# Dry Run Support
+#   --dry-run reports every deletion and exclusion and performs none.

+#   or touches audio files. Re-running after a partial fetch completes exactly
+#   where it left off with no side effects.
+#
+# Source Fallback Chain
+#   Multiple sources are tried in order of quality preference. fanart.tv is
+#   primary; fallbacks exist so partial coverage is better than none. A failed
+#   primary never blocks the fallback from running.
+#
+# External API Courtesy
+#   Rate limiting and parallel job caps prevent hammering fanart.tv and other
+#   external APIs. Burst behaviour during large initial runs would risk
+#   temporary blocks that break future scheduled fetches.

+# ==============================================================================================
+# ============================= Lidarr Release Fixer ===========================================
+# ==============================================================================================
+#
+# PURPOSE
+# ─────────────────────────────────────────────────────────────────────────────
+# Fix Lidarr albums where the wrong MusicBrainz release edition was selected,
+# causing on-disk files to appear as unimported despite being present.
+#
+# Root cause: Lidarr tracks one specific release edition per album using
+# foreignReleaseId. When this doesn't match the MUSICBRAINZ_ALBUMID embedded
+# in the actual files, track ID lookup fails and RescanFolders imports 0 tracks
+# even with perfect, fully tagged files.
+#
+# Fix: Read the MusicBrainz Album ID from the first FLAC or MP3 found in each
+# album directory, look that release up in Lidarr's known releases for that
+# album, switch monitored=true to the correct one, then queue a RefreshArtist
+# to re-sync track IDs and trigger Lidarr's own import scan.
+#
+# ==============================================================================================
+# OPERATIONAL MODEL
+# ==============================================================================================
+#
+# For each monitored album with 0 tracked files:
+#   1. Locate the album directory under the artist's root path (title glob match)
+#   2. Find the first FLAC or MP3 file in that directory
+#   3. Read MUSICBRAINZ_ALBUMID from the file's tags
+#   4. Fetch the album's available releases from Lidarr
+#   5. If the file's release exists and differs from Lidarr's current selection:
+#      — PUT the album with the correct release set to monitored=true
+#      — Mark the artist for a RefreshArtist command
+#
+# RefreshArtist is batched — one per artist, even if multiple albums were fixed.
+# Lidarr handles the post-refresh rescan and import automatically.
+#
+# Cache-first artist list (2026-07-17) — comes from the shared tracked-data cache via
+# arr_get_tracked_data(), fresh (kept warm every 30min by arr_cache_prefill.sh), live fetch
+# as fallback. Everything below (per-album release lookups) still fetches live — that data
+# isn't part of what's cached.
+#
+# ==============================================================================================
+# DESIGN PRINCIPLES
+# ==============================================================================================
+#
+# Fixer Before Cleanup
+#   Runs before lidarr_cleanup.sh in the daily job list. The strike system in
+#   cleanup provides a protection window, but correcting releases first means
+#   files that were wrongly treated as orphans get imported rather than aged out.
+#
+# No Blind Fixes
+#   Only switches to a release that is already in Lidarr's known release list for
+#   that album. If the file's MBID isn't a recognized release, the album is skipped
+#   rather than guessed at. False corrections are worse than leaving it alone.
+#
+# Files Are Never Touched
+#   This script only modifies the Lidarr database record (release selection). Audio
+#   files, tags, and directory structure are read-only. All actual importing is
+#   handled by Lidarr after RefreshArtist runs.
+#
+# ==============================================================================================
+# OPERATIONAL SAFEGUARDS
+# ==============================================================================================
+#
+#   check_api                — API reachability verified before any processing
+#   check_arr_version        — aborts if Lidarr major version doesn't match LIDARR_VERSION_MAJOR
+#   artist count > 0         — aborts if artist fetch returns empty (API anomaly guard)
+#   release list validation  — only fixes to releases explicitly known to Lidarr for that album
+#   acquire_lock "skip"      — skips if another instance is already running
+#   detect_hosts()           — exits cleanly on hosts without Lidarr configured
+#   curl + jq + perl check   — fail fast if any required tool is missing

+# ==============================================================================================
+# ============================ Radarr Content Classification Scan ==============================
+# ==============================================================================================
+#
+# PURPOSE
+# ─────────────────────────────────────────────────────────────────────────────
+# Overseerr lets any user request a movie into the wrong root folder (kids content added to
+# the general Movies share, anime added to Kids_Movies, etc.) and most users never notice or
+# correct it. This script reads Radarr's tracked movie list and classifies every movie as
+# anime / kids-only / regular using metadata signals alone (genre, certification, studio,
+# original language) — then reports where a movie's computed classification disagrees with
+# the root folder it's actually sitting in, in both directions:
+#
+#   FORWARD  — a movie classified as anime/kids is sitting outside its dedicated root
+#   REVERSE  — a movie sitting inside the kids/anime root doesn't match that classification
+#
+# Report-only by default — no files are moved and no Radarr API writes happen unless a
+# mode flag is given. Pass --move to relocate forward misplacements, or --remove-junk to
+# delete and import-exclude bad-metadata entries (see OPERATIONAL MODEL below); without
+# those flags this is purely a detection tool. Every rule below was validated against
+# this library's real data before being
+# adopted (see master.conf comments above the curated lists) — this is not a generic
+# genre-matcher, it's tuned specifically against the false-positive traps that showed up
+# when testing looser rules (documented per-rule below).
+#
+# ==============================================================================================
+# CLASSIFICATION RULES
+# ==============================================================================================
+#
+# is_anime:
+#   (genre Animation AND originalLanguage Japanese) OR studio in RADARR_ANIME_STUDIOS
+#   Always wins over kids when both could apply — explicit priority, not a tiebreak.
+#
+# is_kids ("kids will end up watching this alone" — NOT "family movie night"):
+#   not is_anime AND certification not in (R, NC-17) AND (
+#     (genre Animation AND certification != PG-13)
+#     OR studio in RADARR_KIDS_STUDIOS
+#   )
+#   Deliberately excludes bare "Family" genre and bare "G" certification — both genuinely
+#   traced back to live-action films the whole household watches together (Mrs. Doubtfire,
+#   Doctor Dolittle, National Treasure-style adventures, classic Westerns), not kids-only
+#   content. Family movie night stays in the general Movies root by design.
+#
+#   The PG-13 exclusion on the Animation branch is load-bearing — without it this rule
+#   catches South Park movies, Sausage Party, "9", Resident Evil: Death Island, and (via
+#   the curated studio list) Warner Bros. Animation's R-rated Watchmen films, since that
+#   studio makes both kids content and adult content under the same name.
+#
+# is_junk (bad/thin TMDb match, not a real classification problem):
+#   hasFile == false AND imdbId == null AND tmdb votes < RADARR_JUNK_MIN_VOTES
+#   Caught live: two fake "X-Men"/"Wolverine" entries, two fake "Silent Hill" entries, one
+#   fake "The Purge" spinoff — all monitored placeholders with nothing behind them. The
+#   fix for these is removal from Radarr, not blocklist+redownload — there's no release to
+#   blocklist and likely nothing legitimate to redownload under that exact TMDb match.
+#
+# ==============================================================================================
+# OPERATIONAL MODEL
+# ==============================================================================================
+#
+# Report pass (always):
+#   check_api → check_arr_version → arr_get_tracked_data (cache-first, one call)
+#   → classify every movie → report FORWARD, REVERSE and JUNK findings
+#
+# Remove-junk pass (--remove-junk, runs first when combined with --move):
+#   One entry at a time, halting on the first failure.
+#   DELETE with deleteFiles=false and addImportExclusion=true — the Radarr entry is
+#   removed and blocked from re-adding, files on disk are never touched. is_junk
+#   requires hasFile == false, so there is no file behind these entries anyway.
+#   Verified by re-fetching and requiring a 404 before counting as removed.
+#
+# Move pass (--move):
+#   One movie at a time, verified after each.
+#   hasFile == true  → moveFiles=true, then poll the async MoveMovie command to
+#                      "completed" (bounded by RADARR_MOVE_POLL_TIMEOUT) before the
+#                      DB-field check — the DB flips instantly while the physical
+#                      move is still queued.
+#   hasFile == false → correct rootFolderPath/path and trigger MoviesSearch instead;
+#                      there is nothing to move.
+#
+# ==============================================================================================
+# DESIGN PRINCIPLES
+# ==============================================================================================
+#
+# Report by Default, Act Only on Request
+#   A bare run never calls Radarr's write API and never touches a file — every finding is
+#   just a candidate. Acting on them requires an explicit --move or --remove-junk flag, so
+#   the scan can be scheduled and re-run freely while the curated lists are being tuned
+#   without any risk of it rearranging the library on its own.
+#
+# Curated Lists, Not Bare Genre/Cert Matching
+#   Every signal used here failed at least once as a bare/standalone check during rule
+#   development (Family genre, G certification, blanket Animation genre, bare Anime genre
+#   tag, Disney+/general-platform networks) — see master.conf comments for what each
+#   curated list deliberately excludes and why.
+#
+# Cache-First, Never a Per-Movie Call
+#   Uses arr_get_tracked_data() same as radarr_cleanup.sh — Radarr's movie list already
+#   embeds everything this script needs per movie, so this is a single API call (or zero,
+#   if the shared cache is warm) regardless of library size.
+#
+# ==============================================================================================
+# OPERATIONAL SAFEGUARDS
+# ==============================================================================================
+#
+# Root Enforcement
+#   Required by the container interaction and state writes.
+#
+# Lock Acquisition
+#   acquire_lock, plus acquire_lock "wait" around the write passes with an EXIT trap
+#   releasing all locks, so an interrupted run never leaves a lock behind.
+#
+# Host Detection
+#   detect_hosts() aliases RADARR_URL / RADARR_API_KEY / the root literals.
+#
+# curl + jq Dependency Check
+#   Fails fast if either is missing — every classification signal is parsed with jq.
+#
+# Report-Only Default
+#   No write happens without --move or --remove-junk.
+#
+# Required Var Check
+#   require_var on RADARR_URL and RADARR_API_KEY before any request.
+#
+# API Reachability + Version Gate
+#   check_api then check_arr_version against RADARR_VERSION_MAJOR. A major version bump
+#   can move or rename the fields every rule depends on, so a mismatch aborts rather
+#   than classifying against an unknown schema.
+#
+# Empty Library Abort
+#   A response of 0 movies aborts — an empty list is indistinguishable from a clean
+#   library and would otherwise report success during an API fault.
+#
+# Unconfigured Root Skip
+#   A blank kids/anime root skips that category's checks rather than comparing paths
+#   against an empty string.
+#
+# Files Never Deleted
+#   Junk removal passes deleteFiles=false. Only the Radarr entry is removed, and
+#   addImportExclusion=true stops it being re-added. is_junk additionally requires
+#   hasFile == false, so these entries have nothing on disk in the first place.
+#
+# One At A Time, Stop On First Failure
+#   Both write passes process one entry at a time and halt on the first failure rather
+#   than continuing through the library.
+#
+# Post-Write Verification
+#   Removal is confirmed by re-fetching and requiring a 404. Moves are confirmed by
+#   re-fetching and checking rootFolderPath and hasFile. The API response alone is
+#   never treated as proof.
+#
+# Async Move Completion Polling
+#   moveFiles=true flips the DB instantly while the physical move is a separate async
+#   MoveMovie command. Each move polls its own command to "completed" (bounded by
+#   RADARR_MOVE_POLL_TIMEOUT) before the DB-field check, so a batch cannot report
+#   everything moved while files are still queued at the old path.
+#
+# Junk Vote Threshold
+#   RADARR_JUNK_MIN_VOTES gates junk detection alongside hasFile == false and a null
+#   imdbId. All three must hold — a thin-metadata entry that actually has a file, or
+#   has an IMDb ID, is never treated as junk.
+#
+# Post-Write Cache Refresh
+#   The tracked-data cache is refreshed after writes so no other arr script reads a
+#   stale rootFolderPath or a movie that no longer exists.

+# ==============================================================================================
+# ================================= Radarr Cleanup =============================================
+# ==============================================================================================
+#
+# PURPOSE
+# ─────────────────────────────────────────────────────────────────────────────
+# Delete orphaned movie files not tracked by Radarr. Queries the API for all
+# tracked movie file paths, walks the library on disk, and removes anything
+# untracked that is old enough to be past the import window. Triggers an Emby
+# library clean after each deletion run so ghost entries disappear immediately.
+#
+# The tracked-count floor check (Safety Layer 6) is rescan-aware: if Radarr's own
+# RescanMovie/DownloadedMoviesScan is active (independently of this script's own
+# lighter ProcessMonitoredDownloads pre-flight), a genuinely low mid-scan count gets
+# waited out (calibrated to that command's historical duration via
+# arr_get_rescan_duration(), up to 3 strikes) and re-fetched rather than triggering a
+# false-alarm abort. Mirrors the same fix built for lidarr_cleanup.sh 2026-07-16 after
+# a whole-library rescan there made trackFileCount read 22% of normal mid-scan.
+#
+# Cache-first movie list (2026-07-17), batched moviefile fetch (2026-07-19). The movie list
+# comes from the shared tracked-data cache via arr_get_tracked_data() — fresh (kept warm
+# every 30min by arr_cache_prefill.sh), live fetch as fallback. Radarr's movie list embeds
+# movieFile.path directly on every hasFile=true entry, but that's only the *primary* file —
+# Radarr 6+ supports a second tracked file per movie (alternate editions/extras) that never
+# shows up there, so relying on it alone misclassified a movie's second edition as an orphan
+# (confirmed live 2026-07-19: The Crash, They Will Kill You, The Drama, Lee Cronin's The
+# Mummy, and Ready or Not: Here I Come all had a legitimately-tracked second file deleted-flagged
+# this way). /moviefile?movieId=X returns every file for a movie, including secondaries, and
+# accepts movieId as a repeated query param for a bulk fetch — but the whole library in one
+# request 414s (Request-URI Too Long, confirmed live), so _fetch_tracked_files() batches
+# movieId params BATCH_SIZE at a time instead: ~14 requests for a ~2800-movie library rather
+# than the up-to-2896 individual per-movie calls the 2026-07-17 optimization eliminated, and
+# rather than the one-shot list read that missed secondary files. The filesystem is walked
+# once per run, not twice — classification records which paths are eligible for deletion as
+# it goes, and the delete pass (once the size-threshold check below passes) just acts on that
+# list instead of re-walking and re-classifying the whole tree. That single walk also gets
+# size+ctime straight from find -printf instead of a separate stat fork per file — find
+# already has to stat() every entry to know it's -type f, so this is free by comparison.
+# Measured ~130x faster per file (0.033ms vs 4.3ms).
+#
+# ==============================================================================================
+# OPERATIONAL MODEL
+# ==============================================================================================
+#
+# Every file encountered on disk is classified into one of five categories:
+#
+#   TRACKED   — Radarr API knows this exact path → leave it alone
+#   PROTECTED — matches RADARR_PROTECTED_PATTERNS → never delete
+#   ORPHAN    — video file, not tracked, older than RADARR_ORPHAN_AGE → delete
+#   JUNK      — not a video extension, not protected → delete regardless of age
+#   RECENT    — not tracked, under RADARR_ORPHAN_AGE → skip (may be mid-import)
+#
+# Radarr generates movie artwork (*.jpg), metadata (*.nfo), and manages subtitles
+# (*.srt, *.sub, *.ass) but does NOT include these in its tracked file API response.
+# Without PROTECTED classification these would be deleted — breaking Radarr and
+# Emby metadata display.
+#
+# After deletions: notify_emby_scan() triggers Emby "Clean Missing Files" task.
+# Emby removes ghost entries immediately — no user-facing file-not-found errors.
+#
+# ==============================================================================================
+# DESIGN PRINCIPLES
+# ==============================================================================================
+#
+# API as Ground Truth
+#   What Radarr tracks is authoritative. Files not in the API response are
+#   orphans — Radarr has no record of them and they serve no purpose.
+#   The script never infers ownership from directory structure alone.
+#
+# Age Gate Before Deletion
+#   Files under RADARR_ORPHAN_AGE are left alone regardless of tracked status.
+#   Radarr's import pipeline writes files before registering them — acting
+#   immediately would delete files mid-import.
+#   Age is measured from ctime, not mtime — an import preserves the release's original
+#   mtime, so a file that landed today can read as years old and skip this gate. Depends
+#   on media_shares_permissions.sh touching only entries that are actually wrong.
+#
+# Emby Cleanup Is Part of the Job
+#   Deleting a file without telling Emby leaves ghost entries that show as
+#   broken items. Triggering the Emby clean is not optional — it completes
+#   the deletion from the user's perspective.
+#
+# ==============================================================================================
+# OPERATIONAL SAFEGUARDS
+# ==============================================================================================
+#
+# Seven gates — ALL must pass before any file is touched:
+#   1. Container running and not starting/unhealthy
+#   2. API reachable
+#   3. API version matches RADARR_VERSION_MAJOR in master.conf
+#   4. Movie count > 0
+#   5. Tracked file count > 0
+#   6. Tracked count >= RADARR_MIN_TRACKED_PCT % of last known count
+#   7. Deletion size < RADARR_MAX_DELETE_GB — or --i-know-what-im-doing required
+#
+#   acquire_lock "wait"  — large scans take time, wait for previous run to finish
+#   jq + curl validation — exits if either tool missing
+#   ARR_DOCKER_TIMEOUT   — container checks protected against daemon hangs (script-local, not common.sh's DOCKER_TIMEOUT)
+#   notify_emby_scan()   — triggers Emby clean after deletion
+#   Silent by default    — orphans/junk warn(), clean library logs silently
+#
+# ==============================================================================================
+# STATE FILES
+# ==============================================================================================
+#
+#   RADARR_TRACKED_COUNT_FILE — persistent baseline for the tracked % safety check (gate 6)
+#       Updated after each successful run. Protects against misconfigured root path
+#       returning an empty API response and deleting the entire library.
+#
+# ==============================================================================================
+# CONFIGURATION
+# ==============================================================================================
+#
+# host*.conf
+#
+#   HOST*_RADARR_URL / HOST*_RADARR_API_KEY / HOST*_RADARR_MOVIES_ROOT
+#   HOST*_RADARR_PATH_MAP — container path → host path translation
+#   All aliased by detect_hosts() — script uses unprefixed names
+#
+# master.conf
+#
+#   RADARR_ORPHAN_AGE          — days before untracked file eligible for deletion
+#   RADARR_MAX_DELETE_GB       — require --i-know-what-im-doing above this
+#   RADARR_MIN_TRACKED_PCT     — abort if tracked count drops below this % of last run
+#   RADARR_TRACKED_COUNT_FILE  — persistent baseline file path
+#   RADARR_EXTENSIONS          — video file extensions for orphan classification
+#   RADARR_PROTECTED_PATTERNS  — file patterns never deleted
+#   RADARR_VERSION_MAJOR       — expected Radarr major version for API safety check
+#   RADARR_IMPORT_SCAN_TIMEOUT — seconds to wait for pre-flight import scan (default 600)
+#   ARR_CLEANUP_STATS          — stats file path (read by coffee report)

+# ─────────────────────────────────────────────────────────────────────────────
+# Same problem as radarr_classification_scan.sh, TV side: Overseerr lets any user request a
+# show into the wrong root folder (kids shows added to the general TV share, anime added to
+# Kids_Tv_Shows, etc.). This script reads Sonarr's tracked series list and classifies every
+# series as anime / kids-only / regular using metadata signals alone (genre, certification,
+# network, original language) — then reports where a series' computed classification
+# disagrees with the root folder it's actually sitting in, in both directions:
+#
+#   FORWARD  — a series classified as anime/kids is sitting outside its dedicated root
+#   REVERSE  — a series sitting inside the kids/anime root doesn't match that classification
+#
+# Report-only by default. Every rule below was validated against this library's real data
+# before being adopted — see the companion comment block in master.conf above the curated
+# lists. Pass --move to actually act (see MOVE MODE below) — nothing writes to Sonarr unless
+# that flag is given.
+#
+# ==============================================================================================
+# CLASSIFICATION RULES — DIFFERENT FIELD MODEL THAN RADARR, NOT A COPY-PASTE
+# ==============================================================================================
+#
+# TV metadata (TheTVDB, via Sonarr) shapes these signals differently than movie metadata
+# (TMDb, via Radarr) — every difference below was confirmed live, not assumed:
+#   - Sonarr has an explicit "Anime" genre tag; Radarr does not.
+#   - Sonarr uses a single "network" field (TheTVDB's broadcaster), not "studio".
+#   - Certification is on the US TV Parental Guidelines scale (TV-Y/TV-Y7/TV-G/TV-PG/
+#     TV-14/TV-MA), not the MPAA scale — the tiers do not mean the same thing at the same
+#     position (TV-G is "general audience", not "for children", unlike movie G).
+#
+# is_anime:
+#   genre "Anime" (corroborated by Japanese language OR a Japan network — the bare tag alone
+#     produced a real false positive: "Craig of the Creek", an all-American Cartoon Network
+#     show, carries an "Anime" genre tag on TheTVDB for no discernible reason)
+#   OR (genre Animation AND originalLanguage Japanese)
+#   OR network in SONARR_ANIME_NETWORKS
+#   Always wins over kids when both could apply — explicit priority, not a tiebreak.
+#
+# is_kids ("kids will end up watching this alone" — NOT "family show night"):
+#   not is_anime AND (
+#     genre "Children"                      (NOT "Family" — see below)
+#     OR certification in (TV-Y, TV-Y7)     (NOT TV-G — see below)
+#     OR network in SONARR_KIDS_NETWORKS
+#   )
+#   "Family" genre and "TV-G" certification were both tested standalone and rejected —
+#   both catch general-audience live-action content the whole household watches together
+#   (I Love Lucy, The Brady Bunch, Full House, Homestead Rescue), not kids-only content.
+#   Blanket "Animation" genre was also tested and rejected — it's dominated on TV by adult
+#   animated sitcoms (Rick and Morty, BoJack Horseman, Family Guy, South Park), unlike the
+#   movie side where it's a usable (gated) signal.
+#
+# No junk-detection tier here (unlike Radarr) — TheTVDB's ratings/imdbId data is far
+# sparser than TMDb's even for completely legitimate shows (confirmed live: "The Pussycat
+# Dolls Present: The Search for the Next Doll", a real 2007 MTV show, has ratings.votes=0
+# and imdbId=null) — the vote-count heuristic that works for Radarr would flag real content
+# for removal here, so it's deliberately not reused. --remove-junk from the Radarr script has
+# no Sonarr equivalent for the same reason.

+#
+# Acts on FORWARD misplacements (classified anime/kids, sitting in the wrong root) and on
+# REVERSE-KIDS leaks (adult certification sitting in the kids root — moved back to
+# SONARR_GENERAL_ROOT). Does NOT act on REVERSE-ANIME leaks — those are genuine judgment
+# calls, since deliberate style placements (Castlevania-type Western/Chinese animation
+# grouped with anime by choice) legitimately live in the anime root without matching the

+# episodeFileCount is Sonarr's equivalent of Radarr's hasFile — a series can have 0 files
+# (fully monitored, nothing downloaded) even while correctly classified. Those get their
+# rootFolderPath/path corrected and an immediate SeriesSearch triggered rather than a file
+# move (mirrors radarr_classification_scan.sh's handling of hasFile=false movies).
+#
+# One series at a time, verified after each. moveFiles=true flips the DB (rootFolderPath/
+# episodeFileCount) instantly, but the physical move is a separate async MoveSeries command
+# Sonarr drains one at a time internally — DB fields alone can report "moved" while the real
+# files are still sitting at the old path behind other queued moves (confirmed live: "Full
+# House" reported episodeFileCount:192 at the new path via API while the actual 75GB/192
+# files hadn't moved yet). Each move polls its own MoveSeries command to "completed" before
+# the DB-field check runs, so a batch can't compound the race the way a bare sleep-and-check did.
+#
+# ==============================================================================================
+# DESIGN PRINCIPLES
+# ==============================================================================================
+#
+# Curated Lists, Not Bare Genre/Cert Matching — see master.conf comments for exclusions.
+# Cache-First — arr_get_tracked_data() same as sonarr_cleanup.sh, single call regardless
+#   of library size. Refreshed after --move writes so no other script reads stale data.
+#
+# ==============================================================================================
+# OPERATIONAL SAFEGUARDS
+# ==============================================================================================
+#
+# Root Enforcement
+#   Required by the container interaction and state writes.
+#
+# Lock Acquisition
+#   acquire_lock prevents a scheduled run overlapping a manual --move.
+#
+# Host Detection
+#   detect_hosts() aliases SONARR_URL / SONARR_API_KEY / the root literals.
+#
+# curl + jq Dependency Check
+#   Fails fast if either is missing — every classification signal is parsed with jq,
+#   and a missing jq would evaluate each signal to empty and classify nothing.
+#
+# Report-Only Default
+#   Nothing is written to Sonarr without --move. The scan is safe to schedule and
+#   safe to run repeatedly while tuning the curated lists.
+#
+# Required Var Check
+#   require_var on SONARR_URL and SONARR_API_KEY before any request.
+#
+# API Reachability + Version Gate
+#   check_api then check_arr_version against SONARR_VERSION_MAJOR. A major version
+#   bump can move or rename the fields every rule here depends on, so a mismatch
+#   aborts rather than classifying against an unknown schema.
+#
+# Empty Library Abort
+#   A response of 0 series aborts. An empty list is indistinguishable from "nothing
+#   is misplaced" and would otherwise report a clean library during an API fault.
+#
+# Unconfigured Root Skip
+#   A blank SONARR_GENERAL_ROOT / KIDS_ROOT / ANIME_ROOT skips that category's
+#   checks rather than erroring — a host with no dedicated root is a valid setup,
+#   and a blank value must never be compared against as if it were a real path.
+#
+# One At A Time, Stop On First Failure
+#   Series are moved individually and the batch halts on the first failure rather
+#   than continuing. A misclassified root or a failing move is a condition to
+#   review, not to repeat across the library.
+#
+# Async Move Completion Polling
+#   moveFiles=true flips the DB instantly while the physical move is a separate
+#   async MoveSeries command Sonarr drains one at a time. Each move locates its own
+#   command and polls it to "completed" (bounded by SONARR_MOVE_POLL_TIMEOUT) before
+#   anything else is checked. Without this a batch reports every series moved while
+#   the files are still queued at the old path — and downstream orphan cleanup can
+#   act on that gap.
+#
+# Post-Move Re-Verification
+#   The PUT response is never trusted. The series is re-fetched and both
+#   rootFolderPath and episodeFileCount are confirmed against expectations before
+#   the move counts as successful.
+#
+# Reverse-Anime Leaks Excluded From Moves
+#   Deliberate style placements (Western/Chinese animation grouped with anime by
+#   choice) legitimately sit in the anime root. Those are reported, never moved.
+#
+# Post-Write Cache Refresh
+#   The tracked-data cache is refreshed after --move writes so no other arr script
+#   reads a stale rootFolderPath.
+#
+# ==============================================================================================
+# CONFIGURATION
+# ==============================================================================================
+#
+# host*.conf
+#   SONARR_URL / SONARR_API_KEY / SONARR_TV_ROOT — existing, aliased by detect_hosts()
+#   SONARR_GENERAL_ROOT / SONARR_KIDS_ROOT / SONARR_ANIME_ROOT — rootFolderPath literals as
+#     reported by the API (e.g. "/tv", "/kids tv", "/ext-anime-shows") — leave blank on a
+#     host with no dedicated root for that category; the corresponding checks are skipped,
+#     not treated as an error.
+#
+# master.conf
+#   SONARR_ANIME_NETWORKS / SONARR_KIDS_NETWORKS — curated network allowlists
+#   SONARR_VERSION_MAJOR — expected API major version (reused from sonarr_cleanup.sh)

+# ==============================================================================================
+# ================================= Sonarr Cleanup =============================================
+# ==============================================================================================
+#
+# PURPOSE
+# ─────────────────────────────────────────────────────────────────────────────
+# Delete orphaned TV episode files not tracked by Sonarr. Queries the API for
+# all tracked episode file paths, walks the library on disk, and removes anything
+# untracked that is old enough to be past the import window. Triggers an Emby
+# library clean after each deletion run so ghost entries disappear immediately.
+#
+# The tracked-count floor check (Safety Layer 6) is rescan-aware: if Sonarr's own
+# RescanSeries/DownloadedEpisodesScan is active (independently of this script's own
+# lighter ProcessMonitoredDownloads pre-flight — e.g. during a large missing-episode
+# search campaign), a genuinely low mid-scan count gets waited out (calibrated to that
+# command's historical duration via arr_get_rescan_duration(), up to 3 strikes) and
+# re-fetched rather than triggering a false-alarm abort. Mirrors the same fix built for
+# lidarr_cleanup.sh 2026-07-16 after a whole-library rescan there made trackFileCount
+# read 22% of normal mid-scan.
+#
+# Cache-first, both layers (2026-07-17). The series list itself comes from the shared
+# tracked-data cache via arr_get_tracked_data() — fresh (kept warm every 30min by
+# arr_cache_prefill.sh), live fetch as fallback. The per-series episodefile walk below still
+# always fetches live (that's the actual disk-truth this script's delete decisions depend
+# on), but write-throughs its result to arr_item_cache_write() for any future script that
+# needs Sonarr's per-episode data — no second consumer exists yet, unlike Lidarr's
+# lidarr_missing_art.sh, but the data's there once one does. The filesystem is walked once
+# per run, not twice — classification records which paths are eligible for deletion as it
+# goes, and the delete pass (once the size-threshold check below passes) just acts on that
+# list instead of re-walking and re-classifying the whole tree. That single walk also gets
+# size+ctime straight from find -printf instead of a separate stat fork per file — find
+# already has to stat() every entry to know it's -type f, so this is free by comparison.
+# Measured ~130x faster per file (0.033ms vs 4.3ms).
+#
+# ==============================================================================================
+# OPERATIONAL MODEL
+# ==============================================================================================
+#
+# Every file encountered on disk is classified into one of five categories:
+#
+#   TRACKED   — Sonarr API knows this exact path → leave it alone
+#   PROTECTED — matches SONARR_PROTECTED_PATTERNS → never delete
+#   ORPHAN    — video file, not tracked, older than SONARR_ORPHAN_AGE → delete
+#   JUNK      — not a video extension, not protected → delete regardless of age
+#   RECENT    — not tracked, under SONARR_ORPHAN_AGE → skip (may be mid-import)
+#
+# Sonarr generates show artwork (*.jpg), metadata (*.nfo), and manages subtitles
+# (*.srt, *.sub, *.ass) but does NOT include these in its tracked file API response.
+# Without PROTECTED classification these would be deleted — breaking Sonarr and
+# Emby metadata display.
+#
+# After deletions: notify_emby_scan() triggers Emby "Clean Missing Files" task.
+# Emby removes ghost entries immediately — no user-facing file-not-found errors.
+#
+# ==============================================================================================
+# DESIGN PRINCIPLES
+# ==============================================================================================
+#
+# API as Ground Truth
+#   What Sonarr tracks is authoritative. Files not in the API response are
+#   orphans — Sonarr has no record of them and they serve no purpose.
+#   The script never infers ownership from directory structure alone.
+#
+# Age Gate Before Deletion
+#   Files under SONARR_ORPHAN_AGE are left alone regardless of tracked status.
+#   Sonarr's import pipeline writes files before registering them — acting
+#   immediately would delete files mid-import.
+#   Age is measured from ctime, not mtime — an import preserves the release's original
+#   mtime, so a file that landed today can read as years old and skip this gate. Depends
+#   on media_shares_permissions.sh touching only entries that are actually wrong.
+#
+# Emby Cleanup Is Part of the Job
+#   Deleting a file without telling Emby leaves ghost entries that show as
+#   broken items. Triggering the Emby clean is not optional — it completes
+#   the deletion from the user's perspective.
+#
+# ==============================================================================================
+# OPERATIONAL SAFEGUARDS
+# ==============================================================================================
+#
+# Seven gates — ALL must pass before any file is touched:
+#   1. Container running and not starting/unhealthy
+#   2. API reachable
+#   3. API version matches SONARR_VERSION_MAJOR in master.conf
+#   4. Series count > 0
+#   5. Tracked file count > 0
+#   6. Tracked count >= SONARR_MIN_TRACKED_PCT % of last known count
+#   7. Deletion size < SONARR_MAX_DELETE_GB — or --i-know-what-im-doing required
+#
+#   acquire_lock "wait"  — large scans take time, wait for previous run to finish
+#   jq + curl validation — exits if either tool missing
+#   ARR_DOCKER_TIMEOUT   — container checks protected against daemon hangs (script-local, not common.sh's DOCKER_TIMEOUT)
+#   notify_emby_scan()   — triggers Emby clean after deletion
+#   Silent by default    — orphans/junk warn(), clean library logs silently
+#
+# ==============================================================================================
+# STATE FILES
+# ==============================================================================================
+#
+#   SONARR_TRACKED_COUNT_FILE — persistent baseline for the tracked % safety check (gate 6)
+#       Updated after each successful run. Protects against misconfigured root path
+#       returning an empty API response and deleting the entire library.
+#
+# ==============================================================================================
+# CONFIGURATION
+# ==============================================================================================
+#
+# host*.conf
+#
+#   HOST*_SONARR_URL / HOST*_SONARR_API_KEY / HOST*_SONARR_TV_ROOT
+#   HOST*_SONARR_PATH_MAP — container path → host path translation
+#   All aliased by detect_hosts() — script uses unprefixed names
+#
+# master.conf
+#
+#   SONARR_ORPHAN_AGE          — days before untracked file eligible for deletion
+#   SONARR_MAX_DELETE_GB       — require --i-know-what-im-doing above this
+#   SONARR_MIN_TRACKED_PCT     — abort if tracked count drops below this % of last run
+#   SONARR_TRACKED_COUNT_FILE  — persistent baseline file path
+#   SONARR_EXTENSIONS          — video file extensions for orphan classification
+#   SONARR_PROTECTED_PATTERNS  — file patterns never deleted
+#   SONARR_VERSION_MAJOR       — expected Sonarr major version for API safety check
+#   SONARR_IMPORT_SCAN_TIMEOUT — seconds to wait for pre-flight import scan (default 600)
+#   ARR_CLEANUP_STATS          — stats file path (read by coffee report)

+# ======================= Upgrade Webhook Listener (continuous) ================================
+# ==============================================================================================
+#
+# PURPOSE
+# ─────────────────────────────────────────────────────────────────────────────
+# Starts a standalone Node.js HTTP server that receives Sonarr/Radarr/Lidarr
+# OnUpgrade webhooks and dispatches upgrade_webhook_handler.sh.
+#
+# Runs outside Unraid nginx — no session auth required. The shared secret in
+# the webhook URL is the only gate. Arrs on this host call:
+#
+#   http://<HOST_LAN_IP>:<WEBHOOK_PORT>/webhook?key=<WEBHOOK_SECRET>
+#
+# Runs as a continuous script started by array_started.sh. Execs node which
+# replaces this process — the PID stays the same for array_started.sh's check.
+#
+# Uses Node.js instead of php -S: php -S on Unraid PHP 8.4 silently drops
+# POST request bodies, making webhook payloads arrive empty.
+#
+# If WEBHOOK_SECRET is empty in master.conf: generates and saves one, then starts.
+# If WEBHOOK_PORT is 0: exits cleanly (disables the listener).
+#
+# ==============================================================================================
+# OPERATIONAL MODEL
+# ==============================================================================================
+#
+#   1. Check WEBHOOK_PORT — exit cleanly if 0 (listener disabled)
+#   2. acquire_lock "continuous" — exit cleanly if a healthy instance is already running
+#   3. Check WEBHOOK_SECRET — generate and persist one if empty
+#   4. exec node webhook_listener.js — replaces this process; PID stays the same
+#
+# exec is intentional: array_started.sh tracks the PID of this script to check
+# whether the listener is running. exec preserves that PID across the hand-off
+# to node.
+#
+# ==============================================================================================
+# DESIGN PRINCIPLES
+# ==============================================================================================
+#
+# Node.js Over php -S
+#   php -S on Unraid PHP 8.4 silently drops POST request bodies — webhooks arrive
+#   empty and the handler has no payload to act on. Node.js handles POST bodies
+#   correctly and has no equivalent silent-drop behaviour.
+#
+# Runs Outside nginx
+#   The listener binds directly to WEBHOOK_PORT — no nginx proxy, no session auth.
+#   The shared secret in the URL query string is the only gate. This keeps the
+#   webhook path independent of the auth stack.
+#
+# exec Preserves PID
+#   The script execs into node rather than forking it. array_started.sh stores the
+#   PID of this script to check liveness — exec ensures that PID continues to
+#   refer to the running node process after the hand-off.
+#
+# Continuous-Mode Lock, Not Just PID Tracking
+#   array_started.sh only checks whether ITS launch attempt is still alive after
+#   1s — it has no idea a previous instance might already be listening (e.g. an
+#   array stop/start that didn't kill the old node process). Without its own
+#   guard, a relaunch would exec straight into node, hit EADDRINUSE on the port,
+#   exit 1 almost immediately, and array_started.sh would log a false failure
+#   for a listener that was actually still healthy. acquire_lock "continuous"
+#   detects the live instance and exits 0 instead.
+#
+# ==============================================================================================
+# OPERATIONAL SAFEGUARDS
+# ==============================================================================================
+#
+# Root Enforcement
+#   Writes /var/log/varaverk and persists the generated secret into master.conf.
+#
+# WEBHOOK_PORT=0 Gate
+#   Exits cleanly before any setup if the listener is disabled.
+#
+# node Presence Check
+#   node is exec'd at the end of this script. Checking up front fails with a clear
+#   reason at array start rather than an exec error buried in the log after setup.
+#
+# openssl Presence Check
+#   Checked before attempting to generate a secret, on the path that needs it.
+#
+# Lock Acquisition
+#   acquire_lock "continuous" exits 0 cleanly if a healthy instance is already
+#   listening, instead of relaunching into an EADDRINUSE port conflict. An array
+#   stop/start without a full reboot leaves the old node process alive, and without
+#   this array_started.sh would log a false failure.
+#
+# Secret Auto-Generation
+#   WEBHOOK_SECRET generated via openssl rand if empty, and persisted to master.conf
+#   so restarts reuse it.
+#
+# Secret Persistence Verification
+#   The write-back is confirmed by re-reading master.conf. If it did not land, the
+#   secret would exist only in this process and be regenerated on the next start,
+#   silently invalidating the key already registered in the arrs — so this aborts
+#   loudly rather than starting with a secret that will not survive a restart.

+# Triggered by Sonarr/Radarr/Lidarr OnUpgrade webhook (via webhook_listener.js).
+# Pushes the upgraded item folder to every other mesh node immediately, then

+#

+# ==============================================================================================

+# ==============================================================================================
+#
+# Invoked per import by webhook_listener.js with <arr_type> <item_path>:

+#        → API port, API version and rescan command for that arr type

+#   3. Discover remote nodes
+#        → discover_remote_nodes(); no remotes configured means exit cleanly
+#
+#   4. Per remote node, independently:
+#        a. Resolve its Tailscale IP — unresolvable skips that node
+#        b. rsync the single item to the same absolute path (--no-delete)
+#        c. Skip the rescan if rsync failed — never scan a partial file
+#        d. Trigger the arr's refresh command, cache-first API key with SSH fallback
+#
+# One failing node is counted and skipped; the rest still receive the upgrade.
+#
+# ==============================================================================================
+# DESIGN PRINCIPLES
+# ==============================================================================================
+#
+# Closes the Propagation Window
+#   arr_sync runs every 4 hours. Without this handler, a remote node that already
+#   has the old version sees the upgrade tagged in arr_sync but the new file not
+#   yet on disk, and initiates a redundant quality search — a search it will never
+#   win because this host already has the file. Immediate push eliminates that window.
+#
+# Rescan as Ground Truth
+#   Pushing the file is not enough — the remote arr must also be told the file
+#   exists. Triggering a rescan makes the remote accept the pushed file as the
+#   current version without starting a new search.
+#
+# Cache-First API Key Lookup
+#   Remote arr API keys are read from conf if cached; otherwise fetched via SSH

+#   rsync runs over SSH as root and writes to root@remote at the same absolute path.
+#
+# Argument Validation
+#   Exits with a usage message if arr_type or item_path is missing, and rejects an
+#   arr_type outside sonarr|radarr|lidarr rather than defaulting to one.
+#
+# Path Existence
+#   Exits if item_path is not a directory on disk.
+#
+# Item Path Depth Guard
+#   item_path must be an absolute path at least three levels deep. It arrives from the
+#   arr's webhook payload and is rsynced to the same path on the partner, so a truncated
+#   or malformed value would push a system directory — or the filesystem root — onto the
+#   remote. The existence check alone does not catch this, because / is a directory.
+#
+# No Lock — Deliberate
+#   This is an event handler invoked per import by webhook_listener.js. Concurrent
+#   upgrades are normal and expected. A default lock would silently drop overlapping
+#   events, and a waiting lock would queue them behind a slow transfer, so neither is
+#   used: each invocation rsyncs a different item path and they do not contend.
+#
+# Tailscale Resolution
+#   Skips a node if its Tailscale IP cannot be resolved, rather than attempting the
+#   transfer against an unresolved or stale address.
+#
+# rsync Exit Check
+#   The rescan is only triggered if rsync succeeded. A failed transfer never causes the
+#   remote arr to scan a partial file into its library.
+#
+# No Delete on Push
+#   rsync runs with --no-delete. This pushes one upgraded item; it is not a mirror, and
+#   must never remove content on the partner that this run does not know about.
+#
+# SSH Fallback
+#   If no cached API key is available, falls back to SSH to read config.xml on the
+#   remote rather than failing the rescan step.
+#
+# Per-Node Isolation
+#   One unreachable or failing node is counted and skipped; the remaining nodes still
+#   receive the upgrade.

-# Varaverk — Claude Code Context
-
-## Working Rules (read first)
-
-- **Workspace is always** `/boot/config/plugins/varaverk` — every edit goes here.
-- **No Co-Authored-By** in commit messages unless explicitly asked.
-- **No comments** unless the WHY is genuinely non-obvious.
-- The `.plg` symlinks the installed plugin location directly to this workspace — one copy, no drift.
-
-### Current workflow: edit here, push to Gitea
-
-Pre-release — too many moving parts for a dev/prod split right now. Edits are made directly in `/boot/config/plugins/varaverk/` and pushed. This is intentional, not a gap.
-
-### Future: dev/prod split (post-release)
-
-When the codebase stabilises, the plan:
-- **Dev** — a separate git clone somewhere on the array (`/mnt/user/Development/Varaverk/` or similar). All editing happens there.
-- **Prod** — `/boot/config/plugins/varaverk/` remains as-is. Only updated via `git pull` (already handled by `git_pull_execute.sh` in the daily orchestrator, or triggered manually from the UI).
-- **`plugin_setup.sh`** stays pointing at the prod path. Dev never touches `/boot/` directly.
-- **Push is the only bridge** — no deploy hooks, no rsync-on-save, no direct path references between dev and prod. The old dev folder was deleted precisely because it violated this.
-
-### Hard limits — do not cross these
-
-- **Never create or modify `.claude/settings.json`** in this repo. No workspace hooks, ever. The stale hook that existed here previously fired `Deployment/deploy.sh` (now deleted) on every file edit and caused unintended deploys. If you think a hook would help, ask first.
-- **Never change `HOST1_STORAGE_MODE_INTERNAL`** in `host1.conf`. Claude data belongs in `/mnt/user/appdata/claude-code/` — not inside this repo.
-- **There is no dev folder.** The old `/mnt/user/Important Shit/Git/Development/Varaverk` copy was deleted. Do not recreate it.
-- **Never move files between `Configurations/` and `Deployment/`** without explicit instruction. `Configurations/` = live runtime confs (gitignored). `Deployment/` = templates and setup tooling (tracked).
-
----
-
-## Project: What Varaverk Is
-
-Self-healing, self-maintaining, mutually-redundant two-server Unraid home media ecosystem.
-One codebase runs on both servers. No primary/standby — both run independently and cover each other.
-
-**HOST1 — unRAID-Gmer4Lfe** (`gmer4lfe@gmail.com`)
-- Hardware: Threadripper 1950X, 128 GB RAM, ZFS cache pools
-- Domain: Gmer4Lfe.com
-- Runs: full arr stack (Sonarr/Radarr/Lidarr), auth stack (source of truth), Emby primary
-
-**HOST2 — unRAID-Jayred365**
-- Hardware: Intel i5 10th gen, 64 GB RAM
-- Domain: Gmer4Lfe.us
-- Status: being rebuilt — most host2.conf sections scaffolded, not yet fully online
-
-Networking between hosts: Tailscale mesh. No hardcoded IPs — hostnames resolve via Tailscale.
-
----
-
-## Configuration System (three-file model)
-
-Every script sources all three at startup:
-
-```
-master.conf   ← shared: thresholds, toggles, profiles, orchestrator job lists
-host1.conf    ← HOST1 credentials, shares, container names, keys
-host2.conf    ← HOST2 credentials, shares, container names, keys
-```
-
-Sparse checkout (git) means each server only pulls its own `host*.conf`.
-HOST1 never sees HOST2 credentials and vice versa.
-
-**Rule:** thresholds/toggles → `master.conf`; credentials/paths/container names → `host*.conf`.
-
-`detect_hosts()` in `common.sh` matches `$(hostname)` against `HOST1`/`HOST2` in `master.conf`
-and sets `MY_ID` / `REMOTE_ID` for the rest of the script.
-
----
-
-## Platform Adapter Layer
-
-`Plugin/unraid/adapter.sh` isolates all OS-specific calls.
-Scripts never branch on OS directly — always call adapter functions.
-This is intentional architecture — don't bypass it.
-
----
-
-## Key Paths
-
-| Path | Purpose |
-|------|---------|
-| `master.conf` | Shared config — all thresholds, toggles, profiles |
-| `host1.conf` / `host2.conf` | Per-host credentials, shares, container lists |
-| `common.sh` | Shared functions — `detect_hosts()`, `log()`, `notify()`, etc. |
-| `load_config.sh` | Sources all three conf files + common.sh |
-| `State_Files/` | Runtime state (watchdogs, fallback, transcode) — survives reboots |
-| `data/` | Historical logs and stats |
-| `Plugin/unraid/` | Unraid WebGUI plugin (PHP pages, API endpoints, adapter) |
-| `Orchestrators/` | Top-level schedulers (array_started, daily, weekly, watchdog) |
-| `Watchdogs/` | docker_watchdog, system_watchdog, resource_watchdog, stability |
-| `Fallback/` | Mutual container failover logic |
-| `Rsync/` | rsync.sh + profile system |
-| `Media/` | Arr cleanup, discovery, permissions, play state sync |
-| `Tools/` | Manual one-off tools including `claude_startup.sh` |
-
----
-
-## Orchestrator Schedule
-
-| When | What |
-|------|------|
-| Array start | `Orchestrators/array_started.sh` → runs `ARRAY_START_SCRIPTS` |
-| Every minute | `watchdog_orchestrator.sh` → resource → docker → system → stability watchdogs |
-| Every 30 min | `critical_sync_maintenance.sh` → downloaders_reset, play_state_sync, critical rsync |
-| Every 4 hours | `intermediate_sync_maintenance.sh` → arr_sync, arrs_failed_stalled_recovery |
-| Daily 1am | `daily_sync_maintenance.sh` → git pull, permissions, cleaners, arr cleanup, docker updates |
-| Sunday 2:30am | `weekly_sync_maintenance.sh` → full Emby + Critical-Data sync, weekly restarts |
-| Sunday 3am+ | `monthly_maintenance.sh` (self-gated on 30-day uptime) → ZFS scrub, SMART tests |
-| Sunday 7am | `sunday_morning_coffee_report.sh` → ZFS, SMART, certs, backup verify, bandwidth, Emby report |
-
----
-
-## Rsync Toggle State (current)
-
-```bash
-RSYNC_ENABLED=true
-CRITICAL_RSYNC_ENABLED=true
-INTERMEDIATE_RSYNC_ENABLED=true
-DAILY_RSYNC_ENABLED=true
-WEEKLY_RSYNC_ENABLED=true
-FALLBACK_RSYNC_ENABLED=true
-```
-
----
-
-## Fallback System
-
-`fallback.sh` runs continuously from array start.
-States: `NORMAL | FALLBACK | NO_INTERNET | DARK`
-
-DDNS rules are absolute:
-- Internet loss → stop own DDNS immediately
-- Failover → start remote's DDNS as Tier 1 first
-- Handback → stop remote DDNS → rsync → start containers → start local DDNS last
-
-Tier delays before activating higher tiers are in `host*.conf` (`HOST1_TIER*_DELAY`, `HOST2_TIER*_DELAY`).
-
----
-
-## Port Notes
-
-- **NPM admin API (`HOST1_NPM_URL`)** — port **7818**. Port 81 is the partnership WebUI port (`HOST1_PARTNERSHIP_AUTH_WEBUIS`), not the API. Easy to confuse.
-- **HOST1_NETWORK_WATCHDOG_NPM_URL** — external HTTPS domain, completely separate from the admin API.
-
-## Known Gaps / Active Work
-
-- HOST2 NPM/lldap credentials (`HOST2_NPM_USER`, `HOST2_NPM_PASS`, `HOST2_LLDAP_PASS`) are empty in `host2.conf` — fill in when HOST2 is back online.
-- `PARTNERSHIP_ENABLED=false` — not yet active.
-- `FALLBACK_ENABLED=true` — fallback is running.
-
----
-
-## Claude Code Persistence on Unraid
-
-`/root` is a RAM filesystem — wiped on every reboot.
-`Tools/claude_startup.sh` runs at array start (via `ARRAY_START_SCRIPTS`) and:
-- Symlinks `/root/.claude` → `/mnt/user/appdata/claude-code/.claude`
-- Symlinks `/root/.local/share/claude` → `/mnt/user/appdata/claude-code/local/share/claude`
-- Symlinks `/root/CLAUDE.md` → `/boot/config/plugins/varaverk/CLAUDE.md` (this file)
-
-This file lives on `/boot` (USB flash) and is always available regardless of array state.
-
----
-
-## Commit Style
-
-Plain, concise messages. No Co-Authored-By trailers. No bullet-point summaries in the body.
-One sentence on the why, not the what.

+
+Procedures and flag reference for the schema layer.
+For overview see README-Deployment.md. For per-script detail see the script headers.
+
+---
+
+## ━━━ PROCEDURES ━━━
+
+### Adding a New Configuration Variable
+
+The single most common task here, and the one with the quietest failure mode if done wrong.
+
+```bash
+# 1. Add it to the template — this is the versioned schema
+#    Shared threshold/toggle  → Deployment/master.conf.template
+#    Per-host credential/path → Deployment/host.conf.template  (use the HOSTN_ prefix)
+
+# 2. Add it to your own live conf so you can test immediately
+#    Configurations/master.conf   or   Configurations/host1.conf
+
+# 3. Use it in the script, with a safe default
+#    [[ "${NEW_THRESHOLD:-50}" -gt ... ]]
+
+# 4. Commit the script change and the template change TOGETHER
+git add Deployment/master.conf.template Watchdogs/System/storage_watchdog.sh
+git commit -m "..."
+```
+
+**Step 1 is the one that gets skipped.** A script merged without its template entry works on
+the machine it was written on and nowhere else — the variable is simply empty on every other
+node, and the script takes whatever branch an empty value produces. Nothing errors.
+
+Placement rule, same as everywhere in the ecosystem:
+
+| Kind | Goes in |
+|------|---------|
+| Threshold, toggle, profile, job list | `master.conf.template` |
+| Credential, path, container name, per-host identity | `host.conf.template` |
+
+---
+
+### Previewing a Schema Change Before It Lands
+
+```bash
+bash Deployment/conf_upgrade.sh \
+    --template Deployment/master.conf.template \
+    --target   Configurations/master.conf \
+    --dry-run
+```
+
+Prints the full ADDED / REMOVED / KEPT report and writes nothing. No root required — safe to
+run as any user, on any target, at any time.
+
+Read the **REMOVED** list carefully. A key showing as REMOVED means it is in your conf but no
+longer in the template — either genuinely deprecated, or someone forgot step 1 above and the
+next pull will drop a setting you still rely on.
+
+---
+
+### Applying a Schema Change by Hand
+
+Normally automatic via `git_pull_execute.sh`. To run it manually:
+
+```bash
+bash Deployment/conf_upgrade.sh \
+    --template Deployment/master.conf.template \
+    --target   Configurations/master.conf \
+    --backup
+```
+
+`--backup` writes `master.conf.bak` first. Use it — see The Recovery Gap in the README for
+why the backup matters more here than it looks.
+
+For a host conf, the template must have its prefix resolved first, exactly as
+`git_pull_execute.sh` does it:
+
+```bash
+TMPL=$(mktemp)
+sed "s/HOSTN_/HOST1_/g; s/REMOTE_ID/HOST2/g" Deployment/host.conf.template > "$TMPL"
+bash Deployment/conf_upgrade.sh --template "$TMPL" --target Configurations/host1.conf --backup
+rm -f "$TMPL"
+```
+
+Merging the raw template without substituting `HOSTN_` would add 140 new `HOSTN_*` keys
+alongside your real `HOST1_*` ones, and mark every real key as REMOVED.
+
+---
+
+### Populating Credentials on a New Host
+
+```bash
+bash Deployment/conf_populate.sh --dry-run     # always first
+bash Deployment/conf_populate.sh
+```
+
+Reads from the services actually running on this host and fills **empty** fields only.
+Existing values are never touched without `--overwrite`.
+
+What it detects: arr API keys and ports from each `config.xml`, root folders from the arr
+rootFolder API, path maps from docker volume mounts, SABnzbd/slskd/qBittorrent credentials
+from their own config files, Emby/Jellyfin containers and ports, the boot device transport,
+and the default-gateway NIC.
+
+Then pushes the updated conf to partners via `conf_sync.sh` so they hold the fresh keys
+immediately. `--no-push` skips that.
+
+**If a field stays empty after a run,** check the output for an ambiguity warning:
+
+```
+WARN: Container prefix 'authelia' is ambiguous — matches: Authelia-Secondary Authelia
+WARN:   Refusing to guess. Set the container name manually in host*.conf.
+```
+
+That is working as intended. Set it by hand and re-run.
+
+---
+
+### After Rotating an API Key
+
+```bash
+bash Deployment/conf_populate.sh --overwrite --dry-run
+bash Deployment/conf_populate.sh --overwrite
+```
+
+`--overwrite` replaces detected fields even when already set. This is the intended use for it
+— rotating an arr key, rebuilding a container, or repointing at a moved service.
+
+Note it overwrites **every** detected field, not just the rotated one. Run the dry-run first
+and read the list.
+
+---
+
+### Rebuilding a Wiped Node
+
+The templates are what make this possible without copying another machine's credentials.
+
+```bash
+# 1. Clone the repo — templates come with it, confs do not (gitignored)
+# 2. Seed the confs from the templates
+cp Deployment/master.conf.template Configurations/master.conf
+sed "s/HOSTN_/HOST2_/g; s/REMOTE_ID/HOST1/g" Deployment/host.conf.template > Configurations/host2.conf
+
+# 3. Fill in what can be detected automatically
+bash Deployment/conf_populate.sh
+
+# 4. Fill in the rest by hand — anything conf_populate cannot see:
+#    hostnames, DDNS containers, fallback tier lists, sync share lists,
+#    partner credentials, Discord webhook
+```
+
+From then on, `git_pull_execute.sh` keeps the conf in step with the template automatically.
+
+---
+
+## ━━━ FLAG REFERENCE ━━━
+
+### `conf_upgrade.sh`
+
+| Flag | Required | What it does |
+|------|----------|-------------|
+| `--template <file>` | yes | Source of structure and new keys |
+| `--target <file>` | yes | Existing conf — source of real values, always preserved |
+| `--dry-run` | | Print the change report, write nothing. No root needed. |
+| `--backup` | | Write `<target>.bak` before installing |
+
+Takes no other flags. It does not source `load_config.sh`, so `--log` and `--status` do not
+exist here — see the script header for why that is deliberate.
+
+### `conf_populate.sh`
+
+| Flag | What it does |
+|------|-------------|
+| `--dry-run` | Show what would be written, truncated. Changes nothing. |
+| `--overwrite` | Replace detected fields even when already set |
+| `--no-push` | Skip pushing the updated conf to partners |
+| `--log` | Verbose per-field output |
+
+---
+
+## ━━━ TROUBLESHOOTING ━━━
+
+### A variable is empty on one node but set on another
+
+The template entry is missing. Confirm:
+
+```bash
+grep -n "MY_VARIABLE" Deployment/master.conf.template Deployment/host.conf.template
+```
+
+No hit means the variable was added to a conf directly and never to the template, so it has
+never reached any other node. Add it to the template; the next pull propagates it.
+
+### `conf_upgrade` reports a key as REMOVED that is still in use
+
+Same cause, opposite direction — the key is in your conf and in a script, but not in the
+template. Add it to the template before the next pull drops it.
+
+### The conf came back with different permissions
+
+It should not — the target's mode and owner are copied onto the staged file before the
+rename. If they did change, check that the target existed before the run: `chmod --reference`
+silently no-ops against a missing file.
+
+### A conf edit disappeared after a pull
+
+Expected if the key is not in the template. `conf_upgrade` keeps values for keys that exist in
+both; a key present only in your conf is classified REMOVED and dropped. Add it to the

+
+The schema layer. `Configurations/*.conf` holds every value the ecosystem runs on — and is
+gitignored, because it holds credentials. This folder holds the **templates** those confs are
+built from, and the two scripts that keep the confs in step with them.
+
+Two files that are versioned, and two scripts that reconcile the unversioned confs against
+them:
+
+```
+  Deployment/master.conf.template     349 vars   ← the versioned schema
+  Deployment/host.conf.template       140 vars   ← per-host schema, HOSTN_-prefixed
+  Deployment/conf_upgrade.sh                     ← template → conf, values preserved
+  Deployment/conf_populate.sh                    ← running services → conf, empty fields only
+```
+
+> **The templates are the only versioned record of what configuration exists.** Nothing else
+> in git knows that a variable is supposed to be there.
+
+---
+
+## ━━━ THE PROBLEM THAT BUILT THIS ━━━
+
+**Config Holds Secrets, So Config Cannot Be Committed**
+`master.conf` and `host*.conf` contain API keys, passwords, SSH key paths and personal
+hostnames. They are gitignored, along with their `.bak` files:
+
+```
+.gitignore:4   Configurations/host*.conf
+.gitignore:5   Configurations/master.conf
+.gitignore:6   Configurations/*.bak
+```
+
+That is correct and non-negotiable. But it creates a problem: if the confs are not in git,
+then **git has no idea a new setting was ever added.** A script that starts reading
+`NEW_THRESHOLD` works on the machine where it was developed and silently fails everywhere
+else, because no other node's conf has that key.
+
+**A New Node Would Start With Nothing**
+Without a versioned schema there is no way to stand up a second server, or rebuild a wiped
+one, except by hand-copying a conf from a machine that already works — which means copying
+its credentials too.
+
+**Hand-Editing Confs Across Nodes Does Not Scale**
+Two servers, ~490 variables between them. Adding a setting by hand means editing it on every
+node, in the right section, with the right default, without disturbing the values already
+there. Miss one and the failure surfaces days later as a script behaving differently on one
+host.
+
+---
+
+## ━━━ WHAT THIS FOLDER DOES ━━━
+
+### 🔀  Schema Merge — `conf_upgrade.sh`
+
+Merges a template into an existing conf while preserving **every value the user has already
+set**. Runs automatically from `git_pull_execute.sh` after every single pull.
+
+```
+  Key in template only  →  ADDED     placeholder/default, filled in once
+  Key in conf only      →  REMOVED   deprecated in this version
+  Key in both           →  KEPT      the conf's value always wins
+  Comments, blank lines →  from the template — structure follows the new version
+```
+
+That last rule is what makes it safe to run unattended forever: the template supplies
+*structure and new keys*, never settings. Your values cannot be overwritten by a pull.
+
+The live confs currently match their templates exactly — 349 and 140 variables — which is
+what a working merge looks like.
+
+### 🔎  Credential Discovery — `conf_populate.sh`
+
+Reads settings out of the services actually running on this host and writes them into the
+host conf: arr API keys from each `config.xml`, ports from real docker port bindings, paths
+from real volume mounts, SABnzbd/slskd/qBittorrent credentials from their own config files.
+
+Only fills **empty** fields unless `--overwrite`. Manual — it is not scheduled anywhere.
+
+---
+
+## ━━━ HOW A CHANGE REACHES EVERY NODE ━━━
+
+```
+You add a variable
+    │
+    └── edit Deployment/master.conf.template   ← the versioned schema
+            │
+            git push
+            │
+            └── every node: git_pull_execute.sh
+                    │
+                    └── conf_upgrade.sh --template ... --target ... --backup
+                            │
+                            ADDED   → new key appears with the template default
+                            KEPT    → every existing value untouched
+                            REMOVED → deprecated keys dropped
+```
+
+**This is the rule that follows from it, and it is not optional:**
+
+> Any conf variable change — add, remove, or rename — must update
+> `Deployment/master.conf.template` and `Deployment/host.conf.template` **in the same pass**
+> as the script change that uses it.
+
+A script merged without its template entry works only on the machine it was written on.
+Nothing errors; the variable is simply empty everywhere else, and the script takes whatever
+branch an empty value leads to.
+
+---
+
+## ━━━ THE `HOSTN_` PLACEHOLDER ━━━
+
+`host.conf.template` is written with a generic prefix — 149 occurrences of `HOSTN_`:
+
+```bash
+HOSTN_SONARR_URL=""
+HOSTN_SONARR_API_KEY=""
+```
+
+`git_pull_execute.sh` substitutes the real identity before merging, so keys match the target:
+
+```bash
+sed "s/HOSTN_/${MY_ID}_/g; s/REMOTE_ID/${REMOTE_ID}/g" host.conf.template > "$TMPL_RESOLVED"
+```
+
+One template therefore serves every host. HOST1 merges it as `HOST1_*`, HOST2 as `HOST2_*`,
+and a third node would work with no template change at all.
+
+---
+
+## ━━━ SCRIPTS IN THIS FOLDER ━━━
+
+| Script | Role | When It Runs |
+|--------|------|-------------|
+| `conf_upgrade.sh` | Merge template into conf — structure forward, values preserved | Automatically, after every `git pull` |
+| `conf_populate.sh` | Detect settings from running services into the host conf | Manually — onboarding, or after a key rotation |
+| `migrate_data_layout.sh` | Move everything persisted into the rooted `data/` tree | Once per host, manually. Idempotent. |
+
+### 📦  Data layout migration — `migrate_data_layout.sh`
+
+`conf_upgrade.sh` adds keys the template has and the installation does not; it never rewrites a
+value you already have. That is exactly what you want from it, and exactly why it cannot perform
+a layout migration — the paths being moved are *existing* keys, so their values would keep
+pointing at the old layout forever while the new directory variables sat beside them unused.
+
+So this rewrites those values and moves the files to match. Both halves or neither.
+
+```bash
+Deployment/migrate_data_layout.sh --dry-run    # always first
+Deployment/migrate_data_layout.sh
+```
+
+It refuses to run while a job from *this* installation is active — scoped to the installation's
+own path, because `pgrep` is system-wide and a box running both a production checkout and a
+development clone will otherwise always look busy. `--force` overrides.
+
+Each host runs it itself: `data/` is gitignored, so a restructure travels as code and conf while
+the files stay where they are. See `data/README.md` for the resulting layout.
+
+| Template | Role |
+|----------|------|
+| `master.conf.template` | Shared schema — thresholds, toggles, profiles, orchestrator job lists |
+| `host.conf.template` | Per-host schema — credentials, paths, container names. `HOSTN_`-prefixed |
+
+---
+
+## ━━━ SAFEGUARDS WORTH KNOWING ━━━
+
+**The install is atomic.** `conf_upgrade.sh` stages the merged conf beside the target and
+installs it with a rename, never a copy. A `cp` truncates the live conf and writes into it —
+and every watchdog sources `load_config.sh` on every run, so anything reading during that
+window would get a partial conf with empty path variables. The temp file is staged in the
+target's own directory deliberately: `/tmp` is rootfs while the confs are on flash, and a
+cross-device `mv` degrades to copy-then-unlink, which is the exact torn write being avoided.
+
+**Dry run needs no privilege, writing does.** `--dry-run` prints the full ADDED / REMOVED /
+KEPT report and is useful to anyone. Installing over a conf under `/boot` requires root.
+
+**`conf_upgrade.sh` sources nothing — deliberately.** No `load_config.sh`, no `common.sh`.
+It is the tool that repairs the conf `load_config.sh` depends on, so it has to work when that
+conf is broken, partial, or missing keys. That is also why it uses plain `echo` rather than
+`log()`, and why it has no `acquire_lock` — concurrency is handled by the atomic rename
+instead, and since the merge is idempotent, last-writer-wins is identical to running once.
+
+**`conf_populate.sh` refuses to guess a container.** An ambiguous name prefix skips the field
+rather than picking the first match. Writing the wrong container name is worse than writing
+nothing: an empty field is visibly incomplete and gets fixed, a wrong one silently points the
+whole stack at the wrong instance. This host has a live example — `authelia` prefix-matches
+both `Authelia` (9091) and `Authelia-Secondary` (9092).
+
+---
+
+## ━━━ THE RECOVERY GAP ━━━
+
+Confs are gitignored, **and so are their `.bak` files**. There is no versioned history to
+revert to, and the single `.bak` slot is overwritten by whoever writes next:
+
+| file | modified | its `.bak` |
+|---|---|---|
+| `master.conf` | Jul 28 18:52 | Jul 28 18:52 |
+| `host1.conf` | Aug 1 21:00 | **Jul 3 17:46** |
+
+A bad write to `master.conf` currently falls back to a file that may predate weeks of edits.
+Worth knowing before hand-editing a conf, and the reason `--backup` exists on `conf_upgrade.sh`
+at all.
+
+Moving `Configurations/` into a private repo would make `git diff` and `git revert` the
+recovery mechanism and give the history for free. That overlaps the existing GitHub-mirror
+TODO, which is blocked on the same question — see `Notes_AI-Design.md`, where it also blocks
+AI-assisted conf writes.

+#   thoroughly as not substituting at all. Without the flag, a template containing HOSTN is
+#   refused exactly as before.

+# A Target Owning Two Slots Is Refused

+# Total Mismatch Is Refused
+#   Keeping nothing from a populated conf is never a real upgrade; it means the two files do
+#   not describe the same thing. KEPT 0 with a non-empty REMOVED list aborts. This is the

+# ============================== DATA LAYOUT MIGRATION =========================================
+# ==============================================================================================
+#
+# PURPOSE
+# ─────────────────────────────────────────────────────────────────────────────
+# One-time move of everything Varaverk persists into a single rooted tree under DATA_DIR.
+#
+#   State_Files/              →  data/state/
+#   data/*.db|.count|.tsv|.list → data/db/
+#   data/ai_*                 →  data/ai/
+#   data/*_tracked_cache.json →  data/cache/arr/
+#   data/*.log                →  data/logs/
+#   SCRIPTS_DIR/.cache/vv/d/  →  data/cache/conf/
+#
+# ==============================================================================================
+# WHY THIS EXISTS SEPARATELY FROM conf_upgrade
+# ==============================================================================================
+#
+# conf_upgrade adds keys the template has and the installation does not; it never rewrites a
+# value the operator already has, which is exactly the behaviour you want from it and exactly
+# why it cannot perform this migration. The paths being moved are existing keys — STATE_DIR,
+# BANDWIDTH_LOG, AI_INDEX_DB and two dozen more — so their values would keep pointing at the old
+# layout forever while the new directory variables sat beside them unused.
+#
+# So this rewrites those values, then moves the files to match. Both halves, or neither: a conf
+# pointing at a directory the data is not in is worse than not having started.
+#
+# ==============================================================================================
+# OPERATIONAL MODEL
+# ==============================================================================================
+#
+# Two halves, in order: move the files, then rewrite the conf keys that point at them. Doing it
+# the other way round would leave every path variable naming a location nothing had reached yet,
+# and any script that ran in between would create the old layout again underneath the new one.
+#
+# Idempotent. A path already under DATA_DIR is left alone, so a re-run after a partial migration
+# finishes the job rather than moving things twice or failing on what is already done.
+#
+# One-time by intent, not by a marker file. There is no "already migrated" flag — the check is
+# whether each individual path is already where it belongs, which is also what makes an
+# interrupted run safe to repeat.
+#
+# ==============================================================================================
+# DESIGN PRINCIPLES
+# ==============================================================================================
+#
+# Existing keys are rewritten, which is why conf_upgrade cannot do this.
+#   conf_upgrade adds keys the template has and the installation does not, and never rewrites a
+#   value the operator already holds — correct for it, and exactly why it is the wrong tool here.
+#   STATE_DIR, BANDWIDTH_LOG, AI_INDEX_DB and two dozen more are existing keys whose values must
+#   change, or they would go on naming the old layout forever while the new directory variables
+#   sat beside them unused.
+#
+# Move, never copy-and-hope.
+#   The data being relocated is the only copy — statistics, histories, the AI index, arr caches.
+#   Everything is moved and the source is gone afterwards, so there is no second location that
+#   might still be written to by something that missed the change.
+#
+# The conf rewrite is the last thing, and the riskiest thing.
+#   Until it happens the installation still works from the old layout. That ordering means an
+#   abort partway through leaves a system that runs, rather than one whose paths point at
+#   nothing.
+#
+# ==============================================================================================
+# OPERATIONAL SAFEGUARDS
+# ==============================================================================================
+#
+# Idempotent
+#   Every step tests before acting. A second run reports "already migrated" and changes nothing,
+#   which matters because the natural instinct after a partial failure is to run it again.
+#
+# Moves, never copies-and-deletes
+#   mv within one filesystem is atomic per file, so a reader either sees the file at the old
+#   path or the new one — never a half-written copy at both. Nothing is deleted; if a file
+#   cannot be moved it is reported and left exactly where it is.
+#
+# Conf is backed up before it is rewritten
+#   master.conf.bak-<stamp>, next to the original, same convention conf_upgrade uses.
+#
+# Refuses to run while the orchestrators might be writing
+#   A watchdog that sourced conf before the rewrite and writes state after the move would put a
+#   file back at the old path. The window is seconds and the damage is one stale file, but the
+#   check costs nothing and the failure is silent otherwise.
+#
+# ==============================================================================================
+# CONFIGURATION
+# ==============================================================================================
+#
+# This script reads conf to find the old locations and rewrites conf to record the new ones. It
+# is the one script here whose purpose is to change these values rather than obey them.
+#
+#   Read to locate what moves
+#     STATE_DIR, BANDWIDTH_LOG, AI_INDEX_DB, AI_MEMORY_FILE, AI_TOKEN_DB, ARR_CLEANUP_STATS,
+#     ARR_SYNC_BLOCKLIST, CORRUPTION_SCAN_STATE_FILE, LIDARR_CACHE_FILE, ZFS_REPORT_LOG and the
+#     rest of the per-script path keys — roughly two dozen in total.
+#
+#   Written as the new roots
+#     DATA_DIR and the directories beneath it: DB_DIR, STATE_DIR, AI_DATA_DIR,
+#     CACHE_BACKUP_DIR, ARR_CACHE_BACKUP_DIR, CONF_CACHE_BACKUP_DIR, LOG_ARCHIVE_DIR.
+#
+#   Every rewritten value is expressed as ${DB_DIR}/… rather than an absolute path, so a later
+#   storage-mode migration moves them again by changing one variable.
+#

-`docker_update.sh` in normal mode targets `DAILY_RESTART_CONTAINERS` — the same list
-used by `docker_daily_restart.sh`. No second list to maintain.
+There is one update script, `docker_update.sh`, with three modes. Each reuses the restart
+list it pairs with, so there is no second list to maintain:
 
-`docker_update_remaining.sh` derives its target list automatically:
-all running containers minus `DAILY_RESTART_CONTAINERS` minus `WEEKLY_RESTART_CONTAINERS`.
-Everything gets updated at least once per week with no explicit configuration.
+| Mode | Targets | Runs |
+|------|---------|------|
+| *(default)* | `DAILY_RESTART_CONTAINERS` | Daily, before `docker_daily_restart.sh` |
+| `--weekly` | `WEEKLY_RESTART_CONTAINERS` | Weekly, before `docker_weekly_restart.sh` |
+| `--remainder` | derived, see below | Monthly, via `MONTHLY_MAINTENANCE_SCRIPTS` |
+
+Remainder mode needs no configuration at all. It takes every **running** container and
+subtracts:
+
+```
+  DAILY_RESTART_CONTAINERS                          already updated daily
+  WEEKLY_RESTART_CONTAINERS                         already updated weekly
+  PROFILE_CRITICAL_CONTAINER_NAMES[emby]            updated inline by the weekly sync window
+  PROFILE_CRITICAL_CONTAINER_NAMES[critical-data]   updated inline by the weekly sync window
+  FALLBACK_<REMOTE>_TIER1..4                        owned by the remote's update cycle
+```
+
+Stopped containers are never targeted in any mode — pulling for a stopped container adds
+nothing, and it was most likely stopped deliberately.
+
+The fallback exclusion is a correctness rule, not an optimisation. This server only runs
+those containers during a fallback; the remote owns their version. If remainder updated them
+independently and a handback then occurred, the remote's older image could meet data written
+by the newer one.
+
+**Ordering matters.** The update always runs *before* its matching restart so the restart
+lands on the freshly pulled image. If a container's image actually changed, `docker_update.sh`
+rebuilds it from its template (a plain `docker restart` reuses the image ID baked in at
+creation time and would never pick up the new digest) and records it in
+`DOCKER_UPDATE_REBUILT_*_FILE`. The restart script reads that file and skips those containers
+rather than restarting them a second time — and discards the file as stale if it is older
+than `DOCKER_UPDATE_REBUILT_STALE_HOURS`.

+## ━━━ SAFEGUARDS COMMON TO THIS FOLDER ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+
+Every script here talks to the Docker daemon, so they share the same protections. Each
+script's own header documents its full set; these are the ones worth knowing folder-wide.
+
+**Daemon health is checked, not assumed.** A hung daemon returns an empty container list,
+which is indistinguishable from "no containers running". Without the check,
+`docker_container_stop.sh` would report a clean shutdown that never happened, and
+`docker_update.sh --remainder` would report "nothing to update" while doing nothing.
+
+**Every docker call is timeout-wrapped.** A wedged daemon cannot stall a maintenance window
+or hold a lock open. The one deliberate exception is `docker pull` — a large image
+legitimately outlasts any sane timeout, and killing it mid-layer wastes the transfer.
+
+**State is respected.** Running containers get restarted; stopped ones stay stopped. A
+stopped container was almost certainly stopped on purpose, and none of these scripts has the
+authority to overrule that.
+
+**Restarts are verified, not assumed.** After each restart the container is re-checked once
+it has had time to settle. A container that starts and immediately crashes is recorded as a
+failure and notified — a restart that did not stick is never reported as success.
+
+**Dependency ordering is shared with the watchdog.** Restarts follow
+`HOST*_WATCHDOG_DEPENDENCIES`, with `CONTAINER_DELAY` between a dependency and its dependents,
+so a dependent is never brought up while what it needs is still initialising.
+
+**Locks prevent overlap.** Long windows can outlast their interval;
+`downloaders_reset.sh` uses wait-mode because it runs every 30 minutes and the previous pass
+may still be finishing.

+# Weekly Cadence

+# State Respect
+#   Running containers are restarted. Stopped containers are left stopped — they
+#   were intentionally halted and this script has no authority to override that
+#   decision. This rule is consistent across the entire ecosystem.
+#
+# Dependency-Safe Ordering

-Variable pattern: `FALLBACK_${MY_ID}_COVERS_${REMOTE_ID}_TIER${N}`
+**Each host declares its OWN services, in its OWN conf.** `FALLBACK_HOST2_TIER1` lives in
+`host2.conf` and lists HOST2's vital containers — it is not a list HOST1 maintains.
 
-The DDNS container for the remote's domain must be the first entry in TIER1 — DNS
-coverage before anything else.
+At runtime `fallback.sh` reads its **partner's** list:
+
+```bash
+get_tier_containers() {
+    local var_name="FALLBACK_${REMOTE_ID}_TIER${tier}"     # note: REMOTE_ID, not MY_ID
+```
+
+So HOST1, covering HOST2, reads `FALLBACK_HOST2_TIER1` — a variable defined in `host2.conf`
+and delivered to HOST1 through the partner conf cache (`conf_sync.sh`), because sparse
+checkout means HOST1 never pulls `host2.conf` from git.
+
+This is why the naming is what it is. The alternative — each host keeping a copy of its
+partner's container list — would need editing on both machines every time either one changed
+a service, and the two copies would silently diverge. Declaring once, on the host that owns
+the services, means a host is always the authority on what covering it requires.
+
+TIER1 starts immediately. TIER2–4 activate after their delay thresholds
+(`HOST*_TIER2_DELAY` and friends, also in that host's own conf).
+
+The DDNS container for that host's domain must be the **first entry in TIER1** — DNS coverage
+before anything else.

+# ══════════════════════════════════════════════════════════════════════════════════════════════
+# PURPOSE
+#   Put the containers this host has marked for fallback coverage onto the partner, so that the
+#   partner can actually start them during an outage — and take them off again on request.
+#
+# OPERATIONAL MODEL
+#   fallback.sh covers a host by running `docker start <name>` on the partner. It never creates
+#   anything. So a name in FALLBACK_<me>_TIER* is a promise that only holds if the partner already
+#   has that container built. Measured 2026-08-23: all 12 of HOST1's covered containers were absent
+#   from HOST2, meaning every tier would have failed on the first real outage while the UI showed
+#   coverage as configured. This script is what closes that gap.
+#
+#   Push and remove are separate, deliberate actions, never a side effect of saving the tier list.
+#   Editing coverage is a cheap config write; deploying a dozen containers onto another machine is
+#   not, and the two should not share a button.
+#
+# DESIGN PRINCIPLES
+#   Deployed, then verified STOPPED.
+#       A container built here and left running on the partner would be a second live instance of
+#       NextCloud, Gitea or PostgreSQL_Immich against the same data while this host is healthy.
+#       That is the danger_rsync_live_database_appdata failure with worse odds. Every deploy is
+#       followed by a stop and a re-inspect, and a container that will not stay stopped is an
+#       error, not a warning.
+#
+#   Remove takes the container AND its appdata.
+#       Operator decision 2026-08-23: the button is explicit, so a removal should leave nothing
+#       behind to reason about later. The risk it accepts is narrow and worth naming — if the
+#       partner ever covered for us, ITS appdata is the newer copy and is what a handback rsyncs
+#       home. The NORMAL-state gate below closes the live-failover window; what it cannot see is
+#       a handback that partially failed and then returned to NORMAL, so the UI says so before
+#       asking.
+#
+#       Two guards on the deletion itself: only paths under /mnt/*/appdata* are ever touched, and
+#       a bind of the appdata ROOT is refused outright — a container mounting /mnt/user/appdata
+#       would otherwise turn one removal into wiping every application on the partner.
+#
+#   Refuses to run unless fallback state is NORMAL.
+#       Pushing or removing containers mid-outage edits the thing currently keeping services up.
+#
+#   Coverage names are resolved to templates by <Name>, not by filename.
+#       my-Foo.xml routinely holds a container called something else. Matching on the filename
+#       silently pushes the wrong template, or nothing at all.
+#
+# OPERATIONAL SAFEGUARDS
+#   Only in NORMAL state. FALLBACK_STATE_FILE is read before anything is pushed or removed, and
+#   any other state refuses the action. A push during a live failover would deploy a second copy
+#   of a container the partner is currently running on our behalf; a remove would delete the one
+#   doing the covering.
+#
+#   --status is exempt from that gate, because it only reports. Refusing to answer "what is
+#   deployed over there" during a failover would withhold the information precisely when it is
+#   most wanted.
+#
+#   Every deploy is verified stopped, and a container that will not stay stopped is an error
+#   rather than a warning — see DESIGN PRINCIPLES. A second live instance against the same data
+#   is the failure this whole script exists inside.
+#
+#   Push and remove are explicit modes with no default. Running the script with no flag does
+#   nothing; neither action can be reached by accident, and neither is a side effect of editing
+#   the tier list.
+#
+#   --dry-run works in every mode and touches nothing on either host — no container is built,
+#   started, stopped or removed, and no template is written or deleted.
+#
+#   Remove deletes the container's appdata on the partner as well. That is deliberate and is the
+#   most destructive thing here; the NORMAL-state gate above is what keeps it away from a
+#   partner that is mid-handback.
+#
+# CONFIGURATION
+#   master.conf
+#     FALLBACK_<HOST>_TIER1..N   the covered container names — what --push deploys and --status
+#                                reports on. This script reads that list; it never edits it.
+#
+#   host*.conf
+#     FALLBACK_STATE_FILE        overrides where fallback.sh's state is read from. Defaults to
+#                                STATE_DIR/fallback_state.db. A missing file reads as NORMAL,
+#                                which is the correct default on a host where fallback has never
+#                                run.
+#
+# RUNTIME MODES

+Scripts live in `/boot/config/plugins/user.scripts/Varaverk/Scripts/` — deliberately

+place the Unraid User Scripts plugin keeps its own scripts, so it's a folder location
+admins are already used to.
+
+Two ways to get a script there:
+
+- Click **+ Create Script** on the Scheduler tab — opens an inline editor, writes the
+  file to that folder, and adds a `schedule.json` entry automatically.
+- Drop any `.sh` file into the folder yourself (e.g. via terminal, or Unraid's own
+  Custom Scripts / User Scripts plugin pointed at the same path). The Scheduler tab

-## ━━━ ARR CLEANUP — FILE CLASSIFICATION ━━━
-
-Every file found on disk during an arr cleanup run falls into exactly one category:
-
-```
-TRACKED    → arr API returned this exact path                   → leave it alone
-PROTECTED  → matches ARR_PROTECTED_PATTERNS                     → never delete
-ORPHAN     → media extension, not tracked, old enough           → delete
-JUNK       → not a media extension, not protected               → delete (any age)
-RECENT     → not tracked, under ARR_ORPHAN_AGE days             → skip (may be mid-import)
-```
-
-**Why protected patterns are critical:** arrs generate artwork (`*.jpg`), metadata
-(`*.nfo`), and subtitles/lyrics that do NOT appear in the tracked file API response.
-Without protection, these would be classified as orphans and deleted — removing cover art
-from every album, every movie poster, every TV show thumbnail. Requires a full rescan
-to recover. Never remove artwork extensions from protected patterns.

-## ━━━ ARR CLEANUP — SAFETY LAYERS ━━━

-
-```
-1. Container running + healthy      — a stopped container has an empty API
-2. API reachable                    — no API = no tracked file list = everything looks orphaned
-3. API version matches              — major version must match tested version in master.conf
-4. Item count > 0                   — no artists/series/movies = something is wrong with DB
-5. Tracked file count > 0           — empty response = everything would be deleted
-6. Tracked count >= MIN_TRACKED_PCT — dramatic drop from last run = abort and alert
-7. Deletion size < MAX_DELETE_GB    — last line of defense against misconfigured root path
-```
-
-Layer 7 is the catastrophic failure prevention. A misconfigured root path — pointing
-cleanup at the wrong directory — means the API returns zero tracked files for a root
-that actually contains thousands. Everything walks as an orphan. Everything gets deleted.

-> the arr's own settings.** Arr UI → Settings → Media Management → Root Folders.
-> A mismatch means every file on disk looks untracked — all appear as orphans.
-> MAX_DELETE_GB is the only thing standing between a path mismatch and losing your library.
-
----
-
-## ━━━ SAFE TESTING PROCEDURE ━━━
-
-> **The arr cleanup scripts permanently delete files.** There is no recycle bin, no undo.
-> Follow this procedure on first use, after any root path change, after any API key change,
-> and after any significant arr library change.
-
-### Step 1 — Dry Run With Full Logging
-
-```bash
-lidarr_cleanup.sh --dry-run --log
-sonarr_cleanup.sh --dry-run --log
-radarr_cleanup.sh --dry-run --log
-```
-
-### Step 2 — Review the Output
-
-```
-Are TRACKED files the ones you expect?
-  → Known arr-managed files should show as TRACKED
-  → If they show as ORPHAN, the root path is wrong — STOP
-
-Is the ORPHAN count reasonable?
-  → Healthy cleanup removes dozens to hundreds, not tens of thousands
-  → Large count = stop, investigate root path before proceeding
-
-Are PROTECTED patterns working?
-  → Artwork (*.jpg) and subtitles (*.srt) must show as PROTECTED
-  → If they show as ORPHAN, check PROTECTED_PATTERNS config
-
-Are RECENT files being correctly skipped?
-  → Files downloaded in the last 7 days should show as RECENT, not ORPHAN
-```
-
-### Step 3 — Check Numbers if Something Looks Wrong
-
-```bash
-# Root path mismatch? Compare these:
-# Lidarr UI: Settings → Media Management → Root Folders
-# Sonarr UI: Settings → Media Management → Root Folders
-# Radarr UI: Settings → Media Management → Root Folders
-# Must exactly match LIDARR_MUSIC_ROOT / SONARR_TV_ROOT / RADARR_MOVIES_ROOT
-
-# Is the arr running?
-docker ps | grep -E "Lidarr|Sonarr|Radarr"
-
-# Library scan not complete?
-# Trigger manual scan in arr UI and wait for completion
-```
-
-### Step 4 — Run Live
-
-```bash
-# Only after dry run review passes.
-lidarr_cleanup.sh
-sonarr_cleanup.sh
-radarr_cleanup.sh
-```
-
-### Step 5 — Verify in Arr UI
-
-```
-Library count  — should not have dropped significantly
-                 healthy cleanup removes a small number, not a large percentage
-Missing files  — check if any monitored content shows as missing
-Emby library   — should show no ghost entries (notify_emby_scan handles this automatically)
-```

-
-### Adding a New Arr
-
-```bash
-# 1. Copy radarr_cleanup.sh as template
-cp radarr_cleanup.sh readarr_cleanup.sh
-
-# 2. Replace RADARR_ prefix with READARR_ throughout
-#    Update API endpoint, tracked file API path, extension list, protected patterns
-
-# 3. Add to host*.conf
-HOST1_READARR_URL="http://192.168.50.2:8787"
-HOST1_READARR_API_KEY="your-api-key"
-HOST1_READARR_BOOKS_ROOT="/mnt/user/Books"

-READARR_EXTENSIONS=("epub" "pdf" "mobi" "azw3" "cbz" "cbr")
-READARR_PROTECTED_PATTERNS=("*.jpg" "*.jpeg" "*.png" "*.nfo")

-### Managing the Arr Sync Blocklist
-
-```bash
-# Add item to blocklist (removes from all arrs + tombstones the ID)
-arr_sync.sh --blocklist-add lidarr <musicbrainz-artist-id> "reason"
-arr_sync.sh --blocklist-add sonarr <tvdb-series-id> "reason"
-arr_sync.sh --blocklist-add radarr <tmdb-movie-id> "reason"
-
-# Remove from blocklist (un-tombstones the ID — does NOT re-add to arrs)
-arr_sync.sh --blocklist-remove lidarr <id>
-
-# View all blocklisted IDs
-arr_sync.sh --blocklist-list
-```
-
-`--blocklist-add` is the only destructive operation — it simultaneously:
-1. Writes the tombstone entry to the blocklist TSV file
-2. Deletes the item from the local arr API (no file deletion)
-3. SSHes each remote node and deletes from their arr API
-
-Files become orphans on all nodes — arr_cleanup removes them on the next run.
-
----
-
-## ━━━ TROUBLESHOOTING ━━━
-
-### Arr Cleanup Deleting Files It Shouldn't
-
-```
-1. Check the protected patterns — artwork and subtitles must be listed
-   LIDARR_PROTECTED_PATTERNS / SONARR_PROTECTED_PATTERNS / RADARR_PROTECTED_PATTERNS
-
-2. Check the root path matches arr settings exactly
-   Run: lidarr_cleanup.sh --status   (shows configured root path)
-   Compare: Lidarr UI → Settings → Media Management → Root Folders
-
-3. Check if files are truly orphaned
-   Run: lidarr_cleanup.sh --dry-run --log
-   Look for the specific file — verify it shows ORPHAN, not PROTECTED or TRACKED
-```
-
-### Arr Cleanup Aborting at Safety Layer 6 (Tracked Count Drop)
-
-```
-API returned far fewer tracked files than last run.
-Possible causes:
-  - Arr database was recently rebuilt from scratch
-  - Large manual library removal
-  - Path map mismatch after arr migration
-
-If intentional (library intentionally reduced):
-  Delete LIDARR_TRACKED_COUNT_FILE to reset the baseline
-  Run cleanup once — it will establish a new baseline
-
-If unintentional:
-  Investigate before proceeding — the arr may have a problem
-```
-
-### Arr Sync Not Picking Up New Content
-
-```
-Is ARR_SYNC_ENABLED=true in master.conf?
-
-Can this host SSH to the remote without password?
-  → ssh -i [SSH_KEY] root@[remote-tailscale-ip] "hostname"
-
-Is the arr accessible on the remote?
-  → arr_sync.sh --status  (shows each node's arr reachability)
-  → arr_sync.sh --log     (verbose output per-node, per-arr)
-
-Is the item in the blocklist?
-  → arr_sync.sh --blocklist-list
-```
-
-### Emby Still Showing Ghost Entries After Cleanup
-
-```
-notify_emby_scan() is called automatically after every arr cleanup deletion.
-If ghosts persist:
-  1. Is Emby's API responding?
-     curl -s "http://[emby-ip]:8096/System/Info/Public"
-
-  2. Is EMBY_URL / EMBY_API_KEY correct in host*.conf?
-     Run: sonarr_cleanup.sh --status  (shows Emby config)
-
-  3. Trigger manually in Emby:
-     Library → Manage Library → Clean Missing Files

+**Files Owned by Root That Arrs Can't Touch**
 Download clients without explicit PUID/PGID write files owned by root. Arrs running as
 `nobody:users` cannot rename, move, or delete them. Import fails. Upgrade attempts fail.
 The failure is subtle — arr shows the file as managed but can't touch it. You only
-discover this when an upgrade is requested and the old version refuses to delete.  
+discover this when an upgrade is requested and the old version refuses to delete.

-**Scene Junk Confusing Orphan Detection**  
+**Scene Junk Confusing Orphan Detection**
 Scene releases include `.sfv`, `.nfo`, `.rar`, `.sample` files alongside the actual media.
 After extraction and import these are worthless — but they're not tracked by any arr.
 They look like orphans. Processing them as orphans means the cleanup output is full of
-noise, making it hard to spot actual orphaned media.  
+noise, making it hard to spot actual orphaned media.
 The fix: `media_cleaner.sh` runs before any arr cleanup and removes all known junk
 patterns first. By the time arr cleanup runs, every untracked file is actual media.
 
-**Deleted Shows and Removed Albums Still on Disk**  
-When you remove a series from Sonarr and the delete command fails — permission issue,
-container wasn't running, path mismatch — the files stay permanently. Over years on an
-active library this accumulates significantly.  
-The fix: arr cleanup scripts query the live API for every tracked file path, walk the
-disk, and delete anything absent from the API response that's old enough to be past the
-import window.
-
-**Emby Showing Ghost Entries After Cleanup**  
-After arr cleanup deletes files, Emby still shows them until its next scheduled scan —
-potentially hours later. Users see broken entries that produce "file not found" errors.  
-The fix: `notify_emby_scan()` is called automatically after every deletion. Triggers
-Emby's "Clean Missing Files" task immediately.
-
-**No Safety Net on Deletion Size**  
-A misconfigured root path — pointing cleanup at the wrong directory — means the API
-returns zero tracked files for a root that actually contains thousands. Every file walks
-as an orphan. Everything gets deleted. This is the catastrophic failure mode.  
-The fix: `LIDARR/SONARR/RADARR_MAX_DELETE_GB` — if total deletion size exceeds the
-limit, the script stops and requires `--i-know-what-im-doing` to proceed. The flag name
-is long and annoying by design. It cannot be added by accident.
+**Watch State Diverging Across Servers**
+With two Emby servers, played status and resume positions diverge — a film marked watched
+on HOST1 shows as unwatched on HOST2. Two users on different servers get different
+continue-watching rows.
+The fix: `play_state_sync.sh` syncs watched/played state and resume positions every 30
+minutes. Newest timestamp wins. Both servers always reflect the same play history.

 ## ━━━ WHAT THIS FOLDER DOES ━━━
 
-Scripts divide into five functional areas:
-
-**Library Foundation**  
+**Library Foundation**
 `media_shares_permissions.sh` — normalize ownership and permissions daily. Runs first in
 every maintenance window because arr cleanup depends on correct ownership to delete files.
 
-**Junk Removal**  
+**Junk Removal**
 `media_cleaner.sh` — remove scene debris and tool artifacts before orphan scan. Runs
-second, before any arr cleanup, so orphan detection only encounters actual media files.
+before any arr cleanup so orphan detection only encounters actual media files.
 
-**Library Sync**  
-`arr_sync.sh` — full-mesh arr library sync across all nodes. Every node syncs with every
-other — union model, no hierarchy. Once arrs agree on what to track, rsync spreads the
-actual files. The architectural shift from file-first sync to arr-first sync.
-
-**Orphan Cleanup**  
-`lidarr_cleanup.sh`, `sonarr_cleanup.sh`, `radarr_cleanup.sh` — API-verified orphan
-removal. Five classification categories (TRACKED/PROTECTED/ORPHAN/JUNK/RECENT), seven
-safety layers, automatic Emby notification after deletion.
-
-**Database Hygiene**  
-`radarr_tmdb_removed.sh`, `sonarr_tvdb_removed.sh` — remove entries that upstream
-databases have dropped (TMDb/TVDB status="deleted"). These generate health warnings in
-arrs and can never be monitored or downloaded. Most are announced-but-never-released
-entries. Files are kept by default — most have none.
-
-**Library Enrichment**  
-`arrs_failed_stalled_recovery.sh` — detect and recover failed imports and stalled
-downloads across all arrs. Blocklists the bad release and triggers a re-search — hands-
-free overnight recovery.  
-`lidarr_missing_art.sh` — fetch missing album and artist artwork from fanart.tv and
-fallback sources. Never overwrites existing files.
-
-**Play State Sync**  
+**Play State Sync**
 `play_state_sync.sh` — syncs watched/played state and resume positions across all
 configured Emby and Jellyfin servers. Newest timestamp wins. Runs every 30 minutes
 via critical_sync_maintenance.sh.
 
-**Upgrade Propagation**  
-`start_webhook_listener.sh` — Node.js HTTP server that receives Sonarr/Radarr/Lidarr
-OnUpgrade webhooks. Continuous; started at array start. Writes to
-`/var/log/varaverk/upgrade_webhook.log`.  
-`upgrade_webhook_handler.sh` — triggered by the webhook listener. Pushes the upgraded
-item folder to every remote node immediately, then triggers an arr library rescan on
-each remote so the upgraded file is accepted without triggering a redundant quality search.
-
-**Discovery**  
-`playback_aware_lidarr_discovery.sh` — behavior-driven music discovery. Scores your
-Emby play history, runs Last.fm getSimilar on top artists, adds the best matches to
-Lidarr. 0–5 meaningful adds per week.  
-`playback_aware_radarr_discovery.sh` — behavior-driven movie discovery. Scores recently
-watched movies, runs TMDB recommendations on seeds, adds top candidates to Radarr.  
-`playback_aware_sonarr_discovery.sh` — behavior-driven TV discovery. Scores recently
-watched series weighted by user diversity, runs TMDB TV recommendations on seeds, adds
-top shows to Sonarr. Multi-user design: one person binge-watching does not dominate seeds.

 Permissions and cleaner scripts run locally against each server's own shares, defined
 in `HOST*_MEDIA_PERMISSION_SHARES` and `HOST*_MEDIA_CLEAN_FOLDERS` in host*.conf.
 
+`play_state_sync.sh` reads both servers' Emby/Jellyfin endpoints from host*.conf and
+syncs between them.

-## ━━━ HOW THE SCRIPTS RELATE ━━━
+## ━━━ THE ctime INVARIANT — READ BEFORE CHANGING PERMISSIONS ━━━
+
+`media_shares_permissions.sh` applies every pass **conditionally** — it touches only entries
+whose owner or mode is actually wrong. That is not an optimisation, and it must stay that way.
+
+`chown` and `chmod` rewrite an inode's ctime **even when the value does not change**. A
+blanket pass would therefore restamp every file in the library every night.
+
+The arr cleanup scripts (`sonarr_cleanup.sh`, `radarr_cleanup.sh`, `lidarr_cleanup.sh`) gate
+orphan deletion on ctime. mtime cannot substitute: an import preserves the release's original
+timestamp, so mtime says nothing about when a file arrived here. Measured 2026-07-27 — of 400
+files imported that week, **all 400 had mtimes over 7 days old, one of them 9613 days.**
+
+So:
 
 ```
-Weekly arr sync (before rsync):
-  arr_sync.sh ──────────────── syncs tracked IDs across all nodes
-        │                      union model: any node adds → all nodes get it
-        │
-        └── then rsync spreads the actual files to all nodes
-        └── then arr_cleanup removes orphans on all nodes (old paths, removed content)
-
-Daily maintenance window (media_management.sh):
-  media_shares_permissions.sh
-        │ (permissions correct — arr can now delete files)
-        ▼
-  media_cleaner.sh (anime + media)
-        │ (junk removed — orphan scan finds only actual media)
-        ▼
-  lidarr_cleanup.sh ──────────── queries Lidarr API → walks /Music → deletes orphans
-  sonarr_cleanup.sh ──────────── queries Sonarr API → walks /Tv_Shows → deletes orphans
-  radarr_cleanup.sh ──────────── queries Radarr API → walks /Movies → deletes orphans
-        │
-        └── each cleanup → notify_emby_scan() → Emby removes ghost entries
-
-Daily recovery:
-  arrs_failed_stalled_recovery.sh ── importFailed/stalled → blocklist → re-search
-
-Weekly discovery (WEEKLY_MAINTENANCE_SCRIPTS):
-  playback_aware_lidarr_discovery.sh ─ Emby plays → Last.fm similar → top candidates → Lidarr
-  playback_aware_radarr_discovery.sh ─ Emby watches → TMDB recommendations → top candidates → Radarr
-  playback_aware_sonarr_discovery.sh ─ Emby episodes → TMDB TV recommendations → top candidates → Sonarr
-        │
-        └── each discovery script fires arr search immediately after successful add
-
-Every 30 min (critical_sync_maintenance.sh CRITICAL_MAINTENANCE_SCRIPTS):
-  play_state_sync.sh ─── newest timestamp wins → watched/resume state synced
-                          across all configured Emby + Jellyfin servers
-
-Continuous (started by array_started.sh):
-  start_webhook_listener.sh ── Node.js HTTP server listens on WEBHOOK_PORT
-        │ arr OnUpgrade fires webhook → POST to http://HOST_LAN_IP:WEBHOOK_PORT/webhook?key=SECRET
-        └── upgrade_webhook_handler.sh
-              ├── rsync upgraded folder → all remote nodes immediately
-              └── trigger arr library rescan on each remote (accept new file, no quality search)
-
-Ad-hoc enrichment:
-  lidarr_missing_art.sh ─────── discovers missing artwork → fetches from fanart.tv
-  radarr_tmdb_removed.sh ────── status="deleted" → remove from Radarr + add exclusion
-  sonarr_tvdb_removed.sh ────── status="deleted" → remove from Sonarr + add exclusion
+  blanket chown/chmod  →  every ctime resets to today
+                       →  no file ever appears older than *_ORPHAN_AGE
+                       →  orphan collection silently stops
+                       →  nothing errors, nothing warns, disk just fills
 ```
+
+**The failure is invisible.** No script fails, no notification fires. The only symptom is
+orphans quietly accumulating until a pool fills — which is exactly how the 755 GB / 89%-full
+cache pool incident happened.
+
+Two rules follow, and both are load-bearing:
+
+1. **`media_shares_permissions.sh` passes stay conditional.** Making any of them unconditional
+   breaks orphan collection ecosystem-wide.
+2. **`Tools/bulk_permissions_repair.sh` is unconditional by design** — it exists to repair
+   known-wrong paths where correctness beats preserving a clock. That is precisely why it is a
+   manual, targeted tool and not scheduled. Pointing it at a whole media root pauses orphan
+   collection there for `*_ORPHAN_AGE` days.
+
+Both scripts' headers carry this warning too. If you are reading this because you are about to
+"simplify" the permissions job, this is the thing that breaks.

-# ==============================================================================================
-# ========================= Arrs Failed / Stalled Recovery =====================================
-# ==============================================================================================
-#
-# PURPOSE
-# ─────────────────────────────────────────────────────────────────────────────
-# Detect and recover failed imports and stalled downloads across Sonarr, Radarr,
-# and Lidarr. Blocklists the bad release and triggers a re-search — hands-free
-# overnight recovery.
-#
-# ==============================================================================================
-# OPERATIONAL MODEL
-# ==============================================================================================
-#
-# Four problem types detected from the arr queue API:
-#   importFailed   — downloaded but arr couldn't import the file
-#   importPending  — downloaded, stuck waiting to import (will not self-resolve)
-#   error status   — serious failure not covered by the above two states
-#   stalled        — download stuck with no connections or no progress
-#
-# Never touches items with state "downloading" or "imported" — safe to run anytime.
-# Items newer than ARR_IMPORT_RECOVERY_AGE are skipped — gives arr time to retry first.
-#
-# Per problem item (3-step response):
-#   1. Blocklist the release  — prevents re-grabbing the same bad release
-#   2. Remove from queue      — cleans up the failed item
-#   3. Trigger new search     — finds a different release automatically
-#
-# ==============================================================================================
-# OPERATIONAL SAFEGUARDS
-# ==============================================================================================
-#
-#   acquire_lock      — prevents concurrent runs overlapping
-#   jq validation     — exits if jq not installed (required for JSON parsing)
-#   API pre-flight    — checks each arr is reachable before querying queue
-#   Version check     — check_arr_version() verifies running arr matches master.conf major
-#                       version; exits rather than silently misoperating after upgrade
-#   Age threshold     — skips items newer than ARR_IMPORT_RECOVERY_AGE (default 6hr)
-#   Silent by default — only problems produce output, clean arrs stay silent
-#
-# API version mapping (endpoint paths differ from major version labels):
-#   Sonarr  v4 → /api/v3/ (v3 endpoint retained in v4)
-#   Radarr  v6 → /api/v3/ (v3 endpoint retained in v6)
-#   Lidarr  v3 → /api/v1/ (different from Sonarr/Radarr)

+# Every pass is conditional by design — see Conditional Passes below.
+#
+# ==============================================================================================
+# DESIGN PRINCIPLES
+# ==============================================================================================
+#
+# Daily Failsafe, Not Enforcer
+#   Wrong ownership is a symptom of something else — a misconfigured container,
+#   a manual copy, an rsync without --chown. This script corrects the symptom
+#   daily rather than hunting the root cause. A persistent high correction count
+#   is the signal to investigate the source.
+#
+# Runs First in the Window
+#   Arr cleanup scripts depend on correct ownership to rename and delete files.
+#   Permissions must be correct before cleanup runs — ordering is not optional.
+#
+# Separate Passes for Directories and Files
+#   Directories need execute permission for traversal; files do not. Applying
+#   the same mode to both is a common mistake this script avoids by design.

+# Folder Existence
+#   Missing shares are skipped with a warning; remaining shares still process.

+# Separate Passes

+#
+# Conditional Passes
+#   Only entries whose owner or mode is actually wrong are touched. This is not
+#   an optimisation: chown/chmod rewrite an inode's ctime even when the value is

-# ==============================================================================================
-# ================================= Radarr Cleanup =============================================
-# ==============================================================================================
-#
-# PURPOSE
-# ─────────────────────────────────────────────────────────────────────────────
-# Delete orphaned movie files not tracked by Radarr. Queries the API for all
-# tracked movie file paths, walks the library on disk, and removes anything
-# untracked that is old enough to be past the import window. Triggers an Emby
-# library clean after each deletion run so ghost entries disappear immediately.
-#
-# ==============================================================================================
-# OPERATIONAL MODEL
-# ==============================================================================================
-#
-# Every file encountered on disk is classified into one of five categories:
-#
-#   TRACKED   — Radarr API knows this exact path → leave it alone
-#   PROTECTED — matches RADARR_PROTECTED_PATTERNS → never delete
-#   ORPHAN    — video file, not tracked, older than RADARR_ORPHAN_AGE → delete
-#   JUNK      — not a video extension, not protected → delete regardless of age
-#   RECENT    — not tracked, under RADARR_ORPHAN_AGE → skip (may be mid-import)
-#
-# Radarr generates movie artwork (*.jpg), metadata (*.nfo), and manages subtitles
-# (*.srt, *.sub, *.ass) but does NOT include these in its tracked file API response.
-# Without PROTECTED classification these would be deleted — breaking Radarr and
-# Emby metadata display.
-#
-# After deletions: notify_emby_scan() triggers Emby "Clean Missing Files" task.
-# Emby removes ghost entries immediately — no user-facing file-not-found errors.
-#
-# ==============================================================================================
-# OPERATIONAL SAFEGUARDS
-# ==============================================================================================
-#
-# Six gates — ALL must pass before any file is touched:
-#   1. Container running and not starting/unhealthy
-#   2. API reachable
-#   3. API version matches RADARR_VERSION_MAJOR in master.conf
-#   4. Movie count > 0
-#   5. Tracked file count > 0
-#   6. Deletion size < RADARR_MAX_DELETE_GB — or --i-know-what-im-doing required
-#
-#   acquire_lock "wait"  — large scans take time, wait for previous run to finish
-#   jq + curl validation — exits if either tool missing
-#   DOCKER_TIMEOUT       — container checks protected against daemon hangs
-#   notify_emby_scan()   — triggers Emby clean after deletion
-#   platform_require_cmd  — notify script validated before use
-#   Silent by default    — orphans/junk warn(), clean library logs silently
-#
-# ==============================================================================================
-# CONFIGURATION
-# ==============================================================================================
-#
-# host*.conf
-#
-#   HOST*_RADARR_URL / HOST*_RADARR_API_KEY / HOST*_RADARR_MOVIES_ROOT
-#   HOST*_RADARR_PATH_MAP — container path → host path translation
-#   All aliased by detect_hosts() — script uses unprefixed names
-#
-# master.conf
-#
-#   RADARR_ORPHAN_AGE          — days before untracked file eligible for deletion
-#   RADARR_MAX_DELETE_GB       — require --i-know-what-im-doing above this
-#   RADARR_EXTENSIONS          — video file extensions for orphan classification
-#   RADARR_PROTECTED_PATTERNS  — file patterns never deleted
-#   RADARR_VERSION_MAJOR       — expected Radarr major version for API safety check
-#   RADARR_IMPORT_SCAN_TIMEOUT — seconds to wait for pre-flight import scan (default 600)
-#   ARR_CLEANUP_STATS          — stats file path (read by coffee report)

-#!/bin/bash
-# ==============================================================================================
-# ================================= Sonarr Cleanup =============================================
-# ==============================================================================================
-#
-# PURPOSE
-# ─────────────────────────────────────────────────────────────────────────────
-# Delete orphaned TV episode files not tracked by Sonarr. Queries the API for
-# all tracked episode file paths, walks the library on disk, and removes anything
-# untracked that is old enough to be past the import window. Triggers an Emby
-# library clean after each deletion run so ghost entries disappear immediately.
-#
-# ==============================================================================================
-# OPERATIONAL MODEL
-# ==============================================================================================
-#
-# Every file encountered on disk is classified into one of five categories:
-#
-#   TRACKED   — Sonarr API knows this exact path → leave it alone
-#   PROTECTED — matches SONARR_PROTECTED_PATTERNS → never delete
-#   ORPHAN    — video file, not tracked, older than SONARR_ORPHAN_AGE → delete
-#   JUNK      — not a video extension, not protected → delete regardless of age
-#   RECENT    — not tracked, under SONARR_ORPHAN_AGE → skip (may be mid-import)
-#
-# Sonarr generates show artwork (*.jpg), metadata (*.nfo), and manages subtitles
-# (*.srt, *.sub, *.ass) but does NOT include these in its tracked file API response.
-# Without PROTECTED classification these would be deleted — breaking Sonarr and
-# Emby metadata display.
-#
-# After deletions: notify_emby_scan() triggers Emby "Clean Missing Files" task.
-# Emby removes ghost entries immediately — no user-facing file-not-found errors.
-#
-# ==============================================================================================
-# OPERATIONAL SAFEGUARDS
-# ==============================================================================================
-#
-# Six gates — ALL must pass before any file is touched:
-#   1. Container running and not starting/unhealthy
-#   2. API reachable
-#   3. API version matches SONARR_VERSION_MAJOR in master.conf
-#   4. Series count > 0
-#   5. Tracked file count > 0
-#   6. Deletion size < SONARR_MAX_DELETE_GB — or --i-know-what-im-doing required
-#
-#   acquire_lock "wait"  — large scans take time, wait for previous run to finish
-#   jq + curl validation — exits if either tool missing
-#   DOCKER_TIMEOUT       — container checks protected against daemon hangs
-#   notify_emby_scan()   — triggers Emby clean after deletion
-#   platform_require_cmd  — notify script validated before use
-#   Silent by default    — orphans/junk warn(), clean library logs silently
-#
-# ==============================================================================================
-# CONFIGURATION
-# ==============================================================================================
-#
-# host*.conf
-#
-#   HOST*_SONARR_URL / HOST*_SONARR_API_KEY / HOST*_SONARR_TV_ROOT
-#   HOST*_SONARR_PATH_MAP — container path → host path translation
-#   All aliased by detect_hosts() — script uses unprefixed names
-#
-# master.conf
-#
-#   SONARR_ORPHAN_AGE          — days before untracked file eligible for deletion
-#   SONARR_MAX_DELETE_GB       — require --i-know-what-im-doing above this
-#   SONARR_EXTENSIONS          — video file extensions for orphan classification
-#   SONARR_PROTECTED_PATTERNS  — file patterns never deleted
-#   SONARR_VERSION_MAJOR       — expected Sonarr major version for API safety check
-#   SONARR_IMPORT_SCAN_TIMEOUT — seconds to wait for pre-flight import scan (default 600)
-#   ARR_CLEANUP_STATS          — stats file path (read by coffee report)

+# Read-Only, No Network Calls
+#   All data comes from conf files — no SSH, no API calls, no pings. The output
+#   is always instant and never fails due to a node being unreachable. This makes
+#   it safe to run at any time without side effects.
+#
+# Scales Automatically
+#   Iterates all defined HOST* vars rather than a hardcoded list. Adding a new
+#   node to master.conf/host*.conf makes it appear in the output immediately.
+#
+# Safe to Share
+#   Output contains only identity and coverage configuration — no API keys,
+#   no passwords, no SSH keys. The report can be shared with other mesh members
+#   without exposing secrets.

+#
+# No External Dependencies
+#   Reads only from already-sourced conf files. No curl, no ssh, no docker —
+#   nothing that can fail, hang, or require credentials.
+#
+# Empty Mesh Guard
+#   collect_hosts() populates ALL_HOST_IDS — if no HOST* vars are defined the
+#   output sections iterate over an empty array and exit cleanly.
+#
+# No Root, No Lock, No detect_hosts — Deliberate
+#   This is the one script in the ecosystem that intentionally omits all three, and
+#   they should not be added. It writes nothing, so there is no state for a lock to
+#   protect and no privileged operation to justify a root gate. It reports on every
+#   node rather than acting as one, so detect_hosts() would narrow it to this host's
+#   aliases — the opposite of what it is for. Every HOST* var is read directly instead.

+# Varaverk AI Integration — Design Notes
+
+**Status: retrieval is built; integration is not.** As of 2026-08-02 the `AI_*` and
+`HOST*_OLLAMA_*` variables exist in both confs and both templates, and `AI/` holds a working
+index and query path — see the RAG section at the end of this document and `AI/README-AI.md`.
+
+Everything else below remains design only. **No Varaverk script consults AI.** Every
+`AI_ASSIST_*` toggle is false, `AI_CONF_WRITE_ENABLED` is false with an empty whitelist, and
+host resolution across the mesh is specified but not implemented. Originally captured
+2026-08-01 so the reasoning survives.
+
+Ollama itself *is* installed, tuned and verified on HOST1 — `qwen2.5-coder:14b` for
+generation, `nomic-embed-text` for embeddings, 16k context, pinned to the RTX 3080. See
+Hardware Budget for measured numbers. That is the substrate, not the integration.
+
+**Origin:** the RTX 3080 was freed when the Windows gaming VM was retired. It is bound to the
+`nvidia` driver, not `vfio` — not reserved for passthrough, so there is no VM contention to
+design around. Two goals at once: somewhere to learn local LLMs, and something Varaverk can
+genuinely use.
+
+**Build order** — deliberately lowest-risk first. Each stage must be boring before the next
+one starts:
+
+1. Chat assistant / settings helper / onboarding assistant — a wrong answer costs nothing
+2. Watchdog and discovery context — a wrong answer costs a bad suggestion, still gated
+3. Cleanup and sync decision aid — closest to destructive, last to be trusted
+
+The regular script is always the backup, at every stage.
+
+---
+
+## The governing principle
+
+**Varaverk works exactly as well with AI off as with it on.**
+
+Every script — including scripts written after this lands — is designed and hardened
+without AI first. AI is added afterwards as enhancement, never as a dependency. A script
+that cannot do its job when `AI_ENABLED=false` is a broken script, not an AI feature.
+
+This is the constraint everything else in this document answers to. If a design decision
+makes AI load-bearing, that decision is wrong.
+
+Corollary: AI never makes a destructive decision. The session that produced the current
+safeguard layer (depth guards, strike thresholds, verification-after-write) exists because
+config values and scan results feed `rm -rf`, `chown -R`, and rsync `--delete`. AI advises
+at the points where a script currently stops and defers to a human. The deterministic guard
+still pulls the trigger.
+
+---
+
+## Two independent off-switches
+
+| switch | meaning | source |
+|---|---|---|
+| `AI_ENABLED` | intent — do we want AI at all | `master.conf` |
+| resolver result | availability — is there a reachable host | runtime probe |
+
+**Both must produce the identical code path when off.** A caller that gets "no AI" from
+either must run its normal, non-AI logic — not a degraded variant, not a skipped step.
+
+`AI_ENABLED` follows the fail-closed idiom standardised across the ecosystem:
+
+```bash
+[[ "${AI_ENABLED:-false}" != "true" ]] && <normal path>
+```
+
+Not `== false`. Anything that isn't exactly `true` means off, so a typo can never switch AI
+on. (This is the same bug that was fixed in `fallback.sh` — see its `FALLBACK_ENABLED` gate.)
+
+---
+
+## Configuration schema
+
+Follows the existing rule: **thresholds and toggles → `master.conf`; hardware, paths,
+container names and per-host identity → `host*.conf`.**
+
+### `host*.conf` — per-host, because only one node actually has the GPU
+
+```bash
+# ━━━ Ollama / AI ━━━
+    HOST1_OLLAMA_URL="http://localhost:11434"   # empty on nodes without a local Ollama
+    HOST1_OLLAMA_CONTAINER="Ollama"             # for docker_watchdog / restart lists
+    HOST1_OLLAMA_GPU_UUID="GPU-309357d8-2a13-09e0-84ac-fcfdcdf5c626"
+    HOST1_OLLAMA_MODEL="qwen2.5-coder:14b"      # generation
+    HOST1_OLLAMA_EMBED_MODEL="nomic-embed-text" # embeddings — qwen cannot embed
+```
+
+A node with an empty `OLLAMA_URL` is not an error — it falls through to the resolver and
+uses the mesh. HOST2 gets the section with blanks, exactly like the NPM/lldap credentials
+it is already waiting on.
+
+### `master.conf` — shared behaviour
+
+```bash
+# ━━━ AI ━━━
+    AI_ENABLED=false                # master switch — fail-closed, != "true" means off
+    AI_CONNECT_TIMEOUT=5            # probe timeout when resolving a host
+    AI_REQUEST_TIMEOUT=240          # must clear a cold load — measured 1m45s after tuning.
+                                    # KEEP_ALIVE=-1 means this only bites after a restart,
+                                    # but a first call that times out is the worst first
+                                    # impression a caller can have. Re-measure against a
+                                    # real RAG query before fixing this number.
+    AI_RESOLVE_CACHE_TTL=300        # don't re-probe the mesh on every script invocation
+    AI_MAX_RETRIES=1                # AI is enhancement — do not retry hard
+
+    # Per-feature toggles — enable narration long before enabling decision aid
+    AI_ASSIST_REPORTS=false         # tier 1 — digest / coffee report narration
+    AI_ASSIST_WATCHDOG=false        # tier 2 — context on a flagged condition
+    AI_ASSIST_DISCOVERY=false       # tier 2 — discovery / classification judgment calls
+    AI_ASSIST_CLEANUP=false         # tier 2 — HELD orphans, stuck-import triage
+    AI_ASSIST_ONBOARD=false         # tier 3 — onboarding / settings assistance
+
+    # Conf writes — separate switch, off by default, see Conf Write Access below
+    AI_CONF_WRITE_ENABLED=false
+    AI_CONF_WRITE_KEYS=()           # explicit whitelist; never paths or credentials
+```
+
+**Per-feature toggles are load-bearing, not decoration.** They are what lets AI narrate the
+weekly digest for months before it is ever allowed near a cleanup decision. `AI_ENABLED` is
+necessary but not sufficient — every feature stays individually off until it has earned it.
+
+> When these land, `Deployment/master.conf.template` and `Deployment/host.conf.template`
+> must be updated in the same pass. That rule is not optional in this repo.
+
+---
+
+## Host resolution
+
+AI runs on the owner's node only. Remote mesh nodes reach it over Tailscale. No remote node
+needs a GPU, a model, or an Ollama container — only the resolver.
+
+`resolve_ollama_host()` mirrors the existing Gitea locator in `git_pull_execute.sh`:
+
+```
+Ollama answering on localhost:11434?      → use it            (owner's node)
+  else discover_remote_nodes()
+       → resolve_tailscale_ip(node)
+       → probe each :11434                → first responsive wins
+  else                                    → no AI host        (== AI_ENABLED=false)
+```
+
+Helpers already exist in `common.sh`: `discover_remote_nodes()` (767),
+`resolve_tailscale_ip()` (812), `check_connectivity()` (866).
+
+**Probe the API, not the container.** The Gitea locator checks `docker ps`. Do not copy that
+here — a container can be up while the model is unloaded, still pulling, or wedged. Probe
+`/api/tags`. Same principle written into `network_watchdog.sh`'s design principles:
+*verify the path, not the process*.
+
+**Cache the resolution** in `/tmp` state, like the arr cache. A cleanup script should not pay
+a Tailscale round-trip to discover AI it may never call.
+
+### Known consequence
+
+AI lives on HOST1, so **during a fallback — HOST1 down, HOST2 covering — the mesh has no AI.**
+That is precisely when a triage assistant would be most useful. Accepted: a second GPU on
+HOST2 is a lot of hardware for that window, and AI is enhancement-only by design. Worth
+knowing rather than discovering.
+
+---
+
+## Where AI is allowed to act
+
+Ranked by how much damage a wrong answer does.
+
+**Tier 1 — narration and summary (safe, do first)**
+- Sunday morning coffee report — turn metrics into prose
+- `weekly_health_digest.sh` — summarise, highlight what changed
+- Explain *why* a container is crash-looping from its logs
+
+**Tier 2 — triage and context on an existing flag (the real value)**
+Places where a script already detects something and stops:
+- `system_watchdog` / `stability_watchdog` flags a condition → AI adds context, correlates
+  with recent logs, suggests likely cause
+- Sonarr stuck-import triage — the "matched by series ID" recipe is textbook LLM work
+- `HELD` entries from `arr_download_orphan_cleaner.sh`
+- `reverse-anime-leak` from the classification scans — currently report-only *because* it is
+  a judgment call. That is exactly the shape AI suits.
+
+**Tier 3 — assisted configuration (needs the guardrails below)**
+- Onboarding a new host — the main motivation for conf write access
+- AI-assisted settings tuning: rsync profiles, fallback tiers, auth stack
+
+**Never**
+- Deciding what to delete
+- Choosing a path for any destructive operation
+- Anything that bypasses a strike counter, age gate, or verification step
+
+---
+
+## Conf write access
+
+Wanted mainly for onboarding and assisted settings. This is the highest-risk item here.
+
+**Current state: there is no recovery path.**
+
+```
+.gitignore:4  Configurations/host*.conf
+.gitignore:5  Configurations/master.conf
+.gitignore:6  Configurations/*.bak
+```
+
+Confs are gitignored — no git history to revert to — and so are the `.bak` files, so the
+backup is not versioned either. The only fallback is a single `.bak` slot written by
+`conf_upgrade`, and it goes stale immediately:
+
+| file | modified | its `.bak` |
+|---|---|---|
+| `master.conf` | Jul 28 18:52 | Jul 28 18:52 |
+| `host1.conf` | Aug 1 21:00 | **Jul 3 17:46** |
+
+A bad write to `master.conf` currently falls back to a file that may predate a month of edits.
+**Fix this before any AI writes anything.**
+
+### Required before conf-write ships
+
+1. **Key whitelist, not file access.** Thresholds and toggles only — `*_WARN_GB`,
+   `*_STRIKE_LIMIT`, `*_ENABLED`, retention days. Never a path, never a credential, never a
+   container list. A wrong threshold is recoverable; a wrong path is what the depth guards
+   exist to catch.
+2. **Timestamped backups, plural** — `master.conf.2026-08-01T21:00`, retained. Not one
+   clobbered slot.
+3. **Validate before commit** — `bash -n` the candidate, then confirm `load_config.sh`
+   sources it cleanly. Never install a conf that has not been proven to parse.
+4. **Diff always logged.** An AI conf change should be at least as visible as a container
+   restart.
+5. **Lock against concurrent readers** — never rewrite a conf while scripts are mid-run.
+
+**Consider un-ignoring `Configurations/` into a private repo.** Then `git diff` and
+`git revert` become the recovery mechanism and the history is free. This overlaps the
+existing GitHub-mirror TODO, which is already blocked on the same question.
+
+---
+
+## Security
+
+Ollama has **no authentication of any kind**, and its API includes `DELETE /api/delete`
+(wipe models) and `POST /api/pull` (fill the disk). It currently binds `0.0.0.0:11434` with
+`OLLAMA_ORIGINS=*` — reachable from the entire LAN, not just Tailscale.
+
+The design only needs loopback (owner) plus the Tailscale interface (mesh). `0.0.0.0` is
+strictly wider than required, for no benefit. Restrict to loopback + Tailscale, or use
+Tailscale ACLs to allow only mesh nodes. Node-level ACLs fit the mesh model better than
+app-level auth Ollama cannot provide anyway.
+
+**Done 2026-08-01:** `/ext-varaverk` is now mounted `ro` (was `rw` into live prod).
+Verified on the running container — `rw=false`.
+
+**Still open:** the LAN exposure above. Deliberately not folded into the tuning rebuild,
+since bind-address versus Tailscale ACL is a decision rather than a setting.
+
+---
+
+## Hardware budget
+
+RTX 3080, 10 GB, pinned to Ollama by UUID — isolated from the Quadro P2000 that Emby
+transcodes on. Do not let AI onto the P2000.
+
+**Tuned and measured 2026-08-01.** These are observed values, not estimates.
+
+| | before | after |
+|---|---|---|
+| `OLLAMA_NUM_PARALLEL` | 2 | **1** |
+| `OLLAMA_KV_CACHE_TYPE` | f16 | **q8_0** |
+| `OLLAMA_CONTEXT_LENGTH` | 4096 | **16384** |
+| `OLLAMA_FLASH_ATTENTION` | false | **true** |
+| VRAM used | 9298 MiB (91%) | **8811 MiB (86%)** |
+| warm latency | 2.6s | **1.85s** |
+| cold load | 28.6s | **1m45s** |
+
+`/api/ps` confirms `ctx=16384` — the increase is real, not just an env var.
+
+**4× the context for less VRAM than before.** Flash Attention plus the quantized KV cache
+more than paid for the increase. Cold load got much slower, which is irrelevant while
+`OLLAMA_KEEP_ALIVE=-1` pins both models — but it is felt after any container restart.
+
+### Flash Attention is mandatory, not optional
+
+`OLLAMA_KV_CACHE_TYPE=q8_0` **will not load** without it:
+
+```
+llama_init_from_model: V cache quantization requires flash_attn
+llama-server process no longer running: exit status 1
+```
+
+Quantized K/V cache requires Flash Attention. Supported on Ampere and newer; the 3080
+qualifies. If the KV cache type is ever changed back toward a quantized value, Flash
+Attention must be on or the model silently fails to load and every call errors.
+
+### Tuning order still matters
+
+If these are ever re-tuned from defaults, the order is load-bearing — raising context first
+at high utilisation will OOM:
+
+1. `OLLAMA_NUM_PARALLEL` → 1 (each slot multiplies KV cache)
+2. `OLLAMA_FLASH_ATTENTION` → true (prerequisite for the next step)
+3. `OLLAMA_KV_CACHE_TYPE` → q8_0 (roughly halves KV memory)
+4. *then* `OLLAMA_CONTEXT_LENGTH` upward
+
+32k was considered and rejected — projected ~1000 MiB of KV, leaving under 450 MiB headroom.
+16k is the comfortable ceiling for a 14B on this card.
+
+### Concurrency
+
+**You cannot have 14B + long context + real parallelism on 10 GB.** Pick two.
+`OLLAMA_MAX_QUEUE=512` means excess requests queue rather than fail, and at ~2s responses,
+two or three users serialised is barely noticeable. Multi-user hits are expected to be rare.
+So: parallelism stays at 1, the queue absorbs bursts, and the VRAM goes to **context** —
+which is what RAG actually needs.
+
+### Applying template changes
+
+**Unraid's "Apply" does not reliably recreate the container.** Observed 2026-08-01: the
+template was saved correctly but the container was only *restarted*, so the env vars never
+took effect — `Created` stayed unchanged while `Started` advanced. Env changes require a
+remove-and-recreate.
+
+Force it with Unraid's own script:
+
+```bash
+/usr/local/emhttp/plugins/dynamix.docker.manager/scripts/rebuild_container Ollama
+docker start Ollama      # rebuild stops it — Ollama is not in unraid-autostart
+```
+
+Verify with `docker inspect Ollama --format '{{.Created}}'` — the timestamp must move.
+Checking the env vars alone is not enough; a restart leaves the old ones in place and
+looks like nothing happened.
+
+---
+
+## RAG
+
+No Python on Unraid, and none needed. Everything required is already present:
+`sqlite3 3.53`, `jq 1.8`, `node 22`, `php 8.4`, `awk`.
+
+- **chunks + vectors** → SQLite, one table
+- **similarity** → cosine in PHP or Node; milliseconds at this corpus size, no vector DB
+  container needed
+- **embed + generate** → Ollama HTTP, same `curl` pattern as every other integration here
+
+Note `qwen2.5-coder` returns `501 — does not support embeddings`. Embedding is
+`nomic-embed-text`'s job. Batch embedding works (n inputs → n vectors in one call) and is
+required — indexing 50k lines one HTTP call at a time is not viable.
+
+---
+
+### The corpus — and why its shape matters more than its size
+
+As of 2026-08-01, after the header audit and the per-folder documentation pass:
+
+| Layer | Size | What it answers |
+|-------|------|-----------------|
+| Script headers | 115 files × 6 sections = **690 chunks**, 14,685 lines | "What does *this script* do, and why that way" |
+| Folder docs | 18 `README-*.md` + 13 `Manual-*.md` | "How does this *group* work" / "how do I do the thing" |
+| Top-level | `README.md`, `Manual.md` | "What is this system" |
+| Conf templates | 2,175 lines, **~55% comment** | The schema, self-describing |
+| Bash bodies | 51,166 lines | Implementation — index last, lowest weight |
+
+Markdown total: **13,516 lines.** Still small enough that cosine over the whole set is
+milliseconds.
+
+**Chunking is already solved, and the audit is what solved it.** Every script carries
+`PURPOSE / OPERATIONAL MODEL / DESIGN PRINCIPLES / OPERATIONAL SAFEGUARDS / CONFIGURATION /
+RUNTIME MODES` — **115 of 115, no exceptions.** Split on `^# SECTION NAME$` and every chunk is
+a semantically coherent unit by construction. The single worst failure mode in naive RAG —
+a fixed-size window cutting mid-thought and embedding two half-ideas as one vector — cannot
+happen here. Median header is 117 lines, so a section lands around 130–200 tokens: comfortably
+inside `nomic-embed-text`'s window, no sub-splitting needed.
+
+**Store the section name as a column, not just as chunk text.** This is the highest-value
+thing the audit bought and it should not be thrown away at index time. Section type is a free
+metadata filter, so retrieval can route before it computes similarity:
+
+| Question shape | Filter to |
+|----------------|-----------|
+| "what stops X and Y overlapping" | `OPERATIONAL SAFEGUARDS` |
+| "what variable controls X" | `CONFIGURATION` |
+| "does this take --dry-run" | `RUNTIME MODES` |
+| "why is it built this way" | `DESIGN PRINCIPLES` |
+| "what does this script do" | `PURPOSE` |
+
+Hybrid retrieval essentially for free, because every chunk already has a type.
+
+Suggested table shape:
+
+```sql
+CREATE TABLE vv_chunks (
+    id        INTEGER PRIMARY KEY,
+    path      TEXT NOT NULL,     -- repo-relative
+    kind      TEXT NOT NULL,     -- header | readme | manual | template | body
+    section   TEXT,              -- PURPOSE, OPERATIONAL SAFEGUARDS, ... (NULL for md/body)
+    heading   TEXT,              -- md ## heading, for doc chunks
+    content   TEXT NOT NULL,
+    vector    BLOB NOT NULL,     -- 768 float32
+    indexed   INTEGER NOT NULL   -- epoch; re-embed on mtime change only
+);
+```
+
+### Why this corpus is worth more than an equivalent pile of code
+
+A model can read `mover_stop.sh` and describe what it does. What it *cannot* derive from any
+amount of source is that a thing was done deliberately. The audit wrote those down:
+
+- the API cache writers are lockless and unprivileged **on purpose** — regenerable within a
+  minute, every consumer has a live fallback
+- `removeCompletedDownloads` / `removeFailedDownloads` both true is **intended**, not an
+  oversight
+- the arr cleanup ctime gate depends on `media_shares_permissions.sh` staying conditional —
+  reverting either silently stops orphan collection
+- `mesh_monitor.sh`, `adapter.sh`, `decision_engine.sh`, `containers.sh` and
+  `api_cache_writer.sh` carry no root check and no lock **by design** — each documents why in
+  its own header (libraries that must not `exit`, read-only probes, or regenerable output
+  with a live fallback)
+
+Without those in the index, the most likely contribution from an AI assistant reviewing this
+repo is a confident regression: *"I notice this script lacks a lock."* Weight
+`DESIGN PRINCIPLES` and `OPERATIONAL SAFEGUARDS` heavily for any suggest-a-change flow —
+they are the guardrails against the assistant helpfully undoing a decision.
+
+### Indexing is safe by default — keep it that way
+
+`Configurations/*.conf` is gitignored; `Deployment/*.template` is tracked and carries all the
+explanatory comments. The corpus therefore describes the full schema while structurally
+**never containing a credential**, because the credential-bearing files were never in the repo
+to begin with.
+
+Treat that as a deliberate boundary, not a happy accident:
+
+- **index tracked files only** — never walk `Configurations/` or `data/`
+- a live conf value that the model genuinely needs should arrive through a *tool call* at
+  query time, subject to the same redaction rules as everything else in the Security section,
+  not be baked into a vector at index time
+- an embedded secret is unrevocable in a way a logged one is not — there is no rotation story
+  for a value already averaged into a 768-dim float
+
+### Known gap — the PHP layer is not covered
+
+78 PHP files under `Plugin/unraid/`; **2** carry a `PURPOSE` block. The entire web UI —
+`pages/`, `api/`, `include/` — is effectively invisible to retrieval.
+
+Consequence: any "AI helper per Varaverk page" feature has this as a hard prerequisite. A
+page-scoped assistant that cannot retrieve the page's own logic is worse than no assistant.
+
+`include/` is the high-value subset to do first — 16 files, and both the pages and the API
+endpoints route through the same `vv_*()` builders, so documenting it once covers both
+callers. This is a follow-on pass, not a blocker for indexing bash.
+
+---
+
+## Scheduled AI
+
+Same orchestrator tiers as everything else, gated on `AI_ENABLED` plus a reachable host.
+Natural fits: weekly digest narration, a periodic pass over `HELD`/report-only findings that
+have accumulated, post-incident summaries after a watchdog event.
+
+Must obey the existing tier discipline — an AI job that fails or times out is a non-fatal
+step like any other, and never blocks the rest of its tier.
+
+---
+
+## UI
+
+- **Dedicated AI page** in the plugin.
+- **Persistent conversation across pages.** A floating widget is not required — a chat column
+  is fine. The constraint is that Unraid's WebGUI is multi-page PHP with full reloads and no
+  SPA shell, so persistence means conversation state lives server-side keyed by session, with
+  the client re-hydrating per page.
+- **Per-page AI helpers** — contextual assistance scoped to whatever that page is about.
+
+---
+
+## "Too bad we can't just run the LLM inside Varaverk and cut out Ollama"
+
+There is a real answer: you don't cut Ollama out, you **absorb it**.
+
+Ollama does non-trivial work — model lifecycle, GPU scheduling, keep-alive, batching, an HTTP
+API. Reimplementing that in bash is not a good trade. But Varaverk already manages containers
+better than most things manage containers. Ollama becomes just another managed container:
+
+- add to `HOST*_WATCHDOG_CONTAINERS` so `docker_watchdog.sh` keeps it healthy
+- add to a restart list so it gets the same proactive treatment as everything else
+- give it a fallback tier if AI should survive a host outage
+- let `docker_update.sh` handle its image updates
+
+That is more Varaverk-native than embedding a model runtime would be, and it costs nothing
+new — the machinery already exists and was audited this session.
+
+---
+
+## Open questions
+
+- Un-ignore `Configurations/` into a private repo for conf history? (blocks conf-write, and
+  overlaps the GitHub-mirror TODO)
+- Does the AI page need auth separate from the Unraid WebGUI, given remote mesh members?
+- Retention/privacy for conversation history — logs may contain paths, container names,
+  possibly credentials pasted by a user.
+- Is a 7B worth it to buy context + parallelism headroom, or is 14B quality worth the
+  serialisation? Defer until an actual problem is felt.
+
+---
+
+## RAG — built 2026-08-02
+
+Retrieval is live. `AI/` holds the implementation; `AI/README-AI.md` documents it in full. What
+follows is only what changed relative to the plan recorded above.
+
+**Corpus is larger than estimated.** ~2,950 chunks across ~180 files, not the 690 header chunks
+projected. Sub-chunking is why — see below.
+
+**Named-paragraph sub-chunking was necessary, and was not in the plan.** Section-level chunks
+alone were too coarse. `rsync.sh` documents fourteen safeguards in one 2.8k-char
+`OPERATIONAL SAFEGUARDS` block; a query about one of them scored 0.558, below unrelated chunks,
+because the other thirteen dominated the vector. Splitting on the named-paragraph titles the
+header convention already uses took the same query to 0.718 and first place. The parent section
+name is carried onto each sub-chunk so routing still works.
+
+**Two chunker bugs worth remembering.** The last section in a header (RUNTIME MODES in bash,
+DEPENDS ON in a page) ran to EOF and swept up every unrelated comment in the file —
+`scheduler.php` alone produced an 11k-char chunk of unrelated inline comments. And title
+detection must require the *next* line to be indented; without that, any wrapped prose line
+became a spurious chunk boundary mid-sentence.
+
+**Section routing is a boost, not a filter.** Intent detection is a heuristic and must not be
+able to exclude the chunk holding the answer. `--section=` forces a hard filter when wanted.
+
+**Vectors arrive pre-normalised.** `nomic-embed-text` returns L2-normalised vectors (measured
+norm 1.0000001), so cosine is a plain dot product. No normalising step, no magnitude cache.
+
+**`node:sqlite` over a native module.** Still flagged experimental, chosen because it needs no
+native compilation on Unraid. Acceptable because the index is disposable — if a Node upgrade
+breaks it, rebuild takes minutes. PHP reads the same float32 blobs with `unpack('f*', $blob)`
+when the UI needs them.
+
+**Retrieval quality, measured.** 9/10 top-3 hit rate on known-answer questions; the tenth had
+the answer at ranks 2 and 3, so 10/10 for answer-present-in-context at k=6. Full retrieval plus
+generation runs about 43s warm.
+
+### The finding that validated the whole thing
+
+First real end-to-end question asked which variable controls the mover's grace window. The model
+answered `MOVER_STOP_TIMEOUT`, "defaults to 30 seconds", citing `mover_stop.sh › CONFIGURATION`.
+Variable correct; the 30 was wrong — the real value is 300. The model was quoting the header
+verbatim. **The header was stale.**
+
+A sweep for the same pattern found six stale `(default: N)` claims across the repo — all
+corrected in the same pass. This is the operating principle for the folder:
+
+> Retrieval is exactly as accurate as the documentation it points at. When an answer looks
+> wrong, check the cited source before blaming the model.
+
+It also means the index is a documentation-drift detector, not only a question-answering tool.
+
+### Still deliberately not built
+
+Nothing consults this. Every `AI_ASSIST_*` toggle is false, `AI_CONF_WRITE_ENABLED` is false
+with an empty key whitelist, and no watchdog, cleanup or fallback path calls it. Host resolution
+across the Tailscale mesh is specified above but not implemented — `ai_index.sh` and
+`ai_query.sh` currently require a local `HOST*_OLLAMA_URL` and fail with a clear message when it
+is empty, rather than silently probing the mesh.

 #
 #   NOTE: watchdogs (docker, system, stability) are NOT launched here.

 #
-# ── WHY ORDER MATTERS ─────────────────────────────────────────────────────────────────────────
-#   unraid_api_key_renew.sh — before anything else — self-heals API registry at boot
-#   inotify_tuning.sh     — must run BEFORE Code-Server and other containers start
-#                           containers that start with low inotify limits keep them ✅

-#   notify on failures   — alert if any script fails to launch
+# ==============================================================================================
+# DESIGN PRINCIPLES
+# ==============================================================================================
+#
+# Order Is Load-Bearing
+#   inotify limits must be raised before containers start — containers that
+#   start with low limits keep them. Ramdisk must exist before Emby starts.
+#   Docker networks must be connected before watchdogs check container states.
+#   fallback.sh goes last — it needs everything else stable to make decisions.
+#
+# Configuration Owns the List
+#   ARRAY_START_SCRIPTS in master.conf is the only place scripts are added or
+#   removed. This orchestrator never needs to be edited to change what runs —
+#   one-shot vs continuous behaviour is auto-detected from the PID after launch.
+#
+# ==============================================================================================
+# OPERATIONAL SAFEGUARDS
+# ==============================================================================================
+#
+# Root Enforcement
+#   Every script launched here requires root.
+#
+# Lock Acquisition
+#   acquire_lock prevents duplicate array start launches. Unraid can fire the array
+#   start hook more than once, and a second pass would re-launch continuous scripts
+#   that are already running.
+#
+# Host Detection
+#   detect_hosts() sets MY_ID for notifications.
+#
+# Empty Job List Guard
+#   Exits with an error and a notification if ARRAY_START_SCRIPTS is empty. An empty
+#   list would silently bring the array up with no ramdisk, no network setup, no
+#   watchdogs and no fallback — while reporting a clean start.
+#
+# Executable Auto-Fix
+#   Non-executable scripts are chmod +x'd before launch. A permission bit lost to a
+#   git checkout or a file copy should not silently disable a boot-time component.
+#
+# Full Path on Failure
+#   Failures report the exact resolved path, so a missing script is immediately
+#   distinguishable from a script that ran and failed.
+#
+# Failure Notification
+#   Any script that fails to launch raises a notification — array start is unattended,
+#   so a silent failure here would only surface much later as a missing service.

+#
 #   1. user_scripts_stop.sh        — kill background user scripts (prevents new operations)
 #   2. rsync_stop.sh --rsync-only  — kill rsync; skip container recovery (handled in step 4)

-# ── WHY THIS ORDER ────────────────────────────────────────────────────────────────────────────
-# User scripts stopped first — they can spawn new rsync/docker operations mid-shutdown.
-# Rsync before mover — both write to the same paths; running together risks corruption.
-# Containers last — apps should stay available as long as possible during shutdown prep.

+#   User scripts are stopped first — they can spawn new rsync or docker operations
+#   mid-shutdown. Rsync stops before mover — both write to the same paths and
+#   running together risks corruption. Containers stop last — apps should stay
+#   available as long as possible during shutdown prep.
+#
+# Non-Fatal Steps
+#   A failed stop step is logged and notified but does not abort the sequence.
+#   Remaining scripts still run — a partial stop is better than a halted one.
+#
+# ==============================================================================================
+# OPERATIONAL SAFEGUARDS
+# ==============================================================================================
+#
+# Root Enforcement
+#   Every stop script launched here requires root.
+#
+# Lock Acquisition
+#   acquire_lock prevents concurrent array stop runs. Two overlapping shutdown
+#   sequences would fight over the same containers.
+#
+# Host Detection
+#   detect_hosts() sets MY_ID for notifications and logs.
+#
+# Empty Job List Guard
+#   Exits with an error and a notification if ARRAY_STOP_SCRIPTS is empty. An empty
+#   list means the array stops without saving the conf cache or gracefully stopping
+#   containers — the failure would only be discovered at the next boot.
+#
+# Non-Fatal Steps
+#   A failing stop script is recorded and the remaining ones still run. Abandoning the
+#   shutdown sequence partway would leave more state unsaved than continuing does.
+#
+# Failure Notification
+#   Any failing stop script raises a notification. Shutdown is unattended and its
+#   failures are invisible until they cause a problem on the way back up.

+#
+# ==============================================================================================
+# OPERATIONAL SAFEGUARDS
+# ==============================================================================================
+#
+# Root Enforcement
+#   rsync and docker operations require root.
+#
+# Lock Acquisition
+#   acquire_lock prevents two daily windows overlapping — the window is long and a
+#   second pass would contend for the same shares and containers.
+#
+# Host Detection
+#   detect_hosts() aliases the correct per-host share and script lists.
+#
+# Empty Job List Guard
+#   Exits with an error and a notification if DAILY_MAINTENANCE_SCRIPTS is empty. This
+#   is the largest tier in the ecosystem — an empty list would silently skip git pull,
+#   permissions, cleaners, arr cleanup and docker updates while reporting a clean run.
+#
+# Connectivity Check
+#   check_connectivity is verified before any rsync is attempted.
+#
+# Remote Rootfs Check
+#   check_remote_rootfs aborts rsync if the remote rootfs is nearly full, rather than
+#   pushing data to a partner that cannot hold it.
+#
+# Drive Temperature Escalation
+#   rsync.sh's exit code is honoured per share: exit 1 (temp WARN) skips that share and
+#   continues; exit 2 (temp CRITICAL) sets ABORT_ALL_SYNCS so every remaining share in
+#   the window is skipped and a notification is raised. Continuing to hammer drives that
+#   are already too hot is how a thermal warning becomes a dead disk.
+#
+# Non-Fatal Jobs
+#   A failed job is logged and the remaining jobs still run. Partial completion of a
+#   maintenance window beats abandoning it at the first error.
+#
+# Quiet on Success

-# Uptime-triggered monthly maintenance — runs heavy tasks that need a stable, settled system.
+#
+# PURPOSE
+# ─────────────────────────────────────────────────────────────────────────────
+# Uptime-triggered monthly maintenance — runs heavy tasks that need a stable,
+# settled system. Schedule: 0 0 15 * * (15th of each month at midnight)
 # Fires only when BOTH gates pass:
 #   1. Server uptime >= MONTHLY_UPTIME_THRESHOLD_DAYS days
 #   2. Last run was >= MONTHLY_RUN_INTERVAL_DAYS days ago (or never run)
 #
-# ── WHY UPTIME-GATED ─────────────────────────────────────────────────────────────────────────
-#   A scheduled reboot resets uptime. Monthly tasks (ZFS scrub, SMART long test) need a
-#   stable, settled system — not one that just rebooted. Uptime-gating ensures maintenance
-#   only runs after the server has been healthy for a full month, never immediately post-boot.
-#   If uptime or interval gate is not met on the 15th, the run is skipped until next month.

+# Silent exit 0 when either gate is not met — only outputs when maintenance fires.
+# If uptime or interval gate is not met on the 15th, the run is skipped until
+# next month.
 #
-# ── STATE FILE ────────────────────────────────────────────────────────────────────────────────
-#   MONTHLY_LAST_RUN_FILE — /boot/config — survives reboots, available before array starts.
-#   Written after each run (pass or partial fail). Format: Unix timestamp.
-#   A reboot does NOT reset the last-run state — the interval gate survives independently
-#   of the uptime gate. Both must pass before maintenance fires again.
+# STATE FILE
+#   MONTHLY_LAST_RUN_FILE lives on /boot/config — survives reboots, available
+#   before the array starts. Written after each run (pass or partial fail).
+#   Format: Unix timestamp. A reboot does NOT reset the last-run state — the
+#   interval gate survives independently of the uptime gate.

+# Uptime Gate Ensures Stability
+#   A scheduled reboot resets uptime. Monthly tasks (ZFS scrub, SMART long test)
+#   need a stable, settled system — not one that just rebooted. Both gates must
+#   pass before maintenance fires, ensuring the server has been healthy for a
+#   full month.
+#
+# State Survives Reboots
+#   MONTHLY_LAST_RUN_FILE is on /boot/config (USB flash), not on the array.
+#   It is always available regardless of array state, so the interval gate is
+#   never lost to a reboot.
+#
+# ==============================================================================================
+# OPERATIONAL SAFEGUARDS
+# ==============================================================================================
+#
+# Root Enforcement
+#   ZFS scrub and SMART tests require root.
+#
+# Lock Acquisition
+#   acquire_lock prevents concurrent monthly runs. These are long jobs — a scrub can run
+#   for hours — and two at once would double the I/O cost for no benefit.
+#
+# Host Detection
+#   detect_hosts() sets MY_ID for notifications and logs.
+#
+# Empty Job List Guard
+#   Exits with an error and a notification if MONTHLY_MAINTENANCE_SCRIPTS is empty. A
+#   monthly job that silently does nothing is the hardest kind to notice missing.
+#
+# Uptime Gate
+#   MONTHLY_UPTIME_THRESHOLD_DAYS must be met before the run proceeds. Heavy full-disk
+#   work immediately after a boot competes with everything else still starting up.
+#
+# Interval Gate
+#   MONTHLY_RUN_INTERVAL_DAYS since the last successful run must have elapsed. The
+#   schedule fires more often than the work should actually happen, so the gate — not
+#   the cron entry — is what defines the real cadence.
+#
+# Force Override
+#   --force bypasses both gates for a deliberate manual run.
+#
+# Non-Fatal Steps
+#   A failing job is recorded and the remaining jobs still run.

+# Lock Acquisition
+#   acquire_lock prevents concurrent 7-minute cycles overlapping. Cleanup and the manager
+#   both touch the same ramdisk, and two cycles at once could have one deleting files
+#   while the other is measuring usage to decide whether to flip.

+# Host Detection
+#   detect_hosts() aliases RAMDISK_PATH, TRANSCODE_SSD and RAMDISK_WARN_GB per host.
+#
+# Empty Job List Guard
+#   Exits with an error and a notification if TRANSCODE_MANAGEMENT_SCRIPTS is empty —
+#   without it the ramdisk would silently stop being cleaned or flipped, and the first
+#   symptom would be a full ramdisk stalling playback.
+#
+# Ordering Is Load-Bearing
+#   Cleanup runs before the manager so the manager measures real active-session usage
+#   rather than usage inflated by stale files. Reversing them would trigger flips that
+#   a cleanup two seconds later would have made unnecessary.
+#
+# Dry Run Propagation
+#   --dry-run is passed through to every script in TRANSCODE_MANAGEMENT_SCRIPTS.
+#
+# Any-Failure Exit Code
+#   Exits 1 if any child failed, 0 otherwise — the individual exit codes are not

+# ==============================================================================================
+# OPERATIONAL SAFEGUARDS
+# ==============================================================================================
+#
+# Root Enforcement
+#   Container stop/start and rsync both require root.
+#
+# Lock Acquisition
+#   acquire_lock prevents concurrent weekly windows. This window stops Emby and the auth
+#   stack — two overlapping runs would fight over the same critical containers.
+#
+# Host Detection
+#   detect_hosts() sets MY_ID for the banner, summary and notifications.
+#
+# Empty Job List Guard
+#   Exits with an error and a notification if WEEKLY_MAINTENANCE_SCRIPTS is empty, rather
+#   than taking the weekly outage window and doing nothing with it.
+#
+# Connectivity Check
+#   check_connectivity verifies the remote before any remote operation is attempted.
+#
+# Remote Rootfs Check
+#   check_remote_rootfs aborts rsync if the remote rootfs is nearly full.
+#
+# Timeout Protection
+#   DOCKER_TIMEOUT bounds every docker call and SSH_TIMEOUT every SSH call, so neither a
+#   hung daemon nor an unresponsive partner can hold the weekly window open indefinitely.
+#
+# Non-Fatal Steps
+#   A failing job is recorded and the remaining jobs still run.

+# Separate Key From the Rsync Key

+#   never break cross-host rsync, and revoking a partner's rsync access should not lock this

+#
+# Idempotent Registration
+#   Both generation and registration are skipped when already satisfied, and registration is
+#   matched on the public key itself rather than on a label. A key registered under a

+#
+#   h2 (HOST2 → HOST1)

+# DESIGN PRINCIPLES
+# ==============================================================================================
+#
+# Safe at Any Phase
+#   Onboarding is multi-phase and can fail anywhere in it. This runs against whatever state

+#   a no-op, not an error. Cancelling twice is harmless.
+#
+# Direction Is Explicit
+#   Removing a key is not symmetric: it breaks authentication for whichever side loses it.
+#   The direction must be stated, and defaults to h1 (this host's own outbound key) rather
+#   than to both, so an unqualified run cannot sever the partner's access to you.
+#
+# Unwind, Do Not Repair
+#   The job is to return to a clean pre-onboard state so onboarding can be re-run from the
+#   top. It deliberately does not attempt to salvage or resume a partial setup — a known
+#   empty state is worth more than a guessed-at partial one.
+#

 # MIRROR PATH (8 steps)
 #   Step 1: Stop rsync          — halt any running sync
 #   Step 2: Reconfigure WebUIs  — local auth WebUIs → localhost
 #   Step 3: Remote stack clean  — remove owner-deployed containers locally (auth/arr stack)
 #   Step 4: Fallback cleanup    — remove fallback coverage containers
-#   Step 5: Disable sync        — CRITICAL_RSYNC_ENABLED=false in master.conf
+#   Step 5: Disarm sync gates   — same four gates as the owner path

+#                                 keys. Revocation is last because the signal needs the key
+#
+# ==============================================================================================
+# DESIGN PRINCIPLES
+# ==============================================================================================
+#
+# Sync Before Severing
+#   The final sync (owner step 2) runs before any state change, so the mirror leaves with
+#   current Critical-Data rather than a snapshot from whenever the last scheduled sync
+#   happened. Once keys are revoked there is no second chance to move data.
+#
+# Stop the Sync First
+#   Step 1 on both paths halts rsync before anything else. A sync running through a
+#   partnership teardown would be writing to a partner that is having its access removed
+#   underneath it.
+#
+# Revoke Last, Not First
+#   SSH keys and Emby admin are revoked at the end. Every earlier step needs working remote
+#   access — revoking up front would strand the remaining cleanup on the far side and leave
+#   the mirror holding containers nobody can remove.
+#
+# Both Sides Land Somewhere Valid
+#   Each path restarts the host's own parked containers before finishing. Offboarding must
+#   leave two working standalone servers, not one working server and one stripped of the
+#   coverage it was relying on.
+#
+# Role Detected, Not Declared
+#   Owner and mirror run different sequences, and the role is derived rather than passed in.
+#   A human choosing the wrong path would run the owner's remote-cleanup steps against a
+#   server that never deployed anything.
+#
+# Blocklist Is the Enforcement
+#   Writing INACTIVE state is not enough on its own — a stale cron or a script mid-flight
+#   could still attempt a sync. The mirror is blocklisted so rsync.sh refuses it outright,
+#   independently of whatever any config still says.
+#
+# ==============================================================================================
+# OPERATIONAL SAFEGUARDS
+# ==============================================================================================
+#
+# Root Enforcement
+#   Container removal, conf edits and SSH key revocation all require root.
+#
+# Lock Acquisition
+#   acquire_lock "strict" — an offboard is not resumable partway, so a second instance is
+#   refused rather than queued behind the first.
+#
+# Host Detection
+#   detect_hosts() resolves MY_ID / REMOTE_ID, which the role detection builds on.
+#
+# Docker Presence Check
+#   Verified before any container removal is attempted.
+#
+# Ordered Teardown
+#   The step sequence is the safeguard — sync, then reconfigure, then remove, then restart,
+#   then revoke, then record. Reordering breaks the guarantees above.
+#
+# Own Stack Restored
+#   Parked containers are brought back up on both sides before the run completes.
+#
+# State Written Both Ends
+#   INACTIVE is written locally and pushed to the mirror, so neither side is left believing
+#   a partnership is still active.
+#
+# Partner Blocklisted
+#   The mirror is added to the partnership blocklist, which rsync.sh checks and refuses on —
+#   stale access cannot survive the offboard.
+#
+# Tailscale Grace Window Is a Deadline, Not a Sleep
+#   Device removal happens after state is written, not before, so the final state push
+#   cannot be cut off by removing its own transport. The grace period itself is recorded to
+#   STATE_DIR/tailscale_removal_due.db and the offboard returns. It used to sleep
+#   PARTNERSHIP_GRACE_HOURS inline — six hours by default — holding the lock and its job record
+#   open the whole time, reporting "running", and blocking any re-onboard behind it.
+#
+# Dry Run Support
+#   --dry-run walks the full sequence reporting each step without executing any.
