AI_INDEX_ON_PULL was designed, defaulted false, and never read by anything —
so nothing has ever rebuilt the index automatically. A pull is the only thing
that changes tracked files on a server, which makes it the only moment the
index can go stale, and a timer would do nothing 23 times a day while still
drifting from the pull that matters.
Staleness is invisible in the answers: the index keeps returning the old text
with confident, correct-looking citations. Gated on pull success, on
AI_INDEX_ON_PULL and on AI_ENABLED, and never fatal — a git pull must not fail
because an embedding call timed out.
"What is Varaverk" matched the PURPOSE intent, so retrieval returned every
script's one-line purpose and the model answered that the context does not
define the system — while README.md sat in the index unread. A definitional
question with no explicit filter now goes to kind=readme.
Varaverk is a coined word with no spell-check, so it arrives as varavrk,
veraverk, varavek. Edit distance catches those without a pattern that needs
extending per typo. This is search, not identity — a near-miss only widens a
document search, unlike hostname resolution where it must never resolve.
Custom Scripts run as root on a schedule, so the expensive mistake is not
tangled logic — it is a simple script aimed one directory too high. The prompt
now asks for the dry-run form and an explicit line on what gets destroyed, and
a scan of the generated code blocks raises a banner regardless of whether the
model bothered to warn. Scans fenced code only, so prose mentioning rm does not
trip it.
Given its own broken script and the real error, it produced the correct fix but
explained --no-overwrite away as 'introduced in a later version of rsync'. No
rsync version has ever had that flag, and the operator is on current 3.4.4 — so
the repair was right and the diagnosis was a second fabrication that would send
someone hunting a nonexistent upgrade.
The pattern required three underscore-separated segments, so RSYNC_ENABLED and
AI_ENABLED slipped through — exactly the names most likely to be asked about.
Also dropped the case-insensitive flag, which made the SCREAMING_CASE branch
match ordinary lowercase words containing underscores.
Asked what mover_stop.sh does, it invented a description and dressed it in
real memory facts so it read as authoritative — the exact failure the profile
split exists to prevent. A polite instruction in a system prompt is not a
guard. The rule now leads and is absolute, and a deterministic check repeats
it immediately before the message whenever the question names a shell script,
a SCREAMING_CASE conf key, or Varaverk itself. Detection can only make the
model more cautious, so a false positive costs a redirect, not an answer.
