Health messages go straight from each arr's API into innerHTML and quote things
nobody here controls — indexer names from Prowlarr, import-list names, release
titles. The page used no escaping at all. _sz() was also binary while labelling
its output TB, so /tv read 86.9 TB here and 95.6 TB on every other tab; it has
one caller and that caller is disk capacity, so it now matches the rest.
A multipart POST to the plugin API hangs and never completes on this host: no
status code, and no server-side trace of any kind. The correlation was exact —
every page using URLSearchParams worked, every page using FormData hung, which
is why scheduler and partnership appeared fine while docker, rsync, settings,
auth, arrs, fallback and monitor did not. URLSearchParams has the same append
API and fetch sets the urlencoded content type for it, so each site is a
one-token change with the payload logic untouched.
Unraid already enforces CSRF on every POST via auto_prepend, but its
injector is jQuery-only — the plugin's native fetch() calls carried no
token and were being terminated before the endpoint ran, silently,
because csrf_terminate exits with an empty body that r.json() swallows.
Documents each tab's purpose, what it renders, and which endpoints it polls.
Pages that start with markup get the header in a <?php ?> block so it never
reaches the browser.
Also corrects the layer diagram in README-unraid.md: eight of eleven pages hold
no PHP logic and poll api/ for everything — only auth, monitor and scheduler
require an include/ file directly.
