The build-stamp edit replaced the header block's closing tag instead of
keeping it, opening a second php block inside the first. Deployed broken
because the lint in that commit printed OK unconditionally rather than
gating on php -l.
The tab bar uses Unraid's localURL, which swaps content by AJAX without
tearing down the previous page's JavaScript, so old copies keep their timers
and their state. That makes "is the browser running what I deployed"
unanswerable from the server, and explains banner polls arriving far faster
than the 30s timer. The page now stamps its build, says plainly when its own
script is not the one running, and stops the previous copy's timers.
A turn that ended without finish() left busy=true, so send() returned at line
one for every subsequent click — no fetch, no error, and the original
"starting…" still on screen. That is a hang which produces no request and so
no server-side trace of any kind. It now says what happened, and the pending
indicator carries an elapsed counter so stalled and merely slow look different.
GET reaches the endpoint and POST does not, with nothing in the request log,
no CSRF termination and no PHP error — so it fails in the browser before the
request goes out, and the only symptom was the pending indicator sitting
there. Reads the response as text before parsing so an empty body reports as
rejected-before-execution rather than a JSON error, wraps the synchronous
path, and surfaces script errors into the transcript.
The failures this subsystem actually has are configuration drift, so each
check names the setting to change rather than reporting that retrieval
failed. Notably it catches a conf model tag that is no longer installed, and
an index built by a different embedder than the one configured — vectors
from two models are not comparable, and that failure returns confident
nonsense rather than erroring. Diagnostic questions also get recent log
warnings, attached only then because they cost budget the passages need.
Token and poll rather than SSE, so the api layer keeps one response
convention and reuses the pattern manual_sync already proved. History is
capped at three turns because the model is only fully offloaded at 16384
context and unbounded history would cross that silently. The tab exists
only while AI_ENABLED is true, rejected server-side and not merely hidden.
