CI flake root cause (Gitea runner, anpr-entry.test.ts "records an advisory
anpr-skip"): the poll-until-confident loop was a plain
`while (Date.now() < deadline)` — zero iterations were possible when the
window elapsed between deadline-set and loop-entry (the tests run a 5ms
window; a slow runner loses that race). Zero attempts → no frame analyzed →
"gave up" → no anpr-skip row → assertion fails. Not a regression: nothing in
the recent merges touched this path; the race existed since the poll loop
was built.
The invariant is real beyond tests: on a sufficiently loaded booth the old
loop could silently drop a real car's detection the same way. The loop is
now do-while (exit via the existing breaks: confident read, or next tick
past the slid deadline/hard cap), so a detection ALWAYS analyzes at least
one frame.
New regression test forces ANPR_POLL_WINDOW_MS=0 (the CI scenario, made
deterministic) and asserts exactly one capture attempt + the recorded skip.
Suite 283 green.
