Field report (park-buzi): a BLINKING entry button still printed — the lamp
encoded blink-vs-solid (radar-only vs radar+camera) but #suppressReason only
checked the radar, so a radar false-positive (rain, pedestrian) minted a real
signed ticket. Three layered fixes:
1. CAMERA gate on the physical press: with an entry camera configured, a press
is live only in the lamp's SOLID state (LaneStatus.entry busy, mirrored into
EntryFlow via onLaneStatus). Suppress-only — the camera stays advisory (never
opens, never traps). Camera-less sites keep the radar-only gate; a faulty
camera is dropped via the existing bypassPresenceCamera admin toggle.
2. Cooldown as a REAL backstop behind presence: the presence branch returned
early, so entryCooldownSec was dead wherever a loop was wired. Now it bounds
the stationary-car double-ticket (a motion radar drops a motionless car →
spurious loop-clear re-arms one-car-one-ticket → same car reprints).
3. Post-hoc duplicate-plate anomaly (entry-side twin of plateSwapSuspected):
when entry ANPR recognizes a plate already OPEN under another session entered
within ENTRY_DUP_PLATE_WINDOW_MIN (default 15 min), sign ONE
entry.duplicatePlate anomaly naming both tickets for the operator to void.
ANPR stays non-blocking (rides the post-open snapshot as before).
REJECTED: camera-vetoed re-arm (defer re-arm until the lane flips free). The
camera has no leave events — "free" is a ~30s silence timeout that never lapses
inside a queue, so every queued car after the first would be suppressed until
an operator intervened. Blocking legit entry at peak beats nothing; the proper
preventive fix is a pass-through sensor (passedInput) — recorded as open in
wiki/concepts/entry-double-press.md.
Also: setup.relayTest reason was missing from both web catalogs (parity is only
enforced sq<->en, so the build passed) — added.
Tests: entry-press-gate.test.ts (blink suppresses / solid prints / camera-less
unaffected / bypass honored / cooldown catches the dropout re-press / residual
risk documented / still-present re-press stays suppressed) +
entry-duplicate-plate.test.ts (flags open dup, ignores closed/stale/self/other
plates). Suite 258 green.
