Two independent wiki updates bundled (all docs):
1. dingtian-dt008-reader.md: phantom optical decodes on the park-buzi EXIT
reader (empty pre-opening site, low-sun afternoons). Chain of evidence:
READ log lines carry the reader's own serial (H05MA5B0) → physical device,
not a network source; snapshot shows nobody present; code shapes are the
giveaway (6-digit numerics = checksum-less Interleaved 2-of-5, lone "C" =
Code39/Codabar artifact) → 1D engine decoding sun-made stripe patterns
(striped arm, fence shadows, glare). No fraud exposure (11-digit Luhn ids
can't match); noise only. Fix on the entity page: vendor-tool symbology cut
to QR+Code128 + min decode length, BOTH readers; config lives ON the device
→ re-apply after any factory reset/swap. Deliberately NOT filtering
impossible codes server-side — probe recording is the anomaly path's job.
2. Backfilled two shipped-but-undocumented features (six code files already
linked the first page as if it existed):
- concepts/entry-presence-bypass.md — admin drops a FAULTY presence signal
(granular radar/camera by decision, not a master switch); every flip is a
signed config_change; persists till off; tickets stamped presenceBypassed;
radar-bypass cooldown tradeoff; "the admin is not the adversary, but
trusted never means invisible".
- concepts/setup-relay-test.md — admin-only commissioning pulse, signed
barrier_open_command BEFORE the fire so a test open never reads as the
out-of-band-open fraud signal; saved controllers/declared relays only;
radarAlert lamps excluded; pulseOpen only.
