julian 43c1f45e29 feat(reader): channel tagging (clone defense) + structural filter for phantom scans
Build desktop / desktop (push) Successful in 4m12s
Build & push images / images (push) Successful in 2m52s
CI / check (push) Successful in 42s
Two reader-hardening changes born from the park-buzi phantom-scan investigation
(empty pre-opening site, exit reader pushing sun-decoded garbage codes).

1. CHANNEL TAGGING — closes the printed-card-clone hole. The DT-008 push is
   channel-blind (one opaque cardid from either engine) and SubscriptionFlow
   matched by value only, so printing an RF card's UID (often written on the
   card face, e.g. 86A158) as a barcode cloned the card. Now:
   - Vendor tool sets output prefixes (QRCode "Q:", Card "K:"; server env
     overrides READER_QR_PREFIX / READER_CARD_PREFIX).
   - routes/qr-reader.ts strips the prefix and tags the read's confirmed
     channel (DeviceReadEvent.channel optical|rf; kind qr|card). Enrollment
     capture stores the BARE value. READ log lines carry ch=… (permanent
     phantom attribution).
   - SubscriptionFlow.match requires channel agreement: an optical decode may
     not claim an rf credential (and vice versa) — refused + signed
     sub.refused.channelMismatch anomaly (a clone attempt is a fraud signal).
   - Unprefixed reads keep the legacy untagged shape and match as before, so
     enforcement only bites where prefixes are deployed. Deploy server FIRST,
     then set prefixes in the vendor tool.

2. STRUCTURAL FILTER — phantom decodes out of the signed feed (operator-
   requested, reverses the earlier "record every probe" position — red
   "who is exiting?" rows for NOBODY train the operator to ignore the feed).
   read-dispatch.ts drops a no-match reader value that cannot possibly be a
   credential we issue (no ticket Luhn shape, no SUB-/SUBSESS- prefix, not
   confirmed-RF, not a plate) to UNSIGNED device_events telemetry
   (unrecognizedRead:true). Deliberately WIDE plausibility: forged ticket
   shapes, unknown physical cards, unknown SUB- codes all still sign the
   normal refusal anomaly; enrolled credentials match before the filter and
   can never be hidden. Works for legacy unprefixed reads too — the feed
   cleans up on deploy, before any vendor-tool change.

Wiki: dingtian-dt008-reader.md records the clone hole + fix, the filter (as a
recorded position reversal), and the two device-side settings now part of the
credential contract (output prefixes + Card Input format, moving 6H→8H at the
next vendor-tool session; both live ON the device — re-apply after any
factory reset/swap).

Tests: qr-reader-channel.test.ts (prefix split, route tagging, bare-value
capture), subscription-channel.test.ts (channel agreement matrix + anomaly),
read-dispatch-filter.test.ts (filter boundary: phantoms dropped, probes kept,
enrolled never hidden). Suite 278 green.

julian 35e593ab63 docs(wiki): DT-008 phantom-scan diagnosis + backfill bypass/relay-test concept pages
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.
   Cross-linked from operator-issued-entry.md, cataloged in index.md, logged.

julian f6e35bbebf fix(reader): correct the QR reader's identity — Dingtian DT-008, not "GEE"
Build desktop / desktop (push) Successful in 4m16s
Build & push images / images (push) Successful in 2m46s
CI / check (push) Successful in 38s
An early wrong assumption named the QR/RFID access reader "GEE" /
"GEE/Fondvision" / "GEE-QR-ER80" (and summarized a raw GEE PDF as its
datasheet). There is no GEE device — it's the Dingtian DT-008
(dingtian-tech.com/en_us/qr_code_reader.html), the same vendor as the relay
board, which is why it integrates the identical HTTP-GET-push way.

Code:
- Driver symbol geeQrReaderDriver → dingtianQrReaderDriver; label →
  "Dingtian DT-008 QR/RFID reader (HTTP push)"; comments/description rewritten
  to the real DT-008 facts (Wiegand 26/34, TCP/IP, USB, RS485 — not RS-232;
  QR/barcode + ID/IC/NFC — not DataMatrix/1D).
- Persisted driverId "gee-qr-reader" → "dingtian-qr-reader" (the registry
  lookup key + the row created on assign in qr-reader.ts).
- Migration 0015 rewrites existing devices.driver_id rows so configured readers
  keep resolving (applied to the dev DB — 2 rows; the booth applies it on boot).
  Behaviour is unchanged: naming + the persisted id only.

Wiki + memory:
- Renamed entities/gee-qr-er80.md → dingtian-dt008-reader.md and
  sources/gee-qr-er80.md → dingtian-dt008.md; rewrote both to the real DT-008
  product-page specs while KEEPING all the verified-on-hardware protocol facts
  (cjihao serial, .jsp path, Connection: close). Fixed every cross-reference +
  "GEE" mention in 6 other pages. Memory gee-reader-serial-binding →
  dingtian-reader-serial-binding. The only surviving "GEE" mentions are
  deliberate naming-correction notes, the raw PDF filename, and the
  append-only log history.

Full workspace build/lint/test green; dev DB readers verified resolving to the
registered dingtian-qr-reader driver.
