Bring three queryable pages current with the booth-UX commit (cce99aa) whose
breadth hadn't propagated:
- booth-console: Active Sessions as a real table, dropped status column/filter,
inline live-feed rows, removed TARGE via-badge + redundant Direction filter,
plate now searchable + backfilled via plate-recognized WS push, per-user font scale.
- shift: Z-report display simplified (shitje dropped, opening cash added) while
the signed payload is untouched.
- i18n: users.font_scale recorded alongside language/theme as the matching
per-user server-stored pref (migration 0014).

The two failing apps/vision smoke tests assumed stub mode but the local .env sets
VISION_RECOGNIZER=fast_alpr (real-model work, 2026-06-19), so the app built the real
recognizer: /health reported "fast_alpr" not "stub", and /analyze on garbage bytes
422'd (real decode reject) instead of returning the empty stub contract.
Fix is test isolation: a conftest autouse fixture pins VISION_RECOGNIZER=stub for the
session (an OS env var overrides the .env in pydantic-settings), restoring it after.
vision 7/7.
Updates wiki/concepts/booth-console.md (the "no automated tests" Open note now reflects
the coverage that landed) and appends wiki/log.md.
Full workspace: shared 87, server 75, devices 18, web 17, vision 7 = 204 tests across
8 turbo test tasks, 0 failures; build/lint 14/14.

A barcode/QR scanner is an HID "keyboard wedge" — it types the id + Enter into
whatever holds focus. Previously that only worked while the ticket <input> was
focused; a scan with focus elsewhere (or nowhere) went nowhere.
New useScanner hook (apps/web/src/lib/use-scanner.ts): a document-level keydown
listener that detects the scanner's FAST keystroke burst ended by Enter and opens
the pay/exit modal via setActiveTicket — regardless of focus. A gap > 50ms resets
the buffer, so human-paced typing with nothing focused never registers as a scan
(min length 3 guards stray Enters). Keystrokes into an input/textarea/select/
contenteditable are ignored, so the manual ticket field still works by hand. The
hook is paused while a modal is already open — a scan must not abandon an
in-progress payment; the operator finishes/closes, then scans the next car.
Verified at runtime (Playwright): a fast burst with focus on BODY opens the modal;
a second scan while the modal is open is ignored; slow (120ms) human typing does
NOT open it; the manual input submit still opens it. build+lint 14/14.

Three booth-integrity improvements that share the entry/exit flows and activity log.
Refusal snapshots: previously only an accepted open captured a camera image; now
every refusal/hold anomaly fires the directional camera too (a turned-away car is
exactly the evidence wanted) — entry refused-full/held, exit refused
closed/no-session/unpaid/grace-expired (booth + reader paths), refused subscription.
A refused entry has no ticket id, so a synthetic REFUSED- ref keys the anomaly + photo
together. Same fire-and-forget contract; failed captures still show as tiles.
Subscriber access medium: the subscription flow already signed `via`
(qr|card|plate) into entry/exit payloads; surface it as a typed LedgerPayload.via, a
cyan chip in the ticker, and an "Entry medium" modal row (sq+en). Display-only.
One car = one ticket: the entry button could be mashed to mint many tickets per car
(corrupting occupancy + enabling ticket-shopping at exit) — the old #inFlight guard
only blocked overlapping presses. Add a per-relay guard configured on the relay spec:
PRESENCE mode (presenceInput ties ticketing to a vehicle loop on a Dingtian input —
one ticket per car, re-armed when the loop clears) or COOLDOWN fallback
(entryCooldownSec) when there's no barrier feedback. A suppressed press is unsigned
device_events telemetry, not a signed anomaly. SetupWizard exposes both fields.
Fail-closed entry and barrier-is-not-a-door invariants untouched; guard state is
in-memory/rebuildable, starts armed after restart.
Wiki: new entry-double-press; updated entry-exit-points, booth-console, index.

Linked Claude Design project "TRM — Tracking & Race Management" is a
race-timing kit, not a parking design. Adopted its TOKENS only — no TRM
components. Aligned the existing term-* accents onto TRM's exact night/
semantic values (surfaces → night scale; amber→#f2a516, green→#2e8c4a,
red→#e8412b flag, cyan→#2563c8 blue) so the whole booth UI shifts palette
with zero component edits. Exposed TRM's full vocabulary (night/ink/paper
scales, flag/amber/green/blue, viz-1..8, 4px spacing, type scale, square
radii, sharp offset shadows) as Tailwind v4 utilities for new work.
Offline appliance: dropped TRM's Google-Fonts @import (no runtime network);
Goldplay display face not self-hosted yet — falls back to a sans stack.
Web build green; login renders on the new palette.

Generalise printer-only monitoring to every configured device. New
DeviceMonitor polls all enabled devices each tick (default 8s): printers
via rich readStatus(), relays/readers/cameras via the generic healthCheck()
reachability probe, flattened to one traffic-light (ready/degraded/offline)
+ detail, deduped (emit on change only), fail-toward-offline.
- device-status bus event + GET /api/devices/status snapshot.
- Pushed over the existing /api/ws (hello carries the initial set;
device-status frame per change).
- Web: live-store devices map, WS handler, DeviceFooter chip-per-device
(role label not vendor; click a degraded/offline chip for an issues panel).
Verified roleKind resolution + change-only emit on a fresh DB.
Note: the footer's UI surface (api type, router mount, i18n devices) rides
in the subsequent subscription commit due to shared-file overlap.

A shift becomes a SITE-WIDE accountability period — at most one open at a
time — so every taking is unambiguously attributed to one operator. Login
stays decoupled from shifts (an operator can log in off-shift to review).
Backend:
- ShiftService.currentOpenShift()/requireOpenShift(); open() refuses when ANY
shift is open and throws ShiftAlreadyOpenError{heldBy} (self vs. other).
- requireShift preHandler gates /api/pay, /api/exit, /api/voucher,
/api/barrier/reopen → 409 {code:"no_shift"}; read-only lookups stay open.
- GET /api/shift/current returns site-wide {open:{startedAt,operator},isMine}.
- GET /api/events?since=<iso> for per-shift log scoping (db: re-export gte).
Frontend:
- Header shift button: open / close-mine / disabled-when-another-holds-it.
- Pay/exit modal gate banner (one-click open; "held by X" when another's);
pay/exit/voucher disabled until this operator's shift is open.
- Active-Sessions barrier re-open gated the same way.
- Live feed scoped to the open shift's window; shared useShift() Query
invalidated over the WS on shift_open/shift_z_report/cash_movement.
- sq/en strings for the control + gate.
Wiki: shift.md (site-wide single-open + gate; superseded per-operator note),
booth-console.md (header control + gate), log entry.
Verified: site-wide invariant + heldBy + handover + chain integrity on a
fresh migrated DB (11/11); db/server/web build clean.
File concept pages for the operator-UI architecture ([[booth-console]]: stack,
/api/ws live feed, anti-CSWSH) and [[i18n]] (per-user server-stored language;
resolves a dangling code-comment link). Qualify the stale 'plain React' note on
react-vite-spa. Backfill log entries for the live WebSocket, frontend foundation,
and i18n builds (which had none), plus a reconciliation lint entry. Catalog
booth-exit-flow + the two new pages in index; fix the concept count (27→41).
