julian e67f0ccef0 feat(carwash): review outbox, booth side — plate-blurred vehicle crop + the operator's choice, queued for a trusted remote reviewer
The operator's category choice is a hypothesis, not truth (user, 2026-09-06): each wash
order with a vehicle read queues a package for a trusted reviewer over the private overlay
(Netbird); the verdict becomes the phase-B training label and the per-operator error rate.
wiki/concepts/vision-review-outbox.md.

- Boxes: the vision service returns the vehicle bbox; snapshot.ts stores the vehicle and
  plate boxes on the read as FRACTIONS of the analysed frame (the stored snapshot is a
  downscaled copy); vehicleForIdentity() returns them.
- carwash_review_outbox (migration 0031) + review-outbox.ts: crop = detector box + 8 %
  margin, ≤ 640 px, plate blurred in place from the plate box; payload carries a
  pseudonymous booth id and a keyed operator hash — no site name, no plate, no OSD, no
  bystanders; multipart POST with a per-booth bearer; 2xx → sent (image dropped);
  400/404/413/415/422 → abandoned; anything else → backoff 1 min·2^n capped 6 h; voided
  orders and items older than 14 days abandoned unsent. Nothing queued while unconfigured.
- Enqueue is fire-and-forget off the intake path in createOrder; the loop runs every
  CARWASH_REVIEW_INTERVAL_SEC (60) and stops on close.
- GET /api/carwash/review/status (site:read) + a "Remote review" line in Setup → Car wash.
- Env CARWASH_REVIEW_URL / _TOKEN / _BOOTH_ID (all three or off) documented in
  .env.example and forwarded by compose.
- Tests: review-outbox.test.ts (crop + blur on a synthetic frame, config/pseudonyms,
  queue/drain/backoff/abandon, through the app). Wiki: new concept page, index,
  venue-modules As built, log. The collector is not built.

julian 5e1395db18 feat(carwash): advisory vehicle category from the entry camera — mapping, pre-select, downgrade flag
The app plumbing for venue-modules.md §"Vehicle category from vision"; the model is the
open half (no bundled recognizer emits body_type yet, so the desk shows nothing until
phase A lands in the vision service).

- Shared: VEHICLE_CLASSES vocabulary, VehicleRead, CARWASH_VISION_THRESHOLD_DEFAULT,
  reason code carwash.categoryDowngrade; settings/order/lookup views carry the read.
- Vision contract: /analyze vehicle.body_type + confidence (service schema); the Node
  client normalises to the vocabulary and drops the rest.
- Record: snapshot.ts stores the read in the plate's device_events row (or its own when
  the plate was unreadable); vehicleForIdentity() resolves it like the plate.
- Car wash: carwash_categories.vision_classes (site mapping "car, sedan → Vetura"),
  carwash_config.vision_threshold (signed config_change when it moves), four vision
  columns on orders — migration 0030. Lookup returns vision + suggestedCategoryId.
- Desk pre-selects the mapped category and shows the read + snapshot thumbnail; Setup
  offers class chips per category and the threshold. Operator decides.
- Flag: a read at/above the threshold whose mapped category prices HIGHER than the chosen
  one signs one `anomaly` (both categories/prices, operator, snapshot) and stores its id on
  the order. Equal/upgrade/unsure/unmapped → nothing. Recorded only, never blocks, no
  reason prompt (user, 2026-09-06).

Tests in carwash.test.ts; wiki venue-modules (As built), opencv-anpr-service, log.

julian 50c18405b6 feat(roles): roles remember the jobs they follow (re-appliable), every role edit is signed
Closes the permissions-matrix loose ends (venue-modules.md §Permissions matrix):

- `role_jobs` (migration 0029): a role stores the manifest jobs it was composed from
  (chips on at save + any bundle fully present). `jobById` / `jobsBehind` in
  @parking/shared surface a followed job whose bundle grew past the role in a later
  release; the roles list shows a "behind <job>" badge with a one-click "Update to job"
  (the union, nothing removed) and the editor lints it. Never a runtime union: the grid
  stays the explicit enforcement layer and an update never widens a role without a click.
- Every role create/update/delete appends a `config_change` (`role.<id>`, prev/value =
  name + sorted permissions + jobs, operator); a no-op resave signs nothing. roleRoutes
  now takes the ledger.
- booth-supervisor already carries subscription:*; the stale open note is closed.

Tests: routes/roles.test.ts. Wiki: venue-modules status, local-jwt-auth, log.

julian e14e31a840 feat(tills): per-till activity log, wash bucket on the booth Z-report, wash-desk printer role
Closes the three known follow-ups of the Tills decision (venue-modules.md):

- Activity log per till: `tillOfEvent(type, payload)` in @parking/shared (money events
  by payload till, other events by their owning module's till, everything else booth),
  applied by `/api/events?till=` in SQL and passed by the hub log, the Drawer "today"
  panel and the booth feed (history + live pushes). The events route admits a role that
  holds a module feed permission without event:read and returns only that module's
  event types — the live-socket rule.
- Booth Z-report: `chargesByModuleMinor` sums the chargeLines on the till's payments by
  module; the ticket bucket excludes them (Bileta = parking only); printed
  "Lavazh (në biletë)" only when any was taken. The wash till's slip prints "Lavazh:".
- Printer role `wash-desk`: the wash till's Z-report and vouchers print there, falling
  back to the booth printer; nothing falls back to the desk. `printerRoleOf()` is the
  one reading of the role field (the entry/booth loaders treated any non-booth role as
  an entry dispenser). Footer label "at wash desk".

Also: `GET /api/carwash/settings` opens to carwash:read OR site:read (new
requireAnyPermission) — the Wash operator job could not load the desk's category and
service pickers. Tests for all four; wiki (shift, printer-roles-failover, venue-modules,
log) updated.

julian 55d6242c7d feat(permissions): per-desk till guards, jobs in the role composer, permission-scoped live feed; role reassignment applies without re-login
CI / check (push) Successful in 46s
Build & push images / images (push) Successful in 2m58s
Build desktop / desktop (push) Successful in 4m53s
Permissions matrix rethink (wiki/decisions/venue-modules.md §"Permissions matrix",
open-questions #16) — the grid stays the enforcement layer:

- Move 1: each desk's money is guarded by that desk's own permissions. Manifest
  tillGuards {read, shift, cash}: booth = shift:read / shift:create / drawer:create
  (unchanged), carwash = carwash:read / carwash:cash (new). Shift + drawer routes
  resolve the guard FROM THE TILL (requireTill); a wash role holds no shift:* and cannot
  touch the booth by construction. Replaces the session:read borrowing (tillPermission).
  /api/shift/tills lists the role's readable tills with canWork; history/movements
  without a till filter return the union of readable tills.
- Move 2: jobs — manifest permission bundles (booth-operator, booth-supervisor,
  merchant, wash-operator) as one-click chips in Setup → Roles, with "mixes desks" and
  "partial job" lints (warnings, never blocks).
- Move 3: the live WebSocket admits any watch permission (event/session/device read or
  a module's feedPermission) and filters every push per role; report:read is the
  reports screen only.

Auth: the token's roleId is only a hint — refreshRole() after every jwtVerify resolves
the user's CURRENT role (cached, bumped on role/user writes), so reassigning a user's
role applies on the next request and a deleted user's session ends with 401.

Tests: till guards + look-only role, feed rules, every job's permissions exist, role
reassignment without re-login. 353/353.

julian a9ccf9e20c feat(carwash): Car Wash v1 + per-till shifts + site-level pay-at + till access by module permission
Car Wash — the pilot venue module (wiki/decisions/venue-modules.md):
- Master data (categories × services price matrix) at /setup/carwash; the desk at /wash
  (ticket lookup → order; open queue oldest-first: Done / Paid cash / Paid card / Void;
  Finished list). Orders freeze names + price; their life is signed (carwash_order,
  carwash_payment). Migration 0027.
- Where money is taken is a SITE setting (carwash_config.pay_at, migration 0028, signed
  config_change on a flip) — no per-order radio; a stale client is refused (409).
- Core seams: PayStation charge providers (a booth-paid wash rides the parking payment as
  chargeLines) + applyValidation() shared with the merchant route. A bay-paid, done wash
  signs the $0 parking payment so the exit reader releases the car.
- "Parking discount" modes for the wash: free while the wash runs (+ tolerance) and wash
  price off the fee (floored at 0), resolved at done and anchored at the order's intake
  (the entry-anchored version comped a 74-day stay); typed-amount and percent hidden for
  the wash. Long durations render y/d/h/m.

Tills — a shift belongs to a till, not the site (wiki/concepts/shift.md §Tills):
- TillId booth|carwash; every money event names its till (absent = booth, so the chain
  re-folds identically). ShiftService is per till: single-open, folds, X/Z-reports,
  vouchers, carry-forward. A bay payment needs the carwash shift.
- Working a till needs that till's module permission (manifest tillPermission; 403
  till_forbidden); /api/shift/tills lists only the role's tills.
- Web: ShiftButton per till (header = booth, wash desk = carwash); shift hub lists every
  open shift with till badges + filter; drawer hub switches tills.

Modules: landing per module (index route resolves booth → module landing → shifts →
profile); guards bounce to "/", /booth needs session:read.

Tests: carwash e2e suite (settings, intake, booth/bay paths, modes, void, gate, pay-at
policy, till permissions), 6 per-till shift tests; suite green (1 pre-existing flaky
backup test under the parallel run).

julian 23d6379be8 feat(modules): venue-module registry — entitled ∩ activated, requireModule, Setup panel
Groundwork for the Car Wash pilot (wiki/decisions/venue-modules.md, build-order
steps 1 + 3). No Car Wash code yet; validation is the first module behind the
seam, unchanged in behaviour.

- @parking/shared: MODULE_IDS, ModuleManifest, MODULES (parking required;
  validation dependsOn parking), parseEntitledModules / resolveModuleActivation
  / effectiveModules as pure functions.
- DB: site_config.modules_json (migration 0026, hand-written + journal;
  additive, nullable = everything entitled).
- Server: modules.ts (entitledModules from MODULES_ENTITLED env, activated
  from site_config, effective set, requireModule preHandler → 403
  module_disabled); modules/index.ts registers folder-based modules by
  iterating the registry (modules/validation); site-config GET exposes
  modules/modulesEntitled/modulesActivated, PUT takes the full desired set,
  enforces entitlement + dependency rules (400 with reason) and signs one
  config_change per module that actually flips; /api/auth/me carries the
  effective set; validation routes guarded requireModule → requirePermission.
- Web: lib/modules.ts + modules/{index,validation}; router.tsx spreads
  WEB_MODULES into nav + route tree (validate route no longer named there);
  Setup → Site "Modules" panel (required shown disabled, dependencies as
  hints, server refusal shown verbatim); validation sections + programs fetch
  gated on the module; App invalidates the router whenever the session
  changes (route-context consumers only re-read on navigation — the nav was
  stale after a flip, and after every other setUser too).
- Lavazh validation station retired (STATIONS = ["bar"]; rows untouched).
- Deploy: MODULES_ENTITLED=parking,validation explicit in both booth stacks;
  documented in .env.example.
- Tests: modules.test.ts (7); suite 329/329; web build clean; Playwright
  round-trip on /setup/site verified live.

julian 2910672b5a fix(backup): persist last-success/error status; wall-clock-based schedule
BackupService tracked last-success/last-error as plain in-process fields
and scheduled the daily backup via setInterval measured from process
start — so any server restart (deploy/crash/OOM/reboot, routine under
`restart: always`) silently reset the admin UI to "last successful
backup: Never" and drifted the actual cadence, independent of whether
backups were writing correctly to disk (they were — a real field
incident at park-buzi showed 7 valid rotating backups on disk with the
status stuck on "Never").

Persist last-success/error to new site_config columns (migration 0025)
and add BackupService.isDue(), computed from the persisted timestamp
instead of process uptime; server.ts now polls every 15 min and lets
isDue() gate the actual run. No API/UI contract change.

julian 692dff5f89 feat(validations): merchant (bar/lavazh) ticket validations end-to-end
In-park merchants discharge customers' parking: a merchant user scans the
ticket on their device (/validate; validation:create + program↔user binding)
and applies their program — comp / first-N-minutes free / amount-off (capped,
typed at scan) / percent. All money stays at the booth: the quote folds live
validations in a canonical order (timeCredit → percent → fixed → comp, net
floors at 0, Σ lines ≡ gross − net), the payment records gross/discount and
CONSUMES the validation ids (an overstay's fresh period never re-applies
them), the receipt prints the gross → lines → net story, and the Z/X-report
carries discountTotalMinor leakage. Every apply/void is a signed, attributed
ledger event (refId = append-only void); program config is /setup/site master
data (Bar/Lavazh checkboxes + right-column panel, tabs when both) whose saves
sign config_change. Migration 0024 + reset-db drift-guard entries; 8 route
integration tests + priceSession fold suite.

julian ba5b4b1f4e fix(reset-db): app_logs + tariff_drafts were uncategorized — add a drift guard
Both tables belonged to NO reset category and silently survived every
reset, --all included (the hand-maintained table list lagged the schema
twice). app_logs gets a new --diagnostics category; tariff_drafts joins
--config. A drift guard now compares the category union against
sqlite_master before doing anything and refuses on any uncategorized
table, so the next new table forces a deliberate one-line decision instead
of escaping by omission. Verified on a scratch DB: guard refuses a planted
table (exit 1), --all lists both new tables, --diagnostics wipes app_logs.

julian 6ceaadfbf2 feat(devices): camera clock sync via ISAPI — heal the 1970 power-cut reset
Build desktop / desktop (push) Successful in 4m18s
CI / check (push) Successful in 44s
Build & push images / images (push) Successful in 2m51s
park-buzi field observation: after a power cut the Hikvision cameras
reboot at the 1970 epoch (no/dead RTC battery, no NTP) and stay there
until a human logs into the web UI (which silently pushes the browser
clock) — corrupting the snapshot OSD timestamps (the evidence trail) and
ANPR push times meanwhile.

The host is the site's time authority (offline-first, no NTP infra):

- Device monitor triggers a sync at each camera's offline→ready edge —
  exactly the power-restored moment — plus a 24h backstop; the attempt
  is stamped before the async call so a failing camera retries at
  backstop cadence, never every poll.
- HikvisionCamera.syncClock: GET /ISAPI/System/time; drift ≤60s → leave
  alone; beyond (or unparseable = infinite drift) → PUT timeMode=manual
  with the site wall-clock now WITH explicit utc offset
  (localIsoWithOffset), echoing the camera's timeZone verbatim — correct
  the clock, never fight its tz/DST config.
- Jumps >1h (the power-cut signature) log warn (persisted to app_logs);
  small corrections info. Capability-guarded (isClockSyncable) —
  hikvision only; dahua's CGI has no such endpoint.
- http-digest generalised to digestRequest (GET/PUT/POST + body); the
  handshake was already method-aware. digestGet delegates unchanged.

8 new tests: in-sync no-op, 1970 PUT shape (manual + host instant +
echoed tz), unparseable→sync, failed-set surfaces, dahua non-capability,
DST-both-sides pins on the offset formatter.

julian cd3b534e51 feat(setup): USB printer discovery — pick a real /dev/usb device
Build desktop / desktop (push) Successful in 4m21s
CI / check (push) Successful in 50s
Build & push images / images (push) Successful in 2m54s
The kernel numbers usblp nodes by plug/boot order (park-buzi's printer
is lp1); the wizard hardcoded lp0 in labels/default and the admin had to
shell in and `ls /dev/usb`. Now:

- GET /api/setup/usb-printers enumerates /dev/usb/lpN (visible via the
  compose bind-mount) and enriches each with the printer's self-reported
  make/model from sysfs ieee1284_id (readable through Docker's ro /sys).
- The wizard's devicePath becomes a SELECT of printers actually present
  ("/dev/usb/lp1 — Xprinter XP-K200L"): a fresh form preselects the
  first real device; a saved-but-unplugged path stays selectable,
  flagged "saved — not present now"; zero found falls back to free text
  + a check-the-cable hint.
- Transport option label no longer hardcodes lp0.

Wiki: printer-usb-transport marked HARDWARE-VERIFIED (lab 2026-07-07:
full slip + feed + cut over USB — parity with TCP).

julian 011fe5a4c4 fix(devices): USB truncation mode 2 — close() kills the in-flight usblp URB
Build desktop / desktop (push) Successful in 4m16s
CI / check (push) Successful in 43s
Build & push images / images (push) Successful in 2m51s
The chunked-write fix (81bc2e3) still truncated on hardware: the lab
test slip stopped mid-sentence with no feed and no cut (text hidden
until the feed button). Verified against drivers/usb/class/usblp.c:

- write() returns at URB SUBMISSION, not completion;
- only ONE write URB is in flight (the next write EAGAINs until it
  completes);
- usblp_release() — our close() — KILLS in-flight URBs.

The printer drains bulk data at PRINT speed (tiny internal buffer on
these clones), so closing right after the last accepted write cancels
the still-transferring tail — exactly where the feed + GS V cut bytes
live. Kernel-accepted ≠ printer-received.

Fix: the one-URB rule makes acceptance of write N a completion
certificate for write N−1. writeAllUsb now writes the payload's FINAL
BYTE alone — its acceptance proves everything before it is physically
in the printer — then drains 300 ms for that single packet before the
caller closes. New test pins the final-byte-alone chunking; wiki
printer-usb-transport.md carries the kernel-level account.

julian 7649b897c4 feat(tariff): lab explains the sum — fee breakdown from the engine walk
"ALL 740 / 3h 2m" gave no derivation. explainFee in @parking/shared runs
the EXACT computeFee walk with an optional trace collector — one code
path, so Σ line items ≡ the amount by construction (golden V1 regression
byte-identical; instrumentation changes no fee). Items: contiguous
same-price increment runs (time window · N × unit · tier-card name),
window-package occurrences, stepped day totals (top-tier repeat
flagged), daily-cap clamps as NEGATIVE adjustments, entry grace.

/api/tariff/simulate returns `breakdown` (null when settled); the lab's
Outcome panel renders the lined table with a rounding note (raw min →
billed min at the increment — answers "why does 3h 2m bill as 4h") and
a total row. Works against active/historical versions and drafts alike,
so a night-package draft can be verified line by line before publish.
Largely delivers the wiki's open "composer price preview" item.

4 new engine tests pin the sum invariant + item shapes (97 shared green).

julian fcea992e1e refactor(devices): rename driver "cashino" → "escpos" (generic ESC/POS)
The reachability-only clone driver carried its first unit's vendor name,
which read as misleading in the setup UI once other clones (ICS/Xprinter
XP-K200L, verified 2026-07-06: no /prn_stat.htm) used it. It was always
the generic ESC/POS driver — now named so:

- printer-cashino.ts → printer-generic.ts; GenericEscposPrinter;
  id "escpos", label "Generic ESC/POS 80mm printer (Cashino,
  ICS/Xprinter…)".
- Migration 0023 rewrites stored devices.driver_id rows.
- The registry keeps a PERMANENT cashino→escpos alias so restored
  pre-rename backups still resolve instead of "unknown driver".

Prose mentions of the Cashino as physical hardware stay — it's a real,
verified-fit printer; only the driver identity stopped being vendor-named.

julian 81bc2e357c fix(devices): USB printing dropped the job tail — chunked write loop
Field bug (ICS XP-K200L over USB): text printed, barcode + cut missing;
same bytes over TCP fine. sendRawUsb did ONE write() on an O_NONBLOCK
usblp fd and never checked bytesWritten — the kernel accepts only what
fits the printer's ~8 KB USB buffer and returns a short write, so the
tail of any job bigger than one buffer (the barcode mid-payload, the cut
at the end) was silently discarded. The regular-file test stand-in can't
short-write, which is why tests never caught it.

writeAllUsb now pushes 4 KB chunks until every byte is accepted,
continues after partial writes, retries EAGAIN/zero-byte with a short
pause, and fails at the deadline with an (N/M bytes) diagnostic. Driven
by fake-handle tests (short writes, EAGAIN interleave, wedged-printer
timeout, non-EAGAIN passthrough).

julian 7ef332999e feat(reports): occupancy curve, hour×dow heatmap, stay histogram, fraud KPIs
The dashboard had generic BI views but nothing parking-shaped. Added:

- Occupancy step-area over the range with the configured capacity as a
  red reference line. occupancyStart folds the ENTIRE prior ledger
  (voided entries excluded, clamped ≥0); each series point carries
  occupancyEnd. Answers "when are we near full".
- Entries heatmap hour × day-of-week (7×24, row 0 = Monday, site tz) as
  a pure CSS-grid intensity map — weekday-vs-weekend at a glance, the
  direct evidence for tariff windows. Replaces the flat hour histogram
  (strictly contains it).
- Stay-duration histogram at tariff-shaped edges (30m/1h/2h/4h/8h/24h/
  tail): where ladder/up-to breakpoints should sit.
- Voids + anomalies KPIs (accented when >0) — the look-closer counters
  the signed chain exists for; peak-occupancy KPI (peak / capacity).
- Revenue bars stacked cash vs card (the drawer's money vs the bank's);
  CSV export gains cash, card, occupancy_end columns.

Internals: localParts caches its Intl formatter per tz (was one new
formatter per ledger row); @parking/db re-exports lt/gt. 5 new tests.

The device monitor logs + re-emits a status only when state OR detail
changes, but the camera probe's detail was the exact snapshot byte count,
which differs on every JPEG frame — so healthy cameras "changed" on
nearly every poll, writing a log line + websocket event each time

stable power-of-two bucket ("snapshot ≈16 KB" / "≈256 KB") that moves

julian fd9885e9ec feat(tariff-lab): DB-backed draft tariffs + named published versions
Experimenting used to mean publishing — churning the immutable version
history and risking real tickets pricing against a half-baked card while
the admin iterated. The lab is now a true sandbox:

- tariff_drafts table (migration 0021): MUTABLE by design — the one
  exception to "editing publishes a version"; a draft prices nothing and
  signs nothing. Drafts are validated + tz-stamped on save exactly like a
  publish, so a saved draft always simulates and never fails at publish.
- CRUD under /api/tariff/drafts (list tariff:read, mutations
  tariff:update); publishing a draft goes through the normal immutable
  POST /api/tariff/versions path.
- Lab UI rebuilt: sidebar lists lab drafts AND the full published history
  (click any to price against it); main pane cut to pure entry/exit
  (ticket loader, payment, category inputs dropped); the composer form is
  extracted to TariffEditorForm.tsx and reused in a modal (new drafts
  prefill from the active card); per-draft Publish with confirm.
- tariff_versions.name (migration 0022): optional label stamped at
  publish — carried from the lab draft, or typed in the composer's new
  optional field — so history reads "Winter 2027", not UUID prefixes.
- Includes the composer UI + sq/en labels for the package mode (engine
  landed in d9e6c13) and the "Flat price / hour" relabel.

5 new server integration tests (RBAC, roundtrip, validation, tz-stamp +
simulate + publish w/ name); server suite 288 green.

julian d9e6c13831 feat(tariff): whole-window package pricing mode (packageMinor)
A windowed card can now charge ONE total for any presence in its window —
the real night rate ("20:00–07:00 = 400, leave earlier and it's still
400"), which the per-increment flatMinor could not express (park-buzi's
"night 400" card billed 400/HOUR). Engine charges once per contiguous run
of increments the card wins, tracked across rolling-day segments so a
night crossing the 24h boundary charges once; out-of-window increments
price by the base card as usual.

Operator decisions (2026-07-05): per-occurrence repeat (two nights = two
charges), any-touch-pays-full, windowed cards only (a base "price per
day" is a 1-row up-to table). Validator: mutually exclusive with
flat/blocks/steps, no per-card cap, forbidden on the defaultCard.
flatMinor docs clarified as PER INCREMENT. 6 new engine tests.

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 b4f1418858 fix(entry): enforce the camera press-gate + duplicate-ticket defenses
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.

julian 6505a4a73b feat(entry): admin bypass of the presence gate for faulty radar/camera
Build desktop / desktop (push) Successful in 4m12s
Build & push images / images (push) Successful in 2m50s
CI / check (push) Successful in 41s
The entry button (physical press AND the operator-issued mint) requires
radar/loop presence + camera detection to confirm a real vehicle. When one
of those devices is faulty, the gate blocks legitimate transient entry. Let
the ADMIN drop a specific signal as a requirement until support fixes the
hardware — the admin is not the adversary, but weakening an anti-fraud gate
stays attributed and auditable:

- Granular: bypass radar and camera independently (Setup → controller
  section). A dead camera drops only the camera check; a dead radar only
  radar. Both off = normal gate; both on = press-to-print.
- Signed: a DEDICATED endpoint (PUT /api/site-config/presence-bypass,
  site:update) appends a signed config_change {setting, value, prev,
  operator} per actually-changed signal — new ledger type. No-op toggles
  sign nothing; disabling signs too. Kept out of the generic site PUT.
- Flagged: every vehicle_entry issued (and every refusal anomaly) while
  bypassed carries presenceBypassed:[...] in its signed payload.
- Persists until turned off; amber warning in Setup while active. The
  booth entry light treats a bypassed signal as satisfied (server
  re-checks authoritatively). Physical-button path falls through to the
  cooldown backstop when radar is bypassed.
- Migration 0020: two boolean site_config columns (default off).

Fixes a latent bug surfaced by the tests: firstRelayByDirection returned no
presenceInput, so issueForOperator's radar gate always read "presence loop
unavailable" — operator-issue never actually gated on radar. The resolver
now attaches the presence input serving the relay (mirrors relayForButton).

10 new tests: 5 gate combinations (each bypass drops only its signal +
records it), 5 route tests (RBAC, signed transitions, no-op, validation).

julian 306d136a08 feat(setup): operator-tested relay pulse, signed into the ledger
Add a per-relay "Test" control on each saved controller in /setup so an admin
can prove barrier wiring without a vehicle. POST /api/setup/test-relay pulses a
barrier relay — but because a physical open with no matching signed command is
the fraud signal, the route SIGNS a barrier_open_command (reason setup.relayTest,
source manual, attributed to the acting admin) BEFORE it fires. Reconciliation
then reads the open as explained, not an anomaly, and there's an audit trail.

- Admin-only (site:update), CSRF-guarded; fires only against a SAVED controller
  (real id → clean attribution; also stops a redirected/unsaved config from
  opening an arbitrary host's barrier). Sign-before-fire; a pulse failure is
  reported, not a 500. radarAlert relays (lamps) are excluded from the UI.
- New reason code setup.relayTest in @parking/shared (+ EN template); sq/en keys.
- EventLog constructed before setupRoutes so the route can sign.
- Integration test (stub controller, no hardware): RBAC 403, CSRF 403, signed
  barrier_open_command on success, 400 unknown relay w/ no ledger row, 404
  unknown controller, 400 bad relay value.

julian 33c4ea1e91 feat(entry): operator-issued entry + exit plate-swap reconciliation
Build desktop / desktop (push) Successful in 4m29s
Build & push images / images (push) Successful in 2m51s
CI / check (push) Successful in 37s
Two halves of one anti-fraud design.

(A) Operator-issued entry — when the physical entry button is broken, an
operator can issue an entry ticket so a real car isn't blocked out of the lot.
This hands the operator-adversary a mint, so it is:
  - PRESENCE-GATED like the physical button: a real car must be present (radar/
    loop AND camera busy). Enforced BOTH sides — the server re-checks current
    presence so a direct POST can't bypass a disabled button; no presence loop
    => feature unavailable; a no-presence attempt signs an anomaly.
  - FLAGGED: vehicle_entry source=manual + operatorInitiated + operator, PLUS a
    companion entry.operatorIssued anomaly (the adversary path always leaves a
    red-flag row).
  - capacity-OVERRIDE allowed but stamped lotFull (a broken button mustn't trap
    a legit car).
  New session:create permission (migration 0019 -> operator role, admin-
  revocable), POST /api/entry/issue (open-shift gated), EntryFlow.
  issueForOperator; the fraud-critical print->sign->open->snapshot sequence is
  factored into one shared #issueTicket (button + operator). UI: the entry
  BarrierLight becomes a clickable issue-control when presence+permission+shift
  meet (confirm -> issue).

(B) Exit plate-swap reconciliation — defends the ticket-swap fraud the mint
enables (paid car let out on a fresh $0 ticket, original ticket lingers
"inside", occupancy drifts up by phantom cars). The plate is the invariant:
ExitFlow.#reconcilePlateAtExit compares the exiting plate against all OPEN
sessions' entry plates, EXACT + HIGH-CONFIDENCE only (>=0.85; a fuzzy read never
gates — ANPR is advisory). On a match under a DIFFERENT ticket:
  - BOOTH path: returns swap_suspected + signs exit.plateSwapSuspected; the
    pay/exit modal shows a red warning + "Override & release" (override signs an
    attributed exit.plateSwapOverride). Flag+override, never a silent hard block
    (exit fails-open; a plate is never the sole gate).
  - READER path (no operator): log-only anomaly + fail-open.
  Extended BoothExitResult + /api/exit (override); boothExit client returns a
  structured swap result.

Verified: full monorepo build/lint/test green (229 server tests incl. 4 new:
hold-on-swap, override-releases-with-attribution, low-confidence-no-warning,
own-plate-no-warning). New wiki: operator-issued-entry.md +
plate-reconciliation.md; cross-linked from entry-exit-points, capacity-
occupancy, index. Preserves "a plate never OPENS a barrier alone — and now never
TRAPS a car alone either."

julian 114a32e6f2 feat(drawer): operator records cash movements, admin reviews after (own /drawer route)
Rework drawer cash movements from synchronous admin-authorization-at-creation
(operator typed an admin's password inline for every receipt/disbursement) to
operator-records-freely -> admin-reviews-after.

- New `drawer` resource: drawer:create (operator records; admin-revocable per
  role) + drawer:review (admin authorizes/denies). Migration 0018 grants the
  default operator role drawer:create; admin gets all in code.
- New signed `cash_review` ledger event { refId, decision, reviewedBy, note? }.
  A DENIAL is a FLAG, not a reversal: it never appends reversing cash and never
  touches the drawer balance (the correction is settled outside the app). This
  is what keeps a late review from leaking into the next operator's inherited
  drawer — a denial that lands after the reviewed shift closed moves no cash.
  Regression test: op1 disburses -> closes -> op2 inherits -> admin denies ->
  op2 drawer unchanged.
- Move the feature OFF the polluted /shifts route to a top-level /drawer
  (operator: record + own; admin: review queue + all). routes/drawer.ts lifted
  from routes/shift.ts (retired the authorizer-password gate; kept shift:cash
  for its other job = admin-sees-all-shifts). New DrawerManager.tsx.

Display fixes bundled:
- Render cash_review in the event-detail modal (decision / reviewed-by / note /
  movement ref) — previously showed nothing.
- Relabel the shift drawer figures for clarity: Daily takings / Receipts /
  Disbursements (was Cash payments / Cash added / Cash removed).
- Hide the Card figure everywhere when CARD_PAYMENTS_ENABLED is false (no POS
  on-site), matching the card-tender gate.

shared/db/server/web all typecheck; 225 server tests pass (incl. the drawer
review + cross-shift-leak regression); web build + i18n parity green. Verified
end-to-end via Playwright. Recorded in wiki/concepts/shift.md.

julian d92b8d1e6a feat(db): gated training/demo database reset CLI
A site is sometimes run live to train operators/admins; afterwards the demo
data must go without an obvious self-serve button (the operator must not be
able to wipe history). Adds packages/db/scripts/reset-db.mjs, exposed as
`pnpm db:reset` (dev) and run via `docker exec ... node
node_modules/@parking/db/scripts/reset-db.mjs` on the booth (no pnpm there).

Category flags (combinable): --financial (ledger + telemetry + snapshots +
subscription instances + blocklist; keeps users/devices/config/tariffs/plans),
--config, --users, --all. Shifts/cash/payments live as event types inside the
hash-chained ledger_events, so --financial truncates the whole signed ledger
back to empty (re-seed starts a new chain under the SAME EVENT_SIGNING_KEY —
keys untouched).

Two safety gates: RESET_ALLOWED=1 env (a real booth never sets it) + typed
DB-filename confirmation (--yes skips for CI). Single transaction + VACUUM.

Verified on throwaway dev-DB copies: both gates refuse correctly; each flag
wipes/keeps the right tables; the real dev DB is never touched.

julian 84f00db48b feat(backup): admin-tunable retention + BACKUP_KEY as a Komodo secret
Build desktop / desktop (push) Successful in 4m17s
Build & push images / images (push) Failing after 39s
CI / check (push) Successful in 39s
Retention (keep-last / keep-daily-days) is operational policy the on-site admin
should tune, not a server env var requiring a redeploy -- same reasoning that moved
the target directory to the UI.

- Migration 0017: site_config.backup_keep_last + backup_keep_daily_days (nullable;
  null = code default 7 / 30 per field).
- BackupService reads retention fresh each run; status() exposes keepLast +
  keepDailyDays. DEFAULT_BACKUP_RETENTION is now a pure code default (env reads gone).
- PUT /api/backup/config accepts keepLast / keepDailyDays (non-negative int, or null
  to reset to default; 400 on negative).
- UI: two retention fields on the Backup config card; one Save covers target +
  retention. i18n sq + en.

BACKUP_KEY wired into Komodo:
- komodo/resources.toml: BACKUP_KEY=[[park_buzi_backup_key]] (per-booth secret,
  alongside JWT / signing keys).
- komodo/.env.komodo.example: documents it as the ONLY backup env var -- escrow it
  offsite alongside EVENT_SIGNING_KEY (recovery needs both); target + retention are
  admin-chosen in the UI / DB, not env. Server .env.example trimmed to just BACKUP_KEY.

Also carries the small in-progress setup-intro i18n copy trim.

Tests: 218 server tests green, incl. retention persist / reset-to-default / reject-
negative and the updated status shape. Migration applies cleanly (needed a
statement-breakpoint between the two ALTERs). Wiki backup-recovery updated.

julian d5e41500a8 feat(backup): admin UI with admin-chosen target directory
Build desktop / desktop (push) Successful in 4m42s
Build & push images / images (push) Successful in 2m53s
CI / check (push) Successful in 39s
The backup destination is now chosen by the on-site admin in the UI (Setup ->
Backup), not a server env var. An env-pinned target defeats the purpose: the admin
can't point backups at a freshly-plugged USB or a NAS mount without editing .env
and restarting. The encryption key stays a server secret.

Target storage:
- New site_config.backup_target_dir (migration 0016, nullable; null = not
  configured). BackupService reads it fresh each run, so a UI change takes effect
  with no restart. Only BACKUP_KEY stays env -- a key must never live in the DB it
  backs up.

Routes:
- PUT /api/backup/config  -- set/clear the target (backup:update; upserts id=1).
- POST /api/backup/test   -- probe a candidate path server-side (exists / is a
  directory / writable) so the admin gets feedback before relying on it.
- status() now exposes targetDir + keyPresent, so the UI distinguishes
  'no target set' from 'BACKUP_KEY missing'.

UI (apps/web/src/BackupSettings.tsx):
- A Setup -> Backup tab (gated backup:read): an editable target-path field with a
  Test-target probe (localized ok/missing/not-a-dir/not-writable), Save, the status
  panel (config state, last-run size/pruned/error, a distinct amber missing-key
  warning), a Back up now button, and the restore-is-out-of-band note. Full i18n
  (sq + en); nav.backup.
- API client: fetchBackupStatus / setBackupTarget / testBackupTarget / runBackup.

Also includes a small in-progress copy trim to the setup-intro i18n strings.

Verified live with Playwright: typed a path -> Test reported writable -> Save
persisted it -> status reflected it and showed the key-missing warning. Whole
monorepo build/lint/test green. Wiki backup-recovery + open-question #5 updated.

julian 0c218179c4 feat(backup): encrypted on-site DB backup engine + local target
The SQLite DB is the signed append-only ledger, so a disk failure / stolen or
destroyed PC means total revenue-history loss (open-question #5). This is the first
slice of the backup-recovery design: the engine + a local/mounted target + a daily
timer + a manual route.

Engine (apps/server/src/backup.ts):
- Consistent online copy of the live WAL DB via better-sqlite3's native .backup()
  (not a raw file copy, which can capture a torn WAL) — the restored copy is a
  byte-identical, queryable DB.
- AES-256-GCM with a scrypt-derived key from BACKUP_KEY; self-describing header
  (magic|version|salt|iv|...|authTag) so a restore tool needs only the key + file.
  Zero new dependencies (Node crypto).
- The plaintext intermediate is kept in scratch (not the removable/network target)
  and wiped in a finally, success or fail.
- Retention: keep-last-N + one-per-day within N days.

Wiring:
- BackupService (env config, single in-flight guard, last-success/last-error).
- routes/backup.ts: GET /api/backup/status (backup:read), POST /api/backup/run
  (backup:create), 409 when unconfigured. No restore route — restore is an
  out-of-band runbook action on a fresh appliance, not a console call.
- New  permission resource in @parking/shared.
- server.ts: an unref'd daily timer, a no-op until BACKUP_TARGET_DIR + BACKUP_KEY
  are set, deliberately not run at startup (a just-power-cut booth shouldn't write
  to a possibly-unmounted disk).
- openRawDb() added to @parking/db/testing (open a file without migrating, for
  restore-verification tests).

BACKUP_KEY is deliberately SEPARATE from EVENT_SIGNING_KEY (independent rotation;
backups travel, the signing key shouldn't). SMB/NFS work as mount paths; SFTP +
admin UI + restore runbook are deferred slices. Tests: round-trip byte-identical,
GCM tamper/wrong-key fail, short-key rejected, scratch cleaned, route auth/RBAC +
409. build/lint/test green (212 server tests). Wiki + open-question #5 updated.

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.

julian f706726eeb feat(prefs): per-user UI font scale (A−/A+), saved to the profile
A header A−/value/A+ control scales the whole UI, persisted per user and
restored on login from any booth — cloning the theme-pref pattern end to end.

- DB: users.font_scale (migration 0014; percent, 100 = base, NOT NULL default).
- Server: PUT /api/auth/font-scale (auth-guarded; clamps to 80–160, snaps to a
  10-step); fontScale flows through sessionView → login + /me.
- Client: setFontScalePref + applyFontScale; applied in App alongside theme;
  FontScaleToggle in the header; i18n sq+en.

Scaling uses CSS `zoom` on the root, NOT root font-size: the app's type is pinned
in px (text-[12px] etc., ~230 spots), which a font-size change would not scale —
so the dense Active-sessions / Live-feed logs stayed tiny. `zoom` scales
everything uniformly (text, spacing, icons) like the browser's Ctrl+/−, which is
the readability win for operators who need larger text.

Tests: 4 font-scale auth-route cases (persist + /me, clamp/snap, 400, default-100).
Full workspace build/lint/test green.

julian 4418594af0 refactor(setup): unify controller I/O — event-driven relays[] + generic inputs[]
Build desktop / desktop (push) Successful in 4m16s
Build & push images / images (push) Successful in 2m43s
CI / check (push) Successful in 38s
The controller new/edit modal hardcoded both its outputs and its inputs, so an

(e.g. a second radar at the exit). This unifies both into symmetric, first-class
lists. Behaviour for existing booths is unchanged (back-compat, no DB migration).

Outputs — one event→action relays[] list:
- A relay is "when EVENT X happens, do its action": entry/exit/both pulse a
  barrier; a new `radarAlert` event drives a non-barrier alert lamp (blink while
  its trigger input is active, SOLID once the camera confirms a car).
- Dropped the separate config.buttonLight block — the lamp is just a relays[] row
  with direction:"radarAlert" (triggerInput + blink cadence). `alertRelaysOf()`
  replaces `buttonLightOf()`; ButtonLightController keeps its proven 3-state
  machine (serialized UDP, fail-OFF, hot-reload), now keyed per controllerId:relay
  so several alert lamps on one controller run independently. Every barrier
  resolver skips radarAlert rows (no auto-open; barrier-not-a-door intact).

Inputs — one first-class config.inputs[] list (the twin of relays[]):
- Each row is { input, role, relay?, kind?, activeLow?, cooldownSec? } with a
  "+ Add input" button. role ∈ button | presence | alertTrigger; button/presence
  name the relay they serve. An exit radar is just another presence row.
- Keystone `inputsOf(row)`: returns config.inputs[] or SYNTHESIZES it from the
  legacy relays[].button/presenceInput/... fields, so relayForButton /
  relayForPresence resolve identically from either shape — zero-downtime, no
  migration. entry-flow.ts is unchanged (resolves through the same functions).
- Fixed a latent bug this exposed: the alert lamp's camera lock was hardcoded to
  the ENTRY camera. Added relays[].lockLane ("entry"|"exit", default entry); the
  lamp now locks on its own lane's camera, so an exit radar's lamp tracks the exit
  camera. button-light tracks both #entryBusy/#exitBusy.
- Driver: extracted activeLowFrom(config) — merges inputs[] activeLow, legacy
  relays[].presenceActiveLow, and the inputActiveLow escape hatch.

UI: the relay dropdown gained a "Radar alert" option (reveals trigger/lock/blink
inputs); InputEditor is rewritten to a generic list (role select folds loop/radar);
i18n sq+en kept at type-parity.

Tests: new device-resolve.test.ts (inputs[] resolution + legacy fallback identical
+ exit-radar resolves to the exit relay); button-light gains a two-independent-
alert-relays case and an exit-lamp lockLane case; access-dingtian gains
activeLowFrom cases. Full workspace build/lint/test green (i18n parity included).

Wiki + memory updated (button-light-indicator, entry-double-press, dingtian-relay).

julian 916c147b4d fix(camera): drop debug console.log(c) leaking the camera password to logs
Build desktop / desktop (push) Successful in 4m39s
Build & push images / images (push) Successful in 2m49s
CI / check (push) Successful in 41s
The Hikvision driver's create() had a leftover `console.log(c)` that dumped the
ENTIRE camera config — including the plaintext `password` — to stdout every time
the adapter was built, on every request that resolves a camera. That puts a device
credential in the logs (which get shipped/cached/read — the booth operator is the
adversary). Removed. Swept the rest of the shipped source: no other console.* leaks.

julian dd0f6e483a fix(reader): real ICMP liveness — QR reader status was a hardcoded "ready"
Two genuinely-offline QR readers showed GREEN: the adapter's healthCheck was
hardcoded to { ready, "stub" } and never probed. These are PUSH devices (scan →
GET our backend, resolve by serial) with NO TCP port, so a connect probe has
nothing to hit — the stub "solved" that by lying. False-healthy is the worst
failure for a status bar.

- Optional reader IP field (monitor-ONLY; scans still resolve by serial,
  operation unchanged).
- Unprivileged ICMP ping (drivers/icmp.ts): shells /bin/ping -c1, exit-0 = reply.
  No native dep, no CAP_NET_RAW. docker-compose.prod.yml sets
  net.ipv4.ping_group_range so it works for the non-root container user.
- healthCheck: replies → ready, no reply → offline, NO IP → degraded
  ("set IP to monitor") — never a false green.

Verified on hardware: readers (10.0.10.7/.8) answer ICMP on the device VLAN;
UI Test connection → "● ready — ping 10.0.10.7". Tests: reader.test.ts (4).

julian f0fd15bb88 fix(camera): selectable snapshot stream + retry transient 503 Device Busy
A Hikvision DS-2CD1047G3H-LIU returned HTTP 503 (statusCode 2 / deviceBusy)
on EVERY main-stream snapshot — its main encoder is persistently saturated.
Probed on hardware: channels/101/picture → 503 on 5 consecutive tries, while
channels/102/picture (sub stream) → 200 clean JPEG every time. A retry loop
can't fix a persistent busy; the real fix is stream selection.

- Add a `stream` config field to the Hikvision driver (1=main, default for
  back-compat; 2=sub). ISAPI channel id is <channel><stream> (101 main, 102 sub).
  Verified live: setting the G3H to Sub flips its status degraded→ready (14.7KB
  JPEG in ~87ms).
- captureSnapshot also retries the TRANSIENT case (503/500, linear backoff
  250/500/750ms ×4) then fails naming it "(device busy)"; does NOT retry 401/404
  (config errors won't self-heal). Complements captureSnapshotShared (concurrent
  de-dup). healthCheck still reports a live 503 as degraded (surfaces a saturated
  main stream rather than hiding it).

Tests: camera.test.ts (10) — retry behaviour + main/sub path selection.

julian 7366ad19cb feat(printer): USB transport behind the ESC/POS render layer
The ESC/POS printer drivers were TCP-only — every path went through
sendRaw/probe to a raw socket on port 9100. Add a USB transport behind
the existing render layer without touching a single render*() function.

- printer-escpos.ts: sendRawUsb/probeUsb write the same ESC/POS bytes to a
  kernel usblp char device (/dev/usb/lp0) via a plain fs write — no
  libusb/CUPS/native dep (keeps MIT-only + minimal-deps appliance). A
  discriminated Transport + transportFromConfig/sendTo/probeTo dispatch the
  wire; anything not transport:"usb" is TCP, so existing host-only configs
  need no migration. Shared transportField/devicePathField config fields.
- cashino + rongta resolve a Transport once; both are reachability-only over
  USB, and the Rongta's HTTP status page degrades to the open-the-node probe
  over USB (no guessed paper/cover — the standing honesty rule). host/port
  made not-required so a USB printer needs neither.
- Tests: printer-escpos.test.ts (USB writes the exact rendered bytes; probe
  present/absent; transportFromConfig TCP back-compat) + printer-cashino.test.ts
  (USB-configured driver prints to the node, ready/offline).

USB itself is unverified on hardware (the on-site printers are networked);
the appliance-side usblp + udev provisioning is tracked as open-questions #14.

julian 420542ce10 fix(setup): add Dingtian relay-password field + secure secret re-merge on test
The relay control password (relay_pw) was read by the driver but had NO form field,
so Test connection sent it as 0 → the device ignored the probe → a controller showed
"offline" even though it pinged. Add a "Relay control password" config field (secret;
blank keeps the stored value).

Because relayPassword is redacted from the client, the edit form can't resend it — so
the test endpoint now re-merges the stored secret by device id (mirroring save). It is
re-merged ONLY when the submitted config addresses the SAME device: matching driverId
and every connection-identity field it sets (host/port/binaryPort/httpPort/serial). A
redirected host/port or mismatched driver yields NO secret, so a probe can't exfiltrate
the password to an attacker host (the booth operator is the threat-model adversary).
testDevice() now passes the device id; setup-secrets.test.ts covers the identity guard.

julian 2915d141aa feat(devices): radar presence input + button-light output on the controller
Model the entry button (I1) and a Hikvision radar (I2) as named children of the
access controller, and drive the button's 12V lamp on a spare relay.

- Radar = the existing relays[].presenceInput one-car-one-ticket gate, now labelled
  presenceKind: loop|radar. A radar may idle opposite the button, so add a per-input
  active-level override: relays[].presenceActiveLow -> driver inputActiveLow set,
  inverting just that terminal (pure helper inputActive()). The Dingtian has one
  board-wide resting level otherwise.
- AuxOutputDevice.setAux(channel,on) capability on the device interface (Dingtian
  latch) so business logic drives a NON-barrier lamp through the interface. Barriers
  still only pulseOpen — barrier-not-a-door preserved.
- ButtonLightController: subscribes to the radar input edge + the camera lane status
  and drives a 3-state lamp — radar+car=solid, radar-only=blink (~1Hz), else off.
  Fails OFF on host loss/error; de-duped. A radar detection never opens a barrier on
  its own (advisory; threat model).
- SetupWizard: presence kind + active-low + a button-light relay picker; sq+en i18n.

Tests: button-light.test.ts (truth table + blink + fail-OFF + de-dupe),
access-dingtian.test.ts (active-level inversion). Workspace build+lint+test green

CI / check (push) Successful in 35s
Build & push images / images (push) Failing after 17s
Containerize the two non-desktop apps for the booth appliance. The desktop app stays
on its own tag-only release.yml.

- apps/server/Dockerfile: multi-stage node:22-alpine. `pnpm deploy --legacy --prod`
  (NOT prune — the monorepo native better-sqlite3 won't resolve under a root prune)
  yields a self-contained bundle; build stage adds node-gyp toolchain, runtime adds
  libstdc++; non-root, healthcheck. Migrates the mounted DB on boot via a drizzle-kit-
  free runtime migrator (packages/db/scripts/migrate-runtime.mjs) — drizzle-kit is a
  devDep, pruned from prod.
- apps/server/src/static-spa.ts: Fastify serves the built React SPA (one container
  serves API + UI). GET-only fallback to index.html, excludes /api + /health so it never
  shadows the backend; a no-op in dev (no dist). Registered last in server.ts.
- apps/vision/Dockerfile: uv base, --extra alpr, model weights PRE-WARMED into the image
  as the runtime user so fast_alpr boots offline (0 downloads at runtime). Engine env-
  selected (VISION_RECOGNIZER stub|fast_alpr).
- Branch-aware: docker-compose.yml (base) + .dev.yml (build local, stub, ports) +
  .prod.yml (pull pinned, fast_alpr, vision internal, restart always); REGISTRY/TAG from
  env so a branch deploy pulls that branch's image.
- .gitea/workflows/build-images.yml: on push to dev/main, run the full turbo build+lint+
  test gate, then buildx push both images to git.infra.msai.al/mca/parking_solution with
  branch + branch-<sha> tags (registry cache; optional Komodo webhook behind KOMODO_ENABLED).
- .dockerignore excludes **/parking.sqlite* so the signed ledger is NEVER baked.

Verified locally (Docker 29): server image migrates + serves API+SPA (/health 200, /

julian 8a437d0c4b feat(booth): cancel wrongly-printed ticket (signed void) + refused-vs-anomaly display; fix CI uv
CI / check (push) Failing after 56s
Cancel a misprinted/test/wrong-vehicle ticket via a SIGNED `void` event — the
vehicle_entry is never edited/deleted (append-only). VoidFlow appends void{
voidedEntryRef, voidReason, operator, reasonCode:"void.ticketCancelled" }; route
POST /api/tickets/void gated event:void + open shift; reason REQUIRED. Refuses a
subscription / already-exited / already-voided / paid ticket (refund out of scope).
The void folds the session CLOSED everywhere it's counted — occupancy (count +
reserved spots), pay-station (lookup/activeSessions), exit-flow (#sessionFor), and
reports (excluded from entries) — so a voided car stops occupying a spot, can't be
paid/exited, and doesn't inflate "cars entered". No barrier action. Booth UI: a
"Cancel ticket" action in the pay/exit lookup modal (transient + unpaid + open;
gated on event:void) with a preset-or-free reason prompt.

Reclassify the Live feed: refused-action events (exitRefused/entryRefused/
permitRefused — e.g. a double card-scan, at-capacity subscriber, exit on a closed
session) are benign warnings, not red anomalies. event-detail.tsx now shows them as
amber REFUZUAR/REFUSED, reserving red ANOMALI for genuine red-flags. Display-only —
no ledger change, so historical events reclassify too.

CI: install uv + sync vision deps before the Turbo run. @parking/vision's lint/
typecheck/test shell to `uv run …`, but CI set up only Node+pnpm, so `uv run ruff`
failed ("uv not found") and broke the whole Turbo run. The Python checks pass once
uv provisions the toolchain.

julian 65328b8c11 feat(anpr): subscriber-entry bridge + admin disable toggle
CI / check (push) Failing after 15s
Wire the lane camera's vehicle event into the gated subscription flow: on a
vehicle/active push from an opt-in (config.anpr) camera, AnprBridge pulls a fresh
snapshot, runs ANPR, applies a stricter entry confidence floor, debounces, and —
matching the plate to a subscription BEFORE emitting — emits a kind:"plate" read.
The existing ReadDispatcher -> SubscriptionFlow then signs the entry/exit and opens
the barrier. A plate is never the sole authority: it routes through the same gate
(active/window/blocklist/car-count) as any credential. Fail-soft, fire-and-forget,
subscriber-only by construction. Field-verified end to end (plate AA504LX opened the
entry barrier and appended a signed vehicle_entry).

Add an admin master switch (site_config.anpr_entry_enabled, default ON) in Site
Settings that disables ONLY the barrier-driving bridge; advisory snapshot-ANPR and
lane busy/free are unaffected. Read live per event, so toggling takes effect with no
restart. Migration 0013 (additive ALTER ADD COLUMN, default 1).

julian b7300ec080 fix(hik-alarm): listen on all methods + skippable source-IP guard (WSL)
Diagnosed why no camera push ever landed: (1) the route only registered
POST/GET, so a probe with another method got a generic 404 the camera
reads as "service available" while our handler never ran; (2) more
fundamentally, WSL mirrored mode REWRITES the inbound source IP to the
host's own address (10.0.10.203), so the camera's real IP (10.0.10.12)
never survives and the source-IP guard rejected every push as a mismatch.

- Register the event route on POST/GET/PUT/PATCH/DELETE/OPTIONS (HEAD comes
  with GET) so ANYTHING hitting the path reaches the handler and is recorded.
- Log + store the HTTP method of each hit; log every hit on arrival, before
  any guard, so even a rejected probe is visible immediately.
- Add per-device skipSourceIpCheck (a Setup checkbox) to bypass the
  source-IP guard where the network rewrites the source (WSL). Digest auth +
  the signed ledger remain the real guards.

Tests: hik-alarm 10 (skip-IP accept + method capture). server green;
web build green (new checkbox renderer + this field).

julian 6133923094 feat(camera): Hikvision Alarm Server event-push ingress (discovery-first)
Newer Hik firmware can PUSH events to us: Event -> Smart/VCA with
"Detection Target: Human/Vehicle" + Notify Surveillance Center + Alarm
Settings -> Alarm Server makes the camera HTTP-POST an
EventNotificationAlert on each detection.

- New POST /api/devices/hikvision/:deviceId/event (routes/hikvision-alarm.ts):
  same machine-push pattern as the Dingtian Input Link — source-IP guarded
  + optional HTTP Digest, not behind the SPA cookie/CSRF.
- Discovery-first / permissive: a wildcard content-type parser accepts ANY
  body as raw bytes (event XML, multipart+JPEG, or JSON — Hik varies by
  firmware), records it verbatim as a kind:"alarm" device_event, and
  best-effort extracts eventType/target/plate/dateTime/channelID for the
  summary + a loud log line. The point is to SEE exactly what a camera
  sends before wiring it further.
- hikvision driver gains alarmPushEnabled + pushUser/pushPassword config and
  pushesToBackend:true (setup offers the backend push IP).
- NOT yet a barrier trigger / DeviceReadEvent — records only. A plate read
  is advisory, never the sole reason a barrier opens; the read-bus/ANPR
  wiring is a deliberate next step once the real payload is known.

julian 7680d9a0ed feat(recycle-bin): soft delete + restore for master data
Accidental admin deletes of users/roles/subscriptions/plans/tariffs were
hard and unrecoverable. Now they soft-delete into a recycle bin.

Schema (migration 0012): nullable deleted_at + deleted_by on users, roles,
subscriptions, subscription_plans, tariffs. Additive ADD COLUMN; verified
against a copy of the live DB.

Backend: each resource's DELETE route STAMPS instead of removing; every
catalog list filters deleted_at IS NULL. New recycle-bin module + routes
(GET /api/recycle-bin, POST .../restore, DELETE .../:id purge) gated on a
new recyclebin:read/update/delete permission. A 6-hourly + startup sweep
auto-purges items older than RECYCLE_BIN_RETENTION_DAYS (default 30; 0 =
forever).

Invariants: soft-deleted users can't log in (login rejects deleted_at;
no-lockout counts live admins only); a soft-deleted subscription doesn't
open the barrier; plans are versioned so a delete stamps all versions of
the plan_id (bin shows one item); username/role-name UNIQUE spans deleted
rows so reuse returns a clear 409 pointing at the bin; restore doesn't
auto-cascade a dangling role (guard resolves missing role to empty perms).
The signed append-only ledger is OUT of scope (no delete path).

purge confirm; api client + i18n (sq + en parity).

  occurrence id at width 2 so it fits the 80mm head (width 3 overflows ~576 dots and
  the firmware silently aborts the barcode). Plus the QR-and-Code128 dual encoding and
  the Albanian stamp() format.
