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.

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.

Promotion of the entry presence-gate bypass (+ signed relay test): merge is on
stage, CI built :stage-6505a4a (pull verified). Bump the park-buzi Stack pin to
the new immutable sha. Deploy is the manual Komodo step: refresh ResourceSync →
Execute → Deploy; watch for [migrate] done (carries 0020 — two site_config
bypass columns, additive, applied at boot against the /data volume).
Claude-Session: https://claude.ai/code/session_01Xcm6ikLgGoCxxHrxtjkk5V
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).

Two unrelated leftover wiki edits from earlier sessions:
- NEW concepts/vision-service-hardening.md: the prioritised to-do list from the
2026-07-02 code + security reviews of apps/vision/ (DoS gaps, unauthenticated/
operator-writable model weights, 0.0.0.0 default bind). Cross-linked from
opencv-anpr-service.md ("consult before touching this service").
- container-deployment.md: note that a boot-time migration can be a DATA SEED
(e.g. an RBAC permission granted to the operator role via INSERT OR IGNORE),
and that a built-in-role grant does not auto-apply to a custom role.
Claude-Session: https://claude.ai/code/session_01Xcm6ikLgGoCxxHrxtjkk5V
No secure element is on-site: event signing runs on the software HMAC
(EVENT_SIGNING_KEY, an env var on the host disk), so the ledger is
tamper-EVIDENT but forgeable by anyone who owns the host. Several pages
overstated it as present-tense "ATECC608-signed / unforgeable"; correct them.
- NEW concepts/hardware-signer-options.md: four options for a non-extractable
signing key (USB HSM / YubiKey / reuse the TPM / plain-dongle trap) + the
recommendation (TPM interim → USB-HSM target; ATECC608 stays for the embedded
ESP32, wrong part for a PC host).
- entities/atecc608.md: UPCOMING-not-present status banner + PC-vs-embedded.
- disk-os-hardening.md: fix the live-USB row (BIOS boot-order password is
load-bearing, not Secure Boot — a signed live USB runs); add a physical-tamper
chain (Dell 7070 CMOS-reset → live-USB → PCR-7 same-signer unseal) + accepted
risks (that unseal, unsigned-initramfs evil-maid, operator-USB read TODO).
- open-questions #6 reframed; standing-decisions / overview / threat-model /
index de-overstated; log query entry.
Claude-Session: https://claude.ai/code/session_01Xcm6ikLgGoCxxHrxtjkk5V
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.

Promote to staging (park-buzi): snapshot content-type fix, Active Sessions/modal
rework, DB reset CLI, drawer redesign (operator records / admin reviews), card
tender disabled (no POS), operator-issued entry + exit plate-swap reconciliation.
Migrations 0018 (drawer permissions) + 0019 (session:create) run at container
boot. TAG in komodo/resources.toml still points at the OLD image — re-pin to the
new stage-<sha> CI produces from this merge before deploying.

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."

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.

No card processor / POS terminal on any site yet. Offering "Card" would let an
operator record a card payment that never cleared a terminal, corrupting the
till reconciliation — a fraud/error surface on an operator-adversary system.
Add apps/web/src/lib/features.ts → CARD_PAYMENTS_ENABLED=false, gating both
tender pickers (BoothPayModal, SubscriptionManager). With card off there's
nothing to choose, so the tender row is suppressed and payment defaults to
cash. UI-only gate: the Tender type, payment events, shift accounting, and
reports still understand `card`, so historical card events and a future
re-enable stay coherent.
Verified via Playwright: an unpaid-ticket modal shows Total + "Pay + open
barrier" with no tender/cash/card row.
Wiki: new concepts/card-payments.md records the current cash-only state, the
PCI-scope-out-of-app constraint, the future-POS device requirements, and the
re-enable path (flip the flag once a bank-certified P2PE terminal is
provisioned). Linked from index, parking-session, open-questions #3.

- entry-exit-points.md: the snapshot content-type bug + serve-side cleanType
fix (Hikvision image/jpeg; charset="UTF-8" broke every legacy render).
- booth-exit-flow.md: the Active-Sessions/modal rework — inline barrier button
removed -> modal; closed-within-grace view; live grace countdown; actual paid
amount; read-only snapshot review in the closed-session view.
- local-dev-workflow.md: the gated `pnpm db:reset` training tool + flag table +
the booth (docker exec, no pnpm) note.
- appliance-provisioning.md: new §7d — reset on the booth via docker exec into
the server container (script ships in the deploy bundle; DATABASE_URL=
/data/parking.sqlite), ledger-truncation warning + the two safety gates.
- index.md catalog line; log.md entries.

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.

Move the audited barrier re-open out of the inline Active-Sessions row button
and into the modal, and turn the modal's dead-ends into useful views.
- Remove the inline per-row "Open barrier" button. Clicking a row opens the
modal, which carries the action.
- Modal recognizes a closed-within-grace transient (found && !open &&
withinGrace) and shows the session view + Open barrier instead of dead-ending
on "already closed" — the exact case (paid, barrier unconfirmed) that needs a
re-pulse. Server reopenBarrier guard unchanged.
- Active-Sessions rows show a live grace-remaining countdown badge
(exited - M:SS, 1s tick off graceExpiresAt) via new formatCountdown helper.
- Settled sessions show the ACTUAL sum paid (new SessionLookup.paidMinor,
summed across payment events) instead of a flat "PAID" badge.
- A fully-closed (grace-expired) session's modal is no longer a dead-end: it
shows a read-only review view (figures + paid amount + entry/exit snapshot
strip) for dispute/audit review, with no pay/exit/open controls.
i18n sq+en parity kept; web build/lint/test green.

Cameras (Hikvision) return `Content-Type: image/jpeg; charset="UTF-8"` — a
charset param on a binary body is malformed, and browsers refuse to decode an
<img> declared that way. Old capture code persisted that raw header into
snapshots.content_type (100/101 dev-DB rows); GET /api/snapshots/:id re-emitted
it verbatim, so every legacy snapshot rendered blank in the booth modal.
Capture was already hardened (encodeForStorage re-encodes to a clean
image/jpeg, fail-soft via cleanType), but the serve route trusted the stored
value. Export cleanType and apply it when setting the response header, so a
bare image/jpeg is sent regardless of what was stored — un-breaks all legacy
rows with no data migration. A stored value from an untrusted device is itself
input; normalize on capture AND on serve. Adds cleanType unit tests.
Verified: a previously-unrenderable 2560x1440 row now decodes in-browser.

Two lessons from the first park-buzi staging deploy, both in backup-recovery.md:
- A new server env var (BACKUP_KEY) must be added to docker-compose.yml's
server.environment: allowlist, not just the Komodo secret/Stack env — otherwise
the container never receives it (inspect shows it absent, not empty).
- The backup target must be a host path bind-mounted into the container; a desktop-
automounted USB (/run/media/...) is invisible inside the container, so Test target
reports 'does not exist'. Destinations are admin-provisioned (fstab + compose bind-
mount), not operator-pluggable — partly a threat-model feature. Acknowledged as a
flexibility limitation; USB-automount-to-container flow deferred.
Claude-Session: https://claude.ai/code/session_01Xcm6ikLgGoCxxHrxtjkk5V
The server's compose environment: block is an allowlist — it only forwards the vars
it names. BACKUP_KEY was never added when the backup feature landed, so even though
Komodo wrote BACKUP_KEY into the Stack .env, compose dropped it and the container
came up without it (docker inspect showed JWT/SIGN present, BACKUP_KEY absent — not
empty, absent). The Backup screen correctly reported 'BACKUP_KEY missing'.
Add BACKUP_KEY: ${BACKUP_KEY:-} next to EVENT_SIGNING_KEY (optional, empty default —
backups stay off until it's set). The prod overlay only merges VISION_URL, so the
base addition flows through to prod.

The first :stage image is built and in the registry (stage-39c778f). Pin it in the

A push only builds if it touches a path in the filter. The first stage commit was

(and a komodo-only push to stage) also build+check — a deploy-config change gets the
same sanity pass before it reaches a booth. This commit itself touches the workflow
file (already filtered), so it triggers the build that produces the first :stage image.

Model the staging-vs-production split that fleet-deployment-komodo flagged as open.
Three tiers: dev (working, no booth) -> stage (staging booth park-buzi, real-world
test) -> main (production, manual + pinned).
- build-images.yml: trigger on [dev, stage, main]. The tag computation is already
branch-derived, so :stage / :stage-<sha> build with no other change.
- komodo/resources.toml: park-buzi now branch=stage + TAG=stage-<sha> (pinned;
no webhook even on staging). BACKUP_KEY already wired as a per-booth secret.
- komodo/README.md: a Promotion (dev->stage->main) section; per-booth secret list
now includes backup_key; hard-rule #1 generalised to pinned <branch>-<sha>.
- wiki: fleet-deployment-komodo open-item resolved + a Promotion-tiers table;
deploy-trigger choice generalised; container-deployment tag list gains :stage.
Promotion is a merge: when dev is ready, merge dev->stage, CI builds the image,
bump TAG=stage-<sha> in resources.toml, deploy from Core. stage is branched from
dev HEAD so the first real-world test carries the full current app. Per-booth
secrets must pre-exist in Core; migrations run at boot so a promotion auto-migrates
the staging ledger (where a bad migration is caught before production).

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.
Claude-Session: https://claude.ai/code/session_01Xcm6ikLgGoCxxHrxtjkk5V
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.

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.

New concept page backup-recovery.md resolving the design half of open-question #5.
Driving scenario: a stolen/destroyed PC whose LUKS+TPM disk is unrecoverable by
design — recovery stands up a NEW PC, restores a backup, and keeps signing the
SAME chain.
Settled: admin-driven encrypted full-DB backup (SQLite online-backup/VACUUM INTO,
snapshots included) to local/USB, SMB/NFS, or SFTP targets; manual button + an
in-process daily timer; keep-last-N + dailies retention; restore is admin-only /
out-of-band (operator-adversary surface). A restored copy must still verifyChain.
Key custody (the load-bearing decision, bears on #6): three independent keys —
EVENT_SIGNING_KEY kept an extractable, escrowed software key DECOUPLED from the
TPM so the ledger survives total hardware loss (the conscious trade: a TPM-sealed
signing key would be unforgeable but permanently unverifiable after the machine
dies); a NEW dedicated park_buzi_backup_key in Komodo for backup encryption,
separate from the signing key; the LUKS/TPM disk key, appliance-only and
deliberately non-recoverable. Keys are never inside the backup they unlock.
Updated open-questions #5 (design SETTLED) + #10 note; disk-os-hardening deploy
runbook (why the signing key is not sealed + park_buzi_backup_key); index catalog
+ concept count. Design only — not yet built.

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).

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.

Camera snapshots were stored RAW — the camera's full-res JPEG straight into
the BLOB, no resize/recompress. Measured on the dev DB: 300 snapshots = 81.7 MB
= ~72% of the 114 MB SQLite file (the big ones 2688×1520 / ~600 KB, Hikvision
main stream). They dominated the appliance's single backed-up DB file.
Re-encode on capture (snapshot.ts):
- Downscale each frame to SNAPSHOT_MAX_EDGE (1280px long edge) + recompress at
SNAPSHOT_JPEG_QUALITY (80) via sharp (libvips, Apache-2.0) before storage —
~6-10× smaller (verified 2688×1520 → 1280×724, ~8×), plate still readable,
clean image/jpeg (drops the camera's charset cruft). STORAGE-ONLY: recognition
keeps the ORIGINAL full-res bytes (downscaling hurts OCR). Fail-soft — a
re-encode error stores the original, never drops the snapshot or blocks the
(already-open) path. sharp lives in apps/server (owns the capture path), where
bcrypt already establishes the native-dep pattern.
Disk-pressure retention (snapshot-retention.ts) — a SAFETY VALVE, not the daily
mechanism (the re-encode does that). Daily check reads the DB filesystem used%
(statfs on db.$client.name); no-op unless ≥ SNAPSHOT_DISK_HIGH_PCT (70). Over the
mark: delete the OLDEST until an estimated SNAPSHOT_DISK_FREE_TARGET_PCT (10%) of
disk is freed — never below SNAPSHOT_MIN_KEEP (500) — then VACUUM once to return
space to the OS. A DELETE only frees SQLite pages (disk doesn't drop until VACUUM),
so the loop is driven by estimated freed bytes (SUM(length(bytes))), not a live
disk re-read; the prune owns the DB-locking VACUUM, run daily off-peak. diskUsage
is injectable for tests. None of this touches the signed ledger — snapshots are
unsigned/advisory, referenced only by id.
Tests: encodeForStorage (downscale / clean-type / no-enlarge / fail-soft) +
pruneSnapshots (no-op below mark / delete-oldest-to-target + VACUUM / MIN_KEEP
floor / skip-VACUUM-when-empty). All four snapshot env knobs documented in the
komodo env reference. Full workspace build/lint/test green; the prune smoke-verified
on a scratch DB copy (file shrank after VACUUM).
Existing ~81.7 MB of raw snapshots are unchanged (a one-off re-encode backfill is
a separate optional follow-up). Updated entry-exit-points + technology-stack wiki.

A round of operator-facing fixes on the booth screen, shift views, and the
font-scale control. (Follows the font-scale feature in f706726, which used CSS
`zoom` — reverted here for the rem approach below.)
Font scaling (the A−/A+ control now actually works without breaking layout):
- The control scaled via CSS `zoom`, which also scaled viewport-locked containers
(h-screen frame, max-h-[90vh] modals) so at 130% modal headers/footers were
pushed off-screen. Reworked to scale TEXT only: converted every `text-[Npx]`
font utility to rem across the web app (~230 sites in 25 files + the
.label/.hint/.btn component classes + body in index.css; 16px root, so 100% is
visually identical), and applyFontScale now sets the ROOT font-size. vh/h-screen
layout stays put, so chrome never clips; tall content scrolls its own container.
Verified at 130%: text 12px→15.6px while the frame stayed viewport-height.
Live feed (event rows):
- Plate, badges and reason now flow inline after the identity and wrap only when
the row runs out of width — no more forced second line when there's empty space.
- Dropped the redundant TARGË via-badge (the plate chip already conveys it).
- Removed the Direction filter group (Hyrje/Dalje) — it duplicated the entry/exit
options already in the Type filter.
Active sessions:
- Rebuilt as a real table (Ticket/subscriber · Plate · Entry · Elapsed) so columns
align and long values (subscriber names, ticket ids) no longer truncate.
- Dropped the status column (an unpaid transient is normal; a subscriber shows ★ +
name; overstay keeps a row tint). Removed the now-redundant status filter; only
the Transient/Subscriber filter remains. Plate is now searchable (uses s.plate).
Shift report (close-shift modal + Shift History + printed Z-report slip):
- Removed the confusing `shitje` (subscription-sales) sub-line — Abonime is the
total; only the out-of-window part is broken out. subscriptionSalesMinor stays in
the signed payload (audit data), just not displayed/printed.
- Show the inherited opening cash ("Arka fillestare") above the expected drawer, so
opening + cash-taken = expected reads clearly. Money values no longer line-wrap.
Subscription edit modal:
- Fixed the 2-col grid alignment: a lone "only one version" cell was shifting every
following row by one column — it now emits a full label+value pair.
Removed orphaned i18n keys (fStatus*, fDir*, srcSubSales) from sq+en (parity kept).

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.

Two booth feed fixes:
- Plate not showing until refresh. Plate recognition is async/advisory
(snapshot.ts recognizePlate → a kind:"read" device_event keyed by the session
identity), so it lands AFTER the entry/exit event already shipped over the WS
without a plate; a refresh re-fetched via the bulk enrich path and showed it.
Added a `plate-recognized` bus event (device-events.ts) emitted when the read
is written; ws.ts forwards it; the client patchPlate(identity, plate)
(live-store) backfills the already-rendered feed row in place and invalidates
the Query-owned active-sessions list. No refresh.
- Plate search didn't filter. Both the live-feed (BoothScreen) and active-sessions
(ActiveSessions) search haystacks matched the wrong field — the displayed plate
is the ENRICHED top-level e.plate/s.plate (set by enrichEvent), not payload.plate
(the plate is unsigned, never in the signed payload). Switched the haystacks to
the displayed field.

The on-screen Hyrje/Dalje barrier lights were 2-state (green=free / red=busy)
off the camera lane-status only — they couldn't show the radar-only "detected,
not yet confirmed" state that makes the physical button lamp (relay 3) blink.
Now they mirror the lamp's 3-state rule per lane:
radar present + camera not busy → BLINK green↔red (~1 Hz)
camera busy → SOLID red
otherwise → SOLID green
End-to-end:
- LanePresence (lane-presence.ts): subscribes to deviceEvents.onInput, resolves
each presence edge to its lane via the new direction-agnostic presenceLaneOf()
(device-resolve.ts) — entry AND exit, unlike the entry-gated relayForPresence
the one-car-one-ticket gate uses — and emits a lane-presence {entry,exit} bus
event on change. Wired in server.ts (start + onClose).
- WS forwards it (hello snapshot + push) into live-store.radar.
- BarrierLight (BoothScreen.tsx) is now 3-state; blinks via the .lane-blink
keyframe (index.css), which holds solid-red under prefers-reduced-motion.
Same input + same rule as the lamp, so the screen and the post never disagree.
A new test (lane-presence.test.ts) caught a real bug: the first cut reused
relayForPresence, so the EXIT lane never resolved (it's entry-gated) and never
blinked — presenceLaneOf fixes it. Covers entry/exit independence, de-dupe
across several radars on one lane, and ignoring non-presence inputs.
Full workspace build/lint/test green (185 server tests). Updated the
button-light-indicator wiki page ("On-screen twin").
Claude-Session: https://claude.ai/code/session_01Xcm6ikLgGoCxxHrxtjkk5V
The controller new/edit modal hardcoded both its outputs and its inputs, so an
operator could neither add a generic event-driven relay nor a free-standing input
(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).

A shared entry/exit lane has both an entry and an exit camera on ONE lane: a
subscriber driving IN is admitted by the entry cam, but the exit cam sees the same
car leaving its frame and phantom-EXITs the occurrence just opened (its back plate).
Separate RECOGNITION from AUTO-OPEN per camera:
- config.anpr (unchanged) = run snapshots through the recognizer, record the plate
(evidence), BOTH directions — stays on.
- config.anprAutoTrigger (new, absent ⇒ on when anpr is on) = may THIS camera
auto-open the barrier. Set false on the shared-lane exit cam: it still recognises
plates but never auto-triggers. The bridge gates on it (anpr-entry.ts), before the
poll loop.
UI: a "Auto open/close on subscriber plate" checkbox under ANPR in the camera setup
(shown when anpr is on); persisted true/false so a park can explicitly disable it.
i18n sq+en (also corrected the now-stale anprHint "never opens a barrier" wording —
it does, via the bridge). +1 server test (anprAutoTrigger=false → no snapshot, no
read); 172 green. Documented the two toggle levels (site-wide + per-camera) in
lane-presence-and-anpr-entry.

A loop started by a far/early car would (a) give up before the REAL car settled at
the barrier, and (b) swallow the real car's pushes (the #polling guard dropped them).
So a confident-but-wrong far-car plate could win, or the intended car get debounced
out after the loop ended — wrong car acted on, right car blocked.
Fix: a push that JOINS a running loop now EXTENDS the deadline (lastPush +
ANPR_POLL_WINDOW_MS) instead of being dropped, capped at start + ANPR_POLL_MAX_MS
(30s) so a continuously-busy lane can't slide forever. Each tick still pulls a FRESH
frame, so the loop tracks whoever is at the barrier NOW, not the car that started it.
Per-camera sliding deadline in #pollDeadline (cleared with #polling in finally).
+1 test (push mid-poll keeps the loop alive past the initial deadline); 171 server
tests green. New knob ANPR_POLL_MAX_MS documented in the komodo env reference + the
two concurrency guards written up in lane-presence-and-anpr-entry.

The Stack example only listed the required set; expand it to the FULL reference so
an operator can see (and tweak) every env without digging through code. Grouped:
- IMAGE SELECTION (REGISTRY, TAG)
- REQUIRED (JWT_SECRET, EVENT_SIGNING_KEY, COOKIE_SECURE — no safe default)
- COMMONLY SET (VISION_ENABLED, WS_ALLOWED_ORIGINS)
- SET BY COMPOSE — don't put in the Stack (VISION_URL, DATABASE_URL, VISION_RECOGNIZER)
- OPTIONAL TUNABLES with code defaults: ports, logging/retention, device+printer poll
intervals, lane/capture TTLs, and the ANPR knobs incl. this session's new
ANPR_POLL_MS=1000 / ANPR_POLL_WINDOW_MS=8000 (raise the window for a slow barrier)
- VISION CONTAINER env (the Python service's own VISION_* vars)
All defaults pulled from the code (process.env.X ?? default). Documentation only.
apps/web/.env.production hardcoded VITE_API_BASE=http://127.0.0.1:3000 — a
desktop-only value that's WRONG for the booth, which serves the SPA same-origin
(Fastify dist/ via Caddy :80) and needs a RELATIVE /api base. An absolute origin
baked at build would point the browser at localhost. origin.ts treats empty as
relative (API_BASE=""), matching the deploy (the 77b2acb fix / container-deployment
"Web access").
The desktop (Tauri) build DOES need an absolute origin, but that app is a deferred
separate task (currently hardcoded localhost); it must set VITE_API_BASE for its own
build when resumed, not here. Comment updated to say so.
The poll-until-confident loop (prev commit) opened a race: during its ~8s window a
subscriber could scan their card/QR at the reader and exit immediately — but the ANPR
loop kept polling and would ALSO emit a confident read a moment later, exiting the
NEXT open occurrence (a phantom double-exit, worst for a fleet sub with several open).
Guard it with the subscriber's open-occurrence count: the bridge identifies the
subscription as soon as a frame reads the bound plate (identity needs no confidence),
baselines openOccurrenceCount, then each tick AND before emit checks if it moved. If a
credential closed/opened an occurrence mid-poll, the subscriber already transacted →
abort, don't emit. New public SubscriptionFlow.openOccurrenceCount(). Bounded loop is
unchanged (ANPR_POLL_WINDOW_MS=8000 cap; never infinite).
+1 test (credential transacts mid-poll → no double-act); 170 server tests green.

A tiny stdlib HTTP server that logs every request (source IP, method, path, full
body, JPEG part stripped) to verify whether a Hikvision camera actually POSTs its
Alarm Server events — independent of our app's parsing/acceptance. It cracked the
2026-06-27 "auto-exit" investigation: proved the exit camera was sending NOTHING
(corrupt config DB), then later that it sent plain VMD without targetType=vehicle.
python3 test-post-camera-events.py [port] # default 8099
Point a camera's Alarm Server at this host:port; drive a car. A line from the
camera IP = it sends (debug downstream); silence = the camera isn't POSTing.

The ANPR bridge took ONE snapshot at the camera's vehicle-alarm instant — but the
alarm fires as the car APPROACHES, so that frame's plate is small/blurry/half-in-
frame and ANPR returns a low-confidence misread ('111'@0.20). The manual test reads
the SAME car at ~100% because by then it's STOPPED at the barrier, well-framed. So
subscriber auto-exit silently never fired (read below the 0.85 floor → ignored).
Fix (the car-stops-at-the-barrier insight): the bridge now PULLS A FRESH FRAME every
ANPR_POLL_MS (1000) and re-runs ANPR until one clears VISION_ENTRY_MIN_CONFIDENCE, or
ANPR_POLL_WINDOW_MS (8000) elapses (drove off / non-subscriber → give up cleanly).
- One loop per camera (#polling set) — the camera's ~1Hz alarm re-fires JOIN the
running loop instead of spawning N concurrent loops.
- Fresh camera.captureSnapshot each tick, NOT captureSnapshotShared (its 1.5s TTL
would re-serve the same bad approach frame).
- Camera-level debounce stamp moved to AFTER a successful emit (suppresses re-fires
for ANPR_DEBOUNCE_MS once we've acted), not before the loop.
VERIFIED on hardware (DS-2CD1047G3H-LIU exit lane): 7 garbage approach frames →
AA890XX@0.999 at the barrier → signed vehicle_exit. Still advisory + fail-soft; a
barrier never opens on a low-confidence read. anpr-entry.test.ts +1 (poll
escalation low→low→high); 169 server tests green. Documented in
lane-presence-and-anpr-entry + the lpr-camera camera-fault writeup.

The admin needs the device web password (to reach a controller/camera's own web
UI), and it's already stored + sent to this admin-only view (redactSecrets strips
only the machine secrets relay/push pw, NOT webPassword — by design, per the
SECRET_CONFIG_KEYS comment). But the form rendered every `secret` field as a masked
password input with no way to unmask it, so the value was present yet unreadable.
Add a per-field show/hide eye toggle on `secret` inputs. No new exposure: the field
is already admin-gated and the value already reaches the client; this just makes the
intended-visible credential readable/copyable. Machine secrets are redacted
server-side and never arrive, so there's nothing there to reveal. i18n sq+en.
healthCheck only opens the transport (TCP connect / USB open) — it proves the
printer is REACHABLE, not that paper feeds and the head fires. Add a "Print test
slip" action so the admin can physically confirm a printer is live (the new
host-net USB /dev/usb/lpN path, or a network printer).
- server: POST /api/setup/test-print — printer-only, re-merges stored secrets like
/test (so an edited network printer authenticates), creates the device, and pushes
a short slip via the device-agnostic printReport(). Fail-soft: a print error
(paper out, head fault, transport drop) is reported, never a 500. Mirrors the
test-anpr pattern.
- web: testPrint() client + PrintTestResult; a button in the device modal shown for
category=printer, with ok/fail rendering. i18n keys in sq + en (parity holds).
Server 168 tests pass; web + server typecheck clean.
