feat(carwash): entry-stream sampling for the review outbox; park-2 wired to the collector
The wash stream is small; the entry camera photographs every car in exactly the view the
classifier is trained on. The booth can now queue entry vehicle reads as pure training
material — crop + the camera's class, no order, no operator, no category.

- Core announces every vehicle read (deviceEvents.emitVehicleRead from snapshot.ts); the
  Car Wash module listens, samples entry reads in-process (sampleEntry: exactly one in N)
  and queues them (enqueueEntry). CARWASH_REVIEW_ENTRY_SAMPLE=N; 1 = every entry (storage
  and bandwidth are not the limit — user); 0/unset = off. Forwarded by compose.
- Packages carry kind: "wash" | "entry". Collector: kind column, entry meta validated
  without the operator fields, review screen shows an entry sample as such, export has a
  kind column, operator agreement computed from wash items only. Setup line shows
  "1 in N entries sampled"; status carries entrySample.
- komodo: park-2's four review lines enabled (collector URL by Netbird DNS name, booth-2,
  the shared per-booth secret, every entry sampled) — the collector is up on the overlay.
- Tests on both sides. Wiki: vision-review-outbox (entry stream + the internet-feed
  assessment), log.

# Copy this file to `.env` (same folder: apps/server/.env) and fill it in.

JWT_SECRET=
# Dedicated HMAC key for signing the append-only event ledger (>=16 chars).
# Generate with: openssl rand -hex 32
# If unset, the server falls back to JWT_SECRET (logged as a warning) — fine for
# dev, but set a dedicated key before production. Events store the key that signed
# them (keyId), so verifyChain still validates a chain that spans a key change.
EVENT_SIGNING_KEY=
# On-site encrypted DB backup (durability for the signed ledger). A daily timer + an admin
# "back up now" button write a consistent, AES-256-GCM-encrypted copy to the target. The
# TARGET DIRECTORY is chosen by the admin in the UI (Setup → Backup) and stored in the DB —
# NOT here. Only the encryption KEY is an env secret. RESTORE is an out-of-band runbook action,
# not a console call. See wiki/concepts/backup-recovery.md.
#
# Dedicated backup-encryption key (>=16 chars), SEPARATE from EVENT_SIGNING_KEY so it can
# rotate without fracturing the signed chain. Generate with: openssl rand -hex 32
# Escrow it offsite (alongside EVENT_SIGNING_KEY) — recovery needs both, and neither is ever
# stored inside the backup it unlocks. Backups stay a no-op until BOTH this key and an in-UI
# target directory are set. The target directory AND retention (keep-last / keep-daily) are
# admin-chosen in the UI (Setup → Backup), NOT env — only this key is an env secret.

# blank = every registered module (parking,validation,carwash) — a DEV convenience. In
# Docker, docker-compose.yml forwards it with a default of parking,validation, so a booth
# is never entitled to a module its Komodo stack env does not name. Required modules
# (parking) are always on. See wiki/decisions/venue-modules.md.

# Car Wash review outbox (wiki/concepts/vision-review-outbox.md) -------------------------
# The operator's category choice is a hypothesis: each wash order with a vehicle read queues

# over the private overlay (Netbird). All three or off. URL = the collector's ingest endpoint
# (reachable only over the overlay); TOKEN = this booth's own bearer token; BOOTH_ID = a
# pseudonymous label the reviewer maps to a site (NEVER the site name — it travels with every
# item). Set in the Komodo stack env, per booth. Nothing is queued while off.
