# Required ----------------------------------------------------------------
# The server refuses to start without a strong JWT_SECRET (>=32 chars).
# Generate one with:  openssl rand -hex 32
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.
#   BACKUP_KEY=
#   BACKUP_KEEP_LAST=7                # keep this many newest backups always
#   BACKUP_KEEP_DAILY_DAYS=30         # plus one-per-day within this window

# Optional ----------------------------------------------------------------
# PORT=3000
# HOST=0.0.0.0                 # interface to bind. 127.0.0.1 = loopback only.

#
# Auth-cookie Secure flag. FAIL-SAFE: cookies are Secure (HTTPS-only) BY DEFAULT —
# you only ever opt OUT, never in. Set COOKIE_SECURE=0 for a plain-HTTP deployment
# (e.g. the LAN appliance serving the SPA same-origin over http, where a Secure
# cookie would never be sent and would lock operators out). Local dev over
# http://localhost MUST set this (the dev .env does). Leave unset in any TLS deploy.
# COOKIE_SECURE=0

# Recycle bin retention: a soft-deleted user/role/subscription/plan/tariff is auto-purged
# this many days after deletion (a 6-hourly sweep). Default 30. Set 0 to keep deleted
# items forever (manual purge only). See wiki/concepts/soft-delete.md.

# Comma-separated extra origins allowed to open the booth WebSocket (/api/ws).
# In dev, set the Vite SPA origin. Same-origin is always allowed without this.
# The Tauri DESKTOP shell loads from tauri://localhost (Linux may also send
# http://tauri.localhost), which is NOT same-origin with the backend — add both
# so the desktop app's live feed connects. See apps/desktop.
# To open the dev SPA from another LAN device (phone over wifi), Vite must bind
# 0.0.0.0 (vite.config.ts) AND the host's LAN origin must be listed here, e.g.
# http://10.0.10.203:5173 — the WS handshake's Origin is that LAN address.
WS_ALLOWED_ORIGINS=http://localhost:5173,tauri://localhost,http://tauri.localhost

# Vision / ANPR (optional) -------------------------------------------------
# OFF by default. The Node SERVER's view of the vision microservice (apps/vision),
# which runs as a separate process with its OWN apps/vision/.env. Both sides share the
# VISION_ prefix but are different processes — keep the two .env files separate.
# See wiki/entities/opencv-anpr-service.md "Configuration".
# ANPR rides the entry/exit snapshot (button / QR / RFID triggers it) — no polling.
# VISION_ENABLED=1                       # master switch — nothing runs without it

# VISION_TIMEOUT_MS=1500                 # per-request cap so a slow call can't hang the lane
# VISION_MIN_CONFIDENCE=0.5              # advisory confidence floor; keep in sync with the service
#
# ANPR subscriber-entry bridge (anpr-entry.ts): a subscriber's plate, read off a lane
# camera's vehicle detection, admits them through the gated SubscriptionFlow. Opt-in per
# camera (the camera's config.anpr checkbox in Setup); the camera must be BOUND to a relay.
# VISION_ENTRY_MIN_CONFIDENCE=0.85       # stricter floor for a BARRIER-driving read (near-miss → falls back to card/QR)
