- Locks no longer fail open: an unreachable backend throws
LockUnavailableError and withLock skips the run (or opts into running
unlocked, as template seeding does). The lnbits payment poller keeps
polling through an outage, made safe by only sending confirmation
emails when a row actually transitioned.
- Rate limiter INCR+PEXPIRE now runs as one Lua script, self-healing
counters stranded without a TTL.
- Per-email login lockout moves to a Redis-backed store shared across
replicas (in-memory fallback preserved), case-insensitive on email.
- Graceful shutdown on SIGTERM/SIGINT: stop periodic jobs, close the
server, force-close lingering SSE sockets, close Redis.
- Active PING probe backs the health flag; /health reports last ping.
SSE payment streams also poll the DB as a pub/sub-gap fallback.
- Scale compose gains requirepass, maxmemory 256mb with noeviction, and
an authenticated healthcheck; .env.example documents passwords, TLS
(rediss://), and DB-index selection.
- First tests in the repo: vitest + ioredis-mock covering the lock,
rate limiter, and login lockout stores (27 tests).

Split oversized frontend API client, email service, and admin/booking pages into focused modules while preserving import surfaces, and add Redis-backed queues, stale booking cleanup, stronger auth, and scale deployment configs.
