J3vbandClaude Fable 5 fb04a579c4 fix(docker): ship /app owned by the runtime uid; run the boot-smoke in CI too (#1378)
* fix(release): give the Docker boot-smoke a writable /app, and run it in CI

The v1.2.0-alpha.3 release run died at "Boot-smoke Docker image": a bare
`docker run` of the distroless image has nowhere the uid-65532 server can
write — /app is root-owned, and the VOLUME /app/data anonymous volume is
created root-owned too — so config.Load failed on "writing default config:
open config.yaml: permission denied" and the container exited. Real
deployments bind-mount config.yaml and data/, which is why the image itself
is fine.

Move the smoke into Server/scripts/docker-smoke.sh, run the container with
`--tmpfs /app --tmpfs /app/data` (Docker's tmpfs default mode is 1777, so
the non-root server can write both), and call the same script from ci.yml's
docker-build job — loading the image it already builds — so the smoke is
exercised on every PR to main instead of for the first time at tag time.

* fix(docker): ship /app and /app/data owned by the runtime uid so a bare run boots

The tmpfs approach did not survive CI: runc re-applies the underlying
directory's mode to a tmpfs mounted over an existing path, so /app stayed
root:755 and the write still failed. Fix the image instead of the harness:
stage /app/data in the builder, chown it to 65532, COPY --chown it into the
distroless stage before WORKDIR. Docker seeds the VOLUME's anonymous volume
from that image dir, ownership included, so `docker run <image>` with no
mounts now boots and answers /health — which is also the contract the smoke
should be testing, so it goes back to a bare `docker run`.

J3vbandClaude Fable 5 f5faf82a60 infra: observability, backups, guardrails, and deployment hardening (#1376)
* docs: add infrastructure roadmap plan

Records the verified recommendations from an infrastructure review in three
tracks: raising the single-instance ceiling, cheap seams for a possible
multi-instance future, and ops hygiene. Includes explicit anti-recommendations
and sequencing. Security-sensitive detail is intentionally excluded per
docs/security.md.

* feat(server): real health checks and saturation metrics

/api/v1/metrics now exposes signals that were already computed in memory but
never surfaced: reconnect replay tier hits, event-persister counters, SQLite
writer-pool wait stats, aggregate per-client backpressure counters (including
previously invisible low-priority drops), and permission-cache hit/miss.

/health now returns a real verdict: hub dispatch-loop liveness, a bounded
database ping, and a free-disk check, returning 503 with a subsystem reason
when degraded. Checks are cached so the unauthenticated endpoint cannot
amplify load. The hub's panic breaker now exits the process so a supervisor
can restart it, instead of leaving broadcast delivery silently dead while
clients still appear online.

OTel instruments that were declared but never recorded are now wired
(ws_active_connections, ws_broadcast_latency_seconds, ws_messages_total,
ws_events_dropped_total, voice gauges) or removed (db_query_duration_seconds).
Also corrects the docs/api.md description of broadcast_drops, which counts
hub-queue overflow, not client send-queue overflow.

* feat(server): implement scheduled backups, retention, and backup verification

The backup_schedule and backup_retention settings have existed in the admin
panel and API since the initial schema but were never read by any code. The
15-minute maintenance loop now enforces them: a scheduled backup is taken
when the newest backup on disk is older than the schedule interval (manual
backups reset the clock), and retention prunes backups older than the
configured days while always keeping the newest one.

Backups are now verified with PRAGMA integrity_check immediately after
VACUUM INTO (a failed backup is removed rather than listed as restorable)
and again before a restore may overwrite the live database. A failed VACUUM
INTO also cleans up its partial output file — but never a pre-existing one.

The backup directory is configurable via a new backup.dir key (default
data/backups) so operators can point backups at another disk or an off-host
mount, mirroring the SetDatabasePath plumb.

Restore-handler tests now use real SQLite fixtures (the integrity gate
correctly refuses text files) with the mid-copy failure injected through a
test-only copy hook. Also adds audited gosec suppressions to the Windows
disk-free syscall added in the previous commit, which the Windows lint leg
flagged.

* feat(server): capacity and failure-mode guardrails

- server.max_ws_connections: optional cap on concurrent WebSocket clients,
  checked before the upgrade with a 503 + Retry-After; rejections are counted
  and exposed as ws_conn_rejects in /api/v1/metrics.
- Single-process database lock: an OS-level advisory lock (flock / exclusive
  handle) beside the SQLite file makes a second server process fail fast with
  a clear message instead of silently fighting the first over process-local
  state. A bounded retry covers the self-update/restore restart handoff, and
  the lock mechanism failing (e.g. network filesystems) only warns.
- Disk-space awareness: boot-time warnings for the data and backup volumes,
  plus a disk_free_mb metrics field, via a small cross-platform diskutil
  package (already used by /health).
- Upload storage failures: storage.Save now marks server-side filesystem
  failures with a sentinel (storage.ErrIO); handlers return 507 for those
  instead of blaming the client with a 400, and the emoji route stops echoing
  raw storage errors (which embed absolute paths) into responses.
- Unknown config keys now warn at startup — a typo like admin_alowed_cidrs
  previously kept the default silently while the operator believed the
  setting changed. Never fatal: newer servers tolerate older configs.
- Admin settings honesty: the three stored-but-inert settings (server_icon,
  max_upload_bytes, voice_quality) are shown read-only with a note pointing
  at the real config.yaml keys, instead of pretending to apply.

* perf(db): write-path efficiency and capacity knobs

- channel_focus/mark_read now skip the read-state UPSERT when the stored row
  already matches (same last_message_id, no mentions) — refocus events fire
  at up to 10/s/user and every no-op write still occupied the single SQLite
  writer connection. The extra existence check runs on the reader pool, which
  doesn't serialize. Same shape as the session-touch throttle.
- DeleteExpiredSessions is now sargable: migration 031 normalizes legacy
  expiry formats to the RFC3339-Z layout the server writes and indexes
  expires_at, replacing the strftime full-table scan that ran on the writer
  every 15 minutes.
- Boot-time ANALYZE runs only when a migration actually applied; unchanged
  schemas get the cheap PRAGMA optimize instead (which also covers
  crash-restarts that never reached the shutdown optimize).
- The read/write SQL router gets a table-driven test with explicit expected
  values (INSERT ... RETURNING must hit the writer despite being :one).
- New knobs, all defaulting to current behavior: database.max_readers,
  security.auth_rate_limit_multiplier (for shared-NAT communities),
  event_persistence.replay_ring_size and replay_cold_limit.

* fix(server): shutdown lifecycle ordering

- The event pruner and maintenance loop are now joined (bounded) before the
  database closes: bgCtx cancellation used to run AFTER database.Close via
  LIFO defers, contradicting its own comment, and neither goroutine was ever
  waited on — a mid-tick scheduled backup or prune could still hold the
  writer while the pool tore down. StartEventPruner returns a done channel
  with the same join contract EventPersister.Stop already had.
- srv.Shutdown now runs before hub.GracefulStop, so in-flight HTTP handlers'
  broadcasts still reach a live hub and the event persister instead of
  vanishing from the replay/event store across a restart. Shutdown does not
  wait on hijacked WebSocket connections, so the swap adds no delay.
- GracefulStopContext threads the 30s shutdown budget into the hub: the 5s
  client-notice window (matching the countdown clients are shown) ends early
  when the budget expires, and is skipped entirely when nobody is connected —
  early-return startup paths and idle servers no longer sleep 5s for an
  audience of zero.

* build(deploy): systemd unit, compose hardening, boot-smoked releases, CI polish

- deploy/owncord.service: hardened systemd unit template with the two
  verified caveats encoded (install dir stays writable for self-update under
  ProtectSystem=strict; CAP_NET_BIND_SERVICE for ACME's :80), plus a
  'Linux (systemd)' deployment docs section — the Linux service story was
  previously 'Docker or nothing'.
- New 'Reverse Proxy Topology' docs section with a working nginx snippet and
  the correct signaling-vs-media distinction: /livekit/* is already proxied
  by the server, only WebRTC media ports must be directly reachable.
- docker-compose: log rotation, commented resource limits, and a healthcheck
  backed by a new 'chatserver healthcheck' subcommand (the distroless image
  has no shell) that probes /health without config side effects.
- release.yml: a concurrency group (queue, never cancel), and boot-smoke
  gates — the freshly built server binaries and the Docker image are cold
  booted and probed healthy BEFORE anything is signed or pushed. The release
  feed drives signed self-updates, so a binary that compiles but dies on
  boot previously would have shipped itself to every auto-updating instance.
- ci.yml: client-check/client-tests move to ubuntu with the reasoning
  recorded (no win32 code paths, LF enforced repo-wide); admin-e2e gets a
  written graduation criterion instead of an open-ended non-blocking status.
- docs: Tailscale guide notes the CGNAT range vs the default admin CIDRs;
  architecture overview records presence/voice state as the fifth
  single-instance blocker and the macOS client scope decision.

* perf(server): measured load tooling, narrowed invalidation, presence coalescing, storage and CIDR seams

- Fix scripts/k6/ws-load.js against the real wire protocol: envelope-wrapped
  frames, correct message types (typing_start, presence_update), the correct
  /api/v1/ws path, and thresholds that fail a run where nobody authenticated
  or went ready — the script had drifted to pre-envelope framing and reported
  100% green while every auth failed on the first frame. A new
  workflow_dispatch-only load-baseline workflow boots a real server, seeds
  users through the setup/invite APIs, runs the script, and uploads the k6
  summary plus a metrics snapshot for before/after comparison.
- Role-scoped channel-override changes now evict only the affected role's
  members from the permission cache (fail-safe: unreadable member list still
  flushes everything). InvalidateAll here repopulated every connected user —
  two reads each — synchronously inside the admin request via
  RefreshChannelVisibility, a stampede that scaled with total population
  rather than the role's size. Same pattern the per-user override endpoints
  already used.
- Connect/disconnect presence broadcasts now pass through a 300ms latest-wins
  coalescer (QueuePresence): each un-coalesced presence change is a sequenced
  global broadcast (an O(clients) fan-out under seqMu), so a reconnect storm
  fired O(users) of them from the connect critical path. A flap inside the
  window collapses to its final state; the wire format, seq ordering, and
  replay behaviour are unchanged, and the delivery path (BroadcastPresence)
  is untouched.
- Storage seam: api handlers now consume a FileStore interface (consumer-side,
  same pattern as service.Store) with Open returning a seekable storage.File —
  writing down the contract (range-request seeks included) an alternative
  backend would have to meet, without building one.
- The metrics surfaces and the LiveKit webhook/health endpoints get their own
  allowlist keys (metrics_allowed_cidrs, livekit_webhook_allowed_cidrs, both
  defaulting to admin_allowed_cidrs), so a central Prometheus scraper or an
  externally-hosted LiveKit no longer requires widening the admin panel's
  perimeter. Startup now also warns when admin_allowed_cidrs is customized
  while trusted_proxies is empty — behind a proxy or container network the
  check would otherwise compare the proxy's private address, not the client's.
- The container healthcheck probe now PINS the server's own certificate from
  disk (VerifyConnection, exact-match) instead of skipping TLS verification,
  addressing the CodeQL finding on the previous commit; WebPKI verification
  is used when no local cert exists (ACME).

* fix(server): address self-review findings on the hardening branch

Seven fixes from a high-effort review of the full branch diff:

- healthcheck CLI now works under tls.mode acme: it overrides ServerName
  with the configured domain for WebPKI verification instead of pinning a
  cert that doesn't exist (or is stale) in that mode. Previously an ACME
  deployment's container healthcheck failed forever.
- /health pings the READER pool (new db.PingRead): the writer ping queued
  behind a scheduled backup's VACUUM INTO and reported the server degraded
  for the whole backup — which an autoheal watchdog would turn into a
  nightly mid-backup restart.
- /health runs its cached checks under context.WithoutCancel so a probe
  that disconnects mid-request cannot poison the shared cache with a false
  degraded verdict for the next 5 seconds.
- The token CLI uses a new db.OpenShared that skips the single-process
  lock: minting a token against a running server is safe under WAL and was
  a documented workflow the lock had broken.
- The per-user TOTP failure cap is no longer scaled by
  security.auth_rate_limit_multiplier — that knob exists for per-IP limits;
  scaling the only cross-IP brute-force defence multiplied an attacker's
  distributed guess budget. Mirrors the unscaled per-user login threshold.
- A direct presence_update now drops the user's queued entry in the
  connect/disconnect coalescer, so a stale connect-time presence can no
  longer flush 300ms later over the user's fresher chosen status.
- The scheduled-backup filename collision loop breaks on any stat error
  and bounds its suffix probing, instead of spinning the maintenance
  goroutine forever on a persistent EACCES.

* test(admin): real SQLite fixture for the merged Close-failure restore test

TestHandleRestoreBackup_RestartsWhenCloseFails arrived from main (#1375)
with a plain-text backup fixture; this branch's restore handler verifies
backups with integrity_check before touching the live database, so the text
fixture was (correctly) refused with 400 before the Close-failure branch
under test was reached. Use a real backup via BackupToSafe, matching the
other restore tests.

J3vbandClaude Fable 5 6afa9e974c refactor(server): thread context.Context through the db layer and all callers
Fixes all 109 golangci-lint findings (106 contextcheck, 1 gocritic,
2 gosec) that accumulated after D2 wired dbgen (whose queries take ctx)
under ctx-less db.DB wrappers while CI lint was quota-dead. No nolint
comments added; every finding fixed by genuinely threading context.

- db: all 138 hand-written db.DB methods take ctx first; the dbCtx()
  Background shim is deleted; raw Query/QueryRow/Exec/Begin use their
  Context variants; the four redundant ctx-less passthroughs removed.
  db.Auditor/WriteAudit gain ctx.
- Seams: permissions.Checker (DB iface, HasChannelPerm,
  RequireChannelAccess) and the service.Store interface mirror the new
  signatures (ws.EventStore and plugin.PluginStore already did).
- Callers: api/admin handlers use r.Context(); ws per-message paths use
  the connection ctx via DispatchV2; hub loops and startup wiring use
  context.Background(); service methods thread ctx where they have one
  and Background where no ctx exists. Public service surface reached by
  ctx-holding chains (PermissionService.HasChannelPerm/GetRoleForUser/
  RequireChannelAccess, message/dm/block/invite/profile methods) is now
  ctx-first.
- Detached (context.WithoutCancel) where cancellation would break an
  invariant, found by a 3-lens adversarial review of the diff:
  * voice-leave background retries (a dead webhook/connection ctx killed
    retry 2 before it ran, leaving ghost capacity-holding voice rows)
  * rollbackVoiceJoin's compensating delete (its trigger IS the cancel)
  * post-2FA-change DeleteOtherSessions and logout DeleteSession (the
    security tail of a committed change must not die with the request)
  * all api/ws audit writes (a banned user could suppress their own
    login_blocked_banned row by aborting the request mid-bcrypt)
  * admin backup VACUUM INTO (an interrupt left a truncated .db that
    the backup list presented as restorable)
  * post-commit message/edit refetches (a committed message must still
    fan out when the sender disconnects)
  * hub settings-cache refresh (one dead connection could pin stale
    values for the 30s TTL)
- gocritic rangeValCopy fixed (index iteration); gosec G306 excluded in
  config with justification (generated source must stay world-readable)
  instead of flipping genprotocol output to 0o600.

Verified: gofmt/vet, all four build-tag variants, full suite, deadlock
pass, full -race pass, golangci-lint 0 issues uncapped.

Claude 2e7a80171b feat(server,client): protocol codegen + audit quick-wins batch
Protocol codegen (decision D4, audit A-2026-07-08):
- Add docs/protocol-schema.json as the real single source of truth for
  WS message-type constants, making the long-standing 'generated from'
  comment in both constant files true.
- Add Server/scripts/genprotocol, a generator emitting both
  Server/ws/message_types.go and Client .../lib/protocolTypes.ts
  (constants byte-for-byte value-identical to before; only headers,
  ordering alignment, and provenance comments changed).
- Add make protocol-generate / protocol-verify and wire protocol-verify
  into CI next to sqlc-verify.

Quick wins (decision D8):
- admin: log LogAudit write failures in the backup handlers instead of
  discarding them (prior audit #10).
- api: fix self-contradictory upload Cache-Control to 'private,
  no-cache' per remediation plan W3-4; drop the now-unused
  fileCacheMaxAgeSeconds constant; update test.
- ws: route the hub settings cache through db.GetSetting instead of
  inline SQL.
- ws: fix a latent data race — main.go wires SetEventPersister and
  SetEventStore after NewRouter has already started the hub Run loop,
  which reads those fields on the broadcast/replay paths. They (and
  pluginSink, which one test sets post-Run) are now atomic pointers;
  the remaining pre-Run-only setters reject late calls with an error
  log instead of racing silently.

Update the audit closure table and decisions doc statuses accordingly.
