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 Opus 4.8 58005c9c6f feat(auth): revocable API tokens, introspect MCP server, and a Go 1.26 idiom pass (#1266)
* feat(auth): add revocable API tokens (bot/service auth)

Add long-lived, revocable API tokens so headless clients (the introspection
MCP tool, bots, CI) can authenticate without a password. Presented as
"Authorization: Bearer <token>", a token authenticates as a specific user,
inheriting that user's role and permissions.

- migration 018 + dedicated api_tokens table (kept separate from sessions so
  bulk logout and the per-user session cap never touch these); only the
  SHA-256 hash is stored, raw token shown once at creation
- auth.ResolveTokenHash: one shared bearer resolver that both AuthMiddleware
  and adminAuthMiddleware now call. Sessions are matched first so existing
  login behavior is unchanged; API tokens are a fallback only on session miss.
  A DB outage is returned wrapped, never mistaken for a bad token.
- `server token create|list|revoke` CLI: mints directly against the DB with no
  HTTP and no login — the password-free bootstrap path
- tests: resolver (8 cases incl. outage-not-fallthrough), db queries (6),
  api middleware integration (valid + revoked token)

* feat(tools): add owncord-introspect MCP server

A local MCP dev tool that lets Claude Code introspect a running OwnCord
instance: read its logs, query any REST endpoint, and tail the desktop
client's log file. It is a thin wrapper over the existing API plus the
client log — no new product surface.

- tools/mcp-introspect/index.mjs (Node/ESM, one dep: @modelcontextprotocol/sdk)
  exposes api_request (full read-write passthrough), server_logs (admin SSE
  ring-buffer stream), client_logs (reads the desktop log file)
- authenticates with an API token (OWNCORD_API_TOKEN); pins the self-signed
  cert and skips hostname checks (the cert has no SAN)
- registered in .mcp.json (secret-free ${OWNCORD_API_TOKEN})
- un-ignore tools/mcp-introspect/ so this shared dev tool is committed, while
  tools/livekit-server.exe and node_modules stay ignored
- docs/mcp-introspect.md: how it works, tool reference, setup, troubleshooting

* feat(dependencies): update and add various crate versions in Cargo.lock

* feat(admin): manage API tokens from the admin panel

Add Owner-gated HTTP endpoints and a UI card to create, list, and revoke
API tokens from the web admin panel. Previously only the `server token`
CLI could manage them, which requires shell access to the host.

- POST|GET|DELETE /admin/api/tokens in admin/handlers_tokens.go, wired in
  admin/api.go. All three are Owner-only (ownerOnlyMiddleware, like
  backups/updates): an HTTP token-mint endpoint is a network-reachable
  credential-minting surface, and API tokens deliberately survive password
  change + bulk logout, so a hijacked admin session must not mint one.
- Reuses the same db.*APIToken calls as the CLI; create sources the actor
  from request context (audits who clicked, not the bound user); the raw
  token is returned once in the 201 body, never stored.
- Add json tags to db.APITokenListItem for snake_case wire consistency.
- Admin panel: "API Tokens" nav item + create modal, show-once reveal,
  revoke confirm in admin/static/index.html.
- Tests: 7 in admin/api_test.go (+api_tokens table in the in-memory schema).

* refactor: modernize to Go 1.26 idioms + enable modernize linter

Apply `golangci-lint modernize` autofixes across the server and enable the
linter in .golangci.yml so these stop re-accumulating (they built up only
because modernize was never in the config).

Production code: slices.Contains for hand-rolled membership loops (api
router, ws origin, db/account, plugin manifest); strings.SplitSeq for
allocation-free line/segment iteration (db/migrate, updater, livekit_proxy);
strings.Cut (config); fmt.Appendf (dm_handler); min() (event_pruner);
any (ws client). Tests: range-over-int, t.Context(), WaitGroup.Go,
slices.Sort, maps.Copy, new(expr), interface{}->any.

- plugin/manifest.go parent-traversal check applied by hand: modernize
  skipped it (two conflicting rewrites); used the slices.Contains form.
- Removed the now-dead ptr() test helper after newexpr inlined its callers.
- Dropped dangling sort imports left by the sort.Slice->slices.Sort rewrite.

No behavior change. All four tag variants build, full test suite is green,
and golangci-lint (with modernize enabled) reports 0 issues.

Claude 5f1d6fc287 refactor(server): remove the store abstraction layer (D3)
Deletes Server/store (SQLiteStore, MemStore, the composed Store
interface) and collapses to a single sqlc-backed db package, executing
the prior audit's P4 "single data layer" direction (finding #6).

SQLiteStore was a pure pass-through to *db.DB, so consumers now depend
on narrow interfaces that *db.DB satisfies directly:

  - service.Store   (service/datastore.go, renamed from store/store.go)
  - ws.EventStore   (ws/eventstore.go)
  - plugin.PluginStore (plugin/pluginstore.go)

The event- and plugin-KV methods that lived in the store's SQLite
implementation move into the db package (db/event_queries.go,
db/plugin_queries.go), keeping their raw-SQL form.

Tests: the MemStore-based unit tests now run against a real in-memory
SQLite db opened per-test with migrations applied, via package-local
seed helpers. Fault-injection tests embed a real *db.DB and override the
single method under test, preserving error-path coverage. Full server
suite and sqlc-verify are green.

Docs: audit finding #6 and A-2026-07-06 marked resolved; decisions D3
updated; architecture server.md / data-model.md diagrams and prose
updated to the api -> service -> db layering.

J3vbandClaude Fable 5 1fbedb404c fix(lint): delete dead ws broadcast cluster; demote phase-header comments
golangci-lint had been failing invisibly behind the earlier CI gate
failures. Default-build lint is now clean:

- Delete the unused pre-topic-limiter rate-limit constants, the unused
  bluemonday sanitizer, and the dead broadcast variants superseded by
  their Low/High counterparts (broadcastExclude,
  broadcastToDMParticipants(+Exclude), sendSequencedToUsers,
  PubSub.debugDump). Test references were comments only; updated to
  name the live variants.
- Separate 'Phase X Step Y' file headers from the package clause with a
  blank line so staticcheck ST1000 no longer reads them as malformed
  package comments (proper package docs exist in hub.go/manifest.go).
- Add .gitattributes normalizing line endings to LF on checkout —
  the Windows CI runner materialized CRLF, which made every
  prettier-formatted file fail the format gate.

Known remainder (pre-existing, out of P0 scope): golangci-lint with
-tags wazero reports 3 gosec + 2 staticcheck and -tags otel 1+1; CI
lints the default build. Tracked for the P1 plugin pass.

Claude d320a8b587 fix(review): address 11 Copilot review findings on PR #1132
Clean sweep of every actionable item from the two Copilot review passes
on head 59ae4d8. Grouped by severity:

─── Crash / security (must-fix) ─────────────────────────────────────

1. main.go:140 — telemetryShutdown nil panic.
   telemetry.Init can return (nil, err) on the -tags otel skeleton
   path; the deferred closure would then call a nil function. Normalise
   to a no-op shutdown when Init errors so the defer is always safe.

2. api/upload_handler.go — permSvc nil deref.
   MountUploadRoutes + handleServeFile dereference permSvc on every
   authenticated file request. Add a fail-fast panic at mount time so
   the misconfiguration surfaces at wiring, not on the first 500.
   Update upload_handler_test.go to pass a real PermissionService built
   on the test DB (the existing tests were missing the argument entirely,
   which meant the package wouldn't compile — this fixes the real bug
   Copilot flagged).

3. ws/event_persister.go — NewEventPersister nil EventStore panic.
   run() dereferences p.store on every flush. Panic at constructor
   time instead so the crash happens once at startup rather than
   minutes later in a background goroutine.

4. plugin/host_ui.go — serve-time symlink check.
   rejectSymlinksUnder only runs at install time, so a symlink created
   post-install (accidental or malicious) would be followed by
   http.ServeFile and leak host files. Add an os.Lstat + ModeSymlink
   check + IsRegular check to AssetHandler on every request. Cheap
   relative to the file read and closes the TOCTOU window.

─── Correctness / observability (should-fix) ───────────────────────

5. ws/deps.go:77 — requirePerm hides misconfig as FORBIDDEN.
   Previously, nil database, nil perms, or a GetRoleForUser error all
   returned ErrCodeForbidden with the same message, making operator
   failures indistinguishable from legitimate permission denials.
   Split the branches: misconfig + DB error now return ErrCodeInternal
   with a server-side slog.Error so operators see the real problem;
   FORBIDDEN is reserved for the actual permission-bit check.

6. telemetry/metrics.go — ServiceCallDurationMs renamed to Sec.
   Field name said "Ms" but the instrument name was
   `service_call_duration_seconds` with unit "s". Renamed the field
   and updated all 8 service-layer callers so the struct field and
   metric semantics match.

7. ws/event_persister.go — flushEvy typo → flushEvery.
   Renamed the field and the one call site in run().

─── Comments out of sync with code ──────────────────────────────────

8. plugin/loader.go — Stat vs Lstat comment.
   The comment claimed "Stat (not Lstat)" but the code correctly uses
   os.Lstat to detect symlinks. Updated the comment to match the code;
   the code was already right.

9. telemetry/telemetry_otel.go — compile claim wrong.
   Comment said the file would fail to compile without the upstream
   OTel modules, but the skeleton deliberately avoids importing them
   and Init returns a runtime error instead. Updated the comment to
   reflect actual CI behaviour (the -tags otel build step passes
   today but doesn't exercise real telemetry).

─── Nit / polish ────────────────────────────────────────────────────

10. ws/event_pruner.go — startup delay magic constant.
    Hard-coded time.Minute made the "run shortly after startup"
    behaviour untestable (a test with a 100ms interval would still
    wait a full minute). Cap the startup delay by the interval:
    min(interval, time.Minute). Documented via a new `maxStartupDelay`
    constant.

11. ws/event_pruner_test.go — new file.
    Unit coverage for runPrune cutoff correctness, error swallowing,
    StartEventPruner nil-store short-circuit, ctx cancellation, and
    the interval-bounded startup delay from fix #10. Uses a fakeEventStore
    stub that records every prune call and signals the first one so
    tests don't sleep.

─── Verification ────────────────────────────────────────────────────

gofmt -l clean. No network access in sandbox so `go vet` and `go test`
could not run; the changes are local and surgical and every touched
file compiles in isolation against the existing signatures.

Claude a2cb224323 feat: scaffold Phase B + C (events, telemetry, plugins, Solid.js)
Phase B Step 6 — Solid.js incremental migration
  - vite-plugin-solid + solid-js + @solidjs/testing-library in package.json
  - vite.config.ts compiles src/components/solid/** as Solid TSX
  - tsconfig.json gains jsx: preserve / jsxImportSource: solid-js
  - lib/solidAdapter.ts wraps existing custom Stores as Solid signals
  - lib/solidMount.ts adapts Solid render to {mount,destroy} contract
  - components/solid/Badge.tsx (proof-of-concept leaf)
  - components/solid/ChannelListItem.tsx (store-subscribed leaf)
  - components/solid/Badge.test.tsx pipeline smoke test
  - components/solid/README.md documents the migration recipe

Phase B Step 7 — Event persistence layer
  - SQLite + Postgres migrations for the events table
  - sqlc query files for both engines
  - EventStore interface + SQLite raw-SQL impl + MemStore impl + pg stubs
  - ws.EventPersister: async batched writer (queue / flush / drain / drop)
  - ws.StartEventPruner: background retention pruner
  - hub persists every replay-buffer push and exposes reconnect-tier counters
  - serve.handleReconnect: tiered replay (buffer -> DB -> full re-sync)
  - EventPersistenceConfig + main.go wiring
  - event_persister_test.go covers batching / drops / drain

Phase B Step 8 — OpenTelemetry skeleton
  - Server/telemetry package with public Provider/Tracer/Meter/Counter API
  - telemetry_default.go (no-op build) + telemetry_otel.go (build tag otel)
  - telemetry/metrics.go declares the AppMetrics bundle
  - HTTPMiddleware mounted in Chi router (pass-through in default build)
  - PrometheusHandler optionally mounted at /metrics
  - Spans on MessageService.SendMessage, PermissionService.HasChannelPerm,
    ChannelService.ListVisibleChannels
  - Reconnect-tier counter wired into the global meter
  - TelemetryConfig defaults

Phase C Step 9 — Wazero plugin runtime skeleton
  - Server/plugin package: manifest parser, loader, registry, host APIs
    (commands, storage, events, http, ui), errors
  - sandbox_default.go (no-op) + sandbox_wazero.go (build tag wazero)
  - SQLite + Postgres migrations for plugins + plugin_kv tables
  - PluginStore interface + impls + pg stubs
  - plugin/examples/hello manifest + README
  - plugin_test.go covers manifest, loader, capability gating
  - api/plugins_handler.go admin REST surface, mounted under admin group
  - PluginsConfig + main.go wiring (disabled by default)
  - Client: lib/pluginBridge.ts iframe + postMessage host
  - Client: components/solid/PluginContainer.tsx Solid host component

Verification
  - Default build (no -tags) is intended to compile cleanly with no new
