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.

J3vbandClaude Fable 5 a4eca1a55a fix(perms): own the server-scoped rule in HasServerPerm and fail closed on override-fetch errors (D13)
Closes audit finding A-2026-07-16, two defects in the same rule:

- permissions.HasServerPerm (admin bypass OR all-of bit test) replaces
  the hand-rolled copies in api.RequirePermission (whose raw test was
  any-of for multi-bit masks) and ModerationService.requireBanPermission.
  RequirePermission's doc comment now states the scope contract: role
  bitfield only, channel overrides deliberately not consulted.
- PermissionService.getOrPopulate and ChannelService.ListVisibleChannels
  no longer substitute an empty override map when
  GetAllChannelPermissionsForRole errors. That silently dropped every
  channel-level deny — and the permission cache then served the degraded
  snapshot for permCacheTTL (30s) across ~25 callers. Both fail closed
  now; admins skip the fetch entirely (they bypass channel checks).
- PermissionService.HasChannelPerm delegates to Checker.HasChannelPermBatch
  and MessageService.GetAccessibleChannelIDs to VisibleChannelIDs — the
  missed fifth D9 site, making that closure true rather than aspirational.
- AuthMiddleware rejects a dangling role_id (GetRoleByID returns nil,
  nil) with 401 instead of putting a nil role in the request context.

Locked by failing-first tests: override-fetch-error denies (cached and
uncached paths), admin-outage skip, multi-bit all-of, channel allow
override must not grant a server-wide route, 403 locks on both
RequirePermission routes, dangling-role 401.

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.

J3vb 670e6e0323 security: harden plugin sandbox stdin and opaque internal errors
- sandbox_wazero.go: explicitly discard plugin stdin via WithStdin to
  prevent WASM modules from reading the server process's stdin fd
- channel_handler.go: replace ErrInternal message pass-through with
  generic 'an internal error occurred' — full error stays server-side
  in slog.Error only
- invite_handler_test.go: update assertions to expect generic message

- Implement PostgresStore EventStore and PluginStore methods in store/postgres.go
- Wire plugin host_events.go EventSink into hub broadcast path (SetPluginEventSink)
- Wire host_commands.go slash-command dispatcher: chat_command V1 handler + hub.SetPluginRegistry
- Add handlers_command.go + handlers_command_test.go for plugin slash-command dispatch
- Add reconnect_db_test.go: TestReconnect_BufferMiss_FallsBackToDBTier (cold-tier DB replay)
- Add otel-up/otel-down Makefile targets; docker-compose.otel.yml + prometheus.dev.yml
- Update PHASE_BC_LOCAL_TODO.md: mark in-session items complete; document remaining network-blocked steps
- Minor fixes: channel_handler access-control, router plugin handler wiring, service span instrumentation

J3vb f962d59cd6 fix: update tests and fix pending-join drain regression for CI
Update LiveKitSession tests to use _state discriminated union instead of
old flat field names (room, currentChannelId, latestToken, etc.) removed
in the state machine refactor. Also fix renderers.test.ts URL resolution
by setting a server host in beforeEach so isSafeUrl can parse relative
attachment URLs in jsdom. Stage all four Go test files so the CI Go job
runs them.

Additionally fix a regression in connectAndSetup's finally block: when a
pendingJoin is queued during a stale-join abort, preserve the connecting
state so handleVoiceToken's drain loop can pick it up rather than losing
it by resetting to idle.

J3vb e35e1b346c fix: encrypt TOTP secrets at rest and filter replay buffer by permissions
M1 — TOTP secrets are now AES-256-GCM encrypted before being stored in
the database. Key is auto-generated on first run (data/totp.key) or set
via OWNCORD_TOTP_KEY env var. Existing plaintext secrets are detected
and returned as-is for backwards compatibility.

M3 — Replay buffer events are now tagged with their channel ID. On
reconnect, the server computes the user's current accessible channels
and only replays events from those channels. Global broadcasts (presence,
voice state, member updates) are always replayed. Falls back to full
ready payload if permission computation fails.

jevb ce4326766a fix: resolve all golangci-lint issues blocking CI server build
Fix 70+ errcheck violations by adding explicit error discards (`_ =`)
for unchecked return values across test helpers and deferred Close()
calls. Remove unused `senderID` field from broadcastMsg and unused
`defaultCleanupMaxWindow` const. Apply De Morgan's law, remove empty
branch, and simplify redundant type declaration per staticcheck.
