Applied from a deadcode (RTA from mains, all build tags) sweep with
per-symbol adversarial verification:
Deleted (nothing but their own self-tests used them):
- admin.Handler (deprecated since Phase 6; production mounts NewHandler)
plus its two self-tests
- ws.Hub.broadcastVoiceStateUpdate + wrapper + two self-tests (pre-V2
leftover; the live voice_state path is the hub voice routines)
- ws.VoiceLeaveEvent + methods ('retained as scaffolding', never
constructed in production; MsgTypeVoiceLeaveBC stays — live via the
leave routine)
- ws.parseIdentity (production calls parseParticipantIdentity directly;
ParseIdentityForTest now exercises the real parser)
- telemetry.Float64 (String/Int64 are used; the float case is covered by
the otel-tagged internal test, re-addable when a caller appears)
Moved into export_test.go so they leave the production binary (all
callers are same-package tests): the eight ws test-client constructors
and voice/E2EE setters from ws/client.go, admin.SetBackupBaseDir
(new admin/export_test.go), api.SecurityHeaders (test-only wrapper;
production uses SecurityHeadersWithTLS — docs/api.md updated to the
real name). Client.getVoiceJoinToken/setVoiceChID inlined into their
existing ForTest wrappers; TestSetVoiceChID_* self-tests deleted.
Kept after verification: updater.SetBaseURL (11 cross-package test call
sites) and telemetry.resetAppMetricsForInit (live under -tags otel —
untagged deadcode false positive).
Full gate green: gofmt/vet, 4 build-tag variants, full suite, deadlock,
race.

hasChannelPerm resolved permissions from the connect-time role snapshot (c.user.RoleID), so a user reassigned to a lower role kept the old role's voice privileges (CONNECT_VOICE and the SPEAK/VIDEO grants in the LiveKit token) until reconnect. Resolve the current role via GetRoleForUser(c.userID), matching the V2 handlers. (Security scan F5)

Route the four "must mirror" READ_MESSAGES filters — REST
ListVisibleChannels, ws buildReady, reconnect replay
computeAllowedChannels, and hub RefreshChannelVisibility — through a
single permissions.Checker predicate so a drift can never leak a
private channel (audit A-2026-07-07 / backlog item 3).
- add permissions.Checker.VisibleChannelIDs + ChannelRef (skips dm,
fails closed, admin bypass via HasChannelPermBatch)
- delegate the three batch sites; RefreshChannelVisibility uses
HasChannelPerm instead of its inline EffectivePerms copy
- REST/WS agreement test asserting all three sites yield the identical
non-DM set across admin / member-with-deny / denied-everywhere

Three review findings on the #93 feature:
- RefreshChannelVisibility targeted clients by their connect-time role
snapshot; a user whose role changed mid-session was evaluated against the
stale role. Resolve the current role from the DB per client (fail closed).
- Visibility updates are targeted, unsequenced messages, so a client that
disconnected before an override change and later resumed via replay never
converged (stale sidebar until a fresh connect). Track a visibility-change
sequence watermark and force resumes from at/before it onto the
full-ready path.
- The admin SPA interpolated channel/user names into single-quoted JS
strings inside onclick attributes with HTML-escaping only; a name
containing a quote broke out of the string literal (XSS in the admin
panel, reachable by any user allowed to create channels). Add a jsq()
helper (JS-escape then HTML-escape) and use it for every onclick name
interpolation.
Follow-up to #93.

newEmitTestHub and NewHubForTest built raw Hub literals without the
topic rate limiter, so deliverBroadcast panicked on a nil receiver and
TestEmitEvents_ChannelEvent_CallsBroadcastToChannel could never pass.
CI never surfaced it because the pipeline died at govulncheck first.
Wire the limiter exactly as NewHub does; no production nil-guard, since
a nil limiter in production would silently disable rate limiting.

Final in-sandbox completeness pass. Five focused pieces; the remaining
items in PHASE_BC_LOCAL_TODO.md after this commit are all genuinely
local-only (toolchain, network, native deps).
Test coverage (the biggest gap from prior reviews)
- Server/plugin/manifest_test.go — pluginNameRegexp accept/reject table,
validateRelativePath table, oversized version, unknown permission.
- Server/plugin/host_http_test.go — hostAllowed dot-boundary suffix,
empty-entry rejection, case insensitivity, FQDN trailing dot. ipAllowed
table over loopback, RFC1918, RFC4193 (ULA), RFC6598 (CGN), link-local,
multicast, unspecified — both v4 and v6 — plus public-IP accept cases.
- Server/plugin/loader_test.go — rejectSymlinksUnder catches direct and
nested symlinks; scanPluginDirectory rejects a plugin whose entrypoint
is a symlink. Skipped on Windows where symlink creation needs elevation.
- Server/plugin/host_ui_test.go — AssetHandler serves declared files,
rejects undeclared files (404), rejects path traversal, supports nested
asset paths.
- Server/ws/hub_seedseq_test.go — SeedSeq monotonic, never-backwards,
concurrent CAS safety, integration with nextSeq.
- Server/ws/extract_event_type_test.go — table covering happy paths,
control char rejection, escaped quote rejection, length cap (64),
empty/missing/non-JSON inputs.
Plugin install endpoint (closes a real feature gap)
- Server/plugin/registry.go — InstallFromZip extracts a plugin .zip into
a staging directory under cfg.Directory, validates it zip-slip safe
(cleaned-path Rel check), refuses non-regular entries, refuses
symlinks, caps compressed at 16 MiB and uncompressed total at 64 MiB
(each file gated by io.CopyN against the remaining budget). Manifest
is parsed at the staged root, then atomically renamed into the
canonical plugin directory and registered via the existing
installFromDisk path.
- Server/api/plugins_handler.go — POST /install accepts multipart with
one "plugin" file part, http.MaxBytesReader caps the request body,
io.LimitReader caps the in-memory buffer, calls Registry.InstallFromZip,
returns 201 with the new plugin name. The endpoint inherits the Pass 2
admin auth + IP gate (mounted under r.Use(admin.RequireAdminAuth)).
Protocol surface
- Server/ws/serve.go — buildAuthOK now takes replaySource and includes
it in the auth_ok payload as "replay_source": "none" | "buffer" | "db".
Two call sites updated: reconnect path passes the existing local,
fresh-connect path passes "none". Test export updated to pass "none".
CI build-tag matrix
- .github/workflows/ci.yml — three new steps inside server-build-test
build the server with -tags otel, -tags wazero, and -tags otel,wazero.
All three are continue-on-error: true until the upstream OTel and
wazero modules land in go.mod (tracked in PHASE_BC_LOCAL_TODO.md).
Once they do, dropping continue-on-error converts the steps into
hard CI gates against tag-boundary drift.
Documentation
- CHANGELOG.md — new root-level file with curated entries for Phase B,
Phase C, security, and behavioural changes operators must know about
(notably event_persistence.enabled = true by default).
- PHASE_BC_LOCAL_TODO.md — ticks off the install endpoint, the
replay_source field, and the existing event_persistence defaultYAML
entry. The remaining items are toolchain-bound.
After this pass, the in-sandbox completeness ceiling is reached.
Everything still pending requires Go 1.25 toolchain, npm install,
real OTel SDK + wazero modules, sqlc, postgres backend impl, or
tinygo.

When a client focuses a channel, subscribe to its pub/sub topic.
When switching channels, unsubscribe from the old topic first.
This completes the pub/sub integration — channel broadcasts now
route only to clients subscribed to the relevant topic.
https://claude.ai/code/session_01CBFF3r84ywkJRWwuqw8zD8
Idle WebSocket connections only revalidated sessions every 10 sent
messages, allowing revoked tokens to stay connected indefinitely.
Add sweepRevokedSessions() on a 30s ticker that checks all connected
clients against the DB and kicks any with deleted/expired sessions
or banned users.
If GetRoleByID fails or returns nil during WebSocket connect, the
server now disconnects the client instead of serving a permissive
ready payload with all channels visible. In buildReady, nil role is
now treated as zero-access (no channels) instead of full-access.
Updated tests to pass explicit Owner role where channel visibility
is expected.
- voice_join.go: treat GetVoiceState DB error as switch failure instead
of silently proceeding (HIGH: could bypass capacity check)
- voice_leave.go: move ctx to first parameter per Go idiom, remove
nolint:revive directive (MEDIUM: style compliance)
- Update all call sites for new parameter order
- BUG-084: Broadcast filter now delivers channel messages to unfocused
clients (channelID==0) instead of silently dropping them
- BUG-086: leaveVoiceChannelWithRetry retry goroutine respects context
cancellation and hub stop to prevent leaks on shutdown
- BUG-088: Voice channel switch verifies old state is cleared before
joining new channel, preventing capacity bypass on DB failure
- BUG-089: handleFreshConnect RemoveParticipant goroutine checks hub
stop and documents identity-based targeting safety
CRITICAL (5):
- Hub panic recovery now calls h.Stop() after 3 panics (ws/hub.go)
- Ring buffer EventsSince returns non-nil empty slice for current seq (ws/ringbuffer.go)
- PTT event listener stores unsubscribe handle to prevent leak (ptt.ts)
- verifyTotp respects config.allowSelfSigned instead of hardcoding (api.ts)
- ptt_listen_for_key uses spawn_blocking to avoid thread pool starvation (ptt.rs)
HIGH - Server (13):
- TOTP rate-limit checked after body decode; counters reset on success
- TOTP enable returns 409 if already enabled (must disable first)
- Global search pre-computes accessible channel IDs for FTS WHERE clause
- DeleteAccount queries roles by name instead of hard-coded IDs
- BackupToSafe uses absClean in VACUUM INTO
- Voice camera slot uses atomic EnableCameraIfUnderLimit DB method
- readPump snapshots voiceChID before unregister for TOCTOU safety
- Voice join sets state after token send; rollback takes broadcast flag
- Updater download uses probe pattern instead of overflow write
- Webhook checks Authorization header before reading body
- Storage.Save adds fsync and fixes double-close
- Default WS origin denies cross-origin (was: accept all)
HIGH - Client (6):
- WS reconnect uses generation counter to discard stale events
- AudioPipeline uses generation counter against stale worklet callbacks
- Screenshare mute state preserved across reconnect (not full leave)
- handleVoiceToken uses iterative loop instead of unbounded recursion
- store.ts re-entrancy guard with pending update queue
- Notification AudioContext cleaned up on logout
Reviewed by 4 parallel agents across Server Core, Server Realtime,
Client & Tauri, and Security. 55 total findings; 24 CRITICAL+HIGH
fixed here, 31 MEDIUM+LOW tracked in vault backlog (T-265–T-295).
- Video grid: sync stream type attribute on updates, add screenshare data attribute
- Dispatcher: handle voice_token messages, improve video track event handling
- LiveKit session: add video track publication support
- Hub: stale client timeout cleanup, improved voice state management
- Voice join/leave: context propagation, better error handling
- Livekit webhook: structured event handling with room/participant data
- Server DB: voice query improvements, new test coverage
- WS integration tests: expanded coverage for voice and LiveKit flows
- Gitignore: add internal dev tools directory, owncord-server.exe
