Audits what actually has tests, then closes the gaps it found. Full write-up
with before/after numbers in docs/audit-test-coverage-2026-07-25.md.
Measurement first: `go test ./... -coverprofile` (what CI runs) instruments
each package only for itself, so code exercised through another package's
tests reads as uncovered — `service` reported 36.7% against a real 85%. All
analysis here uses -coverpkg=./..., and both views now have Makefile targets.
Features that had zero coverage at every layer:
- user blocking (db + service + the /api/v1/blocks routes)
- auth lockout persistence — the DB round-trip that survives a restart
- plugin install/enable/disable/uninstall and the plugin KV namespace
- event replay bounds (GetMaxEventSeq, PruneEventsOlderThan)
- LiveKit participant_joined webhook (replayed-token guard), the room-service
client, and proxyWebSocket/copyWS
- ws_proxy.rs and livekit_proxy.rs — pure helpers extracted, matching the
existing tofu.rs pattern, so cert-pin and header-injection checks are testable
Gaps that were hidden rather than absent:
- Server/admin reported 0.3% coverage with 307 tests passing. TestSpawnDetached_*
re-execs the test binary; the child inherited GOCOVERDIR and the parent's
stdout, clobbering the profile and printing "[no tests to run]". Now 71.4%,
and CI's uploaded artifact is correct.
- vitest.config.ts excluded 2.2k LOC unexplained, including two files that
already had tests. Trimmed to three entries, each justified inline.
- api.HandleLiveKitHealthForTest re-implemented the handler it claimed to
expose, so eight call sites tested a copy. Added a hook to the real one.
Two bugs found and pinned rather than silently patched: logctx.WithGroup nests
req_id under the group, and drag-reorder.ts takes one listener ref per channel
but releases one per sidebar, so the count never reaches zero.
Coverage: client 92.93% -> 94.87% statements (3371 -> 3572 tests) even after
un-excluding hidden files; Rust 47 -> 74 tests; Go zero-coverage functions
~70 -> 21, with plugin 61->77%, admin 67->86%, db 76->84%, service 85->91%.
Verified: go vet, all four build-tag variants, go test -race, -tags deadlock,
vitest --coverage, cargo test --lib, cargo clippy --all-targets, playwright.

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.

The read side of channel visibility was already complete — channel_overrides
rows deny ReadMessages and every list/focus/send/voice path enforces them —
but nothing could write those rows. Add the missing write path and UI:
- db: UpsertChannelOverride / DeleteChannelOverride / ListChannelRoleOverrides
(roles LEFT JOIN overrides so the UI gets everything in one call)
- admin API: GET/PUT/DELETE /admin/api/channels/{id}/permissions[/{roleId}]
with unknown permission bits masked via the new permissions.AllPerms,
audit logging, and immediate permission-cache invalidation
- ws: Hub.RefreshChannelVisibility sends targeted channel_create /
channel_delete to connected clients after an override change, unsubscribes
hidden clients from the channel topic, and clears their focus. Sent outside
the sequenced replay path on purpose: a replayed channel_delete would be
filtered by the post-change allowed-channel set, inverting its audience.
- admin panel: per-channel Access modal (lock icon) with per-role
"Can access" checkboxes; unchecking writes deny = ReadMessages|ConnectVoice
Known limits (follow-ups): users offline during a revoke keep a stale
sidebar entry until their next fresh connect (server still denies access),
and users already in a voice channel are not kicked when it goes private.

Service level: BAN_MEMBERS refusal (Forbidden even for nonexistent targets
— no id enumeration), equal-rank and owner-target hierarchy refusals,
authorized ban/unban round-trip, self-ban rejection. Admin API level:
equal-rank owner ban 403s, a lower-positioned ADMINISTRATOR cannot ban the
owner, downward bans still work. All existing NewAdminAPI/NewHandler test
callsites now inject a real ModerationService so the production
authorization runs in every PATCH-user test.

Critical fixes:
- Move svc creation in router.go above MountInviteRoutes/MountChannelRoutes
(was used before definition — compile error)
- Restore hasChannelPermREST in channel_handler.go for upload_handler.go
(was removed but still referenced — compile error)
Permission cache invalidation:
- Add PermissionInvalidator interface to admin package
- Wire through NewHandler → NewAdminAPI → handlePatchUser
- Call InvalidateUser(userID) after role changes in admin panel
- Update all admin test files to pass nil as new parameter
Also clarifies WithTx documentation for SQLite single-writer semantics.

The first-run setup POST was vulnerable to cross-site request forgery
because it had no Origin validation. Added isSetupOriginAllowed check
that validates the Origin header against configured allowed_origins.
Requests with a mismatched Origin are rejected with 403. Requests
without an Origin header (same-origin or curl) are allowed through.
Admin panel redesign:
- Rebuild frontend from mockup with Discord-style dark theme
- Stat cards, section cards, role badges, modal system, toast notifications
- All 7 sections: Dashboard, Users, Channels, Audit Log, Settings, Backups, Updates
- Modals replace confirm()/prompt() for all destructive actions
Live server logs (new):
- RingBuffer + MultiHandler tees slog to stdout AND in-memory buffer
- SSE endpoint at /admin/api/logs/stream streams logs in real-time
- Log viewer with level filters (DEBUG/INFO/WARN/ERROR), search,
auto-scroll, pause/resume, copy all, clear
- Color-coded lines by level, source categorization from file paths
Audit log improvements:
- Search filter (actor, action, target, detail)
- Action type dropdown filter
- Copy All and Export CSV buttons
- Instant client-side re-filtering
Console output:
- Switch from JSON to human-readable text format (slog.TextHandler)
- Move startup banner before init logs so it appears first
- #16: Fix golangci-lint issues (unchecked Close(), unused funcs, naming)
- #17: Add KeybindsTab and LogsTab unit tests (19 tests, 81%+ coverage)
- #18: Add rate limiting to chat_edit and chat_delete handlers
- #19: Fix cert mismatch handling via event listener instead of string match
- #20: Validate SHA-256 colon-hex fingerprint format in Rust ws_proxy
- #21: Optimize session+ban check with single JOIN query
- #22: Sort channels by position when redirecting after deletion
- #23: Rename admin test files for clarity
Also fixes ban expiry regression (H-1 from code review) by using
auth.IsEffectivelyBanned() to properly respect temporary ban expiry.
