Audit writes stay best-effort — a LogAudit failure must never fail or abort
the request — but a failed write must no longer be silently discarded. Add
db.WriteAudit(auditor, actor, action, targetType, targetID, detail), which
logs a failed write with actor/action/target context (never the detail
string, which may be sensitive) and never propagates the error.
The Auditor interface is satisfied structurally by both *db.DB and the
service-layer Store, so api/admin/ws/service all reach the helper without an
import cycle. Converts all ~26 call sites from `_ = LogAudit(...)` (and the
two backup handlers' inline `if err` blocks) to db.WriteAudit. Pinned by
db/audit_test.go: failure logged and not propagated, success logs nothing,
detail never leaks.
Resolves the repo-wide LogAudit policy question flagged by the D8 note.

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.

Make 'announcement' a real channel type, resolving the contradiction where
it was documented and offered by the admin API but hard-rejected by the
migration-013 DB triggers.
Model: announcement channels are readable like text channels (same
READ_MESSAGES visibility), but posting is restricted to users with
MANAGE_MESSAGES — no new permission bit, migration, or client permission
plumbing needed.
Server:
- migrations/016: recreate the channel-type triggers to allow
text/voice/announcement/dm.
- service/message.go: checkSendPermission now takes the channel type and
rejects posts to announcement channels from users lacking MANAGE_MESSAGES
(SendMessage + CanPost paths). Added a service test.
- Unread counts: ready-payload builder (ws/serve.go) and
GetChannelUnreadCounts (db) now include announcement channels alongside
text, so they track unread/last-message like text channels.
Client:
- ChannelSidebar renders announcement channels with a megaphone icon
(added to the icon set) instead of the '#' text prefix; they otherwise
behave like text channels (already typed in ChannelType).
Specs + trackers (api.md, protocol.md, schema.md incl. migration 016,
architecture/data-model.md, audit A-2026-07-01, decisions D1) updated.
Verified: go build ./...; go test ./service ./db ./ws ./api ./admin;
sqlc-verify; client tsc + oxlint + prettier clean.

messages/reactions: CreateMessage, GetMessage (messageFromGen mapper),
EditMessage (EditMessageContent), DeleteMessage (SoftDeleteMessage),
AddReaction, RemoveReaction, GetReactions (GetReactionCounts),
SetMessagePinned, UpdateReadState. Retired the obsolete scanMessage.
Kept raw by design (no clean sqlc mapping): FTS search, cursor-paginated
GetMessages/GetMessagesForAPI/GetPinnedMessages, getReactionsBatch,
GetChannelUnreadCounts, GetLatestMessageID (interface{} MAX result).
D2 status: 97 db.DB methods now delegate to dbgen across every domain;
43 raw d.sqlDB calls remain by design (db.go passthroughs, migrate.go,
variable-length IN(), FTS, multi-statement transactions, PRAGMA/VACUUM).
sqlc is no longer dead code — audit A-2026-07-05 resolved. Full rationale
+ the kept-raw list in docs/plans/sqlc-adoption.md.

Convert the auth_queries.go user + session reads/writes and
profile_queries.go to the sqlc-generated layer, adding shared
userFromGen/sessionFromGen mappers (db/mappers.go) for the
int64/*string -> int/bool/string domain-model narrowing.
Delegated: GetUserByID, GetUserByUsername, UpdateUserStatus,
UpdateUserTOTPSecret, ResetAllUserStatuses, BanUser, UnbanUser,
ListMembers, CreateSession (EvictOldestSessions + InsertSession),
GetSessionByTokenHash, GetSessionWithBanStatus, DeleteSession,
DeleteOtherSessions, DeleteExpiredSessions, TouchSession,
UpdateUserProfile, UpdateUserPassword, ListUserSessions,
DeleteSessionByID (query changed to :execresult so the RowsAffected
ErrNotFound check is preserved). Behavior and public signatures unchanged.

Wire the sqlc-generated dbgen package into db.DB so it stops being dead
code (audit A-2026-07-05) and becomes the real, CI-verified query layer.
db.DB now holds a *dbgen.Queries (initialized in Open via dbgen.New).
Query method bodies delegate to it; sqlc owns the SQL text and parameter
binding (make sqlc-verify), while db keeps its stable public API and
domain model types so no caller in api/admin/ws/service changes. The
migration is incremental — a method either delegates to d.q.* or still
runs raw SQL — so both layers are correct during the transition.
Converted domains (now load-bearing through sqlc):
- blocks: BlockUser, UnblockUser, IsBlocked, IsEitherBlocked,
ListBlockedUsers (added the query to blocks.sql + regenerated).
Empty ListBlockedUsers now returns []int64{} instead of nil, matching
the MemStore backend — a latent inconsistency fixed, not a regression.
- lockouts: UpsertLockout, LoadActiveLockouts, CleanupExpiredLockouts,
DeleteLockout (RFC3339 time formatting/parsing kept in the wrappers).
- roles: GetRoleByID, ListRoles, GetRoleForUser via a shared roleFromGen
mapper (int64 position/is_default -> int/bool). GetUserWithRole stays
raw for now.
Remaining domains stay on raw SQL and are tracked in
docs/plans/sqlc-adoption.md; store/ event+plugin SQL is intentionally
excluded (that layer is removed in D3). Decisions doc + audit closure
updated (A-2026-07-05 -> in progress).
Verified: go build ./...; go test -race ./db ./service ./auth ./ws (api
green non-race, race run matches CI's -timeout 20m); make sqlc-verify and
protocol-verify pass with the regenerated output committed.

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.

Mechanical signature updates for LinkAttachmentsToMessage callsites, plus:
db-level OwnershipGuard test (owned links, foreign never links, legacy
NULL-uploader claimable, nonexistent skipped) and a service-level
SendMessage test proving skip semantics end-to-end including the
already-linked retry path.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The per-attachment GetAttachmentByID pre-check loop was a check-then-link
TOCTOU (the same race pattern this branch fixes elsewhere), an N+1 on the
hot send path, and a hard ErrForbidden for legit retries naming an
already-linked attachment. Ownership now lives in the one UPDATE that
links: `AND message_id IS NULL AND (uploader_id = ? OR uploader_id IS
NULL)` — a foreign attachment can never be claimed, legacy NULL-uploader
rows stay claimable, and skipped rows (foreign/linked/missing) are logged
but never fail the send, so retries can't hard-fail. Subsumes W2-4; the
MemStore (nil,nil) GetAttachmentByID contortion is replaced by a real
map-backed attachment store so the guard is testable (W3-5).
Companion commit updates test callsites and adds ownership coverage.

PostgresStore was 86% stubs behind a build tag nothing enables, pgdbgen
carried hand-added build tags that fought sqlc-verify, and the runtime never
threaded store.Store through the handler boundary. Single-engine reality
shrinks the W1-3 attachment-ownership fix and ends the pgdbgen churn.
Removed: store/postgres.go, db/pgdbgen/, db/queries/postgres/,
migrations/postgres/, the sqlc postgres block, pgx from go.mod, the
startup-refusal branch, and the dead Postgres config surface.

db/queries/sqlite/events.sql was changed (typed CAST for
GetMaxEventSeq) without re-running generation; commit the regenerated
dbgen (interface{} -> int64, no callers depend on the old signature).
Scope sqlc-verify's diff to db/dbgen: regeneration strips the
hand-added //go:build postgres tags in db/pgdbgen, so verifying that
tree can never pass; pgdbgen is scheduled for removal with the
Postgres scaffolding.

Phase B + C review pass: critical security and correctness fixes.
Security
- S1: plugin admin endpoints now require admin.RequireAdminAuth in addition
to AdminIPRestrict. Previously a LAN attacker on the allowed CIDR could
list/enable/disable/uninstall plugins without a session.
- S2: rewrite plugin HTTPDo allowlist with proper net/url parsing. Empty
entries are ignored, suffix matches require a dot boundary, and a custom
Dialer rejects loopback / RFC1918 / link-local addresses to close the
DNS-rebinding TOCTOU window. Redirects re-validated.
- S3 + #9: manifest Name pinned to ^[a-z0-9][a-z0-9_-]{0,63}$, Entrypoint
and UI tab assets validated against absolute / "..", NUL byte, backslash
and non-canonical paths. Asset handler hardened with filepath.Rel check
for symlink and prefix-without-separator escapes.
- S5: pluginBridge postMessage handler ignores the pluginId in the message
body and uses an e.source -> contentWindow lookup instead, defeating
spoofed messages from same-origin scripts.
- S8: HTTPDo body capped at 5 MiB via io.LimitReader, redirects bounded
to 5 hops.
Correctness
- Critical seq alignment: PersistEvent now takes the hub-assigned seq as a
required parameter so the events table row seq always matches the wrapped
payload seq. Hub seeds its in-memory atomic counter from MAX(events.seq)
on startup. Drops in the persister queue no longer mis-align row vs
payload seq.
- #1: live plugin.Registry constructed in main.go BEFORE NewRouter and
threaded through; admin handler is no longer wired with nil.
- #3: EventPersister.Stop is now safe to call without a prior Start by
tracking a started flag — previously deadlocked waiting on done.
Wiring
- NewRouter signature gains *plugin.Registry; two test callers updated.
- admin.RequireAdminAuth exported as a thin wrapper over the existing
package-private adminAuthMiddleware.
- sqlc query templates updated for the new PersistEvent + GetMaxEventSeq
contracts (sqlite + postgres).

Addresses 14 findings from the security audit across all severity levels:
CRITICAL:
- C-1: Add user blocking system (migration, DB queries, REST API, WS DM
send check) to prevent harassment via unconsented DMs
- C-2: Remove server version from unauthenticated /health and /info endpoints
to prevent fingerprinting
HIGH:
- H-1: Remove dangerous-settings feature from tauri-plugin-http
- H-3: Default allowSelfSigned to false in API client (was hardcoded true)
- H-4: Cap invite expiration to 30 days (720 hours)
- H-5: Add 256KB message size limit to LiveKit WS proxy (prevents OOM)
- H-6: Cap concurrent sessions to 25 per user (evicts oldest on overflow)
- H-8: Restrict /diagnostics/connectivity to ADMINISTRATOR role
MEDIUM:
- M-2: Deny access to legacy NULL-uploader unlinked attachments
- M-4: Log warnings on TOTP plaintext decryption fallback paths
- M-8: Remove acceptInvalidCerts from OG preview fetches
- M-10: Expand file upload blocklist (Java .class, OLE2, WASM, .lnk)
- M-12: Add LIMIT to ListInvites (200) and ListMembers (1000)
- M-14: Add CHECK constraint trigger on channels.type (text/voice/dm)

Security audit across all 11 sections (AUTH-001 through DATA-001) found
0 critical, 1 high, 7 medium, 15 low issues. This commit addresses:
- Add json:"-" to User.PasswordHash, User.TOTPSecret, Session.TokenHash
to prevent accidental serialization of sensitive fields (M7)
- Add X-Content-Type-Options: nosniff to file serve responses (M5)
- Apply owner-only guard to backup list endpoint for consistency (M6)
- Persist rate-limit lockouts to SQLite so they survive restarts (M2)
- Normalize DM non-participant responses to 404 to prevent oracle (L3)
- Add explicit per-entry expiry check in partial auth Lookup/Consume (L1)
- Truncate unknown WS message type to 64 chars before echo (L6)
- Rate-limit ping handler to 2/sec per user (L7)
- Replace raw error strings in update handlers with generic messages (L15)
- Update 4 tests to match new 404 behavior for DM non-participant
BUG-107: cleanupAllAudioElements now calls pause() and sets
srcObject = null before removing elements from DOM, ensuring streams
are fully released during reconnection cleanup.
BUG-121: Diagnostics endpoint now has 5 req/min rate limit as
documented, preventing enumeration of internal topology.
BUG-132: DeleteOrphanedAttachments uses DELETE ... RETURNING stored_as
(atomic) instead of separate SELECT then DELETE, eliminating the race
where a file could be deleted after its attachment was linked.
Replace separate UserCount() + CreateUser() with atomic
CreateOwnerIfEmpty() that checks and inserts in a single SQLite
transaction. Concurrent race test validates exactly 1 owner under
20 parallel requests.
Private attachments were accessible without authentication if the UUID
was known. Added AuthMiddleware to the GET /api/v1/files/{id} route,
uploader_id tracking on uploads, and channel-level permission checks
(guild READ_MESSAGES, DM participant, admin bypass) in handleServeFile.
Migration 010 adds uploader_id column to attachments table.
8 new access-control tests covering all authorization paths.
BUG-122: Remove channelID==0 bypass in deliverBroadcast that leaked
all channel-scoped broadcasts to unfocused clients. Clients must now
send channel_focus to receive channel events.
BUG-126: Reject edits and reactions on soft-deleted messages in
handleChatEdit and handleReaction.
BUG-108: Revoke all other sessions when a user changes their password
or enables/disables TOTP 2FA. Adds DeleteOtherSessions DB function.
7 new test cases covering all three fixes.
- BUG-085: ring buffer EventsSince off-by-one — change < to <= so
afterSeq == oldestSeq returns nil (triggers full ready payload)
- BUG-087: GracefulStop not idempotent — wrap body in sync.Once to
prevent double lkProcess.Stop() on concurrent calls
- BUG-090: FTS query truncation at byte boundary — use []rune
truncation to preserve valid UTF-8 for CJK/emoji input
- BUG-091: updater downloadFile double-closes file on Windows —
add closed sentinel to guard defer against explicit Close()
The splitStatements function naively split on every semicolon, breaking
CREATE TRIGGER definitions that contain semicolons inside their
BEGIN...END bodies. Now tracks depth so trigger bodies are kept intact.
Fixes TestWebhook_ParticipantLeft_NoDoubleBroadcast_AfterFreshCleanup
and TestWebhook_ParticipantLeft_OldToken_DoesNotTeardownReplacement.
The migration runner now splits multi-statement SQL files and executes
each statement individually. "duplicate column name" errors are skipped
since the column already exists from a prior partial run. This fixes a
crash on startup when migration 004_voice_optimization.sql re-ran
against a database that already had the columns.
- Add syncutil package with deadlock-detecting mutex (build-tag switchable)
- Add main_test.go TestMain scaffolding across all server packages
- Harden concurrency in ws, admin, auth, and updater packages
- Update CI workflow, go.mod/sum, Cargo.lock, and root changelogen tooling
PATCH /api/v1/users/me — update username/avatar
PUT /api/v1/users/me/password — change password with old pw verification
GET /api/v1/users/me/sessions — list active sessions (single SQL query)
DELETE /api/v1/users/me/sessions/:id — revoke session with ownership check
New files: profile_handler.go, profile_queries.go + tests for both.
All endpoints follow existing writeJSON/errorResponse patterns.
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
