Subject: [PATCH 01/11] security: escape user content in triage prompt
 delimiters (#164)

Add escapePromptDelimiters() to HTML-encode < and > in user-supplied
message content before it is inserted between XML-style section tags
in the LLM prompt.

Without escaping, a crafted message containing the literal text
`</messages-to-evaluate>` could break out of the user-content section
and inject attacker-controlled instructions into the prompt structure.

Changes:
- Add escapePromptDelimiters(text) utility exported from triage-prompt.js
- Apply escape to m.content and m.replyTo.content in buildConversationText()
- Add 13 new tests covering the escape function and injection scenarios

Closes #164

- Add & → &amp; escape first in escapePromptDelimiters() to prevent
  HTML entity bypass attacks (e.g. &lt;/messages-to-evaluate&gt;)
- Also escape m.author and m.replyTo.author since Discord display
  names are user-controlled and can contain < / > characters

Addresses review feedback on PR #204.

Subject: [PATCH 05/11] perf: SQL-based conversation pagination + missing DB
 indexes (#221)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes three performance bottlenecks identified in code review of
recently merged features (PR #121 conversations viewer, PR #190 AI feedback).

## Changes

### migrations/004_performance_indexes.cjs (new)
Four new indexes targeting hot query paths:

- idx_ai_feedback_guild_created (guild_id, created_at DESC)
  getFeedbackTrend() and getRecentFeedback() filtered by guild_id
  AND created_at but only had a single-column guild_id index, forcing
  a full guild scan + sort on every trend/recent call.

- idx_conversations_content_trgm (GIN, pg_trgm)
  content ILIKE '%...%' search was a sequential scan. GIN/trgm index
  reduces this from O(n) to O(log n * trigram matches).
  Requires pg_trgm extension (added idempotently).

- idx_conversations_guild_created (guild_id, created_at DESC)
  Default 30-day listing query filters guild_id + created_at. The
  existing 3-column (guild_id, channel_id, created_at) composite is
  suboptimal when channel_id is not in the predicate.

- idx_flagged_messages_guild_message (guild_id, message_id)
  Conversation detail + flag endpoints query flagged_messages by
  guild_id AND message_id = ANY(...). Existing index only covers
  (guild_id, status).

### src/api/routes/conversations.js
**GET / — Replace in-memory pagination with SQL CTE grouping**

Before: fetched up to 10,000 message rows into Node memory, grouped
them in JavaScript (O(n) time + memory), then sliced for pagination.
Every page request loaded the full 10k row dataset.

After: single SQL query using window functions (LAG + SUM OVER) to
identify conversation boundaries and aggregate summaries directly.
COUNT(*) OVER() provides total count without a second query.
Pagination happens at the DB with LIMIT/OFFSET on summary rows.
Memory overhead is now proportional to page size (default 25), not
total conversation volume.

Removed now-unused buildConversationSummary() helper (logic inlined
into the SQL-side aggregation).

**POST /:conversationId/flag — Parallel verification queries**

Before: msgCheck and anchorCheck ran sequentially (~2× RTT).
After: both run in parallel via Promise.all (1× RTT for verification).

### tests/api/routes/conversations.test.js
Updated 'should return paginated conversations' test to mock the new
SQL CTE response shape (pre-aggregated summary rows) instead of raw
message rows. All 41 conversation tests pass.

Subject: [PATCH 06/11] feat: channel-level quiet mode via bot mention (#173)
 (#213)

* feat: quiet mode per-channel via bot mention (#173)

- Add quietMode.js module with Redis+memory storage
- Parse duration from natural language (30m, 1 hour, etc.)
- Permission gated via config.quietMode.allowedRoles
- Commands: quiet, unquiet, status
- Suppress AI responses during quiet mode in events.js
- Add quietMode section to config.json (disabled by default)
- Add quietMode to configAllowlist.js for dashboard editing

* test: add quiet mode tests (41 tests, all passing)

* style: fix biome formatting in quietMode.js, events.js, and test

* fix(web): fix ai-feedback-stats TypeScript and formatting errors

* fix: gate quiet mode checks on enabled flag, validate TTL, honor maxDurationMinutes config

- events.js: Wrap isQuietMode() calls in guildConfig.quietMode?.enabled check
  to avoid unnecessary Redis lookups and prevent stale records from suppressing
  AI responses when the feature is disabled (PRRT_kwDORICdSM5xdbmp, PRRT_kwDORICdSM5xdbmx)

- quietMode.js: Add TTL validation in setQuiet() to guard against 0, negative,
  or NaN values that would error in Redis (PRRT_kwDORICdSM5xdbm3)

- quietMode.js: Update parseDurationFromContent() to accept config parameter
  and honor guildConfig.quietMode.maxDurationMinutes. Also clamp defaultSeconds
  to the effective max (PRRT_kwDORICdSM5xdbm_)

- configValidation.js: Add quietMode schema entry with enabled, maxDurationMinutes,
  and allowedRoles properties (PRRT_kwDORICdSM5xdbnH)

* style: fix biome formatting in quietMode.js and ai-feedback-stats.tsx

* feat: audit log improvements — CSV/JSON export, real-time WebSocket stream

- Add GET /:id/audit-log/export endpoint (CSV and JSON, up to 10k rows)
- Add /ws/audit-log WebSocket server for real-time audit entry broadcast
- Refactor buildFilters() shared helper to eliminate duplication
- Hook broadcastAuditEntry() into insertAuditEntry (RETURNING id+created_at)
- Wire setupAuditStream/stopAuditStream into startServer/stopServer lifecycle
- Add escapeCsvValue/rowsToCsv helpers with full test coverage
- 30 route tests + 17 WebSocket stream tests, all green

Closes #136

* fix: PR #215 review feedback - audit stream fixes

- ws.ping() crash: guard with readyState check + try/catch to avoid
  crashing heartbeat interval when socket not OPEN
- stopAuditStream race: make setupAuditStream async and await
  stopAuditStream() to prevent concurrent WebSocketServer creation
- Query param array coercion: add typeof === 'string' checks for
  startDate/endDate to handle Express string|string[]|undefined
- CSV CRLF quoting: add \r to RFC 4180 special-char check for proper
  Windows line ending handling
- Test timeouts: make AUTH_TIMEOUT_MS configurable via
  AUDIT_STREAM_AUTH_TIMEOUT_MS env var, use 100ms in tests

* feat: add voice_sessions migration (#135)

* feat: add voice tracking module — join/leave/move/flush/leaderboard (#135)

* feat: wire voiceStateUpdate handler into event registration (#135)

* feat: add /voice command — leaderboard, stats, export subcommands (#135)

* feat: add voice config defaults to config.json (#135)

* feat: wire voice flush start/stop into bot lifecycle (#135)

* feat: add voice to config API allowlist (#135)

* fix: SQL UPDATE subquery for closeSession, fix import order (#135)

* fix(voice): resolve race conditions and missing config schema

- Fix openSession: update in-memory state only AFTER DB INSERT succeeds
- Fix closeSession: delete from in-memory state only AFTER DB UPDATE succeeds
- Fix: allow closeSession on leave/move even when feature is disabled
- Fix migration: add UNIQUE constraint to partial index to prevent duplicates
- Fix: move 'Voice join' log to after openSession succeeds
- Add voice config to CONFIG_SCHEMA for validation

Subject: [PATCH 09/11] feat(dashboard): auto-save config with 500ms debounce
 (#199)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* feat(dashboard): replace manual save with auto-save (500ms debounce)

- Remove 'Save Changes' button; saving now fires automatically 500ms
  after the last config change (no changes → no network call)
- Add saveStatus state ('idle' | 'saving' | 'saved' | 'error') with
  AutoSaveStatus component showing spinner, check, or error+retry
- Add isLoadingConfigRef guard so the initial fetchConfig load never
  triggers a spurious PATCH
- Ctrl+S still works: clears debounce timer and saves immediately
- Keep 'beforeunload' warning for validation errors that block save
- Replace yellow unsaved-changes banner with a destructive validation
  error banner (only shown when save is actually blocked)
- Error state shows 'Save failed' + 'Retry' button for user recovery

Closes #189

* test(dashboard): add auto-save tests for ConfigEditor

- No PATCH on initial config load
- Validation error banner suppresses auto-save
- 'Saving...' spinner visible while PATCH in-flight
- 'Save failed' + Retry button on PATCH error

* fix(dashboard): prevent fetchConfig from overwriting saveStatus after successful save

Add skipSaveStatusReset parameter to fetchConfig so that post-save reloads
preserve the 'saved' status indicator instead of immediately resetting to 'idle'.

* test(dashboard): use fake timers, restore vi.stubGlobal, fix assertions, add idle/saved coverage

- Replace real setTimeout delays with vi.useFakeTimers() + vi.advanceTimersByTimeAsync()
  for deterministic, fast debounce tests
- Add afterEach cleanup: vi.unstubAllGlobals() + vi.useRealTimers()
- Replace toBeTruthy() with toBeInTheDocument() for Testing Library queries
- Add idle state test (no status indicator shown after load)
- Add saved state test (shows 'Saved' after successful save)
- Update file-level comment to list all four states

Subject: [PATCH 10/11] feat: Reaction role menus (#162) (#205)

* feat: reaction role menus - core module, command, event hooks, migration

Implements issue #162: reaction role menus.

- Add migration 004 creating reaction_role_menus and reaction_role_entries tables
- Add src/modules/reactionRoles.js with DB helpers, embed builder, event handlers
- Add src/commands/reactionrole.js with /reactionrole create|add|remove|delete|list
- Wire handleReactionRoleAdd/Remove into registerReactionHandlers in events.js

Roles are granted on reaction add and revoked on reaction remove.
All mappings persist in PostgreSQL across bot restarts.

* test: reaction role menus - 40 tests covering module and command

- tests/modules/reactionRoles.test.js: resolveEmojiString, buildReactionRoleEmbed,
  all DB helpers, handleReactionRoleAdd, handleReactionRoleRemove
- tests/commands/reactionrole.test.js: all 5 subcommands (create, add, remove,
  delete, list) including error paths and guild ownership checks
- Fix biome lint: import sort order + unused import removal

* fix: remove unused import in reactionrole command

Subject: [PATCH 11/11] fix(security): validate GitHub owner/repo format before
 gh CLI call (#198)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(security): validate GitHub owner/repo format before gh CLI call

Prevents API path traversal by validating owner/repo segments against
a strict allowlist regex before interpolating them into the gh CLI
invocation.

Adds:
- VALID_GH_NAME regex (/^[a-zA-Z0-9._-]+$/)
- isValidGhRepo() helper (exported for testing)
- Guard in fetchRepoEvents() — returns [] and warns on invalid input
- Strengthened guard in pollGuildFeed() split logic

Fixes #160

* test(security): add validation tests for GitHub owner/repo format

Covers isValidGhRepo(), VALID_GH_NAME regex, and fetchRepoEvents()
validation guard introduced in fix for #160.

19 new tests verify:
- Valid alphanumeric/dot/hyphen/underscore names pass
- Path traversal (../../etc/passwd) is rejected at both entry points
- Slashes, empty strings, non-strings, spaces all rejected
- Shell metacharacters (; && $()) blocked
- gh CLI is NOT invoked when validation fails
- warn() fires with the invalid values (observable audit trail)
- Valid owner/repo still reach gh CLI unchanged

* fix(security): reject pure-dot owner/repo names to prevent path traversal

* test(githubFeed): add tests for pure-dot path traversal bypass
