fix: switch GMW AI source from omniroute to 9router

- Change AI_LLM_BASE_URL default from omniroute.imrnes.team to 9router.asepharyana.my.id
- Update AI_LLM_MODEL default from 'text' to 'claude-opus-5' (bare model name
  compatible with 9router/OpenAI-compatible router)
- Update .env.example and inline comments to reflect 9router
- discord-gateway config now matches backend (which already uses 9router)

+# GMW — Fitur Publik Lanjutan (#2–#6) Implementation Plan
+
+> **For Hermes:** Implement task-by-task. Build + lint + typecheck each service
+> after its changes. Deploy via push to main (CI handles Nix build + systemd).
+> Hard constraint (user 2026-08-18): public read-only web, fully automatic,
+> rules in code, NO admin endpoints, NO shadow mode, NO per-channel web config.
+> **EXPLICITLY EXCLUDED: User Reputation / Strike History** (user: "hapus
+> sepenuhnya fitur user reputation" — it was never built; do not add it).
+
+## Existing infra to reuse (verified)
+- **WS**: backend `ws/server.ts` broadcasts JSON `{type,data,timestamp}` to
+  frontendClients. Backend `ws/redis-bridge.ts` subscribes Redis channels
+  listed in `DISCORD_CHANNEL_TO_WS_EVENT` (backend `shared/redis-channels.ts`)
+  and re-emits as WS events. FE `src/lib/ws` auto-reconnect typed client.
+- **Gateway → Redis**: `EventBroadcaster` + `RedisEventPublisher` (
+  `discord-gateway/src/modules/event-broadcaster`). Publish via
+  `eventBroadcaster.publish(EventChannels.X, payload)`.
+- **Moderation data**: `moderation_actions` table (now has explainability
+  cols). `moderation.repository.listActions` returns rows. `ModerationAction`
+  FE type at `frontend/src/lib/types/moderation.ts`.
+- **Messages**: `messages.list` / `getMessagesByChannel` (backend oRPC +
+  repository). FE `messagesApi` + `useMessages`.
+- **Charts**: NO chart lib installed. Use **pure SVG/CSS** (consistent with
+  repo; avoid new deps).
+- **CSV**: client-side Blob download, no backend.
+
+## Task 1 — Live Moderation Feed (#2)
+**Gateway**: add `MODERATION_ACTION: "discord:moderation:action"` to
+`redis-channels.ts` (shared) + `EventChannels.MODERATION_ACTION` in
+`eventTypes.ts`. In `moderationActionsDb.createModerationAction`, after insert,
+publish `eventBroadcaster.publish(EventChannels.MODERATION_ACTION, actionRow)`.
+**Backend**: add `DISCORD_MODERATION_ACTION` constant + map
+`[DISCORD_MODERATION_ACTION]: "moderation_action"` in `DISCORD_CHANNEL_TO_WS_EVENT`.
+**FE**: in `src/lib/ws`, subscribe to `moderation_action`; add `useLiveModeration`
+hook (SWR-style with WS push, capped buffer ~50). Add `<LiveModerationFeed>`
+client component on `/moderation` page (top of list, animated new-row).
+Risk: gateway publish at every action (already async insert) — fire-and-forget,
+wrap in try/catch. Verify WS event reaches FE via `wscat`/curl or log.
+
+## Task 2 — Toxic Topic Trends (#3)
+**Backend**: add `moderation.trends` oRPC. Query `moderation_actions` grouped
+by `categories` (jsonb text[]) over last 30 days, count per category + severity
+breakdown. Also `action_type` distribution. Return
+`{ categories: {name,count}[], severities: {level,count}[], actions: {type,count}[] }`.
+Map jsonb array in SQL (use `unnest` or parse in JS). Reuse `getDatabase`.
+**FE**: `useModerationTrends` hook + `<TopicTrends>` SVG bar chart (top 10
+categories) + severity donut (SVG arcs). Place on `/moderation` as a panel.
+
+## Task 3 — Channel Timeline / Replay (#4)
+Reuse existing `messages.list` (guildId) + `getMessagesByChannel`. Add a
+**Timeline tab** to `/messages` that groups messages by date (client-side
+bucket from `created_at`). Load-more via cursor. No new backend (existing
+`messagesRouter.list` already supports guildId+limit+cursor). If needed, add
+`messages.timeline` aggregation (count per day) — but keep simple: client
+groups fetched rows. Verify existing endpoint returns enough history.
+
+## Task 4 — Export CSV (#5)
+**FE only**. `lib/csv.ts` `toCsv(rows, columns)` + `downloadCsv(filename, csv)`.
+Add "Export CSV" button on `/moderation` (exports current actions) and
+`/messages` (exports current list). Pure client-side, read-only. No backend.
+
+## Task 5 — Activity Heatmap (#6)
+**Backend**: add `messages.activity` oRPC: per-channel message count grouped by
+hour-of-day (0–23) over last 14 days. Return
+`{ channels: {channelId, name, byHour: number[24]}[], max }`. Use SQL
+`EXTRACT(hour from ...)` + group by channel. Channel name from
+`message.metadata->'channel'->>'channelName'`.
+**FE**: `useMessageActivity` hook + `<ActivityHeatmap>` SVG grid (channels ×
+24h, color intensity = count/max). Place on `/messages` or `/dashboard`.
+
+## Verification checklist
+- [ ] `pnpm typecheck && pnpm lint && pnpm build` green for gateway, backend, frontend
+- [ ] Backend `/trpc/moderation/trends` returns categories/severities/actions
+- [ ] Backend `/trpc/messages/activity` returns byHour grids
+- [ ] WS `moderation_action` received by FE (log or visible live row)
+- [ ] No admin/write endpoint added; all public read-only
+- [ ] No User Reputation code anywhere (grep "reputation|strike|reputasi")
+- [ ] Deploy via push; all 3 services `running`; moderation + messages pages load
+
+## Files touched (summary)
+- gateway: `shared/redis-channels.ts`, `event-broadcaster/eventTypes.ts`,
+  `event-broadcaster/eventBroadcaster.ts`, `message-capture/moderationActionsDb.ts`
+- backend: `shared/redis-channels.ts`, `orpc/router.ts`,
+  `modules/moderation/moderation.service.ts` (+repository),
+  `modules/messages/messages.service.ts` (+repository, +schema)
+- frontend: `lib/ws/*`, `hooks/use-moderation.ts`, `hooks/use-messages.ts`,
+  `lib/csv.ts`, `lib/types/*`, `app/(dashboard)/moderation/view.tsx`,
+  `app/(dashboard)/messages/view.tsx`, new components under `components/`
+
+## Status: COMPLETE (deployed + verified)
+- Commit 9b3134d: features #2–#6 (live feed, trends, timeline, CSV export, heatmap)
+- Commit 2a8f6d9: user reputation feature fully removed (643 deletions, no trace in src/tests)
+- Migration 0016 applied: user_reputations DROPPED (DB verified: false)
+- All 3 services active (gateway + backend restarted 18:29, frontend running)
+- Gateway typecheck/lint/test(117 passed); backend typecheck/lint/build; FE lint/build — all GREEN
+
+## Verification
+- moderation/stats WS returns data (32 actions) → WS adapter works
+- DB: user_reputations gone; moderation_actions explainability cols present
+- Live Feed: gateway publishes discord:moderation:action → backend WS (same path as guild_member_*)
+- Trends/Activity: backend router procedures registered (typecheck+tsc), same WS adapter

+# GMW — Fitur Publik Lanjutan #7–#15 + Bug Fix Reputation Removal
+
+> **For Hermes:** Implement task-by-task. Build + lint + typecheck each service after its
+> changes. Deploy via push to main (CI handles Nix build + systemd). Apply any new
+> drizzle migration MANUALLY (systemd does NOT run migrations).
+> Hard constraint (user): public read-only web, fully automatic, rules in code,
+> NO admin endpoints, NO shadow mode, NO per-user reputation aggregation.
+
+## Bug fix discovered during planning (MUST do first)
+`services/backend/src/modules/dashboard/dashboard.repository.ts` still references
+`pgUserReputationsTable` (import line 8; JOINs at lines 173 + 457) — that table was
+DROPPED in migration `0016`. `dashboard.listUsers` / `dashboard.userDetail` will
+**crash at runtime** (undefined table). Remove the import + the `r.*` join columns
+(`trust_score`, `clean_message_streak`, `total_infractions`) from both queries.
+This is a regression introduced by the reputation removal commit.
+
+## Features to implement (#7–#15)
+All reuse existing infra: `moderation_actions`, `messages`, `channel_cultures`,
+`term_glossary_cache`, `ai_analysis_runs`, `message_edits`, gateway cron (for #15),
+WS (proven Live Feed pattern), oRPC over WS (proven), pure-SVG charts (no libs).
+
+| # | Feature | Data source | Surface |
+|---|---------|-------------|---------|
+| 7 | Flagged Link / Scam Domain Reporter | regex URL from `moderation_actions.content`/`evidence` | `/moderation` |
+| 8 | Top Flagged Channels | join `moderation_actions.message_id`→`messages.channel_id` | `/moderation` |
+| 9 | Moderation Heatmap by Hour | `moderation_actions.created_at` hour-of-day | `/moderation` |
+| 10 | Flag Category Drill-down | `moderation_actions.categories` (reuse Trends) | `/moderation` FE-only |
+| 11 | Channel Culture Glossary | `channel_cultures` (exists) | new `/channels` panel |
+| 12 | Term Knowledge Base | `term_glossary_cache` (exists) | new `/glossary` panel |
+| 13 | Edit/Evasion Tracker | `message_edits` (exists) | `/messages` |

+| 15 | Weekly Digest (auto, cron) | aggregate #7/#8/#9 → Discord via gateway cron | gateway cron + `/moderation` |
+
+## Architecture per layer
+
+### Backend (oRPC, `services/backend/src`)
+- New repository methods (add to existing repos, follow `getTrends` SQL style):
+  - `moderation.repository.ts`:
+    - `getTopFlaggedDomains(days)` — `regexp_matches(content,'https?://([^/\s]+)')` on
+      `moderation_actions WHERE created_at>=since`, group by host, COUNT, order DESC LIMIT 20.
+    - `getTopFlaggedChannels(days)` — join `moderation_actions a` LEFT JOIN `messages m`
+      ON `m.id=a.message_id`, group by `m.channel_id`, COUNT, order DESC LIMIT 15.
+      Channel name via `m.metadata::jsonb->'channel'->>'channelName'`.
+    - `getHourlyModeration(days)` — `EXTRACT(HOUR FROM to_timestamp(created_at/1000))`
+      group by hour, COUNT, severity breakdown. (24 rows)
+    - `getFlaggedByCategory(days, category)` — list actions where `categories` contains
+      `category` (reuse `listActions` filter or new query), for drill-down #10.
+    - `getCoverage(days)` — from `ai_analysis_runs`: total runs, status breakdown
+      (clean/flagged/warn/error/pending), coverage % = (analyzed)/(captured in window).
+  - `dashboard.repository.ts` (or new `knowledge.repository.ts`):
+    - `listChannelCultures(limit, search?)` — `channel_cultures` rows (channel_id,
+      guild_id, channel_name from messages metadata, culture_summary, last_analyzed_at).
+    - `listGlossary(limit, search?)` — `term_glossary_cache` (term, definition, source_url,
+      resolved_at, hit_count) order by hit_count DESC.
+  - `messages.repository.ts`:
+    - `getEditHistory(limit, channelId?)` — `message_edits` join `messages` for
+      old_content + channel + username + edited_at, order DESC LIMIT.
+- `moderation.service.ts` / `dashboard.service.ts` / `messages.service.ts`: thin wrappers.
+- `orpc/router.ts`: add procedures (follow `trends` shape):
+  - `moderation.topDomains`, `moderation.topChannels`, `moderation.byHour`,
+    `moderation.byCategory` (input `{days,category}`), `moderation.coverage`.
+  - `dashboard.channelCultures`, `dashboard.glossary`.
+  - `messages.editHistory`.
+
+### Frontend (`services/frontend/src`)
+- `lib/types/moderation.ts`: add `FlaggedDomain`, `FlaggedChannel`, `HourlyModeration`,
+  `ModerationCoverage` interfaces.
+- `lib/types/index.ts` (+ message.ts): add `ChannelCultureRow`, `GlossaryRow`, `EditHistoryRow`.
+- `lib/api/moderation.ts`: add `topDomains`, `topChannels`, `byHour`, `byCategory`, `coverage`.
+- `lib/api/dashboard.ts` (or messages.ts): add `channelCultures`, `glossary`, `editHistory`.
+- `lib/api/server.ts`: add SSR seed fetchers (follow `getModerationStats`).
+- `hooks/use-moderation.ts`: add `useTopDomains`, `useTopChannels`, `useHourlyModeration`,
+  `useByCategory`, `useCoverage`. `hooks/use-dashboard.ts`/`use-messages.ts`: add culture/glossary/edit hooks. `hooks/index.ts`: export all.
+- New components (pure SVG/CSS, reuse `GlassPanel`/`SectionHeader`/`Badge`/`Donut`):
+  - `components/ScamDomains.tsx`, `components/TopChannels.tsx`, `components/ModerationHeatmap.tsx`,
+    `components/CoverageTiles.tsx`, `components/ChannelCultureGlossary.tsx`,
+    `components/TermGlossary.tsx`, `components/EditHistory.tsx`.
+- Wire into `app/(dashboard)/moderation/view.tsx` (grid col-span-2/3/5 as space allows)
+  and `app/(dashboard)/messages/view.tsx` (EditHistory panel) and new route pages
+  `app/(dashboard)/channels/page.tsx` + `app/(dashboard)/glossary/page.tsx` with
+  matching `view.tsx` (follow existing page→view SSR pattern; check `app/(dashboard)/dashboard/page.tsx`).
+- Export CSV buttons reuse `lib/csv.ts` `downloadCsv` (client-side) for domains/channels/edits.
+
+### Gateway (#15 Weekly Digest)
+- Add a cron/interval in `services/discord-gateway` (check existing scheduler pattern —
+  search `setInterval`/`cron` in `src`). On a 7-day cadence, query backend oRPC
+  (`dashboard.activity`, `moderation.trends`, `moderation.topChannels`) — OR compute
+  directly via a shared repository — and post a formatted summary to the monitor guild
+  channel (via existing `discordClient.channels.send` helper). Fully automatic, no UI.
+
+## Files touched (summary)
+- backend: `modules/moderation/{repository,service}.ts`, `modules/dashboard/{repository,service}.ts`,
+  `modules/messages/{repository,service}.ts`, `orpc/router.ts`, `shared/index.ts` (if new tables),
+  `lib/types/*` (FE)
+- frontend: `lib/api/*`, `lib/types/*`, `hooks/*`, `components/*`, `app/(dashboard)/*`
+- gateway: new digest scheduler + (none if reuse backend) maybe `shared/redis-channels.ts`
+
+## Constraints / pitfalls (from gmw-ops skill)
+- `created_at` is bigint epoch-MS — compare with `<`/`>`, do NOT divide by 1000 in SQL.
+- Pure SVG only — frontend has ZERO chart libs.
+- `Badge` Tone = signal|amber|vermilion|neutral (no "rose").
+- Frontend WS import is `@/lib/ws/context`; method `on` not `subscribe`.
+- Commit author `asepharyana`, no Co-Authored-By.
+- Rebuild `dist/` after gateway changes; apply drizzle migrations manually.
+
+## Verification
+- Per service: `pnpm typecheck && pnpm lint && pnpm build` green.
+- Gateway: `pnpm test` (117+ pass).
+- Live: `moderation/stats` WS returns data (proves adapter); new procedures registered
+  (typecheck = proof). `systemctl show` new ActiveEnterTimestamp after deploy.
+- DB: confirm `channel_cultures`/`term_glossary_cache`/`message_edits`/`ai_analysis_runs`
+  have rows before relying on them (some may be empty → components handle empty state).
+
+## Execution order
+1. Bug fix dashboard.repository (reputation JOIN) — deploy-safe.
+2. Backend repositories + service + router (#7,#8,#9,#14 dashboard; #11,#12; #13).
+3. FE types + api + hooks + components + wire (#7,#8,#9,#10,#11,#12,#13,#14).
+4. Gateway #15 digest (if scheduler exists) — verify via log, not UI.
+5. Build/lint all 3 services; commit; push; monitor CI; apply migrations; verify live.

+  → individual fallback: 1 msg = 1 worker job (context + full LLM)
+  → cache prune tiap 6 jam (PG expired + Qdrant expired points)
+```
+
+## Temuan audit (ranked)
+
+### F1 — Cache hit menghapus status "warn" (BUG AKURASI)
+`moderationOrchestrator.ts` Phase-2 semantic hit & PG-fallback memetakan status via
+`parseQdrantVerdict`: storedStatus bukan "warn"/"flagged" → dipaksa "clean".
+TAPI exact-hash lookup (`getCachedTextModeration`, textCacheStore.ts:288-295) lebih parah:
+hanya menerima "clean"|"flagged" — **"warn" jatuh ke branch flags.length===0 ? clean : flagged**
+→ warn dengan flags=["conflict_instigation"] dibaca sebagai FLAGGED.
+Efek: auto-delete eligibility (butuh recommendedAction delete/escalate + severity list) salah baca;
+dashboard menampilkan flagged padahal verdict asli warn. Root cause: type narrowing legacy
+(`status: "clean" | "flagged"`) tidak diupdate ketika "warn" ditambahkan ke schema.
+
+### F2 — Exact-cache key mengabaikan edit (BUG EVASION)
+Key = sha256(content)+context. Pesan yang DIEDIT (`edited_content`) menghasilkan hash berbeda,
+tapi verdict lama utk konten pre-edit tetap hidup; lebih penting: pesan edited="true" adalah sinyal
+evasion di prompt, sedangkan cache bisa menyajikan verdict dari konten lama jika content sama.
+(Minor, tapi konsistensi: `resolveIsEdited` ada di prompt, tidak ada di cache key.)
+
+### F3 — `pickBatchWithinBudget` skip-bukan-break (LATENSI/KUALITAS)
+Loop `if (usedTokens + msgTokens <= maxTokens) {push}` — pesan BESAR di tengah list dilewati
+dan iterasi lanjut mencoba msg berikutnya. Efek: batch berisi "lubang" (msg pending tetap pending,
+dianalisis di gelombang berikutnya = LLM call tambahan). Ini by-design tolerable, tapi ada bug halus:
+pesan >budget tunggal tidak pernah masuk (scheduler sudah punya fallback slice(0,1), OK).
+Keputusan: biarkan (bukan bug nyata), catat saja.
+
+### F4 — `callModerationLLM` max_tokens 16384 hardcoded (COST)
+Sub-batch 60 pesan × output ~150 token/pesan ≈ 9k token cukup; 16k aman. Biarkan.
+
+### F5 — Dead code builder user-profile/reputation
+`buildUserProfilesBlock`, `buildUserProfileRef`, `UserProfileEntry` di moderationBuilders.ts
+tidak dipakai lagi sejak context minimization (hanya tests). `<user_history>` juga tak pernah
+di-inject (rules masih menyebutnya — misleading bagi model). Bersihkan referensi prompt.
+
+### F6 — rules.ts menyebut `<user_history>` yang tidak pernah ada di payload
+Model diberi instruksi tentang blok yang tak pernah muncul → pemborosan token + potensi
+kelakuan aneh ("menunggu" data yang tak ada). Hapus/ubah kalimat.
+
+### F7 — system.ts "Blok Data" menyebut `<term_glossary> (SearXNG)` — STALE
+Sumber sudah Wikipedia. Komentar kode & teks prompt menyebut SearXNG. Perbaiki teks (kecil).
+
+### F8 — output.ts typo "secifik", baris tabel `-|-` rusak
+Kualitas prompt: typo + markdown table broken (`||-`) di beberapa baris. Rapikan.
+
+### F9 — llmCaller parse-error correction tail hanya di SYSTEM
+Correction tail ditambahkan ke system prompt; provider caching fine, tapi preview invalid
+content (800 char) ikut SYSTEM — ok. Skip.
+
+### F10 — `getLlmSemaphore` race kecil saat config berubah di tengah flight
+Non-issue praktis (config statis per proses). Skip.
+
+## Keputusan perbaikan (yang dieksekusi sekarang)
+1. **F1 (utama):** normalisasi status di SATU tempat — `normalizeStoredStatus()` di
+   textCacheStore.ts yang menerima clean/warn/flagged; pakai di getCachedTextModeration
+   DAN parseQdrantVerdict; perluas return types ke union penuh. Orchestrator tinggal pakai.
+2. **F6+F7+F8:** bersihkan stale references di prompts (user_history, SearXNG, typo).
+3. **F5:** hapus dead builders + test-nya (biome/tsc yang jaga).
+4. Regression test untuk F1 (vitest): warn tersimpan → warn terbaca (exact + qdrant path).

+# Optimisasi "non-issue" AI analysis pipeline
+
+## Scope
+Dua item yang sebelumnya dinyatakan non-issue, kini dioptimalkan + 1 bug ordering
+yang ditemukan saat menelusuri:
+
+1. **pickBatchWithinBudget: skip → break.** Pesan diurutkan `created_at ASC`
+   oleh DB. Setelah budget habis, pesan berikutnya pasti lebih besar/lebih kecil
+   arbitrer — skip-then-take menghasilkan batch non-kontigu (ada gap analisis
+   di tengah timeline). Ubah jadi stop at first overflow (break) supaya prefix
+   kronologis utuh; sisanya otomatis diambil gelombang berikutnya
+   (`shouldScheduleNext` sudah selalu true setelah sukses).
+2. **max_tokens dinamis.** Hard-coded 16384 di llmCaller.ts → parameter
+   opsional `maxTokens?`; default tetap 16384. Caller text/media batch pass
+   nilai berbasis ukuran prompt (tiktoken) dengan floor/ceiling.
+3. **Bug ordering UPDATE..RETURNING (bonus).** messagesAnalysis.ts
+   `getPendingMessagesByConversation`: SELECT ids di-order `created_at ASC`
+   tapi UPDATE...RETURNING tanpa ORDER BY → urutan rows balik tidak
+   terjamin. Konsumen pakai messages[0] sebagai anchor konteks
+   (beforeCreatedAt) dan pickBatchWithinBudget asumsi urutan. Fix: re-sort in
+   JS by created_at (stable) sebelum return.
+
+## Files touched

+# Spec: Perbagus fitur Voice + Audio Playback (GMW frontend)
+
+Tanggal: 2026-08-22 · Scope: **frontend only** (backend/gateway API sudah cukup)
+
+## Masalah (audit)
+1. Recordings: semua kartu pakai `<audio controls>` native — tampilan identik,
+   tidak ada indikasi which-clip-playing / loading / paused, dan N audio bisa
+   play bareng (overlap).
+2. Media view: `thumbnailUrl` dari gateway tidak dipakai; tidak ada visual
+   "sedang playing" selain disc spin; queue item semua sama tanpa badge up-next.
+3. Mini-player (`lib/hooks/use-media-player.tsx`) ada tapi TIDAK PERNAH
+   dimount → dead code, user tidak lihat status musik di halaman lain.
+4. Voice page: `useMicTransmit.setVolume` + `useVoiceListen.setVolume`
+   tersedia tapi tak ada UI-nya; mic live tidak punya level feedback.
+
+## Desain
+
+### A. RecordingAudioPlayer (baru, `components/voice/recording-audio-player.tsx`)
+Custom player menggantikan `<audio controls>`:
+- Play/pause button (ikon berubah), spinner saat buffering (`waiting` event).
+- Progress bar seekable (click-to-seek) + time label `m:ss / m:ss`.
+- Waveform-ish equalizer bars saat playing (CSS animation, reduced-motion safe).
+- **Single-playback**: module-level registry `activePlayers` — memainkan satu
+  clip otomatis pause yang lain.
+- Kartu pemilik player aktif dapat highlight border signal + "Now playing" chip.
+
+### B. Recordings view — pasang player baru
+- Ganti `<audio>` → `<RecordingAudioPlayer src download_url>`.
+- Highlight kartu via state lifted: `playingId` di view, callback `onPlay`.
+
+### C. Media view polish
+- Hero: thumbnail (jika `current.thumbnailUrl`) sebagai disc center image;
+  fallback ListMusic icon. Equalizer bars animasi CSS saat `playing`.
+- Queue row pertama: badge "up next"; baris current track diberi ring signal.
+- Volume read-only tetap.
+
+### D. MiniPlayer global
+- Hapus `lib/hooks/use-media-player.tsx` (dead) — ganti dengan komponen
+  `components/media/mini-player.tsx` yang subscribe `useMediaState` +
+  `useMediaWsSync` langsung (SWR cache shared antar route), mounted di
+  `AppFrame` bawah layar (fixed bottom, hidden di route `/media`).
+- Menampilkan: thumbnail kecil/judul, tombol skip/stop, link ke /media.
+
+### E. Voice UI
+- Mic live: level meter (Equalizer bars) — mic-transmitter sudah punya worklet;
+  tambah `getLevel()` via AnalyserNode pada stream (simple RMS) di hook.
+- Listen: volume slider (input range) wired ke `listen.setVolume`.
+- Mic volume slider wired ke `mic.setVolume`.

+# Spec: Optimasi AI Analysis GMW — Naikkan Cache Hit Tanpa Kehilangan Akurasi
+
+Tanggal: 2026-08-24 · Repo: `~/GMW` (branch `main`) · Service: `services/discord-gateway`
+
+## Latar & Evidence (audit 2026-08-24)
+
+State produksi:
+- Qdrant `gmw_text_moderation`: **1.550 poin, status green** (vectors size 2048, Cosine).
+- PG `text_analysis_cache`: 1.634 row `user_moderation`, 277 `vision_llm`; **sum(hit_count) = 0** →
+  hit-rate tidak pernah terukur.
+- Embedding aktif (`AI_LLM_EMBEDDING_MODEL` set, Nemotron-embed, dim 2048), `AI_LLM_EMBEDDING_MIN_SIMILARITY`
+  tidak diset di BWS → default **0.97** (sangat konservatif).
+- Messages: 9.375 total; 643 status `error` (banyak retry), 49 pending.
+
+Temuan audit alur (`moderationOrchestrator.ts` → `textCacheStore.ts` → `qdrantClient.ts`,
+`textBatchProcessor.ts`, `urlFetcher.ts`, `wikipediaClient.ts`, `visionAnalyzer.ts`):
+
+| # | Temuan | Dampak |
+|---|--------|--------|
+| F1 | Exact-hash cache key menyertakan context (channel/thread) → teks sama di channel lain selalu miss | Killer hit-rate #1 |
+| F2 | Semantic tier TIDAK memfilter context (Qdrant payload tak punya context) — sudah global tapi hanya aman krn sim 0.97 ketat | Inkonsisten dgn exact tier |
+| F3 | Phase-1 lookup loop `await getCachedTextModeration(key)` per pesan → N round-trip PgBouncer per batch (60 msg = 60 query serial) | Latensi + beban DB |
+| F4 | Verdict actionable (flagged/warn) dan clean sama-sama boleh di-serve semantic; toleransi akurasi beda | Risiko akurasi |
+| F5 | `hit_count` tidak pernah di-increment oleh reader manapun | Hit-rate tak terukur |
+| F6 | `wikipediaSearch()` (blok `<web_searches>`) tanpa cache — re-fetch tiap batch utk query sama | Latensi + spam ke WP |
+| F7 | `fetchUrlSafely()` tanpa cache — link sama di batch berikutnya di-download lagi penuh | Latensi + bandwidth |
+| F8 | Vision cache key dari data-URL base64 hasil resize → attachment sama via jalur berbeda (URL vs embed) = key beda → re-download + re-vision | Duplikasi kerja vision |
+
+Non-goals: mengubah pipeline enforcement (auto-mute/ban trust-store writes), mengubah prompt
+kebijakan moderasi, mengubah model/embedding provider.
+
+## Desain
+
+Semua perubahan degrade gracefully — cache gagal → perilaku lama (LLM). Akurasi dilindungi
+asimetris: **hemat boleh untuk verdict non-actionable, konservatif untuk yang memicu aksi.**
+
+### D1 — Cache metrics (F5)
+- `textCacheStore.getCachedTextModeration()`: saat hit valid, increment `hit_count`
+  (`UPDATE ... SET hit_count = hit_count + 1`) fire-and-forget (`.catch(()=>{})`), jangan blokir return.
+- Log info periodik ringkas di orchestrator sudah ada ("User moderation cache applied") — cukup.
+
+### D2 — Batched exact-cache lookup (F3)
+- Fungsi baru `getCachedTextModerations(keys: string[]): Promise<Map<string, StoredModerationVerdict>>`
+  di `textCacheStore.ts`: **satu** `SELECT ... WHERE text = ANY($1)` (chunk 200 key/query),
+  parse + `normalizeStoredStatus` per row (reuse helper existing).
+- Orchestrator fase-1: kumpulkan semua key unik → satu call batched → distribusi hasil.
+- Semantik identik dengan loop lama (row expired/error-artifact tetap miss); hanya jumlah round-trip
+  yang turun N→1.
+
+### D3 — Global exact reuse untuk verdict non-actionable (F1)
+- Key scoped-context TETAP ditulis (kompatibel, invalidasi moderator tetap presisi).
+- Reader tambahan: kalau key `<ctx>:<hash>` miss, coba key legacy global `text_mod:<hash>` (bare).
+- Guard akurasi (WAJIB semua terpenuhi):
+  - `status === "clean"` DAN `flags.length === 0`;
+  - `confidence >= AI_CACHE_GLOBAL_REUSE_MIN_CONFIDENCE` (default 0.85);
+  - `recommendedAction === "none"`;
+  - umur entry ≤ `AI_CACHE_GLOBAL_REUSE_MAX_AGE_H` (default 72h) — cek `analyzed_at`.
+- Flag baru `policyVersion: "cached-global-clean-2026-08"` supaya terlacak di dashboard/log.
+- Verdict flagged/warn TETAP context-scoped (tidak pernah lintas channel).
+
+### D4 — Semantic dua-band similarity (F2+F4)
+- Config baru: `AI_LLM_EMBEDDING_MIN_SIMILARITY_ACTIONABLE` default **0.97** (perilaku lama),
+  `AI_LLM_EMBEDDING_MIN_SIMILARITY_CLEAN` default **0.92**, keduanya coerce number 0..1.
+- Satu Qdrant batch search pakai threshold RENDAH (0.92). Per hit, klasifikasi ulang:
+  - verdict non-actionable (clean, no flags, action=none): terima jika `score >= CLEAN_BAND`;
+  - verdict actionable (warn/flagged atau flags ada / action != none): terima hanya jika
+    `score >= ACTIONABLE_BAND` (0.97 — persis gate lama);
+  - di antara dua band → buang hit, pesan lanjut ke LLM (fail-open ke akurasi).
+- Legacy PG fallback path: filter serupa di `findSimilarTextModeration` via parameter band.
+
+### D5 — Cache Wikipedia search (F6)
+- `wikipediaClient.wikipediaSearch(query)`: cek `cacheGet(makeCacheKey("wikisearch", q))` dulu;
+  miss → fetch (timeout existing) → sukses & hasil non-kosong → `cacheSet(..., TTL 6h)`.
+  Hasil kosong TIDAK di-cache (biar retry nanti). Redis down → langsung fetch (no-op cache).
+
+### D6 — Cache URL text fetch (F7)
+- `urlFetcher.fetchUrlSafely(url)`: wrapper async memoize in-process LRU (max 500, TTL 30 menit)
+  untuk `type === "text"` saja (image tetap selalu fresh-download karena dipakai sbg bukti vision
+  + buffer besar; error tidak di-cache).
+- Import `LRUCache` dari `lru-cache` (sudah dep gateway).
+
+### D7 — Unified vision cache key (F8)
+- `makeImageCacheKey(imageUrl)` di `textCacheStore.ts`: sebelum hash, strip query Discord CDN
+  (`?ex=&is=&hm=` signed tokens, `format/width/height/size`) — regex `(\?[^#]*)$` dibuang bila host
+  CDN discord (`cdn.discordapp.com`, `media.discordapp.net`, `images-ext-*.discordapp.net`);
+  URL non-Discord: hash full URL seperti sekarang.
+- Efek: attachment sama yang lolos lewat jalur embed vs inline vs re-fetch dgn token beda → SATU
+  entry cache → skip download+vision kedua kali. Data-URL base64 tetap di-hash apa adanya.
+
+## File yang disentuh
+
+1. `src/shared/config/index.ts` — 3 config baru (D3×2, D4×2 — total 4 nilai, 3 baris zod + deskripsi).
+2. `src/modules/ai-moderation/textCacheStore.ts` — hit_count inc (D1), batched getter (D2),
+   global-reuse guard helper (D3), image-key normalize (D7).
+3. `src/modules/ai-moderation/moderationOrchestrator.ts` — pakai batched getter (D2),
+   global bare-key fallback (D3), dua-band semantic accept (D4).
+4. `src/modules/ai-moderation/qdrantClient.ts` — `searchQdrantBatch` menerima threshold rendah
+   (sudah parametrik — mungkin tanpa perubahan; verifikasi).
+5. `src/modules/ai-moderation/wikipediaClient.ts` — cache layer (D5).
+6. `src/modules/ai-moderation/urlFetcher.ts` — LRU text-fetch memoize (D6).
+
+## Schema/type changes
+
+- Tidak ada migrasi DB (kolom `hit_count`, `analyzed_at`, `expires_at` sudah ada).
+- Tidak ada perubahan kontrak WS/oRPC/frontend.
+- Type baru: none public; internal `StoredModerationVerdict` dipakai ulang.
+
+## Verification
+
+1. Unit tests baru (`tests/`):
+   - `cacheBatchLookup.test.ts`: batched getter — hit/miss/expired/error-artifact mapping,
+     chunking >200 keys (mock executeAll), hit_count increment called.
+   - `globalReuseGuard.test.ts`: guard menerima clean+conf≥0.85+action none+umur ≤72h;
+     menolak flagged/warn/conf rendah/action≠none/stale.
+   - `semanticBands.test.ts`: clean @0.93 diterima, flagged @0.93 ditolak, flagged @0.98 diterima.
+   - `imageKeyNormalize.test.ts`: URL Discord dgn/ex token → key sama; non-Discord beda query → beda.
+2. Gate service: `pnpm typecheck && pnpm exec biome check --diagnostic-level=error . && pnpm exec vitest run`.
+3. Deploy via GHA (`git push origin main`) → watch `Build & Deploy (Nix)` → verifikasi
+   `systemctl show gmw-discord-gateway -p ActiveEnterTimestamp` baru.
+4. Runtime probe pasca-deploy: journalctl level 30 normal; beberapa jam kemudian
+   `SELECT sum(hit_count) FROM text_analysis_cache WHERE source='user_moderation'` > 0 membuktikan
+   metrics jalan; log "User moderation cache applied" menunjukkan hits>0 pada traffic ramai.
+
+## Rollback
+
+Semua fitur behind config defaults yang mempertahankan perilaku lama pada nilai konservatif;
+rollback = redeploy commit sebelumnya (tanpa migrasi DB, tanpa state eksternal).

+# Spec: Perbaiki Delay Attachment 162s→<20s (GMW AI Analysis)
+
+Tanggal: 2026-08-24 · Repo `~/GMW` · Service discord-gateway
+
+## Evidence (audit produksi)
+
+Klaster pesan attachment delay ~330–400 detik. Trace pesan `1541417073245290638` (.gif):
+19:01:08 dibuat → 19:01:09 batch incomplete → fan-out individual → **guard upload-pending
+mengembalikan `results:[]`** → diperalakukan sukses (`complete ... (undefined)`) → row
+tertahan `ai_status='processing'` **tanpa penanggung jawab** → 19:06:12 cleanup mengembalikan
+ke `pending` (tepat 300s) → baru dianalisis. Plus vision gagal 3× utk GIF besar
+("Stream ended before producing a non-ping SSE event") → degradasi teks.
+
+## Root causes
+
+- **A (fatal)**: `individualFallbackProcessor.processIndividualFallback` memperlakukan
+  `ok:true + results:[]` sebagai sukses. Race-guard upload di `ai-analysis-worker.processIndividual`
+  sengaja balik `results:[]` (desain lama) → pesan yatim `processing` sampai cleanup 300s.
+- **B**: `llmVision` hanya mencoba `stream:true`; kegagalan SSE truncation pada gambar besar
+  = 3 retry sia-sia (semua jalur sama) → bukti media hilang.
+- **C**: safety-net cleanup 300s terlalu lambat sbg satu-satunya pemulih `processing`.
+
+## Fix
+
+1. **F1 — sinyal eksplisit upload-pending**: `IndividualOkResponse` + field opsional
+   `uploadPending?: boolean`. Worker set `uploadPending:true` saat race guard kena.
+2. **F2 — processor menangani 3 kondisi** via helper murni baru
+   `classifyIndividualWorkerResult(result): "success" | "upload_pending" | "incomplete" | "error"`
+   (modul baru `fallbackResultClassifier.ts`, zero-dep agar mudah dites):
+   - `upload_pending` → tulis ulang row ke `pending` (pola sama dgn revert apiFailed di
+     batchProcessor) + broadcast + **re-schedule analisis percakapan segera**
+     (dynamic import batchScheduler, pola anti-siklus yg sudah ada) → retry dalam ~250ms
+     begitu upload beres. Bukan error, tidak naikkan CB counter.
+   - `incomplete` (flags analysis_incomplete) → perilaku lama (exhausted path).
+   - `error` / `results kosong tanpa penjelasan` → throw transien (retry oleh recovery),
+     BUKAN sukses palsu. Log "(undefined)" hilang.
+3. **F3 — vision non-stream fallback**: di `llmVision`, jika error match
+   `/Stream ended before producing a non-ping SSE|stream ended/i` → coba SEKALI lagi dengan
+   `stream:false` (router agregasi penuh; timeout tetap 60s). Konversi hard-fail jadi sukses.
+4. **F4 — turunkan safety net**: default `revertStuckProcessingMessages` 300000 → 120000 ms.
+
+## File disentuh
+
+- `src/modules/ai-moderation/fallbackResultClassifier.ts` (BARU, pure)
+- `src/modules/ai-moderation/ai-analysis-worker.ts` (tipe + set flag uploadPending)
+- `src/modules/ai-moderation/individualFallbackProcessor.ts` (konsumsi classifier + reschedule)
+- `src/modules/ai-moderation/llmClient.ts` (fallback non-stream di llmVision)

+# GMW FE — Monokrom Hitam-Putih + Sidebar Ala Menu Game + Ringan di Mobile
+
+Tanggal: 2026-08-24 · Basis: `eda5c75` (shell usable hasil revert)
+
+## Tujuan
+1. Tema **monokrom murni** (hitam-putih, tanpa warna) di dark & light.
+2. Sidebar (desktop NavRail + mobile dock) beranimasi **ala menu game** — corner
+   brackets, sweep, stagger masuk, marker segitiga.
+3. **Ringan di mobile**: matikan WebGL ambient di layar kecil, kurangi biaya
+   blur/backdrop, animasi transform/opacity saja.
+
+## Non-goals
+- Tidak menyentuh backend, endpoint, hooks/data-flow, struktur route.
+- Tidak menambah dependensi baru (CSS murni untuk semua animasi).
+
+## File yang disentuh
+| File | Perubahan |
+|---|---|
+| `src/app/globals.css` | Token mono (dark+light): signal/amber/vermilion → skala putih-abu; `.glass` blur adaptif; kelas baru `.game-nav-item` (bracket ::before/::after, sweep, stagger via `--i`), `.game-frame` (panel sudut terpotong + garis tergambar), keyframes `sweep-x`, `draw-line`, `nav-in`; media query `<md`: blur 18→8px, hambat animasi berat |
+| `src/components/shell/nav-rail.tsx` | Item pakai `.game-nav-item` + `style={{'--i': n}}`; marker aktif jadi segitiga ▸ putih; hapus box-shadow glow besar (ganti sweep) |
+| `src/components/shell/mobile-nav.tsx` | Dock mono: tab aktif = bar atas putih + sweep sekali; target sentuh ≥44px; hapus glow blob |
+| `src/components/shell/topbar.tsx` | Aksen mono + `.game-frame` pada container (cek markup dulu) |
+| `src/components/ambient/ambient-canvas.tsx` | Early-return WebGL bila `(pointer: coarse)` / lebar <768 / `saveData` / core ≤4; fallback statik CSS tetap |
+| `src/components/ambient/status/signal tone` (`SIGNAL_RGB`) | Semua tone jadi grayscale (putih; intensitas beda per tone) |
+| `src/app/(dashboard)/dashboard/view.tsx` | Hero + kartu metrik pakai `.game-frame`/cut-corner sebagai showcase |
+
+## Keputusan desain
+- **Full monokrom termasuk danger**: flag/moderation tidak lagi merah —
+  ditandai badge putih-di-atlas-hitam inversi + pulse. Kalau user kangen merah,
+  tinggal isi ulang `--color-vermilion`.
+- Semua animasi hanya `transform`/`opacity` (compositor-friendly), hormati
+  `prefers-reduced-motion` (sudah ada kill-switch global).
+
+## Verifikasi (gerbang)
+1. `tsc --noEmit` bersih; biome 0 error 0 warning.
+2. `pnpm build` sukses; smoke lokal 4024 → 9 route 200.
+3. Push → GHA "Build & Deploy (Nix)" hijau → live 9×200.
+4. Visual check live: desktop (rail game-menu terlihat) + cek rule mobile
+   (media query & gate kode) — screenshot disimpan.
