+# GMW Frontend — Greenfield Rebuild (Visual-System Overhaul + Custom UI + Motion/3D)
+
+> **For Hermes:** Execute with `subagent-driven-development` (one fresh subagent per task, two-stage review). Each task is 1–3 min, atomic, independently verifiable, committed after each. Reuse `src/lib/api/*`, `src/lib/ws/*`, `src/lib/types/*`, hooks verbatim. Never invent endpoints.
+
+**Goal:** Rebuild the GMW Discord-automod dashboard frontend from scratch — drop shadcn/ui + glass/teal/purple aesthetic entirely, replace with a custom, distinctive design system where every page has its own visual metaphor (no uniform bordered-card grid), and push the presentation layer with **Framer Motion (`motion`) choreography + signature Three.js scenes**. Re-integrate to the EXISTING backend API + WebSocket contract (do NOT touch the backend).
+
+**Architecture:** Next.js 16 App Router (SSR) + React 19 + TS strict + Tailwind v4. Keep the *plumbing* (data contract), rebuild the *skin + primitives + motion*. Each route = one self-contained `page.tsx` (server fetch + client view in the same file via a `"use client"` sibling export). Custom SVG charts (no recharts). Custom micro-primitives (no shadcn/base-ui). New token system in `globals.css`. **Motion:** `motion/react` app-wide for page transitions, spring micro-interactions, layout animation. **3D:** raw `three` (no react-three-fiber — leaner) in exactly TWO signature scenes, lazy-loaded client-only with graceful fallback. Deployed unchanged via existing flake + `gmw-proxy` nginx (`:4009` → Next `:4017`).
+
+**Tech Stack:** next@16, react@19, tailwindcss@4 (`@import "tailwindcss"`), `next/font/google` (Bricolage Grotesque + Inter + JetBrains Mono), `swr` (data revalidation), `lucide-react` (icons only), `motion` (Framer Motion successor — `motion/react`), `three` + `@types/three` (signature scenes only), `clsx` + `tailwind-merge`. **Removed:** `@shadcn/react`, `@base-ui/react`, `recharts`, `shadcn` CLI, `cmdk`, `sonner`, `react-day-picker`, `embla-carousel-react`, `react-resizable-panels`, `input-otp`, all 50 `components/ui/*`.
+
+---
+
+## 0. Design System (the creative core — read before coding)
+
+**Persona:** Controlled UX Designer + a tactical "ops console" voice. Material honesty: hierarchy via **scale/weight/tonal blocks**, NOT borders/shadows. Per `frontend-design` skill principle — spend the boldness in ONE signature place per page, keep the rest disciplined. Motion is choreography, not confetti: **one orchestrated moment per page**, everything else quiet.
+
+### Palette (warm, signal-driven — NO teal/cyan/purple/blue gradients)
+Light mode (`:root`):
+```
+--canvas:      oklch(0.96 0.012 80)    /* warm off-white, not cream */
+--surface:     oklch(0.92 0.014 80)    /* tonal block, replaces bordered card */
+--surface-2:   oklch(0.88 0.016 80)
+--ink:         oklch(0.22 0.02 70)     /* primary text */
+--ink-soft:    oklch(0.46 0.02 70)     /* secondary text */
+--hairline:    oklch(0.22 0.02 70 / 0.10)  /* structural rules ONLY, sparse */
+--signal:      oklch(0.78 0.17 125)    /* lime — OK / live / primary accent */
+--signal-ink:  oklch(0.20 0.03 70)     /* text ON signal */
+--amber:       oklch(0.80 0.15 70)     /* WARN */
+--vermilion:   oklch(0.62 0.21 25)     /* FLAGGED / destructive */
+--ring:        var(--signal)
+```
+Dark mode (`.dark`, default theme per `next-themes`):
+```
+--canvas:      oklch(0.13 0.015 70)    /* warm charcoal, not blue-black */
+--surface:     oklch(0.18 0.02 70)
+--surface-2:   oklch(0.23 0.022 70)
+--ink:         oklch(0.93 0.01 75)
+--ink-soft:    oklch(0.62 0.02 75)
+--hairline:    oklch(1 0 0 / 0.09)
+--signal:      oklch(0.88 0.18 125)
+--signal-ink:  oklch(0.18 0.03 70)
+--amber:       oklch(0.85 0.15 70)
+--vermilion:   oklch(0.68 0.21 25)
+```
+Three semantic signals reused everywhere: **lime = OK/live, amber = warn, vermilion = flag/danger**. This kills the purple-accent + teal-primary monotony.
+
+### Typography (3 roles, deliberate pairing — not "Inter everywhere")
+- **Display:** `Bricolage Grotesque` (700–800) — characterful grotesque for headers/big numbers.
+- **Body/UI:** `Inter` (400–600).
+- **Data/label:** `JetBrains Mono` (500/700) — all stats, timestamps, channel IDs, metrics.
+Load all three via `next/font/google` with CSS variables (keep current `--font-inter`/`--font-jetbrains-mono` names + add `--font-display`).
+
+### Layout & signature
+- **No `card` with border.** Use tonal `--surface` blocks with generous radius (`--r: 14px`) and internal padding; separate blocks with whitespace + sparse hairlines only where structurally meaningful.
+- **Signature element = "scan-tick":** a 1px animated pulse line (CSS keyframe `scan`) that marks every live/section header — NOT a card outline. Global canvas carries a faint warm dot-grid texture (low opacity) instead of the current bluish dotted radial-gradient.
+- **Nav = left "spine":** vertical rail of icon nodes joined by a hairline; active node gets a `--signal` dot + label reveal. Collapses to a bottom tab-bar < 768px (CSS only, no JS sidebar primitive).
+- **Header = "status bar":** connection state (WS dot), guild selector, live clock — mono font, reads like an instrument readout.
+
+## 0.1 Motion & 3D Layer (the "lebih kreatif" addition)
+
+### Motion rules (from `motion/react`)
+- **Page transitions:** one shared `RouteTransition` in `(dashboard)/layout.tsx` — `AnimatePresence mode="popLayout"` + `motion.div key={pathname}` (fade + 8px rise + slight blur-out, ~220ms, `easeOut`). Consistent everywhere, zero per-page boilerplate.
+- **Enter choreography (per page, ONE signature moment):** staggered rise-in for the hero/ticker group using `staggerChildren` variants; afterwards, quiet springs for hover/tap (`scale: 1.03` on interactive blocks, `whileTap` on buttons).
+- **Layout animation:** `layout` prop on list items (messages rows, recording rows, queue) so add/remove/filter reflows smoothly; `layoutId` for shared-element transitions (ticker → detail modal on dashboard).
+- **Live pulse:** `motion` drives the severity ticks / speaker rings with springs, not CSS `transition` alone.
+- **`useReducedMotion()`** (from `motion/react`) gates ALL heavy motion; CSS `@media (prefers-reduced-motion: reduce)` additionally kills `scan`/`spin-disc` keyframes. Accessibility floor, non-negotiable.
+- **No scroll-jacking, no marquee loops, no per-element confetti.** One moment per page. (`frontend-design` skill: "Satu momen orkestrasi biasanya lebih mengena daripada efek tersebar.")
+
+### 3D rules (raw `three`, no R3F — lean bundle)
+- Exactly **two** scenes, chosen because they carry real data meaning: **Dashboard hero** (`SignalField` — a particle field whose pulse density reflects live activity) and **Voice page** (`OrbField` — speakers as glowing orbs whose height/ring radius reacts to who is speaking). Everything else stays 2D/motion.
+- **Lazy + client-only:** `next/dynamic(() => import("./SignalField"), { ssr: false, loading: () => <StaticFallback/> })`. Three ships in its own chunk, loaded only on those two routes.
+- **WebGL guard:** if `!window.WebGLRenderingContext` or context creation fails → render the static SVG/CSS fallback (a stylized 2D version of the same visual). Never blank.
+- **Perf guardrails:** `dpr: [1, 1.75]`, `powerPreference: "high-performance"`, `antialias: true`; RAF loop paused on `document.hidden`; `dispose()` geometries/materials on unmount; particle count capped by `navigator.hardwareConcurrency` + viewport (`Math.min(900, w*h/2000)`).
+- **Style:** warm palette ONLY — signal-lime particles, amber/vermilion for flag/warn states; fog + soft additive blending for glow (no harsh white lights, no metallic PBR).
+- **Interactivity:** subtle pointer parallax (camera lerp toward cursor) + gentle idle rotation. No drag/drop, no raycasting menus.
+
+### Per-page metaphor (kills monotony — each page feels different)
+| Route | Metaphor | Signature visual | Motion / 3D |
+|---|---|---|---|
+| `/dashboard` | Live ops overview | **3D signal particle field** hero + asymmetric ticker blocks + radial moderation gauge | **3D SignalField** (reacts to activity), staggered ticker rise-in, gauge draws on mount |
+| `/messages` | Transcript | Left channel **timeline spine**; right = flowing message entries with left **severity tick** (no bordered cards); search = command palette | `layout` on message rows, spring severity ticks, palette types in |
+| `/voice` | Stage | **3D orb field** of speakers + equalizer rings; activity = horizontal **session ribbon** | **3D OrbField** (speaking → orb rises + ring pulses), session ribbon draws sequentially |
+| `/media` | Turntable | Rotating **disc** now-playing; queue = borderless list | CSS 3D disc spin (spring on play/pause), queue `layout` reflow, progress bar springs |
+| `/recordings` | Tape library | Rows with **waveform thumbnail** (custom SVG from duration) | Waveform bars spring on hover; new upload animates in (AnimatePresence) |
+| `/moderation` | Security log | Vertical **event flow** with status nodes (dot + line), not a table of cards | Nodes pulse on live action; timeline draws in sequence |
+| `/analysis` | Query console | Terminal-style search panel | Typing cursor + results stagger |
+
+---
+
+## 1. What to KEEP (reuse verbatim — correct + integrates to backend)
+- `src/lib/api/server.ts` — 11 server fetchers (`getDashboardStats`, `getActivity`, `getMediaStatus`, `getConfig`, `getModerationStats/Actions`, `getGuilds`, `getVoiceStatus`, `getRecordings`, `getMessages`). **No change.**
+- `src/lib/api/client.ts` — `apiRequest` + `ApiError`. **No change.**
+- `src/lib/ws/*` — `connection.ts`, `context.tsx`, `types.ts` (17 typed events: `message_created/updated/deleted/analyzed`, `voice_*`, `media_state`, `voice_pcm_data` binary). **No change.**
+- `src/lib/types/*` — all interfaces. **No change.**
+- `src/lib/format.ts`, `src/lib/utils.ts` (`cn`). **No change.**
+- `src/lib/navigation.ts` — `navItems`. Keep but extend icons/labels if needed.
+- Hooks: `src/hooks/*` (use-dashboard, use-media, use-messages, use-voice, use-moderation, use-recordings, use-guilds, use-config, use-chatbot-user, use-action, use-mobile), `src/lib/hooks/use-mounted.ts`. **Reuse** (verify no bad imports into deleted barrels).
+- Feature logic kept but **reskinned**: `src/components/media/music-player.tsx`, `src/components/voice/*`, `src/components/chatbot/*`, `src/components/messages/*`, `src/components/recordings/*`, `src/components/moderation/moderation-section.tsx`, `src/components/analysis/search-panel.tsx`, `src/components/dashboard/*` (charts → rewritten as custom SVG).
+
+## 2. What to DELETE
+- `src/components/ui/*` (all 50 shadcn primitives).
+- `components.json`, `@shadcn/react` + `@base-ui/react` + `shadcn` deps.
+- `recharts` (replace with custom SVG chart helpers in `src/components/charts/`).
+- `src/app/globals.css` → rewrite (no `@import "shadcn/tailwind.css"`, no `--color-primary` teal, no `.glass*`, no `.text-gradient`/`.gradient-border` teal/purple, no bluish body texture).
+- `src/components/layout/app-sidebar.tsx` (shadcn Sidebar) → replace with custom `Spine` nav.
+- All `page.tsx`+`view.tsx` pairs → merge into single `page.tsx` per route.
+
+## 3. What to BUILD (new)
+- New `globals.css` (tokens above + utilities + keyframes `scan`, `eq`, `fade-up`, `spin-disc`).
+- `src/components/primitives/` — minimal custom: `Button`, `Input`, `Select`, `Dialog`, `Tooltip`, `Badge`, `Progress`, `Avatar`, `Skeleton`, `Toast`, `Sheet`.
+- `src/components/motion/` — `RouteTransition.tsx`, `Stagger.tsx`, `variants.ts`.
+- `src/components/three/` — `SignalField.tsx`, `OrbField.tsx`, `WebGLGuard.tsx`, `StaticFallback.tsx`, `useThreeScene.ts`.
+- `src/components/charts/` — `Sparkline`, `AreaActivity`, `RadialGauge`, `SessionRibbon`, `Waveform`.
+- `src/components/layout/` — `Spine.tsx`, `StatusBar.tsx`, `ThemeToggle.tsx` (reskin).
+- 7 merged `page.tsx` files (one per route) implementing the metaphors above.
+- `src/app/layout.tsx` — root (fonts + ThemeProvider + Toaster), `src/app/(dashboard)/layout.tsx` — providers + Spine + StatusBar + RouteTransition + MiniPlayer + Chatbot, `src/app/page.tsx` → redirect `/dashboard`.
+
+---
+
+## 4. Target File & Folder Structure (authoritative)
+
+Everything below `services/frontend/src/` is the new tree. `REWRITE` replaces existing; `NEW` creates; `DELETE` removes. The `app/` route tree collapses `page.tsx`+`view.tsx` into single `page.tsx` files containing BOTH server fetch (default export) and client view (`"use client"` named export in same file).

+
+### 4.1 Single-file page pattern (mandatory)
+```tsx
+// server component (default export) — runs on the server, fetches initial data
+import { getX, getY } from "@/lib/api/server";
+import { XView } from "./page"; // self-import of the named client export
+
+export default async function Page() {
+  const [a, b] = await Promise.allSettled([getX(), getY()]);
+  return <XView initialA={a.status === "fulfilled" ? a.value : undefined}
+                  initialB={b.status === "fulfilled" ? b.value : undefined} />;
+}
+
+// client component (named export) — hydrated, takes initialData as SWR fallback
+"use client";
+export function XView({ initialA, initialB }: Props) {
+  const { data } = useX(initialA); // SWR fallbackData = initialA
+}
+```
+Self-referencing the named export keeps the file single-artifact while satisfying Next's RSC boundary (default = server, named = client). Tabs live inside `XView`.
+
+### 4.2 Import rules (lint gate)
+- No `@/components/ui/*` (deleted) — all UI via `@/components/primitives`.
+- `three` only imported inside `src/components/three/*`; pages import those via `next/dynamic({ ssr: false })`.
+- `motion` imported from `motion/react` only.
+- All data: `@/lib/api/server` (server) / `@/lib/api/client` (client) — never invented endpoints.
+
+---
+
+## TASKS (granular — every file is its own task)
+
+### PHASE 0 — Dependency surgery
+- **T0.1** Edit `package.json`: remove `dependencies["@base-ui/react"]`.
+- **T0.2** Remove `dependencies["@shadcn/react"]`.
+- **T0.3** Remove `dependencies["shadcn"]`.
+- **T0.4** Remove `dependencies["recharts"]`.

+- **T0.12** `rm -f pnpm-lock.yaml && pnpm install` (regenerate lockfile).
+- **T0.13** Verify `pnpm ls recharts @shadcn/react @base-ui/react` → empty; `pnpm ls motion three @types/three` → present.
+- **T0.14** `cat pnpm-workspace.yaml`: confirm `onlyBuiltDependencies` keeps needed native builds, no broken shadcn postinstall.
+
+### PHASE 1 — Design tokens (globals.css)
+- **T1.1** Rewrite `@theme { }` head: light `:root` palette from §0 (canvas/surface/ink/ink-soft/hairline/signal/signal-ink/amber/vermilion/ring).
+- **T1.2** Add radius tokens `--r: 14px`, `--r-panel: 12px`, `--r-control: 8px`, `--r-pill: 9999px`.
+- **T1.3** Add `--font-display` token; keep `--font-sans`/`--font-mono`.
+- **T1.4** Add `.dark { }` override block with §0 dark values (warm charcoal).
+- **T1.5** Replace `@layer base body` bg: warm dot-grid `radial-gradient(oklch(0.45 0.03 70 / 0.05) 1px, transparent 1px)` + faint warm glow; remove old bluish radial layers.

+- **T1.7** Delete `.glass`, `.glass-elevated`, `.glass-intense`, `.dark .glass-intense` utilities.
+- **T1.8** Delete `.text-gradient` and `.gradient-border`.
+- **T1.9** Add `.surface` utility (bg var(--surface), radius var(--r), padding).
+- **T1.10** Add `.scan-tick` (1px animated pulse line, keyframe `scan`).
+- **T1.11** Add `.ticker`, `.pill`, `.mono` utilities.
+- **T1.12** Add keyframes `scan`, `eq`, `fade-up`, `spin-disc` (keep used existing ones if still referenced).
+- **T1.13** Add `@media (prefers-reduced-motion: reduce)` kill switch for scan/eq/spin-disc/pulse-ring/shimmer.
+- **T1.14** Remove `@import "shadcn/tailwind.css";` (line 3); verify nothing else depends on shadcn CSS vars.
+- **T1.15** Verify `grep -c "0.52 0.17 215\|0.55 0.2 280" src/app/globals.css` → `0`.
+- **T1.16** `pnpm biome check src/app/globals.css` → no errors.
+
+### PHASE 2 — Root layout + fonts
+- **T2.1** In `layout.tsx` add `Bricolage_Grotesque` (`variable: "--font-display"`, subsets `["latin"]`, `display: "swap"`).
+- **T2.2** Apply `inter.variable`, `jetbrainsMono.variable`, `bricolage.variable` to `<html>`.
+- **T2.3** Remove `import { Toaster } from "@/components/ui/sonner"`.
+- **T2.4** Comment out `<Toaster />` temporarily (re-enabled after T3.10).
+- **T2.5** Keep `suppressHydrationWarning`, `ThemeProvider` (defaultTheme dark, enableSystem false).
+- **T2.6** `npx tsc --noEmit` (fonts only; rest may still error until primitives exist).
+
+### PHASE 3 — Custom primitives (replace 50 shadcn ui)
+- **T3.1** `primitives/Button.tsx`: `motion.button`, variants `primary`/`ghost`/`danger`, `cn()` merge, `cursor-pointer`, `focus-visible:ring-2 ring-signal`, `whileTap` scale 0.97 gated by `useReducedMotion()`.
+- **T3.2** `primitives/Input.tsx`: native `<input>`, `bg-surface`, `rounded-[var(--r-control)]`, `mono` prop.
+- **T3.3** `primitives/Select.tsx`: native `<select>` styled, `bg-surface`.
+- **T3.4** `primitives/Dialog.tsx`: native `<dialog>` + `showModal()`, warm `::backdrop`, `AnimatePresence`, `onClose`.
+- **T3.5** `primitives/Tooltip.tsx`: CSS group-hover popover.
+- **T3.6** `primitives/Badge.tsx`: tonal pill, `variant` → `bg-{tone}/15 text-{tone}` (signal/amber/vermilion/neutral).
+- **T3.7** `primitives/Progress.tsx`: SVG track + `motion` fill, `value`/`max`, signal color.
+- **T3.8** `primitives/Avatar.tsx`: `<img>` + initials fallback, signal bg, size prop.
+- **T3.9** `primitives/Skeleton.tsx`: shimmer block (signal-tinted), `aria-hidden`.
+- **T3.10** `primitives/Toast.tsx`: `ToastProvider` context + portal, `useToast()`, motion slide-in, auto-dismiss.
+- **T3.11** `primitives/Sheet.tsx`: mobile drawer (`translate-x` spring), overlay, `open`/`onClose`.
+- **T3.12** `primitives/index.ts` re-export all 11.
+- **T3.13** Re-enable `<Toaster />` in `layout.tsx` (T2.4).
+- **T3.14** Verify `npx tsc --noEmit` on primitives; `grep -rl "@/components/ui/" src/components/primitives` → empty.
+
+### PHASE 4 — Motion foundation
+- **T4.1** `motion/variants.ts`: export `spring`, `ease`, `fadeUp`, `stagger` (per §0.1).
+- **T4.2** `motion/Stagger.tsx`: `StaggerGroup` + `StaggerItem` (`"use client"`).
+- **T4.3** `motion/RouteTransition.tsx`: `"use client"`, `usePathname`, `AnimatePresence mode="popLayout"`, reduced-motion fallback to plain `<div>`.

+
+### PHASE 5 — Custom SVG charts (replace recharts)

+- **T5.6** Verify `npx tsc --noEmit` on charts; no `recharts` import.
+
+### PHASE 6 — Three.js foundation (lazy, guarded)
+- **T6.1** `three/WebGLGuard.tsx`: `"use client"`, detect webgl2/webgl, render `children` or `fallback`.
+- **T6.2** `three/useThreeScene.ts`: shared hook — renderer init (`dpr:[1,1.75]`, `powerPreference`), RAF with `document.hidden` pause, `dispose()` on unmount, resize observer.
+- **T6.3** `three/SignalField.tsx`: `Points` BufferGeometry (~min(900, w*h/2000)), additive blend, signal-lime, fog, idle rotation + sine drift, `activity` prop, pointer parallax. Uses `useThreeScene`.
+- **T6.4** `three/OrbField.tsx`: per-speaker `Sphere`, y-scale + ring lerp to speaking, tones signal/idle/vermilion.

+- **T7.3** `layout/ThemeToggle.tsx`: restyle, keep `next-themes` logic, motion icon swap.
+- **T7.4** Rewrite `(dashboard)/layout.tsx`: keep SWRConfig/WsProvider/MediaPlayerProvider/ChatbotProvider + sync functions verbatim; swap `AppSidebar`→`Spine`, header→`StatusBar`, wrap children in `RouteTransition`; remove `SidebarInset`/`SidebarTrigger`/`Separator`; keep MiniPlayer+ChatbotContainer.
+- **T7.5** Delete `layout/app-sidebar.tsx`.
+- **T7.6** Verify `grep -rl "components/ui/sidebar\|app-sidebar" src` → empty; `npx tsc --noEmit`.
+
+### PHASE 8 — Dashboard page + components

+- **T11.4** Verify `npx tsc --noEmit`; no `components/ui/card` in media tree.
+
+### PHASE 12 — Recordings page + components

+
+### PHASE 13 — Moderation + Analysis pages

+- **T13.2** Rewrite `moderation/moderation-section.tsx` → event-flow, no Card/table.
+- **T13.3** Rewrite `analysis/page.tsx`: client `<AnalysisView/>` terminal console (`primitives/Input` mono + blinking caret, `.surface` results staggered).
+- **T13.4** Rewrite `analysis/search-panel.tsx` → terminal style.
+- **T13.5** Verify `npx tsc --noEmit`.
+
+### PHASE 14 — Chatbot + shared + final cleanup
+- **T14.1** Rewrite `chatbot/chatbot-container.tsx` → `.surface`, keep drag/minimize.
+- **T14.2** Rewrite `chatbot/chat-panel.tsx` → bubbles via `AnimatePresence`, `primitives/*`.
+- **T14.3** Keep `chatbot/chatbot-context.tsx` + `index.ts`.
+- **T14.4** Rewrite `shared/empty-state.tsx` → tonal.
+- **T14.5** Rewrite `shared/error-state.tsx`.

+- **T14.7** Rewrite `shared/error-boundary.tsx`.
+- **T14.8** Rewrite `shared/guild-selector.tsx` → `primitives/Select`.
+- **T14.9** `rm -rf src/components/ui && rm -f components.json`.
+- **T14.10** `grep -rn "components/ui/\|@shadcn\|@base-ui\|recharts" src` → MUST be empty.
+- **T14.11** `grep -rl "from \"recharts\"\|@base-ui\|@shadcn" src` → empty (double-check).
+- **T14.12** Verify `npx tsc --noEmit` across whole `src`.
+
+### PHASE 15 — Build + lint gate
+- **T15.1** `cd services/frontend && npx tsc --noEmit` → 0 errors.
+- **T15.2** `pnpm biome check` → fix all issues (no `any` in new files).
+- **T15.3** `pnpm build` (standalone) → success, emits `.next/standalone/server.js`.
+- **T15.4** Inspect `.next/static/chunks/` for three-heavy chunk loaded only on dashboard/voice; confirm NOT in `/dashboard/` initial SSR HTML.
+- **T15.5** Confirm `pnpm-lock.yaml` present (reproducible flake install).
+- **T15.6** `grep -c "0.52 0.17 215\|0.55 0.2 280" .next/static/css/*.css` → 0.
+
+### PHASE 16 — Local runtime smoke test (no prod)
+- **T16.1** Start local standalone: `GMW_BACKEND_URL=http://127.0.0.1:4001 PORT=4017 node .next/standalone/server.js &`.
+- **T16.2** `curl -s -o /dev/null -w "%{http_code}"` for all 7 routes → 200.
+- **T16.3** `curl /dashboard/ | grep -o "Bricolage\|signal\|surface"` → present.
+- **T16.4** `curl /_next/static/css/*.css | grep "0.52 0.17 215\|0.55 0.2 280"` → empty.
+- **T16.5** Headless browser `/dashboard/`+`/voice/` WebGL on: no console errors, `<canvas>` present, `<StaticFallback/>` NOT rendered.
+- **T16.6** Same pages WebGL off: `<StaticFallback/>` renders, no crash.
+- **T16.7** Kill local server. Do NOT touch prod unit.
+- **T16.8** Confirm 7 routes 200 + no console errors in T16.5/16.6.
+
+### PHASE 17 — Flake + staging deploy
+- **T17.1** Inspect `flake.nix` frontend drv: `filterSource` ignores `out/.next/node_modules`; `pnpm-lock.yaml` included.
+- **T17.2** `nix build .#gmw-frontend --impure --sandbox-off` → succeeds.
+- **T17.3** `nix copy` frontend drv to VPS into staging profile (test port e.g. 4217).
+- **T17.4** Create/adjust staging systemd unit with `PORT=4217` exported BEFORE `node server.js` (LIDM PORT bug).
+- **T17.5** `sudo systemctl restart gmw-frontend-staging`; `curl` staging → 200.
+- **T17.6** Browser-check staging `/dashboard/`+`/voice/` (3D visible, fallback test).
+- **T17.7** Verify staging CSS has no old teal/purple; new design renders.
+
+### PHASE 18 — Production swap (CONFIRM WITH USER FIRST)
+- **T18.1** STOP — send staging screenshots/URL; await explicit approval before touching prod.
+- **T18.2** On approval: `nix-env --profile /nix/var/nix/profiles/gmw-frontend --set <new-drv>`.
+- **T18.3** Confirm `gmw-frontend.service` exports `PORT=4017` before exec.
+- **T18.4** `sudo systemctl restart gmw-frontend`.
+- **T18.5** `curl` all 7 routes on `https://imphnen.asepharyana.my.id` → 200.
+- **T18.6** Browser verify prod: new design, old teal gone, 3D scenes render.
+- **T18.7** `journalctl -u gmw-frontend -f` 5 min; confirm WS reconnect + live features.
+- **T18.8** Notify user with before/after notes; keep rollback plan (`nix-env --set <previous>; systemctl restart`).
+
+---
+
+## Risks / Trade-offs
+- **Scope:** 7 pages + charts + primitives + motion + 2 three scenes + layout. Big but mechanical; each task is isolated (~90 atomic tasks).
+- **Bundle weight:** `three` adds ~150KB gz but ONLY on dashboard/voice routes (lazy chunk, `ssr:false`). `motion` ~35KB gz app-wide — acceptable.
+- **WebGL compatibility:** covered by `WebGLGuard` + static fallback. Old devices / strict privacy browsers never blank.
+- **Motion excess:** risk of "AI-generated" scattered animation. Guard: one signature moment per page, shared variants, reduced-motion gates.
+- **Feature regressions:** Voice PCM playback, media transport, chatbot drag — logic preserved, only skin changes. Smoke test (T16) catches SSR breaks; live WS/3D needs real backend (staging T17).
+- **Removed deps:** dropping `recharts`/`sonner`/`cmdk` means rewriting charts + toasts + search palette — accounted for in Phases 3/5/9.
+- **Next standalone PORT bug:** `server.js` may not read `PORT` — ensure unit exports `PORT=4017` before exec (T17.4/T18.3).
+- **three + React 19:** raw three avoids R3F compat surface; lifecycle (dispose + RAF) handled in T6.2.
+- **next-themes:** keep (light/dark toggle); default dark.
+
+## Open questions (answer before T18)
+- Q1: Deploy to prod now or staging-only first? (Recommend staging + screenshot review.)
+- Q2: Keep `react-day-picker`/`embla` if any page still needs them? (Plan assumes no — verify in T14.10 grep.)
+- Q3: Any brand name/wordmark change from "Discord Automod"? (Keep "Bete" identity unless told.)
+- Q4: 3D depth — full 3D scenes on dashboard+voice as specced, or also a 3D accent on media (disc)? (Default: dashboard+voice only; media disc stays CSS 3D.)

+# GMW — Moderation Explainability (#1) + Semantic Search (#3) Implementation Plan
+
+> **For Hermes:** Use subagent-driven-development to implement task-by-task.
+> Hard constraint from user (2026-08-18): web is PUBLIC, read-only, for USERS not admins. Moderation MUST stay FULLY AUTOMATIC. Rules stay in CODE (no per-channel config UI).
+
+**Goal:** Make GMW transparent (users see why a message was moderated) and searchable (users can semantic-search the message corpus), via two fully-automatic, code-driven, read-only-public features.
+
+**Architecture:**
+- **#1 Explainability:** Persist the structured moderation verdict that already exists in `AnalysisResult` (`flags[]`, `categories[]`, `severity`, `confidence`, `evidence[]`) into new columns on `moderation_actions`, surface them through the existing public moderation oRPC + the existing public `moderation` dashboard view. No new behavior — only new *data* + new *read* paths.
+- **#3 Semantic Search:** Add a SECOND persistent Qdrant collection (`gmw_message_archive`) keyed by message id (NOT the TTL cache). Embed each captured text message at capture time (reuse `embedText`) and upsert. Add a public `messages.semanticSearch` oRPC + a read-only search UI on the public `messages` view. Best-effort / non-blocking — embed failures never affect moderation or capture.
+
+**Tech Stack:** TypeScript (discord-gateway + backend + frontend monorepo), Drizzle ORM + Postgres (PgBouncer on imrnes), Qdrant (100.121.180.82:6333), Next.js 16 App Router + shadcn/ui, oRPC over `/trpc`. pnpm. Deploy via GitHub Actions Nix build + `systemctl restart`.
+
+**Critical existing facts (verified in repo):**
+- `AnalysisResult` shape (`src/modules/ai-moderation/ai-analysis-worker.ts:55`): `messageId, status, flags[], categories[], severity, confidence, recommendedAction, score, analysis, correctedFlags?`. The shared `AnalysisResult` (`src/shared/moderation-types.ts:142`) ALSO has `evidence?: string[]` and `policyVersion?: string`. **THESE ARE ALREADY COMPUTED but only logged, never persisted to `moderation_actions`.**
+- `moderation_actions` schema is DEFINED TWICE with a divergence:
+  - `src/shared/database/schema.ts:638` → `pgModerationActionsTable` (authoritative, has `reset_nickname` in `action_type` enum).
+  - `src/shared/database/schema/messages.ts:25` → another `pgModerationActionsTable` (NO `reset_nickname`; gateway-local copy).
+  - The gateway's `ModerationActionsDb` (`src/modules/message-capture/moderationActionsDb.ts`) imports from `schema.ts` (the authoritative one). The `messages.ts` copy appears UNUSED for DB ops — but WE MUST ADD NEW COLUMNS TO BOTH to avoid type drift, OR confirm the `messages.ts` copy is dead and delete it. **Decision: add columns to `schema.ts` (authoritative) AND the `messages.ts` copy to keep `$inferInsert`/`$inferSelect` in sync (the gateway `ModerationAction` type flows from shared).** Verify with grep that `messages.ts` `pgModerationActionsTable` is not used by any `.insert()`/`.select()` at runtime before relying on it; if only re-exported, we still patch it for type-safety.
+- Migration mechanism: Drizzle-managed via `drizzle/migrations/*.sql` (journal `_journal.json`) applied by `runMigrations()` → `migratePostgres`. **New tables/columns must be added with `drizzle-kit generate` to produce a numbered `.sql` + journal entry**, OR (simpler, matches `0013_rename_*.sql` manual style) write a raw idempotent `.sql` under `drizzle/migrations/` AND register it in `_journal.json`. **Preferred here: use `pnpm drizzle-kit generate` so the journal stays consistent.** The legacy `src/shared/database/migrations/001_drop_unused_ai_columns.sql` is a PRE-drizzle manual script — do NOT follow that pattern.
+- **Historical lesson (MUST respect):** a prior migration (`0004_drop_unused_ai_columns.sql` = old `001_drop`) DELETED `ai_evidence`, `ai_policy_version`, `ai_moderation_raw` from `messages` with the note "written but never read". → Our new `moderation_actions` columns MUST be read (serializer + FE render). No write-only columns.
+- Embedding client: `embedText(text)` / `embedTexts(texts[])` in `src/modules/ai-moderation/embeddingClient.ts`. Returns `null` if `AI_LLM_EMBEDDING_MODEL` not configured. Reuses `config.AI_LLM_BASE_URL` + `config.AI_LLM_API_KEY`. OpenAI SDK v6 → `encoding_format: "float"` REQUIRED (Nvidia rejects base64).
+- Qdrant client: `src/modules/ai-moderation/qdrantClient.ts`. Has `ensureQdrantCollection(vectorSize)`, `upsertQdrantPoint(cacheKey, vector, payload)`, `searchQdrant(vector, limit, scoreThreshold)`. These are hardcoded to the cache collection name `config.QDRANT_COLLECTION ?? "gmw_text_moderation"`. **#3 needs a second collection** → generalize the client to accept a collection name param (add `ensureQdrantCollectionV2(name, size)` / `upsertQdrantPointV2(name, id, vector, payload)` / `searchQdrantV2(name, vector, limit, scoreThreshold)` OR refactor `collectionName()` to take an arg). Keep the cache path unchanged.
+- Capture hook: `captureMessage()` (`src/modules/message-capture/messageCapture.ts:201`) calls `messageStore.upsertMessageForCapture(messageRecord)` then (if not backlog) `queueMessageAnalysis`. **#3 embed must happen here**, async + fire-and-forget, after successful insert.
+- Public moderation view: `services/frontend/src/app/(dashboard)/moderation/view.tsx` renders `ActionRow` per action. The `ModerationAction` FE type is in `services/frontend/src/lib/types/moderation.ts` (NO new fields yet). The backend `moderationService.listActions` SQL is in `services/backend/src/modules/moderation/moderation.repository.ts:68` (raw SQL, selects fixed columns, joins `messages`).
+- oRPC wiring: `services/backend/src/orpc/router.ts` → `moderationRouter` (stats, actions) and `messagesRouter` (list, byChannel, getById, review, attachments). New procedures added here.
+
+---
+
+## TASK 1 — Schema: add explainability columns to `moderation_actions`
+
+**Objective:** Persist structured verdict on moderation actions so it can be surfaced (read) later.
+
+**Files:**
+- Modify: `services/discord-gateway/src/shared/database/schema.ts` (authoritative `pgModerationActionsTable`, ~line 638)
+- Modify: `services/discord-gateway/src/shared/database/schema/messages.ts` (`pgModerationActionsTable` copy, ~line 25) to keep type in sync
+- Create: `services/discord-gateway/drizzle/migrations/0015_add_moderation_explainability.sql`
+- Update: `services/discord-gateway/drizzle/migrations/meta/_journal.json` (add new entry)
+
+**Step 1: Add columns to both schema definitions**
+Add after `executed_at` in BOTH `pgModerationActionsTable` definitions:
+```ts
+    // ── Explainability (structured verdict, surfaced read-only to public web) ──
+    flags: pgText("flags"),            // JSON array of string flags, e.g. ["sara_agama","vulgar"]
+    categories: pgText("categories"), // JSON array of category strings
+    severity: pgText("severity", {
+      enum: ["none", "low", "medium", "high", "critical"],
+    }),
+    confidence: pgReal("confidence"),  // 0..1
+    score: pgReal("score"),            // 0..1 raw model score
+    evidence: pgText("evidence"),      // JSON array of short quoted snippets
+    policy_version: pgText("policy_version"), // rules.ts policy version string
+```
+Note: `flags`/`categories`/`evidence` stored as JSON-stringified TEXT (consistent with how `messages.ai_moderation_flags`/`ai_categories` are stored as TEXT elsewhere — confirm storage format in `updateMessageAIAnalysis`). Keep nullable.
+
+**Step 2: Generate/author the migration SQL**
+`0015_add_moderation_explainability.sql` (idempotent):
+```sql
+-- Add structured explainability columns to moderation_actions (read-only surfaced to public web).
+ALTER TABLE IF EXISTS "moderation_actions"
+  ADD COLUMN IF NOT EXISTS "flags" text,
+  ADD COLUMN IF NOT EXISTS "categories" text,
+  ADD COLUMN IF NOT EXISTS "severity" text
+    CHECK ("severity" IS NULL OR "severity" IN ('none','low','medium','high','critical')),
+  ADD COLUMN IF NOT EXISTS "confidence" real,
+  ADD COLUMN IF NOT EXISTS "score" real,
+  ADD COLUMN IF NOT EXISTS "evidence" text,
+  ADD COLUMN IF NOT EXISTS "policy_version" text;
+```
+Register in `_journal.json`: append an entry with `idx: 15`, a new unique `tag` (hash), `version`, `when` = Date.now(), `tag` short, `breakpoints: false`. Use `pnpm drizzle-kit generate` if possible to get a correct tag; otherwise hand-edit the journal carefully (copy an existing entry's shape).
+
+**Step 3: Type-check gateway**
+Run: `cd services/discord-gateway && pnpm typecheck`
+Expected: PASS (no new compile errors).
+
+**Step 4: Commit**
+```bash
+git add services/discord-gateway/src/shared/database/schema.ts \
+        services/discord-gateway/src/shared/database/schema/messages.ts \
+        services/discord-gateway/drizzle/migrations/0015_add_moderation_explainability.sql \
+        services/discord-gateway/drizzle/migrations/meta/_journal.json
+git commit -m "feat(db): add explainability columns to moderation_actions"
+```
+
+---
+
+## TASK 2 — Persist verdict at the auto-delete + command-handler call sites
+
+**Objective:** Populate the new columns from the already-computed `AnalysisResult` when a moderation action is logged. Fully automatic, no new behavior.
+
+**Files:**
+- Modify: `services/discord-gateway/src/modules/ai-moderation/autoDeleteManager.ts` (`logAutoDeleteAttempt` ~line 166, and the second `createModerationAction` call ~line 234 for nickname/mute paths)
+- Modify: `services/discord-gateway/src/modules/command-handler/moderation.handler.ts` (`createModerationAction` ~line 95)
+- Helper (create): `services/discord-gateway/src/modules/ai-moderation/verdictToActionFields.ts` — shared mapper so all 3 call sites stay DRY.
+
+**Step 1: Create the mapper helper**
+`verdictToActionFields.ts`:
+```ts
+import type { AnalysisResult } from "@/modules/ai-moderation/ai-analysis-worker";
+import type { ModerationActionInsert } from "@/shared/index"; // or inline shape
+
+/**
+ * Map a computed AI verdict into the explainability columns of a moderation
+ * action. Null-safe: missing fields stay null (e.g. manual admin actions have
+ * no AnalysisResult). This is read-only structured data — it does NOT change
+ * any enforcement decision.
+ */
+export function verdictToActionFields(result?: {
+  flags?: string[];
+  categories?: string[];
+  severity?: string;
+  confidence?: number;
+  score?: number;
+  evidence?: string[];
+  policyVersion?: string;
+}): {
+  flags: string | null;
+  categories: string | null;
+  severity: string | null;
+  confidence: number | null;
+  score: number | null;
+  evidence: string | null;
+  policy_version: string | null;
+} {
+  if (!result) {
+    return { flags: null, categories: null, severity: null, confidence: null,
+             score: null, evidence: null, policy_version: null };
+  }
+  const j = (v: unknown) => (v == null ? null : JSON.stringify(v));
+  return {
+    flags: j(result.flags),
+    categories: j(result.categories),
+    severity: result.severity ?? null,
+    confidence: result.confidence ?? null,
+    score: result.score ?? null,
+    evidence: j(result.evidence),
+    policy_version: result.policyVersion ?? null,
+  };
+}
+```
+
+**Step 2: Wire `logAutoDeleteAttempt`**
+Find the `createModerationAction({...})` in `logAutoDeleteAttempt` and spread the verdict fields:
+```ts
+await messageStore.createModerationAction({
+  message_id: message.id,
+  user_id: message.user_id,
+  guild_id: message.guild_id,
+  action_type: "delete_message",
+  reason: result.reason,
+  ...verdictToActionFields(result.analysisResult), // <-- pass the AnalysisResult through
+  executed_by: "auto-delete-manager",
+  status: ...,
+});
+```
+**IMPORTANT:** `result` here is `AutoDeleteResult` — verify it carries the `AnalysisResult` (or the verdict). If `AutoDeleteResult` does NOT carry the full `AnalysisResult`, trace where `attemptAutoDeleteFlaggedMessage` is called from and pass the `AnalysisResult` down (it is available in the analysis worker that triggered the delete). Confirm by reading `AutoDeleteResult` type + its producer. If the verdict is only available at the orchestrator level, add an optional `verdict?: AnalysisResult` field to `AutoDeleteResult` and populate it at the call site.
+
+**Step 3: Wire the second call site in `autoDeleteManager.ts`** (the mute/nickname path ~line 234) similarly, if it has an `AnalysisResult` available; otherwise leave fields null (manual-style action).
+
+**Step 4: Wire `moderation.handler.ts`** command path (~line 95) — pass `verdictToActionFields(verdict)` if the command handler has the `AnalysisResult` for the target message; otherwise nulls. Confirm what the handler receives.
+
+**Step 5: Type-check + lint**
+Run: `cd services/discord-gateway && pnpm typecheck && pnpm lint`
+Expected: PASS.

+
+## TASK 3 — Backend: surface explainability in `moderation.actions`
+
+**Objective:** Read the new columns in the public oRPC so the frontend can render them. (Read path — satisfies the "never write-only" rule.)
+
+**Files:**
+- Modify: `services/backend/src/modules/moderation/moderation.repository.ts` (`listActions` raw SQL ~line 68) — add new columns to SELECT + map.
+- Modify: `services/frontend/src/lib/types/moderation.ts` (`ModerationAction` interface) — add new fields.
+- Modify: `services/frontend/src/app/(dashboard)/moderation/view.tsx` (`ActionRow`) — render flags/categories badges + severity + confidence + evidence snippet.
+
+**Step 1: Extend backend SELECT**
+In `listActions`, add to the SELECT list: `a.flags, a.categories, a.severity, a.confidence, a.score, a.evidence, a.policy_version`. In the `.map(...)` add:
+```ts
+flags: r.flags ? safeJsonArray(String(r.flags)) : null,
+categories: r.categories ? safeJsonArray(String(r.categories)) : null,
+severity: r.severity ? String(r.severity) : null,
+confidence: r.confidence != null ? Number(r.confidence) : null,
+score: r.score != null ? Number(r.score) : null,
+evidence: r.evidence ? safeJsonArray(String(r.evidence)) : null,
+policy_version: r.policy_version ? String(r.policy_version) : null,
+```
+where `safeJsonArray(s)` = `JSON.parse(s)` wrapped in try/catch returning `[]` on failure (define a tiny local helper in the repository file).
+
+**Step 2: Extend FE type**
+In `services/frontend/src/lib/types/moderation.ts` `ModerationAction`:
+```ts
+  flags: string[] | null;
+  categories: string[] | null;
+  severity: "none" | "low" | "medium" | "high" | "critical" | null;
+  confidence: number | null;
+  score: number | null;
+  evidence: string[] | null;
+  policy_version: string | null;
+```
+
+**Step 3: Render in `ActionRow`**
+After the existing reason block, add (using existing `Badge` + `aiTone` from `@/lib/ai-status`):
+```tsx
+{a.severity && (
+  <Badge tone={aiTone(a.severity === "none" ? "clean" : a.severity)}>
+    {a.severity}
+  </Badge>
+)}
+{a.flags?.length ? (
+  <div className="mt-1 flex flex-wrap gap-1">
+    {a.flags.map((f) => <Badge key={f} tone="amber">{f}</Badge>)}
+  </div>
+) : null}
+{a.evidence?.length ? (
+  <div className="mt-1 text-xs text-ink-faint border-l-2 border-hairline pl-2">
+    “{a.evidence[0]}”
+  </div>
+) : null}
+{a.confidence != null && (
+  <div className="mono mt-0.5 text-[0.6rem] text-ink-faint">
+    conf {(a.confidence * 100).toFixed(0)}%
+  </div>
+)}
+```
+Keep `ActionRow` read-only. No admin controls.
+
+**Step 4: Type-check both services**
+Run: `cd services/backend && pnpm typecheck && pnpm lint` and `cd services/frontend && pnpm typecheck && pnpm lint`
+Expected: PASS.
+
+**Step 5: Commit**
+```bash
+git add services/backend/src/modules/moderation/moderation.repository.ts \
+        services/frontend/src/lib/types/moderation.ts \
+        services/frontend/src/app/\(dashboard\)/moderation/view.tsx

+
+## TASK 4 — Qdrant client: support a second persistent collection
+
+**Objective:** Generalize the Qdrant client so #3 can use a dedicated archive collection without disturbing the automod cache.
+
+**Files:**
+- Modify: `services/discord-gateway/src/modules/ai-moderation/qdrantClient.ts`
+
+**Step 1: Add collection-aware variants**
+Refactor `collectionName()` to accept an optional name, and add V2 functions that take an explicit collection:
+```ts
+function collectionName(fallback = config.QDRANT_COLLECTION ?? "gmw_text_moderation"): string {
+  return fallback;
+}
+export const ARCHIVE_COLLECTION = config.QDRANT_ARCHIVE_COLLECTION ?? "gmw_message_archive";
+
+export async function ensureQdrantCollectionV2(name: string, vectorSize: number): Promise<boolean> {
+  // same body as ensureQdrantCollection but uses `name` instead of collectionName()
+}
+export async function upsertQdrantPointV2(
+  name: string, pointId: number, vector: number[], payload: QdrantVerdictPayload,
+): Promise<boolean> { /* PUT /collections/{name}/points with wait:true */ }
+export async function searchQdrantV2(
+  name: string, vector: number[], limit: number, scoreThreshold: number,
+): Promise<QdrantSearchHit[]> { /* POST /collections/{name}/points/search */ }
+```
+Keep all existing `ensureQdrantCollection` / `upsertQdrantPoint` / `searchQdrant` UNCHANGED (cache path). V2 functions mirror them with the `name` param. Reuse `request()` and the existing payload/score types.
+
+**Step 2: Type-check**
+Run: `cd services/discord-gateway && pnpm typecheck`
+Expected: PASS.
+
+**Step 3: Commit**
+```bash
+git add services/discord-gateway/src/modules/ai-moderation/qdrantClient.ts
+git commit -m "feat(qdrant): add collection-aware V2 upsert/search for archive"
+```
+
+---
+
+## TASK 5 — Capture-time embed + archive upsert
+
+**Objective:** Make every (non-backlog, text) captured message searchable in the persistent archive. Non-blocking / best-effort.
+
+**Files:**
+- Modify: `services/discord-gateway/src/modules/message-capture/messageCapture.ts` (`captureMessage` ~line 201)
+- Create: `services/discord-gateway/src/modules/message-capture/archiveEmbedder.ts` — wraps embed + upsert with fire-and-forget + rate-limit guard.
+
+**Step 1: Create `archiveEmbedder.ts`**
+```ts
+import { createChildLogger } from "@/shared/logger/index";
+import { embedText } from "@/modules/ai-moderation/embeddingClient";
+import { ARCHIVE_COLLECTION, ensureQdrantCollectionV2, upsertQdrantPointV2, qdrantPointId } from "@/modules/ai-moderation/qdrantClient";
+import { config } from "@/shared/config/config";
+
+const log = createChildLogger("archive-embedder");
+
+/**
+ * Fire-and-forget: embed a captured message and upsert into the persistent
+ * archive collection. Failures are swallowed — searching is a nice-to-have,
+ * never a precondition for capture or moderation.
+ */
+export function archiveMessageEmbedded(message: {
+  id: string; content: string; username: string; channel_id: string; guild_id: string; created_at: number;
+}): void {
+  if (!config.AI_LLM_EMBEDDING_MODEL) return; // embeddings disabled → skip
+  if (!message.content || message.content.trim().length < 3) return;
+  void (async () => {
+    try {
+      const vector = await embedText(message.content);
+      if (!vector) return;
+      const ok = await ensureQdrantCollectionV2(ARCHIVE_COLLECTION, vector.length);
+      if (!ok) return;
+      await upsertQdrantPointV2(ARCHIVE_COLLECTION, qdrantPointId(`archive:${message.id}`), vector, {
+        text: message.content.slice(0, 4000),
+        flags: "", // not a verdict payload; keep shape compatible
+        analyzed_at: Date.now(),
+        expires_at: Date.now() + 1000 * 60 * 60 * 24 * 365 * 5, // 5y persistent
+        content_hash: undefined,
+      });
+    } catch (err) {
+      log.debug({ messageId: message.id, error: err instanceof Error ? err.message : String(err) }, "archive embed skipped");
+    }
+  })();
+}
+```
+Payload type reuse: `QdrantVerdictPayload` has `text`, `flags`, `analyzed_at`, `expires_at`, `content_hash?`. For the archive we only need `text` + timestamps; set `flags: ""` (empty, ignored by search filter which keys on `expires_at`). **Acceptable:** the search path filters `expires_at >= now` — 5y window satisfies that.
+
+**Step 2: Call from `captureMessage`**
+In `captureMessage`, after `const inserted = await messageStore.upsertMessageForCapture(messageRecord); if (!inserted) return;` and BEFORE the backlog branch, add:
+```ts
+if (!isBacklog && messageRecord.content) {
+  archiveMessageEmbedded(messageRecord);
+}
+```
+(`messageRecord` is the `MessageRecord` from `buildMessageRecord`; confirm it carries `content`, `channel_id`, `guild_id`, `created_at`. It does — see `messagesCrud`/`types`.)
+
+**Step 3: Type-check + lint**
+Run: `cd services/discord-gateway && pnpm typecheck && pnpm lint`
+Expected: PASS.
+
+**Step 4: Commit**
+```bash
+git add services/discord-gateway/src/modules/message-capture/archiveEmbedder.ts \
+        services/discord-gateway/src/modules/message-capture/messageCapture.ts
+git commit -m "feat(archive): embed captured messages into persistent Qdrant archive"
+```
+
+---
+
+## TASK 6 — Backend: `messages.semanticSearch` oRPC
+
+**Objective:** Public, read-only semantic search over the message archive.
+
+**Files:**
+- Modify: `services/backend/src/modules/messages/messages.repository.ts` — add `semanticSearch(query, limit, guildId?)`.
+- Modify: `services/backend/src/modules/messages/messages.service.ts` — expose `semanticSearch`.
+- Modify: `services/backend/src/orpc/router.ts` — add `messages.semanticSearch` procedure.
+- Create (or reuse): an embedding call from the backend. The backend does NOT import the gateway's `embeddingClient`. **Decision:** add a minimal backend embed helper `services/backend/src/modules/messages/embed.ts` that calls the same OpenAI-compatible endpoint via `config` (reuse `config.AI_LLM_BASE_URL`/`AI_LLM_API_KEY`/`AI_LLM_EMBEDDING_MODEL` if present on the backend; if not configured, return a clear "search unavailable" error). Mirror `encoding_format: "float"`.
+- Modify: `services/backend/src/modules/messages/messages.schema.ts` — add `semanticSearchQuery` zod schema (limit, guildId?, query).
+
+**Step 1: Backend embed helper** (`embed.ts`)
+```ts
+import OpenAI from "openai";
+import { config } from "@/shared/config/index";
+import { createChildLogger } from "@/shared/logger/index";
+const log = createChildLogger("messages-embed");
+let client: OpenAI | null = null;
+function getClient() {
+  if (!config.AI_LLM_API_KEY || !config.AI_LLM_EMBEDDING_MODEL) return null;
+  if (!client) client = new OpenAI({ apiKey: config.AI_LLM_API_KEY, baseURL: config.AI_LLM_BASE_URL, maxRetries: 0, timeout: 30_000 });
+  return client;
+}
+export async function embedQuery(text: string): Promise<number[] | null> {
+  const c = getClient(); if (!c) return null;
+  try {
+    const r = await c.embeddings.create({ model: config.AI_LLM_EMBEDDING_MODEL as string, input: text, encoding_format: "float" });
+    return r.data[0].embedding;
+  } catch (e) { log.warn({ error: e instanceof Error ? e.message : String(e) }, "query embed failed"); return null; }
+}
+```
+
+**Step 2: Repository `semanticSearch`**
+```ts
+async semanticSearch(queryVector: number[], limit: number, guildId?: string) {
+  // Search archive collection, then join messages for text + channel.
+  const hits = await searchQdrantV2(ARCHIVE_COLLECTION, queryVector, limit, 0.6);
+  const ids = hits.map(h => h.cacheKey.replace("qdrant:", "")); // point id → we stored archive:<messageId>
+  // decode: qdrantPointId is a uint64; we need the original message id.
+  // SIMPLER: store message_id inside the payload too. → update archiveEmbedder payload to include `message_id`.
+  ...
+}
+```
+**REFINEMENT (important):** `qdrantPointId` is a hash, not reversible. So the archive payload MUST carry `message_id` (and `channel_id`, `guild_id`, `username`, `created_at`) so the backend can return full results without a reverse lookup. **Update `archiveEmbedder.ts` payload** to include those fields, and relax `QdrantVerdictPayload` (or create `QdrantArchivePayload`) to allow them. Then `semanticSearch` returns the payloads directly (already contain text + metadata) — no DB join needed, and it works even for deleted messages (archive keeps the text). Apply `guildId` filter client-side on the returned payloads.
+
+**Step 3: Service + router**
+`messages.service.ts`: `async semanticSearch(query: string, limit: number, guildId?: string)` → embed → `repository.semanticSearch`.
+`orpc/router.ts` under `messagesRouter`:
+```ts
+semanticSearch: os
+  .input(z.object({ query: z.string().min(1), limit: z.coerce.number().int().positive().max(50).default(10), guildId: z.string().optional() }))
+  .handler(async ({ input }) => {
+    const results = await messagesService.semanticSearch(input.query, input.limit, input.guildId);
+    return { results, nextCursor: null };
+  }),
+```
+
+**Step 4: Type-check + lint (backend)**
+Run: `cd services/backend && pnpm typecheck && pnpm lint`
+Expected: PASS.
+
+**Step 5: Commit**
+```bash
+git add services/backend/src/modules/messages/embed.ts \
+        services/backend/src/modules/messages/messages.repository.ts \
+        services/backend/src/modules/messages/messages.service.ts \

+```
+
+---
+
+## TASK 7 — Frontend: semantic search UI on `messages` view
+
+**Objective:** Public, read-only search box + results on the existing messages dashboard.
+
+**Files:**
+- Modify: `services/frontend/src/app/(dashboard)/messages/page.tsx` + `view.tsx` — add a search input (debounced) that calls a new `useMessagesSemanticSearch` hook → `messages.semanticSearch` oRPC, renders results as message cards (reuse `GlassPanel`/`Badge`/existing message row components).
+- Modify: `services/frontend/src/lib/types/message.ts` — add `SemanticSearchResult` + `SemanticSearchResponse` types.
+- Modify: `services/frontend/src/lib/api/client.ts` (or `server.ts`) — add `semanticSearch` fetcher/routers export if using oRPC client; if the FE uses raw fetch through the proxy, add a `POST /api/messages/semantic-search` or an oRPC client call consistent with existing `messages.*` calls (follow the EXISTING pattern in `src/lib/api/` — inspect how `messages.list` is called and replicate).
+
+**Step 1: Add FE types**
+```ts
+export interface SemanticSearchResult {
+  message_id: string;
+  content: string;
+  username: string;
+  channel_id: string;
+  guild_id: string;
+  created_at: number;
+  score: number;
+}
+export interface SemanticSearchResponse { results: SemanticSearchResult[]; nextCursor: string | null; }
+```
+
+**Step 2: Add hook + wire view**
+Follow the existing `use-moderation.ts` SWR pattern. Add `useMessagesSemanticSearch(query, guildId?)` returning `{ data, isLoading, error }`. In `messages/view.tsx`, add a search `Input` (from `@/components/primitives`) at the top, debounce ~300ms, and render results below the live list when a query is present. Reuse the message-row rendering already in that view (do not invent a new component).
+
+**Step 3: Type-check + lint (frontend)**
+Run: `cd services/frontend && pnpm typecheck && pnpm lint`
+Expected: PASS.
+
+**Step 4: Commit**
+```bash
+git add services/frontend/src/app/\(dashboard\)/messages/ \
+        services/frontend/src/lib/types/message.ts \
+        services/frontend/src/lib/api/ \
+        services/frontend/src/hooks/
+git commit -m "feat(web): public semantic message search UI"

+
+## TASK 8 — Build all services + deploy + verify
+
+1. `cd services/discord-gateway && pnpm typecheck && pnpm build && pnpm lint`
+2. `cd services/backend && pnpm typecheck && pnpm build && pnpm lint`
+3. `cd services/frontend && pnpm typecheck && pnpm build && pnpm lint`
+4. Commit any formatting fixes (biome `--unsafe` if import order), author `asepharyana`, NO Co-Authored-By.
+5. `git push origin main` → watch `gh run watch` on "Build & Deploy (Nix)".
+6. After deploy: verify `systemctl show gmw-discord-gateway.service --property=ActiveEnterTimestamp,SubState` reflects new timestamp; same for backend + frontend.
+7. Smoke: `curl -s http://127.0.0.1:4001/trpc/messages.semanticSearch?input=<urlencoded json>` OR via the public web `imphnen.asepharyana.my.id` messages page → type a query → expect results (after some messages have been embedded; embeddings only run on NEW captures post-deploy, so seed a few test messages or backfill).
+8. Moderation explainability: trigger/observe a flagged message → confirm `moderation_actions.flags` is populated (SQL `SELECT flags, severity FROM moderation_actions ORDER BY created_at DESC LIMIT 5;`) and the public moderation view shows badges.
+
+---
+
+## RISKS / TRADEOFFS / OPEN QUESTIONS
+- **Embedding cost:** #3 embeds EVERY captured message → more embedding API calls. Mitigated: only text ≥3 chars, fire-and-forget, skip if model unconfigured. If cost is a concern, batch embed (reuse `embedTexts`) per capture burst — but start simple (per-message) and observe.
+- **Backfill:** post-deploy, the archive is empty until new messages arrive. Optional follow-up: a one-off backfill script over existing `messages` (out of scope for this plan unless user asks).
+- **Schema duplication:** the `pgModerationActionsTable` double-definition must stay in sync (Task 1 patches both). If `messages.ts` copy is provably dead, a follow-up can delete it — but NOT in this plan (avoid scope creep / risk).
+- **`AutoDeleteResult` verdict availability (Task 2):** requires confirming the `AnalysisResult` is reachable at the `createModerationAction` call sites. If not, we add an optional field to `AutoDeleteResult` at the orchestrator call site. This is the highest-risk integration point — verify before assuming.
+- **Public exposure:** semantic search returns message text + usernames. This is INTENDED (web is public for users). No auth added. If a guild wants private, that is a future config (out of scope).
+- **Qdrant payload type:** reusing `QdrantVerdictPayload` for archive is slightly awkward (carries `flags`/`expires_at` semantics). Cleaner: introduce `QdrantArchivePayload` with `message_id`, `channel_id`, `guild_id`, `username`, `content`, `created_at`, `expires_at`. **Prefer the dedicated payload type in Task 4/5** to avoid confusion.
+
+## VERIFICATION CHECKLIST
+- [ ] `moderation_actions` has 7 new columns (DB + both schema defs).
+- [ ] A real auto-delete populates `flags`/`severity`/`evidence` (verified via SQL).
+- [ ] Public moderation view renders badges + evidence (manual browser check on imphnen.asepharyana.my.id/moderation).
+- [ ] New message capture upserts a point into `gmw_message_archive` (verify via Qdrant `/collections/gmw_message_archive/points/count`).
+- [ ] `messages.semanticSearch` returns relevant results for a known phrase.
+- [ ] All three services: typecheck + build + lint green; CI "Build & Deploy (Nix)" green; systemd timestamps updated.

+> Hard constraint (user 2026-08-18): public read-only web, fully automatic,

+
+## 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

+# 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).
+

+
+## 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.

+- Kalau tool balas error atau kosong, bilang aja data lagi ga ketemu, jangan karang.

-- Kalo ga tau atau ga nyambung, bilang aja terus tanya balik biar ngobrolnya jalan

-## Architecture Patterns
+## AI moderation pipeline (`ai-moderation/`)
 
-### Modular MVC Structure
-Each module follows Controller-Service-Repository pattern:
-- **Controller**: Discord event listeners (messageCapture, aiAnalyzer, voiceController)
-- **Service**: Business logic (messageStore, llmModerationClient, recorder)
-- **Repository**: Data access (messageStore, voiceRecordingRepo)
+LLM-only judge — no regex/heuristic classification. One orchestrator call
+handles a whole batch (text + media split internally, parallel paths).
 
-### Event-Driven Design
-- **Redis Pub/Sub**: All events published to Redis channels
-- **Event Channels**:
-  - `discord:message:created` — New message captured
-  - `discord:message:updated` — Message edited
-  - `discord:message:deleted` — Message deleted
-  - `discord:message:analyzed` — AI analysis complete
-  - `discord:attachment:created` — Attachment detected
-  - `discord:attachment:uploaded` — Attachment uploaded to storage
-  - `discord:voice:started` — Voice recording started
-  - `discord:voice:stopped` — Voice recording stopped
-  - `discord:voice:uploaded` — Voice segment uploaded
-  - `discord:analysis:queue_status` — Analysis queue status update
+- `aiAnalyzer.ts` — public API: `queueMessageAnalysis`, `getAnalysisQueueStatus`,
+  `startPendingAIAnalysisWorker` (recovery worker + cache-prune).
+- `batchScheduler.ts` — per-conversation debounce → `processBatch`.
+- `batchProcessor.ts` — batch lock/circuit-breaker, fans failed targets to
+  individual fallback.
+- `individualFallbackProcessor.ts` — one-message-at-a-time retry path, own CB.
+- `conversationState.ts` / `circuitBreaker.ts` — per-conversation state,
+  Piscina `workerPool`, `getConversationKey`.
+- `ai-analysis-worker.ts` — Piscina entry point (`batch` / `individual` jobs).
+  Runs `runModerationAnalysis` off the main thread.
+- `moderationOrchestrator.ts` — exact-hash cache → batched semantic (Qdrant)
+  cache → LLM. Text and media paths run in parallel.
+- `textBatchProcessor.ts` / `mediaBatchProcessor.ts` — actual LLM calls
+  (one call per sub-batch, not per message).
+- `llmClient.ts` — central OpenAI-compatible chat client (streaming, retries,
+  thinking-disable injection). `visionAnalyzer.ts` / `mediaAnalysisClient.ts`
+  share the same router/base URL (different model alias for vision).
+- `embeddingClient.ts` + `qdrantClient.ts` — semantic cache (one embed call +
+  one batched Qdrant search for all uncached targets).
+- `textCacheStore.ts` / `channelCultureStore.ts` / `userProfileStore.ts` /
+  `userProfileStore.ts` — caches learned user profile summaries (optional).
 
-### Shared Infrastructure
-- **Config**: Zod-validated environment variables
-- **Logger**: Winston logger with context support
-- **Database**: Drizzle ORM with PostgreSQL
-- **Errors**: Custom error classes with codes and status codes
-- **Utils**: Retry logic with exponential backoff
+### Concurrency model
 
-### No HTTP Server
-- Discord Gateway service is **event-driven only**
-- No Express, WebSocket, or HTTP routes
-- All communication via Redis pub/sub
-- Backend service consumes events and serves HTTP API
+- Main thread owns the LLM semaphore (`AI_LLM_MAX_CONCURRENT`, default 5) via
+  `llmClient.withLlmConcurrency`.
+- Piscina pool (`PISCINA_MAX_THREADS`, default 4) runs the heavy LLM work off
+  the event loop; **each worker thread initializes its own pg Pool** (min 0,
+  grows to `POSTGRES_POOL_MAX`). See "Memory & connections" below.
 
-## Initialization Flow
+## Memory & DB connections
 
-1. Load environment config (Zod validation)
-2. Initialize database connection
-3. Run pending migrations
-4. Create Discord client with optimized cache settings
-5. Initialize Redis event broadcaster
-6. Register Discord event listeners (messageCapture, aiAnalyzer)
-7. Login to Discord
-8. Listen for graceful shutdown signals (SIGINT, SIGTERM)
+`MemoryMax=1G` (raised from 512M — live RSS sits at ~500 MiB, peak 508 MiB,
+so 512M left ~2% headroom and risked an OOM-kill restart). Host has 8 GB free.
 
-## Graceful Shutdown
+`POSTGRES_POOL_MIN=0` (default). The gateway = main process + up to 4 Piscina
+worker threads, each with its own pg Pool. With min:0 the pools stay empty
+until a query runs and drop idle clients afterward, instead of holding
+`(1 main + 4 workers) × 2 = 10` permanently-open idle connections against
+PgBouncer. The pool still grows on demand up to `POSTGRES_POOL_MAX`.
 
-On shutdown signal:
-1. Close database connection
-2. Disconnect from voice channels
-3. Close Redis connection
-4. Destroy Discord client
-5. Exit process
+## Event channels (Redis pub/sub)
 
-## Dependencies
+`discord:message:{created,updated,deleted,analyzed}`,
+`discord:attachment:{created,uploaded}`,
+`discord:voice:{started,stopped,uploaded,active_user,pcm,analyzed}`,
+`discord:analysis:queue_status`,
+`discord:reaction:{added,removed}`,
+`discord:thread:{created,deleted,updated}`,
+`discord:channel_topic:updated`,
+`discord:presence:updated`,
+`discord:guild_member:{added,removed}`.
+See `src/shared/redis-channels.ts` for the canonical names.
 
-**Core Discord**:
-- discord.js-selfbot-v13
-- @discordjs/voice
-- @discordjs/opus
+## Initialization flow
 
-**Audio Processing**:
-- prism-media (Opus encoding/decoding)
-- opusscript (Opus fallback)
-- sharp (Image resizing)
+1. Validate env (Zod). Refuse to start if `AI_ANALYSIS_ENABLED` but no key.
+2. `AUTO_MIGRATE_ON_STARTUP` → run pending Drizzle migrations.
+3. `initializeDatabase()` (pg Pool, min 0).
+4. Create discord.js-selfbot-v13 client; register listeners on `ready`.
+5. Start `gmw-discord-gateway` metrics server (port `METRICS_PORT`, default 4016).
+6. `client.login(token)`.
 
-**Data & Config**:
-- drizzle-orm (ORM)
-- pg (PostgreSQL driver)
-- zod (Config validation)
-- ioredis (Redis client)
+## Graceful shutdown
 
-**Logging & Utilities**:
-- winston (Structured logging)
-- p-retry (Retry logic)
-- p-limit (Concurrency limiting)
-- piscina (Worker pool)
+`SIGINT`/`SIGTERM` (and uncaught transient stream errors: EPIPE / ECONNRESET /
+ERR_STREAM_DESTROYED / ERR_STREAM_WRITE_AFTER_END are treated as non-fatal):
+stop metrics → stop muxer → disconnect voice → close PCM WS → close Redis →
+close command handler → close DB → destroy client → exit.
 
-## Event Flow Example
+## Observability
 
-### Message Capture Flow
-1. Discord emits `messageCreate` event
-2. `messageCapture.ts` listener receives event
-3. Extract metadata (user, channel, content, timestamp)
-4. `messageStore.ts` inserts into database
-5. `eventBroadcaster.messageCreated()` publishes to Redis
-6. Backend service subscribes to `discord:message:created` channel
-7. Backend processes and stores in its own database
+Prometheus scrapes `127.0.0.1:4016/metrics` (`bete_*` prefix). Collectors run
+per-scrape and expose: process memory/uptime, and (when AI analysis is on) live
+pipeline gauges — `ai_analysis_queued_conversations`,
+`ai_analysis_active_batch_requests`, `ai_analysis_active_individual_requests`,
+`ai_analysis_individual_in_flight`, `ai_analysis_individual_circuit_breaker_active`,
+`ai_analysis_worker_threads`, `ai_analysis_worker_threads_active`.
 
-### Voice Recording Flow
-1. `voiceController.connect()` joins voice channel
-2. `recorder.ts` subscribes to user audio streams
-3. For each speaking user:
-   - Create audio stream subscription
-   - Decode Opus packets to PCM
-   - Rotate OGG segments (5s default)
-   - Collect user metadata
-4. On silence (3s):
-   - Finalize segment
-   - Create metadata JSON
-   - Upload segment to storage
-   - Publish `discord:voice:uploaded` event
-5. Backend service receives event and indexes recording
+## Key invariants (do not break)
 
-## No Breaking Changes
-
-- Original `src/` remains untouched for now
-- Discord Gateway is a **new service** in `services/discord-gateway/`
-- Can run alongside existing monolith during transition
-- Backend service will consume Redis events
-- Frontend continues to use Backend HTTP API
+- **LLM is the only judge.** Failed LLM → `status:"error"` + recovery retry.
+  Never reintroduce regex/heuristic content classification.
+- **Discord tokens are sanitized** (`discordTokens.ts`: `<:emoji:id>` →
+  `[emoji:name]`, `<@id>` → `@user`, etc.) before content reaches the LLM, so
+  numeric snowflake IDs never trigger false positives.
+- **Semantic cache is batched** (one embed call + one Qdrant batch search),
+  not N sequential round-trips. `ensureQdrantCollection` is memoized.
+- **Streaming is mandatory** against the 9router base URL (non-stream waits for
+  the full body and times out). `llmClient` aggregates SSE chunks.

-## Module Responsibilities
+## Module responsibilities (summary)
 
 ### message-capture
-**Purpose**: Capture Discord messages (create, update, delete)
-**Pattern**: Controller-Service-Repository
-- **Controller** (messageCapture.ts): Listens to Discord events
-- **Service** (messageMetadata.ts): Extracts metadata
-- **Repository** (messageStore.ts): Database operations
-- **Events Published**:
-  - `discord:message:created`
-  - `discord:message:updated`
-  - `discord:message:deleted`
+Captures `messageCreate`/`messageUpdate`/`messageDelete`, extracts metadata,
+stores to Postgres, publishes to Redis. Controller–Service–Repository split:
+`messageCapture.ts` (listener) → `messageStore.ts` (DB) + `messageMetadata.ts`
+(service).
 
 ### ai-moderation
-**Purpose**: Analyze messages with LLM for moderation
-**Pattern**: Controller-Service-Service-Service
-- **Controller** (aiAnalyzer.ts): Orchestrates analysis workflow
-- **Service** (llmModerationClient.ts): LLM API integration
-- **Service** (aiAnalysisWorker.ts): Worker pool management
-- **Service** (indonesianTextNormalizer.ts): Text preprocessing
-- **Service** (moderationPrompt.ts): Prompt generation
-- **Events Published**:
-  - `discord:message:analyzed`
-  - `discord:analysis:queue_status`
+LLM-only moderation. Entry: `aiAnalyzer.ts` (`queueMessageAnalysis`,
+`startPendingAIAnalysisWorker`, `getAnalysisQueueStatus`). Scheduling:
+`batchScheduler.ts` → `batchProcessor.ts` (batch lock + circuit breaker) →
+`individualFallbackProcessor.ts` (per-message retry). Heavy work runs in the
+Piscina pool via `ai-analysis-worker.ts` (jobs `batch` / `individual`).
+Orchestration/caching: `moderationOrchestrator.ts` (exact hash → batched
+semantic Qdrant → LLM), `textBatchProcessor.ts` / `mediaBatchProcessor.ts`
+(one LLM call per sub-batch), `llmClient.ts` (central streaming client),
+`embeddingClient.ts` + `qdrantClient.ts` (semantic cache), plus
+`channelCultureStore.ts` / `userProfileStore.ts`.
 
 ### voice-recording
-**Purpose**: Record voice channel audio
-**Pattern**: Controller-Service-SubServices
-- **Controller** (voiceController.ts): Voice connection management
-- **Service** (recorder.ts): Recording orchestration
-- **Sub-services** (recorder/*): Audio processing pipeline
-  - audioStream.ts: Opus packet subscription
-  - decoder.ts: Opus to PCM decoding
-  - segment.ts: OGG file rotation
-  - metadata.ts: User metadata collection
-  - sessionRecording.ts: Session lifecycle
-  - uploader.ts: Segment upload
-- **Events Published**:
-  - `discord:voice:started`
-  - `discord:voice:stopped`
-  - `discord:voice:uploaded`
+`voiceController.ts` (connect/disconnect/list) + `recorder.ts` (orchestration)
++ `recorder/` (decoder, segment, session, uploader, oggCrc). Publishes
+`discord:voice:*` events. Real-time audio also streamed via `voice-pcm-ws`.
 
 ### attachment-upload
-**Purpose**: Upload message attachments to external storage
-**Pattern**: Service-Service
-- **Service** (attachmentUploader.ts): Upload orchestration
-- **Service** (imageResizer.ts): Image processing
-- **Events Published**:
-  - `discord:attachment:created`
-  - `discord:attachment:uploaded`
+`attachmentUploader.ts` (download → upload to storage) + `imageResizer.ts`
+(sharp resize). Emits `discord:attachment:*`.
 
 ### event-broadcaster
-**Purpose**: Publish events to Redis pub/sub
-**Pattern**: Service-Domain
-- **Service** (eventBroadcaster.ts): Redis publisher
-- **Domain** (eventTypes.ts): Event type definitions
-- **Channels**:
-  - discord:message:* (message events)
-  - discord:attachment:* (attachment events)
-  - discord:voice:* (voice events)
-  - discord:analysis:* (analysis events)
+`RedisEventPublisher` (ioredis publish) + `EventBroadcaster` (typed methods).
+Channel names in `src/shared/redis-channels.ts`.
 
-## Shared Infrastructure
+### gateway-metrics
+`metrics.ts` Prometheus HTTP server on `METRICS_PORT` (4016). Collectors run
+per scrape; live pipeline gauges registered in `bootstrap.ts`.
 
-### config
-- Zod-validated environment variables
-- Type-safe configuration access
-- Sensible defaults
+## Shared infrastructure
+- **config** — Zod schema in `shared/config/index.ts` (single source of truth).
+- **database** — Drizzle ORM over `pg`; pool `min:0` (`shared/config`).
+- **logger** — `pino` wrapper, `createChildLogger()` for context loggers.
+- **errors** — `AppError` hierarchy (`ConfigError`, `AudioError`, …).
 
-### database
-- Drizzle ORM schema
-- PostgreSQL connection
-- Migration management
-- Voice recording repository
-
-### logger
-- Winston logger wrapper
-- Context-aware logging
-- Log serialization utilities
-
-### errors
-- Custom error classes
-- Error codes and HTTP status codes
-- Proper error hierarchy
-
-### utils
-- Retry with exponential backoff
-- Configurable retry parameters
-
-### discord
-- Discord.js client configuration
-- Cache optimization
-- Partial handling

-## Summary
-
-The Discord Gateway service is a **pure event-driven microservice** that:
-- Captures Discord messages, voice, and attachments
-- Performs AI moderation analysis
-- Publishes events to Redis pub/sub
-- Has no HTTP server or WebSocket
-- Follows Modular MVC pattern
-- Maintains clean module boundaries
-- Provides type-safe configuration
-- Includes structured logging
-- Handles graceful shutdown
-
-The service is designed to run alongside the Backend service, which consumes Redis events and serves the HTTP API to the Frontend.
+## Notes
+- No HTTP server (other than the metrics endpoint). Pure event-driven.
+- `MODULE_STRUCTURE.md` is intentionally a sketch; `ARCHITECTURE.md` is the
+  detailed reference. When they diverge, `ARCHITECTURE.md` wins.

+ * Per-word "kamus" enrichment for LLM moderation.
+ *
+ * Problem: the moderation LLM often meets words it does not know — regional
+ * slang (Jawa/Sunda), foreign terms, niche anime/game jargon, or obscure
+ * technical vocabulary. When it guesses, it either invents a wrong meaning
+ * (false positive on a safe word) or misses a violation hidden in unfamiliar
+ * wording (false negative on an unknown vulgar/slang term).
+ *
+ * Solution: extract candidate "unknown-looking" words from message content,
+ * look each one up on Wikipedia via the Wikipedia REST/Action APIs, and inject
+ * the definitions into the LLM prompt as a `<term_glossary>` block so verdicts
+ * are based on facts instead of guesses.
+ *
+ * Cost control & persistence:
+ *  - successfully resolved definitions are PERSISTED PERMANENTLY in Postgres
+ *    (`term_glossary_cache`) — definitions rarely change, so a resolved term
+ *    is never searched again; only misses stay ephemeral (Redis/LRU, 1h);
+ *  - in-memory LRU + Redis (shared cache store) sit in front of
+ *    the DB as fast read caches, so repeat lookups are effectively free;
+ *  - lookups per batch are bounded (AI_GLOSSARY_MAX_TERMS);
+ *  - live Wikipedia calls are rate-limit aware: concurrency 2 + stagger, retry
+ *    once on empty results, and misses cached for only 1h so a limiter/
+ *    network blip is not treated as a permanent miss;
+ *  - only results that read like actual definitions are accepted (Wikipedia
+ *    preferred; disambiguation/ads/translate-homepages rejected);
+ *  - everything degrades gracefully: no Redis, no SearXNG, no match
+ *    → the block is simply omitted and moderation proceeds as before.
