feat(gmw): moderation explainability + semantic message search

- Persist structured verdict (flags/severity/confidence/evidence) on
  moderation_actions so the public web can show WHY a message was moderated.
- Add a persistent Qdrant archive collection (gmw_message_archive); embed
  every captured message at capture time (fire-and-forget, best-effort).
- Public semantic search over the archive (backend oRPC + FE toggle on the
  messages view). Both features are read-only/public and fully automatic.

+# 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).** Line truncated
+- 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 leLine truncated
+- **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)` / `searchQLine truncated
+- 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?: AnalysisResulLine truncated
+
+**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.
+
+**Step 6: Commit**
+```bash
+git add services/discord-gateway/src/modules/ai-moderation/verdictToActionFields.ts \
+        services/discord-gateway/src/modules/ai-moderation/autoDeleteManager.ts \
+        services/discord-gateway/src/modules/command-handler/moderation.handler.ts
+git commit -m "feat(mods): persist structured verdict into moderation_actions"
+```
+
+---
+
+## 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
+git commit -m "feat(web): surface moderation explainability (flags/severity/evidence)"
+```
+
+---
+
+## 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, anLine truncated
+
+**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

+## 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.
