+- Satu sumber kebenaran: semua data berasal dari `@mcpedia/core` types & `@mcpedia/config` section presets; tidak ada shape duplikat di FE.
+- Selaras dengan gateway/BE data flow: tRPC `apps/api` (`/trpc/*`) + REST `/api/*` + MCP `:4021` semua mengembalikan shape yang sama (DocumentMeta, SectionInfo, SearchHit, ExportData).
+- Ganti pola fetch ad-hoc (`fetch("/api/...")` tersebar) dengan **SWR** terpusat — cache, revalidate, mutate, optimistic UI, error boundary konsisten.
+- Hapus sisa TanStack (saat ini tidak ada deps TanStack — audit `apps/web/package.json` clean; tapi pola akan dibakukan supaya tidak masuk lagi).
+- UI: Archival Precision tetap (monochrome, hairline, mono telemetry), tapi lebih live dan terisi data real (bukan placeholder).
+
+## 2. Audit Status Quo
+
+### FE sekarang
+- Next.js 16.3.4, App Router, `force-dynamic` di semua page yang baca DB.
+- RSC langsung import `@mcpedia/core` (`listDocuments`, `getDocument`, `listSections`, `getRelated`, `listRevisions`, `getExportDocuments`). SEO bagus, tapi client components (Sidebar, Header, Search, CommandMenu) fetch ulang via REST tanpa cache sharing.
+- REST: `/api/search?q&mode&limit`, `/api/docs` (list), `/api/sections`, `/api/export?path&sort`, `/api/revisions/restore`, `/api/auth/login`.
+- tRPC `apps/api` (Hono) expose: search/semanticSearch/hybridSearch, getDocument, listDocuments, sections, related, revisions, CRUD (gated `x-webhook-secret`), jobStatus, reindex hooks, `/health`, `/metrics`.
+- MCP `:4021` Streamable HTTP `/mcp` expose 13 tools (tidak dipakai FE, tapi shape-nya sama).
+- Tidak ada `swr` / `@tanstack/react-query` di `apps/web/package.json` — jadi migrasi = greenfield SWR layer, bukan replace.
+- Design tokens sudah rapi di `globals.css` (CSS vars light/dark + `--brand`, `--bg-*`, `--text-*`, `--code-*`). Header/Sidebar/Markdown/TOC/DocActions sudah pakai tokens.
+
+### Masalah yang diselesaikan redesign
+1. Sidebar & Header fetch `/api/docs` + `/api/sections` tanpa deduplikasi — tiap navigasi fetch ulang, tidak ada stale-while-revalidate.
+2. Search page client-side `fetch` manual tanpa debounce terpusat, tanpa cache antar-mode (hybrid/keyword/semantic saling overwrite).
+3. Doc page RSC tidak live: setelah create/update/delete atau reindex, harus hard refresh. Tidak ada `mutate` cross-component.
+4. Shape drift: Search `snippet` vs `SearchHit` vs `ChunkHit` tidak konsisten antara `/api/search` dan `@mcpedia/search` — perlu typed fetcher.
+5. Tidak ada surface untuk queue/embeddings status (BE punya `jobStatus`, `queueStatus`, `INDEX_QUEUE` BullMQ) — FE buta terhadap indexing.
+
+## 3. Arsitektur Target
+
+```
+apps/web/app/
+  lib/
+    fetcher.ts          — typed fetcher (fetch JSON + error envelope)
+    swr.ts              — SWRConfig global (dedupingInterval, focusThrottle, errorRetry)
+    api.ts              — typed client untuk /api/* (listDocuments, search, sections, export, revisions)
+  hooks/
+    useSections.ts      — SWR '/api/sections' -> SectionInfo[]
+    useDocuments.ts     — SWR '/api/docs?section&status' -> DocumentMeta[]
+    useDocument.ts      — SWR '/api/docs/:slug' (baru, GET single) -> Document
+    useSearch.ts        — SWR key [q, mode, limit] -> SearchHit[] + debounced
+    useRelated.ts       — SWR '/api/related?slug'
+    useRevisions.ts     — SWR '/api/revisions?slug'
+    useQueueStatus.ts   — SWR '/api/queue/status' poll 5s (opsional, admin only)
+  components/
+    (existing: Header, Sidebar, CommandMenu, Markdown, TOC, DocActions, ...)
+    SearchBar.tsx       — reusable, dipakai Header + Search page + CommandMenu
+    SectionCard.tsx     — extract dari page.tsx
+    DocumentCard.tsx    — reusable card (recent, related, folder list)
+    TagCloud.tsx        — baru: agregasi tags dari docs
+    QueueBadge.tsx      — baru: show indexing status (waiting/active/failed)
+    EmptyState.tsx / ErrorState.tsx
+  app/
+    layout.tsx          — tambah <SWRProvider> wrapper (client boundary)
+    page.tsx            — refactor: RSC shell + client islands via SWR
+    [section]/page.tsx  — sama
+    [section]/[...slug]/page.tsx — RSC hero + Markdown, client islands (related/revisions via SWR)
+    search/page.tsx     — fully SWR, hapus useState fetch manual
+    create/page.tsx     — mutate after create
+    dashboard/page.tsx  — BARU (optional phase 2): queue, sections, recent, tag stats
+```
+
+### Prinsip SWR
+- Satu `fetcher` generic: `fetcher<T>(url: string): Promise<T>` — throw on !ok dengan `info` + `status` untuk error boundary.
+- `SWRConfig` di `layout.tsx` client wrapper: `dedupingInterval: 4000`, `focusThrottleInterval: 10000`, `shouldRetryOnError: false` untuk search, `refreshInterval` hanya untuk queue.
+- Semua hooks pakai key array/string yang deterministic supaya `mutate` cross-page bisa: `mutate('/api/docs')`, `mutate('/api/sections')`.
+- Debounce search di hook, bukan di component: `useDebouncedValue(q, 180ms)` internal ke `useSearch`.
+- Optimistic mutate untuk create/update/delete: `mutate('/api/docs', optimisticList, false)` lalu revalidate.
+
+## 4. Kontrak Data (FE ↔ BE)
+
+Semua types import dari `@mcpedia/types` — tidak ada re-declare shape di FE.
+
+| FE Hook | BE Source | Endpoint | Shape |
+|---------|-----------|----------|-------|
+| useSections | `listSections()` | `GET /api/sections` | `SectionInfo[]` |
+| useDocuments | `listDocuments({section,status})` | `GET /api/docs?section=&status=` | `DocumentMeta[]` |
+| useDocument | `getDocument(slug)` | `GET /api/docs/:slug` (baru) | `Document` |
+| useSearch | `keywordSearch/hybridSearch/semanticSearch` | `GET /api/search?q&mode&limit` | `{results: {slug,title,section,score,snippet}[]}` |
+| useRelated | `getRelated(slug)` | `GET /api/related?slug=` (baru, atau reuse via core) | `DocumentMeta[]` |
+| useRevisions | `listRevisions(slug)` | `GET /api/revisions?slug=` (baru) | `Revision[]` |
+| useQueueStatus | BullMQ `getQueue()` | `GET /api/queue/status` (baru, proxy ke apps/api /metrics atau queue) | `{waiting,active,completed,failed,delayed}` |
+
+**Tambahan endpoint yang perlu dibuat (tipis, proxy ke core):**
+- `GET /api/docs/[slug]` — single doc (hindari RSC-only fetch, enable SWR).
+- `GET /api/related?slug=&limit=` — wrapper `getRelated`.
+- `GET /api/revisions?slug=&limit=` — wrapper `listRevisions`.
+- `GET /api/queue/status` — wrapper `getQueue().get*Count()` (admin-only atau public read-only).
+- (Opsional) `GET /api/tags` — agregasi tags dari `listDocuments` untuk TagCloud.
+
+Semua endpoint return envelope sama: `{data}` atau `{results}` + `{error}` on 500, dengan `Content-Type: application/json`. Auth untuk mutasi tetap `x-webhook-secret` atau cookie `mcpedia_admin`.
+
+## 5. Perubahan Per-File (Rincian)
+
+### Phase 0 — Foundation (wajib)
+- `apps/web/package.json`: tambah `swr: ^2.3.x` (latest 2.x). Tidak tambah TanStack. `bun install` + cek `typecheck`.
+- `apps/web/app/lib/fetcher.ts` (baru): `export const fetcher = <T>(url: string): Promise<T> => fetch(url).then(r => { if(!r.ok) throw ...; return r.json() })`
+- `apps/web/app/lib/swr.tsx` (baru): `SWRProvider` client component wrapping `SWRConfig`.
+- `apps/web/app/lib/api.ts` (baru): typed helpers `searchDocs(q,mode,limit)`, `listDocs()`, `listSections()` — dipakai hooks.
+- `apps/web/app/layout.tsx`: bungkus children dengan `<SWRProvider>` (client boundary minimal).
+
+### Phase 1 — Hooks + Refactor Existing Pages
+- `hooks/useSections.ts`, `useDocuments.ts`, `useSearch.ts`: ganti `useEffect+fetch` di `Header.tsx`, `Sidebar.tsx`, `search/page.tsx`, `CommandMenu.tsx`, `page.tsx` (home).
+- `Header.tsx`: `useSections()` alih-alih `useState+useEffect fetch /api/sections`.
+- `Sidebar.tsx`: `useDocuments()` + `useSections()` + filter memo — hilangkan `useEffect fetch /api/docs`.
+- `search/page.tsx`: `useSearch(q, mode)` — hapus `handleSearch` manual, pakai `isLoading`, `isValidating`, `error` dari SWR. Mode & section filter tetap local state, tapi key SWR mencakup keduanya.
+- `CommandMenu.tsx`: `useSearch(query)` debounced — hapus timer manual.
+- `app/page.tsx`: tetap RSC untuk SEO (listDocuments/listSections server), tapi `SectionTree` dan `Recently Updated` bisa jadi client islands yang pakai SWR untuk live update (opsional: keep RSC + `mutate` on focus).
+- `[section]/page.tsx` & `[section]/[...slug]/page.tsx`: RSC hero + Markdown tetap, `related` & `revisions` pindah ke client islands `RelatedGrid` & `RevisionList` pakai `useRelated`/`useRevisions`.
+
+### Phase 2 — Fitur Baru (detail)
+1. **Dashboard `/dashboard` (baru, admin-aware):**
+   - Cards: total docs, sections, queue (waiting/active/failed), embedding provider status.
+   - Section breakdown bar (docCount per section).
+   - Tag cloud (top 20 tags dengan count).
+   - Recent activity (last 10 updated docs).
+   - Queue status poll 5s via `useQueueStatus` (hanya jika admin cookie ada, else hide).
+2. **Tag Explorer `/tags` atau sidebar widget:**
+   - `GET /api/tags` agregasi, klik tag → `/search?tag=...` atau filter docs.
+3. **Doc page enhancements:**
+   - `QueueBadge` di hero jika doc sedang di-index (query queue by slug).
+   - Optimistic revision restore: `mutate('/api/revisions?slug=...')` setelah POST restore.
+   - Related docs pakai SWR + `keepPreviousData`.
+4. **Search enhancements:**
+   - Persist `mode` di URL (`?q=&mode=hybrid`) — sudah ada, pertahankan + SWR key sync.
+   - Highlight snippet `mark` sudah ada — pertahankan.
+   - Empty & error states pakai `EmptyState`/`ErrorState` components.
+5. **Create/Edit:**
+   - Setelah `POST /api/docs`, `mutate('/api/docs')` + `mutate('/api/sections')` + `router.push('/${slug}')`.
+   - Custom fields (extraFields) tetap flat → `splitPayload` di BE tidak berubah.
+6. **Export:**
+   - `PdfExportView` tetap, tapi tambah SWR preload `getExportDocuments` untuk preview count sebelum export.
+
+### Phase 3 — Polish & Cleanup
+- Hapus semua `fetch` ad-hoc yang tersisa — semua lewat hooks.
+- Pastikan `globals.css` tokens dipakai konsisten (tidak ada hard-coded hex baru).
+- `CommandMenu` jadi satu-satunya omnisearch entry — `Header` search icon di mobile buka CommandMenu, bukan link `/search`.
+- A11y: `aria-live` untuk search results count, `role="status"` untuk queue badge.
+- Print/PDF styles sudah ada — tidak diubah.
+
+## 6. File yang Disentuh (Checklist)
+
+Baru:
+- `apps/web/app/lib/fetcher.ts`
+- `apps/web/app/lib/swr.tsx`
+- `apps/web/app/lib/api.ts`
+- `apps/web/app/hooks/useSections.ts`
+- `apps/web/app/hooks/useDocuments.ts`
+- `apps/web/app/hooks/useSearch.ts`
+- `apps/web/app/hooks/useRelated.ts`
+- `apps/web/app/hooks/useRevisions.ts`
+- `apps/web/app/hooks/useQueueStatus.ts`
+- `apps/web/app/hooks/useTags.ts` (opsional)
+- `apps/web/app/components/SearchBar.tsx`
+- `apps/web/app/components/SectionCard.tsx`
+- `apps/web/app/components/DocumentCard.tsx`
+- `apps/web/app/components/TagCloud.tsx`
+- `apps/web/app/components/QueueBadge.tsx`
+- `apps/web/app/components/EmptyState.tsx`
+- `apps/web/app/dashboard/page.tsx` (baru)
+- `apps/web/app/api/docs/[slug]/route.ts` (baru)
+- `apps/web/app/api/related/route.ts` (baru)
+- `apps/web/app/api/revisions/route.ts` (baru GET)
+- `apps/web/app/api/queue/status/route.ts` (baru)
+- `apps/web/app/api/tags/route.ts` (baru, opsional)
+
+Edit:
+- `apps/web/package.json` (+ swr)
+- `apps/web/app/layout.tsx` (+ SWRProvider)
+- `apps/web/app/page.tsx` (extract SectionCard, optional SWR islands)
+- `apps/web/app/[section]/page.tsx` (DocumentCard)
+- `apps/web/app/[section]/[...slug]/page.tsx` (related/revisions islands)
+- `apps/web/app/search/page.tsx` (full SWR)
+- `apps/web/app/components/Header.tsx` (useSections)
+- `apps/web/app/components/Sidebar.tsx` (useDocuments/useSections)
+- `apps/web/app/components/CommandMenu.tsx` (useSearch)
+- `apps/web/app/create/page.tsx` (mutate)
+- `apps/web/app/components/DocForm.tsx` (mutate setelah submit)
+
+Tidak disentuh:
+- `packages/core`, `packages/types`, `packages/config`, `packages/db` (hanya dibaca)
+- `apps/api`, `apps/mcp`, `apps/worker` (hanya diproxy)
+- `globals.css`, `next.config.ts`, `tailwind` config (kecuali perlu token baru)
+
+## 7. Urutan Implementasi
+
+1. Phase 0 foundation → `bun install && bun run typecheck` green.
+2. Phase 1 hooks + Header/Sidebar/Search/CommandMenu → manual test + `next build` smoke.
+3. Phase 2 doc page islands + create mutate → test CRUD flow dengan `x-webhook-secret` / admin cookie.
+4. Phase 2 dashboard + tags → behind `canEdit` guard jika perlu.
+5. Phase 3 cleanup, hapus fetch manual, final `bun run lint && typecheck && build`.
+
+## 8. Verifikasi
+
+- `bun run typecheck` — tidak ada error (SWR types + @mcpedia/types).
+- `bun run lint` — rules Next 16 ok.
+- `bun --cwd apps/web run build` — semua route `force-dynamic` OK, tidak ada import-time DB throw.
+- Manual:
+  - Sidebar filter + section count live setelah create doc.
+  - Search mode switch (hybrid/keyword/semantic) cache terpisah, tidak flicker.
+  - CommandMenu ⌘K debounce 180ms, Enter navigasi benar.
+  - Doc related & revisions muncul via SWR tanpa hard refresh.
+  - Queue badge (jika ada) poll 5s, tidak spam (dedupingInterval).
+  - Dark/light toggle tetap work (SWRProvider tidak break `ThemeToggle`).
+- Staging: `curl /api/search?q=test&mode=hybrid`, `/api/sections`, `/api/docs` return shape konsisten dengan tRPC.
+
+## 9. Risiko & Mitigasi
+
+- RSC + SWR double fetch: mitigasi dengan `fallbackData` dari RSC props ke SWR hook di islands (opsi, tidak wajib v1).
+- Peningkatan request ke DB: SWR deduping 4s + `revalidateOnFocus: false` untuk search, `true` untuk sections/docs.
+- Auth untuk `/api/queue/status`: jadikan public read-only (hanya counts, bukan detail job) — aman.
+
+## 10. Keputusan yang Perlu Kamu Konfirmasi
+
+1. **Dashboard `/dashboard` perlu tidak?** Atau cukup queue badge di existing pages? Rekomendasi: bikin, tapi Phase 2 — bisa ditunda.
+2. **Endpoint baru (`/api/docs/[slug]`, `/api/related`, `/api/revisions` GET, `/api/queue/status`, `/api/tags`) setuju?** Alternatif: FE langsung pakai tRPC client (`@trpc/client`) — tapi spec ini pilih REST `/api/*` supaya Next cache & SWR fetcher simpel.
+3. **SWR vs tRPC+SWR?** Spec ini pakai SWR+REST (paling simpel, tidak tambah `@trpc/client` di FE). Jika mau tRPC, tambah `createTRPCClient` + `httpBatchLink` — tradeoff: lebih typed tapi lebih berat. Default: SWR+REST.
+4. **Keep RSC server fetch untuk SEO atau full client SWR?** Rekomendasi: keep RSC untuk initial HTML (SEO), SWR untuk live revalidation di client islands — hybrid, bukan full SWR.
+
+---
+
+Jawab: `Lanjut Phase 0+1` untuk eksekusi, atau beri koreksi poin 10.

+# MCPedia — Nix-based CI/CD Migration Plan
+
+## Goal
+Migrate from tarball+SSH deploy to Nix-native build-and-deploy (like GMW).
+CI builds with Nix in GitHub Actions → `nix copy` closure to VPS →
+`nix-env --set` + `systemctl restart` on VPS. VPS never builds.
+
+## Services to migrate
+| Service | Build | Runtime | systemd unit |
+|---------|-------|---------|-------------|
+| web (Next.js) | `bun run build` → `.next` | `next start` | `mcpedia-web` |
+| api (Hono) | `bun build src/index.ts` → `dist/index.js` | `bun run src/index.ts` | `mcpedia-api` |
+| mcp (MCP server) | `bun build src/http.ts` → `dist/http.js` | `bun run src/http.ts` | `mcpedia-mcp` |
+| worker (BullMQ) | `bun build src/index.ts` → `dist/index.js` | `bun run src/index.ts` | `mcpedia-worker` |
+
+## Changes
+
+### 1. flake.nix (new)
+- `nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable"` (Bun >=1.3)
+- 4 packages: `web`, `api`, `mcp`, `worker`
+- Each: `mkDerivation` with `bun` as nativeBuildInput, `sandbox=false`
+- Filter source to exclude `.next`, `node_modules`, `.git`
+
+### 2. CI workflow (.github/workflows/ci.yml — rewrite)
+- `test` job: typecheck + test (Bun, as before)
+- `build-and-deploy` job: matrix [web, api, mcp, worker]
+  - `DeterminateSystems/nix-installer-action@v16` with `determinate: false`, `sandbox=false`
+  - `DeterminateSystems/magic-nix-cache-action@v14` with `use-flakehub: false`
+  - `nix build .#<service>` → store path
+  - SSH setup (key sanitization)
+  - `nix copy --to ssh://...`
+  - `nix-env --profile /nix/var/nix/profiles/mcpedia-<service> --set <path>`
+  - `systemctl restart mcpedia-<service>`
+
+### 3. systemd units (update on VPS)
+- Change `ExecStart` from `bun run` to Nix profile binary path
+- Profile path: `/nix/var/nix/profiles/mcpedia-web/bin/mcpedia-web`
+- Keep `EnvironmentFile` pointing to `.env`
+- Keep `Restart=always`
+
+### 4. Deploy secrets
+- `SSH_PRIVATE_KEY` (already exists as `SSH_DEPLOY_KEY`)
+- `VPS_HOST`, `VPS_USER`, `VPS_SSH_PORT`
+
+## Verification
+- `nix build .#web --impure` builds
+- `gh run list` shows all 4 services `completed success`
+- `curl https://wiki.asepharyana.my.id/` returns 200
+- `journalctl -u mcpedia-web` shows Next.js started

+# Phase 15b — CI/CD: Build in CI, Deploy only on VPS
+
+> User: "alur ci nya juga benarkan lah masa build di vps,harusnya kan di vps hanya deploy, dan seharusnya pakai nix"
+
+## Final Architecture
+
+### CI Workflow (`.github/workflows/ci.yml`)
+Single workflow with two jobs:
+
+**Job 1: `build`** (runs on GitHub Actions runner)
+1. Checkout → Set up Bun 1.3.14 → `bun install --frozen-lockfile`
+2. Typecheck (`bun run typecheck`)
+3. Build web (`working-directory: apps/web && bun run build`) ← **Build happens here, not VPS**
+4. Upload `.next/` as artifact (`include-hidden-files: true` ← critical for hidden `.next/` dir)
+5. MCP smoke test (conditional on DATABASE_URL secret — skipped in CI without DB)
+6. Unit tests (`bun run test`)
+
+**Job 2: `deploy`** (needs: build, main branch only)
+1. Download artifact to `apps/web/.next`
+2. Tar `.next` (exclude cache, ~15MB tarball)
+3. SCP tarball to VPS (`/tmp/`)
+4. SSH to VPS: `git pull` → `bun install` → `bun run scripts/indexer.ts` → `tar -xzf` → `systemctl restart`
+
+### Key Fixes During This Phase
+
+1. **`actions/checkout@v4` → `@v5`** — Node 20 deprecation warning
+2. **`bun --cwd apps/web run build` → `working-directory: apps/web`** — `bun run` doesn't support `--cwd` flag; was silently printing usage, exiting 0
+3. **`path: apps/web/.next/`** → **`path: apps/web/.next`** + **`include-hidden-files: true`** — `.next/` is a hidden directory; `upload-artifact@v4` excludes hidden files by default
+4. **`bun --cwd apps/mcp run smoke`** → **`working-directory: apps/mcp`** — same `--cwd` bug
+5. **Smoke test made conditional** on `DATABASE_URL` — was silently failing (never actually ran due to bug #2/#4)
+6. **SCP of individual `.next/*`** → **tarball transfer** — SCP with glob of hidden files was failing/timing out
+7. **Deploy tarball excludes `.next/cache`** — cache is ephemeral, reduces transfer size
+8. **Merged ci.yml + deploy.yml** into single workflow — `workflow_run` trigger can't access artifacts from CI run

+# SSH deploy to bun-source services (not Nix): gotchas
+
+This repo (`asepharyana/mcpedia`) deploys **bun source** via systemd — NOT via
+Nix like GMW. The pattern is: CI builds in GitHub Actions → upload artifact →
+deploy job downloads artifact → SCP tarball to VPS → SSH → git pull + unpack +
+index + `systemctl restart`. The VPS does NOT build.
+
+## Gotchas (learned during mcpedia deploy setup, 2026-08-20/21)
+
+### 1. SSH host = public IP, NOT Tailscale IP
+
+The VPS appears in `~/.ssh/config` as `Host orange → HostName 100.79.111.61`.
+That IP is a **Tailscale `tailscale0` interface address** in the CGNAT range
+(`100.64.0.0/10`). GitHub Actions runners are NOT on the Tailscale network, so
+they get `Connection timed out` (dropped at the network layer, not refused).
+
+**Fix:** Use the VPS's real public IP (`45.127.35.244`, discovered via
+`curl https://api.ipify.org` from the VPS). Port 22 is open in iptables
+(`ACCEPT tcp dpt:22` from `0.0.0.0/0`).
+
+### 2. SSH key MUST be stored directly from file (not shell variable)
+
+Storing the deploy key via a shell variable corrupts it:
+
+```bash
+# ❌ WRONG — newlines get mangled by the shell → "ssh: no key found"
+PRIV_KEY=$(cat keyfile)
+gh secret set SSH_DEPLOY_KEY --body "$PRIV_KEY"
+
+# ✅ CORRECT — pipe the file directly so GitHub preserves all bytes
+cat keyfile | gh secret set SSH_DEPLOY_KEY --repo asepharyana/mcpedia
+```
+
+Symptom: `appleboy/ssh-action` fails with
+`ssh.ParsePrivateKey: ssh: no key found`.
+
+### 3. Use `appleboy/ssh-action@v1` (not `@v1.1.0`)
+
+- `@v1.1.0` (very old) has a key-parsing bug that rejects valid keys
+  (`ssh.ParsePrivateKey: ssh: no key found`).
+- `@v1` (latest) handles OpenSSH ed25519 keys correctly.
+
+### 4. `appleboy/ssh-action` needs explicit `envs` to pass through secret-derived vars
+
+The `envs` parameter passes environment variables to the remote script.
+Include any secret you reference in the script:
+```yaml
+envs: SSH_DEPLOY_HOST  # passes SSH_DEPLOY_HOST into the remote script
+```
+Without it, `echo $SSH_DEPLOY_HOST` on the VPS returns empty even though the
+action connected.
+
+### 5. Always pass `-o IdentitiesOnly=yes`
+
+Without it, SSH offers ALL loaded identities (deploy key + default keys) and the
+server may reject after "Too many authentication failures". `appleboy/ssh-action`
+handles this internally via the `key` input, but if you use raw `ssh` add
+`-o IdentitiesOnly=yes`.
+
+### 6. GitHub `workflow_run` does NOT carry the push commit SHA
+
+`workflow_run` events fire after CI completes, but `actions/checkout` checks out
+the **default branch tip**, not the specific commit. This is fine for deploy
+(the script does `git pull origin main` anyway), but verify the checkout ref
+matches what CI built if you rely on it.
+
+### 7. DB migrations: `db:push` prompt is non-interactive-unfriendly in SSH deploy
+
+When the schema includes a new column (e.g. adding `extra_fields JSONB`),
+`drizzle-kit push` in the SSH deploy script needs to be run. Two issues:
+
+- **`--strict` mode (config default)**: `drizzle.config.ts` has `strict: true`,
+  which makes `drizzle-kit push` prompt `No, abort / Yes, I want to execute all
+  statements`. In a non-interactive SSH script (no TTY), the prompt never receives
+  input and the command times out → SIGTERM → exit code 124 → deploy fails.
+  `set -e` then kills the whole deploy.
+- **`bun run <script>` ambiguity**: `bun run index` resolves the `index` script
+  from `package.json`. In a monorepo with workspace packages, ensure the script
+  name is unique or use the explicit file path (e.g. `bun run scripts/indexer.ts`).
+
+**Fix**: Use `psql` for schema changes instead of `db:push`:
+```bash
+psql "$DATABASE_URL" -c \
+  "ALTER TABLE documents ADD COLUMN IF NOT EXISTS extra_fields jsonb DEFAULT '{}'::jsonb NOT NULL;"
+```
+
+After deploy, check the **public URL** (not just `systemctl is-active`):
+```bash
+curl -sk -o /dev/null -w "%{http_code}" https://wiki.asepharyana.my.id/
+curl -s https://wiki.asepharyana.my.id/docs/websocket/contract | grep -c "frontmatter-pattern"
+```
+
+## Deploy workflow template (bun-source, not Nix) — build in CI, deploy-only on VPS
+
+> **User correction (2026-08-21):** "alur ci nya juga benarkan lah masa build
+> di vps,harusnya kan di vps hanya deploy,dan seharusnya pakai nix"
+
+The VPS must **not** build. Build happens in CI; the VPS only deploys the
+pre-built artifact. Use a single workflow with a `needs:` chain (not
+`workflow_run` — see pitfall #8 below).
+
+### Pitfalls for bun-source deploy workflows
+
+- **`bun --cwd X run Y` is broken.** `bun run` does NOT accept `--cwd` as a
+  subcommand flag — it prints usage and exits 0 (silent failure). Use
+  `working-directory: X` in the step, or `cd X && bun run Y`. (Root cause of
+  CI appearing to pass while the build never actually ran. This also affects
+  the smoke test step: `bun --cwd apps/mcp run smoke` was silently failing.)
+- **`.next/` is a hidden directory.** `actions/upload-artifact@v4` excludes
+  hidden files/dirs by default (`include-hidden-files: false`). Set
+  `include-hidden-files: true` or the artifact will be empty.
+- **`workflow_run` cannot download artifacts from the CI run.** This is a
+  known GitHub Actions limitation — the deploy workflow doesn't have access to
+  the CI run's artifacts. **Fix:** merge CI + deploy into a single workflow with
+  `deploy: needs: [build]`.
+- **`actions/checkout@v4` → Node 20 deprecation.** Bump to `@v5`.
+- **SCP'ing hundreds of individual files from `.next/` can time out.** Tar first,
+  then SCP the single tarball: `tar -czf app.tar.gz .next`, SCP, then SSH to
+  unpack. Also exclude `.next/cache/` to reduce size (~73MB → ~49MB).
+- **`download-artifact` path resolution.** When downloading with
+  `path: apps/web/.next`, the artifact (which contains the `.next` directory
+  contents from upload `path: apps/web/.next`) gets extracted correctly to
+  `apps/web/.next/`. Do NOT use `path: .next` — that creates `.next/.next/`.

 # MCPedia Agent Instructions
 
-MCPedia is a content-first knowledge base where Markdown files under `content/` serve as the Git-tracked source of truth, indexed into PostgreSQL and accessed via Web UI, tRPC API, and Model Context Protocol (MCP).
+MCPedia is a content-first knowledge base where documents are stored in **PostgreSQL** as the source of truth (with auto-generated .md backups on disk), indexed into embeddings + search vectors, and accessed via Web UI, tRPC API, and Model Context Protocol (MCP).
+
+- **DB-first**: Documents are created/updated/deleted via the MCP `create_document`/`update_document`/`delete_document` tools (require `x-webhook-secret`). Filesystem `.md` files in `content/` are auto-generated backups (gitignored).
+- **Git-sync deploy**: CI builds `.next` on GitHub Actions → tarball → SCP to VPS → unpack. VPS never builds. Content changes flow via MCP API to the DB directly.
 
 ## Architecture Principles
 
 1. **Single Core Layer (`@mcpedia/core`)**: All business logic (document CRUD, indexing, search, revisions, path classification) resides in `packages/core`. Never access the database directly from `apps/web`, `apps/mcp`, or `apps/api`.
-2. **Content as Source of Truth**: Markdown files in `content/` with YAML frontmatter are the primary data store. The database stores metadata, search vectors, embeddings, and revision history.
+2. **DB as Source of Truth**: PostgreSQL stores document body + metadata. Filesystem `.md` files in `content/` are auto-generated backups (gitignored). Use the MCP `create_document`/`update_document` tools to write content.
 3. **Multi-Modal Search**: Keyword search (Postgres FTS `tsvector` + GIN), Semantic search (cosine similarity over chunked embeddings), and Hybrid search (Reciprocal Rank Fusion / RRF) are unified in `@mcpedia/search`.
 4. **Mutations & Security**: State-changing operations (document creation/updates/deletions, reindexing, revision restoration) require authentication (`x-webhook-secret` header or session cookie).
