# Publish-Pipeline Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Eine Deno-basierte Toolchain bauen, die Markdown-Posts aus `content/posts/*/index.md` in signierte `kind:30023`-Events umwandelt, alle Bilder zu Blossom hochlädt und die Events zu Public-Relays publisht — sowohl lokal per CLI als auch automatisch per GitHub Action beim Push auf `main`.

**Architecture:** Gemeinsame Library (`src/core/`) + CLI-Entrypoint (`src/cli.ts`) + Subcommands (`src/subcommands/`). Signatur via NIP-46-Bunker (Amber), Config aus Nostr (`kind:10002` Relays, `kind:10063` Blossom), Change-Detection via Git-Diff. State-los im Repo, keine Lock-Files. **Einheitlicher Upload-Pfad:** alle Bilder (Alt- wie Neuposts) landen auf Blossom. Kein rsync, kein Legacy-Pfad.

**Blaupausen-Prinzip:** Der Code enthält **keine** projekt-spezifischen Konstanten. Alle Werte (Pubkey, Relay, Content-Pfad, Client-Tag) kommen aus Env-Variablen. `publish/` ist als eigenständiges Verzeichnis gedacht, das in andere Nostr-Repos per Submodule oder Template übernommen werden kann.

**Tech Stack:** Deno 2.x, TypeScript, `applesauce-signers` (NIP-46), `applesauce-relay` (RxJS), `nostr-tools` (Event-Bau/Verify), `@std/yaml`, `@std/cli`, `@std/fs`, `@std/path`, `@std/testing`. Zielordner: `publish/` auf Repo-Root.

---

## Phase 1 — Projekt-Setup

### Task 1: Deno-Projekt-Grundgerüst

**Files:**
- Create: `publish/deno.jsonc`
- Create: `publish/.gitignore`
- Create: `publish/.env.example`
- Create: `publish/README.md`

**Env-Handling:** Die Pipeline liest ausschließlich aus Env-Variablen — keine hardcoded Projekt-Konstanten im Code. Lade-Reihenfolge (Deno 2.x lädt die erste existierende Datei):

1. `publish/.env` — lokale Publish-Config (gitignored, Template: `publish/.env.example`).
2. Fallback: `../.env.local` im Repo-Root, falls vorhanden (für Repos, die schon eine `.env.local` pflegen).
3. In CI: GitHub-Actions-Secrets werden als Prozess-Env injiziert.

Für dieses Projekt existiert bereits `../.env.local` mit `BUNKER_URL`, `AUTHOR_PUBKEY_HEX`, `BOOTSTRAP_RELAY`. Die Pipeline-`deno.jsonc` nutzt primär `../.env.local` per `--env-file`. In einem Fremd-Repo, das `publish/` einbindet, würde stattdessen `publish/.env` angelegt und der `--env-file`-Pfad angepasst (oder `.env.example` kopiert).

- [ ] **Step 1: Verzeichnis anlegen und `deno.jsonc` schreiben**

`publish/deno.jsonc`:

```jsonc
{
  "tasks": {
    "publish": "deno run --env-file=../.env.local --allow-env --allow-read --allow-write=./logs --allow-net --allow-run=git src/cli.ts publish",
    "check": "deno run --env-file=../.env.local --allow-env --allow-read --allow-net src/cli.ts check",
    "validate-post": "deno run --allow-read src/cli.ts validate-post",
    "test": "deno test --allow-env --allow-read --allow-net --allow-run",
    "fmt": "deno fmt",
    "lint": "deno lint"
  },
  "imports": {
    "@std/yaml": "jsr:@std/yaml@^1.0.5",
    "@std/cli": "jsr:@std/cli@^1.0.6",
    "@std/fs": "jsr:@std/fs@^1.0.4",
    "@std/path": "jsr:@std/path@^1.0.6",
    "@std/testing": "jsr:@std/testing@^1.0.3",
    "@std/assert": "jsr:@std/assert@^1.0.6",
    "@std/encoding": "jsr:@std/encoding@^1.0.5",
    "nostr-tools": "npm:nostr-tools@^2.10.4",
    "applesauce-signers": "npm:applesauce-signers@^2.0.0",
    "applesauce-relay": "npm:applesauce-relay@^2.0.0",
    "rxjs": "npm:rxjs@^7.8.1"
  },
  "fmt": {
    "lineWidth": 100,
    "indentWidth": 2,
    "semiColons": false,
    "singleQuote": true
  },
  "lint": {
    "rules": {
      "tags": ["recommended"]
    }
  }
}
```

- [ ] **Step 2: `publish/.gitignore` schreiben**

```
.env
logs/
```

- [ ] **Step 3: `publish/.env.example` schreiben (Template für Fremd-Repos)**

```
# ==== PFLICHT ====

# NIP-46-Bunker-URL vom Signer (Amber, nak bunker, nsite.run, …)
BUNKER_URL=bunker://<hex>?relay=wss://...&secret=...

# Autor-Pubkey als 64 Zeichen lowercase hex (entspricht dem Bunker-Account)
AUTHOR_PUBKEY_HEX=

# Bootstrap-Relay zum Laden von kind:10002 und kind:10063
BOOTSTRAP_RELAY=wss://relay.damus.io

# ==== OPTIONAL ====

# Wurzel der Markdown-Posts, relativ zu diesem publish/-Ordner.
# Default: ../content/posts
CONTENT_ROOT=../content/posts

# Wird als ["client", "<wert>"]-Tag in jedes kind:30023-Event eingetragen.
# Hilft bei der Zuordnung der Event-Herkunft. Default: joerglohrerde-publish
CLIENT_TAG=joerglohrerde-publish

# Minimal geforderte Relay-ACKs pro Post (default: 2)
MIN_RELAY_ACKS=2
```

- [ ] **Step 4: `publish/README.md` schreiben**

```markdown
# publish — Nostr-Publish-Pipeline

Markdown-Posts aus einem Hugo-ähnlichen Content-Ordner zu `kind:30023`-Events,
Bilder zu Blossom, Signatur via NIP-46-Bunker.

Blaupause für Nostr-Repos: keinerlei Projekt-Konstanten im Code, alles über
Env-Variablen konfigurierbar.

## Setup

1. `cp .env.example .env` und Werte eintragen.
2. Oder: `.env.local` im Eltern-Ordner pflegen und `deno.jsonc` anpassen
   (siehe `--env-file=../.env.local`-Tasks).
3. `deno task check` — verifiziert Bunker, Relay-Liste, Blossom-Server.

## Befehle

- `deno task publish` — Git-Diff-Modus: publisht nur geänderte Posts.
- `deno task publish --force-all` — alle Posts (Migration / Reimport).
- `deno task publish --post <slug>` — nur ein Post.
- `deno task publish --dry-run` — zeigt, was publiziert würde, ohne Uploads.
- `deno task validate-post content/posts/<ordner>/index.md` — Frontmatter-Check.
- `deno task test` — Tests.

## Struktur

- `src/core/` — Library (Frontmatter, Markdown, Events, Signer, Relays, Blossom).
- `src/subcommands/` — CLI-Befehle.
- `src/cli.ts` — Entrypoint, Subcommand-Dispatcher.
- `tests/` — Unit- und Integration-Tests.
- `.github/workflows/publish.yml` — CI-Workflow.
```

- [ ] **Step 5: Verifikation + Commit**

Run: `cd publish && deno fmt --check deno.jsonc`
Expected: PASS (kein Output)

```bash
git add publish/deno.jsonc publish/.gitignore publish/.env.example publish/README.md
git commit -m "publish(task 1): deno-grundgerüst (deno.jsonc, .env.example, readme)"
```

- [ ] **Step 2: Smoke-Test**

Run: `cd publish && deno run src/cli.ts`
Expected: Usage-Message, Exit-Code 2.

Run: `cd publish && deno run --allow-read src/cli.ts validate-post tests/fixtures/sample-post.md`
Expected: `✓ tests/fixtures/sample-post.md ok (slug: sample-slug)`

- [ ] **Step 3: Commit**

```bash
git add publish/src/cli.ts
git commit -m "publish(task 18): cli-entrypoint mit subcommand-dispatch"
```

---

## Phase 7 — Pre-Flight gegen reale Infrastruktur

### Task 19: `deno task check` gegen Amber + Relays + Blossom

**Files:** keine Änderungen — nur Verifikation.

- [ ] **Step 1: `deno task check` laufen lassen**

Run: `cd publish && deno task check`

Erwartung: `✓ pre-flight ok`. Bei Fehlern:
- **Bunker-Ping-Timeout:** Amber öffnen, Akku-Optimierung deaktivieren, Permission für Pipeline-App auf auto-approve für `kind:30023` und `kind:24242` setzen.
- **kind:10002 fehlt / leer:** siehe Spec §2.3 — Event manuell publizieren.
- **kind:10063 fehlt / leer:** siehe Spec §2.4 — Event manuell publizieren.
- **Blossom-Server 4xx/5xx:** anderen Server in `kind:10063` eintragen.

- [ ] **Step 2: Kein Commit. Nur Verifikation.**

---

## Phase 8 — Integrationstest: Einzel-Post

### Task 20: Dry-run + echte Publikation eines einzelnen Posts

**Files:** keine Änderungen.

- [ ] **Step 1: Dry-run**

Run:
```bash
cd publish && deno task publish --post offenheit-das-wesentliche --dry-run
```

Expected: `mode=post-single posts=1 runId=<uuid>` + `dry-run: content/posts/2024-01-16-offenheit-das-wesentliche`.

- [ ] **Step 2: Echte Einzel-Publikation**

```bash
cd publish && deno task publish --post offenheit-das-wesentliche
```

Beobachten:
- Amber zeigt N Signatur-Requests: 1 × `kind:30023` (Event) + M × `kind:24242` (Blossom-Auth, pro Bild).
- Auto-approve sollte alle ohne manuellen Tap durchwinken.
- Log: `images_uploaded: M`, `relays_ok.length ≥ 2`.

Expected-Exit-Code: 0, Log in `publish/logs/publish-*.json`.

- [ ] **Step 3: Event auf Relay verifizieren**

```bash
nak req -k 30023 -a 4fa5d1c413e2b45e10d40bf3562ab701a5331206e359c90baae0e99bfd6c6e41 --tag d=offenheit-das-wesentliche wss://relay.damus.io 2>/dev/null | jq -c '{id, kind, tags: (.tags[:5])}'
```

Expected: genau 1 Event mit `d`, `title`, `published_at`, `summary`, `image`-Tags.

- [ ] **Step 4: Bild auf Blossom verifizieren**

URL aus dem Event-Content (`content`) herausziehen, per `curl -sI` prüfen. Erwartung: HTTP 200.

- [ ] **Step 5: Live-Check auf der SPA**

Öffne `https://svelte.joerg-lohrer.de/`, der Post sollte in der Liste erscheinen. Bilder laden von Blossom, Layout okay?

**Wenn Probleme auftreten, HIER STOPPEN** und mit dem User debuggen, bevor `--force-all` läuft.

---

## Phase 9 — Massen-Migration

### Task 21: Alle 18 Posts publizieren

**Files:** keine Code-Änderung.

- [ ] **Step 1: Event-Stand vor der Migration sichern**

```bash
nak req -k 30023 -a 4fa5d1c413e2b45e10d40bf3562ab701a5331206e359c90baae0e99bfd6c6e41 wss://relay.damus.io 2>/dev/null | jq -s 'length'
```

Zahl notieren (sollte ~10 sein, siehe STATUS.md).

- [ ] **Step 2: Dry-run auf alle**

```bash
cd publish && deno task publish --force-all --dry-run
```

Expected: `mode=force-all posts=18`.

- [ ] **Step 3: Echte Migration**

```bash
cd publish && deno task publish --force-all
```

Beobachten:
- Amber online, Akku-Optimierung aus, Auto-Approve aktiv.
- Pipeline läuft sequenziell.
- 18 `kind:30023`-Signaturen + N × `kind:24242` (pro Bild eines).
- Erwartet: ~3–5 min Gesamtlaufzeit bei ~90 Bildern.

Expected: Exit-Code 0, Log mit 18 Einträgen, alle `status: success`.

- [ ] **Step 4: Verifikation auf Relay**

```bash
nak req -k 30023 -a 4fa5d1c413e2b45e10d40bf3562ab701a5331206e359c90baae0e99bfd6c6e41 wss://relay.damus.io 2>/dev/null | jq -s 'length'
```

Expected: `18`.

- [ ] **Step 5: SPA-Stichprobe**

Mindestens 5 Posts auf `https://svelte.joerg-lohrer.de/` durchklicken. Bilder laden? Kommentare erreichbar? Layout korrekt?

- [ ] **Step 6: Log archivieren**

```bash
mkdir -p docs/publish-logs
cp publish/logs/publish-*.json docs/publish-logs/2026-04-16-force-all-migration.json
git add docs/publish-logs/2026-04-16-force-all-migration.json
git commit -m "docs: publish-pipeline force-all migration log"
```

---

## Phase 10 — GitHub-Actions-Workflow

### Task 22: CI-Workflow

**Files:**
- Create: `.github/workflows/publish.yml`

- [ ] **Step 1: Workflow schreiben**

`.github/workflows/publish.yml`:

```yaml
name: Publish Nostr Events

on:
  push:
    branches: [main]
    paths: ['content/posts/**']
  workflow_dispatch:
    inputs:
      force_all:
        description: 'Publish all posts (--force-all)'
        type: boolean
        default: false

jobs:
  publish:
    runs-on: ubuntu-latest
    timeout-minutes: 30
    steps:
      - uses: actions/checkout@v4
        with:
          fetch-depth: 0

      - uses: denoland/setup-deno@v2
        with:
          deno-version: v2.x

      - name: Pre-Flight Check
        working-directory: ./publish
        env:
          BUNKER_URL: ${{ secrets.BUNKER_URL }}
          AUTHOR_PUBKEY_HEX: ${{ secrets.AUTHOR_PUBKEY_HEX }}
          BOOTSTRAP_RELAY: ${{ secrets.BOOTSTRAP_RELAY }}
        run: |
          deno run --allow-env --allow-read --allow-net src/cli.ts check

      - name: Publish
        working-directory: ./publish
        env:
          BUNKER_URL: ${{ secrets.BUNKER_URL }}
          AUTHOR_PUBKEY_HEX: ${{ secrets.AUTHOR_PUBKEY_HEX }}
          BOOTSTRAP_RELAY: ${{ secrets.BOOTSTRAP_RELAY }}
          GITHUB_EVENT_BEFORE: ${{ github.event.before }}
        run: |
          if [ "${{ github.event.inputs.force_all }}" = "true" ]; then
            deno run --allow-env --allow-read --allow-write=./logs --allow-net --allow-run=git src/cli.ts publish --force-all
          else
            deno run --allow-env --allow-read --allow-write=./logs --allow-net --allow-run=git src/cli.ts publish
          fi

      - uses: actions/upload-artifact@v4
        if: always()
        with:
          name: publish-log
          path: ./publish/logs/publish-*.json
          retention-days: 30
```

- [ ] **Step 2: GitHub-Actions-Secrets anlegen (manueller Schritt)**

Settings → Secrets and variables → Actions → New repository secret:
- `BUNKER_URL`
- `AUTHOR_PUBKEY_HEX` = `4fa5d1c413e2b45e10d40bf3562ab701a5331206e359c90baae0e99bfd6c6e41`
- `BOOTSTRAP_RELAY` = `wss://relay.primal.net`

- [ ] **Step 3: Alle Tests laufen**

Run: `cd publish && deno task test`
Expected: alle PASS.

- [ ] **Step 4: Commit und Push**

```bash
git add .github/workflows/publish.yml
git commit -m "publish(task 22): github-actions-workflow für auto-publish"
git push origin spa
```

- [ ] **Step 5: Workflow manuell triggern (ohne force)**

GitHub-UI → Actions → „Publish Nostr Events" → „Run workflow" → Branch `spa`. Erwartung: Check läuft grün, keine Content-Änderung → 0 Posts, Exit-Code 0.

- [ ] **Step 6: End-to-End-Test mit Content-Commit**

Minimalen Edit in einem Post machen, pushen. Workflow sollte automatisch triggern, Post re-publishen. Log-Artefakt prüfen.

---

## Phase 11 — Abschluss

### Task 23: Dokumentation aktualisieren

**Files:**
- Modify: `docs/STATUS.md`
- Modify: `docs/HANDOFF.md`

- [ ] **Step 1: STATUS.md aktualisieren**

- §2 „Was auf Nostr liegt": Event-Zahl auf 18 aktualisieren, Blossom-Erläuterung („alle Bilder auf Blossom").
- §6 „Offene Punkte": Publish-Pipeline als erledigt markieren. Menü-Nav + Impressum + Cutover bleiben offen.

- [ ] **Step 2: HANDOFF.md aktualisieren**

- „Option 1 — Publish-Pipeline" → Status: erledigt.
- Neues „Was als Nächstes":
  - Option 2 (Menü-Navigation + Impressum)
  - Option 3 (Cutover: Hauptdomain `joerg-lohrer.de` auf SvelteKit umstellen — Voraussetzung Publish-Pipeline live; jetzt möglich).

- [ ] **Step 3: Commit**

```bash
git add docs/STATUS.md docs/HANDOFF.md
git commit -m "docs: publish-pipeline als erledigt markiert, cutover freigegeben"
```

---

### Task 24: Merge nach `main`

**Files:** keine.

- [ ] **Step 1: Alle Tests**

Run: `cd publish && deno task test`
Run: `cd app && npm run check && npm run test:unit && npm run test:e2e`
Expected: alle PASS.

- [ ] **Step 2: Push**

```bash
git push origin spa
```

- [ ] **Step 3: Mit User besprechen, ob `spa` → `main` gemergt wird**

Kein automatischer Merge. Entscheidung beim User. Ende.

---

## Gesamte Verifikation

- [ ] `cd publish && deno task test` → alle PASS.
- [ ] `cd publish && deno task check` → `✓ pre-flight ok`.
- [ ] `curl -sI https://svelte.joerg-lohrer.de/` → 200.
- [ ] `nak req -k 30023 -a 4fa5d1c413e2b45e10d40bf3562ab701a5331206e359c90baae0e99bfd6c6e41 wss://relay.damus.io 2>/dev/null | jq -s 'length'` → 18 oder mehr.
- [ ] GitHub Actions Workflow grün.
