+# MincedPad 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:** Build a self-hosted anonymous paste/file share app (MincedPad) with public wall, TTL/burn, admin moderation, Docker deploy, and mobile-usable UI.
+
+**Architecture:** FastAPI + SQLite + local uploads in one process; Vue3/Element Plus SPA built into the image and served by FastAPI; in-memory per-IP rate limit; background cleaner for expiry.
+
+**Tech Stack:** Python 3.12, FastAPI, SQLAlchemy, SQLite, python-jose/passlib or PyJWT, Vue 3, Vite, Element Plus, TypeScript, Docker multi-stage.
+
+**Spec:** `docs/superpowers/specs/2026-07-14-mincedpad-design.md`

+### Task 1: Backend skeleton (config, DB, models)
+
+**Files:**
+- Create: `backend/requirements.txt`
+- Create: `backend/app/__init__.py`
+- Create: `backend/app/config.py`
+- Create: `backend/app/db.py`
+- Create: `backend/app/models.py`
+- Create: `backend/app/main.py` (minimal health)
+
+- [ ] **Step 1: Add dependencies**
+
+```text

+
+class Settings(BaseSettings):
+    data_dir: Path = Path("/data")

+
+    @property
+    def uploads_dir(self) -> Path:
+        return self.data_dir / "uploads"
+
+settings = Settings()
+```
+
+Also add `pydantic-settings==2.7.0` to requirements.
+
+- [ ] **Step 3: DB + models**
+
+```python
+# backend/app/models.py (essentials)
+class Item(Base):
+    __tablename__ = "items"
+    id: Mapped[int] = mapped_column(primary_key=True)
+    slug: Mapped[str] = mapped_column(String(32), unique=True, index=True)

+    reason: Mapped[str] = mapped_column(String(255), default="")
+    created_at: Mapped[datetime] = mapped_column(DateTime, default=datetime.utcnow)
+```
+
+- [ ] **Step 4: Minimal app with `/api/health`**
+
+```python
+@app.get("/api/health")
+def health():
+    return {"ok": True, "name": "MincedPad"}
+```
+
+On startup: `settings.data_dir.mkdir`, `uploads_dir.mkdir`, `Base.metadata.create_all`.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add backend
+git commit -m "feat: scaffold FastAPI app, config, and SQLite models"
+```
+
+---
+
+### Task 2: Item service + public create/get/wall APIs
+
+**Files:**
+- Create: `backend/app/schemas.py`
+- Create: `backend/app/services/items.py`
+- Create: `backend/app/api/public.py`
+- Create: `backend/tests/conftest.py`
+- Create: `backend/tests/test_items.py`
+- Modify: `backend/app/main.py` — include router
+
+- [ ] **Step 1: Write failing tests**
+
+```python
+def test_create_text_default_public_and_24h(client):
+    r = client.post("/api/items", json={"body": "hello **md**"})
+    assert r.status_code == 200
+    data = r.json()
+    assert data["slug"]
+    assert data["is_public"] is True
+    assert data["expires_at"] is not None
+
+def test_link_only_not_on_wall(client):
+    r = client.post("/api/items", json={"body": "secret", "is_public": False})
+    slug = r.json()["slug"]
+    wall = client.get("/api/items/wall").json()["items"]
+    assert all(i["slug"] != slug for i in wall)
+    assert client.get(f"/api/items/{slug}").status_code == 200
+```
+
+- [ ] **Step 2: Run tests — expect FAIL**
+
+```bash
+cd backend && PYTHONPATH=. pytest tests/test_items.py -v
+```
+
+- [ ] **Step 3: Implement schemas + `items` service**
+
+- Slug: `secrets.token_urlsafe(8)` trimmed to URL-safe short id  
+- TTL map: `1h`→+1h, `24h`→+24h, `7d`→+7d, `never`→`None`  
+- `get_item`: 404 if missing/expired/`burned`; if `burn_after_read` and not yet burned, return once then set `burned=True` and delete file if any  
+- Wall: `is_public==True`, not burned, not expired, order by `created_at desc`
+
+- [ ] **Step 4: Wire `POST /api/items`, `GET /api/items/wall`, `GET /api/items/{slug}`**
+
+Client IP from `request.client.host` (and honor `X-Forwarded-For` first hop when present for Docker proxy later).
+
+- [ ] **Step 5: Tests PASS, then commit**
+
+```bash
+git commit -m "feat: public text items, wall, and detail API"
+```
+
+---
+
+### Task 3: File upload, allowlist, download
+
+**Files:**
+- Create: `backend/app/services/storage.py`
+- Modify: `backend/app/api/public.py`
+- Modify: `backend/tests/test_items.py`
+
+- [ ] **Step 1: Failing tests for upload + size reject**
+
+```python
+def test_upload_small_file(client, tmp_path):
+    files = {"file": ("hi.txt", b"abc", "text/plain")}
+    data = {"is_public": "true", "ttl": "24h"}
+    r = client.post("/api/items/upload", files=files, data=data)
+    assert r.status_code == 200
+    slug = r.json()["slug"]
+    f = client.get(f"/api/items/{slug}/file")
+    assert f.status_code == 200
+    assert f.content == b"abc"
+
+def test_reject_oversize(client, monkeypatch):
+    monkeypatch.setenv("MAX_UPLOAD_MB", "1")
+    # re-load settings or override app dependency — use 1MB+ body
+    ...
+```
+
+For oversize test, override `settings.max_upload_mb = 1` in fixture if env reload is awkward.
+
+- [ ] **Step 2: Implement `storage.save_upload(file) -> (rel_path, size, mime, safe_name)`**
+
+Allowlist extensions from spec. Reject others with 400.
+
+- [ ] **Step 3: `POST /api/items/upload` + `GET /api/items/{slug}/file`**
+
+Use `FileResponse` with correct `media_type`; images `Content-Disposition: inline`.
+
+- [ ] **Step 4: Tests PASS, commit**
+
+```bash
+git commit -m "feat: file upload, allowlist, and download/preview"
+```
+
+---
+
+### Task 4: Rate limit (2/s) + IP bans on writes
+
+**Files:**
+- Create: `backend/app/services/rate_limit.py`
+- Create: `backend/app/services/bans.py`
+- Modify: `backend/app/api/public.py`
+- Modify: `backend/tests/test_items.py`
+
+- [ ] **Step 1: Failing tests**
+
+```python
+def test_rate_limit_third_request_in_same_second(client):
+    # three quick creates → last is 429
+    ...
+
+def test_banned_ip_cannot_create(client, db):
+    db.add(BannedIP(ip="testclient"))
+    ...
+    assert client.post("/api/items", json={"body": "x"}).status_code == 403
+```
+
+Note: Starlette TestClient IP is often `testclient` — assert against that or inject dependency.
+
+- [ ] **Step 2: Sliding window: deque of timestamps per IP; allow if `< rate_limit_per_second` in last 1.0s**
+
+- [ ] **Step 3: Ban check before create/upload**
+
+- [ ] **Step 4: Tests PASS, commit**
+
+```bash
+git commit -m "feat: per-IP rate limit and write bans"
+```
+
+---
+
+### Task 5: Cleaner + burn-after-read verification
+
+**Files:**
+- Create: `backend/app/services/cleaner.py`
+- Modify: `backend/app/main.py` — start background task
+- Modify: `backend/tests/test_items.py`
+
+- [ ] **Step 1: Test burn**
+
+```python
+def test_burn_after_read(client):
+    r = client.post("/api/items", json={"body": "once", "burn_after_read": True, "ttl": "never"})
+    slug = r.json()["slug"]
+    assert client.get(f"/api/items/{slug}").status_code == 200
+    assert client.get(f"/api/items/{slug}").status_code == 404
+```
+
+- [ ] **Step 2: Test cleaner removes expired**
+
+Create item with `expires_at` in the past via service/DB, run `cleaner.run_once(db)`, assert gone.
+
+- [ ] **Step 3: Implement lifespan task `asyncio.sleep(60)` loop calling `run_once`**
+
+- [ ] **Step 4: Commit**
+
+```bash
+git commit -m "feat: burn-after-read and expiry cleaner"
+```
+
+---
+
+### Task 6: Admin auth + moderation APIs
+
+**Files:**
+- Create: `backend/app/security.py`
+- Create: `backend/app/api/admin.py`
+- Create: `backend/tests/test_admin.py`
+- Modify: `backend/app/main.py`
+
+- [ ] **Step 1: Tests for login, delete item, ban/unban**
+
+```python
+def test_admin_login_and_delete(client):
+    token = client.post("/api/admin/login", json={"password": "changeme"}).json()["token"]
+    headers = {"Authorization": f"Bearer {token}"}
+    slug = client.post("/api/items", json={"body": "bye"}).json()["slug"]
+    items = client.get("/api/admin/items", headers=headers).json()["items"]
+    item_id = next(i["id"] for i in items if i["slug"] == slug)
+    assert client.delete(f"/api/admin/items/{item_id}", headers=headers).status_code == 200
+    assert client.get(f"/api/items/{slug}").status_code == 404
+```
+
+- [ ] **Step 2: JWT create/verify with `SECRET_KEY`; password compare to `ADMIN_PASSWORD`**
+
+- [ ] **Step 3: Implement admin routes from spec**
+
+- [ ] **Step 4: Commit**
+
+```bash
+git commit -m "feat: admin login, delete items, and IP bans API"
+```
+
+---
+
+### Task 7: Frontend scaffold (Vue3 + Element Plus, mobile-first)
+
+**Files:**
+- Create: `frontend/package.json`, `vite.config.ts`, `index.html`, `src/main.ts`, `src/App.vue`, `src/router/index.ts`, `src/api/client.ts`, `src/styles.css`
+
+- [ ] **Step 1: Scaffold with Vite vue-ts; add `element-plus`, `vue-router`, `markdown-it`**
+
+```bash
+cd frontend && npm create vite@latest . -- --template vue-ts
+npm i element-plus vue-router markdown-it
+npm i -D @types/markdown-it
+```
+
+- [ ] **Step 2: Vite proxy `/api` → `http://127.0.0.1:8080` for dev**
+
+- [ ] **Step 3: Global CSS**
+
+```css
+html, body, #app { margin: 0; min-height: 100%; }
+.page { max-width: 960px; margin: 0 auto; padding: 12px 16px 32px; }
+@media (max-width: 768px) {
+  .page { padding: 8px 12px 24px; }
+  .desktop-only { display: none !important; }
+}
+```
+
+- [ ] **Step 4: Router routes `/`, `/p/:slug`, `/admin`**
+
+- [ ] **Step 5: Viewport meta in `index.html`:**  
+  `width=device-width, initial-scale=1, viewport-fit=cover`
+
+- [ ] **Step 6: Commit**
+
+```bash
+git commit -m "feat: scaffold Vue3 Element Plus frontend with mobile base"
+```
+
+---
+
+### Task 8: Home page — composer + wall (responsive)
+
+**Files:**
+- Create: `frontend/src/views/HomeView.vue`
+- Create: `frontend/src/components/Composer.vue`
+- Create: `frontend/src/components/WallList.vue`
+
+- [ ] **Step 1: Layout with `el-row` / `el-col :xs="24" :md="12"`** — stack on phone
+
+- [ ] **Step 2: Composer controls**
+
+- Markdown `el-input` type textarea  
+- TTL `el-select` default `24h`  
+- Switches: burn, link-only  
+- Buttons full-width on `xs`  
+- Upload: `el-upload` drag + `accept` + mobile falls back to file picker  
+
+- [ ] **Step 3: On success show share URL with copy button (`navigator.clipboard`)**
+
+- [ ] **Step 4: Wall list cards; poll `GET /api/items/wall` every 15s; tap navigates to `/p/:slug`**
+
+- [ ] **Step 5: Manual check at 375px width (browser device mode)**
+
+- [ ] **Step 6: Commit**
+
+```bash
+git commit -m "feat: home composer and public wall UI"

+
+---
+
+### Task 9: Detail + Admin views
+
+**Files:**

+- Create: `frontend/src/views/AdminView.vue`
+
+- [ ] **Step 1: ItemView — fetch slug; render markdown via markdown-it; images `<img>` from `/api/items/:slug/file`; other types download link**
+
+- [ ] **Step 2: If API returns burn hint / first open, show `el-alert` once**
+
+- [ ] **Step 3: AdminView — password form; store JWT in `sessionStorage`; tables for items/bans; touch-friendly row actions**
+
+- [ ] **Step 4: Commit**
+
+```bash

+```
+
+---
+
+### Task 10: Serve SPA from FastAPI + Docker Compose
+
+**Files:**
+- Modify: `backend/app/main.py` — mount `frontend/dist`, SPA fallback
+- Create: `Dockerfile`
+- Create: `docker-compose.yml`
+- Create: `.dockerignore`
+- Create: `.gitignore`
+- Create: `README.md`
+
+- [ ] **Step 1: Static mount**
