# travel-memories 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 local Flask web app that turns Immich photo albums into Grav CMS journal entries and story pages via a six-phase guided workflow.

**Architecture:** Flask backend per phase blueprint, state persisted as atomic JSON per album, all Immich calls proxied server-side. DaisyUI + Alpine.js loaded from CDN — no build pipeline. Playwright drives UI tests against a dev server backed by a mock Immich server (pytest-httpserver).

**Tech Stack:** Python 3.12, Flask, DaisyUI 4 + Tailwind CSS (CDN), Alpine.js 3 (CDN), SortableJS (CDN, Phase 3 drag), Playwright + pytest, pytest-httpserver, docker-compose

## Global Constraints

- Python 3.12 only; no dependencies beyond `requirements.txt`
- All Immich HTTP calls go through Flask proxy routes — API key never reaches the browser
- State written atomically: write to `{path}.tmp` then `os.rename()` — never write directly
- `status: exported` on a group is immutable; no code path may change it
- DaisyUI theme: `forest` throughout
- No AI-generated text in any output
- `user/pages/` written directly by export; caller runs `make content-push` afterwards
- Pre-implementation gate: verify Immich API endpoint paths against real instance before Task 3

## Task 1: Scaffold — Docker, requirements, Flask factory, test infrastructure

**Files:**
- Create: `services/travel-memories/Dockerfile`
- Create: `services/travel-memories/requirements.txt`
- Create: `services/travel-memories/app/__init__.py`
- Create: `services/travel-memories/app/routes/__init__.py`
- Create: `services/travel-memories/tests/conftest.py`
- Create: `services/travel-memories/tests/fixtures/phase2_state.json` (and phase3–6)
- Modify: `docker-compose.yml`
- Modify: `.gitignore`

**Interfaces:**
- Produces: `create_app(state_dir=None, pages_dir=None) -> Flask` — consumed by every later task's tests

- [ ] **Step 1: Create `requirements.txt`**

```
flask==3.1.0
requests==2.32.3
pytest==8.3.4
pytest-playwright==0.6.2
pytest-httpserver==1.1.0
```

- [ ] **Step 2: Create `Dockerfile`**

```dockerfile
FROM python:3.12-slim
WORKDIR /app
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt && \
    playwright install chromium --with-deps
COPY app/ ./app/
ENV FLASK_APP=app
ENV FLASK_RUN_HOST=0.0.0.0
ENV FLASK_RUN_PORT=8082
CMD ["flask", "run"]
```

- [ ] **Step 3: Create `app/__init__.py`**

```python
import os
from flask import Flask

def create_app(state_dir=None, pages_dir=None):
    app = Flask(__name__)
    app.config["STATE_DIR"] = state_dir or os.environ.get("STATE_DIR", "/app/state")
    app.config["PAGES_DIR"] = pages_dir or os.environ.get("PAGES_DIR", "/app/pages")
    app.config["IMMICH_URL"] = os.environ.get("IMMICH_URL", "")
    app.config["IMMICH_API_KEY"] = os.environ.get("IMMICH_API_KEY", "")

    from .routes import albums, proxy, notes, nav
    app.register_blueprint(albums.bp)
    app.register_blueprint(proxy.bp)
    app.register_blueprint(notes.bp)
    app.register_blueprint(nav.bp)

    @app.get("/health")
    def health():
        return {"ok": True}

    return app
```

(Remaining blueprints added in Tasks 5–10.)

- [ ] **Step 4: Create `app/routes/__init__.py`** — empty file.

- [ ] **Step 5: Add `travel-memories` service to `docker-compose.yml`**

```yaml
  travel-memories:
    build: ./services/travel-memories
    ports:
      - "8082:8082"
    volumes:
      - ./docs/immich-workflow:/app/state
      - ./user/pages:/app/pages
    env_file: .env
    user: "${UID}:${GID}"
```

- [ ] **Step 6: Update `.gitignore`** — add line: `docs/immich-workflow/*.json`

- [ ] **Step 13: Write a smoke test**

Create `tests/test_smoke.py`:

```python
def test_health(base_url, page):
    page.goto(f"{base_url}/health")
    assert "ok" in page.content()
```

- [ ] **Step 14: Run smoke test**

```bash
cd services/travel-memories
pip install -r requirements.txt
playwright install chromium
pytest tests/test_smoke.py -v
```

Expected: PASS

- [ ] **Step 15: Commit**

```bash
git add services/travel-memories/ docker-compose.yml .gitignore
git commit -m "feat: scaffold travel-memories Flask app and test infrastructure"
```

## Task 2: State management

**Files:**
- Create: `services/travel-memories/app/state.py`
- Create: `services/travel-memories/tests/test_state.py`

**Interfaces:**
- Produces: `load_state(album_id, app) -> TripState | None`
- Produces: `save_state(state: TripState, app) -> None`
- Produces: `TripState`, `Photo`, `Group` dataclasses with fields matching spec JSON

## Task 8: Phase 4 — Group

**Files:**
- Create: `app/routes/group.py`
- Create: `app/templates/phase4.html`
- Create: `tests/test_phase4.py`
- Modify: `app/__init__.py`

**Interfaces:**
- Produces: `GET /group?album_id=...` → phase4.html with photo stream + divider zones
- Produces: `POST /group/divider` body `{"album_id", "after_asset_id"}` → `{"ok": true}`
- Produces: `POST /group/remove-divider` body `{"album_id", "divider_id"}` → `{"ok": true}`
- Produces: `POST /group/label` body `{"album_id", "group_id", "label"}` → `{"ok": true}`
- Produces: `POST /group/done` body `{"album_id"}` → redirect `/write`
- Produces: `POST /group/from-note` body `{"album_id", "text"}` → `{"ok": true}` (marks write stale)

State: groups are rebuilt from divider positions each time. The state stores `dividers: [{"id": str, "after_order": int}]` and a `group_labels: {"divider_id": str}` map. On GET, groups are computed from dividers.

- [ ] **Step 1: Update state model** — add `dividers` and `group_labels` to `TripState` in `app/state.py`:

```python
@dataclass
class TripState:
    # ... existing fields ...
    dividers: list = field(default_factory=list)   # [{"id": str, "after_order": int}]
    group_labels: dict = field(default_factory=dict)  # {divider_id: label}
```

Update all fixture JSON files to include `"dividers": [], "group_labels": {}`.

Fix `Group` dataclass to add `label` field in `state.py`:

```python
@dataclass
class Group:
    id: str
    photo_ids: list = field(default_factory=list)
    entry_type: str = "journal"
    label: str = ""          # ← add this
    title: str = ""
    # ... rest unchanged

## Task 10: Phase 6 — Export

**Files:**

- Create: `tests/test_phase6.py`
- Modify: `app/__init__.py`

**Interfaces:**
- Produces: `GET /export?album_id=...` → phase6.html with summary
- Produces: `POST /export/run` body `{"album_id", "overwrite_ids": [...]}` → `{"ok": true, "results": [...]}`

Export logic per group (status=written only):
1. Slugify title: lowercase, spaces→hyphens, strip non-alphanumeric except hyphens
2. Compute dest path
3. If dest exists and group.id not in overwrite_ids: return `{"needs_overwrite": true, "group_id": ...}`
4. Download originals from Immich; save as `photo-N.ext`
5. Write `entry.md` or `story.md` with frontmatter

## Self-Review Checklist

After writing the plan, verify:

**Spec coverage:**
- [x] Album selection (Phase 1) with resume/start-over — Task 5
- [x] Triage with J/S/X keyboard shortcuts — Task 6
- [x] Curate with remove, retag, drag reorder — Task 7
- [x] Group with entry-break dividers, labels — Task 8
- [x] Write with autosave, journal/story modes, skip — Task 9
- [x] Export with overwrite prompt, skip excluded, status=exported — Task 10
- [x] Notes panel auto-save, convert-to-entry — Task 4 (notes.py) + Task 9 (inline display)
- [x] Back-navigation + stale propagation — Task 4 (nav.py)
- [x] Dismiss stale banner — Task 4 (nav.py dismiss-stale route)
- [x] Atomic state writes — Task 2 (state.py)
- [x] Hard refresh safety — Task 2 + Task 11 (test)
- [x] Photo proxy server-side — Task 3 (proxy.py)
- [x] Docker UID/GID — Task 1 (docker-compose.yml)
- [x] Immich unreachable error banner — Task 5 (albums.py + phase1.html)
- [x] Download failure per-asset logging — Task 10 (export.py)
- [x] Export idempotency (overwrite prompt) — Task 10
- [x] Notes auto-save indicator — Task 4 (app.js + base.html)
- [x] No cascade to exported entries — Task 4 (nav.py), Task 10 (immutable status), Task 11 (test)
- [x] Playwright tests per phase — Tasks 5–11
- [x] Mock Immich server — Task 1 (conftest.py)
- [x] State fixture per phase — Task 1 (fixtures/)
- [x] Docker service + Dockerfile — Task 1
- [x] .gitignore for state files — Task 1
- [x] Multi-album merge + deduplication — Task 5 (albums.py /select)

**Type consistency:**
- `load_state(album_id, app)` / `save_state(state, app)` — consistent across all tasks
- `ImmichClient(base_url, api_key)` — consistent Tasks 3, 5, 10
- `Group.status` values: `draft / written / skipped / exported` — consistent Tasks 2, 9, 10
- `TripState.dividers` / `group_labels` added in Task 8 Step 1 — fixture files updated in same step
- `Group.label` field added Task 8 Step 4 — used in Task 8 `_build_groups`

**Placeholder scan:** No TBDs or "implement later" found.

**Note on Task 8:** The `Group` dataclass in Task 8 Step 4 adds a `label` field. This is a non-breaking addition since all other tasks either create Groups without `label` (defaults to `""`) or read groups without depending on `label`. The fixture files Phase 5/6 already have full group objects — add `"label": ""` to their group entries when implementing Task 8.
