Raw Blame History

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

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

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

  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 7: Create tests/conftest.py

        shutil.copy(src, dst)
        return data["album_id"]
    return _seed

Step 8: Create tests/fixtures/phase2_state.json (album selected, triage not started)

{
  "album_id": "album-1",
  "album_name": "Central Asia 2023",
  "grav_trip_slug": "central-asia-2023",
  "phase": "triage",
  "phases_completed": [],
  "phase_stale": [],
  "photos": [
    {"id": "asset-1", "original_filename": "IMG_001.jpg",
     "local_datetime": "2023-09-05T09:03:00", "tag": "untagged", "order": 0},
    {"id": "asset-2", "original_filename": "IMG_002.jpg",
     "local_datetime": "2023-09-05T14:30:00", "tag": "untagged", "order": 1},
    {"id": "asset-3", "original_filename": "IMG_003.jpg",
     "local_datetime": "2023-09-06T10:00:00", "tag": "untagged", "order": 2}
  ],
  "groups": [],
  "notes": ""
}

Step 9: Create tests/fixtures/phase3_state.json (all photos tagged)

{
  "album_id": "album-1",
  "album_name": "Central Asia 2023",
  "grav_trip_slug": "central-asia-2023",
  "phase": "curate",
  "phases_completed": ["triage"],
  "phase_stale": [],
  "photos": [
    {"id": "asset-1", "original_filename": "IMG_001.jpg",
     "local_datetime": "2023-09-05T09:03:00", "tag": "journal", "order": 0},
    {"id": "asset-2", "original_filename": "IMG_002.jpg",
     "local_datetime": "2023-09-05T14:30:00", "tag": "story", "order": 1},
    {"id": "asset-3", "original_filename": "IMG_003.jpg",
     "local_datetime": "2023-09-06T10:00:00", "tag": "skip", "order": 2}
  ],
  "groups": [],
  "notes": ""
}

Step 10: Create tests/fixtures/phase4_state.json (curated, ready for grouping)

{
  "album_id": "album-1",
  "album_name": "Central Asia 2023",
  "grav_trip_slug": "central-asia-2023",
  "phase": "group",
  "phases_completed": ["triage", "curate"],
  "phase_stale": [],
  "photos": [
    {"id": "asset-1", "original_filename": "IMG_001.jpg",
     "local_datetime": "2023-09-05T09:03:00", "tag": "journal", "order": 0},
    {"id": "asset-2", "original_filename": "IMG_002.jpg",
     "local_datetime": "2023-09-05T14:30:00", "tag": "story", "order": 1}
  ],
  "groups": [],
  "notes": "I remember the airport was chaos."
}

Step 11: Create tests/fixtures/phase5_state.json (groups defined, ready for writing)

{
  "album_id": "album-1",
  "album_name": "Central Asia 2023",
  "grav_trip_slug": "central-asia-2023",
  "phase": "write",
  "phases_completed": ["triage", "curate", "group"],
  "phase_stale": [],
  "photos": [
    {"id": "asset-1", "original_filename": "IMG_001.jpg",
     "local_datetime": "2023-09-05T09:03:00", "tag": "journal", "order": 0},
    {"id": "asset-2", "original_filename": "IMG_002.jpg",
     "local_datetime": "2023-09-05T14:30:00", "tag": "story", "order": 1}
  ],
  "groups": [
    {
      "id": "g1", "photo_ids": ["asset-1"], "entry_type": "journal",
      "title": "", "body": "", "location_city": "", "location_country": "",
      "date": "2023-09-05", "hero_photo_id": null, "shortcode_hints": "",
      "status": "draft"
    },
    {
      "id": "g2", "photo_ids": ["asset-2"], "entry_type": "story",
      "title": "", "body": "", "location_city": "", "location_country": "",
      "date": "2023-09-05", "hero_photo_id": null, "shortcode_hints": "",
      "status": "draft"
    }
  ],
  "notes": "I remember the airport was chaos."
}

Step 12: Create tests/fixtures/phase6_state.json (all written, ready for export)

{
  "album_id": "album-1",
  "album_name": "Central Asia 2023",
  "grav_trip_slug": "central-asia-2023",
  "phase": "export",
  "phases_completed": ["triage", "curate", "group", "write"],
  "phase_stale": [],
  "photos": [
    {"id": "asset-1", "original_filename": "IMG_001.jpg",
     "local_datetime": "2023-09-05T09:03:00", "tag": "journal", "order": 0},
    {"id": "asset-2", "original_filename": "IMG_002.jpg",
     "local_datetime": "2023-09-05T14:30:00", "tag": "story", "order": 1}
  ],
  "groups": [
    {
      "id": "g1", "photo_ids": ["asset-1"], "entry_type": "journal",
      "title": "Arrival in Almaty", "body": "Chaos at the airport.",
      "location_city": "Almaty", "location_country": "Kazakhstan",
      "date": "2023-09-05", "hero_photo_id": "asset-1", "shortcode_hints": "",
      "status": "written"
    },
    {
      "id": "g2", "photo_ids": ["asset-2"], "entry_type": "story",
      "title": "The Market", "body": "Colours everywhere.",
      "location_city": "Almaty", "location_country": "Kazakhstan",
      "date": "2023-09-05", "hero_photo_id": "asset-2", "shortcode_hints": "gallery block",
      "status": "skipped"
    }
  ],
  "notes": ""
}

Step 13: Write a smoke test

Create tests/test_smoke.py:

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

Step 14: Run smoke test

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

Expected: PASS

Step 15: Commit

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
Step 1: Write failing tests

# tests/test_state.py

    )
    save_state(state, app_ctx)
    loaded = load_state("export-test", app_ctx)
    assert loaded.groups[0].status == "exported"

Step 2: Run tests — expect FAIL (ImportError on app.state)

pytest tests/test_state.py -v

Step 3: Create app/state.py

Step 4: Run tests — expect PASS

pytest tests/test_state.py -v

Step 5: Commit

git add app/state.py tests/test_state.py
git commit -m "feat: add atomic state management (TripState, Photo, Group)"

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:

@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:

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

Step 2: Run all tests

pytest tests/ -v

Expected: all PASS. Fix any failures before committing.

Step 3: Commit

git add tests/test_crosscutting.py
git commit -m "test: add cross-cutting tests (reload safety, stale, back-nav, export immutability)"

Self-Review Checklist

After writing the plan, verify:

Spec coverage:

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