jacobh2 76b1e712b9 Complete NextSteps roadmap: planning engine UI, calendar cluster, flexible wishes
Works through every numbered item in NextSteps260913.md section 3, plus the
three known verification issues in section 4.1.

Surface what the backend already computed:
- 3.1 render surplus_advice in PlanResults, mirroring the shortfall remedies
- 3.2 surface VacationBalance.is_assumed so assumed statutory years are visible
- 3.3 age-4 expiry given the proposed plan, via a new Age4Projection reusing
  the existing _age4_projections arithmetic (Dashboard stat verified, not rebuilt)

Calendar cluster (one pass over the holiday data):
- new GET /api/calendar/days exposing roda dagar, klamdagar and day overrides,
  paginated four years at a time
- 3.4 shade roda dagar/klamdagar, with R/K badges so colour is not the only signal
- 3.6 click-to-override behind an explicit mode toggle, leaving drag multi-select intact
- 3.7 click month/year to advance
- 3.8 per-year red-days list in Settings, statutory days plus overrides

i18n:
- 3.5 five backend-generated Swedish surfaces converted to message_key + data,
  following the tips_service pattern; old string fields replaced, not kept

Flexible wishes (3.9):
- PLANNING_ENGINE_SPEC section 10: window_mode, candidate search, cost function,
  deterministic tie-break, two-pass ordering, test matrix rows 15-24
- backend: entity, migration 006, _FULL_SCHEMA sync, repository, allocator
- frontend: season-preset toggle in WishEditor, unplaced outcome rendering

Fixes (4.1):
- pin typecheck to the local tsc rather than npx resolving a newer TypeScript
- ignore generated coverage/ and dist/ in the ESLint flat config
- fix the flaky usePlanApply test properly, with waitFor rather than a retry

Tests: backend 361 -> 404, frontend 540 -> 704. Coverage 89.47% -> 96.52% lines.

Not yet verified in a browser.

Backend — Föräldraledigplannerare

FastAPI + Python 3.14, packages managed with uv. Layered architecture (entities → repositories → services → routers) with dependency injection so the database backend (SQLite now, Postgres later) is swappable.

Setup

uv sync                 # install deps (incl. dev group)
uv run uvicorn app.main:app --reload   # run dev server on :8000
uv run pytest           # run tests with coverage
uv run ruff check .     # lint

Layout

app/
  config.py            # pydantic-settings (app config + frozen LeaveRules)
  dependencies.py      # DI factories (pick repo impl by settings.database_type)
  entities/            # plain dataclasses (domain)
  models/              # pydantic API schemas
  repositories/        # abstract interfaces
  repositories_impl/   # concrete impls per backend (sqlite/, postgres/)
  services/            # business logic
  routers/             # FastAPI routes
  db/connection.py     # connection + (dev) schema bootstrap
  utils/               # errors, logger

Reference vertical slice

VacationDays is implemented end-to-end (entity → schema → repo interface → SQLite impl → service → router → tests). Copy this slice when adding a new entity. See JUNIOR_ONBOARDING.md in the repo root for task-by-task guidance.

The inline schema in db/connection.py exists only so dev/tests are self-contained. Production schema is owned by Alembic migrations (a senior task).
