# Changelog

## v0.4.0 — 2026-09-17 08:22
- Self-hosted all OpenFreeMap map-styling assets (tiles stay remote): new `scripts/download-map-assets.mjs` fetches the 5 OFM styles with a browser UA, rewrites each via `rewriteStyle`, and extracts the font/sprite tarballs into `public/` — committed so the image is self-contained: `public/styles/{liberty,bright,positron,dark,fiord}.json` (0.15 MB), `public/fonts/Noto Sans {Regular,Italic,Bold}/*.pbf` (768 files, 99.76 MB — the font payload), `public/sprites/ofm{.json,.png,@2x.json,@2x.png}` (0.21 MB); total public/ = 100.13 MB
- New shared module `lib/mapStyles.ts`: `STYLES` registry (5 ids + labels), `DEFAULT_STYLE_ID = 'fiord'`, and pure `rewriteStyle()` — glyphs `https://tiles.openfreemap.org/fonts/{fontstack}/{range}.pbf` → `/fonts/{fontstack}/{range}.pbf`, sprite `https://tiles.openfreemap.org/sprites/ofm_f384/ofm` → `/sprites/ofm`; the vector tile url (`/planet`) and ne2_shaded raster tiles (`/natural_earth/ne2sr/...`) are left remote; every source lacking an attribution gets `"© OpenStreetMap contributors © OpenFreeMap"` (OFM styles ship none; ODbL requires visible OSM credit)
- `components/Map.tsx`: map now loads the local `/styles/fiord.json` by default; new top-bar style switcher (`<select data-testid="style-switch">`, subtle styling in `app/globals.css`) listing all 5 styles, persisted to localStorage key `flight-ops-style`; SSR-safe — state initializes to `DEFAULT_STYLE_ID` and the saved choice is read/applied only in a post-mount effect (no localStorage reads during render/hydration)
- `components/Map.tsx`: airports layer now survives style switches — `/api/airports` is fetched at most once per page life (promise cached in a ref; count set exactly once), and an idempotent `ensureAirportsLayer()` re-adds the source+layer if missing on EVERY `styledata` event (initial load AND after each `setStyle`, which wipes sources/layers not in the new style); the click→popup handler is re-wired with off+on using a stable reference since MapLibre layer-scoped listeners survive setStyle and would otherwise duplicate
- `Dockerfile`: runtime stage now copies `public/` from the build stage (`COPY --from=build /app/public ./public`) so `next start` serves the self-hosted assets; `.dockerignore` already lets public/ through
- Tests: new unit suite `lib/mapStyles.test.ts` (registry shape, fiord default, rewriteStyle against an inline OFM fixture — local glyphs/sprite, remote tiles preserved, attribution added/preserved, input not mutated); `e2e/map.spec.ts`: openfreemap mock simplified to abort ALL requests from that host (only tiles remain there), new test asserting the switcher has 5 options with Fiord default, switching changes the applied style's layer set AND the airports layer re-renders after the switch + exactly one popup on marker click (guards the setStyle-wipes-layers and duplicate-listener regressions), plus a reload-persistence test for the localStorage restore path
- Verified: unit suite 16/16; `tsc --noEmit` clean; e2e suite 6/6 green against the rebuilt compose instance (all styles/fonts/sprites served locally, fiord default, switch + persistence verified in a real browser)

## v0.3.1 — 2026-09-17 06:35
- Header now shows the app version between the "Flight Ops" title and the airport count (`<small>v{version}</small>` in `components/Map.tsx`), sourced dynamically from `package.json` via a JSON import — future version bumps show up automatically with no code change; subtle 11px muted style added to `app/globals.css`
- Tests: new unit suite `components/version.test.ts` (valid semver in package.json + guard that the header sources the version from package.json rather than hardcoding it); `e2e/map.spec.ts`: new test asserting the header shows `v{version}` with the expected value read from `package.json` at test time, so it stays in sync automatically
- Verified: unit suite 10/10; `tsc --noEmit` clean; e2e suite 4/4 green against the rebuilt compose instance

## v0.3.0 — 2026-09-17 00:32
- Removed the zoom-driven camera tilt (`lib/camera.ts` pitch curve + the map `move` handler): the map is now always flat/top-down with standard pan/zoom only; deleted `lib/camera.ts` and its unit tests
- Removed terrain: no more DEM raster source / `map.setTerrain`, and the `?terrain=0` / `NEXT_PUBLIC_TERRAIN` toggles are gone — pure 2D view, no 3D elements
- MAX_ZOOM 14 → 11: at European latitudes (~52°N) z11 ≈ 47 m/px, so the viewport spans ~90–135 km across a typical desktop width (≈100 km on screen); street-level zoom had no gameplay value
- `e2e/map.spec.ts`: APP_URL is now `/` (terrain flag removed), MAX_ZOOM mirror updated to 11; PLAN.md map section updated to flat-2D-only
- Verified: unit suite 8/8; `tsc --noEmit` clean; e2e suite 3/3 green against the rebuilt compose instance (flat view, wheel zoom clamped to [3, 11])

## v0.2.9 — 2026-09-17 00:21
- `data/airports_eu.csv`: multi-airport metro areas reduced to one dot each on the map — Paris→CDG, London→LHR, Moscow→SVO, Milan→MXP, Istanbul→IST, Warsaw→WAW, Brussels→BRU (Rhine-Ruhr keeps both DUS and CGN as distinct cities); dropped 18 satellite airports incl. Orly, Gatwick, Luton, Stansted, Domodedovo, Vnukovo, Zhukovsky, Linate, Caravaggio, Atatürk, Modlin, Charleroi, Weeze, Prestwick, Treviso, Ciampino, Băneasa — 260 → 242 rows; `/api/airports` and the circle layer pick it up with no code changes
- Verified: unit suite 8/8; `tsc --noEmit` clean; e2e suite 3/3 green against the rebuilt compose instance (`/api/airports` serves 242 features)

## v0.2.8 — 2026-09-16 23:53
- `data/airports_eu.csv`: reduced the dataset to only `large_airport` rows (dropped all 731 medium_airport + 54 seaplane_base) — the map now shows just the 260 biggest EU airports; `/api/airports` and the circle layer pick it up with no code changes
- `e2e/map.spec.ts`: marker-click test repointed from ESSV Visby Airport (a medium_airport, now removed) to UKBB Boryspil International Airport — with only large_airport rows left it is the most isolated marker inside the initial zoom-4 viewport: its nearest surviving airport is Chişinău (LUKK), ~126 px away at the initial zoom (Kyiv Zhuliany, geographically closer, was a medium and got cut)
- Verified: unit suite 12/12; `tsc --noEmit` clean; e2e suite 3/3 green against the rebuilt compose instance (`/api/airports` serves 260 features)

## v0.2.7 — 2026-09-16 23:39
- `data/airports_eu.csv`: removed all 6400 `small_airport` rows from the OurAirports EU export — the map now shows only the 1045 bigger airports (260 large + 731 medium + 54 seaplane_base); `/api/airports` and the circle layer pick it up with no code changes
- `e2e/map.spec.ts`: marker-click test repointed from EKRN Bornholm Airport (a small_airport, now removed) to ESSV Visby Airport on Gotland — its nearest remaining airport is Stockholm Skavsta across the Baltic Sea (~59 px away at the initial zoom), so its marker cannot be overlapped by a neighbouring circle
- Verified: unit suite 12/12; e2e suite 3/3 green against the rebuilt compose instance (`/api/airports` serves 1045 features)

## v0.2.6 — 2026-09-16 22:41
- `Dockerfile`: install stages switched from npm to bun (`oven/bun:1.4.2-alpine`, `bun install --frozen-lockfile`); `package-lock.json` replaced by `bun.lock`; no BuildKit `type=cache` mounts — they don't persist across builds on this daemon, and bun install is fast enough (~3 s cold) that cross-build caching isn't worth it
- `Dockerfile`: new `prod-deps` stage (`bun install --production`) so the runtime image carries prod-only `node_modules` — devDeps (typescript, vitest, @types) are no longer shipped; build and runtime stages otherwise unchanged (still node:22-alpine, full `.next`, no standalone output)
- `.dockerignore`: excludes docs/deployment files (`*.md`, `Dockerfile*`, `docker-compose*`) from the build context so changelog-only commits don't invalidate the COPY layer and re-run `next build`
- Verified: full cold build 77 s → 58 s; e2e suite 3/3 green against the rebuilt compose instance

## v0.2.5 — 2026-09-16 21:22
- `AGENTS.md`: new "E2E tests (mandatory)" section codifies the e2e workflow — the compose instance behind Traefik (`https://flight.dev.kkhost.pl`) is always the app under test, never a local `next dev` on :3000; deploy current code first with `docker compose up -d --build`; browsers run through the shared remote Playwright server at `192.168.1.4:3000`, and plain `npx playwright test` handles deploy + readiness + remote connect
- `playwright.config.ts`: dropped the `E2E_LOCAL=1` local-dev path accordingly — no more local :3000 dev instance for e2e; the default (and only) mode is browsers on the shared remote Playwright server against the prod build behind Traefik, with `webServer` running `docker compose up -d --build`; `E2E_REMOTE=1` and explicit `PW_TEST_CONNECT_WS_ENDPOINT`/`E2E_BASE_URL` overrides are unchanged

## v0.2.4 — 2026-09-16 21:06
- `playwright.config.ts`: default e2e mode now targets the prod build behind Traefik (`https://flight.dev.kkhost.pl`) — `baseURL` defaults to that URL and `webServer` runs `docker compose up -d --build` (300 s timeout) instead of `npm run dev`, because `next dev` does not render for non-loopback clients: Turbopack's HMR WebSocket fails from the remote browsers, so the page loads blank
- `E2E_LOCAL=1` keeps the local iteration path (browsers on this box, `webServer` auto-starts `npm run dev`, baseURL `localhost:3000`) as a fallback when the proxy or compose stack is down; `E2E_REMOTE=1` and explicit `PW_TEST_CONNECT_WS_ENDPOINT`/`E2E_BASE_URL` overrides are unchanged

## v0.2.3 — 2026-09-16 20:30
- `playwright.config.ts`: e2e now launches browsers on the shared remote Playwright server (Docker, `ws://192.168.1.4:3000/`) by default — when no env vars are set it exports `PW_TEST_CONNECT_WS_ENDPOINT` pointing at that box; in this mode `baseURL` defaults to this box's LAN IP (`http://192.168.1.26:3000`) because pages load from the remote browser's perspective, while the local `webServer` still auto-starts `npm run dev`
- `E2E_LOCAL=1` restores fully-local runs (browsers on this box, `localhost:3000` baseURL) as a fallback when the remote server is down; `E2E_REMOTE=1` keeps its previous behavior for runners on other machines — skips `webServer` entirely and pairs with `E2E_BASE_URL`; an explicit `PW_TEST_CONNECT_WS_ENDPOINT` always wins over the default

## v0.2.2 — 2026-09-16 20:05
- `playwright.config.ts`: e2e suite can now run on a different machine than the app — with `E2E_REMOTE=1` the local `webServer` block is skipped entirely and `baseURL` defaults to `http://flight.dev.kkhost.pl`; `E2E_BASE_URL` overrides `baseURL` in both modes; with no env vars set behavior is unchanged (local `webServer` auto-starts `npm run dev`)

## v0.2.1 — 2026-09-16 19:49
- Clamp map zoom to the useful gameplay range: `minZoom: 3` / `maxZoom: 14` on the MapLibre options in `components/Map.tsx` (exported as `MIN_ZOOM`/`MAX_ZOOM`) — wheel travel from the Europe overview is now ~10 levels instead of ~16, and street-level zoom past the z12 pitch transition no longer exists
- e2e: new test that wheels well past both limits via `page.mouse.wheel` (basemap tile fetches blocked for speed/determinism; clamping is pure camera behavior) and asserts via `expect.poll` on the map instance that `getZoom()` settles at 14 / 3, i.e. clamped within [3, 14]

## v0.2.0 — 2026-09-16 18:32
- Docker deployment: multi-stage `Dockerfile` (node:22-alpine; deps → build → runtime) running `next start` on port 3000; no `output: 'standalone'` — the runtime stage keeps full `node_modules` because `/api/mlworker/[file]` reads maplibre-gl dist files from disk at runtime (and `/api/airports` reads `data/*.csv`)
- `.dockerignore`: node_modules, .next, data/*.db, test-results, *.tsbuildinfo, plus .git/.env/.codenomad and the e2e harness (`@playwright/test` is a host-global install, not a project dependency — Next's build-time type check would fail on it inside the image)
- `docker-compose.yml`: single service `flight`, no published ports, joins external network `dev_net` with Traefik labels routing `Host(flight.dev.kkhost.pl)` → port 3000 (plain HTTP entrypoint `web`; TLS terminated upstream)
- Verified: container builds and runs; router registered in dev_traefik rawdata; `curl -H "Host: flight.dev.kkhost.pl" http://localhost/` → 200, `/api/airports` → 200 GeoJSON (7445 features), mlworker .mjs files served from node_modules inside the container; unit suite 12/12 and e2e suite 2/2 still green

## v0.1.0 — 2026-09-16 18:24
- Scaffolded Next.js (App Router) + TypeScript project; dev server on port 3000 (`npm run dev`)
- Full-viewport MapLibre GL map with OpenFreeMap "liberty" vector basemap (attribution included via style)
- Zoom-driven camera controller: top-down at zoom ≤ 6, smoothstep tilt to 45° pitch by zoom ≥ 12; pitch is a pure function of zoom so it never fights pan/zoom gestures
- Lite 3D terrain from AWS terrarium raster-DEM tiles (`map.setTerrain`); toggleable off via `?terrain=0` or `NEXT_PUBLIC_TERRAIN=0` (off in e2e for deterministic headless rendering)
- EU airport seed data: OurAirports CSV (official mirror at davidmegginson.github.io/ourairports-data — the legacy ourairports.com/data URL now 404s) filtered to continent=EU with types small/medium/large_airport + seaplane_base → committed as `data/airports_eu.csv` (7445 airports; heliports, closed and balloon sites excluded — rationale documented in `lib/airports.ts`)
- `GET /api/airports`: server-side CSV parse with in-memory cache, returns GeoJSON FeatureCollection (properties: name, icao, lat, lon)
- Client renders airports as a GeoJSON circle layer (no DOM markers); click → popup with name + ICAO; header shows loaded airport count (`data-testid="airport-count"`)
- MapLibre worker served from node_modules via `/api/mlworker/*` route — bundlers break the URL MapLibre derives for its worker, which silently hangs GeoJSON source updates
- Tests: vitest unit suite (CSV parse/filter, GeoJSON build, pitch curve, API handler) + self-contained Playwright e2e suite (`webServer` auto-starts `npm run dev`; page load + airport count + marker click popup)
