Alby96andClaude Opus 5 d84095b5a8 Add the region map, permanent attribution and the Sources screen

Puts a MapLibre map on screen framed on the region, with the credit
obligations that come with showing third-party data satisfied structurally
rather than by remembering to add a label.

The base map style comes from MAP_STYLE_URL, and with no key configured the
app generates a fallback style from the region's own bounding box: a flat
background and the extent outline, no network sources at all. That keeps a
fresh clone runnable offline without pulling in a boundary dataset that would
carry its own licence, and it deliberately looks like a placeholder so it is
not mistaken for a finished map.

Attribution is driven by what is actually rendered. The bar lists the credits
for the active sources only, because crediting OpenStreetMap while showing the
fallback style would be a false attribution, and it says plainly when no base
map is configured. It sits below the map rather than floating over it so no
map control or gesture overlay can occlude a credit that the ODbL and CC BY-SA
terms require to be visible.

The Sources screen leads with the independence disclaimer, before the sources
it qualifies, so a reader who stops after the first screenful has still seen
it. Sources with no stated licence — ARPA publishes none for the alert
bulletin — say so explicitly rather than being shown bare or given an invented
one. A separate note explains that the rendered radar frames inherit CC BY-SA
from the DPC source data.

Also declares the INTERNET permission in the main manifest: Flutter injects it
into the debug and profile manifests only, so a release build would otherwise
fail every request on device.

Verified: analyze clean, 66 tests passing, appbundle builds with the native
MapLibre plugin. Not verified visually — this machine has no Android device or
emulator image, so nobody has watched the map render.

Roadmap

Each milestone ends with tool/verify.ps1 green and one commit. A milestone is not done until its acceptance criteria hold.

Legend: ✅ done · 🔨 in progress · ⛔ blocked on credentials from the project owner

M0 — Toolchain and repository hygiene ✅

Flutter 3.47.3 stable, Android SDK (platform-tools, platform 36, build-tools 36.0.0), JDK 21, environment variables. Commit the removal of the old Xamarin skeleton.

Accepts when: flutter doctor -v reports no blocking Android toolchain error and git status is clean.

Done. flutter doctor -v reports "No issues found!". Installed: Flutter 3.47.3 at C:\src\flutter (telemetry disabled), Android SDK at C:\Android\Sdk with platform 36, build-tools 36.0.0, platform-tools and all licences accepted, and JAVA_HOME pointing at the JDK 21 a previous Visual Studio install had already left on the machine.

M1 — Scaffold, Italian l10n, region config, CI ✅

flutter create with applicationId it.nuvolari.app; flutter_localizations + intl with app_it.arb as template and no hardcoded UI strings; RegionConfig loaded from assets/regions/piemonte.json with parsing tests; .gitignore, env.example.json, tool/verify.ps1, .gitea/workflows/ci.yml.

Accepts when: flutter analyze reports 0 issues, flutter test passes, flutter build appbundle --debug succeeds.

Done. All four stages green; the AAB carries applicationId it.nuvolari.app, minSdk 24, targetSdk 36. 50 tests, including assertions against the shipped Piemonte asset and a captured copy of the live ARPA CAP feed.

The Gitea instance may have no Actions runner. The workflow file is written to be GitHub-Actions compatible, but tool/verify.ps1 is the verification that must pass.

M2 — Map, attribution, Sources screen ✅

MapLibre with the style from MAP_STYLE_URL, falling back to a local minimal style. Permanent OSM/ODbL attribution. Sources / Licenses / Disclaimer screen covering Radar-DPC (CC BY-SA), MET Norway, ARPA, OSM, with the explicit "not an official app" disclaimer.

Accepts when: the map opens centred on Piedmont, attribution is visible at all times, and the Sources screen is reachable and complete.

Done, with one gap. The fallback style is generated from the region bounding box rather than loaded from an asset, so it needs no third-party boundary dataset and no network. The attribution bar lists only the sources actually rendered — crediting OpenStreetMap while showing the fallback would be a false attribution — and sits below the map rather than floating over it so no map control can occlude it.

Not visually verified. This machine has no Android device and no emulator image, so the map has been proven to build and its logic unit-tested, but nobody has watched it render. Connect a phone over USB or install an emulator system image before trusting the visual result.

M3 — Animation and timeline 🔨

RadarSource with MockRadarSource (synthetic frames in assets) and DpcRadarSource. Timeline scrubber, play/pause, adjacent-frame prefetch, FrameCache LRU, animation suspended in background, graceful degradation with a data-age banner.

Accepts when: animation runs smoothly in demo mode with the network off, and prefetch, LRU eviction and the fallback paths are covered by tests.

M4 — Forecast

MetNoForecastSource with the mandatory identifying User-Agent, honouring Expires and If-Modified-Since. IconIt2Source as a flagged fallback. Hourly and daily views.

Accepts when: a forecast renders for a Piedmont location, caching respects the response headers, and fixture-based tests pass.

UMP consent form before any ad request; non-personalised ads when consent is declined. Anchored adaptive banner — never over the map, never an interstitial during animation. Test ad unit IDs only until real ones are supplied.

Blocked on: AdMob App ID and ad unit IDs.

M6 — Rain notifications and alerts ⛔

ArpaCapAlertSource reading the CAP feed through the backend; zones Piem-A…Piem-M with levels shown verbatim and a link to the official bulletin. Rain notifications via FCM topics per geographic cell, subscribed from the device.

Blocked on: Firebase project and google-services.json.

Glance widget showing the latest frame and the next rain, refreshed by WorkManager.

Accepts when: the widget renders a real frame on the home screen and updates.

M8 — Backend worker ⛔

dpc_client (with the origin header), crop (bbox + reproject to EPSG:3857), palette (dBZ colormap, legend exported into the manifest), render (RGBA PNG, transparent below threshold), manifest, and publisher/ with LocalPublisher and S3Publisher. WebSocket trigger with cron fallback. pysteps nowcast present but disabled behind a flag.

Accepts when: python -m pytest passes and one full run produces PNGs plus a manifest.json that the app consumes from a local server.

Blocked on (publishing only): VPS / object storage endpoint and credentials. Development proceeds against LocalPublisher.

M9 — Play Store release preparation ⛔

Signing config reading key.properties, release AAB, target API 36, privacy policy draft, store listing copy, Data safety draft, prominent disclosure for location.

Blocked on: upload keystore and Play Console account.

Pending inputs from the project owner

M5	AdMob App ID and ad unit IDs
M6	Firebase project and `google-services.json`
