Alby96andClaude Opus 5 7c0a1bd180 Disable emulator quickboot snapshots

The AVD's quickboot snapshot had grown to 2.6 GB, which took this machine down
to 1.4 GB free. Saving a minute of boot time is not worth that here, so cold
boot is now the default and the snapshot directory is gone.

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.

Verified on an emulator (nuvolari, API 36.1, x86_64, GPU host). Running it caught two things the unit tests could not: the configured initial zoom put the viewport entirely inside the region so the map read as a blank expanse, and the attribution bar sat behind the system gesture pill. Both fixed — the camera now fits the region bounds at runtime, which works on any screen size, and the bar is inside a SafeArea.

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

Needed for	Item
M2 (quality)	MapTiler API key — until then the local fallback style is used
M5	AdMob App ID and ad unit IDs
M6	Firebase project and `google-services.json`
M8	VPS / object storage endpoint and credentials
M9	Play Console account and upload keystore

Verifying on the emulator

An AVD named nuvolari is set up on this machine: API 36.1, google_apis, x86_64, GPU passthrough to the host. It uses a 2 GB data partition and no SD card because disk is tight, and quickboot snapshots are disabled — they cost 2.6 GB to save a few seconds of boot, which is the wrong trade here. Expect a cold boot of a minute or so.

# Boot it
"$ANDROID_HOME/emulator/emulator" -avd nuvolari -no-audio -no-boot-anim -gpu host

# Build, install, launch
cd app
flutter build apk --debug
adb install -r build/app/outputs/flutter-apk/app-debug.apk
adb shell am start -n it.nuvolari.app/.MainActivity

# Capture what it looks like
adb exec-out screencap -p > screen.png

flutter run -d emulator-5554 works too and gives hot reload; the steps above are what a non-interactive session uses.

An unrelated AVD, pixel_7_-_api_35, is present but broken — its system image (android-35/google_apis_playstore) is not installed, so it cannot boot. It occupies about 4.8 GB. It predates this project and has been left alone.
