Narrow scope to radar, and put the app on a real OpenStreetMap base map
Drops forecasts, lightning, the home-screen widget and advertising. What remains is radar on a map, the official ARPA alert bulletin, and rain notifications. The base map is now OpenFreeMap's Positron style: real OpenStreetMap vector tiles with no API key, no registration, no request limits and commercial use permitted. Every other free tier — MapTiler, Stadia, Jawg, Thunderforest — needs a key, which is a secret to manage, a quota to outgrow and a signup to complete before anyone can build the project, and the map is the one thing the app cannot work without. Positron rather than Liberty or Bright because the radar overlay has to be the loudest thing on screen, and a desaturated grey base is built to sit under data. Its style JSON carries no `attribution` field, so MapLibre displays no credits by itself. The app renders them from the region config instead: the two mandatory credits, OpenStreetMap and OpenMapTiles, go in the always-visible bar, and OpenFreeMap's own credit — optional by their terms — is listed on the Sources screen with the rest. The bundled offline style is still reachable with MAP_STYLE_URL=offline, and still claims no base map attribution, because crediting OpenStreetMap while showing it would be a false claim. Radar-DPC stays the source. ARPA Piemonte's own radar remains a disabled stub for two reasons that belong to the project owner, not to the code: the real-time access link is only issued by email, and the open-data page states the data is "gratuiti" and nothing else. Free of charge is not a licence, and rendering those volumes into frames served from a CDN is redistribution. Both questions go in the same email. An earlier draft of the docs recorded ARPA radar as CC BY 4.0; the source page does not support that, so the claim is removed rather than carried forward. The documentation is updated throughout rather than annotated: CLAUDE.md gains an explicit scope boundary, data-sources drops MET Norway and ISTAT and gains the base map, licenses records that free of charge is not a licence, privacy loses the whole advertising section, and the roadmap is renumbered so the backend worker is next — until it exists, DpcRadarSource has nothing to read. licenses.md keeps Open-Meteo and Blitzortung listed as excluded even though the features that would have used them are gone: both are non-commercial-only, ads are a plausible future, and neither should be adopted on the grounds that there are none today. Verified: analyze clean, 130 tests passing, and on the emulator the radar overlay sits correctly over Piedmont on real OSM tiles with Turin, Milan and Genoa labelled, the age reads "Aggiornato 4 minuti fa", and the Sources screen lists all five credits with their licences.

Animate the radar timeline with a double-buffered overlay
Completes milestone 3: frames render over the map, play as a loop, and can be scrubbed, with the legend drawn from the manifest rather than a constant that could drift from what the worker actually rendered. The overlay alternates two MapLibre image sources. Updating one source in place flickers, because the layer briefly shows a half-written texture; adding every frame as its own layer avoids that but pins them all in GPU memory, and twenty 512x512 RGBA frames is about 80 MB. Two buffers cost the same whether the timeline holds six frames or sixty. Platform-channel work is serialised because `show` is called faster than the round trip completes during playback, and overlapping updates would swap visibility out of order and strobe. Prefetching loads a window around the playhead, nearest first and forward before backward, since playback moves forward and that frame is needed soonest. `FrameCache` is byte-budgeted rather than entry-counted because frame size tracks how much precipitation is on screen, and it evicts by distance from the playhead: plain LRU would keep frames the prefetcher touched a moment ago even after the playhead moved to the far end of the timeline. Also adds DpcRadarSource, which reads published frames from our CDN and never from the DPC API. Without it, the `dpc` adapter would have had to fall back to mock, putting demo frames on screen under the label of live data — exactly the confusion the adapter split exists to prevent. It now fails naming the missing setting instead. Running it on the emulator caught three things the tests had not: - The notifier wrote to `state` from inside `build()`, which Riverpod rejects as an uninitialised provider. That broke startup, not just tests. - Eight-month-old demo frames rendered as "Aggiornato 342535 minuti fa". The age formatter now steps up to hours and days. - Demo mode sat permanently behind a stale-data warning and so never showed the working state it exists to demonstrate. MockRadarSource now shifts the bundled timestamps onto the present, leaving images, order and spacing untouched, so the timeline behaves exactly as it would on live data. Corrects docs/stack-decisions.md, which described a disk cache that was not built: mock frames already live in the asset bundle, so a disk layer belongs with the network adapter where it would save a real request. Verified: analyze clean, 129 tests passing, and on the emulator the loop advances, wraps, and reports "Aggiornato ora". Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

Fit the map to the region and keep attribution clear of the gesture bar
Running the app on an emulator for the first time showed two problems that the unit tests could not have caught, because both are about what the pixels actually do. The configured initial zoom of 7.2 puts the viewport entirely inside the region on a 411dp-wide screen, so the map rendered as a flat expanse of fill colour with no outline, border or reference point anywhere in view — it read as a failure to load. A single zoom number cannot frame a region on both a phone and a tablet, so the camera now fits the region bounds once the map is ready, which is correct at any screen size. The configured zoom stays as the starting position before the fit. The attribution bar sat behind the system gesture pill. A credit that is covered by the navigation bar is a credit that is not being displayed, which is the thing ODbL and CC BY-SA actually require, so it now sits inside a SafeArea. Also records how to run and screenshot the app on the `nuvolari` AVD, and notes the pre-existing broken `pixel_7_-_api_35` AVD that is holding 4.8 GB. Verified on the emulator: the region outline is framed with margin, the attribution bar is clear of the pill, and the Sources screen shows the disclaimer, all four credits with their licences, the "no licence stated" line for ARPA and the share-alike note.

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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

Scaffold the Flutter app with Italian l10n and region configuration
Creates the app skeleton and the seam everything else in the project hangs off: region-specific data lives in an asset file, not in code, so adding a region later is a new JSON file rather than a refactor. Notable choices: - applicationId and namespace are it.nuvolari.app rather than the doubled it.nuvolari.nuvolari that `flutter create` produces, with the Kotlin package and the iOS bundle identifiers moved to match. - SDK levels are pinned instead of inherited from `flutter.*`. Google Play requires API 36, and that is a release blocker rather than something to let a Flutter upgrade change silently. minSdk 24 is the highest floor the planned dependencies impose. - Riverpod and Dio-free for now, no code generation: see docs/stack-decisions.md. - Italian is the l10n source language, so app_it.arb is the template rather than a translation of an English original. The region parser rejects rather than repairs. An inverted bounding box, a map centre outside its own bounds, an unknown adapter name, a duplicate zone code or an empty attribution list all throw with the offending field named. Each of those would otherwise fail silently and visibly wrong: a swapped latitude and longitude renders the radar in the wrong place, an unknown adapter falling back to mock would show demo frames where live data was expected, and a missing attribution is a licence violation rather than a cosmetic gap. Tests run against the asset that actually ships and against a captured copy of the live ARPA CAP feed, so the eleven zone codes in the config are checked against the eleven the feed really emits rather than against a list retyped from documentation. Verified: dart format clean, flutter analyze 0 issues, 50 tests passing, flutter build appbundle --debug produces an AAB with applicationId it.nuvolari.app, minSdk 24, targetSdk 36.

Add monorepo scaffolding and project documentation
Sets up the Nuvolari monorepo layout (app/, backend/, docs/, tool/) with the groundwork that does not depend on the Flutter toolchain: gitignore covering Flutter, Python and every secret file shape; env.example.json as the template for --dart-define-from-file; a verification script that skips stages whose target does not exist yet so it is runnable from day one; and a CI workflow in GitHub Actions syntax so it runs unchanged on Gitea or GitHub. The documentation records facts verified against the live services rather than restated from the brief. Two of them change the design: - DPC VMI rasters are 1200x1400 Float32 on a 1 km grid in a custom projection centred on Italy, not EPSG:4326 or EPSG:3857, and their GeoKeys are internally inconsistent. Reprojection is mandatory and the source CRS must be read from each file rather than hardcoded. - The ARPA CAP feed carries six level values, not four: BIANCO for the avalanche scale out of season and "-" for no data. Collapsing either into VERDE would report "no alert" where the bulletin reports "not assessed". Also documents why the frames we publish inherit CC BY-SA from the DPC source, and why rain notifications subscribe to cell topics from the device so no user location ever reaches a server.
