Add municipality and coordinate search, and a map target selector
Puts the controls that change what the map is looking at over the map itself, where they act, and gives them something to search. Search is one field, not two. A string either parses as coordinates or it does not, and the answer is obvious from the text, so making the user declare up front which kind of thing they are looking for would be asking them to do the program's job. Coordinates accept decimal and degrees-minutes-seconds, comma or space separated, with hemisphere letters — including the Italian O for ovest, because someone reading an Italian map will type it and silently reading it as east would put them the wrong side of Greenwich. The 1180 Piedmont municipalities are bundled rather than geocoded online. The app is region-scoped, so a list of one region's towns is small enough to ship (100 KB) and beats a geocoder on every axis that matters: instant, offline, no API key, no rate limit, and it cannot return a result somewhere the app has no radar for. Matching folds accents, so "aglie" finds "Agliè", and prefix matches outrank substring ones — typing "tor" should surface Torino, not the first alphabetical name that happens to contain those letters. tool/generate_places.py derives the list from Istat boundary shapefiles (CC BY 4.0). Two properties of that file cost time and are now written down: the geometry is UTM 32N rather than degrees, and the DBF is UTF-8 despite one bilingual Friulian record that makes strict cp1252 fail. A terminal renders utf-8 and latin-1 output identically, so the encoding cannot be settled by looking at printed text — it took dumping codepoints. A guard in the generator and a test against the shipped asset both check for mojibake now, and the guard caught a real mistake the moment it was written. The target selector switches between following the device, a saved place, and the whole region, and the selection doubles as what the app reopens on: "the place I marked" and "what I see when I open the app" are one idea to the person using it. Dragging the map while it is following stops the camera chasing them but leaves that preference alone, because looking somewhere else now is not the same as changing their mind about next launch. The position marker and the following are MapLibre's own, driven by onCameraTrackingDismissed, so there is no second location stream to keep in step with the map. A test asserts that all 1180 municipalities fall inside the region bounds, which is what actually validates the UTM-to-degrees conversion end to end. Verified on the emulator: the dropdown lists follow, region and both saved places; "aglie" finds Agliè; "44.3841 7.5426" offers the coordinate jump and lands on Cuneo at town-reading zoom; selecting follow moves the map to the device position with the blue dot on it and changes the recentre button to match.

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.

Add the radar data layer with the offline mock adapter
Introduces the RadarSource seam and the manifest it speaks, plus the demo frames that make the app runnable with no network and no credentials. MockRadarSource is a real adapter rather than test scaffolding, and that is what makes the rest of milestone 3 testable: the timeline, prefetching, cache eviction and every degraded path can be exercised offline because the demo frames parse the same manifest document the Python worker will publish. Its assets come from tool/generate_mock_frames.py — committed so the app runs from a clone, generated by a script so they can be regenerated instead of hand-edited. Twenty-four 512x512 frames total 108 KB, and the generator is pure standard library so nobody needs Pillow to build the app. The manifest parser rejects three things that would otherwise fail silently and look plausible: - A CRS other than EPSG:3857. The map overlays each PNG on a lat/lng quad, which only lines up if the image is already in Web Mercator; anything else renders visibly skewed with no error to explain why. - A missing attribution. The frames are a derived product of CC BY-SA data, so the credit has to travel with them rather than be remembered at render time. - Legend stops that do not ascend, which would silently mislabel intensities. The legend travels in the manifest rather than living as a constant here, because the worker chose those colours when it rendered the PNGs and a local copy could drift. RadarLegend.colorFor returns null below the lowest stop: "no precipitation" has to be transparent, not the first colour of the ramp, or a dry region renders as drizzle everywhere. Every failure reaches the caller as a single RadarUnavailableException regardless of cause, because the app's response is the same in all of them — hold the last good frame and say how old it is — and branching on cause would only invite divergence. ArpaRadarSource is a stub whose every method throws. It is named by the region config as unavailable and must fail loudly: quietly serving something else would misreport where the data came from. Verified: analyze clean, 95 tests passing, including a check that every frame the manifest lists exists and is a real PNG, and that its bbox matches the region config.

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.
