Give the map the whole screen and move the credits into settings
Drops the app bar, moves settings onto the map with the other controls, and takes the attribution bar off the main screen. The app bar held only the app name — which the launcher already shows — and one action, so removing it hands its height to the map rather than leaving an empty strip. The settings button joins search and recentre in the column over the map, where the rest of the controls that act on the map already live. The attribution needed checking before it could move, because it is a licence obligation rather than a layout choice. The OSMF guidelines settle it: for a browsable map the credit does not have to be permanently visible, provided "the user must still be able to find the licence information if they look for it, for example from an '(i)' button in the corner of the map or an 'About' option in a menu". Map to settings to "Fonti e licenze" is exactly that, and MapLibre's own (i) control now sits in the map's top-right corner as a second route — it had been landing underneath the new button column. Two things had to follow the bar rather than disappear with it. The radar manifest carries its own credit for the frames on screen, set by whoever published them and absent from the region config, so the Sources screen now shows it alongside the configured attributions. And the settings entry that leads there carries a subtitle saying what it holds, because "Fonti e licenze" alone does not tell a reader that this is where the licence information went. settings_screen_test asserts that entry exists and opens the screen. Removing it would be a licence breach, so it should fail the build rather than ship quietly. Verified on the emulator: no title bar, the map runs to the top with the demo notice above it, the three controls stack bottom-right without colliding with the (i), and settings shows the sources entry with its subtitle.

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.

Survey the ARPA REST APIs and correct the licence position
Scanned the two public ARPA Piemonte APIs and recorded what they actually contain, so this question does not get re-litigated from the marketing pages later. Neither needs a key, a token or a registration. This corrects something I got wrong. The docs said ARPA states no licence for its data, based on the open-data page saying only "gratuiti". The site's legal notice does state one — CC BY 4.0, commercial use explicitly permitted, credit "Fonte: Arpa Piemonte - www.arpa.piemonte.it" — and both APIs link that notice from their OpenAPI description, so anything they serve is covered. Only the radar volumes remain ambiguous, because their own page does not repeat the licence and the access link is still issued by email; both questions belong in the same message to ARPA. The survey's operative findings: - api_realtime carries 374 stations with coordinates, of which 286 have a rain gauge, spanning 74 m to 2820 m of elevation. - Its observations lag by about 4.5 hours on an hourly cadence, measured uniformly across every station sampled. That is the property that decides how it can be used: it is an observation archive with a publishing delay, not a real-time feed, and it must never sit next to 5-minute radar looking current. - Only 4 of 143 hydrometer stations publish guard and danger thresholds, and 5 publish a river name. A river-level warning built on this would be empty for 97% of stations, so that idea is recorded as rejected rather than pending. - Meteoweb is a 3.27-million-record historical archive plus a seismic catalogue: a research dataset, not app content. One thing is worth adopting: rain-gauge accumulations as ground truth for the radar. Radar infers rainfall from reflectivity aloft, gauges measure what reached the ground, and the network is densest exactly where Alpine terrain blocks the beam. It belongs behind the worker, clearly timestamped, once the worker exists. Also notes that the credit ARPA asks for is the full "Fonte: Arpa Piemonte - www.arpa.piemonte.it", not the bare name currently in the region config, to be adopted the moment any ARPA-sourced data is displayed. No code changes: nothing is integrated yet. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

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 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.
