+# Beatport Charts — Design Spec
+
+- **Data:** 2026-07-14
+- **Autore:** LuZa + Claude
+- **Stato:** Approvato, pronto per implementation plan
+- **Target release:** MusicTools v1.8.0
+
+## Obiettivo
+
+Aggiungere una nuova tab all'app desktop MusicTools che permetta di:
+
+1. Scegliere un genere musicale da un elenco di ~30 generi Beatport
+2. Caricare la classifica **Top 100** ufficiale di quel genere dal sito Beatport
+3. Visualizzare i 100 brani in tabella con checkbox per scegliere quali scaricare
+4. Scaricare i brani selezionati riusando il flusso esistente Spotify search → yt-dlp
+
+Sostituisce il lavoro manuale attuale (l'utente copia/incolla la Top 100 in un file `.txt` che poi passa al downloader).
+
+## Non-goals
+
+Esplicitamente **fuori scope** in questa versione:
+
+- Preview audio dei brani (snippet Beatport sono DRM protetti)
+- Chart diverse dalla Top 100 (Hype 100, DJ Charts, weekly picks) — rinviato a v2
+- Ricerca / filtro nella tabella (100 righe si scorrono senza)
+- Refresh automatico della classifica
+- Esportazione della lista come file `.txt`
+- Auto-update della mappa dei generi (resta hardcoded, aggiornata a ogni release)
+- Beatport account / login / preferiti utente
+
+## Approccio scelto — Parse `__NEXT_DATA__`
+
+Beatport è costruito su Next.js. Ogni pagina di classifica include un tag `<script id="__NEXT_DATA__" type="application/json">…</script>` con il payload completo della pagina in JSON strutturato: id, artist, title, mix, duration, chart position, label, key, BPM. Il parser:
+
+1. `GET https://www.beatport.com/genre/<slug>/<id>/top-100` con User-Agent browser
+2. `re.search(r'<script id="__NEXT_DATA__"[^>]*>(.+?)</script>', html)` per estrarre il JSON
+3. `json.loads` + walk fino ai 100 track object
+4. Mappa in dataclass `BeatportTrack`
+
+**Vantaggi:** dati strutturati, robusto ai cambi di layout CSS, un solo GET per 100 brani.
+
+**Alternative scartate:**
+- BeautifulSoup su CSS class → i class name Next.js sono hash generati, si rompono a ogni build Beatport
+- API interna `api.beatport.com` → richiede OAuth token, User-Agent specifici, ToS espressamente vietano l'uso non autorizzato → rischio ban
+
+## Architettura
+
+### Nuovi moduli
+
+#### `core/beatport.py` (nuovo)
+
+```python
+from dataclasses import dataclass
+from typing import Optional

+    # implementazione recuperando gli slug + numeric id dalla pagina
+    # https://www.beatport.com/genres — lo script che li estrae va
+    # committato in `scripts/refresh_beatport_genres.py` per potervi
+    # rifare la refresh a mano quando Beatport aggiunge/rimuove generi.

+        """Loop: per ogni track, spotify search → downloader.
+        Emette log/progress sugli stessi eventi degli altri download."""
+        ...
+```
+
+### Riuso codice esistente
+
+- `core/spotify_client.py`: usa `search_track(query) -> Optional[str]` per ottenere lo Spotify URI (o il track object). **Da verificare in fase di implementazione** se il metodo esiste già come funzione pubblica riutilizzabile — se no, estrai la logica di search dal path esistente `download_from_spotify_url` in una funzione pubblica dedicata (refactor mirato, no cambi di comportamento per gli altri consumatori).
+- `core/downloader.py`: usa il path Spotify URI → yt-dlp esistente. `request_stop()` / `reset_stop()` già disponibili.
+- `webui/js/app.js`: riusa il pattern log/progress già in uso per le altre tab.
+- `core/config.py`: aggiunge un solo nuovo campo `beatport_last_genre: str` ai DEFAULTS.
+
+### Frontend
+
+**Nuova tab in `webui/index.html`:**
+
+```html
+<button data-tab="beatport" class="tab-btn">🎧 Beatport</button>
+<section id="tab-beatport" class="tab-panel">
+  <div class="beatport-header">
+    <label>Genere:
+      <select id="beatport-genre"></select>
+    </label>
+    <button id="beatport-load">Carica Top 100</button>
+    <div id="beatport-output-info"></div>
+  </div>
+
+  <div id="beatport-status"></div>
+
+  <table id="beatport-table" hidden>
+    <thead>
+      <tr>
+        <th><input type="checkbox" id="beatport-select-all"></th>
+        <th>#</th><th>Artista</th><th>Titolo</th><th>Durata</th>
+      </tr>
+    </thead>
+    <tbody></tbody>
+  </table>
+
+  <div class="beatport-toolbar" hidden>
+    <span id="beatport-selected-count">0/0 selezionati</span>
+    <button id="beatport-download">⬇ Scarica selezionati</button>
+    <button id="beatport-stop" hidden>■ Interrompi</button>
+  </div>
+
+  <div id="beatport-log" class="log-area"></div>
+</section>
+```
+
+**JavaScript in `webui/js/app.js`:** funzioni `beatportInit()`, `beatportLoadChart()`, `beatportRenderTable(tracks)`, `beatportUpdateSelection()`, `beatportStartDownload()`. Stato locale: `let currentChart = { slug, name, tracks: [] }`.
+
+### Persistenza
+
+- Ultimo genere selezionato → `config.beatport_last_genre`
+- File scaricati → rilevati con `os.path.exists()` sul filename generato dal downloader (stesso pattern degli altri tab)
+- Cache classifica → solo in-memory, si perde a restart (voluto)
+
+### Percorso output
+
+`{output_dir}/Beatport/{Genre Display Name}/`
+
+Es. `/Users/luciano/MUSICA/Beatport/Melodic House & Techno/Kapuchon - Hot Sauce (Extended).mp3`
+
+## Data flow
+
+```
+[JS] User seleziona genere, click "Carica Top 100"
+  ↓
+[JS] api.beatport_fetch_chart("melodic-house-techno")
+  ↓
+[PY] core/beatport.fetch_top100():
+    ├─ Cache hit (< 15 min)? → ritorna cached
+    └─ GET Beatport, estrai __NEXT_DATA__, parse, mappa in BeatportTrack[]
+  ↓
+[JS] Riceve lista, chiama api.beatport_check_existing() per pre-deselezionare i già-scaricati
+  ↓
+[JS] Renderizza tabella
+  ↓
+[JS] User seleziona/deseleziona, click "Scarica selezionati"
+  ↓
+[JS] api.beatport_download_selected(tracks_selected, genre_name)
+  ↓
+[PY] Loop su tracks:
+    ├─ emit log "[i/N] Cerco su Spotify: <artista – titolo>"
+    ├─ spotify_uri = spotify_client.search_track(track.spotify_query)
+    ├─ Se None: emit ✗, continua
+    ├─ emit log "[i/N] Download da YouTube…"
+    ├─ downloader.download_from_spotify_uri(uri, output_dir=<beatport-subdir>)
+    ├─ emit log "[i/N] ✓" o "[i/N] ✗ <motivo>"
+    └─ Se stop_event.is_set(): break
+```
+
+## Matrice errori & recovery
+
+| Errore | Dove | Cosa succede |
+|---|---|---|
+| Beatport 5xx / timeout | fetch_top100 | Retry ×2 con backoff 1s, 3s. Poi solleva `BeatportUnreachableError`. UI: banner rosso "Beatport irraggiungibile. Riprova." con retry |
+| `__NEXT_DATA__` mancante / schema cambiato | fetch_top100 | Dump primi 500 char HTML in `~/Library/Logs/MusicTools/beatport-<ts>.log`, solleva `BeatportParseError`. UI: banner arancione "Impossibile leggere la classifica. Segnala il bug." |
+| Genere non valido | fetch_top100 | `ValueError` early, nessuna richiesta di rete |
+| Spotify search no match | download loop | Log riga singola, marca riga tabella ✗ "non trovato", continua |
+| Spotify creds mancanti | download loop, primo brano | Interrompe subito, banner giallo con link a tab Impostazioni |
+| yt-dlp fallisce | download loop | Log riga singola ✗, continua con il resto |
+| Cartella output non scrivibile | pre-check prima del loop | Errore + banner rosso, non parte |
+| User preme Stop | download loop | `stop_event.set()`, si ferma dopo il brano corrente |
+| Cache stale | fetch_top100 | Shift+click su "Carica" invalida (`force_refresh=True`); comunque expira dopo 15 min |
+
+## Rispetto Beatport / rate limiting
+
+- Un solo GET per classifica (100 brani in un JSON)
+- Cache 15 min → max 4 richieste/ora anche con click ripetuti
+- User-Agent browser, no scraping massivo
+- Zero rischio ban IP in uso normale
+
+## Licenza / piani
+
+La feature è un audio download a tutti gli effetti → il `daily_limit` del piano si applica automaticamente (ogni brano scaricato conta come 1). Il piano `basic` con limite 10/giorno può scaricare al massimo 10 brani dalla Top 100. **Nessuna nuova feature-flag in `server/src/plans.js`.** Il gating avviene già nel downloader esistente.
+
+## Testing
+
+### Unit tests — `tests/test_beatport.py`
+
+Nessuna rete durante i test. Fixture: snapshot HTML reale della pagina Beatport in `tests/fixtures/beatport_melodic_top100.html`.
+
+| Test | Verifica |
+|---|---|
+| `test_parse_next_data_extracts_100_tracks` | Il parser trova esattamente 100 track dall'HTML fixture |
+| `test_track_shape` | Ogni track ha position, title, mix, artists, duration_sec, beatport_id |
+| `test_positions_sequential` | Posizioni 1..100 senza buchi |
+| `test_display_format_matches_txt_files` | `BeatportTrack.display` produce esattamente il formato dei file `.txt` attuali |
+| `test_parse_missing_next_data_raises` | HTML senza `<script id="__NEXT_DATA__">` → `BeatportParseError` |
+| `test_parse_malformed_json_raises` | `__NEXT_DATA__` con JSON rotto → `BeatportParseError` |
+| `test_parse_schema_change_raises` | JSON valido ma senza `results[]` → `BeatportParseError` con contesto |
+| `test_cache_hit_second_call` | 2 chiamate ravvicinate → una sola richiesta HTTP simulata |
+| `test_cache_expires_after_15min` | Freeze time + 16min → nuova richiesta |
+| `test_force_refresh_bypasses_cache` | `force_refresh=True` ignora cache anche fresca |
+| `test_invalid_genre_slug_early_error` | Slug non in `GENRES` → `ValueError` senza toccare la rete |
+
+### Test HTTP mockato
+
+`responses` (o `httpx` mock) per verificare timeout, retry policy, User-Agent inviato.
+
+### Test manuale end-to-end (obbligatorio prima del release)
+
+1. Avvia MusicTools, apri tab Beatport
+2. Seleziona "Melodic House & Techno" → click "Carica Top 100" → tabella si popola in <3s
+3. Deseleziona 90 brani, lascia i primi 10 → click "Scarica selezionati (10)"
+4. Verifica file .mp3 in `{output_dir}/Beatport/Melodic House & Techno/`, metadata Spotify complete
+5. Ricarica lo stesso genere → cache hit (nessuna nuova request osservabile in dev tools)
+6. Cambia genere → nuova fetch
+7. Interrompi a metà download → si ferma pulito dopo il brano corrente
+8. Riavvia app → dropdown ricorda l'ultimo genere
+
+## Rollout
+
+1. Branch `feat/beatport-charts` (opzionale — la feature è additive, zero rischi per il resto)
+2. Bump `core/config.py` VERSION → `v1.8.0`
+3. Note release in `/tmp/notes-v1.8.0.md`:
+   > **Nuova tab Beatport 🎧** — carica le Top 100 per genere direttamente da Beatport e scarica i brani in un click. 30+ generi disponibili.
+4. Commit + tag `v1.8.0` → CI builda macOS + Windows come da flusso standard
+5. Zero cambi lato server (`~/api/`), zero migration DB
+
+## Struttura file impattati
+
+**Nuovi:**
+- `core/beatport.py`
+- `tests/test_beatport.py`
+- `tests/fixtures/beatport_melodic_top100.html`
+
+**Modificati:**
+- `main.py` — 4 nuovi metodi `Api.beatport_*`
+- `core/config.py` — VERSION bump + campo `beatport_last_genre` in DEFAULTS
+- `core/spotify_client.py` — espone `search_track()` come funzione pubblica se non lo è già
+- `webui/index.html` — nuovo tab button + section
+- `webui/js/app.js` — funzioni `beatport*`
+- `webui/css/*.css` — stile tabella e toolbar (riuso classi esistenti dove possibile)
+- `requirements.txt` — nessuna nuova dipendenza runtime (`requests` è già presente per gli altri client HTTP; `__NEXT_DATA__` si estrae con `re.search` + `json.loads`, no BeautifulSoup necessario). Solo dev dep: `responses` per i test HTTP mockati se non già presente
