+## Fase 4: Region System (MeshCore 1.10.0+) (COMPLETATA)
+
+### Implementazione
+Deny-based flood filtering allineato al protocollo MeshCore. Vedi `docs/REGION_SCOPE_DESIGN.md` per i dettagli.
+
+**Fase 4.1: Transport Code in Packet.h**
+- `uint16_t transport_codes[2]` aggiunto a MCPacket
+- `serialize()`/`deserialize()` aggiornati per wire format con transport codes
+- `hasTransportCodes()` helper
+- Costo: +48 B Flash, +16 B RAM
+
+**Fase 4.2: RegionMap Data Structure**
+- `src/mesh/RegionMap.h`: RegionEntry/RegionMap classes
+- SHA256 key derivation, HMAC-SHA256 transport code verification
+- 4 region slots + wildcard entry
+- Costo: +272 B Flash, +168 B RAM
+
+**Fase 4.3: Forwarding Integration**
+- Region filter in `shouldForward()` di main.cpp
+- TRANSPORT_FLOOD: check `regionMap.findMatch()` contro transport codes
+- Legacy FLOOD: check wildcard `REGION_DENY_FLOOD` flag
+- Default: forward everything (nessuna regione configurata = nessun filtro)
+
+**Fase 4.4: CLI Commands + Flash Optimization**
+- `region` — lista wildcard e entry con stato flood (A=allow, D=deny)
+- `region put/remove/allowf/denyf <name>` — gestione regioni (admin only)
+- Per liberare spazio Flash: wrapped `Serial.printf` in mesh/ headers con `#ifndef SILENT`,
+  compresso help text, rimossi alias CLI duplicati (~12 comandi)
+- Costo CLI: +744 B Flash (netto dopo ottimizzazioni: ~1,088 B liberati)
+
+**Alias rimossi (v0.8.0):**
+- `passwd` → usare `password`
+- `erase` → usare `reset`
+- `stats-radio` → usare `radiostats`
+- `stats-packets` → usare `packetstats`
+- `set repeat`/`get repeat` (getter) → usare `repeat`
+- `set advert.interval`/`get advert.interval` (getter) → usare `advert interval`
+- `get radio` → usare `radio`
+- `set tx`/`get tx` (getter) → usare `txpower`
+- `txpower auto on/off` → usare `set tx auto on/off`
+- `set name` (getter) → usare `get name` o `name`
+- `set guest.password` (serial) → usare `password guest`
+
+**Password syntax cambiata:**
+- Serial: `password admin <pw>` / `password guest <pw>`
+- Remote: `password <pw>` / `set guest.password <pw>` (invariato)
