Phase 4: orchestrator + cycles auto-execute

Browse Source 
Componente runtime/ che cabla core+clients+state+safety in un engine
autonomo notify-only: nessuna conferma manuale, ordini combo
piazzati direttamente quando le regole passano. 311 test pass,
copertura totale 94%, runtime/ 90%, mypy strict pulito, ruff clean.

Moduli:
- runtime/alert_manager.py: escalation tree
  LOW/MEDIUM/HIGH/CRITICAL → audit + Telegram + kill switch.
- runtime/dependencies.py: build_runtime() costruisce
  RuntimeContext con tutti i client MCP, repository, audit log,
  kill switch, alert manager.
- runtime/entry_cycle.py: flusso settimanale (snapshot parallelo
  spot/dvol/funding/macro/holdings/equity → validate_entry →
  compute_bias → options_chain → select_strikes →
  liquidity_gate → sizing_engine → combo_builder.build →
  place_combo_order → notify_position_opened).
- runtime/monitor_cycle.py: loop 12h con dvol_history per il
  return_4h, exit_decision.evaluate, close auto-execute.
- runtime/health_check.py: probe parallelo MCP + SQLite +
  environment match; 3 strikes consecutivi → kill switch HIGH.
- runtime/recovery.py: riconciliazione SQLite vs broker
  all'avvio; mismatch → kill switch CRITICAL.
- runtime/scheduler.py: AsyncIOScheduler builder con cron entry
  (lun 14:00), monitor (02/14), health (5min).
- runtime/orchestrator.py: façade boot() + run_entry/monitor/health
  + install_scheduler + run_forever, con env check vs strategy.

CLI:
- start: avvia engine bloccante (asyncio.run + scheduler).
- dry-run --cycle entry|monitor|health: esegue un singolo ciclo
  per debug/test in produzione.
- stop: documenta lo shutdown via SIGTERM al container.

Documentazione:
- docs/06-operational-flow.md riscritto per il modello
  notify-only auto-execute (no conferma manuale, no memory,
  no brain-bridge).

# 06 — Flussi operativi
Tre flussi principali, tutti orchestrati dallo scheduler interno
APScheduler.
I quattro flussi principali del rule engine, tutti orchestrati dallo
scheduler interno APScheduler. Aggiornati al modello di esercizio
**autonomo notify-only** introdotto in Fase 3: Cerbero Bite consulta i
server MCP della suite per leggere il mercato e per inviare l'ordine,
non chiede mai conferma a Adriano e usa Telegram esclusivamente per
notificare quanto fatto.
## Flusso 1 — Avvio engine
```
1. Carica strategy.yaml + strategy.local.yaml (override)
2. Validazione schema (pydantic) — fail veloce
2. Validazione schema + verifica config_hash
3. Acquisisci lock file (data/.lockfile)
4. Apri SQLite, esegui migrations
5. Health check MCP server (versioni + ping)
6. Riconciliatore stato:
a. legge positions con status in {awaiting_fill, open, closing}
b. per ognuna chiama cerbero-memory.is_acknowledged + Deribit get_positions
c. allinea SQLite alla realtà del broker (sempre la realtà vince)
d. log delle discrepanze come WARNING
4. Apri SQLite, esegui migrations, init_system_state
5. Health check MCP (environment_info, ping read tools)
- cerbero-deribit.environment_info → confronta con
strategy.execution.environment; mismatch → kill switch
6. Riconciliatore stato (vedi flusso 6)
7. Health check sistema OK? → arma scheduler
KO? → kill switch + alert + idle
8. Log ENGINE_START
8. Audit log: ENGINE_START
```
L'avvio è progettato per essere **safe**: se qualcosa non torna, il
sistema si rifiuta di operare. Mai partire con uno stato dubbio.

Nessuna conferma manuale: la decisione di apertura è il risultato
deterministico delle regole, non una proposta soggetta ad
approvazione. Il messaggio Telegram è informativo.
### Tempo previsto end-to-end
- Snapshot dati: 3-5 secondi
- Algoritmi puri: < 0.5 secondi
- Conferma utente: variabile (max 60 min)
- Snapshot dati: 3-5 secondi.
- Algoritmi puri: < 0.5 secondi.
- `place_combo_order` su testnet: 1-3 secondi.
Il critical path automatico è **sotto 10 secondi**. La latenza umana
non rallenta i prezzi: se Adriano risponde dopo 30 minuti, l'engine
prima di inviare l'istruzione **rivaluta** spot, mid e dvol e abortisce
l'apertura se le condizioni sono cambiate (slippage > 8% o dvol fuori
banda o macro nuova).

```
### Politica di escalation
Non c'è un ramo "richiesta conferma utente". Ogni `CLOSE_*` viene
eseguito immediatamente; il messaggio Telegram è post-fact e descrive
azione + motivo (formato `notify_position_closed`).
I trigger di uscita non sono uguali. Alcuni hanno **urgenza alta** che
giustifica l'esecuzione anche senza conferma utente entro la finestra:
| Trigger | Urgenza | Comportamento su timeout |
|---|---|---|
| `CLOSE_PROFIT` | Bassa | Attendi prossimo ciclo (può migliorare) |
| `CLOSE_STOP` | **Alta** | Esegui chiusura senza conferma esplicita |
| `CLOSE_VOL` | **Alta** | Esegui chiusura senza conferma |
| `CLOSE_DELTA` | **Alta** | Esegui chiusura senza conferma |
| `CLOSE_TIME` | Media | Attendi 1 ciclo extra; al secondo timeout esegui |
| `CLOSE_AVERSE` | Media | Attendi prossimo ciclo |
Su escalation hard, Telegram riceve un messaggio **post-fact**: "ho
chiuso la posizione X per stop loss perché non ho ricevuto risposta in
30 min e l'urgenza non consentiva attesa".
In caso di fallimento del `place_combo_order` di chiusura (broker
respinge, latenza > soglia, ecc.) la posizione viene rimessa in
`open` e generato un alert `critical`: sarà il prossimo ciclo a
ritentare.
## Flusso 4 — Mensile (Kelly recalibration)
Trigger: cron `0 12 1 * *` (primo di ogni mese alle 12:00 UTC).
```
1. Carica trades chiusi negli ultimi 365 giorni
1. Carica trades chiusi negli ultimi 365 giorni dal repository
2. kelly_recalibration.recalibrate
3. Genera report mensile:
- performance vs simulazione MC
- win rate, avg win/loss, edge
- kelly suggerito vs corrente
- violazioni regole (deve essere 0)
4. telegram.send (informativo, no conferma)
5. brain_bridge.write_note(

content=report
)
6. log KELLY_RECALIBRATED

report, discute con Milito, e committa il nuovo file di config (con
giustificazione nel commit message). Nessun auto-update.
report e committa il nuovo file (con giustificazione nel commit
message). Nessun auto-update del kelly_fraction.
## Flusso 5 — Health check periodico
Trigger: ogni 5 minuti.
```
1. ping ogni MCP usato → ms latency
1. Per ogni MCP utilizzato: probe lightweight
- deribit.environment_info
- macro.get_macro_calendar(days=1)
- sentiment.get_cross_exchange_funding (no asset filter)
- hyperliquid.get_funding_rate("ETH")
- portfolio.get_total_portfolio_value
- telegram: skip (notify-only, no probe non invasivo)
2. SQLite read-write probe (transazione fittizia)
3. lock file ancora valido
4. ultima fill di Cerbero core ricevuta entro tempo atteso
5. state.system_state.kill_switch == 0
Se qualsiasi passo fallisce:
- log HEALTH_DEGRADED
- se 3 fallimenti consecutivi → kill_switch + alert
- se 5 fallimenti consecutivi → restart automatico (1 sola volta al giorno)
3. Lock file ancora valido
4. environment_info.environment == strategy.execution.environment
5. Audit HEALTH_OK / HEALTH_DEGRADED
6. Conta fallimenti consecutivi:
- 3 fallimenti → kill_switch + alert HIGH
- 5 fallimenti → audit + alert CRITICAL (riavvio è demandato a Docker)
```
Il dead-man (`scripts/dead_man.sh`) sorveglia che `HEALTH_OK` venga
scritto: silenzio > 15 min → kill switch via SQLite e alert.
## Flusso 6 — Recovery dopo crash
Quando l'engine riparte:
All'avvio o dopo un riavvio del container:
1. Riapre SQLite + log della giornata.
2. Per ogni posizione `awaiting_fill`:
- Chiede a `cerbero-memory.get_status(instruction_id)`
- Se filled → aggiorna a `open`
- Se cancelled → aggiorna a `cancelled`
- Se ancora pending → mantiene stato e riprende il monitoraggio
3. Per ogni posizione `closing`:
- Stessa logica
4. Per ogni posizione `open`:
- Verifica che esista realmente sul broker (Deribit `get_positions`)
- Se non esiste → flag `state_inconsistent` + alert + kill switch
5. Riconciliazione completata → ENGINE_START.
1. Apre SQLite + log JSONL della giornata.
2. Per ogni `awaiting_fill`/`closing`:
- chiama `deribit.get_positions` per verificare l'esistenza sul broker
- se trovata → aggiorna a `open` (fill confermato)
- se non trovata e l'ordine risulta cancellato → aggiorna a `cancelled`
- se nessuna delle due → flag `state_inconsistent`, kill switch,
alert CRITICAL
3. Per ogni `open`:
- verifica corrispondenza posizione broker vs DB (size, strike,
expiry); discrepanze → kill switch
4. Riconciliazione completata → `audit ENGINE_START`.
Il sistema **mai** prende decisioni di trading durante recovery: solo
allinea lo stato. Il primo decision loop avviene al prossimo trigger
naturale.
