research(alt): sweep 104 strategie alternative su Deribit (153 agenti) + marginal scorer

Ondata di ricerca onesta a largo spettro su BTC/ETH+DVOL certificati: 104 ipotesi distinte (11 famiglie), un agente-finder per ipotesi, verifica avversariale a 3 scettici sui promettenti, sintesi (153 agenti totali). Esito: NIENTE di nuovo regge -> conferma del soffitto strutturale ~1.3 BTC/ETH-direzionale; lo stack TP01+XS01+VRP01 resta imbattuto. - altlib.py: harness condiviso vettoriale leak-free (eval_weights/study_weights, fee-sweep, both-asset + hold-out 2025+). Riproduce i numeri canonici di TP01. - MARGINAL SCORER (study_marginal/marginal_vs_tp01): Sharpe INCREMENTALE vs baseline TP01 (corr, blend uplift OOS, alpha residua) + jackknife OOS (clean-year + drop-best-month). earns_slot = abs!=FAIL & ADDS & robust_oos. Smaschera gli overlay su TSMOM con PASS assoluti fasulli (CMB04, VOL11, ...) e il falso positivo KAMA (ADDS ma muore al jackknife). - runs/*.py (104) script riproducibili per ipotesi; wf_altstrat.js workflow. - Verdetto: 0 candidati deployabili; 2 LEAD fragili (VOL08, STA05_LS) da forward-monitor. - test_marginal_scorer.py blocca baseline + invarianti.

 ### Ricerca post-reset (2026-06-19) — esito
 Prima ondata di ricerca onesta su BTC/ETH certificati (5 track, harness condiviso
 `src/backtest/harness.py`). Sintesi in `docs/diary/2026-06-19-research-synthesis.md`.
 - **TP01 Trend Portfolio — strategia DIFENSIVA robusta (non alpha)** —
  `src/strategies/trend_portfolio.py`. TSMOM multi-orizzonte (1-3-6 mesi) vol-targeted, long-flat,
  50/50 BTC+ETH. Config canonica **PORT LF1d** (**>=12h, 1d raccomandato**, vol-target 20%, leva cap 2x):
  **FULL Sharpe ~1.30, maxDD ~14%; HOLD-OUT 2025-26 Sharpe ~0.31 / +3.5%** mentre il buy&hold 50/50
  faceva −39%/DD60%. Verificata indipendentemente col gauntlet onesto (hold-out + cross-asset +
  plateau + deflated-Sharpe 0.999): **regge**. **Valore = taglio del drawdown ~6× vs buy&hold**, NON
  generazione di ritorno (CAGR ~16% vs ~48% del buy&hold sul toro).
  ⚠️ **LOOK-AHEAD (2026-06-19):** un ffill MIXED-TIMEFRAME su barre open-labeled gonfiava il 4h
  (~1.60 → reale ~1.1). Il calcolo per-singolo-TF è leak-free, ma **NON scendere sotto le 12h**:
  costi+overfitting dominano senza vantaggio (FULL Sh piatto ~1.3 da 12h a 4h; hold-out migliore a 1d).
  Deploy/paper a **1d**. Diari `2026-06-19-tp01-verification.md` / `-tp01-lookahead-fix-lf.md`.
  Paper trader: `scripts/live/paper_trend.py` (1d). Test: `tests/test_trend_portfolio.py`.
  Ri-verifica: `scripts/analysis/{verify_tp01,stress_tp01,tp01_lowfreq}.py`.
 - **XS01 Cross-Sectional Momentum (Hyperliquid) — DIVERSIFICATORE che migliora il portafoglio** —
  `src/portfolio/sleeves.py:_xsec_returns`. Market-neutral su **19 alt liquidi major** Hyperliquid (1d,
  dal 2024): ogni 10g long i 5 più forti / short i 5 più deboli, vol-target 20%. **Scorrelato a TP01
  (~−0.12).** Affinato (2026-06-19): **(a) blend di lookback [30,90]** (z-score cross-sectional mediato,
  come il multi-orizzonte di TP01); **(b) gate di dispersione p30** (entra solo se la dispersione
  cross-section del momentum supera il percentile espandente causale, altrimenti flat — XS è rumore in
  regime compatto). Standalone FULL Sh **1.50** / HOLD 1.71 / DD 11%, plateau robusto (lookback, gate
  p15-35). **Caveat:** storia ~2.5 anni; STAT-MODE (book a 19 gambe non eseguibile a 2k, serve ~20k) →
  monitor forward. NB il gate concentra XS nei regimi dispersi (2025-26 = hold-out alta-dispersione).
  Ricerca `scripts/portfolio/{xsec_research,xsec_blend,xsec_dispgate}.py`. Diari `2026-06-19-hyperliquid-xsec`
  / `-xsec-blend` / `-xsec-dispgate` / `-xsec-universe-expansion` / `-trend-multiasset`.
 - **PORTAFOGLIO ATTIVO = TP01 (55%) + XS01 (25%) + VRP01 (20%)** (`src/portfolio/sleeves.active_sleeves`):
  TP01+XS01 combinato **FULL Sharpe 1.55, HOLD-OUT 1.55, DD 4.4%**. Aggiunto **VRP01** (options
  short-vol, sotto): TP01+VRP01 da solo fa FULL Sh 1.30→1.44 / HOLD 0.31→0.40 a peso 20% (3-way da
  validare locale con dati HL). Report `scripts/portfolio/run_portfolio.py`. Sleeve a date d'inizio
  diverse → outer-join con pesi rinormalizzati (TP01 da solo 2019-20, VRP dal 2021, blend pieno dal 2024).
 - **VRP01 Options Short-Vol — DIVERSIFICATORE da FinanceOld/OptionsAgent** — `src/portfolio/sleeves._vrp_combo_returns`.
  Put credit spread settimanale (vendi put -0.28, compra put -0.10) gated su IV-rank. Idee portate da
  `../FinanceOld/OptionsAgent` (Bear Call Spread + gate d'ingresso). Migliora il lead VRP nudo
  (options_vrp_lab): **(a) defined-risk** taglia la coda (worst-week -16.6%→-7.4%, DD 33%→14%);
  **(b) gate IV-rank>0.30** = vendi vol solo ricca → ribalta HOLD-OUT da -0.25 a +0.28 (l'alpha è il
  filtro di regime). Standalone **FULL Sh 1.10, HOLD 0.60, DD 12%**, positivo/piatto ogni anno (2022
  crash incluso). Scorrelato a TP01 (~+0.01-0.07). **CAVEAT:** premio MODELLATO su DVOL ATM (skew non
  esplicito), book a 1d, f di stress reale non catturato → LEAD robusto, non deploy pieno. Ricerca
  `scripts/research/options_vrp_v2.py` (vs baseline `options_vrp_lab.py`). Test `tests/test_vrp_sleeve.py`.
  Diario `2026-06-20-financeold-analysis-vrp-v2.md`.
 - **Universo Hyperliquid: ESPANDERLO NON aiuta XS01** (provato): 52-asset / top-liquidità dinamico /
  trend-multi-asset → tutti peggiori (small-cap/memecoin diluiscono il momentum relativo; il trend
  multi-asset è ridondante con TP01, corr 0.74). I margini su XS sono nella STRUTTURA DEL SEGNALE
  (blend + gate), non nel numero di asset. I **51** parquet certificati restano per ricerca futura.
  ⚠️ Il test "52-asset = negativo" era in parte inquinato dal backfill sintetico (AXS 83%, ALGO/SAND
  37% di barre vol=0) poi rimosso — vedi correzione estrazione 2026-06-20 sotto; resta comunque vero
  che il long-tail diluisce XS01, ma il numero netto post-fix è 51.
 - **Lead OPZIONI VRP (income short-vol) — quantificato, NON deploy** — `scripts/research/options_vrp_*.py`.
  Vendita put settimanali che incassa il volatility risk premium (IV>RV), scorrelato al trend (~0.07).
  Premio prezzato BS su DVOL reale (`fetch_dvol.py`) + calibrato su quote REALI cerbero-bite mainnet
  (`options_vrp_calibrate.py`): **f reale ≈ 1.0** (non 1.29) → Sharpe ~0.71, DD 33%, coda severa
  (settimane −15..−26% su LUNA/FTX). Diversificatore DEBOLE a premio reale, e short-vol da modello.
  **Regola: niente short-vol da modello in deploy.** Rivalutare quando cerbero-bite cattura un crash
  (per il f di stress reale). Diari `2026-06-19-options-vrp-lab` / `-eval-crypto-backtest-options`.
 - **Edge deboli/scartati:** ML walk-forward BTC (Sh ~0.57), trend 1h L/S (~1.0), RV ETH/BTC (Sh 0.27,
  regime-luck), calendar/seasonality (buy&hold travestito), volume/vol e momentum-reversal (negativi).
 - **MORTO/confermato artefatto:** mean-reversion / fade (negativo anche a fee zero — la vecchia
  libreria +201%/+1238% era contaminazione); trend 5m/15m (fee).
 - **Soffitto strutturale BTC/ETH-direzionale ~1.3** superato SOLO espandendo a un meccanismo diverso:
  cross-sectional su universo Hyperliquid certificato (XS01) → portafoglio Sharpe ~1.55.
 - **Sweep "strategie alternative" (2026-06-20) — 104 ipotesi / 153 agenti / NIENTE di nuovo regge.**
  Ricerca onesta a largo spettro su BTC/ETH+DVOL (harness condiviso vettoriale leak-free
  `scripts/research/alt/altlib.py`, 104 script in `scripts/research/alt/runs/`): 11 famiglie
  (breakout, trend non-TSMOM, mean-rev gated, DVOL/vol, cross-asset pairs, stagionalità, overlay
  rischio, opzioni modellate, microstruttura, ML walk-forward, combo). 16 promettenti, **1 sola**
  sopravvissuta alla verifica avversariale (3 scettici) e comunque NON deployabile. Conferma forte
  del soffitto ~1.3: ogni PASS era hold-out-fitting o **TP01/TSMOM travestito** (trend-beta del
  toro). Unico LEAD: **STA05** (EWMA-cross ensemble, **long-short**) — leak-free, plateau, corr
  hold-out **0.53** a TP01, il blend 0.75·TP01+0.25·STA05 alza l'hold-out 0.31→0.59 (full 1.30→1.24,
  DD 14→16%); MA hold-out corto (536g) → **forward-monitor, non sleeve.** Lezione harness: valutare
  lo Sharpe **MARGINALE vs baseline TP01** (non assoluto) + esigere plateau e jackknife
  drop-one-month sull'hold-out prima di PASS (hanno ucciso 13/14 falsi positivi). Diario
  `2026-06-20-alt-strategies-100agent-sweep.md`.
 - **MARGINAL SCORER (implementato 2026-06-20)** — la lezione "Sharpe marginale, non assoluto" è
  ora codice in `scripts/research/alt/altlib.py`: `study_marginal(name, target_fn)` valuta un
  candidato direzionale BTC/ETH **sia** in assoluto **sia** rispetto al baseline `tp01_baseline_daily()`
  (corr, uplift del blend OOS, beta+alpha residua) e ritorna `earns_slot = (abs!=FAIL) AND
  (marginal==ADDS)`. **Regola: una nuova strategia direzionale si giudica su `earns_slot`, non sullo
  Sharpe assoluto** (gli overlay-su-TSMOM ereditano lo Sharpe di trend e prendono PASS fasulli —
  es. CMB04 PASS assoluto → NEUTRAL marginale). Demo `marginal_demo.py`, test `tests/test_marginal_scorer.py`.
 - **Onestà sul target €50/giorno:** NON raggiungibile su 2000 in 1-2 anni (servono ~130k di
  capitale o un DD da rovina). La leva non è la scorciatoia; la via è target-vol + capitale +
  tempo. La strategia che *guadagna* esiste, ma a ~+€1.5/giorno su 2000.

 # 2026-06-19 — Wave 1 "beat TP01" (26 agenti BTC/ETH): nessun 3º sleeve robusto
 Goal "trova strategie che battano l'esistente e inseriscile": GIA' soddisfatto da XS01 (cross-
 sectional Hyperliquid, integrato → portafoglio TP01 70% + XS01 30%, FULL Sh 1.41 / HOLD 1.15).
 In parallelo, una wave di 26 agenti ha cercato su BTC/ETH miglioramenti del trend + diversificatori.
 ## Esito wave 1 (26 agenti, 25 leak-free): 22 weak, 3 "contender", 1 noise
 I 3 contender, ri-verificati ONESTAMENTE col giudice book-level (`verify_contender.py`) e come
 contributo marginale al portafoglio ATTUALE (TP01+XS01):
 | Candidato | corr TP01 | corr XS01 | +portafoglio (w30%) | Verdetto |
 |---|---|---|---|---|
 | **tsmom_strength_12h** | **+0.49** | — | — | ☠️ scartato: è TP01 più veloce (correlato), non diversifica |
 | **breakout_atr** (trend) | −0.04 | −0.04 | FULL +0.48 / **HOLD +0.05** | ☠️ scartato: gonfia solo il FULL storico (bull), ~zero valore nel hold-out |
 | **highvol_rev** (reversal alta-vol) | −0.08 | −0.05 | FULL +0.20 / **HOLD +0.30** | 🟡 WATCHLIST (vedi sotto) |
 ## highvol_rev: candidato vero ma NON abbastanza robusto → watchlist
 È l'unico genuinamente scorrelato a ENTRAMBI gli sleeve e che migliora FULL+hold-out. MA il mio
 robustezza-check indipendente (plateau, come per XS01) lo boccia per il deploy:
 - **Edge solo a REV_LB=1**: LB2 FULL Sh 0.33, LB3 ~0.05 → **picco a singola-barra, non plateau**.
 - **FULL standalone mediocre** (0.74); la forza è nel hold-out (HOLD 0.97-1.39 vs FULL ~0.7) =
  **HOLD≫FULL = regime-luck dell'alta-vol 2025-26**, non robustezza temporale.
 - È un **reversal** (famiglia morta in tutto il progetto) con concept ribaltato post-hoc
  (low-vol→high-vol). Regge fee fino ~0.3% ma con margine ridotto.
 Stesso difetto (HOLD≫FULL, no-plateau) per cui ho bocciato ieri il RV ETH/BTC regime-luck. La
 disciplina che boccia i falsi positivi vale anche qui → **NON deployato**, in watchlist; rivalutare
 forward (più dati) o se emerge un plateau su un parametro core.
 ## Conclusione
 Wave 1 NON aggiunge un 3º sleeve robusto. **Portafoglio invariato: TP01 (70%) + XS01 (30%).** Le
 famiglie trend (breakout/tsmom-12h) sono ridondanti con TP01 o aiutano solo il bull storico; l'unico
 diversificatore di meccanismo nuovo (highvol_rev) non regge il bar di robustezza. Il vero edge
 incrementale è venuto dall'ESPANSIONE DELL'UNIVERSO (Hyperliquid → cross-sectional), non da altre
 varianti di trend su 2 asset. Direzione futura coerente: più asset certificati + sleeve di
 meccanismo nuovo (non altre trend-variant), col criterio plateau+breadth+contributo.

   2.256–2.265 (Δ 0.04–0.29%). Scarti = rumore intra-barra (snapshot 15-min vs close orario).
   NON e' il feed fantasma testnet (che divergeva >3%).
 2. **`environment_info`** (token cerbero-bite): `environment=mainnet`, `base_url=www.deribit.com`,
   `source=credentials`. **`get_ticker ETH-PERPETUAL`**: `testnet=false`, mark 1703.11.
 3. **Catena, decisivo** — stessa opzione su ccxt.deribit mainnet vs Cerbero MCP:
   `ETH_USDC-26JUN26-1650-P` (put settimanale, delta ~-0.28):
   | fonte | bid | ask | mark_iv | delta | testnet |
   |---|---|---|---|---|---|
   | ccxt mainnet | 25.6 | 26.6 | 54.54% | -0.3150 | — |
   | Cerbero MCP | 25.6 | 26.6 | 54.54% | -0.31513 | False |
   **Identici bit-per-bit.**
 ## Verdetto
 - **Il token MCP di cerbero-bite e' MAINNET; la sua catena opzioni e' reale** (= ccxt.deribit
  mainnet). La contaminazione di PythagorasGoal era il vecchio downloader con token **testnet** su
  `get_historical` (barre OHLCV fantasma), non Cerbero MCP in se'.
 - **Fonte VRP sbloccata**: Cerbero MCP da' bid/ask/IV/greche/OI per-strike (come ccxt) **+** feature
  di regime che ccxt non ha (`dealer_net_gamma`, `gamma_flip_level`, `oi_delta_pct_4h`,
  `liquidation_*`, `funding`, `iv_minus_rv`, `macro`). Utile per validare lo sleeve VRP su piu'
  regimi (raccolta snapshot live + accumulo nel tempo).
 - **Limite residuo**: niente storico profondo della catena -> il backtest pluriennale del VRP resta
  prezzato da modello (DVOL+BS); ma la calibrazione model-vs-reale e' ora robusta e ripetibile
  (snapshot reali su piu' date/regimi).
 ## Collegamento col lavoro VRP (sleeve opzioni)
 Conferma e rafforza `2026-06-19-eval-crypto-backtest-options.md`: lo snapshot ccxt aveva gia'
 mostrato che il backtest SOTTOSTIMA il premio (skew +28% > spread 4% -> bid reale = 1.29x modello).
 Ora abbiamo due fonti mainnet concordi (ccxt + Cerbero MCP) per misurare premio/skew/spread su piu'
 regimi. La cautela centrale resta il **rischio di coda** dello short-vol, non la magnitudine del premio.
 ## Stato cerbero-bite (gia' concluso, contesto)
 Il credit-spread bull-put ETH e' gia' stato giudicato NON robusto su ciclo completo (diario
 `Old/docs/diary/2026-06-09-cerbero-bite-credit-spread.md`: EV breakeven-negativo; "+0.48%/mese" =
 artefatto di finestra calma; coda concentrata col fade ETH). E' una struttura diversa dalla
 put-selling/wheel del progetto `crypto_backtest`.
 > Sicurezza: il token di cerbero-bite e' stato usato solo per la verifica; mai stampato ne' committato

 # 2026-06-19 — Valutazione strategia esterna `crypto_backtest` (trend + opzioni VRP)
 Valutazione critica di un progetto esterno (`/home/adriano/crypto_backtest/`, file chiave
 `STRATEGIA.md`, `production.py`, `options_deribit.py`, `production_equity.csv`) che propone un
 book a 2 motori quasi scorrelati. Rilevante perché tocca proprio la frontiera che la nostra
 ricerca post-reset ha lasciato aperta (le opzioni / volatility risk premium).
 ## Cosa propone
 Portafoglio a due gambe (ρ=0.22 verificato dal CSV):
 - **Sleeve 1 (25%)** — trend spot BTC+ETH a **12h**, long-only se `trend(30g)>0`, vol-target 20%,
  cap 3×, leva globale ~1.07 calibrata a maxDD in-sample −20%.
 - **Sleeve 2 (75%)** — vendita di **put settimanali (CSP/wheel) su BTC** su Deribit, strike a
  **delta 0.28**, hold-to-expiry, IV da DVOL reale, prezzo Black-Scholes.
 Numeri riprodotti dal CSV (finestra 2021-04→2026-06, 272 settimane):
 | Serie | CAGR | Sharpe | maxDD | final |
 |---|---|---|---|---|
 | spot | +12.0% | 0.77 | −18.1% | 1.80x |
 | opt | +15.9% | 1.09 | −20.0% | 2.16x |
 | **blend 25/75** | +15.4% | **1.21** | **−15.2%** | 2.10x |
 | blend ri-levato | +20.5% | 1.21 | −20.0% | 2.63x |
 | B&H BTC | +1.3% | 0.30 | −74.2% | 1.07x |
 corr(spot, opt) = **0.217** confermata. Settimane peggiori opt: 2022-05 (LUNA) −13%,
 2022-06 −11%, 2021-05 −11%, 2022-11 (FTX) −9.7%.
 ## Punto forte — corroborazione indipendente del nostro TP01
 Lo **sleeve spot è quasi identico al nostro TP01** (`src/strategies/trend_portfolio.py`):
 12h, long-only, trend(30g), vol-target 20%, cap 3×. Due ricerche separate, due dataset diversi
 (loro Binance, noi Deribit certificato), **stessa conclusione**: il trend vol-targeted a 12h è
 l'edge reale e robusto. Il nostro Sharpe è più alto (1.32 vs 0.77 su questa finestra / 1.07
 full-history) perché usiamo un **blend multi-orizzonte 1-3-6m** invece del singolo trend a 30g →
 il blend diversifica gli orizzonti e alza lo Sharpe. Conferma forte per entrambi.
 NB: loro confermano anche le NOSTRE lezioni — intraday ≤1h scartato (costi/rumore), un **bug di
 look-ahead sul 4h trovato e corretto** (identico al nostro audit), MR/condor/strangle nudi e
 collar stretti scartati per overfit/tail.
 ## Punto critico — lo sleeve opzioni guida il 75% ma è prezzato dal proprio modello
 È esattamente il muro che avevamo dichiarato non-backtestabile (W18/19/21, ARGO: niente storico
 chain per-strike gratis). Il loro workaround (BS su **DVOL reale** + payoff sul path realizzato)
 fa emergere il VRP perché IV>RV (misurato BTC IV/RV~1.24). Concettualmente sano, ma la
 **magnitudine è ottimistica** — limiti (in parte ammessi dagli autori):
 1. **Nessun bid/ask**: vendono al mid (BS fair), non al bid. Sulle put OTM settimanali lo spread
   è grosso → premio reale nettamente inferiore.
 2. **Skew ignorato**: prezzano put a delta-0.28 (OTM) con DVOL = **IV ATM**. Il mercato carica le
   put molto di più (skew di crash) → modellano la vol sbagliata proprio sull'opzione venduta.
 3. **Coda sotto-modellata**: settimana peggiore solo −13% attraverso LUNA/FTX → sospettosamente
   benigno per un venditore di put nudo. Gap, illiquidità di roll e settlement inverso (coin-settled)
   sono approssimati.
 4. **Leva senza funding** (ottimistico) + **bias di finestra** (parte vicino al top 2021,
   favorevole a un book short-vol DD-capped).
 Il blend Sharpe 1.21 è dominato dallo sleeve income (Sharpe 1.09, peso 75%). Con bid/ask + skew +
 coda realistica lo sleeve income vale plausibilmente molto meno (Sharpe reale stimato ~0.7-0.9),
 e il blend scende di conseguenza.
 ## Verdetto
 - **Lo spot conferma il nostro TP01** → ottima validazione incrociata; nessuna azione necessaria
  se non notare che il nostro blend multi-orizzonte è leggermente migliore.
 - **Lo sleeve opzioni è il lead più promettente per superare il soffitto Sharpe ~1.3**, perché
  aggiunge una fonte di rendimento di natura DIVERSA (volatility risk premium), proprio ciò che i
  nostri 9 track (A-I) non hanno trovato dentro il puro direzionale BTC/ETH. La combinazione
  trend (lungo-vol) + short-vol income è strutturalmente sana e la ρ=0.22 è reale.
 - **MA i suoi numeri vanno dimezzati mentalmente** finché non girano su prezzi reali. Il 75% di
  allocazione a un edge prezzato dal proprio modello è il rischio n.1.
 ## Prossimi passi onesti se si vuole inseguire questo lead
 1. **Quote reali Deribit** (bid/ask), anche solo recenti: misurare il premio reale vs modellato
   sulle put delta-0.28 settimanali, e quanto Sharpe sopravvive allo spread.
 2. **Prezzare allo skew vero** (IV della put OTM, non DVOL ATM).
 3. **Stress su una settimana di crash a prezzi reali/illiquidi** (rollabilità, assignment, gap).
 4. **Paper trading su Deribit testnet** dello sleeve opzioni prima di qualsiasi capitale.
 Coerente con la regola del progetto (lezione v2.0.0): un edge full+OOS robusto su prezzi MODELLATI
 non è un edge finché non è verificato su prezzi reali ed eseguibili.

 ## AGGIORNAMENTO — verifica su QUOTE REALI Deribit (`scripts/research/options_real_quote_check.py`)
 Fatta la verifica concreta (PARTE 1: catena reale Deribit mainnet pubblico; PARTE 2: ri-esecuzione
 dello sleeve CSP con haircut reale sul premio). **Risultato che RIBALTA una mia critica.**
 Snapshot del 2026-06-19, scadenza settimanale 2026-06-26 (~6.2 DTE), put delta −0.277 (strike 61k,
 3.1% OTM), underlying 62.965:
 | Grandezza | Valore |
 |---|---|
 | IV ATM (≈ DVOL) | 37.2% |
 | IV put OTM (mark) | 42.1% (**skew +4.8 pt**) |
 | premio put: BID / mark / ask | 598 / 623 / 630 USD |
 | spread bid/mark | 0.96 (spread ~4%) |
 | premio MODELLATO dal backtest (BS @ IV-ATM) | **463 USD** |
 | **HAIRCUT premio reale(BID)/modello** | **1.29** |
 **Il backtest SOTTOSTIMA il premio, non lo sovrastima.** Prezzando la put OTM con la DVOL (IV ATM)
 ignora lo skew (+28% sul premio lordo); il bid/ask la riporta giu' solo del 4% → vendendo al BID
 reale incassi **1.29×** il premio modellato. Lo sleeve modellato (Sharpe 1.13) e' quindi
 **conservativo sul premio** alle quote attuali; col premio reale salirebbe (Sharpe → 1.83 a f=1.29).
 **Ma la critica vera si SPOSTA, non sparisce:** lo skew esiste perche' il mercato prezza la coda
 grassa: piu' premio = esattamente perche' i crash fanno male. La sensitivity mostra il punto di
 rottura — lo sleeve regge finche' incassi >~85% del premio modellato (Sharpe 0.59 a f=0.85), va a
 zero a f=0.70, negativo a f=0.55. Lo snapshot e' in **regime calmo** (IV ATM 37%, bassa per crypto);
 in un crash lo spread si allarga molto e potresti non riuscire a rollare. Quindi:
 - ✅ **Concern "premio sovrastimato" = SMENTITO** (alle quote attuali e' anzi sottostimato).
 - ⚠️ **Concern "rischio di coda + spread in stress" = CONFERMATO e ora e' IL rischio centrale.**
  Il backtest cattura i crash realizzati 2021-26 (DD −20%) ma non l'intera distribuzione di code
  possibili, e usa spread calmi. La f reale in settimana di crash e' < 1 e lo spread esplode.
 **Verdetto aggiornato:** lo sleeve income e' piu' solido di quanto temessi sul *premio* (il VRP +
 skew e' reale e generoso), ma resta una strategia short-vol il cui rischio vero e' la **coda** e la
 **liquidita' di roll nello stress**, non la magnitudine del premio. Prima del capitale: ripetere lo
 snapshot nel tempo (specie in regimi di IV alta), misurare lo spread in giornate di stress, e
 paper-trade su testnet. Il lead per superare il soffitto Sharpe ~1.3 (aggiungere il VRP a TP01)
 resta valido e ora meglio quantificato.

 # 2026-06-19 — Ricerca frattale multi-agente (63 agenti) su BTC/ETH
 Su richiesta: 50+ agenti in parallelo a cercare strategie NUOVE ispirate ai due documenti
 frattali (`Libro_frattali` + `Pythagoras_Trading_Prediction`), timing/asset diversi, ognuna
 validata sull'harness onesto. Eseguito come Workflow: **63 agenti, ~2h, 3.8M token.**
 ## Cosa è stato testato
 16 concetti frattali estratti dai documenti (sotto la patina esoterica: coscienza, frequenze
 Solfeggio, numeri sacri → idee testabili): alfabeto candle U/D/0 (3-6, LONG), Fourier/cicli,
 ricorrenza di Poincaré (analoghi kNN), centro di inversione Evideon (mirror tempo+prezzo),
 indicatore H-C (~588/25 ≈ 23.5 barre), numeri-universali come periodi, invarianza di forma,
 entropia di Shannon ("coscienza") come gate, confluenza multi-TF, grammatica composizionale,
 fase-ricorrenza. × BTC/ETH × {5m,15m,1h} = **52 ipotesi**.
 Ogni segnale: scritto da un agente come funzione `signal()`, valutato da `eval_signal.py`
 (stesso harness onesto) con **guard automatico anti-look-ahead** (ricalcolo su prefissi).
 Superstiti → verifica avversariale con sblocco una-tantum del **hold-out 2025-26**.
 ## Esito
 - **Verdetti**: 29 rumore, 12 "real" (netto-fee positivo ma non battono il buy&hold), 11 "edge"
  (in-sample: battono B&H + null p<0.05 + leak=0).
 - **Guard anti-look-ahead**: nessun leak passato (gli agenti hanno prodotto segnali causali; i
  pochi tentativi con futuro sono stati auto-squalificati e corretti).
 - **Hold-out (la prova del nove)**: dei **11 superstiti in-sample, 10 REFUTATI** — performance
  catastrofica nel 2025-26 (hurst-DFA −0.49, hc-cycle −0.83, vol-accel −1.16, universal-periods
  −0.42…−1.04, spectral-entropy −0.38/+0.29, multitf −0.49, solfeggio-BTC −0.64). Stessa firma di
  sempre: **regime-luck del toro 2018-2024, sparito out-of-sample.**
 - **1 "confermato"** dalla verifica per-agente: `momentum_solfeggio_cycle` **ETH 1h** (holdout
  Sharpe +1.19, ret +49% mentre il buy&hold ETH faceva −49%). Sembrava un trionfo.
 ## Ma il "vincitore" cade al test cross-asset (kill decisivo)
 Il guard per-agente valuta un asset alla volta e non poteva vedere il quadro. Ho rieseguito **lo
 stesso identico codice** sui due major:
 | Signal (identico) | FULL Sharpe | HOLD-OUT Sharpe | HOLD-OUT ret |
 |---|---|---|---|
 | Solfeggio-cycle su **ETH** 1h | 1.54 | **+1.19** | +49% |
 | Solfeggio-cycle su **BTC** 1h | 1.17 | **−0.25** | −7.5% |
 Un edge robusto non fallisce sull'altro major. La stessa logica (long-only ~20% esposta, filtro
 SMA(588), timing su ciclo ~24) che ha "schivato" il crash ETH 2025 **perde su BTC nello stesso
 hold-out**. È **fortuna di regime di un singolo asset**, non skill. Aggravanti: costanti
 numerologiche ad-hoc (24/588/56, "odore" di overfit, già notato dal verificatore); e con 52 trial,
 trovare 1 segnale che passa un singolo regime di hold-out è atteso per puro caso (1/11 ≈ chance).
 ## VERDETTO
 **La ricerca frattale multi-agente (52 ipotesi, 63 agenti) NON ha trovato alcun edge robusto.**
 I concetti frattali/esoterici si sono comportati esattamente come le famiglie convenzionali (Fasi
 1-3): edge in-sample da regime-luck del toro, refutati dal hold-out; e l'unico che passava il
 hold-out su un asset fallisce sull'altro. **Nessuna magia nei numeri Solfeggio/sacri.**
 Il valore: il processo disciplinato (guard anti-look-ahead + hold-out bloccato + **test cross-asset**)
 ha catturato un falso "trionfo" (+49% vs −49%!) che sul vecchio sistema contaminato sarebbe finito
 dritto in produzione. È la quinta conferma indipendente che su BTC/ETH non c'è un edge facile.
 ## Stato della ricerca dopo tutte le fasi
 Testato: mean-reversion, momentum/trend, vol, lead-lag, hurst, shape-ML, e 16 famiglie frattali ×
 multi-TF/asset. **Niente di robusto, fee-surviving, OOS e cross-asset.** Le direzioni oneste
 restano: (a) accettare il ceiling = long risk-managed (no alpha); (b) allargare l'universo dati
 CERTIFICATO oltre BTC/ETH; (c) fonti di segnale ortogonali al prezzo (on-chain, basis multi-venue,
 opzioni multi-regime) — tutte richiedono nuovi dati certificati. Artefatti: `eval_signal.py`,

 # 2026-06-19 — Espansione universo (Hyperliquid via Cerbero mainnet) → XS01 batte il portafoglio
 L'utente: "ci dovrebbe essere uno storico dati preso da cerbero". Aveva ragione, ed è la chiave per
 superare il soffitto a 2 asset.
 ## La scoperta: Cerbero MCP mainnet serve Hyperliquid (universo ampio e reale)
 Cerbero era la fonte CONTAMINATA (token testnet → reset). MA col token **mainnet** (`.env.mainnet`,
 verificato) il Cerbero MCP serve OHLCV REALI di **Hyperliquid: 230 perp**, storia nativa **dal 2024**
 (pre-2024 = backfill, volume 0; Hyperliquid è nato ~2023-24). Prezzi recenti plausibili.
 ## Certificazione (disciplina del reset: niente fiducia a Cerbero)
 `scripts/analysis/fetch_hyperliquid.py`: scaricati 19 alt liquidi a 1d (2024-2026) e **certificati**
 cross-venue vs Binance + liquidità → tutti PULITI: **flat 0%, mediana 4-9 bps, >1% ≈0%** →
 `data/raw/hl_*_1d.parquet` (namespace dedicato). Caveat onesto: **~2.5 anni** di storia nativa.
 ## XS01 — Cross-Sectional Momentum (la strategia che mancava a 2 asset)
 `scripts/portfolio/xsec_research.py`: market-neutral, ogni 10g long i 5 più forti (ret 30g) / short
 i 5 più deboli, vol-target 20%. Validazione onesta:
 - **Plateau** (non un picco): tante config mom (L30-90, H5-20, k4-6) tutte positive 0.6-0.98.
 - **Fee-robusto**: FULL Sh 0.79→0.68 da fee 0% a 0.3% RT.
 - **Robusto su sottoinsiemi** di asset (metà universo diverse → ancora positivo).
 - **Scorrelato a TP01 (~−0.06)**, **positivo OGNI anno** (2024 +2%, 2025 +19%, 2026 +20%).
 - **Meccanismo sano**: l'edge è nella DISPERSIONE cross-section → debole nel bull compatto 2024
  (quando TP01 è forte), forte nel 2025-26 divergente (quando TP01 è in cash). **Complementare**.
 Diverso dal regime-luck RV ETH/BTC bocciato ieri (2 asset, 2 anni rossi, niente plateau): qui 19
 asset, plateau, fee/subset-robusto, ogni anno positivo, meccanismo noto in letteratura.
 ## Contributo al portafoglio (il criterio del goal: battere l'esistente)
 Confronto EQUO sulla finestra comune (outer-join con pesi rinormalizzati: TP01 da solo 2019-23,
 TP01+XS dal 2024):
 | | TP01 solo | **TP01 70% + XS01 30%** |
 |---|---|---|
 | FULL Sharpe (2019-26) | 1.30 | **1.41** |
 | **HOLD-OUT 2025-26 Sharpe** | 0.31 | **1.15** |
 | HOLD-OUT ret / DD | +3.5% / 7.5% | **+15.1% / 5.2%** |
 | Per-anno | 2022 −2% | **positivo ~ogni anno** |
 → **XS01 BATTE il portafoglio esistente** (risk-adjusted), diversificando in modo robusto. Goal
 soddisfatto: trovata una strategia che batte TP01 e **INSERITA nel portafoglio**.
 ## Integrazione
 - `src/portfolio/portfolio.py`: combine OUTER-join + rinormalizzazione pesi per-giorno (sleeve a date
  d'inizio diverse si attivano quando parte la loro storia; il portafoglio non si tronca). Test nuovo.
 - `src/portfolio/sleeves.py`: `xsec_sleeve` (config mom L30 H10 k5 vol-target 20%); **active_sleeves =
  TP01 70% + XS01 30%**.
 - `fetch_hyperliquid.py`, `xsec_research.py`. 12 test passano.
 ## Caveat onesti (da non dimenticare)
 - **Storia XS solo ~2.5 anni** (2024-2026): robusto entro la finestra (fee/k/subset, ogni anno +),
  ma non ha il record 6-anni di TP01. Cross-sectional momentum è literature-robust → prior favorevole.
 - **STAT-MODE**: book a 19 gambe market-neutral non eseguibile a €2k (rumore arrotondamento) → serve
  ~€20k; per ora è uno sleeve statistico che migliora le metriche, da monitorare forward (paper).
 - L'esposizione reale di XS01 va dimensionata col capitale; a piccolo capitale resta diagnostico.
 ## Stato
 Portafoglio attivo = **TP01 (70%) + XS01 (30%)**, FULL Sh 1.41 / HOLD 1.15. La via per crescere
 ancora: più asset certificati Hyperliquid (l'universo è 230) + più sleeve scorrelati col criterio

 # 2026-06-19 — Options VRP sleeve: infrastruttura + prima validazione onesta
 Impostata la ricerca dello sleeve income opzioni (vendita put settimanali, incassa il volatility
 risk premium IV>RV). Lead identificato dalla valutazione di `crypto_backtest` come la via per
 superare il soffitto Sharpe ~1.3 (fonte di rendimento DIVERSA, scorrelata al trend).
 ## Infrastruttura costruita
 - `scripts/research/fetch_dvol.py`: storia DVOL (IV 30d Deribit) BTC/ETH **2021-03 → 2026-06**
  (1914g) → `data/raw/dvol_*.parquet`. È l'input IV.
 - `scripts/research/options_vrp_lab.py`: motore backtest CSP settimanale. Prezzo put BS su DVOL
  reale + **calibrazione f** (skew/spread vs quote reali), strike a delta target, payoff sul path
  realizzato dei prezzi certificati. Causale (decisione a sell-date, payoff a scadenza). Gauntlet:
  VRP context, sweep f/delta, per-anno, worst-weeks (coda), correlazione + contributo vs TP01.
 - `scripts/research/options_real_quote_check.py` (dal branch): verifica premio su quote reali.
 ## VRP reale (contesto)
 BTC DVOL 61% vs RV 53% → **VRP +7.8 pt, positivo 78% del tempo**; ETH +3.7 pt, 67%. Il premio di
 volatilità esiste ed è più ricco su BTC.
 ## Risultati (book 50/50 BTC+ETH, put settimanali delta -0.28)
 **Tutto dipende dalla CALIBRAZIONE f del premio:**
 | f | Sharpe | CAGR | maxDD | worst-week |
 |---|---|---|---|---|
 | 0.70 | −0.32 | −12% | 51% | −26% |
 | 0.85 | 0.20 | +1% | 35% | −26% |
 | **1.00 (conservativo, IV-ATM)** | **0.71** | +16% | 33% | −26% |
 | 1.15 | 1.22 | +34% | 32% | −25% |
 | **1.29 (reale calm, con skew)** | **1.70** | +52% | 31% | −25% |
 - A f=1.0 (ignora il bonus skew): Sharpe **0.71** — SOTTO TP01. A f=1.29 (skew reale misurato in
  regime calmo): **1.70**. La verità sta in mezzo E f varia col regime (skew più alto nello stress).
 - **Delta**: più ATM = più premio + più rischio (−0.15→Sh 0.25, −0.28→0.71, −0.40→0.95).
 **La CODA è severa (è short-vol):** maxDD standalone **30-33%**, singole settimane **−15..−26%**
 (2021-05 crash, 2022-05/06 LUNA, 2026-02/06). Per-anno (f=1.0): 2022 **−9%**, 2026-YTD **−14%** —
 sanguina negli anni di crash. HOLD-OUT 2025-26: Sharpe **0.04** a f=1.0 (piatto), 0.94 a f=1.29.
 **Diversificazione (reale):** corr settimanale a TP01 **+0.07** (scorrelato). Contributo (f=1.0):
 TP01 70% + OPT 30% → Sharpe settimanale 0.71→**0.97**, DD basso (11%). Anche al premio conservativo
 migliora il portafoglio per pura decorrelazione.
 ## Verdetto — LEAD reale, NON deploy-ready
 - ✅ Il VRP è reale (IV>RV 78%), lo sleeve è **genuinamente scorrelato** al trend (+0.07) e
  **migliora il portafoglio** anche a premio conservativo. È la fonte di rendimento DIVERSA che
  cercavamo per superare il soffitto ~1.3.
 - ⚠️ MA: (a) le metriche headline dipendono da una calibrazione **ottimistica** (f=1.29);
  conservativo (f=1.0) → Sharpe 0.71 con **DD 33%**. (b) Premio **MODELLATO** (BS su DVOL), non un
  backtest su catena reale; la verifica su quote reali è UN solo snapshot calmo. (c) Il **rischio di
  coda** (roll/assignment/gap nello stress, skew che esplode) NON è pienamente catturato.
 - Regola del progetto: **mai deployare uno short-vol prezzato da un modello.** → NON aggiunto al
  portafoglio. Portafoglio attivo invariato: TP01 70% + XS01 30%.
 ## CALIBRAZIONE su quote REALI cerbero-bite (`options_vrp_calibrate.py`) — corregge l'ottimismo
 cerbero-bite GIA' accumula la catena reale mainnet (option_chain_snapshots, BTC 224k / ETH 237k
 righe, 2026-05→oggi). Usandola (non un nuovo snapshotter), misurato il fattore f reale su 223
 snapshot/asset (put weekly ~delta -0.28, vendita al BID):
 - **BTC: f mediano 1.03** (IQR 0.89-1.21), skew reale **+1.9 pt** (IV put 43.5% vs DVOL 41.6%).
 - **ETH: f mediano 0.97** (IQR 0.88-1.11), skew **+1.5 pt**.
 - **Il f reale e' ~1.0, NON 1.29.** Lo snapshot singolo del branch (skew +4.8 → f 1.29) era un
  OUTLIER; sulla media lo skew e' modesto e il bid/ask lo compensa → premio reale ≈ modellato.
 → Il VRP sleeve sta sul punto **f≈1.0 dello sweep = Sharpe ~0.71** (caso CONSERVATIVO), DD 33%,
 hold-out ~piatto (0.04). Non il 1.70 ottimistico. Resta un diversificatore modesto (corr +0.07,
 migliora il portafoglio settimanale 0.71→0.97 a 30%), ma standalone SOTTO TP01 e con coda severa.
 **CAVEAT:** la finestra di calibrazione reale e' ~10 giorni densi (06-09→06-19, cerbero-bite ruota
 le scadenze → i weekly compaiono sparsi) e UN regime calmo. Il f di STRESS resta non misurato.
 ## Verdetto aggiornato
 Al premio REALE (f≈1.0), il VRP sleeve e' un diversificatore DEBOLE (Sharpe ~0.71 < TP01, DD 33%,
 hold-out piatto): la modesta decorrelazione NON giustifica il rischio di coda short-vol senza molto
 piu' dato reale multi-regime. **Confermato NON-deploy.** Il valore vero arriva solo se cerbero-bite,
 continuando ad accumulare, copre un CRASH: lì si misura il f reale di stress e si fa un backtest su
 catena reale. Fino ad allora, lead quantificato ma in attesa. Portafoglio invariato TP01 70%+XS01 30%.
 ## Prossimi passi per graduare il lead a sleeve deployabile
 1. **Accumulo forward di quote reali** (bid/ask + skew della put settimanale delta-0.28, ogni giorno,
   su più regimi) → sostituire il premio modellato con quello reale e misurare f nello stress.
 2. **Stress crash-week con spread reali** (rollabilità, assignment, gap inverso/coin-settled).
 3. **Daily-MTM** dello short put per l'integrazione nel portafoglio giornaliero (ora è settimanale).
 4. **Paper-trade su Deribit testnet** prima di qualsiasi capitale.
 Solo dopo, se regge a premi reali multi-regime, aggiungerlo come 3º sleeve (scorrelato, income).

 # 2026-06-19 — Ricerca v2.0.0: Fase 0 (harness) + Fase 1 (triage superstiti)
 Primo log di ricerca post-reset. Universo certificato: BTC/ETH, 1h. Hold-out 2025+ BLOCCATO.
 ## Fase 0 — harness onesto (`scripts/analysis/research_lab.py`)
 Banco di prova causale per costruzione (modello a SERIE DI POSIZIONE: `pos[i]` decisa entro
 `close[i]`, guadagna `close[i]→close[i+1]`, fee sul turnover |Δpos|). Metriche
 Sharpe/CAGR/DD/exposure/turnover, finestra OOS, **null model a rotazione circolare**
 (p-value: il timing batte il caso?), baseline buy&hold, sweep fee.
 **Self-test del banco (valida l'HARNESS, non una strategia):**
 - buy&hold BTC: Sharpe 0.79 (sanity OK).
 - CHEAT look-ahead (pos = segno del rendimento futuro): Sharpe **58**, p=0.005 → l'engine
  VEDE un edge reale quando esiste.
 - NOISE causale a basso turnover: Sharpe **0.14**, p=0.26 → l'engine NON inventa edge dal
  nulla (niente leak, niente skill spuria).
 Il banco è affidabile. → ogni numero qui sotto è netto fee e causale.
 ## Fase 1 — triage dei 2 superstiti (`scripts/analysis/phase1_survivors.py`)
 Sul feed pulito solo SH01 (shape-ML) e frammenti HONEST mostravano segnale residuo. Delle
 HONEST solo **DIP** è testabile su BTC/ETH (TR01/ROT02 richiedono alt esclusi). Re-implementati
 come serie di posizione, passati ai gate onesti.
 ### DIP reversion (long-only) — ☠️ MORTO
 Griglia 3×3 (n, k) **tutta negativa** su entrambi gli asset (nessun plateau). Config centrale
 n50 k2.0: FULL Sharpe −0.17 (BTC) / −0.06 (ETH); a fee 0% appena +0.02/+0.09 (niente edge nemmeno
 lordo). OOS-VAL marginale (+0.36/+0.16) ma **null p=0.84-0.89** (peggio del caso). Rumore.
 ### SH01 shape-ML (walk-forward LogReg) — ☠️ FEE-DEAD
 Pattern coerente su BTC/ETH, long/short e long-only:
 | Variante | Sh fee0% | Sh fee0.05% | Sh fee0.10% | trade/anno | null p |
 |---|---|---|---|---|---|
 | BTC L/S | +0.32 | −0.70 | −1.71 | 877 | 0.167 |
 | BTC long-only | +0.73 | −0.06 | −0.84 | 555 | 0.072 |
 | ETH L/S | +0.31 | −0.40 | −1.11 | 773 | 0.137 |
 | ETH long-only | +0.46 | −0.04 | −0.53 | 485 | 0.142 |
 C'è un **sussurro di segnale LORDO** (Sharpe 0.3-0.7 a fee zero) ma il turnover (485-877
 trade/anno) lo divora: a fee reale tutte negative, e **nessuna batte il null** (p>0.05). Net-fee:
 rumore.
 ## VERDETTO Fase 1
 **Né DIP né shape-ML sopravvivono su BTC/ETH certificato net-fee.** Nessuno dà Sharpe netto >0,
 nessuno batte il null (p<0.05), nessuno batte il **buy&hold** (Sharpe 0.79/0.84 — di fatto la
 "strategia" più forte vista finora). Si conferma: i "superstiti" della vecchia libreria erano,
 come il resto, non-edge. Chiusi.
 ## Lead onesto per la Fase 2
 L'unico segnale non-nullo è il **gross shape-ML** (Sharpe 0.3-0.7 a fee zero), ucciso dal
 turnover. Direzione: esprimere quel segnale a **turnover molto più basso** (orizzonte di holding
 lungo, soglia forte, o come GATE di regime invece che flip per-barra) per vedere se il sussurro
 lordo sopravvive alle fee. È un lead, NON un edge. Inoltre: la barra reale da battere è il
 **buy&hold** (Sharpe ~0.8) — una strategia di timing deve fare meglio di "stai sempre long",
 net-fee.

 Tutto netto fee 0.10% RT, hold-out 2025+ BLOCCATO. Harness: `research_lab.py`.
 ## Fase 2 — esplorazione famiglie (`phase2_families.py`)
 24 combinazioni famiglia×asset×TF, ognuna: scan griglia → config migliore → gate onesti
 (FULL/OOS-VAL, vs buy&hold, null p-value a rotazione, sweep fee).
 ### Esiti per famiglia
 - **REVERSAL (mean-reversion breve): ☠️ MORTA OVUNQUE.** FULL Sharpe da −1 a −5.6 (peggio a
  15m: fee-death, −5.6 BTC / −4.6 ETH), gross ≈0, null p 0.45-0.82. **Smentisce definitivamente
  la tesi storica del progetto ("l'edge è sempre mean-reversion")**: era artefatto del feed.
 - **TSMOM / MA-cross / Donchian (trend, long-only): segnale REALE ma MODESTO.** Le versioni
  long-only (basso turnover) battono o eguagliano il buy&hold:
  - **MA-cross long-only**: ETH FULL **1.12** / OOS 0.89 / p **0.007**; BTC FULL **0.90** / OOS
    1.99 / p **0.040**. Plateau sulla griglia (ETH 12/48 e 48/192 entrambi 1.1), coerente sui
    DUE asset, basso turnover (53-106 trade/anno). **Unici 2 a passare: battono B&H + OOS>0 + p<0.05.**
  - Donchian long-only: FULL 0.84-0.94, OOS ottimo (BTC 2.37) ma p 0.08-0.10 (pochi trade → null
    rumoroso). TSMOM long-only: ETH 0.83 (≈B&H). Le L/S perdono (turnover + short su asset in trend).
 - **VOL-TARGET overlay**: ≈ buy&hold (FULL 0.77-0.84), p alto → non distinguibile dal B&H, ma è
  un riduttore di vol/DD (mantiene lo Sharpe scalando l'esposizione).
 - **HURST-gate, LEAD-LAG BTC↔ETH**: niente. (Hurst-mom ETH p=0.043 ma sotto il B&H; lead-lag
  fee-dead.)
 ### Verdetto Fase 2
 L'unica cosa reale su BTC/ETH certificato è il **trend-following long-only** (MA-cross in testa):
 un **long con gestione del rischio** che batte il buy&hold di poco (Sharpe ~0.9-1.1 vs 0.8)
 evitando i drawdown peggiori. È un effetto noto in letteratura (time-series momentum), NON alpha
 market-neutral. **Caveat multiple-testing**: 2 flag su ~24 test ≈ soglia del caso; ma la stessa
 famiglia vince su ENTRAMBI gli asset con plateau → è un LEAD genuino, non confermato. La barra
 vera resta il B&H, e l'OOS-VAL alto di BTC (1.99) puzza di "2024 anno di trend forte" → serve la
 prova del hold-out 2025-26 + regimi bear + stress fee/slippage + deflated-Sharpe (Fase 3).
 ## Analisi OPTIONS (`options_analysis.py`)
 Dati reali cerbero-bite mainnet, ma finestra **~2026-05-01→06-11 (~6 sett., REGIME UNICO calmo)**.
 ### Livelli misurati (reali)
 - **VRP (IV − RV) positivo il 100% del tempo**: BTC +10, ETH +14 punti di vol annua. Le opzioni
  sono sistematicamente CARE in questa finestra → vendere vol/covered-call avrebbe incassato premio.
 - **Skew put positivo**: BTC IV put-10%OTM 44% vs call 35% (skew +10 pt); ETH 54 vs 49 (+5). Il
  crash è prezzato (assicurazione cara).
 - **Costo put protettiva** (mensile, %-del-notional): ~10% OTM = **0.98% BTC / 1.36% ETH**; ATM
  3.3%/5.0%; ~15% OTM 0.83%/0.71%. Liquidità: ATM spread ~3%, OTM 7-12%. Mensile ben popolato
  (499-2043 strike), settimanale OTM sottile. Funding perp ≈ 0 (nessun carry).
 ### Verdetto OPTIONS
 **Nessun edge su opzioni è validabile ora**: 6 settimane, regime unico calmo. Il segnale
 VRP-positivo / sell-vol è ESATTAMENTE ciò che brilla in calma e salta in aria nei crash (è il
 rischio che viene pagato) — non testabile senza un crash nel campione. Ruoli legittimi (entrambi
 NON validabili ora, solo forward):
 - **(a) Tail-cap / catastrofe**: put OTM standing su un book long (il candidato trend ha DD grossi).
  Costa ~1-1.5%/mese a 10% OTM — gateabile coi premi reali misurati qui. Overlay per-trade 24h
  INFATTIBILE (strike OTM corti inesistenti/illiquidi); standing settimanale/mensile FATTIBILE.
 - **(b) Harvest del VRP** (covered call / put-spread): +10-14 pt ci sono ORA, ma è una scommessa
  short-vol che richiede un crash nel campione per essere giudicata onestamente. Non l'abbiamo.
 **Raccomandazione**: le opzioni NON sono un'avenue di ricerca a breve (manca storia multi-regime).
 Mosse: (1) lasciare cerbero-bite ad accumulare (gratis, reale, costruisce in avanti il dataset
 multi-regime); (2) rivalutare quando la finestra attraversa un crash/alta-vol; (3) intanto, l'unico
 uso giustificato è come OVERLAY (tail-cap su una strategia spot), gateato sui premi reali qui sopra.
 ## Prossimo passo
 Fase 3 sul solo candidato reale (trend-following long-only, MA-cross): sblocco UNA volta del
 hold-out 2025-26, comportamento nei bear (2018/2022), stress fee×2 + slippage + lag, deflated-Sharpe
 per il multiple-testing. Se regge → è la prima strategia onesta del progetto v2.0.0 (modesta:
 migliora il buy&hold, non lo stravolge). Se non regge → anche il trend era sample-luck.

 Protocollo: selezione config solo pre-hold-out → sblocco una-tantum del hold-out 2025-26 →
 breakdown bear → stress → deflated-Sharpe. Script `phase3_confirm.py`.
 ## Esito: ☠️ NON CONFERMATO — era regime-luck del mercato toro
 ### (1) Pre-hold-out (2018-2024): forte e robusto
 Plateau pieno: BTC Sharpe 0.91-1.16, ETH 1.19-1.48 su tutte le config. **Deflated-Sharpe**
 (N=60 trial): BTC DSR **0.990**, ETH **0.982** → l'effetto trend era REALE e robusto al
 multiple-testing **sul 2018-2024**.
 ### (2) HOLD-OUT 2025-26 (sbloccato una volta) — FALLISCE
 | | buy&hold | trend 24/96 | trend 96/288 (slow) |
 |---|---|---|---|
 | BTC Sharpe | −0.37 | **−0.81** | −0.00 |
 | BTC ret | −32.9% | −33.6% | −5.0% |
 | ETH Sharpe | −0.32 | **−0.95** | −0.01 |
 | ETH ret | −49.3% | −52.0% | −11.3% |
 Il 2025-26 è stato un periodo in DISCESA (buy&hold negativo). Il trend long-only — che "dovrebbe"
 schivare i bear — si è fatto **frullare** (whipsaw): perde quanto o PIÙ del buy&hold, Sharpe negativo
 su ogni config. Solo la MA lentissima (96/288) limita i danni a ~flat (−5/−11%), ma è cherry-pick
 post-hoc e comunque NON positiva.
 ### (3) Per anno — il meccanismo
 Il trend cattura ~70-80% degli anni TORO (2019-2024) e attutisce i bear IN-SAMPLE (2018 −1% vs
 −39%; 2022 −47% vs −65%). MA nel 2025 OUT-OF-SAMPLE ha fatto **peggio** del buy&hold (BTC −25% vs
 −7%; ETH −41% vs −11%): frullato in un mercato choppy/discendente. È il classico fallimento del
 trend-following nei bear laterali. → l'edge 2018-24 era **beta del toro con risk-management**, non
 alpha persistente.
 ### (4) Stress
 FULL regge modestamente (Sharpe 0.65-0.91 anche a fee2x+lag), ma HOLD-OUT è negativo ovunque
 (−0.81 → −1.34) e peggiora sotto stress. Fragile.
 ### (5) Deflated-Sharpe
 DSR>0.95 sul pre-hold-out → conferma che l'effetto era statisticamente reale **nel campione di
 training**. Lezione chiave: **robustezza statistica in-sample ≠ persistenza out-of-sample.** Il
 hold-out bloccato ha colto ciò che DSR da solo non poteva — il cambio di regime.
 ## VERDETTO FINALE (Fasi 0-3)
 **Nessun edge validato, fee-surviving e out-of-sample esiste su BTC/ETH tra le famiglie testate.**
 Il trend-following era il miglior candidato: reale 2018-24 (toro), ma **bocciato sul hold-out
 2025-26** (whipsaw, sotto il buy&hold). La barra realistica resta il **buy&hold** (Sharpe ~0.8
 sullo storico, ma −0.3/−0.4 nel 2025-26: anche "stai long" è stato duro di recente).
 Il processo disciplinato ha funzionato: **ha evitato di deployare un falso edge** (che, sul vecchio
 sistema contaminato, sarebbe finito in produzione). Questo è il valore del reset.
 ## Implicazioni / direzioni
 - **Non deployare** il trend come edge: è regime-dipendente, non batte il buy&hold OOS.
 - Con **solo BTC/ETH prezzo**, il pozzo dei segnali è poco profondo: timing puro non ha edge robusto.
 - Opzioni: nessun ruolo a breve (confermato). Tenere cerbero-bite ad accumulare per uno studio
  multi-regime futuro.
 - Scelte oneste per andare avanti: (a) accettare che il "ceiling" su BTC/ETH è un long risk-managed
  (no alpha) e ottimizzare quello (vol-target per ridurre DD, non per battere il mercato); (b)
  allargare l'universo dati CERTIFICATO (servono asset liquidi+puliti oltre BTC/ETH, che Deribit non
  offre bene → valutare un secondo venue mainnet certificabile); (c) fonti di segnale ortogonali al
  prezzo (on-chain, funding/basis multi-venue, opzioni multi-regime) — tutte richiedono nuovi dati
  certificati prima di poterci credere.

 a `close[i]`, fee 0.10% RT, exit intrabar TP/SL, OOS/per-anno). Branch
 `strategy-research-2026-06`.
 ## I 5 track
 | Track | Famiglia | Esito |

 TSMOM multi-orizzonte (blend 1-3-6 mesi su barre 1h), **vol-targeting** (posizione ∝
 1/vol realizzata, target 20% annuo), portafoglio **50/50 BTC+ETH**, fee 0.10% RT. Un solo
 set di parametri per entrambi gli asset.
 - **LONG-SHORT 50/50:** CAGR +14.2%, **Sharpe 1.00**, maxDD 18.9%, positivo ogni anno 2019-2026.
 - **LONG-FLAT 50/50 (migliore risk-adj):** CAGR +15.9%, **Sharpe 1.32**, **maxDD 13.3%**.
 - Robusto: plateau di Sharpe ~1.0 su griglia target-vol/leva/orizzonti; regge fee fino a 0.40% RT;
  su entrambi gli asset; **non** è un picco fortunato (a differenza delle "star" di Track A).
 - Tesi confermata: il valore del trend è **tagliare il drawdown** (B&H DD ~78% → trend DD ~13-19%)
  con Sharpe ≥ B&H → si può scalare il rischio (target-vol) e diversificare BTC+ETH.
 - Caveat onesto: l'edge è più forte 2018-21 (Sharpe 1.63) che 2022-26 (Sharpe 0.57). Dimensionare
  sul regime recente.
 ## Il verdetto sul target €50/giorno
 Una strategia che **guadagna** in modo robusto ESISTE (Track D). Ma il target "€50/giorno
 medio partendo da 2000 in 1-2 anni" **non è raggiungibile onestamente**: sono ~2.5%/giorno.
 La leva NON è la scorciatoia (alza il DD verso la rovina). La vera leva è **target-vol +
 capitale + tempo**:
 | target-vol | leva usata | CAGR | Sharpe | maxDD | €/giorno (2k) |
 |-----------|-----------|------|--------|-------|---------------|
 | 20% | 0.23x | +14% | 1.00 | 19% | +0.73 |
 | 40% | 0.45x | +28% | 1.00 | 35% | +3.73 |
 | 60% | 0.68x | +40% | 1.00 | 48% | +7.96 |
 | 80% | 0.90x | +50% | 0.99 | 60% | +13.78 |
 Per **€50/giorno steady-state** servono ~**137k di capitale** (config conservativa, DD~19%),
 oppure DD da rovina. Partendo da 2000 a CAGR ~28% (target-vol 40%, DD 35%) il capitale che
 genera €50/giorno arriva in ~10-13 anni, non in 1-2.
 ## Conclusione operativa
 1. **Esiste un edge dispiegabile e onesto**: il trend portfolio vol-targeted (Track D).
   È il primo risultato robusto post-reset.
 2. **Non esiste alcuna scorciatoia** verso €50/giorno su 2000 in 1-2 anni con questi dati
   (BTC/ETH 5m-1h). Il limite è strutturale: due asset, alta correlazione, fee.
 3. Prossimi passi onesti se si vuole alzare il soffitto: (a) dimensionare Track D a un
   target-vol/DD tollerabile e farlo girare in paper, (b) cercare edge di **magnitudine
   diversa** (non più diversificazione di edge deboli) — il che richiede dati che oggi non
   abbiamo certificati (universo più ampio, microstruttura, funding/opzioni backtestabili).

 # 2026-06-19 — Caccia al secondo sleeve: nessun diversificatore robusto (TP01-only resta)
 Continuazione naturale del portafoglio: cercare un secondo sleeve SCORRELATO a TP01 (trend
 long-flat, in cash gran parte del tempo). Criterio: non il Sharpe standalone ma il CONTRIBUTO al
 portafoglio + robustezza. Tool: `scripts/portfolio/second_sleeve_hunt.py` (riusa le RV di trackE).
 ## Candidati testati (relative-value market-neutral ETH/BTC)
 | Candidato | corr TP01 | FULL Sh | HOLD Sh | esito |
 |---|---|---|---|---|
 | RV ratio mean-rev 7d/14d | −0.09/−0.05 | −1.36/−1.03 | −0.62/−0.76 | ☠️ morto (mean-rev dead, come sempre) |
 | RV ratio_trend / xs_momentum 30d | +0.04 | **0.56** | **1.92** | ⚠️ sembrava promosso |
 ratio_trend e xs_momentum danno risultati IDENTICI: su 2 asset "long il più forte / short il
 debole" ≡ "trend del ratio ETH/BTC". È UN segnale (relative-momentum), non due.
 ## Il candidato "promosso" è regime-luck (per-anno + plateau lo smascherano)
 Aggiunto a TP01 sembrava un trionfo: hold-out portafoglio 0.31 → 1.18 (w20%) / 1.51 (w30%),
 corr +0.04. MA:
 - **Hold-out (1.92) >> FULL (0.56)**: bandiera rossa (immagine speculare della trappola di Fase 3).
 - **Per-anno NON robusto**: 2019 +22%, 2020 +7%, 2021 +21%, 2022 +13%, **2023 −17%, 2024 −19%**,
  **2025 +62%**, 2026 +6%. Due anni consecutivi negativi; il "guadagno" è concentrato nel 2025
  (ETH sottoperforma BTC in modo netto e sostenuto). FULL Sharpe mediocre 0.56, DD 41%.
 - **Nessun plateau**: l'hold-out Sharpe oscilla 0.25→1.92 al variare di (N, hold) → picco
  config+regime, non altopiano.
 - Il beneficio FULL al portafoglio è solo **+0.09 Sharpe** (la legittima diversificazione di uno
  sleeve scorrelato a Sharpe 0.56: √(1.30²+0.56²)≈1.42). Il resto del "miglioramento" è il 2025.
 ## Decisione: NON promosso — TP01-only resta il portafoglio deployato
 La stessa disciplina che ha bocciato i falsi positivi in-sample (Fasi 1-3) e cross-asset (frattali)
 deve bocciare questo falso positivo nel hold-out. Il relative-momentum BTC/ETH è un edge debole e
 regime-dipendente (2 anni a −17/−19%), il cui contributo robusto al portafoglio è marginale
 (+0.09 FULL); il grosso del beneficio è la fortuna del 2025. Aggiungerlo significherebbe
 scommettere sul ripetersi di quel regime.
 **Lezione/criterio aggiornato per i futuri sleeve:** "migliora il hold-out" da solo NON basta (il
 hold-out è UN regime). Un secondo sleeve va promosso solo se: causale, corr bassa, **positivo nella
 maggioranza degli anni** (no 2 anni consecutivi rossi), **plateau** sui parametri, e migliora il
 portafoglio su FULL E hold-out — non solo per via di un singolo anno fortunato.
 ## Stato
 Portafoglio = **TP01-only** (difensivo, Sharpe FULL 1.30 / hold-out 0.31). `active_sleeves()`
 invariato. `second_sleeve_hunt.py` resta come tool per valutare candidati futuri col criterio
 corretto (contributo + breadth per-anno + plateau). Il relative-momentum BTC/ETH è in WATCHLIST,

 # 2026-06-19 — Portafoglio di strategie estensibile (TP01 primo sleeve)
 Creato un contenitore di portafoglio (`src/portfolio/`) con TP01 come unico sleeve attivo per ora,
 progettato per aggiungerne altri (ognuno validato col gauntlet onesto).
 ## Design
 - **Sleeve** = una strategia validata che produce una serie di rendimenti netti per-barra
  (datetime-indexed, CAUSALE, netto fee). Opzionale `pos_fn` per le posizioni correnti (live).
 - **StrategyPortfolio**: porta ogni sleeve su griglia GIORNALIERA comune (compounding intra-giorno
  → mixa TF diversi in modo coerente), combina per PESO rinormalizzato sui giorni comuni
  (= equal-capital-by-weight ribilanciato di continuo). Metriche FULL + HOLD-OUT 2025-26 (bloccato)
  + per-anno + standalone per-sleeve, vs benchmark buy&hold 50/50.
 - **Estensibilità**: aggiungere uno sleeve = una riga in `src/portfolio/sleeves.active_sleeves`
  (dopo validazione: research_lab + hold-out + cross-asset + causality guard). Niente sleeve non validati.
 ## Stato attuale (1 sleeve = TP01, peso 100%)
 `scripts/portfolio/run_portfolio.py`:
 - **FULL** Sharpe 1.30 / ret +201% / DD 14.3% / ~€1.52/g su 2k (n=2655 giorni 2019-2026)
 - **HOLD-OUT 2025-26** Sharpe 0.31 / +3.5% / DD 7.5%  (buy&hold 50/50: Sharpe −0.32 / −39% / DD 59%)
 - Per-anno positivo quasi ovunque (2022 −2.1%, 2026-YTD −0.7%)
 - Posizione corrente: **flat** (TP01 in cash nel regime attuale = difensivo)
 ## File
 - `src/portfolio/{__init__,portfolio,sleeves}.py`, `scripts/portfolio/run_portfolio.py`,
  `tests/test_portfolio.py` (6 test, passano). CLAUDE.md aggiornato.
 ## Prossimo
 Il portafoglio è pronto per ospitare nuovi sleeve. Candidati naturali (da validare prima):
 un secondo edge scorrelato a TP01 (TP01 è trend long-flat → serve qualcosa di diverso, es. una
 strategia che lavori quando TP01 è flat). Finché non c'è un secondo edge che regge il gauntlet,

 Ricalcolo TP01 PULITO **per singolo TF** (barre discrete, posizione shiftata +1, NESSUN
 ffill/combine mixed-TF), con un **guard di causalità esplicito** (ricalcolo `target_series` su
 prefisso → `tgt[i]` invariato). Esito (fee 0.10% RT, hold-out 2025-26 bloccato):
 | TF | leak | FULL Sh | FULL ret | HOLD Sh | HOLD ret | HOLD DD |
 |---|---|---|---|---|---|---|
 | 4h | **0** | 1.36 | +204% | 0.27 | +2.8% | 8.3% |
 | 6h | **0** | 1.42 | +217% | 0.21 | +2.1% | 7.9% |
 | 12h | **0** | 1.32 | +198% | 0.22 | +2.3% | 8.6% |
 | **1d** | **0** | 1.30 | +201% | **0.31** | **+3.5%** | 7.5% |
 | buy&hold 50/50 1d | — | 0.92 | +1671% | **−0.32** | **−39%** | 59% |
 ## Lettura
 - **Il path single-TF che ho usato in verify/stress è LEAK-FREE** (guard=0 su ogni TF): il
  gonfiaggio 1.60 stava nel path **mixed-TF ffill** (ensemble/combine, es. trackE), NON nel
  portafoglio single-TF. Per questo il mio 4h era 1.36 (non 1.60).
 - **La conclusione "≥12h" è comunque CORRETTA e la adotto**: il FULL Sharpe è PIATTO ~1.3 da 12h
  a 4h → scendere sotto le 12h NON dà vantaggio reale, aggiunge solo costi/turnover e rischio
  overfit/look-ahead (lo stress mostrava il margine hold-out del 4h fragile a lag/fee). **1d è il
  migliore**: hold-out Sharpe 0.31 (il più alto), DD 7.5%, turnover/costi minimi, leak-free.
 - Allinea anche col numero dell'agente: il "reale ~1.1" è del path mixed-TF corretto; il mio
  single-TF pulito dà ~1.3 FULL. In ogni caso **edge difensivo modesto**, non alpha.
 ## Decisioni applicate
 - **Canonica deploy → PORT LF1d** (era LF4h). `trend_portfolio.py`: docstring aggiornata + nota
  look-ahead; aggiunti `resample_tf`/`resample_1d`, `resample_4h` marcato deprecato per il deploy.
 - **Paper trader → 1d** (`paper_trend.py`: `resample_1d`, `build_bars`, etichette 1d; gira, 5 test ok).
 - **CLAUDE.md**: TP01 ridescritta come DIFENSIVA, canonica ≥12h/1d, gotcha look-ahead documentato.
 - **Gotcha riusabile:** mai ffill/combine MIXED-TIMEFRAME su timestamp open-labeled (`label="left"`):
  la close del bar (nota solo a fine bar) verrebbe propagata indietro all'open-label → look-ahead.
  Il calcolo per-singolo-TF a barre discrete (posizione +1) è sicuro; il guard prefix-recompute lo prova.
 ## Verdetto invariato
 TP01 resta la prima strategia onesta del progetto: **difensiva** (taglia il DD ~6× vs buy&hold,
 hold-out 2025-26 positivo su entrambi gli asset), modesta nel ritorno. Deploy a **1d**, forward-only
 paper trader, prima di qualsiasi capitale reale.

 # 2026-06-19 — Verifica TP01 (branch strategy-research-2026-06) col gauntlet onesto
 Una ricerca PARALLELA (branch `strategy-research-2026-06`, AdrianoDev) dallo stesso baseline
 v2.0.0 ha trovato TP01 come "unica vincitrice". La mia linea (Fasi 2-3) aveva bocciato il trend
 sul hold-out 2025-26. Ho riprodotto TP01 VERBATIM (`scripts/analysis/verify_tp01.py`) e l'ho
 passato al mio gauntlet. **TP01 REGGE — la mia conclusione precedente era incompleta.**
 ## TP01 = TSMOM 30/90/180g, **vol-target 20%**, leva cap 2x, **long-flat**, portafoglio 50/50 BTC+ETH (4h)
 ## Esiti del gauntlet
 **(A) Multi-TF (4h cherry-picked?) — NO, plateau robusto:**
 | TF | FULL Sharpe | HOLD-OUT Sharpe |
 |---|---|---|
 | 15m | 0.93 | −0.31 |
 | 1h | 1.32 | +0.20 |
 | **4h** | **1.36** | **+0.27** |
 | 1d | 1.30 | +0.31 |
 1h/4h/1d danno tutti FULL ~1.3 e hold-out positivo → non è un artefatto di un singolo TF (solo il 15m, fee-sensibile, fallisce).
 **(C) HOLD-OUT 2025-26 (il test che ha ucciso il mio trend 1h) — TP01 PROTEGGE:**
 | | Sharpe | ret | DD |
 |---|---|---|---|
 | **TP01 portfolio** | **+0.27** | **+2.8%** | **8.3%** |
 | buy&hold 50/50 | −0.35 | **−39.4%** | 59.8% |
 **(D) Cross-asset nel hold-out — regge su ENTRAMBI** (BTC sleeve +2.9% Sh 0.24, ETH +2.4% Sh 0.24).
 A differenza del "vincitore" frattale (+ETH/−BTC), TP01 protegge coerentemente su BTC E ETH.
 **(B) Per anno:** positiva quasi ogni anno 2019-2026 (eccezioni piccole: 2022 −2.4%, 2026-YTD −0.9%),
 DD annui 1-12%. Il claim "positiva ogni anno" è lievemente ottimistico ma sostanzialmente vero.
 ## Perché TP01 regge dove il MIO trend (Fase 3) è caduto
 La differenza chiave è il **VOL-TARGETING** (che NON avevo combinato col trend): TP01 scala
 l'esposizione ∝ 1/vol_realizzata → nel crollo 2025-26 la vol è esplosa e TP01 si è messo
 quasi in cash, schivando il drawdown. Il mio MA-cross 1h aveva esposizione fissa ed è rimasto
 long nel chop → frullato. Concorrono: TSMOM multi-orizzonte (più liscio del MA-cross), long-flat
 (niente perdite short), diversificazione 50/50. **La mia "trend = regime-luck" era vera per il
 trend NUDO; TP01 = trend + vol-target + portafoglio è un'altra cosa, e robusta.**
 ## Cosa È onestamente TP01 (no oversell)
 - **Edge DIFENSIVO, non alpha**: FULL Sharpe 1.36 vs buy&hold 0.92 — MA CAGR +16.6% vs +48.1%.
  Su tutto il toro il buy&hold ha reso ~8x di più. Il valore di TP01 è il **DD** (13.8% vs 77.5%
  full; 8% vs 60% nel hold-out) e la **protezione dai crash**.
 - Nel hold-out 2025-26 ha fatto solo +2.8% (Sharpe 0.27, basso): ha **protetto, non profittato**.
 - Un solo regime di hold-out, ma il vol-targeting è meccanico (high vol → low expo) → generalizza
  per costruzione meglio di un timing fittato.
 - Config canonica (30/90/180, vol20%, lev2x) non iper-tunata; 4h non cherry-picked (plateau).
 ## VERDETTO
 **TP01 è la PRIMA strategia onesta e robusta del progetto post-reset.** Supera il mio gauntlet
 (hold-out positivo su entrambi gli asset, plateau multi-TF, causale, fee-aware). È modesta e
 difensiva (Sharpe ~1.3, soffitto strutturale dichiarato corretto), ma è reale: migliora il
 rischio/rendimento del buy&hold tagliando i drawdown e proteggendo nei crash. La ricerca parallela
 ha fatto centro proprio sul pezzo che la mia linea non aveva combinato (vol-target sul trend).
 **Raccomandazione:** integrare il branch su main (modulo `trend_portfolio.py` + paper trader),
 trattare TP01 come baseline operativa difensiva. Aspettative oneste verso il target €50/g: a
 Sharpe 1.3 / CAGR 16.6% servono molto capitale o leva (con più DD) — TP01 è un fondamento solido,
 non una scorciatoia.
 ## STRESS-TEST (`scripts/analysis/stress_tp01.py`, integrato e rieseguito sul modulo vero)
 | Dimensione | Esito |
 |---|---|
 | **Sweep fee** | FULL robusto fino a **0.40% RT** (Sh 1.44→1.36→1.28→1.13). HOLD-OUT SOTTILE: +2.8%/Sh0.27 a 0.10% → ~flat (Sh 0.03) a 0.40% |
 | **Lag/slippage** | FULL robusto (1.29-1.43). HOLD-OUT si erode: lag1(4h)→Sh0.12, lag2→−0.02, lag1+fee0.20%→0.04 |
 | **Plateau parametri** | OTTIMO — target_vol/leva/orizzonti/vol_win tutti reggono o migliorano (orizzonti 20/60/120 → Sh 1.61). **NON un picco cherry-picked** |
 | **Deflated-Sharpe** | DSR **0.999** a N=10/40/100 trial → il Sharpe FULL non è artefatto di multiple-testing |
 **Verdetto stress (onesto):**
 - **Robustezza FULL-period: FORTE.** TP01 supera fee 0.40%, lag, ampio plateau di parametri, e
  deflated-Sharpe. NON è overfit né cherry-picked — la proprietà robusta è il **taglio del
  drawdown** (13.8% vs 77.5% full; 8% vs 60% hold-out), invariante a tutto lo stress.
 - **Edge di RITORNO nel hold-out: REALE ma SOTTILE e sensibile alla frizione.** Nel 2025-26 ha
  schivato il crash in modo affidabile (DD 8% vs 60%) ma ha **protetto più che profittato** (+2.8%,
  Sh 0.27), e quel sottile positivo si assottiglia a zero sotto fee2x o lag 2 barre.
 **Conclusione:** la proprietà **deployabile e robusta di TP01 è la PROTEZIONE del drawdown**, non
 la generazione di alpha. È una strategia difensiva genuina (prima del progetto a superare gauntlet
 + stress), ma a basso ritorno: il valore è "Sharpe ~1.3 con DD ~6× più piccolo del buy&hold",
 non "battere il mercato". Per il capitale reale: il vol-targeting + long-flat sono meccanici e
 generalizzano; il rischio residuo è la frizione di esecuzione sul filo del sottile edge di ritorno
 nei regimi avversi → da monitorare col paper trader forward-only prima di scalare.

 # 2026-06-19 — Track A: Trend / Momentum su BTC & ETH (dati certificati)
 Prima ricerca di strategie NUOVE post-reset (track A = trend/momentum). Tool:
 `scripts/research/trackA_trend.py` (harness onesto `src/backtest/harness.py`, fee 0.10% RT,
 IS/OOS 65/35, griglia su entrambi gli asset, fee sweep, stress leva). Run:
 `uv run python scripts/research/trackA_trend.py`.
 ## Cosa è stato testato
 - **TSMOM** (segno del ritorno N-barre, hold H) long/short e long-only.
 - **EMA crossover** (fast/slow) come filtro di trend.
 - **Donchian breakout** (entry ONESTO: breakout rilevato con `close[i]`, fill a `close[i]`).
 - **Vol-scaled / regime-gated TSMOM** (momentum preso solo se |z| > gate, z = ritorno/vol).
 - Griglia ampia su **BTC e ETH**, **1h / 15m / 5m**. 480 celle OOS totali.
 Tutto entry-eseguibile: direzione e prezzo decisi con dati ≤ `close[i]`, fill a `close[i]`.
 Nessun uso di `returns[i]` (che codifica `close[i+1]`). Hold approssimato come catena di
 posizioni non sovrapposte di H barre (la fee si ammortizza su H barre — costo onesto).
 ## Risultati — la fotografia onesta
 **Celle positive OOS per timeframe:**
 | TF | celle positive / totali |
 |----|----|
 | **1h**  | 39 / 160 |
 | **15m** | **0 / 160** |
 | **5m**  | **0 / 160** |
 → **Trend intraday (5m/15m) è MORTO**: lo drag della fee (più trade = più 0.10% RT) annienta
 qualsiasi segnale. Drawdown 80-99%, Sharpe da −0.6 a −2.2. Niente da salvare.
 **Su 1h** c'è qualche cella positiva, ma il contesto la ridimensiona:
 - La finestra **OOS è un singolo regime**: il taglio 65% cade a **set/dic 2023**, quindi
  l'OOS è ~2023→2026 (in gran parte toro 2024). Tutto il 2018-2022 (orso 2018, crash 2020,
  toro 2021, orso 2022) è IN-SAMPLE. "Positivo OOS" qui ≈ "il trend ha fatto soldi nel toro 2024".
 - **Benchmark buy & hold sulla stessa finestra OOS**: BTC **+134%**, ETH **−21%**.
  - Tutte le `TSMOM_LONG` e metà delle celle BTC fanno **MENO** del B&H → è **beta**, non edge.
  - Le poche che battono il B&H lo fanno **solo su ETH** (dove il B&H era negativo): catturano
    anche i ribassi. Quello è timing reale — ma vedi sotto.
 **Le "star":** VOLSCALED_TSMOM BTC 1h (N=20,H=48,vw=100,z=0.5) = +367% OOS, Sh 0.91, DD 32%,
 €/d(2k) +2.56; ETH 1h (N=20,H=48,vw=50,z=1.0) = +197% OOS, Sh 0.60. **MA sono celle fortunate:**
 i vicini di griglia crollano (stesso N/H, vw=50 invece di 100 → +21% invece di +367%; z=1.0 → +34%).
 Non è un altopiano robusto, è un picco isolato. E il P&L è concentrato nel 2024 (+110% su BTC),
 con 2025/2026 deboli o negativi per molte celle.
 **Consistenza cross-asset (un edge vero regge su ENTRAMBI):** su 480 celle, solo **2** sono
 positive OOS su BTC *e* ETH:
 - `TSMOM_LONG 1h N=200 H=48` → ma è long-only ≈ beta (fa meno del B&H su BTC).
 - `DONCHIAN 1h N=200 H=12` → l'unico candidato "vero" simmetrico, ma **marginale**:
  OOS BTC +9% / ETH +15%, **Sharpe 0.15-0.19**, troppo debole per dispiegarlo.
 **Fee sweep / leva:** le star reggono lo sweep 0.0005-0.002 (è 1h, poche operazioni), e lo Sharpe
 è invariante alla leva (come deve) — ma la leva 3x porta i DD a 75-91% e affonda le celle marginali.
 ## Verdetto
 **Nessun edge trend/momentum dispiegabile, onestamente, su BTC/ETH oggi.**
 - 5m/15m: morti per fee. Chiuso.
 - 1h: esiste un **residuo di segnale trend** (le celle che battono il B&H negativo di ETH non sono
  solo beta), ma è (a) testato su **un solo regime OOS** (toro 2023-2026), (b) **non robusto** di
  griglia (picchi isolati), (c) sull'unica cella simmetrica robusta-su-entrambi (Donchian N=200)
  **troppo debole** (Sharpe ~0.17). Sharpe netti ~0.3-0.9 nel caso migliore = sotto la soglia per
  rischiare capitale reale.
 Conferma la lezione del reset (il superstite storico era trend-following, non mean-reversion): il
 trend è la direzione *meno sbagliata*, ma sui dati certi non basta a fare un edge. Coerente con
 Track C (mean-reversion = artefatto).
 ## Prossimi passi possibili (non ancora edge)
 - Walk-forward multi-regime (non un singolo taglio 65/35) per stressare Donchian-1h-N200 su orso 2018/2022.
 - Trend 1h **con filtro di volatilità/regime più ricco** o portafoglio BTC+ETH per diversificare il
  rischio di regime — ma solo se emerge robustezza di griglia, non altri picchi fortunati.
 - Restare scettici: finché un trend non è positivo su griglia + su entrambi gli asset + su ≥2 regimi
  OOS, **non si dispiega**.

 # 2026-06-19 — Track B: ML / feature-prediction su BTC & ETH (walk-forward onesto)
 Esperimento di ricerca sulla direzione **machine-learning** post-reset, su dati Deribit
 mainnet certificati (solo BTC/ETH). Tool: `scripts/research/trackB_ml.py` (runnable
 `uv run python scripts/research/trackB_ml.py`). Tutto netto fee, strict walk-forward,
 held-out tail mai usato per scegliere i config.
 ## Metodologia (anti look-ahead — la lezione della v2.0.0)
 - **Feature** (21): ritorni multi-lag (1/2/3/6/12/24), geometria candela (body/upper/lower
  shadow su range, range normalizzato, body lag-1), momentum48 + accelerazione, RSI14,
  estensione ATR-normalizzata vs EMA24, vol realizzata 24/72 + ratio, posizione del close
  nel range 24/72, z-score del volume. **Tutte backward** (note solo a `close[i]`).
 - **Label**: segno del ritorno forward su H barre, `sign(close[i+H]/close[i])`.
 - **Strict walk-forward**: per predire il blocco che inizia a `b`, si addestra
  scaler+modello SOLO su indici `< b-H` (gap di H → label completamente realizzata nel
  passato), finestra rolling delle ultime W barre. Retrain ogni K=250 barre. Mai fit sul
  futuro. **Nessun leakage** (verificato: la label più recente del train usa `close[b-1]`).
 - **Esecuzione**: entry a `close[i]` nella direzione predetta, hold fino a H barre
  (no TP/SL); il no-overlap dell'harness distanzia i trade ≥ H barre.
 - **Modello**: `LogisticRegression(class_weight='balanced')`. Soglia di probabilità per
  filtrare i segnali deboli (long se p>0.5+thr, short se p<0.5-thr, altrimenti flat).
 - **Selezione su DEV** (primo 75%), **conferma una volta sola** sull'held-out tail (ultimo 25%).
 - Griglia: W∈{4000,8000,16000}, H∈{6,12,24,48}, thr∈{0,0.03,0.06,0.10}, BTC & ETH, 1h.
  Fee-sweep 0.05/0.10/0.15/0.20% RT. Turnover/time-in-market sempre riportati.
 ## Risultato — esiste un segnale, ma è debole e a basso turnover
 **Pattern netto e robusto della griglia**: la positività compare SOLO nelle celle a basso
 turnover → **W grande (16000) + H lungo (24) + soglia alta (0.10)**. Tutto ciò che gira
 veloce (thr basso, H corto, e soprattutto il **15m**) **muore sulle fee**.
 - **15m**: 0/12 celle positive in dev (la migliore −47%, le altre −99%). Stesso win-rate
  52–56% del 1h, ma il turnover lo polverizza. Conferma di prim'ordine: l'edge per-trade è
  minuscolo, sopravvive solo se si tradano poche barre.
 - **1h, dev**: 19/96 celle net-positive con Sharpe>0. Famiglie threshold-robuste:
  `BTC W16000 H12`, `BTC W8000 H12`, `BTC W16000 H24`, più ETH W16000 H12/H48 marginali.
 ### Held-out tail (2024→2026, mai toccato in sviluppo)
 | config | trades | wr% | net% | Sharpe | DD% | mkt% | €/g(2k) | long% | B&H tail |
 |---|---|---|---|---|---|---|---|---|---|
 | **BTC W16000 H24 thr0.10** | 333 | 52.9 | **+83.7** | 0.57 | 23 | 12 | **+0.58** | 44 | +3.9% |
 | BTC W16000 H12 thr0.10 | 382 | 53.4 | +37.6 | 0.35 | 25 | 7 | +0.26 | 54 | +3.9% |
 | ETH W16000 H12 thr0.10 | 364 | 57.7 | +23.7 | 0.24 | 35 | 7 | +0.18 | 68 | −38.4% |
 | ETH W16000 H48 thr0.06 | 215 | 55.3 | −13.3 | 0.08 | 64 | 16 | −0.10 | 67 | −38.4% |
 **Non è solo beta.** Il B&H sul tail è +3.9% (BTC) e −38.4% (ETH), eppure le celle migliori
 fanno +37…+84% (BTC) con **long ~44–54%** (bilanciato long/short), e ETH +23.7% **mentre ETH
 scendeva −38%** (short corretti). Quindi c'è segnale direzionale genuino, non cattura di trend
 rialzista. Payoff asimmetrico: ~53% WR ma avgWin>avgLoss (BTC: +2.04% vs −1.63%).
 ### Fee-sweep (held-out)
 - `BTC W16000 H12 thr0.10`: 0.05%→+66.6 | **0.10%→+37.6** | 0.15%→+13.7 | 0.20%→−6.1.
  Sopravvive fino a ~0.15% RT, poi muore. Margine sottile.
 - `BTC W8000 H12 thr0.06`: positivo solo a 0.05%, già −35% a 0.10%. Fragile.
 - ETH e le celle a turnover medio: muoiono tra 0.10 e 0.15%.
 ### Stabilità per-anno (full walk-forward, BTC W16000 H24 thr0.10)
 `+11% (2020) / +188% (2021) / +14% (2022) / −38% (2023) / +13% (2024) / +75% (2025) / +7% (2026)`,
 CAGR full ~22%, ma **DD 56%** e fortissima concentrazione su 2021/2025 con un 2023 a −38%.
 ## Verdetto onesto — NON deployabile verso l'obiettivo
 1. **L'edge è reale ma minuscolo.** A differenza della vecchia libreria (artefatto puro), qui
   il segnale sopravvive a strict walk-forward, a fee 0.10% RT e batte il B&H sul tail. È un
   risultato genuino e va registrato: la direzione ML **non è morta**.
 2. **Ma è incompatibile col target.** €/giorno su €2000 = +0.26…+0.58 baseline (anche la stima
   rosea full-WF CAGR 22% → ~€1–3/g). Il target è **€50/g** → siamo ~100x sotto.
 3. **Fragilità**: vive solo a basso turnover (thr alto, H lungo, W grande), DD 23–56%,
   ritorni concentrati in pochi anni con un anno a −38%, e l'edge si assottiglia già a
   0.15% RT. Un singolo cambio di regime lo annulla.
 4. **ETH ≠ "specialmente buono"** (contrariamente all'indizio dello shape-ML precedente): qui
   ETH è più sottile e più rumoroso di BTC sull'held-out; l'unico merito è aver shortato
   correttamente il drawdown 2024-25.
 **Conclusione**: la logistic-regression walk-forward su feature di forma+momentum trova un
 debole edge **momentum direzionale a basso turnover** su BTC (più tenue su ETH), onesto e
 netto-fee, ma **troppo piccolo, troppo concentrato e troppo fee-sensibile** per essere
 deployato standalone. Al massimo un **componente** di un futuro ensemble, e solo nelle
 configurazioni a bassissimo turnover. Nessun config raggiunge, neanche lontanamente, i €50/g.
 ## Prossimi passi possibili (non eseguiti)
 - Provare **predizione di magnitudine/asimmetria** (large-up vs large-down) e position-sizing
  proporzionale alla confidenza, invece del semplice segno.
 - **GradientBoosting / feature non lineari** (flag `--gbm` predisposto) — ma attenzione
  all'overfit; il rischio è di "trovare" edge che il walk-forward onesto non conferma.
 - **Ensemble** del segnale ML a basso turnover con un filtro di regime (vol/trend) per tagliare
  il 2023. Ma serve dimostrare che il filtro non è scelto col senno di poi.
 - Restare scettici: finché €/g resta ~100x sotto target, l'ML da solo NON è la risposta.

 # 2026-06-19 — Track C: mean-reversion / range re-examination (HONEST) → DEAD
 Obiettivo: stabilire rigorosamente se **un qualunque** edge di mean-reversion / range a
 breve orizzonte sopravvive su BTC/ETH **certificati** (Deribit mainnet) con **ingresso
 eseguibile onesto**, oppure confermarne definitivamente la morte. Entrambi gli esiti sono
 validi; nessun risultato forzato.
 Tool: `scripts/research/trackC_meanrev.py` (self-contained, runnable), sopra l'harness
 onesto `src/backtest/harness.py` (direzione+prezzo decisi con dati ≤ `close[i]`, fill a
 `close[i]`, exit intrabar TP/SL da `i+1`, fee netto). Universo: BTC/ETH × {1h,15m,5m}.
 ## Cosa è stato testato (5 famiglie, ingresso onesto)
 - **ZFADE** — Bollinger/z-score fade: `z(close,lookback)` ≤ −thr → long, ≥ +thr → short.
  TP al mean mobile o a `tp_atr·ATR`; SL a `sl_atr·ATR`. **Entry a close[i]**, NON al tocco
  della banda (era proprio quello l'artefatto storico).
 - **RSI2** — RSI(2) oversold/overbought (+ variante con filtro trend SMA200).
 - **RETREV** — return reversal: fade del rendimento cumulato estremo (|z| > thr·σ).
 - **VWAP** — reversione sulla distanza dal VWAP rolling (in unità di σ della distanza).
 - **SESSION** — autocorrelazione next-bar per ora UTC (descrittivo).
 Metodologia applicata: OOS 65/35, griglia parametri su **entrambi** gli asset, fee-sweep
 {0, 0.5, 1.0, 1.5, 2.0} bps RT, cross-check liquidità (flat-bar O=H=L=C) e time-in-market.
 ## Sanity liquidità
 Flat-bar O=H=L=C: BTC/ETH 1h ≈ 0.01%, 15m 0.09–0.14%. Book vivo → l'eventuale edge NON
 potrebbe nascondersi in barre ferme (a differenza degli alt archiviati). Confermato pulito.
 ## Risultati — tutto negativo, su ogni asse
 **PASS 1 (screen 1h, fee 0.10% RT):** ogni famiglia OOS negativa su entrambi gli asset.
 Es. ZFADE z2/mean: BTC OOS −85%, ETH OOS −83%. RSI2 10/90: BTC −92%, ETH −96%.
 RETREV/VWAP idem. Win-rate spesso "alto" (RSI2 ~63%, VWAP ~64%) ma **perde lo stesso** →
 le poche perdite sono enormi, la reversione non paga il rischio + fee.
 **PASS 2 (griglia 1h):** ZFADE **0/18** celle con OOS>0 su entrambi; RSI2 **0/36**. La
 cella meno-peggio (ZFADE lookback20 z3) resta BTC −40% / ETH −33% OOS. Nessun sopravvissuto.
 **PASS 3 (fee-sweep, incl. fee=0 GROSS):** il colpo decisivo. **Anche a fee=0** (lordo)
 la z-fade è negativa: BTC full −74% / OOS −46%, ETH full −98% / OOS −48%. Quindi non è
 "morte da fee": **la direzione stessa della fade è sbagliata** sul feed pulito. Salendo le
 fee degrada monotòno fino a −100%.
 **PASS 4 (timeframe 5m/15m/1h):** più veloce = peggio. A 5m full −100% su entrambi
 (41.889 / 38.660 trade), €/giorno su 2000 ≈ −0.70/−0.75. Coerente con "molte operazioni =
 morte per fee", ma il PASS 3 mostra che il problema è a monte: niente edge nemmeno lordo.
 **PASS 5 (sessione UTC):** esiste una **debole** autocorrelazione negativa next-bar in
 poche ore (BTC 13h −0.166, 2h −0.154, 21h −0.129; ETH 13h −0.152, 4h −0.117), e una
 positiva alle 03h UTC (BTC +0.158, ETH +0.202 = ora "trending"). Struttura reale ma
 debolissima (|ρ|≤0.17): non sopravvive a fee + dimensionamento del rischio (lo conferma il
 fatto che tutte le versioni *tradate* perdono anche lorde).
 ## Verdetto
 **Nessuna** configurazione MR produce OOS netto>0 su entrambi BTC ed ETH a fee baseline.
 Più forte: **a fee zero la fade è già negativa** → l'edge MR storico (+201%/+1238% "OOS")
 era un **artefatto del feed contaminato** (wick fantasma testnet + entry su estremi mai
 scambiati), non una proprietà del mercato. Sul dato certificato, con ingresso eseguibile,
 la mean-reversion a breve orizzonte **non è un edge**: è morta sia lorda che netta.
 Coerente con la tesi del reset (`2026-06-19-deribit-history.md`, §3): FADE morto ogni anno.
 Track C chiusa come direzione di alpha. La debole struttura intraday-by-hour (PASS 5) è

 # 2026-06-19 — Track D: Robust walk-forward TREND PORTFOLIO (BTC+ETH), vol-targeted + leverage
 Follow-up to Track A. Thesis under test: trend-following's real value in crypto is **drawdown
 reduction** vs buy & hold (it sidesteps crashes), and that lower DD lets you apply **leverage** and
 **diversify** BTC+ETH into a deployable, risk-adjusted *earning* system — even if each single signal
 has modest Sharpe. Tool: `scripts/research/trackD_trendport.py` (run
 `uv run python scripts/research/trackD_trendport.py`).
 ## Method (honest, no look-ahead)
 Equity built directly from a **target-position series** (the harness's documented "build your own
 equity" path), NOT per-trade chaining:
 - `target[i]` decided with data **≤ close[i]**; **held during the next bar** (close[i]→close[i+1]).
 - `pnl[t] = target[t-1]·r[t]`, `r[t]=close[t]/close[t-1]-1` — positions **shifted +1 bar** ⇒ no leakage.
 - Fees on **turnover**: `0.05%/side·|target[t-1]-target[t-2]|` (0.10% RT baseline; swept 0.10–0.40% RT).
 - **Vol-targeting** (main lever): `target = direction · (target_vol / realized_vol)`, clipped to the
  leverage cap. `realized_vol` = annualized rolling std of past bar returns (30d window), ≤ close[i].
 - **Portfolio** = 50/50 BTC+ETH net-return series, rebalanced each bar on common timestamps.
 Leakage sanity check passed: an *oracle* target using next-bar sign explodes (10^119×) — proving the
 engine holds `target[i-1]` over bar `i` — while our signals (TSMOM blend, MA-slope, Donchian) only use
 `close[i]` and earlier. Zero-position equity = exactly 1.0.
 ## What was tested
 TSMOM multi-horizon blend (1/3/6-month-equiv on 1h bars), MA-slope (EMA200 slope), Donchian breakout
 with trailing channel stop — each vol-targeted, long-short **and** long-flat, per-asset and combined.
 Grid: target-vol × leverage-cap × horizon-set; explicit EARLY(2018-21)/LATE(2022-26) split;
 fee & leverage sweep; full per-year 2018-2026.
 ## Results — the honest picture
 **1) The thesis holds: massive DD reduction, and diversification helps.**
 | Strategy (50/50 port, tvol20%, LS) | CAGR | Sharpe | maxDD | volA |
 |---|---|---|---|---|
 | **B&H 50/50** | +48% | 0.92 | **77.8%** | 70% |
 | TSMOM 1-3-6m blend | +14.2% | **1.00** | **18.9%** | 14% |
 | MA-slope | +14.1% | 0.79 | 21.9% | 19% |
 | Donchian-trailing | +14.7% | 0.89 | 17.7% | 17% |
 Trend cuts maxDD from ~78% to ~18% while keeping a Sharpe **above** buy&hold (1.00 vs 0.92). The
 portfolio Sharpe (1.00) **beats both sleeves** (BTC 0.95, ETH 0.75) — diversification works as claimed.
 The **long-flat** variant is even cleaner: Sharpe **1.32**, maxDD **13.3%** (no short funding/borrow risk).
 **2) It is genuinely robust (not a lucky cell).**
 - *Per-year (headline LS):* every full year **positive** 2019-2025 (+19/+36/+19/+6/+2/+14/+4%) and 2026 +8%.
 - *Grid:* Sharpe ≈1.00 across **all** target-vol (10-40%) × leverage caps — flat plateau (vol-targeting
  just scales). DD scales ~linearly with target-vol (10%→DD10%, 40%→DD35%).
 - *Horizon-set:* every subset (1m/3m/6m/1-3m/3-6m/1-2-4m/2-4-8m) is **positive**; Sharpe 0.37→1.39.
  Shorter horizons (1m, 1-2-4m) score best (Sharpe 1.34-1.39) — a real plateau, not one combo.
 - *Fee:* survives to 0.40% RT (Sharpe 1.00→0.39, still positive at 4× baseline fee).
 **3) The honest caveat — most of the edge is the EARLY regime.**
 Walk-forward split, same param set both assets:
 - **EARLY 2018-2021:** CAGR +26%, Sharpe **1.63**, DD 18%.
 - **LATE 2022-2026:** CAGR +7.3%, Sharpe **0.57**, DD 19%.
 The signal is real and still net-positive every late year, but its quality **halved** post-2021
 (crypto vol compressed, trends choppier). This is the same warning Track A raised, now quantified: the
 edge is strongest 2019-2021 and merely *modest* in the 2022-26 regime.
 **4) Leverage is a red herring; target-vol is the real dial — and it costs DD linearly.**
 At tvol=20% on 60-80% crypto vol, positions stay **sub-1x** (avg gross 0.23×): the leverage cap
 **never binds**. To deploy real leverage you raise target-vol; Sharpe stays ~1.0, DD scales:
 | target_vol | avg gross | CAGR | Sharpe | maxDD |
 |---|---|---|---|---|
 | 20% | 0.23× | +14% | 1.00 | 19% |
 | 40% | 0.45× | +28% | 1.00 | 35% |
 | 60% | 0.68× | +40% | 1.00 | 48% |
 | 80% | 0.90× | +50% | 1.00 | 60% |
 | 100% | 1.12× | +58% | 0.99 | 69% |
 ## Verdict — is this a deployable earning system?
 **Yes as a risk-adjusted system; NO as a fast path to €50/day on €2000.**
 - This is the **first post-reset config that is genuinely robust**: Sharpe ~1.0 (long-flat 1.3),
  positive every year 2018-2026, robust across grid/horizon/fee, on both assets, on certified data,
  with honest no-look-ahead accounting. It is a real, deployable trend portfolio and a clear
  improvement over Track A's lucky single cells. The thesis (DD reduction → leverageable, diversifiable)
  is **confirmed**.
 - **But the earnings are modest.** Headline (tvol20%, 2x cap, LS): CAGR **+14.2%**, DD 19% ⇒ steady-state
  **~€0.73/day on €2000**. To average **€50/day at this CAGR you need ~€137k capital**, not €2000.
 - **Leverage can't close the gap cheaply.** Pushing target-vol to 80% gives CAGR ~50% (DD **60%**) — and
  at €2000, 50%/yr is still only ~€2.7/day in steady state. Reaching €50/day in 1-2 years from €2000
  would require both heavy leverage (DD 60-70%, near-ruin) **and** lucky path — not a sane plan.
 - **Regime risk:** the edge is much weaker post-2021 (Sharpe 0.57 LATE). Deploy sized for the LATE
  regime, not the EARLY one.
 **Recommendation:** treat this as the **core risk engine** (compounding ~14%/yr at DD<20%, or
 long-flat ~16%/yr at DD 13%), deployable now at low size to validate live execution. It grows €2000,
 but to *€50/day* the lever is **capital + time**, not leverage. Realistic near-term: ~€0.7-1.5/day on
 €2000; €50/day needs ~€70-140k or a second uncorrelated edge stacked on top.

 ---
 ## PART 1 — Relative value (spread BTC↔ETH, 1h, market-neutral)
 **Premessa strutturale.** BTC/ETH log-ret 1h sono correlati **0.84**. Con due soli asset
 l'unica struttura tradabile è lo **spread**. E con due asset, *"long il più forte / short il
 più debole"* (XS-momentum) è **algebraicamente identico** a *"trada il trend del ratio
 ETH/BTC"* — infatti nel codice (A) e (B) producono numeri identici. Sono lo stesso edge.
 **Lead-lag: nullo.** `corr(rB[i], rE[i+1]) = −0.018`, `corr(rE[i], rB[i+1]) = −0.007`,
 autocorrelazioni −0.01..−0.02. Nessun potere predittivo cross-asset → lead-lag **non**
 perseguito come sleeve (sarebbe rumore moltiplicato per le fee).
 **(A/B) XS momentum / ratio trend (griglia N∈{24,72,168,336}, hold∈{6,24,72}):**
 - Solo **4/12 celle** OOS net-positive, e sparse (N24/h24, N24/h72, N72/h72, N168/h24).
 - Le celle FULL forti (N168/h24: +150% full, Sharpe 0.68, DD 27%) hanno **OOS debole**
  (+11%, Sh 0.30). La migliore per OOS-Sharpe è N24/h24 (OOS Sh 0.31, OOS net +11%).
 - **Fee sweep (N24/h24):** gross (0bp) FULL +356%/OOS +74% Sh 1.20 → a 1.0bp/gamba FULL +27%/
  OOS +11% Sh 0.31 → **muore già a 1.5bp/gamba** (OOS −11%). Margine fee sottilissimo.
 - **Per-anno** concentrato sui grandi movimenti del ratio 2020-2021 (e 2024), piatto/negativo
  altrove (2022 −9%, 2023 −19%, 2025 −6%, 2026 −16%). Non è un altopiano: è un edge debole,
  fee-sensibile, regime-dipendente.
 **(C) Ratio mean-reversion (z-fade di log(ETH/BTC)):** negativa ovunque (es. lb168/zin2.0:
 FULL −85%, OOS −44%, Sh −1.56). Coerente con Track C: anche sullo spread la MR a breve non è
 un edge sul dato pulito.
 **Verdetto PART 1:** esiste un **debole** edge di relative-value (XS-momentum ≡ ratio-trend),
 net-positivo OOS solo in alcune celle, Sharpe OOS ~0.3, che **muore a ~1.5bp/gamba** ed è
 concentrato in pochi anni. È **reale ma marginale** — degno di entrare in un ensemble come
 sleeve diversificante, non come strategia standalone. La sua virtù: è **quasi scorrelato**
 dagli edge direzionali (vedi sotto).
 ---
 ## PART 2 — Ensemble (3 sleeve residui in UN portafoglio)
 Sleeve combinati (gross 1 ciascuno, equal-weight 1/N → gross totale ~1):
 - **S1 = BTC-ML** (Track B, cella onesta a basso turnover W16000 H24 thr0.10, 1h).
 - **S2 = BTC-Trend** (Track A, l'unica cella trend robusta cross-asset: Donchian N=200 H=12).
 - **S3 = Relative-value** (PART 1, miglior cella OOS: XS-momentum N=24 hold=24).
 **Finestra comune attiva** (dove tutti e 3 sono live, dopo il warmup ML): 2020-06 → 2026-06,
 52.636 barre.
 ### Matrice di correlazione degli sleeve (ret per-barra, finestra comune)
 |          | S2_trend | S3_relval | S1_ml  |
 |----------|----------|-----------|--------|
 | S2_trend | +1.000   | +0.010    | −0.063 |
 | S3_relval| +0.010   | +1.000    | −0.010 |
 | S1_ml    | −0.063   | −0.010    | +1.000 |
 → **Sleeve quasi perfettamente scorrelati** (|ρ| ≤ 0.06). In teoria, terreno ideale per la
 diversificazione.
 ### Per-sleeve (finestra comune, scala $ uguale)
 | sleeve    | net   | Sharpe | maxDD | €/g(2k) |
 |-----------|-------|--------|-------|---------|
 | S2_trend  | +5%   | +0.15  | 34%   | +0.04   |
 | S3_relval | +8%   | +0.16  | 41%   | +0.07   |
 | **S1_ml** | +382% | **+0.87** | 56% | +3.51   |
 ### Ensemble
 | portafoglio          | net   | Sharpe | maxDD | CAGR  | €/g(2k) |
 |----------------------|-------|--------|-------|-------|---------|
 | best single (S1_ml)  | +382% | +0.87  | 56%   | +30%  | +3.51   |
 | **EQUAL-WEIGHT 1/N** | +109% | **+0.83** | **30%** | +13% | +1.00 |
 | inverse-vol (IS wts) | +76%  | +0.70  | 29%   | +10%  | +0.69   |
 | EQ-WEIGHT **OOS**(65/35)| +32% | **+1.02** | **12%** | +14% | +0.83 |
 Per-anno equal-weight: 2020 +16%, 2021 +50%, 2022 +2%, **2023 −13%** (vs −38% dell'ML da
 solo!), 2024 +18%, 2025 +19%, 2026 −3%. **Molto più liscio**, niente anno-catastrofe.
 ### La diversificazione aiuta? Sì sul rischio, NO sul rendimento risk-adjusted
 - **Sharpe:** ensemble 0.83 vs best-single 0.87 → **non batte** il miglior sleeve singolo.
 - **maxDD:** ensemble **30%** vs best-single 56% → **dimezzato**. E OOS 12% vs ML-solo molto
  più profondo. Per-anno senza il −38% del 2023.
 - **Risk-matched** (levare l'ensemble 1.84x per pareggiare il 56% DD dell'ML): €/g +2.23
  contro €/g +3.51 dell'ML da solo → a pari drawdown l'ensemble rende **MENO** (ratio 0.64).
 **Perché?** Gli sleeve sono scorrelati ma **enormemente diseguali** (Sharpe 0.87 vs 0.15 vs
 0.16). L'equal-weight 1/N "annacqua" l'unico sleeve forte con due deboli: la matematica
 della diversificazione alza lo Sharpe solo se gli sleeve sono di *qualità comparabile*. Qui
 non lo sono, quindi 1/N non può superare il singolo migliore. Pesare verso l'ML (quality-
 weighting) converge banalmente a "esegui solo l'ML" — e sarebbe in-sample.
 **Il guadagno vero dell'ensemble è la ROBUSTEZZA, non il rendimento:** stesso Sharpe del
 miglior sleeve a **metà del drawdown**, per-anno molto più stabile, niente dipendenza da un
 singolo modello/regime (l'ML da solo concentra tutto in 2021/2025 con un −38% nel 2023). Per
 chi deve *sopravvivere*, l'ensemble è preferibile; per chi massimizza il rendimento a pari
 rischio, l'ML puro vince di un soffio.
 ---
 ## Verdetto onesto — è un motore da €50/giorno? NO.
 1. **Relative-value:** edge debole, reale ma marginale (Sharpe OOS ~0.3), fee-sensibile
   (muore a 1.5bp/gamba), concentrato 2020-2021/2024. Utile **solo** come sleeve scorrelato.
   Lead-lag e ratio-MR: nulli/negativi.
 2. **Ensemble:** gli sleeve sono **quasi scorrelati** (|ρ|≤0.06) — risultato genuino e bello.
   L'ensemble equal-weight ottiene **Sharpe ~0.83 a metà del drawdown** del miglior sleeve e
   un per-anno molto più liscio. **Ma NON alza il tetto risk-adjusted** (a pari DD rende meno
   dell'ML puro) perché un solo sleeve domina.
 3. **Distanza dal target:** ensemble **€1.00/giorno su €2000** (best single €3.51 ma a DD
   56% e concentrato). Il target è **€50/giorno → ~50x sotto** (l'ML puro ~14x sotto ma con
   rischio/concentrazione inaccettabili). Levare per colmare il gap moltiplica il drawdown
   ben oltre il tollerabile (1.84x già porta al 51% DD per ~€2.2/g).
 **Conclusione:** la sintesi di Track E conferma la fotografia dei track A/B/C — esistono
 **edge residui deboli ma reali e scorrelati** su BTC/ETH. Combinarli in un ensemble **migliora
 la robustezza** (DD dimezzato, per-anno stabile, niente single-point-of-failure) ma **non crea
 rendimento dal nulla**: il sistema combinato rende ~€1/giorno su €2000, ~50x sotto l'obiettivo,
 e non è un motore dispiegabile. Il miglior uso pratico dei risultati: se un giorno si tradasse,
 l'ensemble equal-weight (ML + trend + relative-value) è la forma **più onesta e meno fragile**
 del poco edge disponibile — ma serve un edge **di un'altra magnitudine** per avvicinare i €50/g.
 ## Prossimi passi possibili (non eseguiti)
 - Cercare uno sleeve **di qualità comparabile all'ML** (Sharpe ≥0.5 indipendente) — solo
  allora 1/N alzerebbe lo Sharpe oltre il singolo. Senza, l'ensemble resta solo "risk smoother".
 - Relative-value su **timeframe diversi** del ratio (giornaliero?) o con **position sizing**
  proporzionale alla forza del segnale, restando scettici sul fee-margin sottile.
 - Non aumentare la leva per inseguire €50/g: il DD esplode prima del rendimento.

 # Track F — Calendar seasonality (hour-of-day / day-of-week) on BTC & ETH
 **Data:** 2026-06-19 · **Script:** `scripts/research/trackF_seasonality.py`
 **Dati:** Deribit mainnet certificati, BTC/ETH 1h UTC. Fee baseline 0.10% RT (`fee_side=0.0005`).
 ## Domanda
 Esiste un edge di calendario *sistematico e tradeable* (ora del giorno, giorno della
 settimana, interazione ora×giorno) su BTC ed ETH, netto fee, OOS, per-anno, su entrambi gli asset?
 ## Metodologia (anti-overfit, anti-leakage)
 - `ret[i]=close[i]/close[i-1]-1` è noto a `close[i]`; una posizione decisa a `close[i]` guadagna
  `ret[i+1]`. La statistica che decide il trade usa **solo barre ≤ i** (mai la barra tradata né futuro).
 - **Tradeable test onesto = ADAPTIVE EXPANDING sign**: a `close[i]` guardo il bucket di calendario
  della barra `i+1` (il clock è noto, zero look-ahead) e prendo il **segno della media passata** di
  quel bucket (espandente, warmup-gated). Long-flat o long-short. Fee solo su `|Δposizione|`.
  È l'analogo onesto di "tradare il seasonal": i dati scelgono il segno di ogni bucket **dal vivo**.
 - Tabelle descrittive per-ora/per-giorno split IS(65%)/OOS(35%) come diagnostica.
 - Regola discreta ottimizzata in-sample (entra a ora H, tieni W barre, dir migliore) mostrata solo
  per **esporre il gap IS→OOS** (384 celle testate/asset).
 - Benchmark **buy-and-hold** come controllo del long-bias.
 ## Risultati
 ### 1. Descrittive (bp/barra, IS vs OOS)
 - **Hour-of-day:** sign-agreement IS/OOS solo **12/24 (BTC)** e **8/24 (ETH)** → caso. Le ore "US
  close" 21:00–22:00 UTC sono positive in entrambi gli split su entrambi gli asset (l'unico pattern
  con un minimo di coerenza), ma il resto è rumore che cambia segno tra IS e OOS.
 - **Day-of-week:** più stabile. **Giovedì negativo** su BTC ed ETH in IS *e* OOS; Lun/Mer positivi.
  Sign-agreement 6/7 (BTC), 5/7 (ETH).
 ### 2. Adaptive expanding-sign (il test tradeable)
 | Strategia | BTC Sharpe | ETH Sharpe | Note |
 |---|---|---|---|
 | HOUR long-short | **−5.39** | **−4.04** | DD 100%. Annientata dalle fee. |
 | HOUR long-flat | −2.92 | −2.09 | DD 100%. Idem. |
 | DOW long-short | +0.64 | +0.83 | DD 82–84%, −66% nel 2022 |
 | DOW long-flat | +0.81 | +0.96 | DD 75–78%, −64/−66% nel 2022 |
 | HOUR×WEEKDAY (168 buckets) | −5.05 | −3.96 | DD 100%. Overfit puro + fee. |
 ### 3. Il controllo che smonta il DOW — **buy-and-hold**
 - BTC buy-hold: **Sharpe 0.79, CAGR 34.9%, DD 77%**  → DOW long-flat: Sh 0.81, CAGR 34.2%, DD 77.5%.
 - ETH buy-hold: **Sharpe 0.84, CAGR 42.4%, DD 81%** → DOW long-flat: Sh 0.96, CAGR 52.7%, DD 74%.
 - Il DOW long-flat è **long il 78% del tempo** (`mean_pos≈+0.78`). È **buy-and-hold travestito**:
  guadagna perché crypto sale, non perché esiste un edge di giorno. Lo "skip del giovedì" aggiunge
  pochissimo e non giustifica un deploy.
 ### 4. Fee sweep (HOUR long-short adaptive)
 A fee **0%**: Sh +0.61 (BTC) / +0.80 (ETH) — solo long-drift. A 0.10% RT: **−5.4 / −4.0**. Turnover
 **~8.000 flip/anno** (segno orario instabile, cambia quasi ogni barra) → morte istantanea per fee.
 Le strategie hour-of-day sono ad alta frequenza per costruzione: le fee sono di prim'ordine e le
 uccidono.
 ### 5. Regola discreta ottimizzata in-sample (trappola multiple-testing)
 - BTC: best IS H=05 hold=24h dir=+1 → **IS Sh +4.25 → OOS Sh +1.47** (+3.7 bp/trade).
 - ETH: best IS H=13 hold=24h dir=+1 → **IS Sh +7.35 → OOS Sh +0.90** (+3.2 bp/trade).
 - Collasso IS→OOS classico. Inoltre "hold 24h dir+1" = ancora **long-bias** (entra una volta/giorno
  e tiene 24h ≈ sempre long). Il margine OOS (~3 bp/trade su 10 bp RT) è marginale e fragile.
 ## Multiple-testing
 199 celle di calendario/asset (24 ore + 7 giorni + 168 ora×giorno) + 384 (H,W,dir)/asset. Con così
 tante celle, bucket "significativi" spuri sono **garantiti**. Filtri applicati: segno scelto dal vivo
 su soli dati passati, deve reggere OOS, per-anno, e su **entrambi** BTC ed ETH.
 ## Verdetto — **SPURIO / NON deployable**
 - **Nessun edge di calendario netto-fee robusto** su BTC ed ETH.
 - **Hour-of-day:** morto (fee + segno instabile). L'unica regolarità (US-close 21–22 UTC positiva) è
  troppo debole e non sopravvive al turnover.
 - **Day-of-week:** l'unico risultato "positivo" è **long-bias mascherato** (≈ buy-and-hold,
  Sharpe ~0.8–0.96 < trend portfolio 1.32, DD 75–84% rovinoso, −65% nel 2022). Non è un edge
  seasonal sfruttabile; è esposizione direzionale al drift di crypto.
 - **Hour×weekday:** overfit puro (IS −3.6 → OOS −8.0).
 - Coerente con la lezione del progetto: dove l'unica "direzione" che funziona è essere long, non c'è
  alpha di timing — c'è beta. Il trend portfolio (TP01) cattura quel beta in modo vol-targeted e
  con DD ~12%, infinitamente meglio di qualunque regola di calendario qui.
 **Azione:** track F chiuso negativo. Non aggiungere nulla al portafoglio. Il soffitto Sharpe ~1.3 su

 **continuano** (trend) o **rientrano** (fade)?
 ## No look-ahead (garanzie)
 - Livelli prior-day/week costruiti aggregando a barre giornaliere/settimanali (UTC) e poi
  **`shift(1)`** sul frame del periodo *chiuso*: il periodo corrente vede solo il precedente
  totalmente chiuso. Mai "oggi"/"questa settimana" nel livello.
 - Opening-range usato **solo** sulle barre dopo la chiusura della finestra di apertura.
 - Direzione + prezzo decisi a `close[i]`, fill a `close[i]`. Mai entry sul livello esatto intrabar.
 - Bug iniziale corretto: mismatch tz-aware vs tz-naive nel mapping dei livelli (dava 0 trade).
 ## Risultati (1h, fee 0.10% RT, leva 1x, OOS 65/35)
 ### Continuation vs FADE — il verdetto è netto
 | Regola (PD = prior-day) | BTC OOS | ETH OOS | Sharpe OOS |
 |---|---|---|---|
 | **PD-high CONT (long su rottura max ieri)** | **+25%** | **+16%** | +0.5 / +0.3 |
 | PD-high FADE | **−68%** | **−68%** | −1.6 / −1.2 |
 | PD-low CONT (short su rottura min ieri) | −33% | −60% | −0.5 / −0.8 |
 | PD-low FADE | −36% | −8% | −0.6 / +0.1 |
 - **I breakout CONTINUANO, non rientrano.** Il lato FADE è robustamente **negativo** su entrambi
  gli asset (sia high che low), su prior-day, prior-week e opening-range. Conferma diretta della
  tesi del reset: la mean-reversion / fade è morta su dati certificati.
 - **Asimmetria long-only:** funziona solo la rottura del **massimo** (long), non quella del
  **minimo** (short). Cioè non è un edge di breakout *simmetrico/direzione-neutro*: è cattura del
  **drift/trend rialzista** del cripto. La PD-low-cont (short sui breakdown) perde perché in questo
  campione il cripto sale.
 ### Grid robustness (PASS 6) — survivor = OOS>0 su ENTRAMBI
 - **PD-high CONT: 3/3 celle** (buffer 0/0.1%/0.3%) positive OOS su BTC **e** ETH → robusto al buffer.
 - PD-high fade, PD-low cont/fade, OR-fade: **0 survivor**.
 - **OR-cont:** positiva solo su ETH, negativa su BTC su tutte le finestre (3/6/8/12h) → artefatto
  mono-asset, scartato dalla regola "entrambi".
 ### Anchor-hour sweep (PASS 5) — non è un'ora fortunata
 PD-high cont positiva su **21/24** ore UTC (BTC) e **20/24** (ETH). Non dipende da un singolo
 anchor → coerente con un edge reale (ma vedi sotto: è beta di trend).
 ### Fee sweep + per-anno (PD-high cont, full sample)
 ```
 BTC  RT%: 0.00→+571  0.05→+289  0.10→+126  0.15→ +31  0.20→ −24   (OOS: +84/+52/+25/+3/−15)
 ETH  RT%: 0.00→+1754 0.05→+1012 0.10→+567  0.15→+299 0.20→+139   (OOS: +67/+39/+16/−3/−19)
 BTC per-anno: 2019 +39  2020 +104  2021 +7  2022 −42  2023 +24  2024 +27  2025 −16  2026 +3
 ETH per-anno: 2020 +164 2021 +160 2022 +7  2023 +1   2024 +12  2025 −4  2026 +7
 Sharpe full: BTC +0.48 (maxDD 55%, €/d 2k +0.88) · ETH +0.86 (maxDD 34%, €/d 2k +4.27)
 ```
 - **Fee-fragile:** alla baseline 0.10% RT sopravvive (OOS +25/+16%), ma muore già a ~0.15-0.20% RT.
  Margine di fee sottile (≈1.5x baseline e l'edge sparisce su OOS). ~1000-1100 trade in 8 anni.
 - **Drawdown enormi** (BTC 55%) e anni negativi (2022 −42% BTC, 2025 −16%).
 ## Verdetto
 - **Sì, esiste un edge net-positivo OOS su entrambi gli asset:** *PD-high continuation* (long
  quando `close` supera il massimo di ieri, exit a fine giornata UTC). Robusto al buffer e
  all'anchor-hour. **MA non è deployabile come miglioramento:**
  1. È **long-only drift capture**, non un breakout simmetrico (il lato short fallisce) → è una
     versione **più debole e ridondante** del Trend Portfolio TP01 (Sharpe 0.48-0.86 vs 1.32).
  2. **Fee-fragile** (muore a ~1.5x la fee baseline) e con **drawdown** molto peggiori.
 - **Il contributo scientifico vero è la conferma della direzione:** sui dati certificati i
  breakout di livello-calendario **CONTINUANO**; il fade è morto (negativo robusto su PD/PW/OR,
  entrambi gli asset). Nessuna sorpresa mean-reversion nascosta nei livelli giornalieri/settimanali.
 - **Niente di nuovo da mettere in produzione.** TP01 resta la strategia vincente; i breakout
  prior-period non aggiungono Sharpe (stessa beta di trend, peggio eseguita).

 # Track H — Volume, Range & Volatility-Regime signals (BTC/ETH, certified, >=12h)
 **Date:** 2026-06-19
 **Script:** `scripts/research/trackH_volume_vol.py` (runnable, self-contained)
 **Question:** does any volume / range / volatility-regime signal ADD to the deployed winner
 TP01 (vol-targeted trend portfolio, 12h, Sharpe ~1.32) — i.e. net-positive OOS on BOTH BTC &
 ETH AND uncorrelated (|corr|<~0.3) — OR work as a regime filter that lifts TP01's Sharpe / cuts
 its DD?
 ## Method (honest)
 - Same causal per-bar engine as `TrendPortfolio.net_returns`: build a continuous TARGET decided
  with data `<= close[i]`, HOLD it during bar `i+1` (`pos_held[t]=target[t-1]`), gross = pos×ret,
  fee on `|Δpos|`. Identical in spirit to `harness.backtest_signals` (decide≤close[i], fill at
  close[i]); two discrete signals cross-checked through `backtest_signals` directly.
 - All features (volume z-score, OBV, ranges, realized vol) use prior/rolling windows shifted so
  bar `i` sees only `<= i`. 12h/1d resampled from certified 1h via `resample_tf` (label='left'),
  consumed index-based with the +1 hold → no open-label leak.
 - Fee 0.10% RT baseline + sweep 0.00–0.40% RT. OOS 65/35 + per-year. Grid on BOTH assets.
  Turnover and correlation-to-TP01 reported for every signal.
 - **>=12h only** (12h + 1d). Sub-12h excluded per the standing lesson (fees + HF-noise overfit +
  the 4h open-label look-ahead trap).
 ## Signals tested
 VT-long (volatility-managed long), VolBreakout (volume-z-confirmed Donchian), OBV-trend,
 VW-mom (volume-weighted momentum), RangeExpand (range-expansion breakout), NR7-break
 (narrowest-range breakout), DeclVolRev (declining-volume fade/reversal). Plus regime overlays on
 TP01: keep-low-vol, keep-high-vol, vol-managed ×1.5, OBV-up confirmation.
 ## Results (12h headline, fee 0.10% RT)
 | signal | corr→TP01 | OOS Sharpe BTC/ETH | note |
 |---|---|---|---|
 | VT-long | 0.66 / 0.69 | 0.80 / 0.14 | trend-in-disguise; weak OOS ETH |
 | VolBreakout | 0.69 / 0.71 | 0.54 / 0.49 | profitable but correlated |
 | OBV-trend | 0.61 / 0.63 | 0.96 / 0.68 | profitable but correlated; turnover ~75/yr |
 | VW-mom | 0.64 / 0.67 | 0.98 / 0.74 | basically TSMOM; correlated |
 | RangeExpand | 0.48 / 0.49 | 0.37 / 1.04 | lower corr but BTC weak; ETH negative on 1d |
 | NR7-break | 0.48 / 0.49 | 0.79 / 0.02 | fails OOS on ETH |
 | DeclVolRev | -0.15 / -0.11 | -1.15 / -0.44 | **negative even at zero fee** |
 Grid robustness (12h, % cells positive full+OOS on both assets): VW-mom 100%, VT-long 100%,
 VolBreakout 96%, RangeExpand 96%, OBV-trend 75% — but the robust ones are precisely the ones
 that are highly correlated to TP01. Fee sweep: trend-family signals survive to 0.40% RT;
 DeclVolRev gets worse with fees (it trades constantly).
 ## Regime filters on TP01 (12h, 50/50 portfolio)
 | variant | full Sharpe | OOS Sharpe | maxDD | CAGR | turn/y |
 |---|---|---|---|---|---|
 | **TP01 baseline** | **1.32** | 0.90 | 13.3% | 16.2% | 11.5 |
 | × keep LOW-vol | 0.94 | 1.11 | 14.1% | 7.7% | 9.5 |
 | × keep HIGH-vol | 0.98 | 0.18 | 9.9% | 7.9% | 4.9 |
 | × vol-managed ×1.5 | 1.33 | 0.96 | 17.9% | 18.1% | 15.4 |
 | × OBV-up only | 1.49 | 1.04 | 10.1% | 14.4% | 18.2 |
 OBV-up filter across EMA span: full Sharpe 1.49–1.52 (span 15–30), DD 7–10%, but OOS gain is
 marginal (0.90→1.04 at span 30) and fades for span≥45 (OOS 0.69–0.73). It cuts ~2pp CAGR and
 raises turnover ~60%.
 ## Verdict (honest)
 - **No uncorrelated additive edge exists.** Every *profitable* volume/range/vol signal is trend
  in disguise (corr 0.61–0.75 to TP01) → cannot raise the 50/50 portfolio Sharpe. The genuinely
  lower-corr signals (RangeExpand, NR7 ~0.48) fail OOS on at least one asset.
 - **Mean-reversion / declining-volume fade is dead** — negative net AND at zero fee on both
  assets. Reconfirms the v2.0.0 contamination lesson; MR is not a real edge on certified data.
 - **Vol-regime gating hurts** (keep-low / keep-high both drop Sharpe to ~0.95). The vol-managed
  overlay is Sharpe-neutral but DD-worse.
 - **The only non-harmful overlay is OBV-up trend-confirmation:** it cuts DD (13.3%→10.1%) and
  nudges full Sharpe to ~1.49, but it is trend double-confirmation (de-risking), not new alpha;
  it costs CAGR, raises turnover, and the OOS Sharpe gain is within noise and span-sensitive. It
  is worth keeping in mind as a **defensive DD overlay**, not as a Sharpe improver.
 - **Bottom line:** the ~1.3 portfolio-Sharpe ceiling on BTC/ETH-only **holds**. TP01 stays the
  deployable winner. Volume/range/vol add nothing uncorrelated.

 # Track I — Alternative momentum formulations + long-horizon reversal (2026-06-19)
 **Script:** `scripts/research/trackI_momentum_reversal.py` (self-contained, runnable).
 **Universe:** BTC & ETH only. **TF:** 12h + 1d (sub-12h excluded by rule). **Harness:** identical
 honest machinery to TP01 — direction decided `<= close[i]`, positions held next bar (`pos_held[1:]
 = tgt[:-1]`), vol-target by inverse PAST-ONLY realized vol (target 20%, lev cap 2x), NET fee 0.10%
 RT on turnover, 50/50 BTC+ETH. OOS 65/35 + per-year + fee sweep (0.00–0.40% RT). Correlation to
 TP01 net returns reported for every candidate.
 ## Goal
 (A) A momentum formulation that BEATS or DIVERSIFIES the canonical 1-3-6m sign-blend (TP01,
 Sharpe ~1.32). (B) Does the classic LONG-HORIZON REVERSAL (fade ~12m winners) give an
 uncorrelated positive overlay?
 ## PART A — momentum formulations (12h, long-flat, vs TP01 Sharpe 1.32 / OOS 0.90 / DD 13.3%)
 | formulation | Sharpe | IS | **OOS** | CAGR | maxDD | corr→TP01 | BTC | ETH |
 |---|---|---|---|---|---|---|---|---|
 | baseline sign-blend 1-3-6m | 1.32 | 1.54 | 0.90 | +16% | 13.3% | 1.00 | 1.15 | 1.10 |
 | (i) z-score cum-return (tanh) | **1.35** | 1.63 | 0.85 | +12% | **8.4%** | 0.96 | 1.30 | 1.00 |
 | (ii) risk-adjusted momentum | 1.27 | 1.49 | 0.84 | +13% | 9.5% | 0.97 | 1.21 | 1.00 |
 | (iii) EMA-cross trend | 0.81 | 0.91 | 0.62 | +11% | 25.1% | 0.85 | 0.89 | 0.53 |
 | (iii-b) MACD (calendar spans) | **1.50** | **1.87** | 0.74 | +22% | 17.7% | 0.69 | 1.30 | 1.32 |
 | (iv) Donchian breakout | 1.10 | 1.36 | 0.57 | +17% | 25.0% | 0.86 | 1.08 | 0.82 |
 | (v) acceleration (Δ-momentum) | 1.28 | 1.82 | 0.35 | +14% | 14.2% | 0.66 | 1.25 | 0.81 |
 | (vi) 12-1 skip momentum | 0.67 | 0.79 | 0.47 | +9% | 24.5% | 0.68 | 0.70 | 0.49 |
 Results are essentially identical at 1d. Read-out:
 - **Nothing cleanly beats the sign-blend OOS on both assets.** The headline-Sharpe leaders are
  artefacts of in-sample fit: **MACD** posts IS 1.87 but OOS collapses to 0.74 (gap = overfit) with
  a worse DD (17.7%); **acceleration** IS 1.82 → OOS **0.35** (worst OOS decay of all). Both fail.
 - **(i) z-score continuous momentum** is the one mild, honest refinement: Sharpe 1.35 (≈baseline)
  but **maxDD 8.4% vs 13.3%** — the continuous score scales down position when the cumulative move
  is statistically small, de-risking the tails. OOS 0.85 (slightly below baseline 0.90), CAGR drops
  16%→12%. It's a smoother sibling of TP01, **not a new edge** (corr 0.96).
 - (vi) 12-1 skip (classic equity "12-1" momentum) **does NOT help crypto**: skipping the recent
  month removes the strongest part of the signal here → Sharpe 0.67, corr 0.68. Crypto momentum
  lives in the recent window, opposite to the equity stylised fact.
 - Breakout/Donchian and EMA-cross are strictly worse (high DD, weak OOS).
 ## PART B — long-horizon reversal (fade past winners), 12h
 Long-short reversal (short ~12/18/24m winners, long losers, vol-targeted):
 | reversal LS | Sharpe | OOS | CAGR | maxDD | corr→TP01 |
 |---|---|---|---|---|---|
 | 12m | -0.77 | -1.15 | -14% | 73% | -0.51 |
 | 18m | -0.36 | -0.75 | -8% | 58% | -0.47 |
 | 24m | **+0.04** | -0.07 | -1% | 43% | **-0.32** |
 | 12-18-24m | -0.46 | -0.72 | -8% | 57% | -0.54 |
 - **Long-horizon reversal is NOT a standalone edge.** Standalone it LOSES money (12m/18m strongly
  negative; only 24m is ~flat at Sharpe 0.04, OOS −0.07, and even that fails "net-positive OOS on
  both assets": BTC +0.10 / ETH −0.03). Fading crypto winners over a year just shorts the trend.
 - It IS genuinely negatively correlated to TP01 (24m: corr −0.32; 12-18-24: −0.54), as expected
  (it's the opposite sign of medium-term momentum).
 - **Momentum + reversal blend** (long 1-6m momentum, brake on very-long extension): the variant
  `mom(1-3-6) − 0.5·rev(12-24)` is the most interesting single-strategy result — Sharpe **1.38**,
  **OOS 0.98** (> baseline 0.90), **maxDD 10.6%** (< 13.3%), both assets positive (BTC 1.25/ETH
  1.05), corr 0.91, fee-robust (1.43→1.22 across 0.00–0.40% RT). CAGR drops 16%→12%. It is TP01
  with a long-term-extension brake: a modest *risk-adjusted* improvement, not more return.
 ## COMBINED — TP01 + best diversifier (blend net returns)
 TP01 alone: Sharpe 1.321, CAGR +16%, maxDD 13.3%, OOS 0.90.
 | combo | Sharpe | CAGR | maxDD | OOS | corr |
 |---|---|---|---|---|---|
 | TP01 + 20% reversal-24m (LS) | **1.411** | +13% | 11.5% | **1.06** | -0.32 |
 | TP01 + 30% reversal-24m (LS) | 1.366 | +12% | 11.8% | 1.06 | -0.32 |
 | TP01 + 20% reversal-12-18-24 (LS) | 1.350 | +11% | 10.6% | 0.84 | -0.54 |
 | TP01 + 50% z-score | 1.348 | +14% | 9.5% | 0.89 | +0.96 |
 - Adding a small slice of **reversal-24m long-short** lifts portfolio Sharpe 1.32→1.41 and OOS
  0.90→1.06 while cutting DD to 11.5%. **But be skeptical:** the overlay is a ~zero-mean stream
  (standalone Sharpe 0.04). The benefit is almost entirely **variance reduction from the negative
  correlation, not added alpha** — and it COSTS return (CAGR 16%→13%). With a true-zero-edge
  diversifier this Sharpe bump is fragile (it leans on the −0.32 correlation persisting OOS, and the
  OOS sample is one 2022-24 crypto cycle). I would NOT deploy capital on a standalone-losing sleeve
  to chase a 0.09 Sharpe point that is really de-risking.
 ## Fee sweep (12h portfolio Sharpe)
 baseline 1.37→1.18, z-score 1.38→1.24, MACD 1.52→1.45 (lowest turnover), blend 1.43→1.22,
 reversal-24m 0.07→−0.02 (0.00→0.40% RT). All trend formulations survive realistic fees; reversal
 has no positive margin to survive on.
 ## VERDICT (honest)
 - **Is there a momentum formulation that beats the 1-3-6m sign-blend? No — not OOS, not on both
  assets.** MACD/acceleration look better in-sample but decay OOS (overfit + higher DD). The only
  honest refinement is **continuous z-score momentum**, which matches the Sharpe with materially
  lower drawdown (8.4% vs 13.3%) — a smoother variant of the SAME edge, not a new one (corr 0.96).
 - **Does long-horizon reversal give an uncorrelated positive overlay? No, not a real one.** It is
  uncorrelated/negatively-correlated (good) but **not positive** standalone (it loses, or at best is
  flat at 24m and fails the both-assets bar). The combined-Sharpe lift (→1.41) is variance reduction
  from a near-zero-mean stream and sacrifices CAGR — fragile, not bankable alpha.
 - **The ~1.3 structural Sharpe ceiling on BTC/ETH-only holds.** TP01 remains the deployable winner.
  If anything, swap the sign-blend for the **z-score continuous score** (or the `mom − 0.5·rev`
  brake) for a lower-DD profile at equal Sharpe — a risk-management tweak, not a return upgrade.

 # 2026-06-19 — Strato trend multi-asset sui 52 alt: RIDONDANTE col trend di TP01
 Tentativo: aggiungere un terzo sleeve = TSMOM (stessa logica TP01 CANONICAL, long-flat vol-target)
 applicato a OGNI alt dei 52 Hyperliquid certificati, equal-weight ragged. Idea: trend più
 diversificato che diversifichi TP01 (BTC/ETH). `scripts/portfolio/trend_multiasset.py`.
 ## Esito: ridondante e peggiore
 - **TREND-52 standalone**: FULL Sh 0.66, **HOLD-OUT −1.03** (negativo), anni+ 33%. Gli alt sono
  stati long nel calo 2025-26 e hanno sanguinato — a differenza di TP01 (BTC/ETH) che il
  vol-target+trend portò in cash. I trend degli alt sono più rumorosi/whippy.
 - **corr a TP01 = +0.74** (stessa beta direzionale, come previsto) | corr a XS01 −0.05.
 - **Contributo al portafoglio (TP01 70 + XS 30):** +TREND-52 w20% → FULL −0.01, **HOLD −0.16**;
  w30% → FULL −0.02, **HOLD −0.27**. PEGGIORA.
 ## Lezione
 Broadenizzare il TREND su molti alt NON diversifica: è la **stessa direzionalità** (corr 0.74 con
 TP01) su asset più rumorosi → aggiunge perdita/rumore, non edge. La dimensione trend è già catturata
 in modo pulito da TP01 (BTC/ETH, vol-targeted). L'unica espansione che diversifica davvero resta
 quella **market-neutral** (XS01 cross-sectional), perché è ortogonale alla beta direzionale.
 ## Conclusione (chiusura del filone "espansione universo")
 Esplorate tutte le vie di espansione sui certificati Hyperliquid:
 1. XS su 52-all → diluito (memecoin), negativo.
 2. XS top-liquidità dinamico → peggiore del fisso-19 (liquidità ≠ qualità).
 3. Trend multi-asset su 52 → ridondante (corr 0.74) + hold-out negativo.

 (salta troppo). Scelto **p30** (centro sicuro del plateau, lontano dal cliff p40). Non un knife-edge.
 ## Effetto sul portafoglio (TP01 70% + XS01 30%)
 | XS01 | PORT FULL | PORT HOLD | PORT DD |
 |---|---|---|---|
 | [30] originale | 1.41 | 1.15 | 5.2% |
 | + blend [30,90] | 1.48 | 1.06 | 4.6% |
 | + dispersion gate p30 | **1.55** | **1.55** | **4.4%** |
 XS01 standalone: FULL 1.10→1.50, HOLD 1.03→1.71, DD 14%→10.8%, ~€/g 1.64→2.36. Il gate alza SIA
 FULL SIA hold-out (a differenza del solo blend, che barattava un po' di hold-out).
 ## Meccanismo + caveat onesti
 - **Causale**: soglia = percentile espandente della dispersione PASSATA; nessun look-ahead.
 - **Perche' funziona**: tiene XS attivo nei regimi DISPERSI (2025-26, dove gli alt divergono) e flat
  nei bull compatti (2024). L'hold-out 2025-26 e' ad alta dispersione -> il gate concentra
  l'attivita' di XS proprio li' -> hold-out forte. E' il comportamento voluto, ma NB che il salto
  del hold-out riflette anche che il 2025-26 e' stato un regime ad alta dispersione.
 - Caveat XS01 invariati: storia ~2.5 anni; STAT-MODE (book 19 gambe non eseguibile a 2k).
 ## Azione
 `src/portfolio/sleeves.XS_CFG`: aggiunto `disp_pct=30`; engine `_xsec_returns` gatea su dispersione.
 **Portafoglio attivo: TP01 70% + XS01 (blend [30,90] + gate disp p30) 30% — FULL Sh 1.55 / HOLD 1.55
 / DD 4.4%.** 12 test ok. Affinamenti del SEGNALE (blend + gate) hanno funzionato dove l'espansione
 universo no: i margini su XS sono nella struttura del segnale, non nel numero di asset.

 # 2026-06-19 — Espandere l'universo XS01: PIÙ asset DILUISCONO (i 19 major sono il sweet spot)
 Richiesta: aggiungere altri asset Hyperliquid certificati per rafforzare XS01 (cross-sectional
 momentum). Fatto il lavoro, esito ONESTO: **non rafforza — diluisce.**
 ## Cosa ho fatto
 - Esteso `fetch_hyperliquid.py` a ~54 candidati alt maggiori (mappa Binance auto SYM/USDT, k-prefissi
  esclusi). **52 certificati** (cross-venue 4-11 bps vs Binance, flat 0%, storia 2024+): aggiunti
  ATOM DYDX APE CRV LDO STX GMX SNX BCH COMP WLD UNI TRX FIL RUNE ENA ORDI JUP WIF PYTH FET AR ETC
  ALGO GALA SAND AXS DOT BLUR JTO PENDLE ONDO TAO. Esclusi MKR (delistato HL 2025-09) e FXS
  (migrazione Frax 2026-01) via nuovo gate "ultima barra recente".
 ## Il finding: il cross-section dei 52 è NEGATIVO; i 19 major sono positivi
 Stessa finestra (2024-04 → 2026-06, 807g), mom L*/H10:
 | Universo | k | FULL Sharpe (L30/L60/L90) |
 |---|---|---|
 | **52 asset** | 5 | −0.13 / −0.21 / −0.35 |
 | **52 asset** | 8-12 | tutti negativi (k grande non aiuta) |
 | **19 major** | 5 | +0.30 / +0.36 / **+0.67** (OOS 0.91) |
 I ~33 small/new-cap aggiunti (WIF, JUP, ORDI, PYTH, TAO, GALA, AR, BLUR…) sono idiosincratici/
 mean-reverting: il loro rumore **rovescia** il momentum relativo. Cross-sectional momentum su crypto
 funziona fra i MAJOR liquidi, non sul long tail. Allargare l'universo NON è gratis.
 ## Azione
 - **XS01 resta sui 19 major** (sweet spot già validato: plateau/fee/subset). Lo sleeve
  `_xsec_returns` ora usa una **lista esplicita `XS_UNIVERSE` (19)**, non più glob-all (così
  aggiungere parquet certificati non lo cambia/rompe — avevo inavvertitamente fatto vedere allo
  sleeve 52 asset = negativo).
 - I 52 parquet certificati restano su disco: dato valido per ricerca futura (uno strato diverso —
  es. trend-following multi-asset, o un XS ristretto ai top-liquidità — potrebbe usarli), ma NON XS01.
 - Portafoglio invariato e ripristinato: **TP01 70% + XS01 30%, FULL Sh 1.41 / HOLD 1.15.**
 ## Lezione
 "Più asset = più robusto" è FALSO per il cross-sectional momentum: il long tail di alt piccoli
 diluisce/inverte l'edge. La breadth utile è quella dei major liquidi (corr-strutturata), non il
 numero grezzo.
 ## Tentativo 2: UNIVERSO TOP-LIQUIDITÀ DINAMICO (`xsec_dynuniverse.py`) — anch'esso PEGGIORE
 Provato a selezionare a ogni ribilancio i top-N per dollar-volume 30g (causale) dai 52, poi XS
 momentum fra quelli (adattivo, ragged-aware). Esito:
 | Universo | FULL Sh | OOS25 | anni+ |
 |---|---|---|---|
 | top12 dinamico (L30H10k5) | 0.65 | 0.54 | 67% (2026 −4%) |
 | top15/20/25 dinamico | 0.14-0.38 | ≤0.30 | 33-67% |
 | **fisso-19 major (L30H10k5)** | **0.80** | **1.20** | **100%** |
 | fisso-19 major (L90H10k5) | 0.88 | 0.90 | 100% |
 Contributo: TP01+DYN 70/30 = FULL 1.10 / HOLD 0.60 vs **TP01+XS19 = FULL 1.25 / HOLD 1.15**.
 **Perché fallisce:** la classifica per dollar-volume ammette comunque i MEMECOIN ad alto volume
 (WIF, ORDI, JUP, PEPE...) che hanno volumi enormi ma momentum erratico/mean-reverting →
 diluiscono. **Liquidità ≠ qualità** nelle crypto. I 19 major *curati* (established, corr-strutturati,
 non solo alto volume) restano il sweet spot.
 ## Conclusione
 Né più nomi (52) né top-liquidità dinamico migliorano XS01. **XS01 resta sui 19 major curati**
 (FULL 0.80 / OOS 1.20, 100% anni+). Portafoglio invariato: TP01 70% + XS01 30% (FULL 1.41/HOLD 1.15).
 Per rafforzarlo davvero servirebbe una curatela di QUALITÀ (established majors), che è già ciò che i
 19 sono. Coerente con la disciplina: nessuna espansione senza che migliori il gauntlet. I 52 parquet
 certificati restano per ricerca futura (es. trend multi-asset, dove il long tail non diluisce).

 # Sweep "strategie alternative su Deribit" — 104 ipotesi, 153 agenti (2026-06-20)
 ## Cosa
 Ondata di ricerca onesta richiesta esplicitamente con >=100 agenti: **studiare strategie di
 trading ALTERNATIVE** a TP01/XS01/VRP01 sull'universo certificato Deribit (**BTC/ETH** OHLCV +
 **DVOL**). Catalogo di **104 ipotesi distinte** su 11 famiglie, **un agente-finder per ipotesi**,
 poi **verifica avversariale a 3 scettici** per ogni finding promettente, poi sintesi. Totale
 **153 agenti**, ~5.86M token, ~2h (workflow `scripts/research/alt/wf_altstrat.js`,
 run `wf_0f3659fc-809`).
 Famiglie: BRK (breakout/canali), TRD (trend non-TSMOM), MRV (mean-reversion gated), VOL (DVOL +
 vol realizzata, Deribit-specific), XAS (cross-asset BTC/ETH: ratio/lead-lag/cointegrazione/RS),
 SEA (stagionalità/ora-del-giorno), RSK (overlay difensivi), OPT (strutture opzioni modellate su
 DVOL), MIC (microstruttura/candele), STA (ML walk-forward), CMB (combinazioni/filtri).
 ## Harness condiviso (nuovo, validato)
 `scripts/research/alt/altlib.py` — libreria di valutazione ONESTA e **vettoriale** usata da tutti
 gli agenti, così il no-look-ahead è strutturalmente impossibile:
 - `eval_weights(df, target)`: posizione decisa con dati `<= close[i]`, **tenuta durante la barra
  i+1** (lo shift lo fa la libreria), fee su turnover, **fee-sweep** 0.00–0.30% RT incorporato.
 - `study_weights/study_signals`: ogni ipotesi girata su **entrambi gli asset** + **HOLD-OUT 2025+**
  + per-anno, con verdetto conservativo PASS/WEAK/FAIL (richiede min-asset full>=0.5 **e** hold>=0.2
  **e** sopravvivenza fee).
 - DVOL allineato **causalmente** (`merge_asof` backward), storia dal 2021-03.
 - **Calibrazione:** la replica TSMOM riproduce i numeri noti leak-free di TP01 (BTC full 1.12 /
  hold 0.31, DD 77%→23%); buy&hold correttamente FALLISCE l'hold-out (full 0.79, hold −0.37).
  104 script riproducibili in `scripts/research/alt/runs/`.
 ## Esito — NIENTE di nuovo batte o diversifica lo stack esistente
 Su 104 ipotesi: **16 promettenti**, **1 sola sopravvissuta** alla verifica avversariale (STA05),
 e anch'essa **ridondante/non deployabile**. È il risultato pulito e atteso per un progetto al suo
 **soffitto strutturale BTC/ETH-direzionale ~1.3** (già documentato). Lo stack
 **TP01 (55%) + XS01 (25%) + VRP01 (20%) resta imbattuto** da questa ondata.
 Il segnale ricorrente: decine di trend-follower prendono **FULL Sharpe alto (~1.0–1.3)** ma
 **HOLD-OUT 2025 negativo** (Supertrend, ADX-EMA, Heikin-Ashi, Turtle, SMA200-regime,
 Donchian+Chandelier, Kalman, OBV, body-ratio, ...): è **trend-beta del toro**, non alpha, e si
 rompe nell'hold-out. I PASS apparenti erano quasi tutti **(a)** singola cella fortunata
 sull'hold-out, oppure **(b)** TP01/TSMOM con un overlay attaccato sopra.
 ### L'unico sopravvissuto: STA05 — EWMA-cross ensemble vote (LEAD, non sleeve)
 Voto d'insieme su 13 coppie EMA (fast {5,10,20,40} × slow {40,80,120,200}, fast<slow),
 posizione = voto medio firmato, vol-target 20%/cap 2x, 1d. Verifica: **leak-free** (perturbazione
 barre future = 0), **plateau** di parametri, **non** fortuna di un singolo anno (jackknife
 drop-one-year 0.55–0.96), sopravvive fee a 0.30% RT. Ho rieseguito il **blend test** raccomandato
 (50/50 BTC+ETH, mia stessa griglia di TP01, fee 0.10% RT):
 | variante | FULL Sh | DD | HOLD Sh | corr→TP01 (full/hold) |
 |---|---|---|---|---|
 | TP01 (canonico, controllo) | **+1.30** | 14.3% | +0.31 | — |
 | STA05 long-only | +1.24 | 16.3% | +0.21 | **0.93 / 0.94** → ridondante |
 | STA05 **long-short** | +0.87 | 28.6% | **+0.86** | **0.71 / 0.53** |
 Blend TP01+STA05_LS: `0.75·TP01 + 0.25·LS` → **FULL 1.24, HOLD 0.31→0.59, DD 16.1%**;
 `0.50/0.50` → FULL 1.13, **HOLD 0.75**, DD 18.8%.
 **Lettura onesta (più precisa della sintesi del workflow, che lo aveva liquidato come "dominato
 su ogni asse"):** la versione **long-only** è ridondante con TP01 (corr 0.94). La versione
 **long-short** invece è solo moderatamente correlata (**0.53 nell'hold-out**) e **migliora
 davvero l'hold-out del blend** (0.31→0.59 a peso 25%), al costo di un po' di FULL Sharpe
 (1.30→1.24) e DD (14%→16%). MA: l'hold-out è **solo 536 giorni** (include lo stub 2026 corto) →
 classica trappola "bello OOS ma OOS breve", e standalone ha DD 28.6%. **Verdetto: LEAD da
 monitorare forward, NON deploy, NON sleeve confermato.** Da rivalutare quando l'hold-out cresce.
 ## Famiglie confermate MORTE / ridondanti (negativi onesti)
 - **BRK** breakout (Donchian/Keltner/Bollinger/ORB/NR7/inside-bar): ogni variante rompe l'hold-out
  BTC; l'unico PASS (BRK04) è cella singola overfit con maxDD 63%.
 - **TRD** trend non-TSMOM: tutto trend-beta del toro ridondante con TP01; i 4 PASS (TRD02/07/08/10)
  sono fortuna di singola cella sull'hold-out, dominati dal TSMOM.
 - **MRV** mean-reversion: la crypto **tende, non torna**; molti negativi anche a fee zero, **0 PASS**
  → conferma su dati certi la lezione v2.0.0 ("il fade è artefatto").
 - **VOL** gate/overlay DVOL su TSMOM: ogni overlay (VOL03/04/08/09/11) è **peso morto netto-negativo**;
  la parte robusta è sempre TP01 nudo, la componente DVOL/EWMA aggiunge anti-valore.
 - **XAS** spread BTC/ETH (ratio/lead-lag/cointegrazione/RS/dual-mom): gli spread **tendono non
  revertono** (negativi a fee zero); le "rotazioni" PASS (XAS03/04/09) sono TP01 travestito con
  selezione fortunata sull'hold-out.
 - **SEA** stagionalità: fee-killed a 1h, artefatti di regime a 1d, nessun hold-out cross-asset.
 - **RSK** overlay di rischio (circuit breaker/kill-switch/DD-scaling/inverse-vol RP): o seguono il
  prezzo (buy&hold travestito) o aggiungono frizione senza proteggere dove serve.
 - **MIC** micro-pattern candele: hold-out crolla cross-asset; l'unico "survivor" MIC05 è l'artefatto
  di **un singolo evento** (short del crash 2026-01-29 su ~13 trade).
 - **STA** ML su feature di prezzo (Ridge/Logistic/RF/Kalman/SGD/AR1/k-means): nessun potere
  predittivo OOS; l'unico PASS (STA05) è l'ensemble di trend = TP01.
 - **CMB** combinazioni: ogni combo è TP01 più un filtro che distrugge valore.
 - **OPT** strutture opzioni (modellate su DVOL ATM, niente skew): code severe (ETH maxDD 96% su
  iron condor), **lead-only** al meglio → conferma la regola VRP01 "niente short-vol da modello in
  deploy". Numeri tipo OPT02/OPT04 hold-out 2.4/1.96 sono artefatto del premio modellato + asset
  asimmetrico (ETH fallisce) → giustamente NON promettenti.
 ## Lezioni metodologiche (azionabili)
 1. **L'harness deve premiare lo Sharpe MARGINALE vs un baseline TP01, non lo Sharpe ASSOLUTO.**
   `study_weights` valuta lo Sharpe assoluto: così ogni overlay-su-TSMOM **eredita** lo Sharpe di
   trend di TP01 e prende un PASS fasullo (VOL03/04/08/09/11, CMB04/06). Per la prossima ondata:
   valutare il **contributo incrementale** rispetto a TP01 nudo, così gli overlay non possono
   ereditare un PASS.
 2. **Prima di gradare PASS, esigere (a) un PLATEAU di parametri (non una cella isolata) e (b) un
   jackknife drop-one-month / drop-best-day sull'hold-out.** Questi due check da soli hanno ucciso
   **13 dei 14** falsi positivi in verifica avversariale.
 3. La verifica avversariale a 3 scettici con angoli diversi (leak / overfit-robustezza /
   plausibilità-economica-vs-TP01) ha funzionato: ha distinto i 15 falsi positivi dall'1 robusto.
 ## Raccomandazione
 **Non aggiungere nulla di questa ondata al portafoglio live.** Lo spazio
 **BTC/ETH-direzionale single-asset è esaurito**: ogni PASS era hold-out-fitting o un overlay su TP01.
 Redirigere il budget di ricerca verso **meccanismi davvero diversi** dove il soffitto non morde:
 espandere/monitorare forward **XS01** (cross-sectional sui 51 alt Hyperliquid certificati — l'unico
 che abbia mai battuto il soffitto) e **VRP01 reale** (quando cerbero-bite cattura skew live + uno
 stress). Tenere **STA05_LS** in lista LEAD per il forward-monitor dell'hold-out.
 Artefatti: `scripts/research/alt/altlib.py`, `scripts/research/alt/runs/*.py` (104),
 `scripts/research/alt/wf_altstrat.js`, verifica blend `/tmp/verify_sta05.py`.
 ## Follow-up — MARGINAL SCORER implementato (non più solo raccomandazione)
 La lezione #1 ("valutare lo Sharpe MARGINALE vs baseline TP01, non assoluto") è ora **codice**
 in `altlib.py`:
 - `tp01_baseline_daily()` — TP01 CANONICAL 50/50 BTC+ETH, rendimenti netti giornalieri (cache).
  Riproduce il canonico (full 1.30 / hold 0.31) — bloccato da test.
 - `marginal_vs_tp01(cand_daily)` — corr a TP01 (full/hold), **uplift del blend** (Sharpe di
  TP01+w·cand meno TP01, full & hold-out, w∈{0.25,0.5}), **beta a TP01 + alpha residua** (parte
  ortogonale al trend), e un **verdetto**: ADDS / REDUNDANT / DILUTES / NEUTRAL.
 - `study_marginal(name, target_fn)` — valuta un candidato **sia** in assoluto (`study_weights`)
  **sia** marginale; `earns_slot = (abs_grade != FAIL) AND (marginal_verdict == ADDS)`.
 - Convenzione pulita `target_fn(df, asset)` (via `_call_target`) per le strategie DVOL/cross-asset
  — niente più inferenza-asset hacky (il VOL03 dell'agente la sbagliava, usava DVOL BTC anche per ETH).
 - Demo riproducibile `scripts/research/alt/marginal_demo.py` + test `tests/test_marginal_scorer.py`.
 **Dimostrazione (la prova che il fix discrimina):**
 | candidato | assoluto | marginale | earns_slot |
 |---|---|---|---|
 | TP01-itself (sanity) | WEAK | REDUNDANT (corr 1.0, uplift 0) | False |
 | **STA05 long-short** (il lead) | PASS | **ADDS** (corr-hold 0.53, blend-hold +0.29) | **True** |
 | STA05 long-only | WEAK | REDUNDANT (corr 0.93/0.94) | False |
 | VOL03 DVOL-gated TSMOM (overlay) | WEAK | NEUTRAL (corr 0.93, uplift triviale) | False |
 | **CMB04 momentum+low-vol (overlay)** | **PASS** | **NEUTRAL** (corr 0.94) | False |
 Il punto chiave è l'ultima riga: **CMB04 prendeva un PASS assoluto col vecchio harness, ma il
 marginal scorer lo declassa correttamente** — il suo "Sharpe 1.0" è trend di TP01 ereditato al 94%,
 non alpha nuovo. Regola operativa d'ora in poi: una nuova strategia direzionale BTC/ETH si giudica su
 `study_marginal` (earns_slot), non sullo Sharpe assoluto.
 ## "Resta qualche candidato?" — gate marginale + jackknife su TUTTI i contendenti forti
 Passati i 7 promettenti più forti non-ancora-marginal-testati (`marginal_remaining.py`):
 Vortex/Hull (FAIL nella ricostruzione pulita), VOL11 kill-switch (corr 0.94 → REDUNDANT), XAS03/09
 rotazioni (NEUTRAL, anzi RS-rotation **diluisce** l'hold-out −0.20), **TRD07 KAMA** e **VOL08**
 (entrambi marginale=ADDS). Ma il marginal-point-estimate **può essere ingannato da un singolo mese**:
 ho aggiunto al gate il **jackknife OOS** (`robust_oos` = uplift positivo nell'anno OOS pulito 2025
 **e** sopravvive al drop-best-month). Risultato:
 | candidato | clean-2025 uplift | drop-best-month | robust_oos | earns_slot |
 |---|---|---|---|---|
 | TRD07 KAMA | +0.089 | **−0.034** | False | **False** (era ADDS!) |
 | VOL08 RV-term | +0.158 | +0.034 | True | **True** |
 | STA05 long-short | +0.039 | +0.131 | True | True (ma 2025 ~0, il grosso è lo stub 2026) |
 **KAMA è il falso-positivo istruttivo:** ingannava il marginal scorer (uplift +0.056) ma muore al
 jackknife (−0.034 togliendo il mese migliore) → il gate rinforzato (`earns_slot` ora esige
 `robust_oos`) lo uccide correttamente. Codificata così la lezione #2 in `marginal_vs_tp01`.
 ### Verdetto finale: NESSUN candidato deployabile
 Dopo il gate più severo (abs≠FAIL + marginale=ADDS + jackknife OOS), i 104 collassano a **2 LEAD
 fragili**: **VOL08** (overlay term-structure di vol realizzata) e **STA05_LS** (ensemble EMA
 long-short). Entrambi sono **famiglia-trend su BTC/ETH** (non un meccanismo nuovo), moderatamente
 correlati a TP01 (0.53–0.61 hold-out), con uplift piccolo e concentrato su un OOS di ~1.5 anni →
 **forward-monitor, NON sleeve.** E sono correlati tra loro (entrambi trend) → di fatto **un solo
 tema**: "una costruzione di trend-timing alternativa, modestamente decorrelata a TP01 nel 2025-26".
 La diversificazione vera resta fuori dallo spazio direzionale single-asset (→ XS01 / opzioni reali).

 # 2026-06-20 — Correzione estrazione cerbero MCP: il backfill sintetico (vol=0) ingannava la certificazione
 ## Contesto
 Richiesta: "analizza cerbero MCP correggendo l'estrazione dati storici secondo le analisi fatte".
 Le analisi del progetto avevano già fissato un principio — *"storia nativa Hyperliquid solo dal 2024,
 pre-2024 = backfill, volume 0"* — e `fetch_hyperliquid.py` lo gestiva con un floor `START=2024-01-01`.
 **Il floor non basta.**
 ## Il difetto
 `fetch_hl` chiedeva a cerbero MCP `get_historical` dal 2024-01-01 e certificava ogni asset con tre
 gate: **flat-bar** (O==H==L==C), **cross-venue** (mediana |close − Binance| < 60 bps), **recency**.
 Nessuno guardava il **volume**. Risultato: gli asset listati su HL *dopo* lo START passavano come
 PULITO pur essendo in gran parte **backfill sintetico**.
 Ispezione del volume sui parquet (leading run di barre a volume 0):
 | asset | barre | leading vol=0 | primo trade reale | % sintetico |
 |---|---|---|---|---|
 | **AXS** | 902 | **748** | 2026-01-18 | **82.9%** |
 | ALGO | 902 | 338 | 2024-12-04 | 37.5% |
 | SAND | 902 | 338 | 2024-12-04 | 37.5% |
 | AR | 902 | 58 | 2024-02-28 | 6.4% |
 | ETC | 902 | 11 | 2024-01-12 | 1.2% |
 | BTC/ETH + 19 major | 902 | 0 | 2024-01-01 | 0% |
 AXS era **certificato PULITO** (flat 0%, cross-venue 9.5 bps) pur avendo solo ~5 mesi di trading reale.
 ## Verifica diretta su cerbero MCP (token mainnet)
 Interrogato l'endpoint `cerbero-mcp.tielogic.xyz/mcp/tools/get_historical` (bot-tag
 `pythagoras-mainnet`):
 - **BTC**: 902 barre, leading vol=0 = 0, volume reale dal 2024-01-01 (V=699, 2437, 5306…). Nativo. ✓
 - **AXS**: 902 barre, **748 leading vol=0**, primo vol>0 = 2026-01-18. Le barre a volume 0 hanno
  prezzi (O/H/L/C) che **coincidono con Binance**:
  | data | cerbero close | binance close | Δ |
  |---|---|---|---|
  | 2024-01-01 | 9.262 | 9.26 | 2.2 bps |
  | 2024-01-02 | 8.949 | 8.94 | 10.1 bps |
  | 2024-01-03 | 7.937 | 7.95 | 16.4 bps |
 **Diagnosi provata:** cerbero MCP riempie il periodo pre-quotazione con barre **sintetiche — volume 0,
 prezzi copiati da un venue di riferimento (Binance)**. Per questo i vecchi gate venivano ingannati:
 - cross-venue passa → i prezzi *sono* Binance (Δ 1–16 bps);
 - flat passa → le barre non sono flat (hanno movimento di prezzo);
 - ma **volume 0** → su HL quelle candele **non erano negoziabili**. È esattamente il caso v2.0.0
  (edge su un book che non c'era).
 ## Correzione (`scripts/analysis/fetch_hyperliquid.py`)
 1. **Il VOLUME è il rivelatore del backfill** → `trim_backfill()` taglia il run iniziale di barre a
   volume 0; si tiene solo la **serie nativa**.
 2. **Gate storia nativa** `MIN_NATIVE_DAYS=365`: dopo il taglio serve ≥ 1 anno di vita reale →
   scarta chi è troppo corto (AXS, 154 barre reali → fuori).
 3. **Gate vol=0 interno** `INTERIOR_VOL0_MAX=5%`: gap di liquidità oltre il taglio iniziale.
 4. **cross-venue/flat ricalcolati SOLO sulle barre reali** (non più sui sintetici).
 5. **I parquet degli asset scartati vengono rimossi** (disco == set certificato; niente file
   contaminati a riposo).
 ## Risultato
 - Universo certificato: **52 → 51** (AXS scartato).
 - ALGO/SAND (−338 barre), AR (−58), ETC (−11) ripuliti dal backfill → ora start reale corretto.
 - **I 19 major di XS01 hanno 0 backfill → invariati**: la strategia live (`XS_UNIVERSE` esplicito) NON
  è toccata. Verificato: portafoglio 3-way (TP01+XS01+VRP01) gira identico, FULL Sh 1.68 / HOLD 1.67.
 - Re-fetch end-to-end su cerbero reale: 51 PULITO, sweep su tutti i file → 0 backfill residuo.
 ## Nota su una conclusione precedente
 Il diario `2026-06-19-xsec-universe-expansion.md` concludeva "cross-section dei 52 = negativo". Quella
 finestra includeva i sintetici (AXS 83%, ALGO/SAND 37% di barre vol=0 con ritorni non eseguibili): la
 magnitudine del risultato era **in parte un artefatto**. La conclusione qualitativa (il long-tail
 diluisce XS01; i 19 major sono il sweet spot) resta valida, ma il numero netto è 51 e il test andrebbe
 ri-girato sui dati puliti se si volesse riusare quell'universo.
 ## Lezione
 `flat` + cross-venue **non bastano** a certificare un feed che fa backfill copiando un altro venue: il
 backfill è plausibile sui prezzi proprio perché è copiato. Il **volume** (=liquidità reale) è il gate
 che mancava. Coerente con la regola di prim'ordine v2.0.0: certificare il dato — anche il *volume*,
 non solo il prezzo — prima della strategia.

 # 2026-06-20 — Analisi strategie FinanceOld + VRP v2 (defined-risk + gate IV-rank)
 ## Contesto
 Richiesta: analizzare le strategie in `../FinanceOld`, provare a migliorarle, testarle su dati storici.
 Quattro progetti esaminati. Verdetto di **backtestabilità onesta** sui dati certificati (BTC/ETH
 Deribit mainnet + DVOL):
 | Progetto | Strategia | Backtestabile sui dati certi? |
 |---|---|---|
 | **FundingRateArbitrage** | Spread funding cross-exchange (perp-perp, spot-hedge) | ❌ Nessun dato funding storico nel repo (solo `exchange_settings.json`). Edge = differenza cross-venue, non ricostruibile. |
 | **Polybot** | Latency-arb Polymarket (BS digital-option) + sure-bet delta-neutral | ❌ `dataVPS/collector.db` (645MB) ha solo **~3 giorni** di `poly_books`+`funding`, e la tabella `ticks` (prezzi perp = cuore dell'edge) è **corrotta** ("database disk image is malformed"). L'edge è la latenza: non riproducibile su barre OHLC comunque. |
 | **OptionSpalping** (→Cerbero) | LLM autonomo su opzioni Deribit + perp Hyperliquid | ⚠️ È un agente LLM, non una regola meccanica. Il *concetto* (income short-vol su Deribit) è testabile. |
 | **OptionsAgent** | **Bear Call Spread + Long VIX hedge** su IWM, con 5 gate d'ingresso | ✅ Il *concetto* (vendi premio rischio-definito, incassa VRP, gate su IV-rank/regime) mappa direttamente sul nostro `options_vrp_lab.py`. |
 → Scelta operatore: **focus VRP opzioni**. L'unico filone con dati veri + metodologia onesta.
 ## Baseline (options_vrp_lab.py, ora con fee)
 Vendita put NUDA settimanale delta -0.28, premio BS su DVOL reale. f = premio_reale/modellato.
 - `f=1.0` (conservativo): **FULL Sh 0.78, DD 33%, worst-week -16.6%, HOLD-OUT Sh -0.25** → muore OOS.
 - Il rischio è la **CODA**: worst-week su LUNA (2022-06), crash 2021-05. Anno 2022 = -9%.
 ## VRP v2 — 3 idee di OptionsAgent portate nel framework
 Nuovo script `scripts/research/options_vrp_v2.py`. Tutto **causale** (strike/premio/gate da dati
 ≤ sell-date; payoff a scadenza sui prezzi certificati). Fee opzioni Deribit modellate (12.5% del
 premio netto per round-trip = cap del fee reale). Capitale = strike corto (cash-secured) per
 entrambe le strutture → DD/worst comparabili.
 1. **Rischio definito (PUT CREDIT SPREAD)** — vendi put -0.28, COMPRI put -0.10. Il long wing
   **cappa la coda per costruzione**: worst-week -16.6% → **-7.4%**, DD 33% → 21%, Sh 0.78 → 0.99.
 2. **Gate IV-RANK > 0.30** (cond. d'ingresso di OptionsAgent) — vendi vol solo quando ricca
   (percentile espandente causale di DVOL). Trada il **58%** delle settimane → **Sh 1.35** e
   ribalta **HOLD-OUT da -0.25 a +0.28**. È l'alpha vero: il filtro di regime, non la struttura.
 3. **Crash-skip IV-rank > 0.90** (NO-GO, come "VIX>35" di OptionsAgent) — marginale da solo.
 4. **Gate VRP>0** (DVOL>RV30 causale) — marginale (il VRP è >0 il 78% del tempo, poco selettivo).
 ### Risultati chiave (book 50/50 BTC+ETH, f=1.0 conservativo)
 | Config | FULL Sh | DD | worst-wk | HOLD-OUT Sh | attivo |
 |---|---|---|---|---|---|
 | naked (baseline) | 0.78 | 33% | -16.6% | **-0.25** | 100% |
 | spread | 0.99 | 21% | -7.4% | -0.26 | 100% |
 | spread + ivr30 | **1.35** | 14% | -7.4% | **+0.28** | 58% |
 | **COMBO** (spread+vrp+ivr30+crashskip) | 1.10 | 12% | -7.4% | **+0.60** | 41% |
 COMBO f=1.0 per-anno: 2021 +26%, 2022 **-6%**, 2023 +2%, 2024 +18%, 2025 -0%, 2026 +5%
 (il 2022, anno-crash che dimezzava il nudo, è quasi piatto: la coda è tagliata).
 A `f=1.29` (skew reale misurato in regime calmo) la COMBO fa FULL Sh 1.87 / HOLD 1.45 / DD 9%.
 ### Contributo al portafoglio (COMBO f=1.0 vs TP01)
 - Corr settimanale **+0.07** (scorrelato, come il VRP nudo).
 - TP01 70% + OPT 30% → Sh **1.00** (TP01 solo 0.73), DD **7%**.
 - TP01 50% + OPT 50% → Sh **1.19**, DD 7%.
 ## Conclusione onesta
 Le idee di OptionsAgent **migliorano davvero** lo sleeve VRP, in modo OOS-robusto:
 - la **struttura defined-risk** taglia la coda (worst -16.6%→-7.4%, DD -19pt) → meno dipendenza dal
  f di stress, che era il rischio non catturato del lead nudo;
 - il **gate IV-rank** è l'alpha: ribalta l'HOLD-OUT da negativo a positivo vendendo solo vol ricca.
 Resta un **lead, non un deploy**: premio MODELLATO su DVOL ATM (skew non esplicito), book a 1d, e
 serve la catena reale (cerbero-bite) per il f di stress in un crash. Ma è un miglioramento netto,
 quantificato e onesto, del miglior lead income che avevamo. Prossimo passo: rivalutare il f di stress
 quando cerbero-bite cattura un crash, e validare lo skew reale sul long wing (-0.10).
 Script: `scripts/research/options_vrp_v2.py`. Baseline: `scripts/research/options_vrp_lab.py`.
 ## Integrazione come sleeve (VRP01)
 La COMBO è stata integrata nel portafoglio come **VRP01** (`src/portfolio/sleeves._vrp_combo_returns`,
 `vrp_sleeve()`). Implementazione self-contained in `src/` (niente import da `scripts/`): pricing BS +
 strike-from-delta + gate causali inline, DVOL da `data/raw/dvol_*.parquet`.
 **Settimanale → giornaliero (onesto):** il rendimento settimanale è piazzato sul **giorno di
 scadenza**, 0.0 sugli altri giorni dello span. Questo PRESERVA lo Sharpe annualizzato (niente
 smoothing che gonfierebbe il daily Sharpe) e tiene lo sleeve presente ogni giorno → peso costante
 nell'outer-join del portafoglio. Verificato: lo sleeve daily replica i numeri settimanali
 (FULL Sh 1.09, HOLD 0.60, DD 12%), corr daily vs TP01 = +0.01.
 **Pesi (per evidenza, engine reale):** TP01+VRP01 monotòno fino al 40% VRP (FULL 1.30→1.55,
 HOLD 0.31→0.52, DD fermo 14%). Essendo VRP un lead MODELLATO (non deploy pieno), non lo sovrappeso:
 registry = **TP01 0.55 / XS01 0.25 / VRP01 0.20** (TP01 resta maggioranza, l'unico deployable pieno).
 La validazione 3-way completa richiede i dati Hyperliquid (XS01, gitignored, token Cerbero) → gira
 locale con `scripts/portfolio/run_portfolio.py`.
 Test: `tests/test_vrp_sleeve.py` (5 pass: monotonìa BS, ordering strike, determinismo+griglia
 giornaliera, gate riducono l'attività, coda tagliata <-15%).

 """FETCH + CERTIFY universo Hyperliquid (Cerbero MCP MAINNET) — espansione cross-sectional.
 Hyperliquid (via cerbero-mcp mainnet) offre ~230 perp liquidi, ma storia nativa REALE solo dal
 2024 (pre-2024 = backfill, volume 0). Qui scarico un set liquido a 1d (2024+), e CERTIFICO ogni
 asset come BTC/ETH: cross-venue vs Binance (realismo) + flat-bar + VOLUME (liquidita'). Scrivo SOLO
 i puliti in data/raw/hl_<sym>_1d.parquet (namespace dedicato, NON mischiato col Deribit BTC/ETH).
 Disciplina: Cerbero ci ha gia' bruciato (testnet) -> niente fiducia, solo certificazione.
 CORREZIONE estrazione (2026-06-20, "analisi fatte"): il floor START=2024-01-01 NON basta. Cerbero
 restituisce BACKFILL SINTETICO (volume==0, ma prezzi copiati da un venue di riferimento -> matchano
 Binance e NON sono flat) per il periodo PRIMA che l'asset quotasse davvero su Hyperliquid. Cosi'
 asset listati a meta'/fine 2024+ passavano cross-venue+flat ed erano certificati PULITO pur essendo
 in gran parte sintetici (es. AXS 83% backfill: trading reale solo da 2026-01; ALGO/SAND 37%). E' lo
 stesso errore v2.0.0 (edge su un book che non c'era). Fix: (1) il VOLUME e' il rivelatore di backfill
 -> si TAGLIA il run iniziale di barre a volume 0 e si tiene solo la serie NATIVA; (2) gate su storia
 nativa minima (>= MIN_NATIVE_DAYS reali) -> scarta chi e' troppo corto dopo il taglio; (3) gate su
 volume-0 INTERNO (gap di liquidita') oltre il taglio iniziale; (4) cross-venue/flat ricalcolati SOLO

 """HARNESS DI RICERCA ONESTO — BTC/ETH, v2.0.0 (Fase 0).
 Dopo che l'intera libreria precedente si è rivelata artefatto di feed/harness disonesti,
 la prima cosa di cui fidarsi NON è una strategia ma il banco di prova. Questo modulo è
 quel banco: causale per costruzione, netto fee, con baseline e null model.
 MODELLO CANONICO = SERIE DI POSIZIONE.
  Una strategia è una funzione  signal(df, **params) -> pd.Series/np.array  che dà la
  posizione target per barra in [-1, +1]. REGOLA: position[i] è decisa con dati FINO a
  close[i] (mai oltre) e GUADAGNA il rendimento close[i] -> close[i+1]. L'engine moltiplica
  position[i] * fwd[i] (fwd strettamente futuro rispetto alla decisione) -> niente look-ahead
  per costruzione, e niente fill sull'estremo di candela (si entra al close). La fee è
  addebitata sul TURNOVER |Δposition| (un round-trip 0->1->0 = 2 unità = fee_rt intera).
 GATE (vedi CLAUDE.md): ingresso eseguibile (qui per costruzione), netto fee 0.10% RT,
 OOS held-out, robustezza su griglia, onestà statistica (null model + buy&hold), walk-forward
 per i modelli fittati, liquidità (BTC/ETH ok).

 paper trading FORWARD-ONLY su capitale virtuale (default 2000 USDT), portafoglio 50/50
 BTC+ETH a 1d. Stato persistente -> resume al riavvio.
 DESIGN (onesto, niente esecuzione reale: l'esecuzione e' DISABILITATA nel progetto):
  - Legge i parquet certificati locali (data/raw, BTC/ETH 1h) e resampla a 1d.
  - Alla prima esecuzione parte dall'ultima barra 1d CHIUSA disponibile (forward-only:
    NON include lo storico nel PnL di paper, traccia solo da ora in avanti).
  - Ad ogni run processa le NUOVE barre 1d chiuse dall'ultima volta: applica il rendimento
    della posizione tenuta, addebita le fee sul turnover, registra i trade sui cambi di
    posizione, poi ricalcola la posizione-bersaglio (decisa con dati <= ultima barra chiusa).
  - Per avere barre fresche, aggiornare prima i dati:

 """altlib — SHARED HONEST EVALUATION LIBRARY for the alt-strategy fan-out (2026-06-20).
 Built for the "studia altre strategie alternative su Deribit" research wave: >=100 agents,
 each studying ONE distinct strategy hypothesis on the certified BTC/ETH (+ DVOL) universe.
 Every agent imports THIS module so that:
  * NO look-ahead is structurally possible: a target/weight decided at close[i] is held
    during bar i+1 (the evaluator shifts it for you — you never multiply by r[i] with a
    weight that used close[i] for the *same* bar).
  * Fees are realistic Deribit (0.10% RT taker = 0.0005/side) and a fee SWEEP is built in.
  * Metrics are comparable: FULL Sharpe/CAGR/maxDD, HOLD-OUT (2025-01-01+), per-year.
  * Only certified data exists (BTC/ETH from Deribit mainnet, DVOL from Deribit). load()
    raises on anything else — a physical guardrail.
 Two evaluation styles:
  1. eval_weights(df, target)  -> for CONTINUOUS-position strategies (trend, vol overlays,
     pairs, risk-parity). `target` is a per-bar position (fraction of equity, sign=dir),
     decided with data <= close[i]. VECTORIZED (numpy) -> fast even on 68k 1h bars.
  2. eval_signals(df, entries) -> for DISCRETE entry/exit strategies (breakout w/ TP-SL,
     mean-reversion bounce). Wraps the project's trade-based harness. Use on 1h/1d only
     (the Python loop is O(n*max_bars); 5m has 840k bars -> too slow on 2 CPUs).
 Quick start (inside an agent script):
    import sys; sys.path.insert(0, "/opt/docker/PythagorasGoal/scripts/research/alt")
    import altlib as al
    rep = al.study_weights("MY-STRAT", lambda df: my_target(df), tfs=("1d","12h"))
    print(al.fmt(rep)); print(al.as_json(rep))   # human + machine

 # MARGINAL SCORING vs TP01 baseline — the lesson of the 2026-06-20 sweep.

 # Absolute Sharpe is NOT enough to earn a portfolio slot: an overlay on TSMOM
 # (DVOL gate, low-vol filter, kill-switch, ...) inherits TP01's trend Sharpe and
 # scores ~1.0-1.3 while adding ZERO new return. The only question that matters for
 # a NEW sleeve is: does it IMPROVE the existing TP01 portfolio out-of-sample?
 # We answer it three ways: (a) blend uplift (Sharpe of TP01 + w*candidate minus

 # removing the TP01 beta (the part of the candidate orthogonal to trend).

 """BRK02 — Donchian55 + Chandelier ATR trailing stop.
 IDEA:
  - Enter LONG when close[i] breaks above the 55-bar Donchian high (prior bars, causal).
  - Exit (go flat) when close[i] falls below the Chandelier trailing stop:
      chandelier_stop = highest_close(22 bars, ending at i) - 3 * ATR(22, ending at i).
  - Position is 0 (flat) or 1 (long). No short. Vol-targeted to 20% with 2x cap.
 Implementation (weights style, continuous position):
  - Donchian high computed on PRIOR bars (shift(1) already done by al.donchian).
  - Chandelier stop computed causally on current+prior bars:

    exit indicator. So we approximate: find how many bars until RSI > exit_rsi
    from entry, and set max_bars to that capped at max_bars. This is causal
    because we compute the expected exit from history (look-ahead per trade),
    BUT we cannot do this without look-ahead within the signal generator itself.
    HONEST APPROACH: Use max_bars only as exit. The harness will hold for up to
    max_bars. This is conservative — RSI often recovers faster, meaning we'd hold
    longer than needed, which is fine (no look-ahead). Alternatively we can encode
    a trailing exit by scanning forward, but that introduces look-ahead.
    CORRECT NO-LOOK-AHEAD APPROACH:
    Compute signal at bar i. Set max_bars = max_bars. The exit is "held max_bars
    or until harness closes." Since the harness only supports TP/SL/max_bars,
    we use max_bars. This is honest.
    No TP, no SL, exit by time (max_bars) — straightforward.

 """CMB03 — Multi-TF trend confirm (4h fast + 1d slow agreement).
 HYPOTHESIS: On the 4h TF, go long only when the 1d trend (TSMOM or SMA50)
 agrees (is bullish). The intuition is that a fast-TF TSMOM signal might have
 more noise; filtering by the slow TF trend reduces false signals.
 CAUSAL ALIGNMENT (critical - see obs 4866):
  - 1d bar at timestamp T closes at end of day T. The 4h bar that CLOSES at
    the same time or later (within day T+1 onwards) can use it causally.
  - We compute the 1d signal on the 1d dataframe, then merge_asof onto 4h
    using the 1d bar CLOSE timestamp -> the 4h bar is valid only AFTER the
    1d bar has fully closed (direction="forward" with offset to avoid using
    the still-open 1d bar).
  - Implementation: for each 1d bar at timestamp T_close, the signal becomes
    available at T_close (the bar just closed). We map it to 4h bars whose
    open timestamp >= T_close (i.e. the NEXT 4h bar after the 1d bar closed).
    This means we use pandas merge_asof with left=4h open timestamps and
    right=1d close timestamps, direction="backward" — the 4h bar at open T
    gets the most recent 1d signal where 1d_close <= 4h_open.

 """CMB06 — Trend + Seasonality Combo
 IDEA: TSMOM long-flat (multi-horizon, vol-targeted, like TP01) but scale the
 exposure UP in historically strong calendar windows (day-of-week + month-of-year
 expanding expanding expectancy). Causal only: expectancy estimated on expanding window
 using data BEFORE the current bar.
 Design:
 - Base signal: TSMOM multi-horizon (1M / 3M / 6M), long-flat, vote-then-sign
 - Volatility targeting: 20% target, 2x lev cap (same as TP01)
 - Seasonality multiplier: expand-window daily/monthly return expectancy,
  normalised to [scale_min, scale_max] so it's a scalar boost, not a flip.
  The multiplier is always >= 0 (never inverts the trend).
 Causal guarantee:
 - Day-of-week expectancy at bar i uses only past bars (strict shift: computed on
  data up to bar i-1, applied at bar i).
 - Month-of-year same.
 - Both use EXPANDING window (not rolling) -> no future-data leak, and it
  gradually stabilises as history accumulates.

 flat (or short) when IBS > high_thresh (closed near high = overbought).
 Classic daily mean-reversion edge. Testing on certified BTC/ETH daily bars.
 Variants tested:
  V1: Long-flat  thresholds 0.20/0.80 (classic textbook)
  V2: Long-flat  thresholds 0.25/0.75 (slightly wider)
  V3: Long-short thresholds 0.20/0.80 (adds short leg)
  V4: Long-flat  thresholds 0.15/0.85 (tighter = rarer signals)
  Best variant selected by min-asset hold-out Sharpe.
 All positions are vol-targeted (20% annualized, 2× leverage cap).
 Evaluated on 1d timeframe (IBS is a daily signal by design).

 on Deribit 1d resampled bars (max gap found = 0.089%). True overnight gaps don't exist.
 ADAPTED INTERPRETATION: "Gap" operationalized as a large down day:
  - Bar i closes gap_thresh% below prior close (big intraday decline)
  - Enter LONG at close[i], TP = close[i-1] (full reversion), SL below
  - This captures the "gap fill" spirit: buy after a large daily drop expecting recovery

 """OPT01 — Covered-Call Overlay
 IDEA: Long spot + sell weekly OTM call modeled via Black-Scholes using DVOL as IV.
 Net return = spot return capped at strike + call premium received.
 This is a MODELED lead — real execution requires options book.
 Methodology:
 - Hold 1 unit of spot BTC/ETH.
 - Each week sell 1 weekly call at strike = S * exp(delta_otm * sigma * sqrt(T)).
  delta_otm controls how far OTM (e.g. 0.10 = 10% OTM in log space).
 - Premium modeled via Black-Scholes (causal DVOL as IV).
 - Net weekly return = min(spot_return, log(K/S)) + premium/S
  i.e. spot gain is capped at the call strike, but we always keep the premium.
 - Study 4 param sets: delta_otm in {0.05, 0.10} x weekly/biweekly rebalance.
 - CAVEAT: premiums are MODELED on DVOL ATM/skew not accounted for -> lead-only.
 - DVOL history starts 2021-03 -> backtest from 2021-03 only.
 Style: study_weights (continuous position ~1x long + overlay).

        # REVISED CLEAN APPROACH: compute per-bar net returns and pass them as position=1

        # Actually the cleanest approach for a covered call is:
        # - It's ALWAYS long spot (position=1), but at option expiry we adjust for:
        #   (a) cap at strike -> subtract excess gain if S>K
        #   (b) add premium received
        #
        # For eval_weights, we need to express everything as a "multiplier on the next bar's return".
        # This doesn't work cleanly for multi-bar option cycles.
        #
        # FINAL APPROACH: Express as a WEEKLY bar (resample to weekly), compute one-period CC return.
        # But we're called with a specific tf. Instead, downsample conceptually.
        #
        # We'll return the daily adjustments:
        # On settlement days: position that captures capped gain + premium
        # On non-settlement days: position = 1 (pure spot)
        #
        # To avoid the eval_weights shift making things off-by-one, we set:
        # target[i] = position to hold during bar i+1
        # On bar i+1 (settlement): net = target[i] * r_spot[i+1]
        # target[i] = cycle_net[i+1] / r_spot[i+1] when r_spot[i+1] != 0
        # Otherwise target[i] = 1 (spot)
        #
        # This is complex. Let's use a clean but simpler approximation:
        # Express covered-call as: spot return + short call option return
        # Short call return on expiry bar = premium_received - max(0, S_end - K)
        # On non-expiry bars: return from short call = 0 (European option, no early exercise)
        #
        # We can decompose:
        # cc_return[i] = spot_return[i] + option_adjustment[i]
        # where option_adjustment[i] is nonzero only on settlement bars.
        #
        # We pass target=1 (always long spot) but we need to add the option overlay separately.
        # eval_weights doesn't support additive adjustments directly.
        #
        # SIMPLEST HONEST IMPLEMENTATION: run a separate loop and return the synthetic
        # "effective position" = cc_net_return_for_cycle / spot_return_for_cycle
