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. Suite: 32 verde. Diario: docs/diary/2026-06-20-alt-strategies-100agent-sweep.md Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

 Prima ondata di ricerca onesta su BTC/ETH certificati (5 track, harness condiviso

- **VINCITRICE (l'unica robusta e profittevole): TP01 Trend Portfolio** —
-  `src/strategies/trend_portfolio.py`. TSMOM multi-orizzonte (1-3-6 mesi) vol-targeted,

-  **CAGR ~16.6%, Sharpe ~1.32-1.36, maxDD ~12-14%, positiva ogni anno 2019-2026**.
-  Robusta su tutti i TF (15m-1d), regge fee fino a 0.40% RT, su entrambi gli asset.
-  Paper trader: `scripts/live/paper_trend.py`. Test: `tests/test_trend_portfolio.py`.
- **Edge deboli ma reali** (NON standalone, NON migliorano il portafoglio): ML walk-forward
-  su BTC (Sharpe ~0.57), trend 1h long-short (Sharpe ~1.0), relative-value market-neutral
-  ETH/BTC (scorrelato ~0.05 ma Sharpe solo 0.27 → troppo debole per alzare lo Sharpe).
- **MORTO/confermato artefatto:** mean-reversion / fade (negativo anche a fee zero su dati

- **Soffitto strutturale:** con i soli BTC/ETH lo Sharpe di portafoglio si ferma a **~1.3**.
-  Combinare TF o aggiungere la RV non aiuta (ridondanza/edge troppo debole).

+  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).

+  (~−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).

+  TP01+XS01 combinato **FULL Sharpe 1.55, HOLD-OUT 1.55, DD 4.4%**. Aggiunto **VRP01** (options

+  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`.

+- **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.

+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`,

+
+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,

+## Integrazione
+- `src/portfolio/portfolio.py`: combine OUTER-join + rinormalizzazione pesi per-giorno (sleeve a date

+- **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

+  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).

+
+## 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).

+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 |

+| 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

+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

+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.
+

+# 2026-06-19 — Ricerca v2.0.0: Fase 3, conferma avversariale del candidato trend
+
+Candidato: **trend-following long-only (MA-cross)**, l'unico a passare i gate base in Fase 2.
+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.

+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

+
+Segnalazione utente/agente: un look-ahead **ffill MIXED-TIMEFRAME su barre open-labeled**
+(`resample(label="left")`) gonfiava il 4h a Sharpe ~1.60; il risultato reale è ~1.1.
+Conclusione: **NON scendere sotto le 12h** — costi e overfitting dominano.

+- **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

+- **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"`):

+  Il calcolo per-singolo-TF a barre discrete (posizione +1) è sicuro; il guard prefix-recompute lo prova.

+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

+
+**(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.

+(tutti gli asset insieme) e' rumore. Gate: entra solo se la dispersione cross-section del momentum
+supera il percentile ESPANDENTE causale `disp_pct`; altrimenti flat. Sul blend [30,90] dei 19 major.

+- **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.

+# 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

+  (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):

+| 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).

+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

+"""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).

+"""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"))

+# 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
+# TP01 alone, full & hold-out), (b) correlation to TP01, (c) residual alpha after
+# removing the TP01 beta (the part of the candidate orthogonal to trend).

+  but study_signals runs BTC+ETH per config automatically. We pick best.

+"""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

+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

+"""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).

+        # net_returns. Instead, we build a "position" that approximates CC behavior.

+        # REVISED CLEAN APPROACH: compute per-bar net returns and pass them as position=1
+        # with pre-computed net returns embedded via a trick: we set target[i] such that
+        # target[i] * r_spot[i+1] ≈ CC_net_return[i+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.

+"""OPT02 — Cash-Secured Put Wheel Strategy (modeled, lead-only).
+
+HYPOTHESIS: Sell weekly ~0.25-delta put (BS premium from DVOL). If assigned
+(close < strike at expiry), hold spot then sell covered calls. Model assignment
+via close vs strike. Wheel cycle: CSP -> if assigned, sell CC until called away
+-> repeat. DVOL starts 2021-03, so history is shorter.
+
+Style: study_weights (continuous fractional position representing the theta income
+stream, scaled by vol target for risk management).
+
+Implementation:
+- At each weekly decision bar: if NOT in spot (wheel in CSP phase), sell put @
+  ~0.25 delta; if IN spot (wheel in CC phase), sell call @ ~0.25 delta.
+- Assignment check: put assigned if close_expiry < strike_put; call "called away"
+  if close_expiry > strike_call (sell the spot, back to CSP phase).
+- P&L: (premium incasssed - intrinsic payoff) / collateral.
+- Modeled on DVOL ATM (no skew). Premiums scaled by calibration f.
+- Gate: IV-rank > 0.25 (sell vol only when rich, causally computed expanding percentile).
+- Small grid: (delta_put, gate_ivr) -> 4 configs -> report best via altlib.
+
+CAVEAT: modeled, lead-only. No skew, no early assignment, no liquidity filter.

+"""OPT03 — Calendar Spread (DVOL term proxy).
+
+IDEA: A calendar spread (sell short-dated, buy long-dated option) profits when:
+- Term structure is in contango (short vol < long vol) -> theta decay favors the short leg
+- The vol term slope is MEAN-REVERTING: extreme backwardation -> enter long calendar
+
+MODELED APPROACH (since we lack real term surface):
+  - Short-dated vol proxy: EMA(DVOL, span_short) — reacts quickly to spot moves
+  - Long-dated vol proxy: EMA(DVOL, span_long)  — slower, represents long-term expectation
+  - Term slope = short_proxy - long_proxy (positive = backwardation, negative = contango)
+  - Position: go long calendar when slope is high (extreme backwardation -> mean-revert to flat)
+              go short calendar when slope is very negative (extreme contango -> normalize)
+
+  Signal: zscore of (short_ema - long_ema) over rolling window.
+  Direction: mean-reversion -> go LONG when z is high (backwardation = short vol elevated)
+             because short vol will eventually fall back to long vol.
+
+  Vol-target the position (20%, cap 2x).

+"""OPT05 — Delta-Hedged Short Straddle (Variance Premium Harvest)
+
+IDEA: Sell ATM straddle every N days, delta-hedge daily with ACTUAL price moves.
+Net P&L = IV-RV spread (the variance risk premium).
+
+HONEST APPROACH — Direct P&L Simulation (avoids BS gamma approximation errors):
+  1. At roll date i0: sell ATM straddle. Receive premium P = 2*BSCall(S0,S0,T,IV).
+  2. Compute initial delta hedge: delta_straddle = delta_call + delta_put = N(d1) - N(-d1) ≈ 0 ATM.
+     Set delta_hedge_position h0 = -delta_straddle ≈ 0 at initiation.
+  3. Each subsequent bar k: compute new delta at current S_k, T_remaining.
+     Rebalance: dh = new_delta - old_delta. Hedge cost includes:
+       (a) Slippage/market-impact on spot hedge: dh * S_k * fee_hedge (spot fee per side)
+       (b) The actual mark-to-market P&L of the short straddle:
+           delta_PnL = -(C(S_k, K, T_k) + P(S_k, K, T_k) - C(S_{k-1}, K, T_{k-1}) - P(S_{k-1}, K, T_{k-1}))
+           plus hedge_PnL = h * (S_k - S_{k-1})
+  4. At expiry: close position at intrinsic value.
+
+  Total cycle P&L = option_premium - (intrinsic_at_expiry + sum_of_theta_adj + hedge_slippage)
+
+  This simulation directly uses ACTUAL price moves, so:
+  - Big moves (jumps) correctly cause large losses
+  - Small/quiet periods correctly generate theta income
+  - Discrete rebalancing frequency exactly matches daily bars
+
+KEY METRICS EXPECTED:
+  - Crypto IV ≈ 60-80%, RV ≈ 40-65%: IV>RV on average → net positive
+  - But crypto has fat tails: occasional -10%/-20% single-day moves devastate short gamma
+  - Expected Sharpe: 0.3–0.8 if honestly modeled (not 4.0)
+
+GATE: Only enter when DVOL/RV_20d >= gate threshold (IV-rich condition).
+GRID: roll_days in {7, 14} x iv_rv_gate in {1.10, 1.20} → 4 configs, 1d TF only.
+
+CAVEAT:
+  - MODELED on DVOL ATM. Skew not modeled (OTM puts have higher IV in practice).
+  - Straddle sell assumes fills at mid; real execution has bid-ask spread.
+  - Tail risk (e.g., BTC -30% day) not captured via DVOL history smoothing.
+  - DVOL history starts 2021-03 → backtest from 2021-03 only.
+  - Lead-only; not for deployment without real options data.
+
+Style: study_weights (continuous modeled position evaluated via standalone P&L series).

+"""OPT06 — Ratio Put Spread (Defensive Short-Vol with Tail Hedge)
+
+IDEA: Ratio put spread (1x2 put ratio) modeled on DVOL:
+  - Sell 1 OTM put at strike K1 = S * exp(-delta1)  (e.g., -0.15 log-moneyness)
+  - Buy  2 OTM puts at strike K2 = S * exp(-delta2)  (e.g., -0.30 log-moneyness)
+  Net: collect premium from the short put, use proceeds to buy tail protection.
+  This is a "defensive short-vol" structure:
+    - Moderate down moves (to K2) → profitable (net premium + short put profit)
+    - Crash moves (below K2) → protected (long 2 puts offset the short)
+    - Up moves → lose net premium received (small cost)
+
+  The ratio 1:2 means the structure has POSITIVE gamma below K2 (net long put delta
+  when S < K2) — the tail hedge kicks in. Above K2 but below K1, it's short-gamma
+  (collects theta). Above K1, it's short a single put (small risk).
+
+GATE: Only enter when DVOL >= gate threshold (elevated IV → richer premium).
+      Also gated on DVOL/RV ratio (only sell vol when IV > RV).
+
+ROLL: Weekly (7d) or biweekly (14d).
+
+GRID: 4 configs:
+  (short_moneyness=-0.10, long_moneyness=-0.25, gate_dvol=50)
+  (short_moneyness=-0.10, long_moneyness=-0.25, gate_dvol=60)
+  (short_moneyness=-0.15, long_moneyness=-0.30, gate_dvol=50)
+  (short_moneyness=-0.15, long_moneyness=-0.30, gate_dvol=60)
+  → 4 configs × 1d TF = 4 backtests (within <=6 limit)
+
+CAVEAT:
+  - MODELED on DVOL (ATM). Real puts have skew (OTM puts cost more → less premium).
+  - History starts 2021-03 (DVOL). Backtest from 2021-03 only.
+  - Tail risk partially mitigated by the ratio structure, but skew model error matters.
+  - Not for deployment without real options pricing data.
+  - Lead-only / modeled.

+"""OPT07 — Collar Overlay
+IDEA: Long spot + buy protective put + sell covered call (zero-ish cost collar).
+  - Long 1 unit spot BTC/ETH
+  - Sell OTM call at strike K_call = S * exp(+call_otm * sigma * sqrt(T))
+  - Buy OTM put at strike K_put  = S * exp(-put_otm * sigma * sqrt(T))
+  Net premium ≈ call premium received - put premium paid (can be near-zero or small debit/credit
+  depending on the strikes chosen).
+
+Goal: reduce drawdown vs buy&hold by capping upside (call) and flooring downside (put).
+      Does this improve risk-adjusted return (Sharpe)?
+
+Hypothesis: the vol risk premium means we receive more on the call than we pay for the put
+(IV > RV historically), so the collar should produce a positive carry vs buying naked insurance.
+In a crash the put activates and limits losses. Net effect should be improved Sharpe.
+
+MODELED: premiums computed via Black-Scholes with DVOL as IV (no skew, no slippage on options).
+DVOL history starts 2021-03 -> backtest from 2021-03 only.
+CAVEAT: modeled, lead-only.

+"""OPT08 — Risk-reversal directional via DVOL-change skew proxy.
+
+HYPOTHESIS: The 25-delta risk reversal sign can be proxied from DVOL changes.
+When DVOL rises sharply relative to recent history (puts bid up = skew bullish for
+downside fear = bearish tilt) we go short; when DVOL falls (fear subsides / calls
+catching up relative = bullish tilt) we go long. We also test the opposite sign to
+be honest about direction. We use DVOL z-score over rolling windows as the signal.
+
+CAVEAT: This is a heavy proxy — DVOL is the ATM vol index, not skew. The actual
+25d risk reversal is not in the data. Results should be treated as suggestive only.
+
+DVOL history: starts 2021-03, so ~4 years of data. FULL window covers 2021-2026.
