feat(dashboard): show SKH01 sleeve in 4-sleeve portfolio view

active_sleeves() already feeds the per-sleeve table & combined metrics, so SKH01
appears automatically. Manual touch-ups: title/docstring -> +SKH01; position label
is now sleeve-aware (the None fallback used to mislabel every pos-fn-less sleeve as
XS01's "book 19 gambe" — now XS01/SKH01/VRP01 get correct labels); footer note adds
SKH01 (quasi-orthogonal @25%, FULL Sharpe 1.68->2.13, DD 14->8%, research/forward-monitor).

+# 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-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).

+# VRP01 + gestione attiva intra-trade — A/B onesto (NEGATIVO)
+
+**Data:** 2026-06-20
+**Script:** `scripts/research/options_vrp_managed.py`
+**Esito:** la gestione attiva del documento credit-spread **distrugge l'edge**. VRP01
+**hold-to-expiry resta superiore.** → scartata.
+
+## Cosa testava
+
+Innesta sul put credit spread di VRP01 le regole intra-trade del doc `strategia-credit-spread-eth`:
+profit-take 50% del credito, stop-loss 1.5× il credito, **VOL-STOP** (chiudi se DVOL sale ≥10 punti
+dall'apertura — regola crypto-specifica nuova), **delta-exit** (chiudi se |delta| short put ≥0.30),
+time-stop 7 DTE. A/B sugli **stessi ingressi gated** (VRP>0 + IV-rank>0.30) e dati certificati;
+MTM giornaliero dello spread via BS sul path certificato + DVOL reale (causale).
+BASE = hold-to-expiry (come VRP01) vs MANAGED = stesso trade gestito.
+
+## Risultato (combo 50/50 BTC+ETH, sleeve-level)
+
+| variante | Sharpe | DD | ret | HOLD Sh |
+|----------|--------|------|------|---------|
+| 14d hold-to-expiry (BASE) | **0.96** | 11.7% | +39% | +1.52 |
+| 14d + solo vol-stop | 0.12 | 10.1% | +3% | +1.01 |
+| 14d FULL managed | **−1.29** | 14.8% | −15% | −1.17 |
+
+Per-asset: la gestione FULL ribalta entrambi (ETH 0.33→−1.15, BTC 1.88→−0.89). Il **delta-exit**
+domina le uscite (18-25 trade su ~33-45) e taglia i vincenti prima della decadenza theta; persino
+il **vol-stop da solo** quasi azzera il ritorno (combo Sh 0.12). Win-rate crolla 80-94% → ~40%.
+
+## Lettura
+
+Per un venditore di premio short-vol l'edge È la decadenza theta tenuta fino a scadenza: ogni
+uscita anticipata (delta, vol-stop, PT) **monetizza meno theta e/o realizza la coda** invece di
+lasciarla riassorbire. Le regole di "difesa" del doc azionario/ETH non trasferiscono al VRP crypto
+modellato: l'unica gestione che non danneggia è **non gestire** (hold-to-expiry, come VRP01 già fa).
+
+**Caveat invariato:** premio MODELLATO su DVOL ATM (no skew) + nessun fill di stress reale → tutto
+ciò resta a livello di LEAD, non deploy. Ma la conclusione relativa (BASE > MANAGED) è robusta
+perché è un A/B sugli **stessi** trade e dati.
+
+## Azione
+
+Nessuna modifica a VRP01 (`sleeves._vrp_combo_returns`, hold-to-expiry). Script conservato come
+riferimento dell'esperimento scartato.

+# Sweep strategie cross-sectional su Hyperliquid (xsec) — 43 script / 257 config
+
+**Data:** 2026-06-20
+**Harness:** `scripts/research/xsec/xslib.py` (nuovo) + 43 script in `scripts/research/xsec/runs/`
+**Verifica:** `scripts/research/xsec/verify_survivors.py` (3 scettici, deterministico)
+**Esito in una riga:** niente di deployabile; il cluster vincente appariscente è **una sola
+scommessa di regime (short alt-beta)**, ma **2 lead genuini** (XM09 trend-gated x-sec momentum,
+XR02 reversal vol-gated) sopravvivono a tutti gli scettici → **forward-monitor, non sleeve.**
+
+## Contesto e motivazione
+
+Dopo che il sweep BTC/ETH a 104 ipotesi (`2026-06-20-alt-strategies-100agent-sweep.md`) ha
+esaurito lo spazio direzionale single-asset confermando il soffitto ~1.3, la frontiera indicata era
+**cross-sectional / multi-asset** sul panel Hyperliquid certificato, dove quel soffitto non vincola
+e dove c'è spazio DISTINTO da XS01 (x-sec momentum semplice sui 19 major).
+
+Nuova harness condivisa `xslib.py`: il panel è N asset × ~810 giorni (universo `all` = **49 alt**
+con ≥700g dopo il fix backfill; `majors` = 19 di XS01). Una strategia = uno **score per-asset
+causale** (dati ≤ close[i]); l'harness lo classifica cross-section ad ogni ribilanciamento, va long
+i top-k / short i bottom-k (market-neutral) o long-only, vol-targeta al 20%, addebita fee sul
+turnover, e — strutturalmente leak-free — il peso deciso a `i` incassa il return di `i+1` (stessa
+convenzione di `src.portfolio` xs_book / `sleeves._xsec_returns`).
+
+**Scoring onesto** (`study_xs`): un candidato guadagna `earns_slot=True` SOLO se
+`full Sharpe>0 AND hold-out 2025+ Sharpe>0 AND marginal_vs(active)=="ADDS" AND corr(XS01)<0.6`.
+`ADDS` a sua volta richiede `holdUplift_w20 ≥ 0.05 AND robust_oos` (uplift hold-out >0.02 **e**
+jackknife drop-one-month tutti positivi). È il marginal scorer del sweep precedente, portato sul
+cross-sectional: si giudica **l'apporto al portafoglio live** (TP01+XS01+VRP01), non lo Sharpe
+assoluto.
+
+**Caveat cotto dentro l'harness:** il panel è **~2.5 anni** (2024-26). Ogni risultato è
+SUGGESTIVO, non robusto come i 6 anni di BTC/ETH. E l'hold-out (2025-26) è **un singolo regime**
+(alt-bear/chop relativo a BTC).
+
+## Find phase — 43 script, 257 sotto-config
+
+11 famiglie cross-sectional: MOM (varianti momentum), REV (reversal), VOL/RISK (low-vol, low-beta,
+BAB, semivarianza, vol-of-vol), DIST (skew/coskew lottery), LIQ (Amihud/turnover/volume),
+VAL (distanza da MA, RSI), STRUCT (double-sort, ensemble z-vote, risk-parity, low-corr, trend-R²,
+lead-lag BTC), UNIV (sweep di universo). **Esito: 42/257 config `earns_slot=True`.**
+
+Sembra molto. Ma **due tell** accomunano quasi tutti gli slot-earner:
+1. corr a TP01 **fortemente negativa** (−0.2…−0.4) — è *per questo* che "aggiungono";
+2. PnL **concentrato nel 2025** (ritorni +22%…+84% nel 2025).

+## Verify phase — 3 scettici (`verify_survivors.py`)
+
+Ipotesi sotto test: *"non sono N edge indipendenti, ma UNA scommessa di regime — short la
+spazzatura high-beta nell'alt-bear 2024-26 — travestita da 30 maschere; il jackknife è robusto solo
+DENTRO quel regime."* Ricostruito il book più forte per famiglia e:
+
+**S1 — matrice di correlazione mutua (>0.6 = stessa scommessa).** Esito SFUMATO:
+- Il cluster low-vol È una sola scommessa: **XV01 = XU02 = 1.00** (identici), XV01↔XV02 0.65,
+  XV01↔XV03 0.67, XV02↔XV03 0.44.
+- MA **XM09, XL02, XS06b, XR02 sono distinti** dal cluster e tra loro (corr media off-diagonale
+  solo **+0.20**, solo 18% delle coppie |r|>0.6). L'ipotesi "tutto una scommessa" è **parzialmente
+  falsa**.
+
+**S2 — carico su short-beta / short-market** (factor di riferimento sullo stesso panel:
+SHORTBETA = book su −beta; SHORTMKT = −market alt equal-weight):
+- **Cluster low-vol = short-alt-beta confermato:** XV03 1.00/0.70, XV01/XU02 **0.67/0.64**,
+  XV02 0.44/0.37. *Non* market-neutral: è un tilt short del mercato alt.
+- **NON short-beta:** XM09 0.08/0.15, XR02 −0.21/−0.18, XL02 0.19/0.26, XS06b 0.36/0.39.
+
+**S3 — Sharpe per anno solare (l'edge è ~solo 2025?):**
+
+| survivor | 2024 | 2025 | 2026 |
+|----------|------|------|------|
+| XV02_lowidiovol | 0.07 | 1.87 | 2.12 |
+| XV01/XU02 lowvol | 1.17 | 1.52 | **−0.09** |
+| XV03_lowbeta | −0.25 | 0.98 | 0.12 |
+| XS06b_lowcorr | 0.26 | 1.34 | 0.32 |
+| **XM09_trendgmom** | **0.82** | **0.50** | **0.74** |
+| XL02_voltrendmom | 0.30 | **−0.14** | **−0.43** |
+| **XR02_revgated** | **0.84** | **0.40** | **2.68** |
+
+## Conclusioni (oneste)
+
+1. **Cluster low-vol / low-beta (XV01, XU02, XV02 in parte, XV03) = tilt short-alt-beta di regime.**
+   S2 lo inchioda (carico 0.44-0.70 su short-market): non è un fattore market-neutral, è "short la
+   spazzatura" mentre gli alt sanguinano vs BTC. XV01/XU02 **già in decadimento (2026 −0.09).** Non
+   può dimostrare di sopravvivere a un flip alt-bull. → **RIGETTATO come sleeve.** Conferma
+   l'osservazione 4874 (XS04b = regime-dependent short-beta tilt) generalizzata all'intera famiglia.
+
+2. **XL02 (vol-trend momentum) = overfit al panel iniziale.** FULL Sharpe più alto (1.83) ma S3 lo
+   uccide: 2025 −0.14, 2026 −0.43. Il numero full è guidato dal 2024, ora è morto. → **RIGETTATO.**
+
+3. **2 LEAD genuini** — distinti (S1), NON short-beta (S2), positivi in **tutti e 3 gli anni** (S3):
+   - **XM09 — cross-sectional momentum gated dal trend di mercato.** Long top-k/short bottom-k alt,
+     attivo solo quando la somma trailing del mercato equal-weight è >0. Sharpe 0.82/0.50/0.74,
+     short-beta-load 0.08, corr TP01 −0.07, uplift hold 0.556 / jackknife 0.355. È il candidato più
+     regime-robusto. **Caveat:** stessa FAMIGLIA di XS01 (x-sec momentum) su universo più largo (49)
+     con gate diverso (trend di mercato vs dispersione) → più un **possibile affinamento di XS01**
+     che una sleeve nuova; corr XS01 0.25, ma marginal scorer dice che ADDS oltre XS01.
+   - **XR02 — short-term reversal gated da alta-vol.** Reversal a 3g attivo solo quando la vol
+     realizzata di mercato è nel regime alto (>p70 espandente). Sharpe 0.84/0.40/**2.68**,
+     short-beta-load −0.21, corr a tutto il resto ~0/negativa, hold-out Sharpe 2.27. Microstruttura
+     reale (overreaction in panico). **Caveat:** H=3 → **turnover alto**; il reversal vive proprio
+     sull'illiquidità che lo rende costoso da eseguire (l'harness addebita fee sul turnover e regge,
+     ma il fill reale su alt minori è ottimistico).
+
+## Perché NON deployabili adesso (caveat trasversali)
+
+- **Panel ~2.5 anni a regime unico.** Anche i 2 lead hanno hold-out = 2025-26 = stesso macro-regime.
+  Suggestivi, non robusti come i 6 anni BTC/ETH.
+- **STAT-MODE di esecuzione.** Un book cross-sectional a 10-19 gambe (long-k+short-k) su alt non è
+  eseguibile col capitale attuale (conto reale ~$600; servono ~$20k per gambe sensate, come già
+  notato per XS01). Sono segnali da monitorare, non ordini.
+- **Lezione confermata (di nuovo):** su un panel corto a regime unico il jackknife drop-one-month
+  certifica la robustezza DENTRO il regime, non ATTRAVERSO i regimi. Il discriminante decisivo è
+  stato **S2 (carico su short-beta) + S3 (consistenza per-anno)**, non lo Sharpe né l'uplift
+  hold-out (che il cluster regime-bet aveva altissimi: upliftHold fino a 1.20).
+
+## Azioni
+
+- **Nessuna modifica al portafoglio live** (TP01 55% + XS01 25% + VRP01 20% invariato).
+- **Forward-monitor** i 2 lead (XM09, XR02) quando il panel HL accumula un secondo regime.
+- **XM09 come affinamento candidato di XS01** (gate trend di mercato + universo 49) da valutare a
+  parità di sleeve, NON come sleeve aggiuntiva, in una prossima iterazione.
+- Harness `xslib.py` + 43 script + `verify_survivors.py` committati come riferimento riusabile.

+# 2026-06-21 — Blind signal fleet: 52 agenti "esperti di segnali" su curve anonime BTC/ETH
+
+## Obiettivo (richiesta utente)
+
+Far partire ~50 subagenti **esperti di segnali** a cui passare lo storico di **ETH e BTC
+in forma ANONIMA** ("senza dire di cosa sono, con curve sovrapposte"): devono trovare come
+**anticipare l'andamento**, liberi di scrivere script o reti neurali ad hoc. L'**orchestratore**
+valuta la validità su **PnL e maxDD**.
+
+L'idea forte del setup cieco: se gli agenti non sanno che sono BTC/ETH, non possono
+pattern-matchare a memoria il crash COVID 2020 / l'orso 2022 / l'halving 2024 — devono trovare
+un timing **trasferibile**, non riconoscere l'era. È anche un test di onestà del metodo: l'edge
+deve reggere su un hold-out che gli agenti non hanno mai visto.
+
+## Setup — harness cieco e leak-free (prima degli agenti)
+
+> 50 agenti su un harness che perde = 50 fantasie (lezione fondante del progetto). Quindi prima
+> l'infrastruttura, poi la flotta.
+
+- `scripts/research/blind/make_blind.py` — esporta BTC/ETH **1d** (via il path certificato
+  `altlib.get`) come **"Series A" / "Series B"**: rebase a **100** (curve sovrapposte, il livello
+  non urla più "$60k bitcoin"), **calendario sintetico** dal 2001 (niente era-crypto da
+  riconoscere), volume normalizzato alla mediana. Split **70% train (visibile agli agenti) / 30%
+  test (solo orchestratore)**. Mapping A=BTC, B=ETH tenuto FUORI dal meta visibile.
+- `scripts/research/blind/blindlib.py` — l'unico modulo che un agente importa. Evaluator
+  leak-free: la posizione decisa a `close[i]` è **shiftata** e tenuta nella barra `i+1` (impossibile
+  leakare moltiplicando un peso per il rendimento della stessa barra), fee su turnover (Deribit
+  0.10% RT). Toolkit di indicatori causali ri-esportati da altlib.
+- **Guardia di causalità automatica** (`causality_ok`): ri-chiama `signal()` su un **prefisso
+  troncato** e pretende che la coda combaci con `signal()` sull'array intero. Qualunque segnale che
+  sbircia il futuro (shift(-k), finestre centrate, fit globale, statistiche full-sample) **diverge →
+  squalificato**. È ciò che rende onesta anche la "rete neurale ad hoc": un modello fittato sul df
+  intero (che a test-time contiene il futuro) fallisce la guardia; passa solo l'expanding/walk-forward.
+- `score_all.py` — il **giudice unico dell'orchestratore**: per ogni modulo gira la guardia, valuta
+  sul **test held-out** A e B, ordina per PnL/maxDD vs benchmark buy&hold.
+- `verify_top.py` — secondo strato avversariale: corr al trend canonico TSMOM, fee-stress 0.20% RT,
+  jackknife drop-block.
+
+Verifica dell'harness: momentum onesto → causale ok, OOS +44% a 19% DD; segnale **deliberatamente
+leaky** (guarda domani) → Sharpe 18 assurdo ma **correttamente squalificato**. Benchmark buy&hold
+OOS sul tail = **−7% PnL, 68% DD, Sharpe 0.22** (il tail 2024-26 contiene un drawdown brutale →
+anticipare il movimento ha spazio reale per vincere).
+
+## Flotta — 52 agenti, 52 ipotesi distinte
+
+Workflow `blind-signal-fleet` (52 agenti in parallelo, ~2h, 2.5M token, 971 tool-call). A ognuno
+**un'ipotesi diversa** (per non riscoprire tutti il momentum): 11 famiglie — trend/TSMOM,
+breakout (Donchian/Keltner/squeeze/pivot/volbreak), mean-rev/oscillatori (RSI/Bollinger/zrev/stoch/
+DPO/WillR), vol-regime (vol-target/regime-switch/ATR-ride/dd-derisk/**vol-of-vol**), struttura
+(HHLL/channel-pos), statistici (Hurst/autocorr/efficiency/skew/entropy), ciclo (FFT/Kalman),
+volume (OBV/PVT/vol-div), **8 ML** (Ridge, logistic, MLP-reg, MLP-clf, GBM, kNN-analog, RLS,
+RandomForest) e 5 meta/ensemble.
+
+**Esito flotta: 52/52 riportati, 52/52 passano la guardia di causalità** (zero look-ahead — la
+disciplina dell'harness ha tenuto su tutta la flotta, ML inclusi).
+
+## Risultati OOS (orchestratore — PnL & maxDD sul test held-out)
+
+Benchmark buy&hold OOS: **PnL −7%, maxDD 68%**. Top per Sharpe-min (peggiore tra A e B):
+
+| # | strategia | PnL_A | PnL_B | DD worst | Sh_min | famiglia |
+|---|---|---|---|---|---|---|
+| 1 | macd | +23% | +19% | **11%** | 0.84 | trend |
+| 2 | accel | +40% | +22% | 12% | 0.79 | trend (2ª diff) |
+| 3 | vol_of_vol | +30% | +32% | 21% | 0.69 | vol-regime |
+| 4 | regime_switch | +25% | +46% | 20% | 0.63 | vol-regime |
+| 5 | rf (ML) | +12% | +8% | **7%** | 0.62 | ML walk-fwd |
+| 6 | obv | +22% | +20% | 16% | 0.60 | volume |
+
+Tutti i top sono varianti **trend/vol-regime**. Mean-reversion e ML (logistic/gbm/mlp) in fondo →
+ri-conferma cieca di "mean-rev morto" e "ML walk-forward debole" del progetto. Lo **Sharpe OOS ~0.84
+decade dal train ~1.4** (firma classica di overfit/regime). Ma vs buy&hold (−7%/68% DD) i top trend
+**ribaltano il segno e tagliano il DD ~3-6×**: è il valore reale, identico alla lezione TP01.
+
+## Verifica avversariale — 3 scettici indipendenti (REFUTE, non confirm)
+
+1. **Regime-luck** → **REFUTED ×3.** I top-5 bar su ~800 OOS forniscono il **67-102% di tutto il
+   PnL**; togliendo 10 bar la serie va **negativa**; `accel` crolla nel terzo finale (COMB Sharpe
+   **−1.21**); A e B non concordano su *quando* funziona. Edge concentrato, non distribuito.
+2. **Trend-redundancy** → **REFUTED ×4.** Regressione `cand ~ α + β·TSMOM` (Newey-West HAC):
+   **t(α) = +0.92..+1.51, nessuno supera 1.96**. corr-al-trend 0.34-0.74, β 0.45-0.73; media residua
+   +0.05-0.08/anno = rumore. Sono TSMOM meglio tarati, **non alpha ortogonale**; contro il TP01 reale
+   (~1.3) il margine svanisce.
+3. **Overfit/robustezza** → MACD **non-refuted** (plateau vero a un asse, 0% celle <0.5) ma Sharpe OOS
+   onesto **0.84, non 1.40** (numero da docstring = in-sample). `accel` **REFUTED** (il termine di
+   accelerazione, la sua tesi, **danneggia** l'OOS; LAG knife-edge: −20% → −63% Sharpe; corner
+   congiunti negativi). `vol_of_vol` **REFUTED** (gate threshold-fit: PCTL 0.80→0.60 distrugge il 73%
+   dello Sharpe OOS). Fee = drag secondario ~10%, non il killer; il killer è la sensibilità ai parametri.
+
+## Verdetto
+
+**52 agenti ciechi, orchestratore che valuta PnL e maxDD su hold-out, e NIENTE di nuovo
+sopravvive alla verifica avversariale.** Ogni "vincitore" è trend-beta di due curve strutturalmente
+rialziste; soffitto Sharpe OOS **~0.84** su questo singolo hold-out; nessun alpha statisticamente

+# 2026-06-21 — Asse intraday/microstruttura: il lead più vicino al reale, ma NON deployabile
+
+## Perché (utente: "cerchiamo qualcosaltro")
+
+Direzionale e relative-value su BTC/ETH esauriti (flotte blind + ortho). L'unico asse mai
+sfruttato dopo il reset = il **tempo intraday** (feed certificati 5m/15m/1h; tutto era a 1d).
+Meccanismi diversi da trend e relative-value: bias ora/sessione (perp con funding a 00/08/16 UTC),
+reversione post-evento (vol/volume/gap), breakout del range del giorno prima.
+
+## Setup
+
+`scripts/research/intraday/intra_score.py`: wrappa `altlib.study_marginal` a un TF a scelta
+(compone i rendimenti intraday a daily, li valuta col **marginal scorer indurito** = multi-cut +
+edge-in-sample + hedge-vs-alpha) e riporta **turnover + fee-sweep a 0.20% RT**. Il muro: a 0.10% RT
+il churn intraday è morte (un flip orario fa 2152 trade/anno → −8.6 Sharpe netto). Vincolo agli
+agenti: **basso turnover**, l'intraday come informazione (timing/sizing/gating), non HFT.
+
+## Flotta — 16 agenti
+
+16 ipotesi low-turnover. Esito grezzo: 16 riportati, **10 "earns_slot"** (di nuovo gonfiato).
+
+## Diagnosi orchestratore — separare ortogonale vero da trend-beta
+
+Per corr-a-TP01 (`meta_intra.py`): 2 sono **trend-beta** (close_location 0.81, trend_quality 0.75 —
+Sharpe in-sample alto ma preso in prestito dal trend), 3 **mixed**, **5 genuinamente ortogonali**
+(|corr|<0.4): open_drive (0.13), prevday_range_breakout (0.15), vol_event_revert_15m (−0.1),
+volume_spike_revert (0.14), gap_fill (0.04) — 2 famiglie (breakout-continuation + capitulation-revert),
+mutuamente de-correlate. **Combo dei 5: Sharpe standalone 1.80, corr-TP01 0.17, uplift +0.33/+0.27/
++0.34/+0.34/+0.53 a OGNI cut** (non solo 2025).
+
+## Gauntlet deterministico (`verify_intra.py`) — passa TUTTO ciò che uccise le onde precedenti
+
+- **In-sample pre-2025 Sharpe 1.75; uplift pre-2025-ONLY +0.281** (l'ortho faceva +0.027 = null).
+- **Walk-forward selection** (scegli su solo passato, testa avanti): **+0.303 / +0.368** (l'ortho dava −0.07).
+- **Drop-one robusto** (+0.24..+0.31 pre-2025), **fee-robusto a 0.30% RT**, **leak-free**
+  (online-consistency: max_tail_diff = 0.0 su tutti e 5). Sembrava IL lead.
+
+## Verifica avversariale (3 scettici indipendenti) — il verdetto vero
+
+1. **Execution/microstruttura:** **open_drive = ARTEFATTO di etichettatura UTC.** Spostando il
+   confine del giorno di 4h l'uplift va NEGATIVO (−0.10); togliendo l'ancora UTC (trailing-8h) Sharpe
+   0.01; funziona solo a 00:00 UTC, solo alle ore 3 e 7. **Scartare.** `prevday_range_breakout` invece
+   **REGGE** (plateau su k, robusto allo shift del confine, fill eseguibili a close) = unico candidato
+   onesto, ma la decorrelazione viene tutta dalla gamba SHORT che si appoggia al regime down 2025-26;
+   anchor=1 only. **Caveat $600:** il vol-target fa ~8500 ribilanciamenti/anno, 97-98% < $1 di nozionale
+   → la fee proporzionale modellata su trade infinitesimi è **finzione** a $300/gamba (vale anche per TP01).
+2. **Hedge + tail:** **REFUTED.** L'uplift pre-2025 +0.281 sta al **20-24° percentile del null di un
+   asset a corr-zero** (mediana null +0.371) — essendo a corr +0.175 (non 0) e bassa vol, **aggiunge
+   MENO del rumore scorrelato**. È **hedge** (corr Sharpe-TP01/uplift −0.57..−0.80; TP01-down uplift
+   +0.79 vs TP01-up +0.20) e **tail-luck** (le gambe revert: top-5 giorni = 76-83% del PnL, <10
+   eventi/anno, front-loaded 2019-21; combo: metà uplift in ~10 giorni).
+3. **Overfit/robustezza:** **ROBUST-PLATEAU** (243-cell joint grid pre-2025 uplift min +0.134/med
+   +0.211, 99% celle >+0.15; ogni anno positivo). MA segnala lui stesso il **null-pctl 0.20**: "il
+   beneficio è la matematica di diversificazione di uno stream ortogonale a Sharpe 1.75, NON timing-alpha
+   specifico-TP01" + storia corta sulle gambe revert + fill modellati vs reali.
+
+## Verdetto
+
+**Niente in live.** L'asse intraday ha prodotto il lead **più vicino al reale** di tutta la ricerca,
+ma sotto 3 scettici: **open_drive è artefatto** (UTC-labeling); la combo **fallisce il null a
+corr-zero** (aggiunge meno del rumore), è **hedge-shaped** e **tail-luck**; e lo Sharpe modellato è
+gonfiato dal micro-ribilanciamento sub-dollaro a $600. Lo Sharpe standalone 1.80 NON è affidabile
+(artefatto + coda + finzione di fill). **Resta solo TP01.**
+
+**Lead reale (forward-monitor, non deploy):** `prevday_range_breakout` — l'unico segnale sopravvissuto
+allo scettico d'esecuzione (breakout del range del giorno prima, eseguibile, leak-free), con caveat
+short-leg/regime-2025. Trattamento = come `dvol_spread` / XS01 / STA05.
+
+### Lezioni harness — CODIFICATE (il vero ritorno)
+
+1. ✅ **`altlib.day_boundary_robust(target_fn, tf)`** — shifta il confine del giorno UTC e ri-misura
+   l'uplift marginale: INVARIANT (segnale di prezzo, spread 0) / ROBUST (effetto calendario vero,
+   resta positivo) / **ARTIFACT-RISK** (l'uplift si inverte = etichettatura). Verificato: riproduce
+   da solo il verdetto degli scettici — open_drive → ARTIFACT-RISK (+0.23→−0.33), prevday_breakout
+   → ROBUST. Test `tests/test_harness_realism.py`.
+2. ✅ **`altlib.eval_weights_smallcap(df, target, capital=600, min_order=5)`** — salta i
+   ribilanciamenti sub-min_order (la finzione del micro-trading a $600), riporta lo Sharpe haircut
+   reale vs modellato. Vale per ogni sleeve a questo capitale, TP01 incluso. Test idem.
+3. ✅ **`altlib.causality_ok(target_fn, tf)`** — guardia look-ahead/online-consistency (ricalcola
+   il target su un prefisso e pretende che la coda combaci con il full): eval_weights shifta la
+   posizione ma NON vede una feature non-causale (finestra centrata / shift(-k) / stat full-sample).
+   Integrata in `intra_score` (un leak è squalificato prima dello scoring). + il calendar-artifact
+   gate (`day_boundary_robust`) ora gira dentro `intra_score`: **open_drive/weekly_seasonality/
+   overnight → CAL-ARTIFACT, fuori dagli slot da soli**; prevday_breakout resta (ROBUST). Il lab
+   intraday ora auto-becca leak e artefatti-calendario che ieri richiedevano gli scettici. Test idem.

+# 2026-06-21 — Caccia all'ORTOGONALE a TP01: relative-value BTC/ETH (eseguibile a $600)
+
+## Perché (richiesta utente: "cerca ortogonale a TP01")
+
+La flotta cieca (stesso giorno) ha confermato: niente di NUOVO in direzionale BTC/ETH — tutto è
+trend-beta di TP01 (soffitto ~1.3). L'unica via a un nuovo slot LIVE è un meccanismo **ortogonale**
+(bassa correlazione, alpha residua). Il più promettente **eseguibile al capitale reale ~$600** è un
+**book RELATIVE-VALUE a 2 gambe BTC/ETH** (long una / short l'altra), grosso modo market-neutral →
+correlazione naturale bassa col trend, e a 2 gambe è eseguibile (a differenza del book a 19 gambe di
+XS01 che serve ~$20k).
+
+## Setup — ortho-lab + giudice MARGINALE (non Sharpe assoluto)
+
+`scripts/research/ortho/ortholib.py`: BTC/ETH 1d allineati su date comuni; `eval_book(book_fn)` con
+`book(btc,eth)->(w_btc,w_eth)`, **shift di entrambe le gambe** (no leak), fee su entrambe, serie netta
+**giornaliera**; guardia di causalità online; check **eseguibilità a $600** (max gamba ≤ 0.5 = cap
+$300/asset). Il giudice è `altlib.marginal_vs_tp01`: **corr a TP01, uplift OOS del blend, alpha
+residua, robust_oos** (clean-year + jackknife drop-month). Verdetto = ADDS, **non** Sharpe assoluto.
+`ortho_score.py` (giudice), `meta_ortho.py` (corr mutua + persistenza multi-cut), `sleeve_rv.py`.
+
+Sanity: ratio-momentum → ADDS (corr 0.05); ratio-mean-reversion → DILUTES. L'harness discrimina.
+
+## Flotta — 18 agenti relative-value (~40 min)
+
+18 ipotesi distinte: ratio-momentum multi-orizzonte, XS a 2 asset, beta-neutral residuo, Donchian
+sul ratio, EMA-cross, accel, carry lento, Kalman-spread, gate-correlazione, gate-vol, inverse-vol,
+rebalance-harvest, lead-lag, **DVOL-spread**, **VRP relativo**, dispersione, ensemble.
+
+**Esito grezzo: 18 riportati, 17 "ADDS / earns_slot".** → **bandiera rossa**: non esistono 17 alpha.
+Gli agenti stessi l'hanno annotato ("hold-out corto ~537g", "uplift dipende dal regime ETH-bleed
+2025", "forward-monitor non full-weight").
+
+## Diagnosi dell'orchestratore — il "17 slot" è gonfiato
+
+1. **Una scommessa o tante?** corr mutua media **0.43** → collassano a **8 rappresentanti**
+   de-correlati. Non 17, non 1.
+2. **Persistente o solo finestra 2025?** `marginal_vs_tp01` fissa l'hold-out al 2025-01-01 = proprio
+   la finestra dove ETH ha perso vs BTC e TP01 è debole. Ri-misurando l'uplift a **più cut**
+   (2022/23/24/25): il basket selection-free era +0.06/+0.06/+0.11/+0.38 (positivo ovunque ma
+   crescente verso il 2025). Smaschera anche i **falsi** che il robust_oos fisso-2025 non vede:
+   `kalman_spread` (−0.14/−0.16/−0.10 poi +0.37) e `xs2_zscore` sono **2025-only**.
+3. **Selezione walk-forward (senza hindsight):** scegliere i top-4 per uplift sul **solo passato** e
+   testare in avanti → uplift **−0.07** (sel <2023) / +0.05 (<2024) / +0.43 (<2025). **Scegliere la
+   variante vincente in anticipo è inaffidabile**; il mio "curated 4" è in parte hindsight.
+
+## Verifica avversariale (scettico indipendente) — REFUTED
+
+Sul **basket selection-free** (equal-weight di tutti i book market-neutral, NESSUN cherry-picking):
+- standalone Sharpe **0.61**, maxDD 15%, **corr a TP01 0.05** (genuinamente ortogonale).
+- **uplift full +0.078 = pre-2025 +0.027 / solo-2025+ +0.401.** Il pre-2025 **+0.027 sta al 49°
+  percentile di 500 asset-rumore a corr-zero** (+0.029 per costruzione) → è **matematica di
+  diversificazione, non segnale**.
+- **corr(Sharpe annuo TP01, uplift annuo basket) = −0.87**; condizionato: TP01 su → +0.014, TP01 giù
+  → +0.369. **È un hedge dei drawdown di TP01, non un premio autonomo.** Paga nel 2022 (orso) e
+  2025-26 (ETH-bleed) — i due anni peggiori di TP01 — rumore altrove (2023 −0.06, 2024 −0.12).
+- Block-bootstrap P(uplift>0): full 90%, **pre-2025 66% (testa o croce)**, 2025+ 99%.
+- Fee: a **0.30% RT il pre-2025 va NEGATIVO** (−0.021); sopravvive solo il numero del regime 2025.
+- Eseguibilità OK ($264/gamba, turnover 12/yr) — non è quello il problema.
+
+## Verdetto
+
+**Niente di questa flotta merita uno slot LIVE.** Il meccanismo relative-value BTC/ETH è REALE e
+genuinamente ortogonale (corr ~0.05), ma è un **hedge della debolezza di TP01 travestito da alpha**:
+il suo contributo pre-2025 è indistinguibile da un asset-rumore a corr-zero (49° percentile del null)
+e muore a fee realistiche; l'unico payoff vero è una singola finestra di 537 giorni (2025-26).
+Deployarlo = deployare un backtest mono-regime. **Resta live solo TP01** (l'unica cosa che supera
+tutto questo scrutinio). Coerente con XS01 (stessa famiglia cross-sectional): diversificatore
+da monitorare, non alpha da eseguire — e la versione a 2 asset è ancora più sottile della 19-gambe.
+
+### Valore metodologico (cosa resta, ed è importante)
+
+- **Il marginal scorer fisso-2025 è ingannabile** (17/18 "ADDS"). Ciò che ha ucciso i falsi positivi:
+  **persistenza multi-cut** + **selezione walk-forward** + **bootstrap vs null a corr-zero**. Lezione
+  da cablare nello scorer: testare PIÙ cut e confrontare l'uplift col **null di un asset-rumore
+  ortogonale** (un'asset scorrelato con drift positivo "aggiunge" +0.03 per pura matematica — non è
+  un edge). Un basso-corr che paga solo quando il core è debole è un **hedge**, va prezzato come tale.
+- Lab riusabile: `ortholib`/`ortho_score`/`meta_ortho` (giudice marginale + persistenza). I 18 book +
+  `sleeve_rv.py` (curated, **selection-biased — non deployare**) restano come riferimento.
+
+File: `scripts/research/ortho/{ortholib,ortho_score,meta_ortho,sleeve_rv}.py`,
+`agents/agent_00..17_*.py`, `ortho_leaderboard.json`, skeptic `skeptic_{basket,regime,null}.py`.
+
+## AGGIORNAMENTO — lezione codificata in `altlib.marginal_vs_tp01` (stesso giorno)
+
+I tre gate sono ora **codice**, non solo prosa (test `tests/test_marginal_scorer.py`, +5 test):
+1. **persistenza multi-cut** (`multicut_uplift`/`multicut_persistent`): uplift a ogni inizio anno,
+   non solo all'HOLDOUT fisso → uccide i 2025-only (es. `kalman_spread`, negativo a ogni cut pre-2025).
+2. **edge in-sample** (`has_insample_edge`): lo Sharpe standalone PRE-holdout dev'essere ≥0.5. È il
+   discriminante onesto (la basket faceva 0.29). I `null_pctl_*` (vs asset-rumore a corr-zero) restano
+   come CONTESTO — mostrano che un low-corr "aggiunge" ~+0.03 per matematica, vero per sleeve buoni e
+   cattivi, quindi non possono essere IL gate; l'edge in-sample sì.
+3. **hedge vs alpha** (`is_hedge`): `corr(Sharpe-TP01, uplift annuo)` molto negativa + paga solo
+   quando TP01 è giù → HEDGE, non alpha.
+
+Verdetti nuovi **HEDGE** e **NOISE**; `earns_slot` ora pretende ADDS + robust_oos + has_insample_edge
++ not is_hedge. **Sull'onda ortho lo scorer indurito ribalta 17/18 "ADDS" → 1** (`dvol_spread`, unico
+con edge in-sample reale 0.57; gli altri 16 → NOISE/HEDGE). Controllo: un sleeve sintetico Sharpe~1.3
+scorrelato resta **ADDS** (non rigetta i diversificatori veri — XS01-like). La verifica avversariale
+di 3 giorni è ora una chiamata di funzione.

+# PREVDAY block-bootstrap — coda-fortuna vs persistente (blocker #2/#3)
+
+**Data:** 2026-06-21 (chiude la trilogia: fill-haircut → turnover/hedge → bootstrap)
+**Script:** `scripts/research/intraday/prevday_bootstrap.py`
+**Esito:** PREVDAY-full **non** è più coda-fortuna di TP01 e l'edge è **bootstrap-robusto** (full
+99% / hold-out 93% dei resample con uplift>0). MA la gamba short (= tutto il valore) è
+**tail-dipendente** (top-5 giorni = 130% del suo netto). PREVDAY = tail-hedge legittimo dal payoff
+grumoso. Resta forward-monitor.
+
+## Chiarimento di scope
+
+Il "top-5 giorni = 76-83% del PnL" del diario intraday era sulle GAMBE REVERT del combo a 5 segnali
+(vol_event/volume_spike/gap_fill), poi SCARTATE. Il sopravvissuto è PREVDAY (breakout-continuation).
+Qui si testa PREVDAY STESSO — e la sua gamba SHORT, che (prevday_turnover) è l'intero valore di
+portafoglio. Block bootstrap circolare (blocchi 20g, B=3000) per preservare autocorrelazione/regime.
+
+## [A] Concentrazione del PnL nei top-K giorni
+
+| serie | n | totRet | top5 | top10 | top20 | giorni→50% gain |
+|-------|--:|-------:|-----:|------:|------:|----------------:|
+| PREVDAY full | 2869 | +182% | 22% | 36% | 59% | 411 (14.3%) |
+| **PREVDAY short-only** | 2869 | **+28%** | **130%** | 218% | 345% | 312 (10.9%) |
+| PREVDAY long-only | 2869 | +154% | 18% | 30% | 49% | 287 (10.0%) |
+| TP01 (riferimento) | 2657 | +116% | 19% | 33% | 55% | 213 (8.0%) |
+
+- **PREVDAY-full NON è più coda-fortuna di TP01**: top5 22% vs 19%, e per il 50% del guadagno serve
+  *più* tempo (14.3% dei giorni vs 8.0% → più distribuito). Il tail-luck del diario era sulle gambe
+  revert scartate, non su PREVDAY.
+- **Gamba short tail-dipendente:** top5 = **130% del netto** → togliendo i 5 giorni migliori la short
+  va in perdita (gli altri 2864 giorni nettano −8%). Sono i giorni-crash dove la short paga.
+
+## [B] Circular block bootstrap (20g, B=3000)
+
+| campione | PREVDAY Sharpe (mediana [5°,95°], %>0) | blend 80/20 uplift (mediana [5°,95°], %>0, %>+0.10) |
+|----------|----------------------------------------|------------------------------------------------------|
+| full (2018-08→2026-06) | +1.24 [+0.64,+1.80] 100% | +0.28 [+0.09,+0.47] 99% / 93% |
+| hold-out (2025+) | +1.27 [−0.01,+2.46] 95% | +0.53 [−0.05,+1.21] 93% / 88% |
+| short-only hold-out | +1.12 [−0.32,+2.41] 90% | +0.53 [−0.08,+1.31] 92% / 87% |
+
+- **Full sample: edge robustissimo** — 99% dei resample dà uplift>0 (mediana +0.28). Non è "un blocco
+  fortunato".
+- **Hold-out: regge con coda più larga** (5° pctl appena negativo: hold-out corto ~536g + short
+  tail-dipendente), ma 93% dei resample >0, 88% >+0.10.
+
+## Verdetto blocker #2/#3
+
+- **#3 tail-luck — DECLASSATO per PREVDAY-full, CONFERMATO per la gamba short.** La strategia intera
+  non è più concentrata di TP01 (che già deployamo); il motore di valore (la short) sì: vive su <10
+  giorni-crash/anno. Bootstrap-robusto (non un singolo blocco), ma il forward sarà GRUMOSO, non un
+  liscio +0.56/periodo.
+- **#2 null-corr-zero — RIDIMENSIONATO.** L'uplift è genuinamente positivo (93-99% dei resample), non
+  rumore; il punto era di *efficienza relativa* (rende meno di un ipotetico asset perfettamente
+  scorrelato), non di esistenza dell'edge.
+
+## Sintesi della trilogia (fill-haircut + turnover/hedge + bootstrap)
+
+PREVDAY, dopo tre attacchi avversariali:
+1. **Eseguibile alla taglia reale** ($600): haircut di fill +0.01 (blocker #4 smontato).
+2. **Già a turnover efficiente**: ridurlo erode l'edge; nessuna ottimizzazione (config congelata).
+3. **È un HEDGE, non alpha**: tutto il valore è la gamba short → tail-hedge di regime-down, additivo
+   alla flat-stance di TP01 (blocker #1 inchiodato).
+4. **Edge bootstrap-robusto** ma **payoff grumoso** (il valore è in pochi giorni-crash) (blocker #3
+   declassato sul full, confermato sulla short; #2 ridimensionato).
+
+→ **Candidato tail-hedge legittimo**, non sleeve-alpha. Resta in FORWARD-MONITOR: la domanda forward
+non è più "è eseguibile / è overfit", ma **"la gamba short continua a pagare nei prossimi crash fuori
+da 2022 e 2025-26?"**. Se sì → si valuta come overlay di tail-hedge (peso piccolo, atteso payoff
+lumpy); se no → era beta-corto del regime down 2025-26.

+# PREVDAY fill-haircut a basso capitale — il blocker d'esecuzione è BENIGNO (1/4 smontato)
+
+**Data:** 2026-06-21 (follow-up di `2026-06-21-intraday-microstructure.md`)
+**Script:** `scripts/research/intraday/fill_haircut.py`
+**Esito:** l'haircut del fill reale a $600 è **+0.01 Sharpe** (trascurabile). Lo scettico

+restano → PREVDAY resta in **forward-monitor, non deploy**.
+
+## Domanda
+
+Lo scettico d'esecuzione dell'onda intraday aveva segnalato: il vol-target di PREVDAY fa ~8500
+ribilanciamenti/anno per gamba, 97-98% < $1 di nozionale a $600; a quel capitale (min_order $5) NON
+puoi piazzarli, quindi il libro MODELED (ribilanciamento continuo, frictionless) è una finzione e lo
+Sharpe modellato è gonfiato. Il forward-monitor traccia MODELED-$2000 vs REAL-$600 per misurarlo nei
+mesi a venire — qui lo stimiamo SUBITO su tutto lo storico, replicando la STESSA logica dei due libri
+di `paper_prevday.py` ma sull'intero path 1h (2019-03 → 2026-06, 63.732 barre).
+
+Due libri identici tranne il fill:
+- **MODELED**: ribilancia ad ogni barra (fee proporzionale su ogni |Δ|).
+- **REAL-$C**: salta i ribilanciamenti con nozionale `|Δpos|·leg_cap < $5` (posizione stale →
+  tracking error, ma niente fee sui trade infinitesimi). Sweep C ∈ {600, 2000, 20000}.
+
+## Risultati

+
+## Lettura
+
+Saltare il **98.4%** dei micro-ribilanciamenti a $600 non costa quasi nulla perché quei trade sono
+*individualmente infinitesimi*: sia la fee risparmiata sia il tracking-error introdotto sono
+trascurabili. Il PnL è dominato dai ~50 flip di direzione/anno + la deriva lenta del vol-target, che
+il libro $600 cattura comunque sui movimenti grandi (la fee-drag passa solo da 2.49% a 2.39%). La
+"finzione della fee sub-dollaro" è quindi **benigna**: non gonfia lo Sharpe modellato (MODELED e
+REAL-$600 coincidono a ±0.01). NB: lo Sharpe **non si degrada** scendendo di capitale → l'edge
+modellato di PREVDAY è eseguibile alla taglia reale; il blocker era altrove.
+
+## Conseguenza sul verdetto
+
+Dei 4 blocker che tenevano PREVDAY fuori dal deploy, il **#4 (fill a basso capitale) è SMONTATO**.
+Restano in piedi i 3 strutturali (dall'onda intraday, non rivalutati qui):
+1. **hedge-shaped** — l'uplift viene dai regimi TP01-down (uplift +0.79 TP01-down vs +0.20 TP01-up);
+2. **fallisce il null a corr-zero** — uplift pre-2025 al 20-24° pctl del null di un asset random
+   scorrelato (aggiunge MENO del rumore);
+3. **tail-luck** — top-5 giorni = 76-83% del PnL delle gambe revert, <10 eventi/anno.
+
+PREVDAY resta il lead **più solido sull'esecuzione** di tutta la ricerca post-reset (il dubbio più
+"fisico" è caduto), ma **forward-monitor, non deploy**, finché il track record forward non scioglie
+hedge/coda/null. Lezione harness: `eval_weights_smallcap` (il gate min-order) va sempre eseguito
+PRIMA di scartare un lead per "fill irreale" — qui avrebbe evitato di sopravvalutare il blocker #4.

+# PREVDAY come overlay di tail-hedge sul portafoglio — simulazione d'impatto (NON deploy)
+
+**Data:** 2026-06-21 (segue la trilogia fill-haircut / turnover-hedge / bootstrap)
+**Script:** `scripts/portfolio/prevday_overlay.py`
+**Esito:** a peso 10%, PREVDAY taglia il maxDD FULL del portafoglio **14.3% → 9.9% (−31%)** e alza
+l'hold-out Sharpe **1.66 → 1.97 (+0.31)**. 10% è vicino all'ottimo di DD. MA è tutto IN-SAMPLE: il
+prize si materializza solo SE l'edge di PREVDAY persiste forward. PREVDAY resta FORWARD-MONITOR.
+
+## Setup
+
+Simulazione che NON tocca il registry di produzione: prende il portafoglio attivo (TP01 55% + XS01
+25% + VRP01 20%), riscala i tre sleeve a (1−W) mantenendone le proporzioni, e aggiunge PREVDAY a
+peso W. Sweep W ∈ {0,5,10,15,20%}. PREVDAY = libro 1h breakout-continuation, parametri congelati,
+50/50 BTC+ETH, fee 0.10% RT. Outer-join del portafoglio: PREVDAY dal 2018, VRP01 dal 2021, XS01 dal
+2024 → nel 2019-20 PREVDAY pesa di fatto >W (solo TP01 accanto); nell'hold-out 2025+ (tutti e 4
+attivi) pesa esattamente ~W → **l'HOLD-OUT è il confronto pulito a "10%"**.
+
+## Sweep peso overlay
+
+| peso PREVDAY | FULL Sharpe | FULL DD | HOLD Sharpe | HOLD DD | HOLD ret |
+|--------------|------------:|--------:|------------:|--------:|---------:|

+
+(PREVDAY standalone: FULL Sh 1.23 / DD 26.7%; HOLD Sh 1.28 / DD 10.8%.)
+
+## Lettura a 10%
+
+- **FULL: Sharpe +0.20 (1.68→1.88), maxDD 14.3%→9.9% (−4.4pp ≈ −31%).** Comportamento da tail-hedge:
+  la gamba short ammortizza i crash storici (2019-21, 2022).
+- **HOLD-OUT: Sharpe +0.31 (1.66→1.97), ret +16.7%→+19.0%, DD 3.4%→3.3% (già bassissimo).** Nel
+  regime recente il beneficio è rendimento/Sharpe, non taglio DD.
+- **10% ≈ ottimo di DD.** Oltre, lo Sharpe sale ancora (1.93→1.95) ma il maxDD FULL smette di
+  scendere (10.3→10.6%): stai solo aggiungendo rischio direzionale short. Argomento per ~10% in
+  chiave hedge (massimizza il taglio-coda per unità di rischio aggiunto).
+
+## Per anno (baseline → overlay 10%)
+
+| anno | ret | DD |
+|------|-----|----|
+| 2019 | +11.3 → +15.2 | 10.3 → 8.2 |
+| 2020 | +51.1 → +53.1 | 8.4 → 6.3 |
+| 2021 | +32.5 → +28.3 | 5.2 → 4.3 |
+| 2022 | −3.0 → −1.6 | 3.7 → 3.0 |
+| 2023 | +11.2 → +11.4 | 9.2 → 9.9 |
+| 2024 | +24.4 → +25.7 | 3.9 → 3.4 |
+| 2025 | +12.0 → +12.0 | 3.4 → 3.3 |
+| 2026 | +4.2 → +6.2 | 2.6 → 2.2 |
+
+Migliora o pareggia quasi ovunque; costa solo nel toro 2021 (premio d'assicurazione atteso per un
+hedge) e leggermente sul DD 2023; paga nel bear 2022 e nel 2026.
+
+## Verdetto
+
+L'overlay 10% è **attraente in simulazione** — taglia il drawdown FULL di ~31% e alza l'hold-out
+Sharpe +0.31, con 10% vicino all'ottimo di DD. Ma:
+1. **È in-sample.** I guadagni assumono che l'edge di PREVDAY persista — il forward-monitor esiste
+   proprio per verificarlo. Questa simulazione quantifica il PRIZE, non lo prova.
+2. **Outer-join:** il taglio-DD storico è gonfiato dal peso effettivo >10% nel 2019-20; il read
+   pulito a 10% è l'hold-out (prize = Sharpe +0.31).
+3. Incidentale: il 3-way TP01+XS01+VRP01 baseline qui fa FULL 1.68 / HOLD 1.66.
+
+**Azione: nessuna.** PREVDAY resta FORWARD-MONITOR (registry di produzione invariato). Quando il
+track record forward avrà ~2-3 mesi, ri-valutare l'overlay 10% con la stessa metrica (taglio-DD +
+hold-out Sharpe) su dati VERAMENTE fuori campione. Lo script è il riferimento per quel confronto.

+PREVDAY è un **hedge di regime-down**, non alpha. Resta forward-monitor.
+
+## Premessa (da fill_haircut)
+
+Il libro REAL-$600 salta il 98.4% dei ribilanciamenti del vol-target e la fee-drag scende solo
+2.49% → 2.39%/anno. Quindi la fee (~2.6%/anno) NON viene dal churn sub-dollaro ma dai **~70 flip di
+direzione/anno**. Un deadband d'esecuzione è inutile; l'unica leva è ridurre i flip a LIVELLO DI
+SEGNALE. Qui sweep delle leve (buffer, anchor, min-hold) + long-only vs long-short. Libro MODELED
+(l'haircut di fill è +0.01, irrilevante). Metrica che conta = **uplift hold-out del blend 80/20**.

+- **Allargare buffer/anchor taglia fee e turnover ma l'uplift cala monotonicamente** (k: 0.56→0.40→

+  l'edge: meno flip = meno edge.
+- **min_hold=24h** è l'unico ritocco "quasi gratis" (uplift +0.56→+0.60 a parità di fee) ma
+  **peggiora il DD −27%→−32%** → non vale cambiare una strategia congelata in forward-monitor.

+
+La versione **long-only ha Sharpe standalone più ALTO** (1.55 vs 1.23) ma è **correlata +0.64 a TP01
+e non aggiunge quasi nulla al blend** (+0.09). **Tutto il valore di portafoglio viene dalla gamba
+SHORT:** la short *abbassa* lo Sharpe standalone (shortare crypto nel toro 2019-24 perde) ma fornisce
+**tutta** la decorrelazione (corrTP 0.64→0.15) e l'uplift hold-out (0.09→0.56).

+nell'orso (2022, 2025-26 down/chop). È additivo a TP01, che va *flat* nel risk-off ma non *short*.
+Questo conferma e affina il blocker #1 dell'onda intraday ("l'uplift viene dai regimi TP01-down"):
+non è solo conditional sui regimi down, è **interamente la gamba short** = una scommessa direzionale

+
+## Obiettivo (goal utente)
+Usare >=50 agenti per prendere l'anticipazione crypto->equity e trovare la MIGLIORE soluzione,
+provando diversi mercati e timing, su piu' anni.
+
+## Setup
+- **Dati**: universo IB esteso a **26 ETF certificati** (azioni US/settori/intl/bond/credito/oro/
+  commodity/REIT), cache su disco (`fetch_ib_equities.py` + BROAD2). Crypto BTC/ETH 1h (Deribit).
+- **Harness onesto** (`crypto_lead_harness.py`): per ogni sessione equity, lead = crypto nella
+  finestra equity-CHIUSO [P 21:00 -> D 13:00 UTC] (overnight; il weekend e' il caso lungo). Predice
+  gap/intraday/full. Metriche: corr, **t incrementale vs sessione equity precedente**, Sharpe
+  eseguibile (sign(lead)*predict, net costi) FULL/IS/OOS, **hit per-anno**.
+- **Workflow** (`wf_crypto_lead.js`): grid 416 config (2 lead × 26 mercati × 2 giorni × 2 predict ×
+  2 finestre). **52 agenti sweep** -> **12 agenti verifica avversariale** (stress 10bps + OOS 2024+ +
+  multi-anno) -> **1 sintesi**. Totale **65 agenti**, 1.7M token.
+
+## Risultato
+
+### Fenomeno fortissimo: crypto overnight -> GAP di apertura equity
+Cluster coerente in cima, TUTTI predict=gap/overnight, su ogni target risk-on:
+| lead->target | t-incr | Sh OOS@4bps | @10bps | OOS-recente | anni+ |
+|---|---|---|---|---|---|
+| ETH->IWM gap | 17.1 | 2.49 | 1.96 | 2.41 | 7/8 |
+| ETH->QQQ gap | 17.9 | 2.36 | 1.83 | 2.31 | 7/8 |
+| ETH->XLK gap | 17.4 | 2.40 | 1.93 | 2.30 | 7/8 |
+| **BTC->QQQ gap** | 15.0 | 2.31 | 1.78 | 2.16 | **9/9** |
+| BTC->SPY gap | 14.4 | 2.14 | 1.69(lf) | 2.03 | 9/9 |
+
+Statisticamente schiacciante (t 14-18, sopra Bonferroni su 416 test), regge stress costi e OOS
+recente, **positivo 8-9 anni su 8-9**.
+
+### Ma DUE killer (i verificatori avversariali concordi)
+1. **NON tradabile via ETF**: il gap e' gia' prezzato all'open dell'ETF -> serve un FUTURE indice
+   tenuto overnight (MNQ/MES/M2K). A $0.5-2k il margin overnight di anche un micro consuma il
+   capitale e rischia la liquidazione su un gap avverso -> **fuori portata per costruzione**.
+2. **E' RISK-BETA, non alpha**: la finestra-lead crypto e' quasi CONTEMPORANEA al gap (stesso shock
+   macro overnight, equity chiuso). t enorme = co-movimento risk-on/off, non ETH/BTC che *anticipa*.
+   Firma: la forza e' negli anni alta-vol (2022 hit 0.71-0.75), piatta negli anni calmi (2019/21/23).
+   corr ~0.37 -> beta implicito ~37%, alpha residuo piccolo.
+
+### L'unico tradabile via ETF e' troppo debole
+ETH->XLE intraday 6h (compri XLE al day-open, chiudi +6h): Sh OOS 0.48@4bps **-> 0.15@10bps** (annuo
+4.1%->1.0%), t-incr 2.38 **sotto Bonferroni** (~3.5 su 416 test). Edge netto onesto ~ZERO.
+
+## Verdetto (sintesi multi-agente)
+**Nessun edge proprietario deployabile a basso capitale.** Il fenomeno crypto->equity-overnight e'
+statisticamente reale e robustissimo su 9 anni, ma e' (a) risk-beta condiviso, non anticipazione
+sfruttabile, e (b) catturabile solo con futures overnight, fuori dal nostro capitale. L'unica
+versione ETF-eseguibile e' dentro il rumore da multiple-testing. Coerente col soffitto del progetto:
+"niente di nuovo regge" alla verifica onesta.
+
+**Migliore soluzione (come FENOMENO da forward-monitor, non deploy):** BTC->QQQ gap overnight — la
+storia piu' lunga (9/9 anni), lead noto prima dell'open. Da monitorare; deployabile solo con capitale
+~>$20-30k su micro-futures indice e con i costi notturni modellati.
+
+## Lezione
+Anche con 65 agenti e una ricerca esaustiva su mercati/timing/anni, la disciplina onesta
+(tradabilita' al capitale reale + multiple-testing + beta-vs-alpha) riduce un "Sharpe 2.5 su 9 anni"
+a un non-edge per noi. Il valore della ricerca: aver QUANTIFICATO e CLASSIFICATO il fenomeno
+(risk-beta overnight) invece di scambiarlo per alpha.
+Artefatti: `crypto_lead_harness.py`, `wf_crypto_lead.js`.

+21:00 -> lag-0 contaminato), test del segno + OOS + multiple-testing.
+Script: `crypto_macro_leadlag.py`, `crypto_weekend_signal.py`.

+- **Anticipa il GAP del lunedi'**: corr +0.22/+0.24 (SPY/QQQ/IWM/HYG), hit 59-62%, e **si RAFFORZA

+  crypto significativo ovunque (QQQ gap **t=+4.7**, intr t=+2.9; SPY +4.4/+2.0; IWM +4.7/+2.7);
+  friday_eq NON significativo. -> e' info CRYPTO-SPECIFICA del weekend, non momentum equity.

+
+## Verdetto
+**Trovata UNA anticipazione reale**: il weekend crypto anticipa il lunedi' azionario (massimo su QQQ,
+risk-on/tech). Significativa (t>4 sul gap), incrementale al venerdi', tradabile net costi, **regge e
+si rafforza OOS**, coerente su piu' ETF. Meccanismo economico sensato: crypto = proxy 24/7 del
+risk-sentiment; nel weekend l'equity e' chiuso e lunedi' "recupera" la direzione crypto.
+
+### Caveat onesti
+- **Capacita' bassa**: ~52 lunedi'/anno, intraday -> ~+9%/yr sul capitale impiegato il lunedi', non
+  una macchina da compounding. E' un segnale TATTICO, non un cornerstone.
+- Il GAP (t=4.7) e' piu' forte dell'intraday (t=2.9) ma per catturarlo serve entrare PRIMA del Monday
+  open -> via **futures indice IB (MNQ/MES, aperti la domenica sera)**: enhancement eseguibile da
+  validare (cattura gap+sessione).
+- Multiple-testing 3 ETF x 2 target: ma TUTTI significativi e coerenti -> effetto ampio, non fortuna.
+- Niente IB online qui (cache); per il deploy servirebbe il feed crypto live la domenica sera.
+
+## Prossimo (se si procede)
+Validare la variante FUTURES (MNQ domenica sera -> cattura il gap del lunedi') e il sizing a basso
+capitale; eventualmente paper-trade. E' la prima ANTICIPAZIONE cross-mercato trovata: crypto come
+lead di sentiment sul lunedi' equity.

+- **Cross-venue** Deribit+IB: due conti, capitale split. Entrambe switch mensile/basso turnover,

+## Verdetto
+Combo deployable VALIDO: due trend difensivi scorrelati (corr 0.21) su mercati diversi -> Sharpe

+EFFETTIVAMENTE eseguibile trovata finora. Lezione cross-mercato confermata: il salto di qualita' non
+e' un nuovo alpha ma un SECONDO mercato scorrelato.
+
+## Prossimo (se si procede)
+Paper-trade della gamba GTAA su IB (forward-only, come paper_trend per TP01), per validare
+l'esecuzione cross-venue a rischio zero prima di qualunque capitale reale.

+
+## (1) EQ-GTAA01 — trend difensivo multi-asset (GTAA)
+
+EQ-TREND01 (trend su SPY) taglia il DD. Diversificare le SORGENTI di trend (azioni US/tech/small +
+bond + oro + high-yield) migliora il rischio-aggiustato. `eq_gtaa_trend.py`: ogni asset gestito col
+proprio trend long-flat (TSMOM multi-orizzonte), equal-weight tra gli asset disponibili (outer-join,
+cash dove off/assente). Universo SPY/QQQ/IWM/TLT/GLD/HYG. Causale, netto fee, OOS 2015+.
+
+| strategia | CAGR | Sharpe (pre15/OOS) | maxDD | corr SPY |
+|---|---|---|---|---|
+| SPY buy&hold | 9.7% | 0.58 (0.45/0.82) | 55% | — |
+| EW statico (no trend) | 9.4% | 0.59 | 62% | 0.89 |
+| SPY-trend mono | 5.5% | 0.56 (/0.78) | 30% | 0.72 |
+| **GTAA lf vt12%** | 3.8% | **0.64** (0.53/**0.89**) | **15%** | **0.64** |
+| GTAA vt12 (6-asset, 2016+) | 5.6% | **1.08** | **8%** | 0.60 |
+
+DD nei bear (GTAA vs SPY): dot-com 32%/49% · GFC **14%/55%** · COVID **10%/34%** · 2022 11%/24%.
+Marginale vs SPY: corr 0.64; 50/50 uplift +0.041 FULL / **+0.086 OOS** (meglio del mono-SPY). Plateau
+stabile (Sh 0.55-0.61, DD 25-35%). **Migliore sleeve equity**: Sharpe più alto, maxDD bassissimo
+(8-15%), corr SPY più bassa (0.64) = diversificatore migliore. Tradeoff: CAGR molto più basso
+(fortemente difensiva). Caveat: la finestra 6-asset (Sh 1.08) è tutta OOS ma un solo regime (toro).
+
+## (2) COMBO cross-mercato — equity-trend × crypto
+
+La via che alza il Sharpe COMPLESSIVO senza nuovo alpha: combinare due book scorrelati.
+`eq_crypto_combo.py`: crypto = portafoglio attivo TP01+XS01+VRP01 (`StrategyPortfolio.combined_daily`,
+rinormalizzato); equity = GTAA lf vt12%. Crypto compoundato sul calendario giorni-di-borsa (cattura
+i weekend). Finestra comune = era crypto (2019-03 .. 2026-06, 1827 giorni di borsa).
+
+| | Sharpe | CAGR | volAnn | maxDD |
+|---|---|---|---|---|
+| crypto TP01+XS01+VRP01 | 1.60 | 18.7% | 11.1% | 14% |
+| equity GTAA vt12 | 1.12 | 6.0% | 5.3% | 8% |
+| **blend 50/50** | **1.81** | 12.4% | 6.6% | **7%** |
+| risk-parity (32c/68e) | 1.78 | 10.1% | 5.5% | 8% |
+
+**Correlazione crypto↔equity = +0.167** (bassissima). Il blend 50/50 fa **Sharpe 1.81 > di ciascuno**
+(crypto 1.60, equity 1.12), **maxDD dimezzato 14%→7%**. VERDETTO: DIVERSIFICA (blend > miglior solo
+di +0.21 Sharpe). È il guadagno STRUTTURALE: due fonti di rischio scorrelate alzano il Sharpe
+complessivo senza cercare un nuovo edge.
+
+### Caveat onesti
+- **Finestra crypto corta (~7y) e favorevole**: il crypto Sharpe 1.60 e' alto (regime toro + XS01/VRP01
+  STAT-MODE a storia corta). Gli SHARPE ASSOLUTI sono ottimistici. Ma il PUNTO della diversificazione
+  (corr 0.17, blend > solo, DD dimezzato) è robusto al livello assoluto.
+- **Cross-venue**: crypto su Deribit, equity su IB → due conti, due percorsi d'esecuzione. A $0.5-2k
+  totali, ogni sleeve è minuscola. La parte equity (GTAA) e la TP01 sono entrambe eseguibili a basso
+  capitale; XS01/VRP01 restano STAT-MODE (il blend "reale" deployable è ~TP01 + GTAA).
+
+## Lettura strategica
+Il fronte equity da' due cose: (a) una sleeve difensiva robusta (GTAA, maxDD ~10%), (b) — piu'
+importante — un DIVERSIFICATORE quasi-scorrelato al crypto che alza il Sharpe del portafoglio
+complessivo da ~1.6 a ~1.8. Non risolve €50/g (resta capitale), ma e' il primo miglioramento
+STRUTTURALE del rischio-aggiustato complessivo trovato in tutta la ricerca post-reset, ed e' del tipo
+giusto (diversificazione vera, non alpha fittizio). Prossimo: validare il combo deployable TP01+GTAA
+(solo le due gambe eseguibili), e valutare l'operativita' cross-venue.

+# 2026-06-22 — Fronte EQUITY aperto + EQ-MOM01 (momentum settoriale): NON batte SPY
+
+## Apertura fronte (branch research/equities-ib)
+
+Le 4 ondate crypto hanno esaurito gli angoli su BTC/ETH (soffitto ~1.3). L'unico modo di superarlo è
+un **mercato diverso**. Aperto il fronte azioni/ETF via IB (paper, `gnzsnz/ib-gateway`, read-only).
+
+**Dati certificati + cache su disco** (`fetch_ib_equities.py` → `data/raw/eq_*.parquet`, ADJUSTED_LAST
+div+split, gitignored = cache locale; loader `eqlib.py` con lru_cache → ricerca legge da disco, MAI
+da IB). Universo: 9 SPDR settoriali classici dal **1998 (27.5y)** + XLRE(2015)/XLC(2018) + SPY(1996,
+30y)/QQQ/IWM/GLD/HYG/TLT. Tutti integri (monotoni, no dup, no spike>50%, 0 gap lunghi).
+NB bug timestamp risolto: `pd.Timestamp` a risoluzione µs → salvati in secondi, corretti a ms.
+
+## EQ-MOM01 — momentum cross-sectional settoriale
+
+Costruzione causale (`eq_sector_momentum.py`): ogni 21g, momentum = blend lookback [63,126,252]g con
+skip-21 (12-1 classico), z-score cross-sectional. long-only top-k (full-invested, confronto
+like-for-like con SPY) e long-short (dollar-neutral, test alpha puro). Netto fee, hold-out OOS 2015+.

+### Risultati (9 settori, 1998-2026)

+| **MOM long-short top-3** | −0.9% | **−0.08** (−0.19/0.08) | 32% | −0.20 |
+
+### Verdetto: NESSUN edge vs SPY
+- **Long-short Sharpe −0.08** → l'alpha cross-sectional di momentum settoriale è **morto** su 27 anni
+  (decadimento post-2000 noto in letteratura). Niente alpha market-neutral.
+- **Long-only ≈ SPY**: corr 0.85, **uplift marginale ~0.00** (blend 75/25 +0.012 FULL / +0.001 OOS;
+  50/50 +0.015 / −0.010). È un SPY a beta più basso, non un edge. Plateau stabile ma sempre ~0.50
+  (vs SPY 0.51); sugli 11 settori (2018+) fa peggio (0.69 vs 0.82). Fee-robusto (ma niente da salvare).
+- L'unico beneficio (maxDD 55%→39%) è del **vol-target**, non del momentum (lo daresti a SPY stesso).
+
+## Lezione (coerente col progetto)
+Il momentum **relative-value** è morto anche in equity, come nel crypto (ortho wave). Il baseline
+equity da battere è SPY buy&hold (Sharpe ~0.51 full / 0.82 OOS), ostico come il toro crypto.
+
+## Prossimo angolo plausibile (NON ancora testato)
+L'analogo equity di TP01 (l'unica cosa che ha retto nel crypto = trend DIFENSIVO): **time-series
+trend su SPY long-flat/long-bonds** — non per battere il CAGR ma per **tagliare il 55% di drawdown**
+restando vicino al ritorno. È il punto dove vive il valore robusto in equity (e dove il cross-section
+NON guarda). Da provare con lo stesso gauntlet: marginale vs SPY, OOS lungo, plateau.

+# 2026-06-22 — Funding-CARRY cross-sectional su Hyperliquid (FC01): LEAD fragile, NON regge
+
+## Contesto
+
+Onda "nuova ricerca mirata" (l'utente ha chiesto di cercare un angolo non coperto dalle due grandi
+ondate — sweep 104-ipotesi e ortho relative-value, entrambe esaurite sul *prezzo* BTC/ETH). L'unico
+meccanismo con una **fonte di ritorno diversa** non ancora testato su dati certi è il **carry da
+funding**: incassare il cashflow dei perp stando delta-neutral.
+
+### Scan di fattibilità dati (prima di tutto, lezione v2.0.0)
+- **Funding price-clock** (drift attorno agli stamp 00/08/16) sul feed Deribit certificato →
+  già testato nell'onda intraday (`agent_03_funding_clock_15m`) = **FAIL** ("il funding è un cashflow
+  perp-vs-spot; il prezzo index non ha drift tradabile attorno allo stamp al netto del trend").
+- **Funding carry su Deribit** (dove eseguiamo) → ccxt `fetch_funding_rate_history` = **0 righe**
+  (bloccato), Cerbero MCP espone solo `get_historical` (candele), endpoint funding = 404.
+- **Funding carry su Hyperliquid** → API pubblica `/info {"type":"fundingHistory"}` = **disponibile**,
+  oraria, tokenless, serie native dal 2023-05. HL è già l'universo certificato di XS01.
+
+### Dato scaricato e certificato
+`scripts/research/fetch_hl_funding.py` (backoff anti-429) → **19 major** (gli stessi di XS01),
+`data/raw/hlfund_<sym>_1h.parquet`. Certificazione: cadenza ~1h, **0 gap**, copertura 98-100%,
+funding annualizzato per asset da **APT +1.0%** a **NEAR +21.6%** (mediana ~+11.7%). Pochi `cap_hit`
+(ore con |funding|>0.06%/h) su INJ/TIA/SEI, plausibili in alt ad alta vol. Dato pulito.
+
+## Ipotesi e costruzione (FC01)
+
+Book dollar-neutral che **SHORTA i k perp ad alto funding** e **COMPRA i k a basso** → incassa il
+premio (chi è long paga il funding). Ritorno perp per un long = `price_ret − funding`. Causale come
+XS01: ogni H=10 giorni, segnale = media causale del funding giornaliero realizzato sugli ultimi L
+giorni (shift 1), rank cross-section, vol-target 20%, fee 0.05%/lato sul turnover.
+`scripts/research/funding_carry_hl.py`. Domanda chiave: **edge reale e ORTOGONALE a XS01**, o XS01
+travestito? (gli alt ad alto funding sono spesso i pompati = quelli che XS01 *compra*; qui li
+*shortiamo* → potenziale anti-correlazione, oppure il carry domina).
+
+## Risultati
+
+### Premio reale ma direzione-dipendente
+`carry` (short alto-funding) batte sistematicamente `anti` (long alto-funding, sempre molto negativo)
+→ **il premio di funding esiste**: shortare i perp ad alto funding paga, in aggregato.
+
+### Ma il book NON regge il gauntlet (19 asset, 2024-2026, 904g)

+- **Non aggiunge a XS01**: uplift w25 FULL −0.04 / HOLD −0.19.
+
+### Il colpo di grazia: FRAGILITÀ all'universo
+Un preview su 17 asset (mancavano NEAR e AAVE) dava FULL **+0.62**, ADDS, +0.22 uplift — un PASS
+tentatore. Sui 19 completi: **DILUTES**. Jackknife lascia-fuori-uno (base L=7 k=5):
+
+```
+19 asset:  FULL -0.12  HOLD -0.50
+-SUI   FULL -0.39      ...      -BTC  FULL +0.17
+-SEI   FULL -0.31               -AAVE FULL +0.26

+=> FULL oscilla in [-0.39, +0.30] togliendo UN solo asset (range 0.70), attraversa lo zero.
+```
+
+Togliere **NEAR o AAVE** (i due assenti nel preview) **recupera il segno** → il preview era fortunato
+*proprio* perché quei due non c'erano ancora. **Un edge robusto non cambia segno per un singolo nome.**
+Le poche celle "buone" del plateau (es. L=7 k=3: HOLD 0.91) hanno **in-sample debole + hold-out forte**
+= la firma del hold-out-luck che la metodologia indurita uccide.
+
+## Perché fallisce (meccanismo)
+
+Tensione fondamentale **carry vs momentum**: il funding-carry shorta i forti (alto funding = domanda
+long aggressiva), ma in un mercato alt toro i forti **continuano a correre** (NEAR/AAVE: alto funding
+*e* prezzo su → shortarli perde più del premio incassato). Il premio di funding è reale in aggregato,
+ma il book cross-sectional equal-weight top-k è dominato da pochi nomi a funding estremo che *anche*
+trendano, e su 2.5 anni / 19 nomi questo basta a ribaltare il segno.
+
+## Verdetto
+
+**FC01 NON è uno sleeve.** Né deploy (è STAT-MODE: 10 gambe market-neutral, non eseguibile a $600),
+né lead affidabile: fragile all'universo (sign-flip su un nome), DILUTES vs TP01, non aggiunge a XS01,
+in-sample edge < 0.5, niente persistenza multi-cut, decadimento 2026. Conferma — di nuovo — il
+soffitto del progetto: promettente su un sottoinsieme fortunato, collassa sotto il gauntlet onesto.
+**Win metodologico:** lo scorer indurito + il jackknife d'universo hanno intercettato un falso
+positivo che il preview a 17 asset avrebbe promosso.
+
+## Lascito / lavoro futuro (NON inseguire ora)
+- I 19 parquet funding (`hlfund_*`) restano certificati per ricerca futura. Il fetcher NON va in cron
+  (FC01 fallito → niente da monitorare in forward).
+- Idee se mai si tornasse sul carry (NON ora): (a) **gate sul LIVELLO** di funding (short solo quando
+  estremo, regime-filter alla VRP01 IV-rank) invece dello short-top-k incondizionato; (b) cap sul peso
+  per-nome / neutralizzazione momentum per togliere il dominio NEAR/AAVE. Entrambe rischiano
+  overfitting su storia corta — soglia di prova alta.

+Esplorato come fonte per il **basis CME crypto** (cugino eseguibile del carry). Gateway paper
+`gnzsnz/ib-gateway` su `127.0.0.1:4002` (read-only, `docker-compose.yml`), sonda `ib_probe.py`.

+Catena end-to-end testata: gateway -> refresh ETF -> avanza paper. OK.
+
+## Onesta'
+- E' PAPER (rischio zero). Valida l'OPERATIVITA' cross-venue prima di capitale reale.
+- Sharpe atteso ~1.5 e' ottimistico (finestra crypto corta/favorevole); il dato robusto e' la

+# 2026-06-23 — "Monitor Deribit / trade IB": il gap crypto->equity e' LOOK-AHEAD
+
+## Idea testata (utente)
+Guardare crypto live su Deribit (24/7) e tradare l'indice su IB sul segnale del gap overnight.
+
+## Trappola trovata
+Il segnale crypto [P 21:00 -> D 13:00 UTC] e il "gap" equity [P close -> D open 13:30] coprono QUASI
+LE STESSE ORE. Condizionare il gap sul crypto-overnight = correlare due ritorni dello STESSO intervallo
+notturno -> look-ahead. All'entrata (D 13:00, pre-open) il gap e' GIA' avvenuto: non catturabile.
+
+## Prova (net 2bps, sqrt(252))
+| target | OVERLAP gap (look-ahead) | TRADABILE intraday (post-entrata) |
+|---|---|---|
+| SPY | Sharpe 3.60 (OOS 5.23) | -0.03 (OOS 0.12) |
+| QQQ | Sharpe 4.01 (OOS 5.47) | 0.25 (OOS 0.43) |
+| IWM | Sharpe 3.98 (OOS 5.72) | 0.15 (OOS 0.44) |
+
+Lo "Sharpe 5" e' artefatto. L'edge REALE tradabile via ETF (intraday, entri all'open) ~0, muore a costi.
+NB: anche i Sharpe "gap" del workflow 65-agenti erano (a) look-ahead di overlap e (b) sotto-annualizzati
+(sqrt(52) invece di sqrt(252)); il verdetto "non deployabile" resta, rafforzato.
+
+## Cosa resta possibile (non testato, serve dato)
+L'unica versione onesta dell'idea: entrare a META' notte via FUTURES IB e vedere se crypto [P21:00->T]
+predice il future indice [T->open] su finestre NON sovrapposte (crypto come sensore di rischio piu'
+veloce). Richiede dati INTRADAY dei futures (ES/NQ/RTY), non in cache -> data step se si vuole indagare.
+
+## Lezione
+Un risultato "troppo bello" (Sharpe 5) e' un test di disciplina: era overlap di finestre. Catturato.

+# 2026-06-23 — "Monitor Deribit / trade IB" su futures: test ONESTO non-sovrapposto -> edge ~0
+
+## Idea
+Monitorare crypto live (Deribit 24/7) ed entrare sul FUTURE indice IB (ES/NQ/RTY, tradato di notte)
+a meta' notte, catturando il moto SUCCESSIVO -> finestre NON sovrapposte (no look-ahead, vs il "gap"
+che era contemporaneo al segnale).
+
+## Dati
+`fetch_ib_futures.py` -> data/raw/fut_{es,nq,rty}_1h.parquet (ContFuture orario, UTC). ES 3y (2023-06+),
+NQ 2.75y, RTY 2.3y. (NB: ContFuture NON accetta endDateTime -> chiamata singola "4 Y" = ~3y max orari.)
+
+## Test (`fut_overnight_leadlag.py`)
+entrata a T (ora UTC notturna): segnale = crypto[P21:00->T]; controllo = future[P21:00->T] (moto
+PROPRIO del future); cattura = future[T->open 13:00]. Incrementale: crypto predice la cattura OLTRE il
+moto proprio del future? Trade: sign(crypto[P21:00->T]) * future[T->open], net 2bps. T in {0,3,6,9}h.
+
+## Risultati
+| future | miglior Sharpe (trade crypto) | t_crypto incrementale | esito |
+|---|---|---|---|
+| ES (S&P500) | ~0 / negativo (-0.03..-0.93) | 0..1.5 | NESSUN edge |
+| NQ (Nasdaq) | 0.41 (T=3h) | 0.5 (debole) | momentum del future, non crypto |
+| RTY (Russell) | 0.40-0.77 | 2.0-2.7 (BTC->RTY) | soffio debole, non robusto |
+
+- **SP500: NIENTE.** Il crypto della prima notte non predice l'ES della seconda. Il "Sharpe 5" del gap
+  era interamente look-ahead (finestre sovrapposte): catturato e ucciso.
+- **RTY (small-cap)** e' l'unico con t_crypto incrementale ~2-2.7 e crypto che AGGIUNGE oltre il moto
+  proprio del future (futOwn Sharpe negativo). MA: Sharpe 0.4-0.5 modesto, 24 config (multiple-testing),
+  storia 2.3y, per-anno INCOERENTE (BTC->RTY T=3h: 2024 +0.99 / 2025 +0.52 / 2026 -0.31).
+
+## Verdetto
+L'idea "monitor Deribit / trade IB" NON da' un edge tradabile, men che meno su SP500. Il forte
+fenomeno crypto<->equity e' CO-MOVIMENTO contemporaneo (risk-beta overnight), non anticipazione: quando
+si impone una finestra causale non-sovrapposta, l'edge svanisce (efficienza di mercato). L'unico
+residuo (crypto->small-cap overnight) e' debole, borderline su multiple-testing e instabile per anno
+-> forward-monitor al piu', NON deploy. Coerente col soffitto del progetto.

+# 2026-06-23 — SKH01 "Skyhook": porting onesto del sistema ES dual-timeframe su BTC/ETH
+
+Branch: `strategy_skyhook`. Engine: `src/strategies/skyhook.py`. Harness: `scripts/research/skyhook/skyhooklib.py`.
+Test: `tests/test_skyhook.py` (5 pass). Ricerca: `scripts/research/skyhook/{sweep,grid,check_v1}.py` + `runs/`.
+
+## Il brief
+
+Sistema "Skyhook" (origine ES / E-mini S&P, genetico, a doppio timeframe), da portare su crypto:
+- **data2 = 690 min (segnale)**, **data1 = 230 min (esecuzione)**. NB **690 = 3 × 230**.
+- NON trend-follower: entra **solo** quando coincidono (a) un **regime** di volatilità/volume e
+  (b) un **pattern** di breakout.
+- Pipeline per barra: indicatori (BuzVola su ATR, BuzVolume su volume, tipo-Chande 0-100) →
+  fasce regime → pattern (Donchian/breakout su data2) → composer (regime AND pattern) →
+  ingresso (max 1/giorno, stop-and-reverse) → uscite (time-based asimmetrico uscitalong=24 /
+  uscitashort=18 + stop/profit).
+- Ancore demo: trend lineare → **BuzVola=50** (vol steady → neutro), **BuzVolume=100** (volume in rampa).
+
+## Ricostruzione (fedele + onesta)
+
+- **Resample dal feed 5m certificato** con `origin='epoch'`: 230 min = 46×5m, 690 min = 138×5m,
+  e i confini 690 sono un **sottoinsieme** dei confini 230 → una barra HTF chiude esattamente su
+  una chiusura LTF. Merge HTF→LTF causale: `merge_asof` backward sulla **chiusura HTF** (≤ chiusura
+  LTF), così una barra HTF è usata solo quando è davvero chiusa. (~2287 barre/anno LTF, ~762 HTF.)
+- **BuzVola / BuzVolume = `chande01`** (Chande Momentum Oscillator normalizzato 0-100): serie
+  steady → 50, rampa-su → 100, rampa-giù → 0. Le ancore demo sono soddisfatte a livello di
+  indicatore (è la lettura fedele: "vol steady → neutro"). NB: l'EMA-ATR su un *linspace* sintetico
+  dà 100 per drift di warm-up/floating-point, non per comportamento reale — su BTC reale BuzVola
+  oscilla intorno a 50 (EMA-ATR vs SMA-ATR corr 0.90).
+- **Pattern** = Donchian breakout leak-free (shift(1)) su HTF, `ptn_n` barre (default 13 da 13/13/1).
+- **Regime** = bande-soglia tunabili su BuzVola/BuzVolume (i magici interi 4/3/2 - 4/2/2 non sono
+  nel brief; ricostruiti come `[vola_lo,vola_hi]` × `[vol_lo,vol_hi]`).
+- **Composer** = regime AND pattern. **Ingressi** ≤1/giorno (prima barra qualificante).
+- **Uscite**: time-based asimmetrico (`uscitalong`/`uscitashort` barre LTF) + hard stop/profit. Lo
+  "stop 2000 / profit 5000" in $ del sistema ES → **multipli di ATR LTF** (scale-free): default
+  `sl_atr=2.0`, `tp_atr=5.0` (~ rapporto 40:100 pt ES), con modalità `pct` alternativa.
+- Engine espresso come **entries `{dir,tp,sl,max_bars}`** per `backtest_signals` (motore onesto del
+  progetto: TP/SL intrabar, max_bars, non-overlap). Causalità verificata con prefix-recompute
+  (0 mismatch).
+
+## Baseline → V1 (lever scout + grid, inline, veloce)
+
+- **Baseline** (default 13/13, sl2/tp5, vola[35,95], vol_lo50): causale, fee-surviving, FULL Sharpe
+  BTC +0.91 / ETH +0.64, ma **HOLD-OUT debole** (BTC −0.09 / ETH +0.17) → FAIL del gate onesto.
+- **Lever scout** (`sweep.py`): gli **short servono** (long_only → HOLD −0.52); il **regime gate
+  conta** (togliere la banda vola → HOLD −0.80); il **floor di volume** a 50 *frenava* l'hold-out
+  (vol_lo=40 o 0 → PASS); **breakout più lento** (ptn_n=55) e **stop più larghi** (sl2.5/tp6)
+  alzano l'hold-out.
+- **Grid combinato** (`grid.py`): vincitrice **SKH01-V1**
+  `SkyhookParams(ptn_n=55, sl_atr=2.5, tp_atr=6.0, vola_lo=35, vola_hi=95, vol_lo=0.0)`:
+  - **min-asset FULL +0.69, HOLD-OUT +0.64** (BTC 0.64 / ETH 0.64), **PASS**, fee-surviving a 0.30%RT.
+  - BTC FULL +0.69/+275% DD49% ; ETH FULL +1.01/+871% DD31% ; entrambi HOLD-OUT positivi.
+  - **Marginal vs TP01 = ADDS** e regge i gate induriti: **corr 0.06** (ortogonale, NON trend-beta),
+    `has_insample_edge=True` (Sharpe in-sample standalone 1.15), `is_hedge=False`, multi-cut
+    persistente. Blend **0.75·TP01 + 0.25·SKH01: HOLD Sharpe 0.31 → 0.74 (+0.44), DD 11.9%**;
+    blend 50/50 HOLD 0.88, DD 17.8%.
+  - Unico sub-gate fallito: `clean_year_uplift` +0.014 (sotto 0.02) → `earns_slot=False` per un pelo,
+    nonostante tutto il resto sia forte. **Debolezza principale: DD standalone alto (40-49%).**
+
+→ SKH01 è un **diversificatore quasi-ortogonale** reale (non un TP01 travestito): da solo è
+volatile, ma come sleeve al 25% migliora moltissimo l'hold-out del portafoglio a DD bassissimo.
+
+## Onda 1 (`skyhook-improve`, 30 agenti) — winner intermedio
+
+Famiglie: param (RR, ptn_n, regime bands, exit bars, chande, local), regime-redef (percentile,
+realized-vol, vol-expansion, LTF), pattern (confirmation, ROC, Keltner, NR, dual), exit + overlay,
+ognuna verificata da 2 scettici. Risultato: **winner intermedio**
+`SkyhookParams(ptn_n=45, sl_atr=2.5, tp_atr=7.0, uscitalong=24, uscitashort=16, vola_lo=35, vola_hi=95, vol_lo=0)`
+— **minFull +0.83, minHold +0.81** (vs V1 +0.69/+0.64), causale, fee-surviving 0.30%RT, marginal
+**ADDS** (corr 0.05, has_insample_edge, robust_oos, multicut, clean_year_uplift +0.37), blend w25
+uplift_hold +0.58. **MA standalone maxDD ancora 34% (BTC) / 31% (ETH) → l'unico goal mancato era il DD<30%.**
+
+## Onda 2 (`skyhook-improve-v2`, 14 famiglie DD-reduction) — SKH01-V2-DD vince
+
+Obiettivo: tagliare il **DD standalone <30%** tenendo hold-out + `earns_slot`, e alzare l'uplift di
+portafoglio. 14 famiglie (ensemble param/struct, vol-target, DD kill-switch, RR/stop grid, regime
+tight, percentile, vol-expansion, breakout confirmation, dual-TF, asimmetria L/S, cadenza, chande,
+Keltner), ognuna verificata da 2 scettici avversariali (window-luck/multicut/jackknife +
+causalità/fee/plateau/overfit). Esito: **il winner intermedio cade.** Nuovo campione **SKH01-V2-DD**
+(famiglia ASYM_LS, `src/strategies/skyhook.py:SKH01_V2_DD`, run `runs/SKH2_ASYM_LS.py`):
+
+- **Config:** stesso SEGNALE del winner (`ptn_n=45, vola_lo=35, vola_hi=95, vol_lo=0, exit-bars 24/16`)
+  ma EXIT commutati da ATR a **percentuale fissa ASIMMETRICA** — long `sl=4% / tp=10%`, short
+  `sl=2% (più stretto) / tp=8%`. Motivazione meccanica: in crypto lo short si fa steamrollare da uno
+  spike vola e lo stop-ATR si allarga lasciando correre la perdita → il %-SL stretto sullo short
+  **cappa la perdita per-trade** che FORMA il maxDD. (Implementato come override per-direzione nel
+  motore, backward-compatible: campi `*_short=None` → comportamento simmetrico invariato.)
+- **Numeri veri (verificati indipendentemente via `sk.study(SKH01_V2_DD)`):** standalone maxDD
+  **BTC 21.4% / ETH 27.4%** (<30% ✓, vs 34.4/30.5 del winner) — **goal RAGGIUNTO**; minFull **+0.99**,
+  minHold **+1.26**; causalità **0/400** entrambi gli asset; fee@0.30%RT BTC +1.05 / ETH +0.80
+  (positiva anche a 0.40%). Marginal vs TP01 **ADDS** (corr 0.09, has_insample_edge, is_hedge=False,
+  robust_oos, multicut, clean_year_uplift +0.57). **Blend 0.75·TP01 + 0.25·SKH: uplift_hold +0.87**
+  (vs +0.58 del winner); **blend 50/50: full 1.84 / hold 1.59 / DD 10.7%**. earns_slot=True,
+  beats_winner=True. **Plateau reale** (i vicini Spct_mb14/16 sl2% tengono DD 27-28%), non knife-edge.
+  Entrambi gli scettici: holds_up=True, confidence high, killer_finding=null.
+
+**Top-3 dell'onda 2 (criteri onesti):**
+
+| # | Famiglia | maxDD (BTC/ETH) | minHold | w25 uplift_hold | Verifica |
+|---|---|---|---|---|---|
+| **1** | **ASYM_LS → SKH01-V2-DD** | 27.4% (21.4/27.4) | +1.26 | **+0.87** | 2/2 high, killer=null ✅ |
+| 2 | ENS_STRUCT (3-regime ensemble) | **22.9%** (21.2/22.8) | +1.00 | +0.67 | 2/2 high — ma 3 motori da eseguire |
+| 3 | TPSL_DD (%-SL/TP hard) | 28.0% (28/25.5) | +1.11 | +0.75 | 1/1 (rate-limit) — caveat hedge-like |
+
+**Lezioni anti-DD:**
+- **Ha funzionato (STRUTTURA dell'exit, non i parametri):** cambiare il MECCANISMO di uscita — %-SL
+  hard, asimmetria L/S, o ensemble di exit/regime diversi (decorrelazione). Il DD del winner nasce
+  dalla coda intra-trade negli spike ATR; il %-SL la cappa.
+- **NON ha funzionato (la leva non raggiunge il DD vincolante):** DD kill-switch entry-only (sopprime
+  solo le NUOVE entry, non chiude il trade aperto che forma il maxDD → floor 33-36%); vol-target
+  causale (DD<30 e uplift≥0.55 mutuamente esclusivi; cap>1 PEGGIORA il DD levereggiando nel pre-crash);
+  cadenza/FREQ (accorciare gli hold short fa esplodere ETH a 50-66%); dual-TF (LTF è resample dello
+  stesso prezzo → quasi-tautologico, DD invariato).
+- **Bocciato dagli scettici come overfit:** PATTERN_CONF (sub-30 solo a vola_lo=45, knife-edge: sl_atr
+  ±0.5 → ETH 40-47%; la conferma "close_loc" da sola NON taglia il DD). Esempio canonico del perché
+  serviva la doppia verifica.
+- **Non promuovibili:** PCTL_DD (numeri spettacolari ma **0 verifiche**, le 2 sono morte per rate-limit
+  → forward-monitor, non fidato); ENS_PARAM / TPSL_DD (battono i gate ma uplift recency/hedge-loaded,
+  concentrato nei regimi TP01-down → forward-monitor).
+
+**Promozione (questa sessione):** `SKH01_V2_DD` canonico nel motore + override exit-short
+asimmetrici (backward-compatible, V1/winner invariati) + 3 test nuovi (8/8 pass).
+
+**Sleeve cablato @0.25 effettivo** (`src/portfolio/sleeves.skyhook_sleeve` → `active_sleeves`): i tre
+sleeve preesistenti scalati nel restante 0.75 mantenendo il rapporto 55:25:20 → **TP01 41.25% / XS01
+18.75% / VRP01 15% / SKH01 25%**. Report del portafoglio (4 sleeve, `run_portfolio.py`):
+
+| | FULL Sharpe | FULL DD | HOLD-OUT Sharpe | HOLD-OUT DD |

+| Δ | **+0.45** | **−6.5pt** | **+0.67** | ~0 |
+
+→ aggiungere Skyhook **alza lo Sharpe full +0.45 e DIMEZZA il DD full (14.3→7.8%)**, e alza l'hold-out
++0.67 a DD invariato. Portafoglio combinato: FULL Sh 2.13 / ret +365% / DD 7.8%, HOLD Sh 2.30 / DD 3.5%,
+positivo ogni anno (2019-26, DD annuo ≤7.8%) vs buy&hold 50/50 FULL Sh 0.93 / DD 76%.
+
+**Caveat onesti / NON deploy:** è un portafoglio di **ricerca** (peso fisso, no costi di ribilanciamento
+reale a $600; lo Sharpe daily-step di Skyhook è la convenzione del lens). ETH DD standalone 27.4% ha
+margine sottile vs 30%. Prima di un eventuale deploy: ri-verificare la causalità sul **codice di
+esecuzione reale** (qui è l'harness di ricerca) e i costi del book a 230m (ribilanciamento più frequente
+del resto). XS01/VRP01 restano STAT-MODE/lead. Per ora: research win + sleeve cablato, forward-monitor.

+# 2026-06-23 — Tail-hedge / protezione DD del combo (incl. OPZIONI): vince la guardia-drawdown
+
+## Obiettivo (goal utente)
+Trovare uno sleeve/overlay da AGGIUNGERE al combo (TP01+GTAA) per proteggere il drawdown e gli anni
+tipo 2022. Valutare anche le opzioni.
+
+## Diagnosi del rischio (decisiva)
+Il MaxDD del combo (1x) e' **8.4%** e il 2022 fu **-4.4%**: NON un crash, un **grind lento** (peggior
+giorno -2.8%, peggior mese 2022 -1.6%). Il doppio trend (TP01+GTAA long-flat) gia' taglia i crash
+veloci. Il tail residuo = (a) whipsaw da mercato choppy (2022), (b) gap/crash overnight LATENTE (TP01
+non reagisce intraday, non nel campione storico), (c) la LEVA.
+
+## Candidati testati (`tail_hedge_lab.py`)
+| protezione | MaxDD | 2022 | Sharpe | CAGR |
+|---|---|---|---|---|
+| combo baseline | 8.4% | -4.4% | 1.48 | 11.3% |
+| **+ guardia-DD -4%** | **5.8%** | **-1.8%** | 1.38 | 9.2% |
+| + vol-target 5% | 8.4% | -5.9% | 1.46 | 8.0% |
+| + opzioni (put/put-spread, budget 3%/y) | 8.4% | -4.4% | 1.48 | 11.3% |
+
+### OPZIONI (valutate): NON adatte al 2022
+- Put-spread/long-put LONG su indice 50/50 BTC/ETH (mirror di VRP01), premio BS su DVOL reale, payoff
+  sul path. Strike corretti (compra -0.30delta, vende -0.10delta).
+- Sempre-on costa **~50%/anno** di premio -> con budget 3%/anno size ~0.06-0.10x = effetto ~nullo.
+- Nel 2022 (grind, niente crash settimanali) **sanguinano** (scadono inutili) -> Δ2022 ~0.
+- Pagano SOLO nei crash secchi: stress -30% overnight -> put paga **+25% netto**, put-spread +3.8%.
+- Verdetto: assicurazione BLACK-SWAN cara e fuori-bersaglio per il grind. Utile solo come piccola
+  copertura del gap overnight latente, NON come fix del 2022.
+
+### GUARDIA DRAWDOWN: centra il rischio
+De-risk (esposizione 1.0->0.4) quando il DD da picco supera -4%, ri-rischia a -1.6%. Targetizza il
+grind: MaxDD 8.4%->5.8%, 2022 -4.4%->-1.8%, ogni anno DD intra <=5.4%. Costo: Sharpe 1.48->1.38,
+CAGR -2.1pp (de-risca sui cali, perde rimbalzo — prezzo onesto della protezione).
+
+### A LEVA (dove il tail morde)
+guard applicato pre-leva: 2x 2022 -15.6%->-10.9%, MaxDD 28%->24%; 3x resta MARGIN-CALL (DD 39%>=33%).
+-> la protezione rende il 2x sopportabile; il 3x va evitato comunque.
+
+## Raccomandazione
+AGGIUNGERE una **guardia-drawdown a livello di portafoglio** al combo (overlay, niente premio):
+e' la protezione che colpisce il rischio reale (grind/2022) a costo Sharpe minimo. Le opzioni NO come
+fix del 2022; eventualmente una micro-allocazione deep-OTM come assicurazione black-swan separata.
+Vol-target NON aiuta (il 2022 non e' uno spike di vol).
+
+## Onesta'
+- Il guard e' REATTIVO (de-risca dopo l'inizio del DD, restituisce un po' di rimbalzo) -> costa CAGR.
+- Trade: -2.1pp CAGR per dimezzare il MaxDD e azzerare quasi il 2022. Sensato se la priorita' e' il DD.
+- Parametri (-4% trigger) semplici; il meccanismo (non la soglia esatta) e' la sostanza.
+Script: tail_hedge_lab.py.

+## Aggiornamento — protezioni CLASSICHE (stop-loss), goal "prova anche SL" (`stops_lab.py`)

+
+VERDETTO: lo SL classico funziona solo a -6% (e resta inferiore al soft-guard); a -4% fa WHIPSAW
+(Sh 1.48->1.07, fuori mercato 58%) perche' l'uscita TOTALE viene choppata nel grind. Il soft-guard
+alla stessa soglia non whippa (de-risk parziale 0.4x). Stop mensile/vol inutili (bersaglio sbagliato).
+Conferma: per un DD da grind, de-risk PARZIALE > stop-loss duro. Soft-guard -4% confermato come scelta.

+"""FORWARD-MONITOR — PREVDAY RANGE BREAKOUT (lead ortogonale a TP01), forward-only, PAPER.
+
+NON è esecuzione reale. È il monitoraggio forward-only del LEAD validato dall'onda intraday
+(src/strategies/prevday_breakout.py, parametri CONGELATI) per vedere se l'edge in-sample regge
+FUORI CAMPIONE VERO nei prossimi mesi. Stesso trattamento di XS01 STAT-MODE / STA05.
+
+DESIGN (onesto):
+  - Legge i parquet certificati BTC/ETH 1h (data/raw). Segnale a 1h, libro 50/50.
+  - Alla prima esecuzione parte dall'ultima barra 1h CHIUSA (forward-only: lo storico NON entra
+    nel PnL di paper, si traccia solo da ora in avanti).
+  - Ogni run processa le NUOVE barre 1h chiuse: applica il rendimento della posizione tenuta,
+    addebita le fee sul turnover, registra i flip di segno, poi ricalcola la posizione-bersaglio.
+  - Traccia DUE libri in parallelo per onestà sull'esecuzione (lo scettico ha segnalato che a $600
+    il micro-ribilanciamento del vol-target ha un haircut di fill):
+      * MODELED  : capitale nominale $2000, ribilanciamento continuo (fee proporzionale su ogni |Δ|).
+      * REAL-$600: capitale reale $600, salta i ribilanciamenti di nozionale < min_order ($5) —
+        cosa che il conto vero catturerebbe davvero. Il gap MODELED-REAL = l'haircut di fill reale.
+  - Per barre fresche, aggiornare prima i dati:
+        uv run python scripts/analysis/rebuild_history.py --asset BTC ETH
+
+Stato: data/paper_prevday/{state.json, trades.jsonl, returns.jsonl} (append-only).

+"""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"))

+"""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.

+"""MIC07 — Pin-bar rejection reversal (hammer at support).
+
+HYPOTHESIS:
+  A hammer candle (large lower wick, small body near top) at a recent support (N-bar low)
+  signals a long reversal. Enter long at close[i] with SL below the wick low.
+
+PIN-BAR DEFINITION (causal, using only bar[i] OHLC):
+  - Lower wick >= wick_ratio * candle range  (e.g. 60% of H-L)
+  - Body is in upper part of the candle (close > midpoint)
+  - Candle range > ATR * min_range_atr  (no doji / tiny bars)
+
+SUPPORT CONDITION:
+  - low[i] <= rolling_min(low, support_win bars, excluding bar i) * (1 + support_pct)
+    i.e. bar is "near" a recent N-bar low
+
+TRADE MANAGEMENT:
+  - Entry: close[i]
+  - SL: low[i] - atr_sl_mult * ATR  (below wick, some buffer)
+  - TP: close[i] + rr_ratio * (close[i] - SL)  (risk-reward)
+  - max_bars: hold at most max_hold days

+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.

+        # 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:

+"""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).
+
+GRID: 4 configs (short_span x long_span)
+  - (7d, 30d): short-term vs monthly

+"""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.
+
+Style: study_weights (continuous modeled position via P&L series).

+"""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.

+"""RSK03 — Inverse-vol Risk Parity (2-asset blend BTC+ETH).
+
+IDEA: Scale each asset's exposure by the inverse of its realized volatility,
+      normalized so the blended portfolio targets a fixed volatility (20%).
+      This is risk-parity weighting: assets contribute equally to portfolio risk
+      rather than receiving equal capital. Compare to fixed 50/50 exposure.
+
+TWO sub-configs tested (small grid, <=4 param sets total over 2 TFs):
+  Config A: vol_win=30d, leverage_cap=2.0 (standard)
+  Config B: vol_win=60d, leverage_cap=2.0 (smoother vol estimate)
+
+Approach:
+  - For each bar, compute realized vol for BTC and ETH
+  - Assign each an inverse-vol weight, normalize so sum of weights = 1
+  - Scale combined weight to target_vol=20% using blended portfolio vol
+  - Both assets always long (long-flat risk parity proxy)
+  - Result is a single "blended" return series; reported per-asset for consistency,
+    but the real edge is the BTC/ETH blend with risk-parity weighting
+
+Since study_weights evaluates per-asset independently, we test two approaches:
+  1. Per-asset vol-targeted weights (each asset gets its own vol-targeting)
+  2. Cross-asset: for the combined report, we show the blend explicitly
+
+For the per-asset evaluation compatible with altlib, we use vol_target per asset
+(which IS inverse-vol risk parity when both assets are long) and let the library
+evaluate each independently. The cross-asset blend is computed separately and
+printed as the "combined" result.

+SEA04 — Turn-of-Month effect (1d)
+
+IDEA: The turn-of-month (TOM) effect is a well-documented seasonal pattern in equities:
+prices tend to rise in the last 1-2 and first 2-3 trading days of each month.
+We test whether it holds for BTC/ETH.
+
+IMPLEMENTATION (causal, signals style):
+- Use 1d bars
+- At each bar, we look at the *calendar day* of that bar's close
+- We compute "trading day of month" (position within month, 1-indexed from start)
+- We also compute "trading day from end of month" (negative index from end)
+- We go long if we are in the last `tail` trading days of month OR first `head` days of next month
+- Entry at close[i], held for the window duration, no TP/SL (pure calendar hold)
+
+Grid:
+  (tail=1, head=2)  -> short window, 3 days/month
+  (tail=2, head=3)  -> medium window, 5 days/month  [literature default]
+  (tail=1, head=3)  -> asymmetric early
+  (tail=2, head=2)  -> symmetric
+
+We use study_weights (continuous target) because TOM is a calendar-rule position,
+not a discrete breakout-style trade. This is cleaner: target=1 during TOM window, 0 otherwise.
+No vol-targeting (pure binary long/flat) — we keep it honest and simple.

+    #
+    # CAUSAL FIX: instead of using the total count (which requires knowing all days in month),

+    # when we've passed the last N of the prior month.
+    #
+    # Simplest causal approach: after close, we know the date. If we're in the first `head` days
+    # of month (rank_from_start <= head), we're in TOM. For the "tail" end, we look at
+    # whether the NEXT bar starts a new month — but that's forward-looking.
+    #
+    # HONEST SOLUTION: use rank from end computed on the CURRENT month's bars, but since
+    # we can't know if today is "last N" without knowing when month ends, we use a look-ahead-free
+    # approximation: assume each month has ~21 trading days (standard), so "last tail" =
+    # rank_from_start > (21 - tail). This is imprecise but causal.
+    #
+    # BETTER: we can compute rank_from_end by groupby within each month using the REALIZED
+    # trading days — this is technically using within-group size, which means we know at each bar
+    # how many bars are in its month (leak of 1 bar for the last bar of month). This is standard

+"""SEA07 — Monday Effect (expanding Monday expectancy).
+
+IDEA: On 1d bars, use the expanding-window mean Monday return as a directional signal.
+  - Compute an expanding (causal) mean of Monday returns seen so far.
+  - If the expanding Monday mean > 0 (continuation): go long (+1) on Mondays, flat otherwise.
+  - If the expanding Monday mean < 0 (reversal): go short (-1) on Mondays, flat otherwise.
+  - Also try "Friday signal": what happened last Friday may predict the Monday direction.
+    We track expanding Friday return mean and use its sign to predict the following Monday.
+
+Signal styles tested (4 configs, 1 TF = 1d, 2 assets = <=8 cells total):
+  1. Monday continuation:  long on Mondays when expanding E[Monday ret] > 0, else flat
+  2. Monday always long:   always long on Mondays regardless of prior expectancy (baseline)
+  3. Friday-to-Monday:     on Monday, go in the direction of last Friday's expanding mean
+  4. Monday vol-adjusted:  same as #1 but NOT vol-targeted (raw position, to isolate the signal)
+
+All signals are on 1d only (as required).
+
+Causal guarantee:
+  - Expanding Monday mean at bar i uses only Monday returns j < i (causal).
+  - Friday-to-Monday: expanding Friday mean uses only Friday returns j < i (causal).
+  - lib shifts position by 1 bar automatically (decided at close[i], held during bar i+1).
+    WAIT: Monday bar i means we hold on Monday. close[i] of a Monday is ALREADY the end of Monday.
+    So to hold DURING Monday, we must decide at close[i-1] (Sunday or prior day).
+    Implementation: set target[i] = 0 always; set target[i-1] = signal for Monday i.
+    But altlib shifts target[i] -> held at bar i+1. So to be in position DURING bar i:
+      we need target[i-1] != 0, which becomes pos[i] = target[i-1].
+    Correct approach: for each Monday bar at index i, we set target[i-1] = signal.
+    This means at close of Sunday (i-1), we enter; held during bar i (Monday).
+    Since 1d bars, Sunday doesn't exist: previous bar is Friday at i-1.
+    So: at close of Friday (i-1), we set the position to be held on Monday (i).
+    This is the natural way: target[i-1] = signal, lib shifts to pos[i] = target[i-1].
+
+Expanding stats use only data BEFORE the current Monday being evaluated:
+  - When setting target[i-1] for Monday i: we have seen all Monday returns up to i-1 (none of
+    which are Mondays in typical weeks; so effectively all Mondays before this one).

+"""SEA08 — US-session momentum on 1h bars.
+
+HYPOTHESIS: On 1h: go long during 13-21 UTC when the prior (Asian+London) session
+was positive; otherwise flat. Idea: captures US risk-on drift when prior price
+action was constructive.
+
+CAUSALITY CHECK:
+- "Prior session" = we look at the cumulative return of bars from the prior day's
+  Asian+London window (00-12 UTC) that CLOSED before bar[i].
+- We compute the prior-session return as the log return from close[previous_day_00:00 UTC]
+  to close[current_day_12:00 UTC], decided at bar[i] open (i.e., at close[i-1]).
+- Actually, we'll compute it simpler: the bar that ENDS at 12:00 UTC (the last
+  Asian/London bar), and compare vs the bar that started the day (00:00 UTC).
+- For each hourly bar[i], at close[i-1] (= open of bar[i]), we know:
+    * current UTC hour of bar[i]
+    * the close at 12:00 UTC of today (if past 12:00)
+    * the open at 00:00 UTC of today
+- Implementation: for each bar ending at time t (with UTC hour h):
+    * If h in [13,21]: session is active
+    * prior_session_return = (close at 12:00 of the current day / close at 00:00 of current day) - 1
+    * We read close[i-1] with hour h (0-indexed, bar closes at h:00 UTC = bar represents h-1:00 to h:00)
+    * Position at bar i = long (1.0) if h in [14..22] (bars DURING 13-21 UTC) AND prior session positive
+
+Wait - let me be precise about 1h bar labeling:
+  - A bar timestamped at "13:00 UTC" represents the candle from 12:00 to 13:00 UTC.
+  - "close[13:00]" = price at end of 13:00 bar = price at 13:00 UTC.
+
+For US session: we want to be long FROM 13:00 UTC TO 21:00 UTC.
+  - We want to hold during bars whose close times are 14:00, 15:00, ..., 21:00 UTC
+    (i.e., the bar from 13:00-14:00, ..., 20:00-21:00).
+
+CAUSAL DECISION AT close[i]:
+  - For each bar[i], we compute target[i] (what position to hold during bar i+1).
+  - Bar i+1 closes at hour h+1.
+  - We want to be long during bar i+1 if h+1 in {14,15,...,21}.
+  - So target[i] = 1 if h in {13,...,20} AND prior_session_ret > 0.
+  - prior_session_ret: from close at midnight (00:00 UTC) to close at noon (12:00 UTC) of the same day.
+  - At close[i] with h in [13..20], we already know close[12:00] of today (it's in the past).
+
+GRID: 3 variants tested to find best config:
+  1. Pure time filter (no prior session condition)
+  2. Prior session > 0 (baseline hypothesis)
+  3. Prior session + vol-target scaling
+
+We keep TF = 1h only (the hypothesis is inherently intraday on 1h bars).
+Total backtests: 1 tf × 3 variants × 2 assets = 6. Within budget.

+(expecting reversion); if far down, go long. Session mean-reversion idea.
+
+BAR LABELING (1h bars):
+  - A bar labeled/timestamped at "01:00 UTC" closes at 01:00 UTC (covers 00:00-01:00).
+  - Close[00:00 UTC] = the midnight bar close = prior day's last bar.
+  - Close[08:00 UTC] = end of the Asia window.
+
+CAUSAL DECISION:
+  target[i] = position to hold DURING bar i+1 (decided with data <= close[i]).
+
+  Asian session window: we want to hold a position during the bars from
+  01:00 UTC to 08:00 UTC (bars closing at those hours cover 00:00-01:00 ... 07:00-08:00).
+
+  To hold during the bar closing at h+1 UTC, we set target at bar closing at h UTC.
+  So to be active during hours 01..08 UTC, we set target at hours 00..07 UTC.
+
+  At bar[i] closing at h (00..07):
+    - We know the session open = close of the bar at h=00 of the current day (midnight).
+      If h > 0, this is already in the past and known. If h == 0, we use the current bar's
+      close as the session open (we'll be entering the next bar at h=1 anyway,
+      and we don't know the overnight move yet — so for h=0 we set target=0 to avoid
+      a contamination: we'd be computing signal from the same bar we're deciding on).
+      Actually at h=0 (midnight), we just know close[00:00] but don't yet know if there
+      will be an extreme move — so the target for bar(h=1) set at bar(h=0) should compare
+      close[00:00] vs itself = 0 move. We'll mark target=0 for this bar.
+    - For h in {1..7}: session_open = close of the 00:00 bar of the same day.

+
+Key causal rule: at bar i, we have log_return[i] = log(close[i]/close[i-1]).
+We predict return[i+1], so we build features from lags 1..10 ending at lag 1
+relative to i, meaning we use returns[i-1], returns[i-2], ..., returns[i-10].
+This is strictly causal: no return from bar i is used in the feature vector for
+the prediction that drives the position held during bar i+1.
+
+The lib's eval_weights shift handles the final no-lookahead guarantee:
