Adriano Dal Pastro 82c05f6f81 fix(exec): code-review serale — guard anti-posizione-nuda sul netting + verità per-frazione
7 finder paralleli sul diff della giornata (8adf388..HEAD), fix dei confermati:

CRITICI (money-path):
- close_amount: GUARD stato-stantio sul fallback netting — il residuo
  non-reduce-only e' consentito solo fino al gap (conto reale - libri degli
  altri worker - orfani) nella direzione della chiusura (src/live/books.py =
  fonte unica, usata anche dal reconciler). Senza guard, un close su stato
  stantio (DSL scattato in outage, flatten manuale) APRIVA una posizione nuda
  a taglia piena bookata come 'chiusura verificata'. Fail-safe se il gap non
  e' calcolabile. Check polvere PRIMA di _quantize_step (che clampa al lotto
  minimo: un residuo 1e-17 diventava un ordine nudo da un lotto).
- _real_close: market_amt = filled_amount anche a merged verified=False (i
  contratti chiusi dal reduce-only non si buttano se il leg netting fallisce);
  REAL_CLOSE_PARTIAL non piu' gateato su verified (era soppresso proprio nel
  caso parziale reale).
- pairs: verita' per-FRAZIONE di gamba (gross proporzionale al fillato, orfano
  = solo il residuo — prima falsava reconciler e real_capital della parte gia'
  chiusa); REAL_OPEN_PAIR booka filled_amount; docstring applied corretta.
- open_pair unwind: chiude il FILLATO, non il richiesto (senza il cap silenzioso
  del reduce-only avrebbe mangiato quota altrui).
- place_tp_limit: quantize CONSERVATIVO (sell=floor/buy=ceil) — il rounding al
  tick piu' vicino poteva mettere il resting oltre il TP sim -> tocco genuino
  classificato phantom sistematicamente.

ROBUSTEZZA/OSSERVABILITA':
- runner: WORKER_ERROR_STREAK a 5 e poi ogni 50 poll + recovery RIPRESO +
  flag real_in_position nell'alert (prima: one-shot a n==5, poi silenzio).
- _tp_phantom: TTL 120s sul verdetto (era ~50 HTTP/h per worker a barra
  fantasma); merge notes con entrambi gli order_id (audit-trail).
- reset_flatten: _quantize_step Decimal (round float produceva amount che
  Deribit rifiuta); hourly_report: book XS01 con gambe SHORT visibili (abs).
- validate_xsec_worker: POS/LEV importati (non hardcoded); xs01_tranche:
  regression-lock ESEGUITO vs xsec_sim; reconcile su src/live/books;
  drift_monitor: rolling vettoriale + exit code 1 su warn.

Test: +4 guard/dust, fixture filled_amount -> 114 passed.
Deferiti (TODO): resting esposti al netting, lifecycle orphan_legs, finestra
trade-history TP_PHANTOM, validazione feed a monte, dedup minori.

"""PairsWorker — paper trading a 2 GAMBE per la famiglia PR01 (spread reversion).
Market-neutral: long asset A / short asset B (o viceversa) sullo z-score del log-ratio.
Distinto dallo StrategyWorker single-leg: gestisce due strumenti, due prezzi di
ingresso, e conta le fee su ENTRAMBE le gambe (2*fee_rt*lev = 0.20% RT/coppia con
fee_rt=0.001). Semantica identica al backtest scripts/analysis/pairs_research.pairs_sim:
r[i] = log(closeA[i]/closeB[i]); z[i] = (r[i]-SMA_n(r)[i]) / STD_n(r)[i] (causale)
ENTRY a close[i]: z<=-z_in -> LONG ratio (long A / short B); z>=+z_in -> SHORT ratio
EXIT: |z| <= z_exit (rientro) oppure time-limit max_bars
filtro candele sporche: salta l'ingresso se |dr[i]| > jump_max
PnL = (retA - retB) * direction * lev - 2*fee_rt*lev (notional uguale per gamba)
Stato persistente (resume al restart) e log come StrategyWorker.
