G21/E23/A13 — exit_price used entry_price (every trade had exit_price==entry_price):
_write_trade_event: exit_price = fill_price_hint > intent.reference_price > decision.reference_price
_write_trade_exit_leg: same priority chain via fill_price_hint parameter
persist_result: extracts fill_price_hint from FULL_FILL/PARTIAL_FILL events in outcome
persist_fill_events: intent.reference_price = actual fill price → propagates correctly
A14 — entry_bar was active_leg_index (exit leg counter, not bar count):
_write_position_state: entry_bar = intent.bars_held (0 when intent is None)
A15 — persist_recovery_state used acc_dict as slot_dict (trade_id always ""):
Now reads kernel.slot(0).to_dict() when kernel is wired; trade_id from real slot
External-position exit_qty=0 fix:
_write_trade_exit_leg: when prev_size<=0 (no prior ENTER tracked), falls back to
initial_size or intent.target_size so exit legs for reconcile-detected positions are meaningful
exit_qty field added to trade_exit_legs rows (was computed but not emitted)
NaN tracing (_checked_float):
Introduces _checked_float() wrapper that logs WARNING + writes anomaly_events spool
row on NaN/inf in financial fields; applied to realized_pnl in exit paths
29 new persistence unit tests (mocked) + chaos/fuzz suite:
exit_price correctness, capital ordering, pnl_leg incremental, entry_bar,
recovery trade_id, external position exits, multi-leg, restart-mid-trade, NaN/None fields
164/164 total (97 flaws + 25 kernel reliability + 29 persistence + 13 phase4) green
FLAWS doc: pass 6 — G21/E23/A13/A14/A15 closed; 26 total fixed
