2026-08-04 Fable 5 QA audit, Batch A. All fixes are execution-robustness only — no signal code touched (git diff scope: daemon/executor/tests). Findings verified by runnable repros before fixing (h3 harness): - close_trade: a 200 whose close order was created but NOT filled (e.g. MARKET_HALTED during the settlement pause) now raises instead of returning; the daemon's timeout path keeps tracking and retries. The old path popped state and orphaned a live position forever (reconciliation was boot-only). - place_market_order: positionFill=OPEN_ONLY — on a netting account an opposite-side order can no longer silently close an untracked position; the divergence surfaces as an order cancel. - _execute_trade: a fill without tradeOpened (netting close/reduce) and any placement OandaAPIError (server may have filled before a network timeout) now trigger _reconcile_positions instead of silent return. - _discover_existing_positions → lock-guarded _reconcile_positions, callable mid-run; adoption of a position with NO broker stop now screams (CRITICAL + per-bar warning) instead of computing sl=entry, risk=0 and silently never trailing. - _manage_trailing: snapshot deep-copies per-trade dicts (no mutation of live state outside the lock); write-back skips trades popped by _check_closed_trades mid-iteration (no ghost resurrection). - Fail-closed config: unknown OANDA_QUALITY_GATE refuses to start (previously a typo silently became the most permissive gate "C"); non-integer OANDA_LOT_SIZE/MAX_HOLD_BARS exit with a clear message. Suite: 302 → 312 tests (Module 21), all green. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01UnZkzeFcTu9agFg8BDh2tn
