2026-08-04 audit, Batch B. Verified first (h1 harness): the two engines are byte-identical on every reachable input — 370-prefix flat-bar deck, warmup band, 322 real-data M15 positions incl. all 7 zero-range bars, zero diffs. The claimed ADX NaN desync / warmup-guard divergences are unreachable below the shared 30-bar analyze() floor. Changes here are therefore observability + hygiene, proven behavior-neutral by exact reproduction of the pinned M15 12mo book (397 trades, +78.7111R, byte-identical trade rows). - _resolve_pos: cache-miss fallback to live-engine recompute now warns on first miss and counts every miss (was fully silent — a run could switch math with no trace). - ROC/Keltner warmup guards textually aligned with the live engine so a future period/floor change can't open a silent divergence window. - New regression: full-sweep parity test comparing ALL indicator signals/confidences, composite, and regimes on every prefix incl. a flat zero-DM/zero-TR run (the old parity test skipped ADX/MACD/ROC/Keltner/RSI entirely); plus a loud-fallback test. Suite: 314 green. Book gate: oanda_m15_12mo_030 reproduced identically. Claude-Session: https://claude.ai/code/session_01UnZkzeFcTu9agFg8BDh2tn
