2026-08-04 audit, Batch D. Verification outcomes (no behavior changes —
comment + tests only):
- CP gate-bypass (quality forced to B after the gate chain, exhaustion/
M5-score gates not re-checked) is VALIDATED behavior, not a bug: the
pinned shipped-config M5 12mo book carries 226/586 XAU_CP trades
(+38.9R), 104 with EXHAUST warnings (+15.3R), 175 below the M5
min-score gate (+28.0R). Removing the "holes" removes validated
profit. New test pins the shipped state (PB off, CP BUY-only on M5,
ema_partial_neutral M5-only) so any flip is a conscious revalidated
decision.
- E18 (xau_strategy vs backtest blocked-hours "drift") REFUTED as a
defect: the divergence is required by pair isolation — the backtest
copy is the generic non-XAU fallback and must not inherit
gold-validated deltas. Documented in the factory + a test asserting
the delta stays XAU-side.
- 6c-upgrade re-arming an exhaustion-D refuted (exhaustion zeroes
confidence below 6c's floor; regimes mutually exclusive). "WEEKEND
FILTER" CP-suppression branch is defense-in-depth for direct
analyze_from_dataframes callers, kept.
Suite: 316 green.

Gate 6h (big-candle entry gate): blocks all XAU entries (core, XAU_PB,
XAU_CP) when the primary TF's last 24h contains a bar with range >= K x
prior-bar ATR. Ships default-OFF: validation rejected every threshold
(K 3-6 on M5/M15 12mo) — removed trades were net-POSITIVE at every cell;
M5 quiet-window trades are the only losing bucket. Config knobs
big_candle_atr_multiple/lookback_hours, --big-candle backtest flag,
Module 17 tests.
M5 relaxation SHIPPED (validated 2026-07-30, Oanda bars, $0.30 spread):
m5_min_abs_score 30->25, m5_min_confirmation_score 10->5, hour-21 UTC
unblocked M5-only. Beats control in ALL 6 calendar years of the 5yr
replay (+230.9R/2319 PF 1.26 DD 21.3 vs +168.0R/2048 PF 1.21 DD 27.0),
12mo +107.4R PF 1.36 vs +84.6R PF 1.33, OOS +26.1R vs +17.2R, $0.70
spread +86.9R vs +66.4R. M15: every relaxation retested negative —
config unchanged. Declined-but-open: M5 hour-22 block, M15 hour-16
unblock (both fail 5yr/OOS). Evidence in the factory docstring.
Tooling: generic --set PATH=JSON research override in gpu_backtest
(typo-proof, logged); diagnose_filters filter_tags refreshed for gates
6d-6i with a staleness-guard test (Module 18); research scripts
hour_analysis/burst_profile/book_diff. Suite: 268 tests.

Same-day sibling of the M15 campaign, opposite finding: on M5 the arm
point barely matters — winners need a looser leash. 5yr grid plateau
arm 0.5-0.7 x dist 0.85-1.0; shipped the OOS-preferred edge 0.60/0.85:
+231.2R PF 1.30 vs +218.0R PF 1.29 baseline, both halves better, DD
flat (19.2 vs 19.1), OOS +14.5R vs +11.1R. dist 1.0 rejected at the
OOS gate despite best in-sample total. XAU_PB pb_trail unaffected.
Factory replay reproduces the grid cell; 201/201 tests.

Parity: replay now applies the live _apply_regime_filter_live method
under the live guard (function-identity, default-off); unregistered-pair
fallback applies the config.json overlay; parity sweep gains direct
ATR/vol-regime assertions; regime-filter semantics test added.
Trail campaign: --trail-arm/--trail-dist research flags; 30-cell grid on
5yr M15 refuted the earlier-arm hypothesis and found the 0.70-0.80 arm
plateau. Shipped M15-only trail_arm_r=0.70 (factory override):
+210.7R PF 1.35 WR 57.8% vs +175.7R PF 1.30 WR 53.9% baseline; both
halves and 2024-06->2025-03 OOS better (+57.4 vs +45.4); 5yr max-DD
clause (33.9R vs 29.1R) explicitly waived by owner. M5 unchanged.
Factory replay reproduces the grid cell trade-for-trade; 201/201 tests.

Implements Task 2: apply_pair_overrides in xauusd.make_config before
the validated per-TF deltas, so e.g. M5 hour-9 appends on top of the
JSON base. Updated Module 9 equivalence test and added three parity pins.

M5 factory: cp_enabled=True, patterns limited to inv_hs, double_bottom,
bull_flag. SELL CP lost -3.21R on OOS; BUY CP: +41.8R PF 1.60 on 12mo,
+65.2R PF 1.48 on 5yr. Adds +22R to the M5 book (708 vs 513 trades).
M15/H1 remain disabled — all failed OOS validation.

M15 mixed-"trending" regime block (ADX strong, EMAs unaligned =
momentum without direction): -6.8R/24 trades on 12mo, negative both
halves; blocking scores +65.7R/499 PF 1.38 DD 10.4R vs +59.0R/521
PF 1.32 DD 12.6R, better both halves, OOS 2024-06->2025-03 neutral
(-1.4R = the 4 such trades there). M5 never trades this regime.
New XauStrategyConfig.blocked_regimes / sell_blocked_regimes knobs
(default empty) + aggregator gate 6g2; M15 factory opts in.
M5 hour-9 UTC block (post-London-open whipsaw): -28.9R/143 over the
6-year book, negative 5/7 calendar years. Full-history replay with
block: +207.1R vs +178.3R, max DD 28.7R vs 35.5R, 2023 -13.0R ->
breakeven; tuned 12mo book unchanged (139.0 vs 139.3). Hour 9 is
positive on M15 (+1.7R 6yr, +8.6R OOS) so the block is factory
M5-only.
Rejected after validation (documented in xauusd.py + session memory):
transitioning-SELL block (bull-market artifact, +5.7R in 2024 OOS),
M15 trending_down block (M5 cross-TF contradiction), losing-streak
circuit breakers, 30d efficiency-ratio trend gate, and all entry-level
indicator filters (winners == losers at entry on every feature).
Full-history context (Twelve Data 5min starts 2020-03-16): M5 6.3yr
+207R PF ~1.3 post-fix with losing year 2021; M15 +152.6R PF 1.19
DD 49.7R — edge is regime-dependent, chop years are structural.
Tests: 178 passed (new gate test + factory-equivalence updates).

Finishes PENDING_STEPS Step 1 under the current trailing-exit model.
M15 window 2025-03-30->2026-05-31 ($0.30 spread): +116.6R/460 PF 1.83
vs +105.4R/424 PF 1.82 baseline, better in both halves; 2024-06->
2025-03 OOS +30.3R vs +10.6R control. Same knob on the pinned M5 book
is WORSE (+131.3R/699 vs +139.9R/547) so the override is M15-only in
the xauusd factory, per the pre-registered decision rule. M5 path
unchanged (factory override gated on primary_tf == M15).

Ported from feature/eurusd-support: PAIR_PRODUCERS registry with
make_config() factories per pair. xauusd.make_config is a pure
PlatformConfig-defaults wrapper (equality with the inline construction
is enforced by test); eurusd.make_config carries the donor branch's
regime weights and gates as a pre-realism baseline.
Adds 4 registry tests. 154/154 pass.
