"""XAU/USD signal producer config.

PlatformConfig defaults ARE the tuned XAU/USD configuration, so this
factory sets the timeframes plus documented per-timeframe overrides.
It must stay equivalent to the inline PlatformConfig(symbol=XAUUSD,
...) construction (plus those overrides) used by the backtester and
Telegram bot (enforced by a test in test_all.py).

M15 override (validated 2026-07-11, window 2025-03-30 -> 2026-05-31,
$0.30 spread, trailing exits): tp_floor_rr 1.0 scores +116.6R/460
trades PF 1.83 vs +105.4R/424 PF 1.82 at the 0.5 default — better in
both train/val halves and on the 2024-06 -> 2025-03 out-of-sample
window (+30.3R vs +10.6R; the 1R floor lifts targets past the min-TP
spread gate, roughly doubling trades there). The same knob HURTS M5
(pinned 12mo book: +131.3R/699 vs +139.9R/547, PF 1.55 vs 1.78), so it
is per-timeframe, exactly as PENDING_STEPS' decision rule anticipated.

M15 override 2 (validated 2026-07-11, 12mo window 2025-07-11 ->
2026-07-11 + OOS 2024-06-01 -> 2025-03-30, $0.30 spread): block the
mixed "trending" regime (ADX strong but EMAs unaligned — momentum
without directional structure). Those trades lost -6.8R/24 on 12mo,
negative in BOTH halves; blocking scores +65.7R/499 PF 1.38 DD 10.4R
vs +59.0R/521 PF 1.32 DD 12.6R baseline, better in both halves. OOS
is neutral (-1.4R = the 4 such trades that existed there; no power to
confirm or refute). M5 never trades this regime (its gates already
exclude it), so the block is M15-only. A second candidate — blocking
transitioning-regime SELLs (-4.0R/47 on 12mo) — was REJECTED: those
sells made +5.7R/32 in the 2024 OOS window (bull-market artifact).

M5 override (validated 2026-07-11, full-history replay 2020-03-17 ->
2026-07-11 + 12mo book, $0.30 spread): block hour 9 UTC (post-London-
open whipsaw). Hour-9 entries lost -28.9R/143 over 6 years, negative
in 5/7 calendar years including winning years (2022 -9.2R). Blocking:
+207.1R vs +178.3R baseline on the 6-year replay, max DD 28.7R vs
35.5R, improves 5/7 years (2023 goes -13.0R -> breakeven); the tuned
12mo book is unchanged (+139.0R vs +139.3R). M15-and-up keep hour 9:
it is POSITIVE there (M15 6yr +1.7R, M15 OOS +8.6R), so the block is
M5-only, same per-timeframe pattern as the M15 overrides.
