"""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.
