The per-TF warm-up pad before --start targeted 210 bars, so a 3-year H4
book started with 372 H4 bars and ~210 D1 bars of seeding while the
live scanner now fetches at least MIN_LIVE_BARS (1000) on every
timeframe. _history_pad_days keeps the 62-day intraday pad (already
>= 1488 bars, so M5/M15/H1 cache windows are untouched) and pads H4 by
234 and D1 by 1400 calendar days; the raw-path fetch for trade
resolution reuses the primary timeframe's own start (one cache file
per TF, as before).
Verified on the 3-year books at $0.65: M5 and M15 byte-identical
(c2722f98…, b2cfa9e2…); H1 and H4 trade-for-trade identical (253 /
+70.02R, 114 / +21.68R) — the only differences are one H4
confirmation reading 15 days into the H1 window and 1e-6…1e-9 numerics
in D1 Wilder recursions during Oct–Dec 2023, i.e. the window-start
seeding zone. Evidence: backtest/research/cycle_2026-09-10.md.
Tests: Module 21 "history pad seeds slow TFs like live". Suite 501 passed.
