Same 8-run matrix, window and pinned input parquets as baseline/da61cff;
every output hash is byte-identical to the old baseline (walk-forward
mode + data-safety guards are behavior-neutral on default runs).
Verified: scripts/compare_baseline.py 32/32 PASS at this commit. Future
compares now reference the extended-window code. da61cff kept for
history; its pins remain protected (guard unions all manifests).
