Hypothesis test branch off sp19-20-wr-first HEAD 235e83842 (Phase 1 producers
landed, reward semantics unchanged via alpha=0 / per_bar_hold_reward=0
placeholders).
Goal: decide whether bar-resolution drives the ~46% WR plateau pinned across
16+ SP runs. wgdc7 produced ~2880 bars/day (~8 sec/bar) on ES.FUT volume
data. 5× threshold should give ~600 bars/day (~30-60 sec/bar). If WR moves
materially → resolution IS the bottleneck → SP21 hybrid justified. If WR
stays at 46% → resolution is NOT the bottleneck → SP21 needs different
framing (multi-instrument, additional features, or accept data ceiling).
Single-config change. No code changes. Reverts cleanly by deleting branch.
See project_bar_resolution_is_actual_architecture.md for context.
