Sub-project A of the production-readiness roadmap. Single-branch,
phase-gated: measurement substrate → parallel investigation tracks
(magnitude collapse + reward V7 audit) → single convergence commit →
6-fold × 50-epoch L40S validation.
Target criteria at close:
A (action dist): F_Half/F_Full each ≥15% on ≥4/6 folds, WinRate
55-65%, ≥100 trades/val window
B (multi-fold): Best Sharpe > 10 on ≥5/6 folds, WinRate > 55% on
≥5/6 folds
Greenfield checkpoint policy — any action-space or weight-shape change
is allowed. All confirmed bugs fix together in one Phase-2 commit.
V7 discipline gates inclusion (measurement confirms the bug), no
ranking across findings.
Out of scope for this spec: paper trading (sub-project C), canary
deployment (sub-project D), hyperopt re-runs, architectural changes
beyond action space.
Awaiting user review before invoking writing-plans.
