@@ -51,7 +51,9 @@ A new module `src/fxhnt/application/gate_policy.py`:
- reconciliation: `min_forward_days: int`, `recon_tolerance_frac: float`, `recon_min_band: float`,
`recon_min_corr: float`, `max_gap_days: int`
- absolute: `min_days: int`, `min_total_return: float`, `min_sharpe: float`
- promotion: `promotion_max_corr: float` (the auto-corr backstop threshold)
- promotion: `promotion_max_corr: float` (the auto-corr backstop threshold) + `promotion_min_overlap_days:
int` (minimum overlapping days for a valid correlation — below this the corr is indeterminate and
promotion is withheld). Both are covered by `policy_hash`.
- `POLICY_VERSION: int` — bumped on ANY change to the policy defaults (auditable; dev-controlled).
- `policy_hash(policy: GatePolicy, version: int) -> str` — sha256 of the canonical policy fields + version
(content-derived; a forgotten version bump still changes the hash → the self-check test fails).
