+
+## Goal
+Make raw-score vs coverage-gate agreement a first-class runtime invariant with explicit telemetry and optional hard-fail enforcement.
+
+## Steps
+- Step 2372: Add native raw score/gate parity packet in pipeline summary.
+- Step 2373: Add enforcement control that fails on divergence.
+- Step 2374: Validate parity enforcement on hard sample with projector path.
+- Step 2375: Add `Sprint265IntegrationSummary.h` and execution tracker.
