+# Sprint 255 Plan: Raw Top-Gap Hardening Pass
+
+## Goal
+Close the highest-frequency raw-only gap classes inside the first-pass native task set by hardening prerequisite ops, deterministic execution contract fields, and reason keyword density.
+
+## Steps
+- Step 2320: Add a raw hardening tool that activates impact profiles from spec keywords.
+- Step 2321: Inject required prereq ops/reason keywords/execution contract fields into native tasks.
+- Step 2322: Enforce profile-derived minimum native task count by deterministic cloning.
+- Step 2323: Integrate hardening stage into pipeline before shape/multishot/autofill overlays.
+- Step 2324: Emit hardening telemetry and run A/B validation artifacts.
+- Step 2325: Add `Sprint255IntegrationSummary.h` and execution tracker.
