+# Sprint 247 Plan: Single-Shot Profile Shaping Closure Path
+
+## Goal
+Close impact-profile coverage in single-shot mode (no multishot, no autofill) by shaping the first generated task set with profile-required contracts.
+
+## Steps
+- Step 2280: Add single-shot profile shaping tool over base generated tasks.
+- Step 2281: Integrate optional single-shot shaping stage into pipeline.
+- Step 2282: Merge shaped profile tasks into effective task set and telemetry.
+- Step 2283: Validate enforced gate pass/fail with shaping on/off while multishot/autofill are disabled.
+- Step 2284: Add `Sprint247IntegrationSummary.h` and execution tracker.
