+- Added `WSTONE_EXTRA_TASKS_FILE`.
+- Validates file exists and is JSON array.
+- Appends `extra_tasks` into effective task set before queue/validation.
+- Summary now includes `extra_tasks`.
+

+- `tools/mcp/synthesize_native_impact_remediation_tasks.py`
+  - Creates one deterministic remediation task per failing impact profile with required ops/reasons/contracts.
+
+Remediation loop enhancement:
+- `tools/mcp/run_native_impact_remediation_loop.sh`
+  - now injects both:
+    - `extra_normalized_requirements.json`
+    - `extra_tasks.json`
+

+# Sprint 243 Plan: Profile-Specific Remediation Task Synthesis
+
+## Goal
+Close failing impact profiles by synthesizing deterministic remediation task bundles (not only constraints) and injecting them into rerun decomposition.
+
+## Steps
+- Step 2259: Add pipeline support for externally supplied extra tasks.
+- Step 2260: Synthesize profile-specific remediation tasks from failing checks.
+- Step 2261: Wire remediation loop to inject both constraints and tasks.
+- Step 2262: Ensure impact checker evaluates effective task set (native + injected).
+- Step 2263: Add `Sprint243IntegrationSummary.h` and execution tracker.
