# Sprint 241 Execution Tracker - 2026-02-26

## Scope
- `sprint241_plan.md`

## Implemented

Impact list (dated):
- `docs/native_decomposition_impact_list_2026-02-26.md`

Profile set (one-by-one):
- `tools/mcp/profiles/native_decomposition_impact_profiles.json`
- profiles cover 12 impact surfaces:
  - API contract evolution
  - state migration/rollback
  - security propagation
  - SLO/latency budget
  - rollout choreography
  - multi-file transactional edit
  - concurrency/locking
  - projection/environment constraints
  - polyglot boundary changes
  - observability/telemetry integrity
  - data integrity/precision
  - recovery/replay critical flows

Checker + wrappers:
- `tools/mcp/check_native_decomposition_impact_coverage.py`
- `tools/mcp/run_native_impact_coverage_gate.sh`
- `tools/mcp/analyze_native_impact_coverage.py`

Pipeline integration in `tools/mcp/run_sprint_taskitem_pipeline.sh`:
- `WSTONE_NATIVE_IMPACT_COVERAGE_GATE` (default `0`)
- `WSTONE_NATIVE_IMPACT_COVERAGE_ENFORCE` (default `0`)
- `WSTONE_NATIVE_IMPACT_COVERAGE_PROFILES` (profile path)
- emits `06_native_impact_coverage.json`
- summary includes `native_impact_coverage`

## Baseline Validation Artifacts

- soft-gate run:
  - `logs/taskitem_runs/TEST_ONLY_sprint241_impact_gate_20260226_150403/00_summary.json`
- hard-gate run (expected block):
  - `logs/taskitem_runs/TEST_ONLY_sprint241_impact_gate_20260226_150404/06_native_impact_coverage.json`
- multi-profile fullstack sample:
  - `logs/taskitem_runs/TEST_ONLY_sprint241_fullstack_impact_20260226_150416/00_summary.json`
- aggregate report:
  - `logs/taskitem_runs/TEST_ONLY_sprint241_native_impact_aggregate_20260226/native_impact_coverage_aggregate.json`

Observed signal:
- Fullstack sample activated `7` profiles, all failing under current shallow native decomposition.

## Explicit Completion Signal

- Sprint 241: `DONE` (implemented + pipeline-integrated + enforced smoke verified)
