# Sprint 243 Execution Tracker - 2026-02-26

## Scope
- `sprint243_plan.md`

## Implemented

Pipeline update in `tools/mcp/run_sprint_taskitem_pipeline.sh`:
- 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`.

New remediation task synthesizer:
- `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`

Coverage checker update:
- `tools/mcp/check_native_decomposition_impact_coverage.py`
  - evaluates effective tasks as `native_generated_tasks + extra_tasks`.

## Baseline Validation Artifact

- `logs/taskitem_runs/TEST_ONLY_sprint243_impact_remediation_tasks_loop_20260226_r2/remediation_loop_summary.json`

Observed result on hard fullstack sample:
- before: `failing_profile_count=7`
- after: `failing_profile_count=0`
- delta: `-7`

## Explicit Completion Signal

- Sprint 243: `DONE` (implemented + rerun loop verified with profile-failure closure)
