# Sprint 244 Execution Tracker - 2026-02-26

## Scope
- `sprint244_plan.md`

## Implemented

New first-pass autofill tool:
- `tools/mcp/synthesize_native_profile_autofill_tasks.py`
  - Detects active impact profiles from spec.
  - Evaluates missing coverage against current native tasks.
  - Synthesizes profile-specific autofill task bundles.

Pipeline integration in `tools/mcp/run_sprint_taskitem_pipeline.sh`:
- Added controls:
  - `WSTONE_NATIVE_PROFILE_AUTOFILL` (default `0`)
  - `WSTONE_NATIVE_PROFILE_AUTOFILL_MAX_TASKS` (default `12`)
- Autofill runs before native impact coverage gate and can inject tasks directly.
- Autofill task injection is reflected in `extra_tasks` and summary packet:
  - `native_profile_autofill`

## Validation Artifacts

A/B with coverage gate (non-enforced):
- autofill ON:
  - `logs/taskitem_runs/TEST_ONLY_sprint244_autofill_20260226_151651/00_summary.json`
  - coverage: `failing_profile_count=0`
- autofill OFF:
  - `logs/taskitem_runs/TEST_ONLY_sprint244_autofill_20260226_151652/00_summary.json`
  - coverage: `failing_profile_count=7`

Enforced gate behavior:
- pass with autofill ON:
  - `logs/taskitem_runs/TEST_ONLY_sprint244_autofill_enforce_20260226_151709/00_summary.json`
- fail with autofill OFF:
  - `logs/taskitem_runs/TEST_ONLY_sprint244_autofill_enforce_20260226_151710/06_native_impact_coverage.json`

## Explicit Completion Signal

- Sprint 244: `DONE` (implemented + enforced pass/fail behavior verified)
