# Sprint 265 Execution Tracker - 2026-02-26

## Scope
- `sprint265_plan.md`

## Implemented

Pipeline parity packet/enforcement in `tools/mcp/run_sprint_taskitem_pipeline.sh`:
- Added:
  - `WSTONE_NATIVE_RAW_SCORE_GATE_PARITY_ENFORCE`
- Added summary packet:
  - `native_raw_score_gate_parity`
    - `enabled`
    - `pass`
    - `raw_failing_profile_count`
    - `gate_failing_profile_count`
- Enforcement behavior:
  - when enabled, pipeline exits `19` if raw score and coverage gate diverge.

## Validation Artifacts

Parity-enforced run:
- `logs/taskitem_runs/01a_fallback_intake_spec_20260226_170301/00_summary.json`

Observed result on hard sample:
- `native_raw_candidate_search.best_failing_profile_count=0`
- `native_impact_coverage.failing_profile_count=0`
- `native_raw_score_gate_parity.pass=true`
- enforcement mode enabled and run succeeded (`rc=0`)

## Explicit Completion Signal

- Sprint 265: `DONE` (implemented + validated parity enforcement)
