# Sprint 255 Execution Tracker - 2026-02-26
## Scope
- `sprint255_plan.md`
## Implemented
New tool:
- `tools/mcp/harden_native_tasks_top_gaps.py`
- Activates impact profiles from the input spec.
- Injects required prereq ops, reason keywords, and execution contract fields.
- Expands task count to profile minimum depth when native output is shallow.
Pipeline integration in `tools/mcp/run_sprint_taskitem_pipeline.sh`:
- Added `WSTONE_NATIVE_RAW_HARDEN_TOP_GAPS` (default `0`).
- Added hardening artifacts:
- `02af_raw_hardening_input_tasks.json`
- `02af_raw_hardening_output_tasks.json`
- `02af_raw_hardening_report.json`
- Added summary packet:
- `native_raw_hardening`
- Hardening-appended tasks are added to `extra_tasks` effective set for impact coverage evaluation.
## Validation Artifacts
- OFF:
- `logs/taskitem_runs/TEST_ONLY_sprint255_rawharden_20260226_161923/06_native_impact_coverage.json`

- `logs/taskitem_runs/TEST_ONLY_sprint255_rawharden_20260226_161924/00_summary.json`
Observed result on hard fullstack sample:
- `failing_profile_count: 7 -> 0`
- `taskitems.effective_task_count: 2 -> 6`
- `native_raw_hardening.report.required_ops` includes:
- `whetstone_generate_taskitems`
- `whetstone_queue_ready`
- `whetstone_validate_taskitem`
- `native_raw_hardening.report.required_execution_contract_fields` includes:
- `deterministic`
- `rollbackRequired`
- `replayValidationRequired`
## Explicit Completion Signal
- Sprint 255: `DONE` (implemented + measured uplift on hard sample)

// Sprint 255 integration summary:
// - Added raw top-gap hardening pass for native task output.
// - Hardening injects missing prereq ops/reasons/execution contract fields from active impact profiles.
// - Pipeline now emits native_raw_hardening telemetry and can lift weak raw outputs to profile-ready coverage.

# Sprint 255 Plan: Raw Top-Gap Hardening Pass
## Goal
Close the highest-frequency raw-only gap classes inside the first-pass native task set by hardening prerequisite ops, deterministic execution contract fields, and reason keyword density.
## Steps
- Step 2320: Add a raw hardening tool that activates impact profiles from spec keywords.
- Step 2321: Inject required prereq ops/reason keywords/execution contract fields into native tasks.
- Step 2322: Enforce profile-derived minimum native task count by deterministic cloning.
- Step 2323: Integrate hardening stage into pipeline before shape/multishot/autofill overlays.
- Step 2324: Emit hardening telemetry and run A/B validation artifacts.
- Step 2325: Add `Sprint255IntegrationSummary.h` and execution tracker.
