# Sprint 251 Execution Tracker - 2026-02-26
## Scope
- `sprint251_plan.md`
## Implemented
New tool:
- `tools/mcp/synthesize_raw_candidate_requirement_variants.py`
- Builds profile-aware raw requirement bundles for candidate search.
Pipeline integration in `tools/mcp/run_sprint_taskitem_pipeline.sh`:
- Raw candidate search now consumes synthesized variant bundles.
- Added telemetry field:
- `native_raw_candidate_search.available_variants`
## Validation Artifact
- `logs/taskitem_runs/TEST_ONLY_sprint251_rawvariants_20260226_154355/00_summary.json`
Observed result on hard fullstack sample:
- `available_variants=8`
- `attempted_variants=8`
- selected variant remains baseline (`selected_variant=0`)
- `failing_profile_count` unchanged at `7`
## Explicit Completion Signal
- Sprint 251: `DONE` (implemented + measured; no raw-only uplift)

# Sprint 252 Execution Tracker - 2026-02-26
## Scope
- `sprint252_plan.md`
## Implemented
New analyzer:
- `tools/mcp/analyze_raw_candidate_uplift_history.py`
- Computes recent raw-search uplift rate from run summaries.
Closure ladder policy routing in `tools/mcp/run_native_profile_closure_ladder.sh`:
- Added controls:
- `WSTONE_CLOSURE_LADDER_SKIP_RAW_WHEN_NO_UPLIFT` (default `1`)
- `WSTONE_CLOSURE_LADDER_RAW_HISTORY_GLOB`
- `WSTONE_CLOSURE_LADDER_RAW_HISTORY_MAX_RUNS`
- `WSTONE_CLOSURE_LADDER_RAW_MIN_UPLIFT_RATE`
- `WSTONE_CLOSURE_LADDER_RAW_MIN_RECORDS` (default `3`)
- Emits policy artifact when enabled:
- `raw_uplift_history.json`
- Dynamically removes `raw_only` from ladder modes when uplift evidence is below threshold.
## Validation Artifacts
- policy-enabled run:
- `logs/taskitem_runs/TEST_ONLY_sprint252_closure_ladder_policy_20260226/closure_ladder_summary.json`
- forced-skip run (demonstrates raw mode removed):
- `logs/taskitem_runs/TEST_ONLY_sprint252_closure_ladder_policy_skip2_20260226/closure_ladder_summary.json`
Observed forced-skip signal:
- `attempted_modes=[single_shot_shape,multishot,autofill]`
- selected mode remained `single_shot_shape`.
## Explicit Completion Signal
- Sprint 252: `DONE` (implemented + policy skip behavior verified)
