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)
