Sprint 263 Execution Tracker - 2026-02-26

Scope

• sprint263_plan.md

Implemented

New tool:

• tools/mcp/project_raw_candidate_structure.py
  • Normalizes raw tasks against top-gap missing-signal classes.
  • Fills missing ops/reasons/execution contract fields.
  • Expands shallow task sets to gap-indicated minimum count.

Pipeline integration in tools/mcp/run_sprint_taskitem_pipeline.sh:

• Added:
  • WSTONE_NATIVE_RAW_STRUCTURAL_PROJECTOR
• Raw candidate search now optionally projects:
  • baseline candidate (02ae_candidate_0_projected_tasks.json)
  • each generated candidate variant (02ae_candidate_<n>_projected_tasks.json)
  • adaptive retry candidate when enabled
• Added summary packet:
  • native_raw_structural_projector

Validation Artifacts

OFF:

• logs/taskitem_runs/01a_fallback_intake_spec_20260226_165737/00_summary.json

ON:

• logs/taskitem_runs/01a_fallback_intake_spec_20260226_165746/00_summary.json
• projected artifacts:
  • logs/taskitem_runs/01a_fallback_intake_spec_20260226_165746/02ae_candidate_0_projected_report.json
  • logs/taskitem_runs/01a_fallback_intake_spec_20260226_165746/02ae_candidate_0_projected_tasks.json

Observed result on hard sample:

• Raw search score improved sharply under projector:
  • best_failing_profile_count: 1 -> 0
  • best_top_gap_score: 0 -> 88
  • best_task_count: 2 -> 6
• Residual parity gap:
  • native_impact_coverage.failing_profile_count remained 1
  • indicates score-tool vs coverage-gate semantics are not yet aligned.

Explicit Completion Signal

• Sprint 263: DONE (implemented + validated; uncovered scorer/gate parity gap)
