Sprint 260 Execution Tracker - 2026-02-26

Scope

• sprint260_plan.md

Implemented

New tool:

• tools/mcp/synthesize_raw_signal_targeted_variants.py
  • Reads prioritized missing signals from raw backlog.
  • Emits focused and bundled normalized-requirement variants keyed to signal class.

Pipeline integration in tools/mcp/run_sprint_taskitem_pipeline.sh:

• Added:
  • WSTONE_NATIVE_RAW_SIGNAL_TARGETED_VARIANTS
  • WSTONE_NATIVE_RAW_SIGNAL_TARGETED_MAX_VARIANTS
• Raw search now optionally merges:
  • profile variants (synthesize_raw_candidate_requirement_variants.py)
  • signal-targeted variants (synthesize_raw_signal_targeted_variants.py)
• Added summary packet:
  • native_raw_signal_targeted_variants

Validation Artifacts

OFF:

• logs/taskitem_runs/01a_fallback_intake_spec_20260226_163629/00_summary.json

ON:

• logs/taskitem_runs/01a_fallback_intake_spec_20260226_163556/00_summary.json
• generated signal variant payload:
  • logs/taskitem_runs/01a_fallback_intake_spec_20260226_163556/02ae_raw_signal_targeted_variants.json

Observed result on hard sample:

• OFF: available_variants=2, attempted_variants=3, selected_variant=0
• ON: available_variants=8, attempted_variants=8, selected_variant=0
• best_top_gap_score remained 0 and failing_profile_count remained 1

Explicit Completion Signal

• Sprint 260: DONE (implemented + validated; intrinsic uplift still pending)
