Sprint 261 Execution Tracker - 2026-02-26

Scope

• sprint261_plan.md

Implemented

New tool:

• tools/mcp/synthesize_raw_intrinsic_prompt_pack.py
  • Builds a compact intrinsic prompt pack from top-gap signals.
  • Encodes required ops, executionContract fields, reason keywords, and anti-generic-task constraints.

Pipeline integration in tools/mcp/run_sprint_taskitem_pipeline.sh:

• Added:
  • WSTONE_NATIVE_RAW_INTRINSIC_PROMPT_PACK
  • WSTONE_NATIVE_RAW_INTRINSIC_PROMPT_MAX_SIGNALS
• Added artifacts:
  • 01f_raw_intrinsic_prompt_pack_requirements.json
  • 01f_raw_intrinsic_prompt_pack_report.json
• Added summary packet:
  • native_raw_intrinsic_prompt_pack

Validation Artifacts

OFF:

• logs/taskitem_runs/01a_fallback_intake_spec_20260226_163844/00_summary.json

ON:

• logs/taskitem_runs/01a_fallback_intake_spec_20260226_163855/00_summary.json
• prompt-pack artifacts:
  • logs/taskitem_runs/01a_fallback_intake_spec_20260226_163855/01f_raw_intrinsic_prompt_pack_report.json

Observed result on hard sample:

• prompt pack injected with selected signals (selected_signal_count=8)
• selected_variant remained 0
• best_top_gap_score remained 0
• failing_profile_count remained 1

Explicit Completion Signal

• Sprint 261: DONE (implemented + validated; intrinsic uplift still pending)
