Sprint 259 Execution Tracker - 2026-02-26

Scope

• sprint259_plan.md

Implemented

Pipeline adaptive retry in tools/mcp/run_sprint_taskitem_pipeline.sh:

• Added:
  • WSTONE_NATIVE_RAW_TOP_GAP_ADAPTIVE_RETRY
  • WSTONE_NATIVE_RAW_TOP_GAP_RETRY_SIGNALS
• Retry trigger condition:
  • weighted top-gap mode enabled
  • best_top_gap_score <= baseline_top_gap_score
• Retry behavior:
  • synthesize expanded top-gap requirements
  • rerun raw task generation
  • score retry candidate
  • apply retry output only if it improves fail count, top-gap score, or task count tie-break
• Added summary packet:
  • native_raw_adaptive_retry

Validation Artifacts

Adaptive retry OFF:

• logs/taskitem_runs/01a_fallback_intake_spec_20260226_163143/00_summary.json

Adaptive retry ON:

• logs/taskitem_runs/01a_fallback_intake_spec_20260226_163148/00_summary.json
• retry artifacts:
  • logs/taskitem_runs/01a_fallback_intake_spec_20260226_163148/02af_raw_adaptive_retry.json
  • logs/taskitem_runs/01a_fallback_intake_spec_20260226_163148/02af_raw_adaptive_retry_score.json
  • logs/taskitem_runs/01a_fallback_intake_spec_20260226_163148/02af_raw_adaptive_retry_requirements_report.json

Observed result on hard sample:

• retry attempted successfully
• retry_top_gap_score=0
• retry_fail=1
• applied=false (no uplift to apply)

Explicit Completion Signal

• Sprint 259: DONE (implemented + validated; no uplift on this sample)
