Sprint 246 Execution Tracker - 2026-02-26

Scope

• sprint246_plan.md

Implemented

Pipeline updates in tools/mcp/run_sprint_taskitem_pipeline.sh:

• Added multishot controls:
  • WSTONE_NATIVE_MULTISHOT_DECOMP (default 0)
  • WSTONE_NATIVE_MULTISHOT_MAX_PROFILES (default 12)
  • WSTONE_NATIVE_MULTISHOT_APPLY_MODE (default if_improves)
• Added multishot generator pass behavior:
  • runs additional whetstone_generate_taskitems calls per active profile requirement
  • emits per-shot artifacts:
    • 02ac_generate_taskitems_multishot_<i>_raw.ndjson.json
    • 02ac_generate_taskitems_multishot_<i>.json
  • merges multishot task outputs into effective task set when improved
• Added summary telemetry:
  • native_multishot
  • taskitems.effective_task_count

Validation Artifacts

A/B (autofill disabled, intrinsic boost enabled):

• multishot OFF:
  • logs/taskitem_runs/TEST_ONLY_sprint246_multishot_20260226_152956/00_summary.json
• multishot ON:
  • logs/taskitem_runs/TEST_ONLY_sprint246_multishot_20260226_153033/00_summary.json

Observed delta:

• native_impact_coverage.failing_profile_count: 7 -> 0
• taskitems.effective_task_count: 2 -> 16

Enforced gate behavior:

• pass with multishot ON:
  • logs/taskitem_runs/TEST_ONLY_sprint246_multishot_enforce_20260226_153045/00_summary.json
• fail with multishot OFF:
  • logs/taskitem_runs/TEST_ONLY_sprint246_multishot_enforce_20260226_153047/06_native_impact_coverage.json

Explicit Completion Signal

• Sprint 246: DONE (implemented + enforced pass/fail behavior verified)
