Sprint 251 Execution Tracker - 2026-02-26

Scope

• sprint251_plan.md

Implemented

New tool:

• tools/mcp/synthesize_raw_candidate_requirement_variants.py
  • Builds profile-aware raw requirement bundles for candidate search.

Pipeline integration in tools/mcp/run_sprint_taskitem_pipeline.sh:

• Raw candidate search now consumes synthesized variant bundles.
• Added telemetry field:
  • native_raw_candidate_search.available_variants

Validation Artifact

• logs/taskitem_runs/TEST_ONLY_sprint251_rawvariants_20260226_154355/00_summary.json

Observed result on hard fullstack sample:

• available_variants=8
• attempted_variants=8
• selected variant remains baseline (selected_variant=0)
• failing_profile_count unchanged at 7

Explicit Completion Signal

• Sprint 251: DONE (implemented + measured; no raw-only uplift)
