Sprint 235 Execution Tracker - 2026-02-26

Scope

• sprint235_plan.md

Implemented

Pipeline updates in tools/mcp/run_sprint_taskitem_pipeline.sh:

• Added WSTONE_SEMANTIC_TASK_EXPANSION_MODE (default fallback_only).
• Added native decomposition telemetry before semantic expansion:
  • native_task_count
  • native_semantic_signal_count
• Added fallback policy:
  • always: always apply semantic expansion.
  • fallback_only: apply only when native decomposition is shallow.
• Added explicit summary semantics for semantic_task_expansion:
  • enabled=true, fallback_applied=true when semantic fallback expands tasks.
  • enabled=true, fallback_applied=false, skipped_reason=... when enabled but skipped.
  • enabled=false, skipped_reason=semantic_expansion_disabled when feature toggled off.
