# 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.
