# Sprint 236 Execution Tracker - 2026-02-26

## Scope
- `sprint236_plan.md`

## Implemented

- Added semantic fallback audit tool:
  - `tools/mcp/analyze_semantic_fallback_gaps.py`
- Analyzer outputs:
  - `semantic_fallback_records.jsonl`
  - `semantic_fallback_summary.json`
  - `semantic_fallback_tooling_recommendations.json`
- Added deterministic root-cause classes:
  - `native_decomposition_too_shallow`
  - `semantic_rationale_missing`
  - `native_decomposition_and_semantic_signal_deficit`
- Added per-run remediation metadata:
  - `recommended_tools`
  - `recommended_taskitem_constraints`

## Baseline Audit Artifact

- `logs/taskitem_runs/TEST_ONLY_sprint236_semantic_fallback_audit_20260226/semantic_fallback_summary.json`
- `logs/taskitem_runs/TEST_ONLY_sprint236_semantic_fallback_audit_20260226/semantic_fallback_tooling_recommendations.json`

Observed in this slice:
- `record_count=5`
- `fallback_rate=1.0`
- dominant root cause: `native_decomposition_and_semantic_signal_deficit`

## Explicit Completion Signal

- Sprint 236: `DONE` (implemented + audit generated + dated metadata captured)
