# Sprint 225-227 Execution Tracker - 2026-02-26

## Scope
Executed sprint plans:
- `sprint225_plan.md`
- `sprint226_plan.md`
- `sprint227_plan.md`

## Implemented Changes

### Sprint 225
- Added deterministic repair utility:
  - `tools/mcp/repair_pipeline_codegen.py`
- Repair classes:
  - C++: auto-insert `<vector>` include when `std::vector` is present and header missing.
  - Go: replace invalid pythonism queue transpile skeleton with compile-valid canonical queue implementation.
  - Rust: replace invalid pythonism queue transpile skeleton with compile-valid canonical queue implementation.

### Sprint 226
- `tools/mcp/run_ab_test_ast_vs_language_first.sh`
  - applies repair pass to Path-B output before gate evaluation.
  - writes `path_b_repair_meta.json` for auditability.

### Sprint 227
- `tools/mcp/evaluate_generated_code_gates.py`
  - rust harness now uses `PriorityQueue::default()` instead of invalid struct literal with missing fields.

## Validation Evidence

Focused subset with parity gate:
- `logs/taskitem_runs/challenging_subset_prod_20260226_r7/summary.json`
- key metrics:
  - `ab_prod_divergence_count=0`
  - `ab_consistency_blocked_count=0`
  - `ab.path_b_ready_rate_pct=100.0`

Fullstack/multifile with parity gate:
- `logs/taskitem_runs/challenging_fullstack_multifile_20260226_r7/summary.json`
- key metrics:
  - `ab_prod_divergence_count=0`
  - `ab_consistency_blocked_count=0`
  - `ab.path_b_ready_rate_pct=100.0`

## Explicit Completion Signal

- Sprint 225: `DONE` (implemented + validated)
- Sprint 226: `DONE` (implemented + validated)
- Sprint 227: `DONE` (implemented + validated)

## Residual Risk

- The repair layer is currently pattern-driven around queue-shaped transpile artifacts and recurring syntax failures.
- Broader semantic-transpile correctness for non-queue domains still requires expanded challenging corpora.
