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.
