Progress Log - 2026-02-26

Scope Covered Today

• Sprint tranche execution and validation from 206 through 227.
• Hard benchmark reruns on:
  • challenging_subset_prod_2026-02-26.jsonl
  • challenging_fullstack_multifile_2026-02-26.jsonl
• Production-loop anti-false-green hardening, projection/fullstack contract enforcement, parity gating, and parity remediation.

Key Outcomes

1. Sprints 206-211:

• Added anti-false-green production evidence gating.
• Added projection-contract validation and parity/efficiency/intent consistency analyzers.
• Status: PARTIAL (diagnostics/enforcement improved, parity and readiness still weak at that stage).

2. Sprints 217-221:

• Implemented multi-file/fullstack contract gates (migration/security/SLO/rollout checks).
• Added fullstack closure analyzer and execution tracker.
• Status: IMPLEMENTED, then PARTIAL until parity inconsistency was addressed.

3. Sprints 222-224:

• Added strict AB/production parity hard gate and summary metrics.
• Eliminated unresolved divergence by blocking inconsistent runs.
• Status: DONE (for gating/reporting behavior).

4. Sprints 225-227:

• Added deterministic path-B repair layer:
  • C++ include repair for std::vector.
  • Go/Rust queue transpile skeleton normalization.
• Integrated repair into AB path-B flow.
• Fixed Rust gate harness initialization issue.
• Validation result on latest reruns:
  • challenging_subset_prod_20260226_r7: ab_prod_divergence_count=0, ab_consistency_blocked_count=0
  • challenging_fullstack_multifile_20260226_r7: ab_prod_divergence_count=0, ab_consistency_blocked_count=0
• Status: DONE.

Remaining Risk (Important)

• Current path-B repair closure is pattern-driven around recurring queue-shaped transpile failures.
• Next required tranche: broaden to non-queue semantics and first-class spec-to-execution-ready planning.
