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).
  1. 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.
  1. 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).
  1. 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.
