Current head 1a9b6bbc3e8f now has a fresh 5/5 subscription-backed review with zero findings, both prior threads are resolved, CI passes, and the PR is mergeable/clean. I did not merge: the required multi-pass review and independent consensus gate both fail closed because the scoped OpenRouter review key is credit-capped (HTTP 402). Waiting for review-budget recovery or human merge; no quality-gate bypass used.

Current head 9aa883416ce8 now has a fresh 5/5 subscription-backed agent review with zero findings (P2 50fb65cf9508 suppressed as resolved). CI is green and the PR is MERGEABLE/CLEAN. I did not merge: self-merge-check.py refuses an agent review with no 2-of-3 consensus record. LLM consensus is still blocked on OpenRouter prepaid credits (HTTP 402), not a daily-key reset. Greptile was already requested on this head and is still awaiting. Waiting for credit recovery, a Greptile current-head review, or human merge. No quality-gate bypass used.
