Cold Validation Architecture goes open source

This is less a code-review bot than a control plane for AI-assisted change management. The smart move is treating review as an independent audit, not a second chat turn on the same model.

• –The reviewer runs cold in an isolated temp directory, so it never inherits the builder's reasoning or sunk cost.
• –Fingerprinted findings plus an append-only adjudication ledger make reruns stable instead of noisy.
• –Max two rounds per phase and controller-side stall detection keep the process finite.
• –Builders can disagree with findings using recorded rationale, which is healthier than forcing blind churn.
• –Bash scripts and JSON schemas keep the system portable, while the retained acceptance report gives security and compliance teams something durable to review.
