• fix(settings): unify write and source_edit validation gates #467 (write/source_edit validation gates, merged 2026-10-15) is a ninth instance of the sibling-paths class tracked in Recurring defect class: sibling paths enforce weaker subsets of the same contract #451; noted there as a comment rather than a new entry since the class is already escalated and has a principle (docs/principles/sibling-paths-share-the-contract.md, docs: promote the sibling-path lesson to a repository principle #472).
