code-comments

When a code comment may exist and the human-approval gate that must be cleared before one is written. Use when adding, editing, retaining, or removing any code comment (//, /* */, / */, <!- — -->, {{!- — --}}, #), when reviewing a diff that touches comments, or when asked to clean up / trim / de-stale / de-time-bind comments. This is the single source of truth for comment policy across the repo.
