The delimiter detector TestNoPrivateDelimiterCompare fails on the tip that carries the drain's own-rule reader: internal/core/decide/decide.go spells four frontmatter delimiter literals against an allowlist of two, because renderStated (added with decide.CreateStated for the ahoy drain-rule offer) cuts the skeleton it just rendered at its close with a private strings.Index search for the delimiter and writes a second block. The lane gates of that change ran only the touched packages, so go test ./... fails at internal/core/frontmatter.

Grounds

• pursued: the delimiter detector passes on the drain tip with the allowlist unchanged and both renderers write the bytes they wrote before; shown wrong if TestNoPrivateDelimiterCompare fails again or a decide test sees a different record
