Setup's marker detection reports a conventions file it can never write as a resolvable marker.missing gap: classifyMarker (internal/core/ahoy/marker.go) folds every read error into markerMissing, so an AGENTS.md (or the chosen target file) that is a directory, a FIFO or unreadable raises a required, resolvable gap, install's write then refuses it ('it could not be read'), and the repository stays partial on every run with a gap install promises to close and never can.

Grounds

• pursued: install over each unreadable AGENTS.md leaves no marker.* id in Remaining and detection raises only non-resolvable marker gaps; a marker.missing or a resolvable marker gap for any of the three would show it wrong
