X_CORPUS_UNSCANNED
Means
a whole-tree guard read fewer files than its scope's floor, or could not read part of it, or scripts/lib/workspaces.ts enumerated no publishable workspace (registry-audit, release, list-workspaces)
Typical cause
scripts/lib/corpus.ts reads each scope (source, packages, shipped, tests) once per process; this repository's floor is 1,000 files (500 for tests) and any other root must read at least one. An unreadable directory (EACCES) is refused whatever else was found — a guard over it would report a clean tree it never read
Fix
bun install && bun run verify --only unit — the usual cause is an unreadable or half-checked-out tree
