X_VERSION_STAMP_PIN_STALE
Means
a page is pinned as naming a version for a reason that is not a stamp, and the page no longer says it
Typical cause
the pin outlived its sentence, so it now excuses whatever lands there next — PUBLISHING.md's git tag v1.1.0 shell line is the shape the pin exists for
Fix
bun run scripts/version-stamps.ts --unpin <path>
