X_FIX_SHELL_ARG_PIN_UNEXPLAINED
Means
a package is pinned with a blank reason
Typical cause
a count with no sentence is the waiver axiom 3 refuses: every row is a claim that the value cannot carry shell syntax, and only a human can say which. The count is not honoured either, so the sites are reported behind it
Fix
write where each remaining value comes from in scripts/lib/fix-shell-arg-pins.ts, or wrap them and run bun run scripts/fix-shell-arg.ts --unpin <package>
