X_DECLARATION_READER_PIN_STALE
Means
a pin in that ratchet no longer holds
Typical cause
two causes, one code, and the cause says which: the key gained a reader, so the pin would let the next dead key in beside it; or the key was deleted, so the pin outlived its key and records a debt that cannot come due
Fix
edit scripts/declaration-readers.ts — delete the waiver in DECLARATION_READER_PINS for the leaf the finding names
