What

Plan and workshop file lookups no longer just check whether a key is present; they tell a cached "this file does not exist" apart from never having looked, wait for a settle step before reading, and recovery after resume or fork stores what it recovered instead of always throwing the entry away.

Evidence

Workshop doc recovered from file snapshot,

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
