Soul finding on #136: merging pushAll left a legacy-key global under two keys, a store that does not reopen. storedSnapshot hands the global out under its stored key until its first write retires it; the readability walk now asserts nothing else is removed.

CultMesh.flush from a node that never pulled (or holds a stale image) wiped the records it never read. pushAll now merges onto the store under the lock, as push does.
