What

Rewinding a conversation no longer leaves stale read-file timestamps behind, so re-reading a file after a rewind is not blocked.

Details
  • The sliced-off messages are scanned for read file paths and nested memory paths.
  • Those entries are dropped from the read-file tracking map and from the nested memory record.
Evidence

nestedMemoryPaths

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