What

If the combined projects.json is missing, projects are read from the individual projects/*.json files instead, and the archive summary is rebuilt from users.json plus per-conversation message counts rather than being required in the file.

export zip missing required entry
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
