Restoring a real 13-app repository onto a fresh install: 11 came back working.
matrix failed because its install hook writes homeserver.yaml with the new DB
secret and the restore then lays the old one back over it; stoat failed because
rabbit's mnesia dir restores raw and the broker only honours
RABBITMQ_DEFAULT_PASS on an empty data dir.
Apps with a dump descriptor are unaffected — those clear the data dir so the
engine initialises with the current secret, then replay the dump. That is the
tell for what the general fix has to look like.
Not implemented: applying the restored system config on first run changes what a
restore does with credentials (including the WebUI login), which is a decision,
not a defect. Written up as §3.6 with a recommendation.
