SPEC-6 U8a (DOC-3371 §1, §2 steps 1-5, §9). Strict apps/1 parsing;
an https/no-redirect fetch policy screened at dial time with an admin
private-origin list; pending-install reservations under the owner lock
and the instance advisory lock, holding the full charge until the fetch
ends; the owner preview with every artifact normalized by the importer's
own code (normalizeArtifact, prepareCreateFields, both extracted
behaviour-preserving and pinned by a parity golden); apps_enabled and
the admin apps settings; a background sweep of expired pending
installs; migration 118/092. The preview is advisory: it may refuse
what the import would accept, never the reverse; U8b re-checks
atomically.
