This unlocked, unprivileged simulation is advisory, not installation authority. Unreadable configuration or changing evidence can make a plan unavailable. File timestamps do not prove repository freshness.

Policy candidates differ from resolved upgrades. Explicit holds are preserved; phased updates are conservatively excluded. Holds, phasing and dependencies can keep packages back. In-memory markings are not installed changes. A later installation could run maintainer scripts, restart services or require a reboot. No automatic rollback is guaranteed. This preview makes no latest-version or zero-vulnerability claim.
