Make fallback coverage something that can actually happen, and say so on the page

Browse Source 
fallback.sh starts covered containers with docker start and never creates them, so a coverage list
the partner has never been sent is a promise nothing can keep — all twelve were missing. Adds the
push and remove paths, a readiness card that checks rather than infers, and the fallback state the
assistant needs to answer for it.

// ── A live daemon that has simply never transitioned ────────────────────────────────

// nothing at all. So a node that has run cleanly since it was built has no file, and

// daemon is dead. Those are opposite conditions and they were rendered identically.

// because there genuinely is no file; 'inferred' says where the verdict came from instead.
