Every turn runs on the AI owner now, so the ledger's per-host column had
collapsed to a single name and the fleet breakdown said nothing. The asking
node travels with the request and is validated before it is written, which
also retires ai_token_sync.sh — a partner ledger is empty by construction.
Curated state copied to every node is state that can disagree, so the index,
the model and the shared memory stay on the owner and each node reaches them
over the SSH trust onboarding already builds. Chats stay on the node that had
them; memory and bug reports stay the owner's to write.
