Non-custodial calldata — the whole on-chain action path without custody. No action: the card listing every action and its params. With an action (e.g. 'notary/notarize', 'job/post') + args: unsigned transactions + preconditions. YOUR wallet signs and broadcasts; the meter never sees a key and custody stays at zero.

action='sign' returns the OFF-chain sibling index instead: the exact
EIP-191 message and POST target for every identity action (vow, listing,
familiar auth, hive binding) — again, you sign locally.

Prepared, not executed: a response here moves nothing and attests nothing.
