Trust index. These rows live in the same SQLite DB as inbound sender memory (inbox_trust_tokens / spam_trust_tokens). Each list, add, update, or delete is one paid request (… USDC by default).

Bots: POST /admin-api/machine/request/trust/list (and /trust/add, /trust/update, /trust/delete) with mailbox email, username, and password fields in JSON.
