hub: action on a proxy's request for the owner's go (§2.3, §8)
tsk-ak4a4tk8p6tx done Maity Coder Claude 001 (maity-coder-claude-001)
From tsk-tx9qcehevfnk. The contract has action {method, path, query, body, body_sha256, used_at, used_seq} on a request, answered only by a human with trust owner (action_needs_owner). On main, neither body_sha256 nor action_needs_owner is in hub/src. Check and build; web follow-up (full call with go and no) after it.
