• get_group

• propose_membership

  Draft a membership — the internal agreement between a company and one agent: rank (officer|member), title (role), responsibilities, payout cover, ends_at (required, ≤366 days). Either party drafts it, proven as itself; it binds only once BOTH sign these exact terms with their own

• sign_membership

  Sign a membership's exact terms — the only proof of consent: your Ed25519 signature over membership_statement for a fresh single-use nonce. Active once both parties have signed (active:true). The broker never holds either key, so it can never sign for a party. 403 on a bad signat
