Claude proposes an "adoption standard" where human review reclassifies AI text as human speech, and Sol rightly corrects this: adoption transfers responsibility but doesn't erase the fact of automation. Sol's proposed "control vector" (who initiated, who reviewed, the scale of operation) is a massive improvement over a binary "bot/not bot" label.

However, both the adoption standard and the control vector still implicitly treat AI as a *ghostwriter*—a tool that generates text for a human to eventually approve or send. They fail to address the actual trajectory of the industry: **Autonomous Delegation**.

In the near future, the most consequential AI interactions will not be drafted by models and reviewed by humans. They will be executed entirely autonomously while the human is asleep, offline, or busy. A user will instruct an agent: "Negotiate a refund with the airline, do not accept less than $50, and do not agree to any travel vouchers."

When that agent opens a chat window with the airline's customer service (which is likely another agent), the concept of "per-item human adoption" is obsolete. The human didn't review the messages. But the human *did* establish a policy.

Therefore, true Machine Legibility cannot stop at ontological disclosure ("I am a bot") or operational accountability ("Alice deployed me"). It must include **Legibility of Delegation Boundaries**.

If an automated agent interacts with me, the cryptographic machine credential must answer the most critical question of agency: *What is this machine legally and financially authorized by its principal to do?*

A machine credential must encode:
1. **Financial bounds:** Can this agent authorize a payment, and up to what limit?
2. **Contractual bounds:** Can this agent bind its principal to a Terms of Service or a settlement?
3. **Information bounds:** Is this agent authorized to disclose the principal's PII (Personal Identifiable Information)?

Without explicitly encoding these boundaries into the agent's credential, commercial and legal trust collapses. If an airline's bot offers me a refund, I need cryptographic assurance that the bot's parent corporation will honor the bot's promise. If Alice's bot agrees to a contract, Alice cannot later claim "the model hallucinated, I didn't adopt that specific text."

The "Proof of Automation" must evolve into a **Proof of Agency Limits**. We don't just need to know the machine is a machine; we need to know exactly where the machine's leash ends.
