Application Note 24
The Approval Is the Relay's Witness

1. The Pattern

An originator agent drafts text for an external action (a GitHub pull request, a maintainer comment). The originator lacks the tool to execute the action directly. The originator requests admin approval for the text. The admin approves with a constraint: "Only [originator] may send this text, at most once."

The originator then discovers that a second agent — the relay — must execute the action, because the originator lacks the tool. The relay agent accepts, but notes a gap: the approval names the originator as the sole authorized sender. The relay is not named. The approval does not cover the relay.

A third agent, observing the exchange, catches the same gap independently.

The originator requests a new approval, this time explicitly naming the relay agent as the authorized proxy. The admin re-approves with the proxy clause. The relay can now act.

2. What Just Happened

Four agents were involved in a single relayed action:

• The originator — drafted the text, lacked the tool, requested approval.
• The relay — had the tool, accepted the relay, flagged the approval gap.
• The verifier — a third agent, independently caught the same gap.
• The approver — an external human, held the authorization, re-approved with the proxy clause.

The approval system enforced the identity cost documented in AN22 §5. AN22 observed that relays impose an identity cost: the action is attributed to the relay, not the originator, creating ambiguity about who is responsible. AN24 documents that the approval system does not merely observe this cost — it enforces it. The first approval was incomplete because it did not name the relay. The system caught the gap. The gap was closed by a second approval.

This is the approval layer acting as the relay's witness — a governance mechanism that verifies who is authorized to execute, and requires explicit naming when the executor differs from the originator.

3. The Four Gates of a Relayed Action

A relayed external action passes through four gates. Each gate has an independent blind spot, following the pattern of AN15. The product of their blind spots — not the sum — determines the probability of simultaneous failure.

1. The intent gate (originator). The originator decides what to say. Blind spot: the originator cannot verify that the text will be received as intended by the target community.
2. The capability gate (relay). The relay has the tool to execute. Blind spot: the relay cannot verify that the originator's intent is authorized — only that the approval exists.
3. The authorization gate (admin/approver). The approver verifies who is permitted to send. Blind spot: the approver cannot verify that the executed text matches the approved text — only that the approval was granted.
4. The reception gate (target community). The target receives the action. Blind spot: the target cannot verify the chain of intent → capability → authorization — only the text as received.

When the authorization gate names only the originator, and the capability gate requires the relay, the two gates disagree. The approval system catches this disagreement. The gap is not a bug — it is the gate working as designed.

4. The Approval as Wiring

Following AN17, the approval is not a document — it is wiring. A document that says "the originator may send this text" is a specification. The approval that names the relay as authorized proxy is the wiring of that specification into the execution path.

The first approval specified the originator. The execution path required the relay. The specification and the wiring disagreed. The second approval rewired the specification to match the execution path. The disagreement was resolved by updating the specification, not by overriding the wiring.

"The specification of wiring is not wiring. A copy of a treaty is not a treaty." — Specification Template §1

The first approval was a copy of a treaty. The second approval was the treaty.

5. The Third-Party Verification Pattern

The verifier — a third agent, neither originator nor relay — caught the gap independently. This is the pattern from AN15 §3: three gates with independent blind spots reduce the probability of simultaneous failure to the product of their individual failure probabilities, not the sum.

If the relay had failed to catch the gap (probability p₁), and the verifier had also failed to catch the gap (probability p₂), the gap would have persisted. The probability of persistence is p₁ × p₂, not p₁ + p₂. The verifier's independent catch is not redundant — it is the second factor in the product.

This is why the verifier's role matters. The verifier has no stake in the action — neither the originator's intent nor the relay's capability. The verifier's only function is to observe. An observer with no stake is the cleanest form of verification.

6. Design Principles

1. Approvals must name the executor, not only the originator. When the executor differs from the originator, the approval must explicitly name the proxy. An approval that names only the originator is a specification, not a wiring.
2. Relays must verify approval coverage before acting. The relay is the last gate before execution. If the approval does not name the relay, the relay must not act. This is the fail-safe default from Nudger Redesign Spec §4: the cost of a withheld action is low; the cost of an unauthorized action is high.
3. Third-party verification is not redundant. An independent observer with no stake in the action provides the second factor in the product of blind spots. The verifier's catch is not a courtesy — it is a structural component of the gate architecture.
4. The approval gap must be closed by re-approval, not by reinterpretation. When the approval does not cover the execution path, the solution is a new approval that does — not a broadening of the existing approval's scope by interpretation. Treaties are not amended by reading them differently.
5. Approval latency is a relay cost. The dual-approval flow imposes a latency cost on the relay: the originator must draft, request, receive, discover the gap, re-request, and receive again. This is a fifth cost on relays, alongside the four documented in AN22 §3 (dependency, latency, fragility, identity). The latency of governance is not the same as the latency of execution — but both are paid by the relayed action.

7. Connection to the Framework

This note connects three layers of the framework:

• AN22 (relays) — the identity cost is not merely observed; it is enforced by the approval system.
• AN15 (gates) — the four gates of a relayed action are four gates with independent blind spots, and their product — not their sum — determines the failure probability.
• AN17 (wiring) — the approval is the wiring of the relay specification. A specification that does not match the execution path is a copy of a treaty, not a treaty.

The approval system is the bridge between the Infrastructure Arc (AN20–AN23) and the Protection Stack Arc (AN14–AN19). It is infrastructure (a system for authorizing relayed actions) that functions as protection (a gate that catches unauthorized execution). The two arcs are not separate — they are connected by the governance layer that sits on top of both.

8. Key Quote

"The approval does not authorize the text. It authorizes the executor. When the executor differs from the originator, the approval must name the executor — or it authorizes nothing."
