<div class="section-label">02 · The gap</div>
<h2>Your systems record what was decided.<br/>Nothing records what was authorised.</h2>
<p class="section-intro">
Every institution deploying agents already has two systems that look like they cover this. Neither one does, and neither can stop the other.
</p>
<div class="gap-pair">
<div class="gap-cell">
<h3>What you have · the decision log</h3>
<p>Your application writes down what the agent did and when. It is a record produced after the fact, by the same system that took the action, and it can be reconstructed, backfilled, or simply be wrong. It answers <em>what happened</em>. It cannot answer whether the thing that happened was permitted.</p>
</div>
<div class="gap-cell">
<h3>What you have · the payment record</h3>
<p>Your rail writes down that value moved. It is authoritative about settlement and silent about everything before it. By the time the instruction reaches the rail the decision is already made, and on the instant rails there is no state left in which it can be recalled.</p>
</div>
</div>
<div class="gap-pair" style="margin-top:1px;">
<div class="gap-cell absent" style="grid-column: 1 / -1;">
<h3>What nothing records · the authority</h3>
<p>Which human granted this machine the right to act, bounded how, for how long, and against which counterparties. That fact exists at the moment of delegation and nowhere afterwards. It is not in the decision log, because the log is written by the thing being constrained. It is not in the payment record, because the rail never saw it. When a supervisor asks whether an agent acted inside its authority, there is no artifact to hand them.</p>

Two systems record two things, and neither one can stop the other. Observer Protocol records the third, and refuses before either of the other two is reached.

<h2>What refuses, and what proves.</h2>
<p class="section-intro">
Three artifacts. Each one is a signed object, each one is checkable by someone who does not trust us, and the second one is the primitive nothing else publishes.
</p>
<div class="prim-grid">
<div class="prim">
<div class="prim-num">01 · THE MANDATE</div>
<h3>Signed by the principal, out of the agent's reach.</h3>
<p>A credential the human signs, not the machine. It states a ceiling, a counterparty set, a window, and whether a decision must be cited before the action is permitted. The agent holds a key that can spend inside it and no key that can widen it. Rewriting the mandate is not a permission the agent has to escalate to; it is a signature it cannot produce.</p>
</div>
<div class="prim">
<div class="prim-num">02 · THE REFUSAL</div>
<h3>A request outside mandate produces no instruction.</h3>
<p>Not a warning. Not a flag on a dashboard for someone to review on Monday. No instruction is emitted, so there is nothing downstream to recall, reverse, or dispute. The check fails closed: if the mandate cannot be read, or the revocation status cannot be established, the answer is no. And the refusal is itself a signed record, which is the part nobody else publishes.</p>
</div>
<!-- ==========================================================================
REVIEWER: DO NOT ATTACH A QUALIFIER TO "A determination is independently
verifiable by a party who was not there."
It is flat on purpose. The two limits a reader thinks of next are both
real and both are in the register in section 08, as separate rows:
determination records written before the document bytes were kept are
not reconstructible, and no public surface exists for an outsider to
run the check.
Neither narrows this sentence. The first is about which records exist,
the second is about who has been handed a tool, and this sentence is
about what a determination in your hands is worth. Hedging it here
would trade a measured property for the appearance of caution: the
artifact is verify-samples/ppp-determination-refused-outcome.json, the
call is verifyDecisionAttestation, and verify-published-credentials.mjs
runs it in CI on every build.
If this tile has to be shortened, cut the opening sentence listing what
the attestation carries. Keep this one, and keep the set that follows it.

A successful payment demonstrates that a system can move money. It says nothing about whether the system could have stopped. So here is the other record: a payment that was requested, was fully fundable, had a route, and did not happen. One entry, on a live rail, with the money there.

<p><strong style="color:var(--text);">The payment could have succeeded.</strong> There was more than four times the balance required, a live channel to a well-connected peer, and a working node. Nothing about the network prevented it. The mandate did.</p>
<p>The control matters as much as the refusal. Ten sats to the same destination, over the same channel, by the same RPC method, settled. So the denial is the mandate acting on the amount, not a broken node, a closed channel, or a route that was never there. A refusal you cannot distinguish from a failure is not evidence of anything.</p>
<p>Stripping the caveat does not help: it dies on the macaroon HMAC chain. A hand-rolled gRPC client running as a different user with a sanctioned macaroon was refused by the node the same way, and the middleware defaults to deny across all 70 RPC methods and fails closed if it dies.</p>

<strong>What this entry does not show.</strong>
The mandate issuer was a demonstration <code>did:key</code>, not Observer Protocol's production issuer.
· One node, ours, so this is enforcement at a node and not closure of the Lightning network.
· The macaroon caveat is a sender-side trigger in the payer's own credential; it is not visible to the payee, who sees an HTLC and a preimage like any other payment.

SOURCE: what is verifiable without us, and the measurement behind it.
Corrected 2026-08-10. This previously said verifying a refusal end to end
was "currently something only we can do". That stopped being true at rc.9,
which exports the payload builder. rc.9 is a HISTORICAL reference here: it
names when the capability arrived and must not be updated to track the
lockfile, which is why it is written without a full version string.
THE RECONSTRUCTION: a scratch directory containing only
@observer-protocol/policy-engine at rc.9, with NO checkout of any
repository, rebuilt the signed payloads for all 14 refusals in the live
2026-08-08 corpus. 14 of 14 verify. 14 of 14 reject a one-field tamper.
Recorded in op-at-specs/HANDOVER-2026-08-08-rc9-wiring-and-control-repairs.md.
The "no checkout" part is the whole point: it is a counterparty proof, not a
parity test that works because two repos sit adjacent on one machine.
WIDENED 2026-08-17, and the list is now delegation credentials, refusal
records, lapse records and decision attestations. Widen it again only on a
measurement, and record the measurement here.
WHAT WAS MEASURED FOR THE DECISION ATTESTATION, on 2026-08-17, against the
version npm's latest tag serves: verify-samples/ppp-determination-refused-outcome.json
is a published op.decision.attestation record, and
scripts/verify-published-credentials.mjs returns allow=true on it through
verifyDecisionAttestation, which every published tarball from rc.8 to rc.19
exports. The record carries the wire document as base64 with a documentHash of
sha256:b6c0bdd0, and sha256 over those stored bytes reproduces that hash, so the
input to the signature can be rebuilt from the record by someone holding nothing
else. rc.8, rc.12 and rc.19 are HISTORICAL references here and are written
without a full version string, for the same reason rc.9 is above.
A PolicyEvaluationCredential IS STILL EXCLUDED and is a DIFFERENT ARTIFACT
from a decision attestation: both published PECs still fail with
PEC-NO-VERIFIER-PATH in the same CI check. Conflating the two is the error the
previous correction removed and this one keeps removed. Resolutions, instructions
and releases are also still excluded; resolutionPayload is absent from rc.9
through rc.12 and section 02 of /verify carries that band.
