FACTOS
Demonstration environment. This record describes synthetic instruments on Ethereum Sepolia. It does not represent a real credit right or a real person. The registry state below is written by a single FACTOS key.

REGISTRY-STATE REFERENCE

FACTOS-PRS-2026-09-10

A mandate bound to one specific right. The authority is scoped to a single instrument by the mandate itself, so the mandate registry refuses the wrong instrument before any compliance logic of ours is reached. Built at the request of the ERC-8226 author.

What it demonstrates

An ERC-8226 mandate names an asset, which is a contract address, and a contract can hold many rights. The action field is a bytes32 label, and an implementation may bind selected call parameters into it rather than using a bare function selector. Here the label is computed per instrument, so a mandate granted over instrument 1 carries no authority over instrument 2.

What separates the two instruments, and what does not

Both instrument 1 and instrument 2 were published as current in the FACTOS registry, with the same holder. Registry state is therefore not what separates them. Neither is identity: the same agent, the same holder, the same asset and the same mandate are in play. The only difference is the action label the mandate enumerates.

Instrument 1canExecute answers (true, OK) · the agent acts
Instrument 2canExecute answers (false, 6) · the operation reverts with NoMandate(agent, 6)

Check it without asking us

Use an archive endpoint. The two commands below read state at a past block. Most public Sepolia nodes prune historical state and will answer state at block … is pruned rather than the result. Any archive endpoint works; https://sepolia.gateway.tenderly.co is one. This is the same trap that made our own test suite pass only on the machine that had already cached the data.

What this does not cover

A parameter-scoped action binds the mandate to an instrument at the moment it is granted, and that binding is static. It says nothing about whether the right still exists, or whether the holder is still the holder, at the moment the agent acts. Those are answered by the registry read in FACTOS-PRS-2026-09-08. The two controls sit at different moments and neither replaces the other.

We also reported that reason code 6, ACTION_NOT_ENABLED, reads as though the operation were forbidden when in fact it is permitted on a different object. That reading was answered in the thread and the answer is better than ours: because the action label is opaque to the mandate registry, the registry cannot know which part of the label failed to match, so the correct fix is to define the existing code precisely rather than to add another one.

Scope of what is published. Synthetic instruments on a test network, written by a single FACTOS key. What is published is a measured fact, never a recommendation. It does not certify that a right is valid or enforceable in any given forum, nor the authenticity of the identity binding of the parties.
