Small problems.
System-level consequences.

RISU Institute develops and tests small, reusable ideas at the boundaries of law, technology, standards, and institutional design.

We prefer narrow claims, executable tests, and artifacts that can survive contact with existing systems.

Featured work

A shared purpose identity for requesting review of a prior decision.

Experimental semantic · 2026

Appeal

Can a generic client recognize that an affordance is for requesting review or reconsideration without learning every provider’s vocabulary?

Appeal is a carrier-neutral semantic identity for that purpose. Its first experimental Web Linking binding uses an RFC 8288 extension relation URI controlled by RISU Institute.

Method

Make the claim smaller until it becomes hard to break.

Start narrow

Prefer the smallest reusable semantic or mechanism over a new platform.

Attack boundaries

Separate purpose from authorization, trust, execution, timing, and legal entitlement.

Test executable claims

Use adversarial fixtures and frozen consumers where code can falsify the idea.

Publish what survives

Do not turn an experiment into a standard before independent use earns that claim.
