Flagship assurance software · v0.4.0-rc1 research release

Consequence assurance
for machine action.

A tool can keep the same name, inputs, and shape while losing a safeguard that changes what an action actually does. RISU Verify checks whether that consequence-defining safeguard survived the projection.

The result is not just a pass or fail. RISU carries the declared source consequence, bounded evidence, proof-carrying certificate, run identity, and browser-checkable handoff as one assurance record.

Research frontier · October 2026

From bounded execution to independently checked refinement.

RISU Verify now extends its bounded-execution assurance path into one deliberately narrow mediated-refinement lane. A richer finite-state source is independently interpreted, lowered into the already-qualified bounded model, replayed across independent implementations, and checked again downstream before a preservation result can survive.

The candidate has passed pre-implementation adversarial oracles, large-scale generative and differential testing, an orthogonal reference evaluator, and independently checked refinement-certificate qualification. This remains a research checkpoint, not a new general-purpose release or a production proof kind.

Bounded preservationIndependent checkers reconstruct the complete realized consequence relation.
Narrow refinement candidateA bounded finite-state source → qualified execution path has survived crossed, generative, orthogonal-reference, and certificate gates.
Still openProduction authority and unrestricted native-software refinement remain out of scope.

The gap RISU checks

Surface compatibility is not consequence preservation.

Ordinary interface checks can tell you that a tool still exists and that its schema still matches. RISU asks the next question: does the distinction that was supposed to control the effect still control it?

Interface layerSame action name · same parameters · same response shape
Operational layerThe safeguard may still have moved, disappeared, or stopped gating the effect.

One assurance record

From declared consequence to inspectable evidence.

01Source contract

State the consequence that must survive.

02Projection adapter

Bind the target operation and evidence.

03Frozen core

Evaluate C, D, O and exact realization.

04Certificate

Carry the proof-linked assurance result.

05Run handoff

Package exact result bytes for CI or review.

06Workbench

Rehash, cross-check, compare, and inspect locally.

Published external evidence

Different systems. One consequence question.

REGRESSIONGitHub guarded merge · reviewed head SHA

Represented, but not operative.

The reviewed head can remain visible and distinguishable while failing to gate the consequential merge.

C1 · D1 · O0
PRESERVEDAzure Wiki edit · ETag / If-Match

The reviewed version still controls the write.

A matching ETag commits. A changed page rejects the stale edit under the declared bounded model.

C1 · D1 · O1
REAL HISTORICAL TRANSITIONGitHub file update · blob SHA

Before regression. After repair.

The same declared source semantics are evaluated across an independently developed upstream change.

C0 / NA / NA → C1 / D1 / O1

Record identity

Readable for people. Traceable for engineers.

A general reader can stop at the consequence verdict. An engineer can continue into bounded worlds, C/D/O, exact realization, certificate bindings, source semantic digest, provenance, and release identity without switching to a different story.

Research progression

Closure → Projection → Verification.

Consequence ClosureWhat must be known?

Determine the semantic obligations needed before consequential action is fixed.

Projection AssuranceDid the distinction survive?

Check whether the consequence-relevant distinction remains represented and operative after projection.

RISU VerifyMake it executable.

Turn those commitments into reproducible assurance records, CI signals, witnesses, and portable review artifacts.

Analyze an assurance record

Open one RISU run.

Drop a portable .risu.json handoff from CLI or CI. The Workbench independently rehashes its embedded artifacts, recomputes report-level consequence logic, and checks the report, certificate, and run manifest against one another.

Drop a RISU assurance record

Preferred: one .risu.json. Advanced: select report.json, certificate.json, run-manifest.json, and optional supporting artifacts.

Compare assurance records

See exactly what changed.

Open one .risu-compare.json, or select two .risu.json run records. RISU only labels the comparison “same declared source semantics” when both records carry the identical source semantic digest.

Drop a comparison or two run records

Use comparison to isolate a projection change without silently changing the source consequence being asked about.
