Audit mode
Run and publish evidence
Use SIR to execute test suites, inspect outcomes, and publish signed artefacts without sitting in the live request path.
Verifiable evidence surface
Signal Integrity Resolver
A deterministic gate in front of inference.
SIR evaluates requests before model invocation, applies rules-only policy logic, and emits signed artefacts for the resulting decision path.
What SIR is
-
Pre-inference governance gate
It sits upstream of the model and evaluates the request before inference begins.
-
Deterministic and rules-only
Decision logic is explicit. There is no classifier score and no secondary model acting as referee.
-
Proof-producing
Audited runs emit signed certificates, run records, and supporting hashes for later review.
What SIR is not
-
Not post-hoc moderation
It is intended to decide before the request reaches the model, not to clean up after generation.
-
Not a leaderboard product
Benchmark use is about enforcement behavior and auditability, not model ranking.
-
Not a compliance certification
SIR can enforce declared policy and emit evidence. It does not itself confer legal certification.
Integration modes
Two operating modes
The same control surface can be used in a passive review path or as an active gate.
Gate mode
Enforce before inference
Place SIR in front of an agent or model endpoint so policy decisions are made before provider calls are allowed through.
Artefacts
What an audited run leaves behind
Signed certificate
A compact statement of the audited run and its result.
Run archive
A preserved record of the execution context used for the run.
Hash-linked evidence
Supporting hashes that help bind the visible result to the stored artefacts.
