- Added IIssuerDirectory interface for managing VEX document issuers, including methods for registration, revocation, and trust validation. - Created InMemoryIssuerDirectory class as an in-memory implementation of IIssuerDirectory for testing and single-instance deployments. - Introduced ISignatureVerifier interface for verifying signatures on VEX documents, with support for multiple signature formats. - Developed SignatureVerifier class as the default implementation of ISignatureVerifier, allowing extensibility for different signature formats. - Implemented handlers for DSSE and JWS signature formats, including methods for verification and signature extraction. - Defined various records and enums for issuer and signature metadata, enhancing the structure and clarity of the verification process.
StellaOps Policy Engine
Policy Engine compiles and evaluates Stella DSL policies deterministically, producing explainable findings with full provenance.
Responsibilities
- Compile
stella-dsl@1packs into executable graphs. - Join advisories, VEX evidence, and SBOM inventories to derive effective findings.
- Expose simulation and diff APIs for UI/CLI workflows.
- Emit change-stream driven events for Notify/Scheduler integrations.
Key components
StellaOps.Policy.Engineservice host.- Shared libraries under
StellaOps.Policy.*for evaluation, storage, DSL tooling.
Integrations & dependencies
- MongoDB findings collections, RustFS explain bundles.
- Scheduler for incremental re-evaluation triggers.
- CLI/UI for policy authoring and runs.
