- Introduced a new document outlining the inline DSSE provenance for SBOM, VEX, scan, and derived events. - Defined the Mongo schema for event patches, including key fields for provenance and trust verification. - Documented the write path for ingesting provenance metadata and backfilling historical events. - Created CI/CD snippets for uploading DSSE attestations and generating provenance metadata. - Established Mongo indexes for efficient provenance queries and provided query recipes for various use cases. - Outlined policy gates for managing VEX decisions based on provenance verification. - Included UI nudges for displaying provenance information and implementation tasks for future enhancements. --- Implement reachability lattice and scoring model - Developed a comprehensive document detailing the reachability lattice and scoring model. - Defined core types for reachability states, evidence, and mitigations with corresponding C# models. - Established a scoring policy with base score contributions from various evidence classes. - Mapped reachability states to VEX gates and provided a clear overview of evidence sources. - Documented the event graph schema for persisting reachability data in MongoDB. - Outlined the integration of runtime probes for evidence collection and defined a roadmap for future tasks. --- Introduce uncertainty states and entropy scoring - Created a draft document for tracking uncertainty states and their impact on risk scoring. - Defined core uncertainty states with associated entropy values and evidence requirements. - Established a schema for storing uncertainty states alongside findings. - Documented the risk score calculation incorporating uncertainty and its effect on final risk assessments. - Provided policy guidelines for handling uncertainty in decision-making processes. - Outlined UI guidelines for displaying uncertainty information and suggested remediation actions. --- Add Ruby package inventory management - Implemented Ruby package inventory management with corresponding data models and storage mechanisms. - Created C# records for Ruby package inventory, artifacts, provenance, and runtime details. - Developed a repository for managing Ruby package inventory documents in MongoDB. - Implemented a service for storing and retrieving Ruby package inventories. - Added unit tests for the Ruby package inventory store to ensure functionality and data integrity.
Stella Ops Bench Repository
Status: Draft — aligns with
docs/benchmarks/vex-evidence-playbook.md(Sprint 401).
Purpose: Host reproducible VEX decisions and comparison data that prove Stella Ops’ signal quality vs. baseline scanners.
