- Implemented comprehensive tests for verdict artifact generation to ensure deterministic outputs across various scenarios, including identical inputs, parallel execution, and change ordering.
- Created helper methods for generating sample verdict inputs and computing canonical hashes.
- Added tests to validate the stability of canonical hashes, proof spine ordering, and summary statistics.
- Introduced a new PowerShell script to update SHA256 sums for files, ensuring accurate hash generation and file integrity checks.
- Created `StellaOps.TestKit.Tests` project for unit tests related to determinism.
- Implemented `DeterminismManifestTests` to validate deterministic output for canonical bytes and strings, file read/write operations, and error handling for invalid schema versions.
- Added `SbomDeterminismTests` to ensure identical inputs produce consistent SBOMs across SPDX 3.0.1 and CycloneDX 1.6/1.7 formats, including parallel execution tests.
- Updated project references in `StellaOps.Integration.Determinism` to include the new determinism testing library.
Introduces new marketing bridge documents for Decision Capsules, Hybrid Reachability, and Evidence-Linked VEX. Updates product vision, README, key features, moat, reachability, and VEX consensus docs to reflect four differentiating capabilities: signed reachability (hybrid static/runtime), deterministic replay, explainable policy with evidence-linked VEX, and sovereign/offline operation. All scan decisions are now described as sealed, reproducible, and audit-grade, with explicit handling of 'Unknown' states and hybrid reachability evidence.
