Proof of determinism in the browser
Tests reproducibility, tamper-evidence
These tests are intentionally simple: they validate the core promise of the Sandbox. Same input → same output, stable extraction of basic anchors, and reproducible sha256 integrity anchors.
Important: passing these tests does not mean “truth”. It means the pipeline is deterministic and auditable.
