PRISM: Deterministic Control Plane for Document Changes

[Vishwak-8055]

PRISM — Evidence-Driven Document Change Intelligence

Built and engineered by Vishwak.

PRISM is a self-contained SuperDocs use case for making document changes observable, classifiable, reviewable, and verifiable rather than treating an edit as an opaque text transformation.

It builds structured document snapshots, identifies and classifies changes, evaluates them through an approval-aware gate, and provides comparison and verification workflows backed by reproducible fixtures and tests.

What it brings

• Document snapshots — deterministic representations of DOCX structure and content
• Precise change classification — distinguishes meaningful document changes instead of relying on raw text diffs alone
• Approval-aware application — separates proposed changes from authorized application
• Evidence-oriented verification — makes the resulting change state inspectable
• Document and table comparison — exposes structural and content-level differences
• Reproducible fixtures — deterministic sample documents for repeatable evaluation
• Interactive review UI — makes the change intelligence workflow directly inspectable
• Engineering documentation — architecture, fidelity, security, risks, testing, reproducibility, decisions, and known limitations

Engineering approach

PRISM is intentionally structured as a modular pipeline so that document representation, change analysis, approval, verification, and presentation remain independently testable.

The implementation favors deterministic evidence and explicit boundaries over opaque claims, and documents what is implemented, what is intentionally scoped out, and where the current limitations are.

Validation

The project includes automated tests, reproducible fixtures, and dedicated documentation for testing, security, fidelity, risks, and reproducibility.
