PolicyStrata Paper and Artifact Kit

PolicyStrata is public as a paper PDF, reproducible artifact kit, and GitHub release. The artifact targets cross-layer policy drift in LLM data-agent stacks: manifest exposure, semantic validation, compiler lowering, database containment, lineage, and release checks.

The paper result is a deterministic artifact-suite result, not a production recall claim and not an authorization boundary. The current reproduction run emits 1800 traces, catches 1720 out of 1720 non-clean cases, and reports 0 false positives across 80 clean controls.

The public PDF is posted at /papers/PolicyStrata.pdf. The submission kit includes the public and anonymous PDFs, artifact reviewer guide, reproduce scripts, expected outputs, demo materials, and tool-demo paper. The GitHub release asset is the canonical downloadable copy; the website also mirrors it at /artifacts/policystrata/policystrata-submission-kit-2026-06-26.zip.

The deterministic reproduction path does not require an LLM API key or host psql. Docker is optional for database smoke checks.

git clone https://github.com/raintree-technology/policystrata.git
cd policystrata

A checked run produced the paper-facing counts: 1800 traces, 1720/1720 non-clean cases, 80 clean controls, 1720 minimized witnesses, median witness size 3302 bytes, and a 17M run directory.

Release notes and the artifact zip are also attached to the GitHub release.
