Canonical S1–S11 security rule reference cited from AGENTS.md § Security Mandate. Load for plan/qa/compliance/do touching shipped artefacts.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Security Baseline (S1–S11)

> **Authority:** RFC 2119 keywords (MUST / MUST NOT / SHOULD / MAY) apply throughout this document.
> **Origin:** corporate security audit, 2026-04-28 — full audit log kept in the maintainer's workspace (`documentation/archive/security/findings-2026-04-28.md`). Research baseline: an OSS CLI security research note of the same date (maintainer-private).
> **Companion skills:** [`skills/security/SKILL.md`](../security/SKILL.md) (operational recipes — git history scrub, Tailscale+VPN coexistence, recon-vs-compromise heuristics, cross-stack relative-path includes) and [`skills/release-verify/SKILL.md`](../release-verify/SKILL.md) (S4 consumer-side verify entry point).
> **CI baseline:** [`tests/security/baseline.json`](../../tests/security/baseline.json) — machine-readable suppressions registry + required-jobs status.
> **Standards mapping:** [`documentation/reference/standards-mapping.md`](../../documentation/reference/standards-mapping.md) (S8 — full ASVS / SOC 2 / ISO 27001 / CIS table).

How to install

The exact contents, by fingerprint
mdr add arcanada-one/datarim/security-baseline@sha256:87de59a649b5a619

The line at the top of this page pins the label git:20261018.b63e9f8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
