Riverbraid Evaluation Kit v0.1.0 governance floor

This kit is a scaffold for independent reproduction of Riverbraid's verified governance floor. It is designed to fail closed.

Role in Riverbraid

Riverbraid-Evaluation-Kit is the current public entry and evaluation surface for Riverbraid.

Public verification boundary

This repository defines the current public canonical verification registry and reproduction path for Riverbraid's governance floor.

Evidence boundary

This repository does not claim certification, legal approval, production readiness, absolute security, external audit, complete AI safety, adoption, or absence of defects.

Verification Paths

Preferred: GitHub Actions (Canonical, No Local Setup Required)

The primary verification path runs on ubuntu-latest in GitHub Actions.

Steps:

1. Navigate to this repository's Actions tab
2. Select Riverbraid Evaluation Kit Runtime
3. Click Run workflow button
4. View the verification summary when complete

What happens:

• All 16 required files are verified present
• verified-repo-registry.json is validated: exactly 30 entries, all pinned, all valid commits
• Docker image is built from Dockerfile
• Docker container runs the full verification suite
• Each of 30 repositories is cloned at its pinned commit
• Each verification command runs
• Results are compared against expected-results.json
• Final JSON summary shows verification status

Result: If all checks pass, the workflow emits:

{
  "status": "GITHUB_ACTIONS_RUNTIME_VERIFICATION_PASS",
  "runtime_claim": "EXECUTED_IN_GITHUB_ACTIONS",
  "docker_claim": "VERIFIED_IN_GITHUB_ACTIONS",
  "verification_surface": "ubuntu-latest GitHub Actions",
  "local_windows_claim": "NOT_REQUIRED"
}

Optional: Local Docker (Only If Docker Already Installed)

If Docker is already working on your machine, you may also reproduce locally:

docker build -t riverbraid-evaluator .
docker run --rm riverbraid-evaluator

Important: Do not install Docker as a first step. GitHub Actions is the canonical verification path.

Current State

Aspect	Status
Registry entries	30
Commit state	All pinned
Claim level target	Independent reproduction
Canonical verification surface	GitHub Actions on ubuntu-latest
Local Docker requirement	Optional
Windows Docker requirement	Not required

What a PASS Means

A PASS means:

• The pinned registry was successfully cloned at exact commits
• Each configured verification command executed and produced no errors
• The final summary matched expected-results.json
• Reproduction is deterministic and repeatable in the specified environment

What a PASS Does NOT Mean

A PASS does not mean:

• The system is defect-free or bug-free
• The system is production-safe or deployment-ready
• The system is certified by any authority
• The system is externally audited or independently reviewed
• The system is suitable for any specific risk profile
• The system is compliant with any regulation or standard
• The system is safe in all deployment contexts
• Any claim about downstream AI system behavior

Non-Claims

This evaluation kit explicitly does not:

• Certify AI systems or models
• Provide legal approval, compliance certification, or liability protection
• Replace security review, legal review, or compliance audit
• Guarantee safety, defect-freeness, or production readiness
• Make any claims about the behavior of systems that use this as a component
• Constitute an external audit or third-party assurance
