Argus SDK

Argus SDK is Esthien's software entry point for profile-bound controller regression evaluation. It provides a Python API and the argus command-line interface for loading a declared trace, applying a declared fault corpus, and writing evidence records with explicit boundaries.

v0.7.4 status

0.7.4 is in controlled evaluation preparation. It is not available through a public download page or package index, and it must not be represented as a production-ready or generally available product. A locally built Windows x64 installer candidate exists for installation and uninstall verification only. It is unsigned and is not approved for distribution.

The release-validation plan covers these host tuples:

The host matrix is not an availability claim. No tuple is marked supported merely because an installation succeeds. A release candidate requires a recorded installation, CLI, Python API, regression-evaluation, and signing record for its specific tuple. Product approval remains separately gated.

Current evidence boundary

• The default evaluation path writes digital_source_verification evidence.
• Output source hashes provide integrity traceability. They are not release signatures or a safety certification.
• The SDK does not establish hardware timing, thermal, power, functional-safety certification, production silicon, or customer-system qualification.
• Measured-evidence classes require a separately controlled measurement record and are not asserted by v0.7.4.

Distribution boundary

The product distribution path exposes a deliberately narrow command surface. It does not claim source-code secrecy, package encryption, hardware binding, release signing, security certification, or production key custody. Those controls require separately approved technical and operational evidence.

Local development

Requirements:

• Python 3.11 or later
• A supported Python environment with NumPy, SciPy, and scikit-learn

python -m venv .venv
.\.venv\Scripts\Activate.ps1
python -m pip install --upgrade pip
python -m pip install ".[dev]"
argus --version
argus runtime-info
argus regression-eval --sample --out out\smoke

The default regression profile is packaged with the SDK, so the sample command works without relying on a source-tree-relative configuration path.

Python API

from argus import ConfidenceCoupledSafetyEnvelope, ProfileCompiler

compiler = ProfileCompiler()
envelope = ConfidenceCoupledSafetyEnvelope()

The public Python imports are versioned with the package. Product packages do not expose internal research, hardware-design, or roadmap material.

CLI

argus --version
argus runtime-info
argus regression-eval --sample --out <directory>
argus --help

runtime-info reports the detected host, the planned validation matrix, the Windows x64 installer-candidate scope, and the release-approval boundary.

Candidate-release build

The internal candidate builder creates a controlled wheel, dependency inventory, and a machine-readable release manifest. It does not create a public source archive, sign an artifact, or approve distribution. Native packages are built and validated per host tuple. Windows candidates use an application installer; macOS and Linux packages require their own native package and signing paths before they can be offered.

python -m pip install build==1.6.1
python scripts\build_release.py --out C:\temp\argus-sdk-release-candidate

Any distribution remains blocked until the required host tuple passes, the dependency inventory receives security review, the artifact is signed with an approved release key, and a release-approval record is complete.
