Local DoD (short)

# Run all quality gates
nox -s lint typecheck tests gates
# Run tests with coverage
pytest --cov=src --cov-fail-under=90
# Validate status schema
pytest -q tests/status/test_example_report_schema.py
# Validate configs
python tools/validate_configs.py --root configs/training --schema configs/schemas/training.schema.yaml

Local Gates & Status Reports

This repository ships local-only quality gates (no CI) and a local status reporter:

• See docs/ops/local_gates.md for running fences, evaluator, schema checks, and the selection guard.
• See docs/ops/status_reports.md for generating a reusable STATUS_REPORT.md (including template mode, --verbose, and --save-logs). Quick start:

python tools/status_report.py --summary samples/assistant_message_summary.sample.json --selected 3 --out STATUS_REPORT.md
```text
### repository Status Audit
Generate a comprehensive status update audit report for the Codex repository:
```bash
# Generate JSON status update (new schema-based generator)
codex-status-audit --generate
# Output: .codex/status/_codex_status_update-YYYY-MM-DD.json
# Or use the direct script
python tools/generate_status_update.py
# Full audit and report (legacy)
codex-status-audit
# Quick regeneration with existing artifacts
codex-status-audit --skip-audit
# Compare against baseline
codex-status-audit --baseline audit_artifacts/capabilities_scored.json.baseline
```text
The new JSON-based status update generator provides:
- Automated repository analysis
- 8 capability checks with gap analysis
- Reproducibility controls audit
- Test infrastructure status
- Security assessment
- Schema validation (v1.2)
See **[tools/README_status_update.md](tools/README_status_update.md)** for the new generator documentation.
See **[docs/cli/status_audit.md](docs/cli/status_audit.md)** for legacy audit tool usage.
## Candidate Selection (local-only)
You can generate a local selection recommendation across 1–4 assistant variants:
```bash
python tools/selection_report.py \ --summary samples/assistant_message_summary.sample.json \ --out SELECTION_REPORT.md
```text
This runs the evaluator and enforces required selection-guard signals, then explains the tie-break.

## Building Docker images locally
To reproduce the CI image builds locally (recommended to use linux/amd64 platform to match published wheels):
- CPU image:
```bash
docker build --platform=linux/amd64 -f Dockerfile -t codex-ml:cpu-local .

• GPU image (requires NVIDIA container toolkit and compatible CUDA runtime):

docker build --platform=linux/amd64 -f Dockerfile.gpu -t codex-ml:gpu-local .

Notes:

• If you set ALLOW_MULTIARCH to true in the workflow, CI will attempt arm64 builds; ensure that required Python wheels exist for that platform.

Build cache and per-arch wheels

• The Dockerfiles use BuildKit cache mounts to speed up Python package downloads:
• Ensure BuildKit is enabled (default on GitHub Actions; locally: export DOCKER_BUILDKIT=1).
• CI uses docker/build-push-action cache-to/cache-from to reuse layers across runs.
• Per-arch wheel builds:
• The workflow uploads wheelhouse artifacts for each enabled platform (amd64 always; arm64 only when ALLOW_MULTIARCH='true').
• Review artifacts in the Actions run to validate wheel availability on each platform before enabling multi-arch pushes.

Supply Chain Security & Dependency Management

Wheel Manifest & Baseline Artifacts

The CI pipeline generates cryptographic manifests of all Python wheels built during the image build process:

• Manifest Generation: Each wheel build produces a manifest.json with SHA256 hashes
• Per-Platform Baselines: Separate manifests for linux/amd64 and linux/arm64 (when enabled)
• Artifact Storage: Manifests uploaded to GitHub Actions artifacts for 30-90 iterations Generate a local manifest:

python scripts/ci/generate_wheel_manifest.py \ --wheelhouse ./wheelhouse \ --output manifest.json \ --platform linux/amd64 \ --python-version 3.11

SBOM (Software Bill of Materials)

Every PR build generates SBOM files in multiple formats:

• SPDX JSON: Industry-standard format for license compliance
• CycloneDX JSON: OWASP standard for security analysis
• Syft JSON: Anchore-native format with rich metadata SBOMs are automatically:
• Generated for both CPU and GPU images
• Scanned with Grype for known vulnerabilities
• Uploaded to GitHub Security tab (SARIF format)
• Stored as workflow artifacts

Scheduled Dependency Audit

per-phase automated audit workflow (scheduled-dependency-audit.yml) runs:

1. Baseline Regeneration: Rebuild wheelhouse and manifests
2. Drift Detection: Compare with previous baseline, alert on changes
3. SBOM Scanning: Generate and scan SBOMs for vulnerabilities
4. Upgrade Compatibility: Test Python 3.12, 3.12, 3.13 compatibility
5. Issue Creation: Auto-file GitHub issues when drift detected Trigger manually:

gh workflow run scheduled-dependency-audit.yml \ -f python_version=3.12 \ -f enable_multiarch=true

Upgrade Strategy

Scenario	Action	Trigger
Ray publishes 3.12 wheels	Test in shadow matrix	per-phase audit detects availability
Hash mismatch detected	Review manifest diff, update pins	Drift detection alerts
CVE in dependency	Review Grype SARIF, patch/upgrade	Security scan on PR
Multi-arch expansion	Enable ALLOW_MULTIARCH=true, verify artifacts	Manual testing then repo variable
Python minor upgrade	Run upgrade-compatibility job, fix issues	Scheduled audit tests new versions

Security Posture

• All wheels integrity-verified via SHA256 manifest
• SBOM generation on every PR build
• Vulnerability scanning with Grype (critical = fail)
• per-phase dependency drift detection
• Automated Python version compatibility testing
• GitHub Security integration for SARIF alerts

Security Utilities

New in v2.0: Comprehensive security utilities for sensitive data handling.

Quick Start

from codex.security import mask_token, sanitize_log, hash_secure # pragma: allowlist secret
from codex.security.storage import SecureStorage
# Mask sensitive data in logs
logger.info(f"API Key: {mask_token(api_key)}") # pragma: allowlist secret
# Output: "API Key: ****************xyz789"
# Prevent log injection attacks
user_input = request.form.get('data')
logger.info(f"User provided: {sanitize_log(user_input)}")
# Secure token hashing for comparison # pragma: allowlist secret
token_hash = hash_secure(token, algorithm='sha256') # pragma: allowlist secret
# Encrypted storage for secrets # pragma: allowlist secret
storage = SecureStorage() # Requires ENCRYPTION_KEY env var
storage.store_secret("secrets/api_key.enc", api_key) # pragma: allowlist secret
api_key = storage.load_secret("secrets/api_key.enc") # pragma: allowlist secret

Performance

All security functions are highly optimized for production use:

Function	Throughput	Use Case
mask_token()	3.7M ops/sec	API key masking
mask_password()	12.4M ops/sec	Password hiding
sanitize_log()	1.3M ops/sec	Log injection prevention
hash_secure()	1.2M ops/sec	SHA-256 token hashing
Benchmark Results: All functions <0.01ms average (see benchmarks/security_benchmarks.py)
