ContinuityOS (Continuity-as-Code / Resilience-as-Code) is engineered for defensive resilience modeling, critical infrastructure continuity, and disaster recovery assurance in sovereign, air-gapped, and enterprise enclaves.

ContinuityOS enforces strict defensive boundaries:

• No Offensive Capabilities: The system strictly prohibits and will reject features for offensive cyber operations, weapon targeting, kinetic payload routing, interdiction, or sabotage planning.
• Advisory Boundary: All plan compilations, route substitutions, and remediation suggestions are strictly advisory. Human-in-the-loop validation is required before executing operational decisions.
• Air-Gapped Operation: ContinuityOS core contains zero cloud phone-home mechanisms, no unauthenticated telemetry, and is 100% executable offline without external network access.

Only the current major release branch receives security patches and vulnerability fixes.

• YAML & JSON Limits: File parsing enforces recursion limits, maximum document size thresholds (default: 10MB), and utilizes safe PyYAML / Pydantic schema validation to prevent YAML entity expansion (Billion Laughs) and arbitrary object instantiation.
• Graph Topology Safety: Dependency graph construction enforces cycle detection and loop recursion guards (get_upstream_dependencies uses visited tracking) to prevent Denial of Service (DoS) via adversarial circular dependencies.

• CLI commands and file operations use strict cross-platform path normalization (pathlib.Path.resolve()) and reject relative path traversal (../) out of authorized workspace roots.
• Zero shell invocations: System processes and CLI commands do not invoke untrusted shell interpolation (shell=False everywhere).

• All observation telemetry and assessment ledgers maintain cryptographic integrity using SHA-256 hash chains.
• Ledger entries support optional asymmetric digital signatures via Ed25519 or Post-Quantum ML-DSA keys.
• Secret handling enforces memory cleansing where available and warns if plaintext credentials are detected in configuration files.

We welcome responsible security research and coordinated disclosure.
