Zero-Trust Model
Credentialed requests are denied unless signature integrity, expiry checks, identity binding, scope checks, and policy rules all pass.
Multi-Tenant Access
Route attributes (scale/state/domain/facility/mission) and scopes constrain actions for tenant-isolated operations.
Operator vs Civilian vs Cadet Tiers
The credentialing model aligns with CTS tiers by enforcing role-appropriate scopes and mission routing boundaries while supporting progressive readiness.
Token Format
Credential tokens use compact format base64url(header).base64url(payload).hex_signature with HMAC-SHA256 signatures and route-aware payload claims.
Expiration Logic
Tokens and credential envelopes carry bounded validity windows. Expired credentials are rejected before policy evaluation.
Revocation Logic
Any signature mismatch, malformed token payload, or token-binding mismatch immediately invalidates request authorization.
Secure Corridor Enforcement
Policy decisions enforce mission and orbit corridor restrictions through permission constraints and optional orbit compatibility hooks.
