PROJECT INTELLIGENCE
Overview
PROJECT CONTEXT
Project brief
Lumen is a high-assurance authentication and identity microservice engineered for zero-trust architecture. It provides TOTP multi-factor authentication (RFC 6238), cryptographic session rotation using signed JWT pairs, Redis-backed revocation caches, and GitHub/Google OAuth2 federation with automated validation pipelines.
Inspect full verified context specifications
Architecture Invariants:
- All cryptographic operations must use constant-time comparisons (prevent timing side-channels).
- Session tokens must rotate on every privileged state transition (e.g. password change, MFA verification).
- All database queries must execute with parameterized statements through resilient connection pools.
