zero▌

Configures mutual TLS (mTLS) authentication between microservices using Python cryptography library for certificate generation and ssl module for TLS verification. Validates certificate chains, checks expiration, and audits mTLS deployment status. Use when implementing zero-trust service-to-service authentication.

Implement comprehensive Zero Trust security architecture based on "never trust, always verify" principle with identity-centric security, microsegmentation, and continuous verification.

Layer 1: Language Mechanics

Compile-time versus runtime polymorphism: generics, trait objects, and zero-cost abstraction patterns. \n \n Distinguishes static dispatch (generics, impl Trait ) from dynamic dispatch ( dyn Trait ), with decision guidance on when each is appropriate based on type knowledge, performance priorities, and collection heterogeneity \n Maps common type system errors (E0277, E0308, E0599, E0038) to underlying design questions rather than mechanical fixes \n Covers object safety constraints, monomorphiz
