Every crate in the AEGIS workspace, what it does, and how it fits together.
openagent-aegis-core
1.8K LOC
Core types, traits, and error hierarchy. Defines VerificationPipeline, AuthProvider, and PolicyEngine trait interfaces.
aegis-keys
2.1K LOC
Ed25519 key management with HKDF derivation, BIP-44/SLIP-0010 paths, FROST group key support, and AES-256-GCM encryption at rest.
aegis-auth
1.6K LOC
Challenge-response authentication with pluggable providers. Session token management with configurable TTLs.
aegis-verify
2.3K LOC
7-step verification pipeline: resolve → schema validate → signature verify → revocation check → lineage chain → liveness → conformance.
openagent-aegis-policy
1.9K LOC
Multi-dimensional policy engine with spending limits, temporal windows, lineage constraints, and contract-based policies.
aegis-delegate
1.4K LOC
Hierarchical delegation with anti-amplification rule — children cannot exceed parent permissions. Scope narrowing only.
