aevum-core
The independent black box for AI agents — tamper-evident, independently verifiable records of what your agents did.
aevum-core is the Aevum context kernel: five governed functions (ingest,
query, review, commit, replay) over an append-only episodic ledger,
gated by five unconditional barriers (crisis detection, classification
ceiling, consent, audit immutability, provenance) that are hardcoded and
never policy-controlled.
- SHA3-256 hash-chained sigchain — every event is RFC 8785 (JCS) canonicalized and Ed25519-signed (RFC 8032); an optional hybrid ML-DSA-65 (FIPS 204) signature runs alongside it for post-quantum defense-in-depth.
- COSE_Sign1 receipts with RFC 3161 trusted timestamps — each entry is wrapped in a portable, independently verifiable receipt.
- RFC 6962-style Merkle log — Signed Tree Heads with inclusion and consistency proofs detect any historical rewrite of the ledger.
- Cedar ABAC + OPA policy engines — consent and content/infrastructure decisions are externalised and optional, sitting behind the unconditional barriers rather than replacing them.
- Verification logic also ships as a separate package,
aevum-verify, so a receipt can be checked without running the rest of the kernel.
