SENTINEL.

On-device security posture, privacy enforcement, and cyber defence under hardware-bound keys.

What this brain does

SENTINEL is the security specialist of the Mickai cooperative. It monitors the operator's surface area, enforces privacy boundaries across tenants (patent 04), inspects every inbound artefact for prompt injection and exfiltration patterns, and gates sensitive actions behind voice-biometric re-authentication (patent 13). Its threat model assumes the cloud is hostile and the network is observed; everything SENTINEL evaluates is verified against signed local policy, not against vendor reputation.

Responsibilities
Knowledge sources

Authoritative external corpora and standards this brain treats as canonical. Every retrieval against these sources is signed into the audit ledger so a regulator can prove which evidence drove which output.

Cloned tooling

Mickai-native tooling primitives this brain implements internally. Codex for sovereign plain-text graph PKM, Lectern for spaced-repetition memory, Stele for citation-provenance, and domain-native primitives layered on top. No external services in the trust path; data stays on operator-personalised hardware.
