Opis
- Own the access layer across native connectors, MCP servers, and Databricks in the US and EU.
- Enforce short-lived tokens, least-privilege read-only access, zero raw PII exposure, and data residency.
- Define versioned schemas for signed credentials and action records.
- Set up deployment pipelines, policy-as-code for authority, skill merge gates, signed builds, and software bills of materials.
- Build an authority lease service with integrated kill switches.
- Record events in append-only, hash-chained logs to support tamper-evident, independently verifiable audits.
- Move existing agents onto the Core and launch agents for new departments.
- Lead security reviews for continuous read access.
- Extend the Core to bounded write operations, with logged actions, idempotency keys, compensating actions, and multi-approver time locks for money movement.
- Design cross-institution interoperability primitives based on signed mandates, scoped authority, and attestation receipts.
- Design self-hosted, zero-egress private stacks when classification evidence requires them.
- Track developments in agent frameworks, confidential inference, and zero-knowledge attestations.
- Threat-model prompt injection, credential exfiltration, and confused-deputy risks.

- Security-first practices in a regulated setting, such as an MSB/VASP, bank, or comparable environment.
- Use least privilege and read-only access as standard practices.
