# Continuous recertification & retirement

Scheduled and event-driven reassessment that renews, restricts, transfers, suspends, or ends an agent’s authority—and verifiably revokes its identities, credentials, tools, dependencies, and retained data at retirement.

## Definition

Scheduled and event-driven reassessment that renews, restricts, transfers, suspends, or ends an agent’s authority—and verifiably revokes its identities, credentials, tools, dependencies, and retained data at retirement. Production authorization decays as owners, models, data, tools, and operating conditions change.

Access recertification is established; complete agent product-lifecycle governance is still developing.

## Why it matters

Production authorization decays as owners, models, data, tools, and operating conditions change.

The operating shift is from “One-time launch approval” to “Expiring, continuously renewed authority.”

## System anatomy

- **Practice 1:** Require an owner heartbeat and authorization expiry
- **Practice 2:** Trigger reassessment after change, drift, incident, or organizational transfer
- **Practice 3:** Prove credential revocation, dependency removal, and data disposition



## Important distinctions

- **One-time launch approval:** This concept moves the engineering system toward expiring, continuously renewed authority.



## Implementation signals

- Require an owner heartbeat and authorization expiry
- Trigger reassessment after change, drift, incident, or organizational transfer
- Prove credential revocation, dependency removal, and data disposition

## Failure modes

- Dormant agents retaining valid credentials and integrations
- Ownership transfer assumed rather than explicitly authorized
