## Glossary Terms

### CIBA  
Client-Initiated Backchannel Authentication: an out-of-band flow that pauses a sensitive agent action for explicit, attributable human approval.

### Code agent  
Autonomous software that reads code, runs commands, calls tools, and changes systems on a developer's behalf. Securing one means controlling what it can access while it runs, and proving afterward what it did.

### Confused deputy  
An attack where a low-privilege agent tricks a higher-privilege one into acting on its behalf. Scope attenuation prevents it: a sub-agent provably cannot exceed its parent's authority.

### Delegated authority  
The model where an agent acts on behalf of a human or another agent, holding strictly less authority than the principal that authorized it, and provably distinct from that principal.

### Delegation depth  
How many on-behalf-of hops a credential sits from its original human authorizer. Highflame enforces depth as a first-class policy primitive.
