CARBON
Engineering confidence
Private feedback workspace
Human perspective · local first

# Feedback that returns to the work.

Respond to a precise artifact and focus area. Your qualitative observations are saved into the project’s CARBON state so the coding agent can use—not merely summarize—them.

Privacy boundary
Local unless you choose private delivery.

The local workspace never sends your feedback to a public CARBON service. An external reviewer requires a separately configured private Feedback Service.

### Private-service delivery is explicit.

When an owner configures the self-hosted Feedback Service and a recipient email, it sends a rich invitation with a capability link to a protected web response page.

- No public CARBON cloud fallback
- Service key never persists in the project
- Do not put secrets in feedback or artifact URLs

### What CARBON does next

Feedback can change persona charters, value checks, release interpretation, and what a human should decide. It does not turn an untested behavior into a pass.
