# Review tiers and credits

> Choose the right capability and cost envelope

| Tier     | Intended work                                                      | Execution posture                                  |
| -------- | ------------------------------------------------------------------ | -------------------------------------------------- |
| Standard | Fast pull-request review and deterministic checks                  | Light, capability-gated                            |
| Pro      | Deeper multi-pass review and broader interpreter/build evidence    | Light or isolated component execution              |
| Ultra    | Complex or security-sensitive changes and full repository analysis | Heavy isolated execution and full security surface |

Standard and Pro do not silently run unsupported work without isolation. They
emit a complete `cannot_run` receipt when required capability is unavailable.
Ultra is the appropriate tier when a full build, broad dependency restore, or
adversarial security analysis is required.

Credits are pooled per workspace. Usage records attribute requested/effective
tier, model/provider route, execution, and receipt cost to the repository and
actor. Reservations prevent concurrent jobs from overspending the workspace
pool; settlement releases unused reservations.
