Concepts¶
Mental model for how Portal evaluates rules across admission, audit, and network layers.
- Architecture — layer model and component diagram.
- Admission vs audit — synchronous denial vs informer-driven review.
- Cross-resource lookups — referencing related objects from a rule.
- Context and pod sugar — the evaluation context and pod-specific shortcuts.
- Actions and rate limiting — what happens after a match, and the rate-limit semantics.
- Fail-closed — what Portal does when the engine itself is unhealthy.
