-## Extension Capabilities
-
-Extensions advertise namespaced string capabilities through `PeerMetadata`.
-Use shared constants in `extension_protocol` and pass optional capabilities to
-`extension_metadata`; do not add per-driver booleans for policy features.
-Negotiation validates and retains the extension's supported capability list.
-
-`POLICY_UI_V1` (`openshell.policy.ui.v1`) declares complete startup UI-policy
-support. The gateway checks the effective policy before driver validation or
-creation and rejects any explicit UI section when the capability is absent.
-Supporting drivers validate and enforce the concrete settings. Omitted UI
-preserves existing driver behavior; changing UI requires sandbox recreation.

    - **Modifying an existing policy**: Edit the specific policy in place — add/remove endpoints, change access presets, update rules, add binaries, etc. A rule authorizes every binary it lists to reach every endpoint and port it lists, so adding one binary grants it all of that rule's endpoints, and adding one endpoint grants it to all of that rule's binaries. State the resulting pairs to the user before writing them. When the user wants a binary to reach only part of a rule's endpoints, put that binary and those endpoints in a separate rule instead of extending the existing one.
