## Summary Today `SandboxPermissions::requires_additional_permissions()` does not actually mean "is `WithAdditionalPermissions`". It returns `true` for any non-default sandbox override, including `RequireEscalated`. That broad behavior is relied on in multiple `main` callsites. The naming is security-sensitive because `SandboxPermissions` is used on shell-like tool calls to tell the executor how a single command should relate to the turn sandbox: - `UseDefault`: run with the turn sandbox unchanged - `RequireEscalated`: request execution outside the sandbox - `WithAdditionalPermissions`: stay sandboxed but widen permissions for that command only ## Problem The old helper name reads as if it only applies to the `WithAdditionalPermissions` variant. In practice it means "this command requested any explicit sandbox override." That ambiguity made it easy to read production checks incorrectly and made the guardian change look like a standalone `main` fix when it is not. On `main` today: - `shell` and `unified_exec` intentionally reject any explicit `sandbox_permissions` request unless approval policy is `OnRequest` - `exec_policy` intentionally treats any explicit sandbox override as prompt-worthy in restricted sandboxes - tests intentionally serialize both `RequireEscalated` and `WithAdditionalPermissions` as explicit sandbox override requests So changing those callsites from the broad helper to a narrow `WithAdditionalPermissions` check would be a behavior change, not a pure cleanup. ## What This PR Does - documents `SandboxPermissions` as a per-command sandbox override, not a generic permissions bag - adds `requests_sandbox_override()` for the broad meaning: anything except `UseDefault` - adds `uses_additional_permissions()` for the narrow meaning: only `WithAdditionalPermissions` - keeps `requires_additional_permissions()` as a compatibility alias to the broad meaning for now - updates the current broad callsites to use the accurately named broad helper - adds unit coverage that locks in the semantics of all three helpers ## What This PR Does Not Do This PR does not change runtime behavior. That is intentional. --------- Co-authored-by: Codex <noreply@openai.com> |

codex-protocol
This crate defines the "types" for the protocol used by Codex CLI, which includes both "internal types" for communication between codex-core and codex-tui, as well as "external types" used with codex app-server.
This crate should have minimal dependencies.
Ideally, we should avoid "material business logic" in this crate, as we can always introduce Ext-style traits to add functionality to types in other crates.
