## Why The migration away from `SandboxPolicy` needs new configs to start from permissions profiles instead of deriving profiles from legacy sandbox modes. Existing users can have empty `config.toml` files, and we should not rewrite user-owned config files that may live in shared repositories. This PR introduces built-in profile names so an empty config can resolve to a canonical `PermissionProfile`, while explicit named `[permissions]` profiles still behave predictably. ## What changed - Adds built-in `default_permissions` profile names: - `:read-only` maps to `PermissionProfile::read_only()`. - `:workspace` maps to the workspace-write profile, including project-root metadata carveouts. - `:danger-no-sandbox` maps to `PermissionProfile::Disabled`, preserving the distinction between no sandbox and a broad managed sandbox. - Reserves the `:` prefix for built-in profiles so user-defined `[permissions]` profiles cannot collide with future built-ins. - Allows `default_permissions` to reference a built-in profile without requiring a `[permissions]` table. - Makes an otherwise empty config choose a built-in profile by trust/platform context: trusted or untrusted project roots use `:workspace` when the platform supports that sandbox, while roots without a trust decision use `:read-only`. - Keeps legacy `sandbox_mode` configs on the legacy path, and still rejects user-defined `[permissions]` profiles that omit `default_permissions` so we do not silently guess among custom profiles. - Preserves compatibility behavior for implicit defaults: bare `network.enabled = true` allows runtime network without starting the managed proxy, explicit profile proxy policy still starts the proxy, and implicit workspace/add-dir roots keep legacy metadata carveouts. ## Verification - `cargo test -p codex-core builtin --lib` - `cargo test -p codex-core profile_network_proxy_config` - `cargo test -p codex-core implicit_builtin_workspace_profile_preserves_add_dir_metadata_carveouts` - `cargo test -p codex-core permissions_profiles_network_enabled_allows_runtime_network_without_proxy` - `cargo test -p codex-core permissions_profiles_proxy_policy_starts_managed_network_proxy` ## Documentation Public Codex config docs should mention these built-in names when the `[permissions]` config format is ready to document as stable. --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

## Summary - Move TUI permission state from legacy `SandboxPolicy` values to canonical `PermissionProfile` values across presets, app events, chat widget state, app commands, thread routing, and cached thread session state. - Keep app-server compatibility boundaries explicit: embedded sessions send `permissionProfile`, while remote sessions send only a legacy `sandbox` projection and fall back to read-only when a custom profile cannot be projected. - Update status/add-dir UI summaries and snapshots to render the active permission profile, including workspace profiles selected by the new built-in defaults. ## Verification - `rg '\bSandboxPolicy\b' codex-rs/tui -n` returns no matches. - `cargo test -p codex-tui` - `cargo check -p codex-tui --tests` - `cargo test -p codex-tui additional_dirs` - `just fmt` - `just fix -p codex-tui` --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

Summary
This continues the test-side migration away from
SandboxPolicyby removing the remaining legacy policy setup incore/tests/suite/tools.rs. The affected test was already modeling a profile-backed filesystem policy with a deny-read glob, so configuring the test throughPermissions::set_permission_profile()is a better match for the behavior being exercised.Changes
SandboxPolicyimport fromcore/tests/suite/tools.rs.PermissionProfileinstead of creating a legacy read-only policy first.Verification
