## Why
This finishes the config-type move out of `codex-core` by removing the
temporary compatibility shim in `codex_core::config::types`. Callers now
depend on `codex-config` directly, which keeps these config model types
owned by the config crate instead of re-expanding `codex-core` as a
transitive API surface.
## What Changed
- Removed the `codex-rs/core/src/config/types.rs` re-export shim and the
`core::config::ApprovalsReviewer` re-export.
- Updated `codex-core`, `codex-cli`, `codex-tui`, `codex-app-server`,
`codex-mcp-server`, and `codex-linux-sandbox` call sites to import
`codex_config::types` directly.
- Added explicit `codex-config` dependencies to downstream crates that
previously relied on the `codex-core` re-export.
- Regenerated `codex-rs/core/config.schema.json` after updating the
config docs path reference.
## Why
`codex-core` was re-exporting APIs owned by sibling `codex-*` crates,
which made downstream crates depend on `codex-core` as a proxy module
instead of the actual owner crate.
Removing those forwards makes crate boundaries explicit and lets leaf
crates drop unnecessary `codex-core` dependencies. In this PR, this
reduces the dependency on `codex-core` to `codex-login` in the following
files:
```
codex-rs/backend-client/Cargo.toml
codex-rs/mcp-server/tests/common/Cargo.toml
```
## What
- Remove `codex-rs/core/src/lib.rs` re-exports for symbols owned by
`codex-login`, `codex-mcp`, `codex-rollout`, `codex-analytics`,
`codex-protocol`, `codex-shell-command`, `codex-sandboxing`,
`codex-tools`, and `codex-utils-path`.
- Delete the `default_client` forwarding shim in `codex-rs/core`.
- Update in-crate and downstream callsites to import directly from the
owning `codex-*` crate.
- Add direct Cargo dependencies where callsites now target the owner
crate, and remove `codex-core` from `codex-rs/backend-client`.
## Why
`codex-mcp` already owns the shared MCP API surface, including `auth`,
`McpConfig`, `CODEX_APPS_MCP_SERVER_NAME`, and tool-name helpers in
[`codex-rs/codex-mcp/src/mcp/mod.rs`](f61e85dbfb/codex-rs/codex-mcp/src/mcp/mod.rs (L1-L35)).
Re-exporting that surface from `codex_core::mcp` gives downstream crates
two import paths for the same API and hides the real crate dependency.
This PR keeps `codex_core::mcp` focused on the local `McpManager`
wrapper in
[`codex-rs/core/src/mcp.rs`](f61e85dbfb/codex-rs/core/src/mcp.rs (L13-L40))
and makes consumers import shared MCP APIs from `codex_mcp` directly.
## What
- Remove the `codex_mcp::mcp` re-export surface from `core/src/mcp.rs`.
- Update `codex-core` internals plus `codex-app-server`, `codex-cli`,
and `codex-tui` test code to import MCP APIs from `codex_mcp::mcp`
directly.
- Add explicit `codex-mcp` dependencies where those crates now use that
API surface, and refresh `Cargo.lock`.
## Verification
- `just bazel-lock-check`
- `cargo test -p codex-core -p codex-cli -p codex-tui`
- `codex-cli` passed.
- `codex-core` still fails five unrelated config tests in
`core/src/config/config_tests.rs` (`approvals_reviewer_*` and
`smart_approvals_alias_*`).
- A broader `cargo test -p codex-core -p codex-app-server -p codex-cli
-p codex-tui` run previously hung in `codex-app-server` test
`in_process_start_uses_requested_session_source_for_thread_start`.
- Split MCP runtime/server code out of `codex-core` into the new
`codex-mcp` crate. New/moved public structs/types include `McpConfig`,
`McpConnectionManager`, `ToolInfo`, `ToolPluginProvenance`,
`CodexAppsToolsCacheKey`, and the `McpManager` API
(`codex_mcp::mcp::McpManager` plus the `codex_core::mcp::McpManager`
wrapper/shim). New/moved functions include `with_codex_apps_mcp`,
`configured_mcp_servers`, `effective_mcp_servers`,
`collect_mcp_snapshot`, `collect_mcp_snapshot_from_manager`,
`qualified_mcp_tool_name_prefix`, and the MCP auth/skill-dependency
helpers. Why: this creates a focused MCP crate boundary and shrinks
`codex-core` without forcing every consumer to migrate in the same PR.
- Move MCP server config schema and persistence into `codex-config`.
New/moved structs/enums include `AppToolApproval`,
`McpServerToolConfig`, `McpServerConfig`, `RawMcpServerConfig`,
`McpServerTransportConfig`, `McpServerDisabledReason`, and
`codex_config::ConfigEditsBuilder`. New/moved functions include
`load_global_mcp_servers` and
`ConfigEditsBuilder::replace_mcp_servers`/`apply`. Why: MCP TOML
parsing/editing is config ownership, and this keeps config
validation/round-tripping (including per-tool approval overrides and
inline bearer-token rejection) in the config crate instead of
`codex-core`.
- Rewire `codex-core`, app-server, and plugin call sites onto the new
crates. Updated `Config::to_mcp_config(&self, plugins_manager)`,
`codex-rs/core/src/mcp.rs`, `codex-rs/core/src/connectors.rs`,
`codex-rs/core/src/codex.rs`,
`CodexMessageProcessor::list_mcp_server_status_task`, and
`utils/plugins/src/mcp_connector.rs` to build/pass the new MCP
config/runtime types. Why: plugin-provided MCP servers still merge with
user-configured servers, and runtime auth (`CodexAuth`) is threaded into
`with_codex_apps_mcp` / `collect_mcp_snapshot` explicitly so `McpConfig`
stays config-only.
## Description
Previously the `action` field on `EventMsg::GuardianAssessment`, which
describes what Guardian is reviewing, was typed as an arbitrary JSON
blob. This PR cleans it up and defines a sum type representing all the
various actions that Guardian can review.
This is a breaking change (on purpose), which is fine because:
- the Codex app / VSCE does not actually use `action` at the moment
- the TUI code that consumes `action` is updated in this PR as well
- rollout files that serialized old `EventMsg::GuardianAssessment` will
just silently drop these guardian events
- the contract is defined as unstable, so other clients have a fair
warning :)
This will make things much easier for followup Guardian work.
## Why
The old guardian review payloads worked, but they pushed too much shape
knowledge into downstream consumers. The TUI had custom JSON parsing
logic for commands, patches, network requests, and MCP calls, and the
app-server protocol was effectively just passing through an opaque blob.
Typing this at the protocol boundary makes the contract clearer.
Makes fuzzy file search use case-insensitive matching instead of
smart-case in `codex-file-search`. I find smart-case to be a poor user
experience -using the wrong case for a letter drops its match so
significantly, it often drops off the results list, effectively making a
search case-sensitive.
## Why
Bazel clippy now catches lints that `cargo clippy` can still miss when a
crate under `codex-rs` forgets to opt into workspace lints. The concrete
example here was `codex-rs/app-server/tests/common/Cargo.toml`: Bazel
flagged a clippy violation in `models_cache.rs`, but Cargo did not
because that crate inherited workspace package metadata without
declaring `[lints] workspace = true`.
We already mirror the workspace clippy deny list into Bazel after
[#15955](https://github.com/openai/codex/pull/15955), so we also need a
repo-side check that keeps every `codex-rs` manifest opted into the same
workspace settings.
## What changed
- add `.github/scripts/verify_cargo_workspace_manifests.py`, which
parses every `codex-rs/**/Cargo.toml` with `tomllib` and verifies:
- `version.workspace = true`
- `edition.workspace = true`
- `license.workspace = true`
- `[lints] workspace = true`
- top-level crate names follow the `codex-*` / `codex-utils-*`
conventions, with explicit exceptions for `windows-sandbox-rs` and
`utils/path-utils`
- run that script in `.github/workflows/ci.yml`
- update the current outlier manifests so the check is enforceable
immediately
- fix the newly exposed clippy violations in the affected crates
(`app-server/tests/common`, `file-search`, `feedback`,
`shell-escalation`, and `debug-client`)

## Summary
- Replace the separate external auth enum and refresher trait with a
single `ExternalAuth` trait in login auth flow
- Move bearer token auth behind `BearerTokenRefresher` and update
`AuthManager` and app-server wiring to use the generic external auth API
## Summary
`AuthManager` and `UnauthorizedRecovery` already own token resolution
and staged `401` recovery. The missing piece for provider auth was a
bearer-only mode that still fit that design, instead of pushing a second
auth abstraction into `codex-core`.
This PR keeps the design centered on `AuthManager`: it teaches
`codex-login` how to own external bearer auth directly so later provider
work can keep calling `AuthManager.auth()` and `UnauthorizedRecovery`.
## Motivation
This is the middle layer for #15189.
The intended design is still:
- `AuthManager` encapsulates token storage and refresh
- `UnauthorizedRecovery` powers staged `401` recovery
- all request tokens go through `AuthManager.auth()`
This PR makes that possible for provider-backed bearer tokens by adding
a bearer-only auth mode inside `AuthManager` instead of building
parallel request-auth plumbing in `core`.
## What Changed
- move `ModelProviderAuthInfo` into `codex-protocol` so `core` and
`login` share one config shape
- add `login/src/auth/external_bearer.rs`, which runs the configured
command, caches the bearer token in memory, and refreshes it after `401`
- add `AuthManager::external_bearer_only(...)` for provider-scoped
request paths that should use command-backed bearer auth without
mutating the shared OpenAI auth manager
- add `AuthManager::shared_with_external_chatgpt_auth_refresher(...)`
and rename the other `AuthManager` helpers that only apply to external
ChatGPT auth so the ChatGPT-only path is explicit at the call site
- keep external ChatGPT refresh behavior unchanged while ensuring
bearer-only external auth never persists to `auth.json`
## Testing
- `cargo test -p codex-login`
- `cargo test -p codex-protocol`

* __->__ #16287
## Summary
`ExternalAuthRefresher` was still shaped around external ChatGPT auth:
`ExternalAuthTokens` always implied ChatGPT account metadata even when a
caller only needed a bearer token.
This PR generalizes that contract so bearer-only sources are
first-class, while keeping the existing ChatGPT paths strict anywhere we
persist or rebuild ChatGPT auth state.
## Motivation
This is the first step toward #15189.
The follow-on provider-auth work needs one shared external-auth contract
that can do both of these things:
- resolve the current bearer token before a request is sent
- return a refreshed bearer token after a `401`
That should not require a second token result type just because there is
no ChatGPT account metadata attached.
## What Changed
- change `ExternalAuthTokens` to carry `access_token` plus optional
`ExternalAuthChatgptMetadata`
- add helper constructors for bearer-only tokens and ChatGPT-backed
tokens
- add `ExternalAuthRefresher::resolve()` with a default no-op
implementation so refreshers can optionally provide the current token
before a request is sent
- keep ChatGPT-only persistence strict by continuing to require ChatGPT
metadata anywhere the login layer seeds or reloads ChatGPT auth state
- update the app-server bridge to construct the new token shape for
external ChatGPT auth refreshes
## Testing
- `cargo test -p codex-login`
