## Why
`LOG_FORMAT=json` and `RUST_LOG` are supported by app-server, but the
behavior was only covered indirectly. We should verify the actual JSONL
written by both user-facing entry points: `codex app-server` and the
standalone `codex-app-server` binary.
The existing processor shutdown message also always said the channel
closed, even though the processor can exit for several different
reasons. Structured fields make that event more accurate and useful to
log consumers.
## What changed
- Record the processor `exit_reason`, remaining connection count, and
forced-shutdown state as structured tracing fields.
- Add a shared process-test helper that enables JSON logging, validates
every stderr line as JSON, and verifies the top-level timestamp is RFC
3339.
- Cover both `codex app-server` and `codex-app-server`, asserting the
stable `level`, `fields`, and `target` payload.
## Test plan
- `just test -p codex-app-server
standalone_app_server_emits_json_info_events`
- `just test -p codex-cli app_server_emits_json_info_events`
## Why
The transport in
[openai/codex#26242](https://github.com/openai/codex/pull/26242) needs
to be used by every remote orchestrator-to-executor connection before
JSON-RPC traffic starts.
## Changes
- Generates one executor Noise identity when remote exec-server starts
and registers its public key.
- Creates a harness identity for each physical remote environment
connection.
- Fetches a fresh registry bundle before connecting and validates the
authenticated harness key before completing the executor handshake.
- Multiplexes encrypted logical streams over the existing executor
WebSocket.
- Adds bounded stream, handshake-failure, and reassembly state.
- Adds safe lifecycle diagnostics without logging keys, authorizations,
plaintext, or ciphertext.
- Covers reconnects, replay rejection, validation failure, framing
limits, and encrypted JSON-RPC tool traffic.

## Why
`codex login` previously persisted newly issued OAuth credentials and
only then attempted to revoke the superseded refresh token. The old
credential must be revoked before a replacement browser or device-code
flow starts, and successful login must not perform any post-login
revocation attempt.
## What changed
- Revoke and clear existing stored auth before browser or device-code
CLI login begins.
- Remove superseded-token detection and revocation from the shared token
persistence path; successful login now only saves the new credentials.
- Read the raw configured auth store during CLI cleanup so
environment-provided auth cannot mask the stored refresh token.
- Preserve `auto` storage fallback semantics when keyring deletion fails
by clearing the fallback auth file.
- Add a process-level CLI regression test that requires the revoke
request to precede every device-login request and occur exactly once.
If replacement login is canceled or fails, the previous local
credentials have already been cleared. Remote revocation remains best
effort, matching explicit logout behavior.
## Validation
### Process-level before/after reproduction
I compiled the real `codex` CLI from the pre-fix parent (`14df0e8833`)
and from the PR implementation (`25c002f23b`; the login behavior is
unchanged at the current head), then ran the same device-code flow
against a local HTTP mock OAuth authority.
Each run:
1. Used a fresh temporary `CODEX_HOME` configured with
`cli_auth_credentials_store = "file"`.
2. Seeded that temporary home with managed ChatGPT auth containing
`old-access` and `old-refresh` tokens.
3. Pointed `CODEX_REVOKE_TOKEN_URL_OVERRIDE` at the mock `/oauth/revoke`
endpoint.
4. Ran the compiled CLI as:
```shell
CODEX_HOME=<temporary-home> \
CODEX_REVOKE_TOKEN_URL_OVERRIDE=<mock-issuer>/oauth/revoke \
<compiled-codex> login --device-auth --experimental_issuer <mock-issuer>
```
5. Recorded every request received by the mock authority. The mock
marked `new-access` valid when `/oauth/token` issued it and invalidated
it if `/oauth/revoke` arrived afterward, reproducing the observed
session-invalidating failure mode. After login exited, the harness also
verified the persisted refresh token and probed a protected endpoint
with `new-access`.
| Build | Observed request order | CLI/persistence result | `new-access`
probe |
| --- | --- | --- | --- |
| Pre-fix | `usercode → device token → OAuth token →
revoke(old-refresh)` | Exit `0`; `new-refresh` persisted | `401` |
| PR | `revoke(old-refresh) → usercode → device token → OAuth token` |
Exit `0`; `new-refresh` persisted | `200` |
The PR run therefore issued exactly one revocation request, before any
request that initiated the replacement login, and issued no revocation
after token exchange.
### Regression coverage
`codex-rs/cli/tests/login.rs::device_login_revokes_existing_auth_before_requesting_new_tokens`
runs the real first-party `codex` binary against a `wiremock` OAuth
server with an isolated temporary `CODEX_HOME`. It asserts:
- the exact request sequence is `/oauth/revoke`,
`/api/accounts/deviceauth/usercode`, `/api/accounts/deviceauth/token`,
then `/oauth/token`;
- there is exactly one revoke request and its body contains
`old-refresh` with the `refresh_token` hint;
- the completed login persists `new-refresh`.
Local validation:
- `just test -p codex-login` — 130 passed
- `just test -p codex-cli` — 280 passed, including the new process-level
regression test
- `just bazel-lock-check`
## Why
We want to remove implicit use of `$CODEX_HOME` from `codex-core` and
make embedders responsible for supplying user-level instructions. This
also ensures user instructions load when no primary environment is
selected.
## What changed
Stacked on #27415, which makes `codex exec` surface thread-scoped
runtime warnings.
- Added `UserInstructionsProvider` to `codex-extension-api`, with
absolute source attribution and recoverable loading warnings.
- Added `codex-home` with the filesystem-backed provider for
`AGENTS.override.md` and `AGENTS.md`, preserving precedence, fallback,
trimming, lossy UTF-8 handling, and the existing uncapped global
instruction size.
- Removed global instruction loading from `Config` and require
`ThreadManager` callers to inject a provider.
- Load provider instructions once for each fresh root runtime, including
runtimes without a primary environment. Running sessions retain their
snapshot, while child agents inherit the parent snapshot without
invoking the provider.
- Keep provider instructions separate while loading project `AGENTS.md`,
then assemble the model-visible instructions with the existing ordering,
source attribution, warning, and turn-context behavior.
- Wired the Codex home provider through the CLI, app server, MCP server,
core facade, and thread-manager sample.
## Validation
- `just test -p codex-home -p codex-extension-api`
- `just test -p codex-core agents_md`
- `just test -p codex-core guardian`
- `just test -p codex-app-server
thread_start_without_selected_environment_includes_only_global_instruction_source`
- `just test -p codex-exec warning`
- `just bazel-lock-check`
## Overview
Allow remote `codex exec-server` registration to use existing API-key
auth while restricting where those credentials can be sent.
- Accept `CodexAuth::ApiKey` for the normal `--remote` registration
path.
- Restrict API-key remote registration to HTTPS `openai.com` and
`openai.org` hosts and subdomains, with explicit HTTP loopback support
for local development.
- Disable registry registration redirects so credentials cannot be
forwarded to an unvalidated destination.
- Retain `--use-agent-identity-auth` as the explicit Agent Identity
path.
- Document remote registration using `CODEX_API_KEY`.
## Big picture
Callers can now provide an API key directly to `exec-server`
registration without first establishing ChatGPT login state:
```sh
CODEX_API_KEY="$OPENAI_API_KEY" \
codex exec-server \
--remote "https://<host>.openai.org/api" \
--environment-id "$ENVIRONMENT_ID"
```
## Validation
- `cargo fmt --all` (`just fmt` is not installed on this host)
- `cargo test -p codex-cli -p codex-exec-server`
## Why
Users have been reporting missing sessions in the app. The app server
thread listing is backed by the SQLite state DB, but the durable source
of truth for a thread still exists on disk as rollout JSONL. When the
state DB is incomplete, doctor should be able to show the mismatch
directly instead of leaving users with a generic state health result.
## What changed
This adds a `threads` doctor check that compares active and archived
rollout files under `CODEX_HOME` with rows in the SQLite `threads`
table. The check reports missing rollout rows, stale DB rows, archive
flag mismatches, duplicate rollout thread IDs, duplicate DB paths,
source/provider summaries, and bounded samples of affected rollout
paths.
It also adds a read-only state audit helper in `codex-rs/state` so
doctor can inspect thread rows without creating, migrating, or repairing
the database.

```
## Why
Issue #23031 was hard to diagnose from existing `codex doctor` output
because support could not see the OS language, resolved Git install, Git
repo metadata, Windows console mode/code page, or terminal-title inputs
that affect the TUI startup path. This adds those read-only signals to
`codex doctor` so Windows, Linux, and macOS reports carry the context
needed to investigate similar terminal rendering regressions.
Refs #23031
## What Changed
- Add a `system.environment` check for OS type/version, OS language, and
locale env vars.
- Add a `git.environment` check for the selected Git executable, PATH
Git candidates, version, exec path/build options, repository root,
branch, `.git` entry, and `core.fsmonitor`.
- Add Windows console code page and VT-processing mode details to
terminal diagnostics.
- Add a `terminal.title` check for configured/default title items and
resolved project-title source/value.
- Surface startup warning counts in config diagnostics and teach human
output to render the new categories.
## How to Test
1. On Windows, check out this branch and run `cargo run -p codex-cli --
doctor --summary`.
2. Confirm the Environment section includes `system`, `git`, `terminal`,
and `title` rows.
3. Run `cargo run -p codex-cli -- doctor --json`.
4. Confirm the JSON contains `system.environment`, `git.environment`,
and `terminal.title`; on Windows, confirm `terminal.env` details include
console code pages and `VT processing` for stdout/stderr.
5. From a non-git directory, run the same `doctor --json` command and
confirm the Git check reports `repo detected: false` rather than
warning.
Targeted tests:
- `cargo test -p codex-cli doctor`
- `cargo test -p codex-cli`
## Why
Plugin CLI installs should behave more like `apt-get install`:
configured marketplaces are the only install sources, the local
marketplace snapshot is the package index used at install time, and
`plugins/cache` is only a cache of already-downloaded plugin bytes.
That distinction matters once marketplaces and plugins have auth or
availability state. A repo-local marketplace manifest or leftover cached
plugin artifact should not silently become an install source unless the
marketplace was explicitly configured and its readable snapshot still
authorizes the plugin.
## What Changed
- add CLI commands to list configured marketplaces and add, list, or
remove marketplace plugins
- accept stable `plugin@marketplace` ids for add/remove while preserving
the explicit `--marketplace` form
- restrict `codex plugin add` and `codex plugin list` to configured
marketplaces instead of also discovering current-working-directory
marketplace roots
- fail `codex plugin add` and `codex plugin list` when a configured
marketplace snapshot is missing or malformed instead of treating it as
an empty source or a generic plugin miss
- preserve marketplace snapshot semantics: a configured local/Git
marketplace snapshot can authorize installs without consulting the
original upstream source
- allow `plugins/cache` reuse only after configured marketplace
resolution succeeds
- keep removal resilient after marketplace deletion or drift and ignore
malformed marketplace config entries in listing
## Commands Added

- `codex plugin add <plugin> --marketplace <marketplace>`

## Public Semantics
- `codex plugin add <plugin>@<marketplace>` succeeds only when
`<marketplace>` is configured and its local marketplace snapshot
contains `<plugin>`
- repo-local marketplaces are not install sources until the user runs
`codex plugin marketplace add ...`
- configured marketplace snapshots must be readable; missing or
malformed snapshots fail the CLI operation rather than silently falling
through to cache or empty results
- cached plugin artifacts can satisfy reinstall only when the configured
marketplace snapshot still authorizes that plugin
- cached plugin artifacts alone never make a plugin installable
## Tests
- `cargo test -p codex-cli --test plugin_cli`
- `cargo clippy -p codex-cli --tests -- -D warnings`
- `cargo test -p codex-cli`
- `git diff --check`
- `just bazel-lock-update`
- `just bazel-lock-check`
## Why
Users and support need a single command that captures the local Codex
runtime, configuration, auth, terminal, network, and state shape without
asking the user to know which diagnostic depth to choose first. `codex
doctor` now runs the useful checks by default and makes the detailed
human output the default because the command is usually run when someone
already needs context.
The command also targets concrete support failure modes we have seen
while iterating on the design:
- update-target mismatches like #21956, where the installed package
manager target can differ from the running executable
- terminal and multiplexer issues that depend on `TERM`, tmux/zellij
state, color handling, and TTY metadata
- provider-specific HTTP/WebSocket connectivity, including ChatGPT
WebSocket handshakes and API-key/provider endpoint reachability
- local state/log SQLite integrity problems and large rollout
directories
- feedback reports that need an attached, redacted diagnostic snapshot
without asking the user to run a second command
## What Changed
- Adds `codex doctor` as a grouped CLI diagnostic report with default
detailed output and `--summary` for the compact view.
- Adds stable report sections for Environment, Configuration, Updates,
Connectivity, and Background Server, plus a top Notes block that
promotes anomalies such as available updates, large rollout directories,
optional MCP issues, and mixed auth signals.
- Adds runtime provenance, install consistency, bundled/system search
readiness, terminal/multiplexer metadata, `config.toml` parse status,
auth mode details, sandbox details, feature flag summaries, update
cache/latest-version state, app-server daemon state, SQLite integrity
checks, rollout statistics, and provider-aware network diagnostics.
- Adds ChatGPT WebSocket diagnostics that report the negotiated HTTP
upgrade as `HTTP 101 Switching Protocols` and include timeout, DNS,
auth, and provider context in detailed output.
- Makes reachability provider-aware: API-key OpenAI setups check the API
endpoint, ChatGPT auth checks the ChatGPT path, and custom/AWS/local
providers check configured HTTP endpoints when available.
- Adds structured, redacted JSON output where `checks` is keyed by check
id and `details` is a key/value object for support tooling.
- Integrates doctor with feedback uploads by attaching a best-effort
`codex-doctor-report.json` report and adding derived Sentry tags for
overall status and failing/warning checks.
- Updates the TUI feedback consent copy so users can see that the doctor
report is included when logs/diagnostics are uploaded.
- Updates the CLI bug issue template to ask reporters for `codex doctor
--json` and render pasted reports as JSON.
## Example Output
The examples below are sanitized from local smoke runs with `--no-color`
so the structure is reviewable in plain text.

## How to Test
1. Run `cargo run --bin codex -- doctor --no-color`.
2. Confirm the detailed report is the default and includes promoted
Notes, grouped sections, terminal details, state DB integrity, rollout
stats, provider reachability, WebSocket diagnostics, and app-server
status.
3. Run `cargo run --bin codex -- doctor --summary --no-color`.
4. Confirm the compact view keeps the same sections and summary counts
but omits detailed key/value rows.
5. Run `cargo run --bin codex -- doctor --json`.
6. Confirm the output is redacted JSON, `checks` is an object keyed by
check id, and each check's `details` is a key/value object.
7. Preview the CLI bug issue template and confirm the `Codex doctor
report` field appears after the terminal field, asks for `codex doctor
--json`, and renders pasted output as JSON.
8. Start a feedback flow that includes logs.
9. Confirm the upload consent copy lists `codex-doctor-report.json`

## Why
Desktop and mobile Codex clients need a machine-readable way to
bootstrap and manage `codex app-server` on remote machines reached over
SSH. The same flow is also useful for bringing up app-server with
`remote_control` enabled on a fresh developer machine and keeping that
managed install current without requiring a human session.
## What changed
- add the new experimental `codex-app-server-daemon` crate and wire it
into `codex app-server daemon` lifecycle commands: `start`, `restart`,
`stop`, `version`, and `bootstrap`
- add explicit `enable-remote-control` and `disable-remote-control`
commands that persist the launch setting and restart a running managed
daemon so the change takes effect immediately
- emit JSON success responses for daemon commands so remote callers can
consume them directly
- support a Unix-only pidfile-backed detached backend for lifecycle
management
- assume the standalone `install.sh` layout for daemon-managed binaries
and always launch `CODEX_HOME/packages/standalone/current/codex`
- add bootstrap support for the standalone managed install plus a
detached hourly updater loop
- harden lifecycle management around concurrent operations, pidfile
ownership, stale state cleanup, updater ownership, managed-binary
preflight, Unix-only rejection, forced shutdown after the graceful
window, and updater process-group tracking/cleanup
- document the experimental Unix-only support boundary plus the
standalone bootstrap/update flow in
`codex-rs/app-server-daemon/README.md`
## Verification
- `cargo test -p codex-app-server-daemon -p codex-cli`
- live pid validation on `cb4`: `bootstrap --remote-control`, `restart`,
`version`, `stop`
## Follow-up
- Add updater self-refresh so the long-lived `pid-update-loop` can
replace its own executable image after installing a newer managed Codex
binary.
## Summary
`cargo test` has entails both running standard Rust tests and doctests.
It turns out that the doctest discovery is fairly slow, and it's a cost
you pay even for crates that don't include any doctests.
This PR disables doctests with `doctest = false` for crates that lack
any doctests.
For the collection of crates below, this speeds up test execution by
>4x.

## DISCLAIMER
This is experimental and no production service must rely on this
## Why
Built-in MCPs are product-owned runtime capabilities, but they were
previously flattened into the same config-backed stdio path as
user-configured servers. That made them depend on a hidden `codex
builtin-mcp` re-exec path, exposed them through config-oriented CLI
flows, and erased distinctions the runtime needs to preserve—most
notably whether an MCP call should count as external context for
memory-mode pollution.
## What changed
- Model product-owned built-ins separately from config-backed MCP
servers via `BuiltinMcpServer` and `EffectiveMcpServer`.
- Launch built-ins in process through a reusable async transport instead
of the hidden `builtin-mcp` stdio subcommand.
- Keep config-oriented CLI operations such as `codex mcp
list/get/login/logout` scoped to configured servers, while merging
built-ins only into the effective runtime server set.
- Retain server metadata after launch so parallel-tool support and
context classification come from the live server set; built-in
`memories` is now classified as local Codex state rather than external
context.
## Test plan
- `cargo test -p codex-mcp`
- `cargo test -p codex-core --test suite
builtin_memories_mcp_call_does_not_mark_thread_memory_mode_polluted_when_configured`

Keep extracting memories out of core and moving the write trigger in the

This removes the hidden `codex responses` CLI subcommand after
confirming no downstream callers rely on it, deleting the raw Responses
passthrough implementation, unregistering the subcommand, and dropping
the now-unused CLI dependencies on `codex-api` and
`codex-model-provider`.
## Summary
Adds the debug CLI entry point for reducing recorded rollout traces.
This gives developers a direct way to inspect whether the emitted trace
stream reduces into the expected conversation/runtime model.
## Stack
This is PR 5/5 in the rollout trace stack.
- [#18876](https://github.com/openai/codex/pull/18876): Add rollout
trace crate
- [#18877](https://github.com/openai/codex/pull/18877): Record core
session rollout traces
- [#18878](https://github.com/openai/codex/pull/18878): Trace tool and
code-mode boundaries
- [#18879](https://github.com/openai/codex/pull/18879): Trace sessions
and multi-agent edges
- [#18880](https://github.com/openai/codex/pull/18880): Add debug trace
reduction command
## Review Notes
This PR is intentionally last: it depends on the trace crate, core
recorder, runtime/tool events, and session/agent edge data all existing.
The command should remain a debug/developer tool and avoid adding new
runtime behavior.
The useful review question is whether the CLI exposes the reducer in the
smallest practical way for local inspection without turning the debug
command into a supported user-facing workflow.
## Summary
- Add `codex-model-provider` as the runtime home for model-provider
behavior that does not belong in `codex-core`, `codex-login`, or
`codex-api`.
- The new crate wraps configured `ModelProviderInfo` in a
`ModelProvider` trait object that can resolve the API provider config,
provider-scoped auth manager, and request auth provider for each call.
- This centralizes provider auth behavior in one place today, and gives
us an extension point for future provider-specific auth, model listing,
request setup, and related runtime behavior.
## Tests
Ran tests manually to make sure that provider auth under different
configs still work as expected.

## Changes
Allows sandboxes to restrict overall network access while granting
access to specific unix sockets on mac.
## Details
- `codex sandbox macos`: adds a repeatable `--allow-unix-socket` option.
- `codex-sandboxing`: threads explicit Unix socket roots into the macOS
Seatbelt profile generation.
- Preserves restricted network behavior when only Unix socket IPC is
requested, and preserves full network behavior when full network is
already enabled.
## Verification
- `cargo test -p codex-cli -p codex-sandboxing`
- `cargo build -p codex-cli --bin codex`
- verified that `codex sandbox macos --allow-unix-socket /tmp/test.sock
-- test-client` grants access as expected
## Summary
- add a top-level `codex exec-server` subcommand, marked experimental in
CLI help
- launch an adjacent or PATH-provided `codex-exec-server`, with a
source-tree `cargo run -p codex-exec-server --` fallback
- cover the new subcommand parser path
## Validation
- `just fmt`
- `git diff --check`
- not run: Rust test suite

## 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`](https://github.com/openai/codex/blob/f61e85dbfb5373cde6827d232ac8ea447c237e81/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`](https://github.com/openai/codex/blob/f61e85dbfb5373cde6827d232ac8ea447c237e81/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`.
This is the part 1 of 2 PRs that will delete the `tui` /
`tui_app_server` split. This part simply deletes the existing `tui`
directory and marks the `tui_app_server` feature flag as removed. I left
the `tui_app_server` feature flag in place for now so its presence
doesn't result in an error. It is simply ignored.
Part 2 will rename the `tui_app_server` directory `tui`. I did this as
two parts to reduce visible code churn.
## Summary
- add a new `codex-sandboxing` crate for sandboxing extraction work
- move the pure Linux sandbox argv builders and their unit tests out of
`codex-core`
- keep `core::landlock` as the spawn wrapper and update direct callers
to use `codex_sandboxing::landlock`
## Testing
- `cargo test -p codex-sandboxing`
- `cargo test -p codex-core landlock`
- `cargo test -p codex-cli debug_sandbox`
- `just argument-comment-lint`
## Notes
- this is step 1 of the move plan aimed at minimizing per-PR diffs
- no re-exports or no-op proxy methods were added
- Split the feature system into a new `codex-features` crate.
- Cut `codex-core` and workspace consumers over to the new config and
warning APIs.

This PR replicates the `tui` code directory and creates a temporary
parallel `tui_app_server` directory. It also implements a new feature
flag `tui_app_server` to select between the two tui implementations.
Once the new app-server-based TUI is stabilized, we'll delete the old
`tui` directory and feature flag.
## Problem
Browser login failures historically leave support with an incomplete
picture. HARs can show that the browser completed OAuth and reached the
localhost callback, but they do not explain why the native client failed
on the final `/oauth/token` exchange. Direct `codex login` also relied
mostly on terminal stderr and the browser error page, so even when the
login crate emitted better sign-in diagnostics through TUI or app-server
flows, the one-shot CLI path still did not leave behind an easy artifact
to collect.
## Mental model
This implementation treats the browser page, the returned `io::Error`,
and the normal structured log as separate surfaces with different safety
requirements. The browser page and returned error preserve the detail
that operators need to diagnose failures. The structured log stays
narrower: it records reviewed lifecycle events, parsed safe fields, and
redacted transport errors without becoming a sink for secrets or
arbitrary backend bodies.
Direct `codex login` now adds a fourth support surface: a small
file-backed log at `codex-login.log` under the configured `log_dir`.
That artifact carries the same login-target events as the other
entrypoints without changing the existing stderr/browser UX.
## Non-goals
This does not add auth logging to normal runtime requests, and it does
not try to infer precise transport root causes from brittle string
matching. The scope remains the browser-login callback flow in the
`login` crate plus a direct-CLI wrapper that persists those events to
disk.
This also does not try to reuse the TUI logging stack wholesale. The TUI
path initializes feedback, OpenTelemetry, and other session-oriented
layers that are useful for an interactive app but unnecessary for a
one-shot login command.
## Tradeoffs
The implementation favors fidelity for caller-visible errors and
restraint for persistent logs. Parsed JSON token-endpoint errors are
logged safely by field. Non-JSON token-endpoint bodies remain available
to the returned error so CLI and browser surfaces still show backend
detail. Transport errors keep their real `reqwest` message, but attached
URLs are surgically redacted. Custom issuer URLs are sanitized before
logging.
On the CLI side, the code intentionally duplicates a narrow slice of the
TUI file-logging setup instead of sharing the full initializer. That
keeps `codex login` easy to reason about and avoids coupling it to
interactive-session layers that the command does not need.
## Architecture
The core auth behavior lives in `codex-rs/login/src/server.rs`. The
callback path now logs callback receipt, callback validation,
token-exchange start, token-exchange success, token-endpoint non-2xx
responses, and transport failures. App-server consumers still use this
same login-server path via `run_login_server(...)`, so the same
instrumentation benefits TUI, Electron, and VS Code extension flows.
The direct CLI path in `codex-rs/cli/src/login.rs` now installs a small
file-backed tracing layer for login commands only. That writes
`codex-login.log` under `log_dir` with login-specific targets such as
`codex_cli::login` and `codex_login::server`.
## Observability
The main signals come from the `login` crate target and are
intentionally scoped to sign-in. Structured logs include redacted issuer
URLs, redacted transport errors, HTTP status, and parsed token-endpoint
fields when available. The callback-layer log intentionally avoids
`%err` on token-endpoint failures so arbitrary backend bodies do not get
copied into the normal log file.
Direct `codex login` now leaves a durable artifact for both failure and
success cases. Example output from the new file-backed CLI path:
Failing callback:

## Why
Compiling `codex-rs/core` is a bottleneck for local iteration, so this
change continues the ongoing extraction of config-related functionality
out of `codex-core` and into `codex-config`.
The goal is not just to move code, but to reduce `codex-core` ownership
and indirection so more code depends on `codex-config` directly.
## What Changed
- Moved config diagnostics logic from
`core/src/config_loader/diagnostics.rs` into
`config/src/diagnostics.rs`.
- Updated `codex-core` to use `codex-config` diagnostics types/functions
directly where possible.
- Removed the `core/src/config_loader/diagnostics.rs` shim module
entirely; the remaining `ConfigToml`-specific calls are in
`core/src/config_loader/mod.rs`.
- Moved `CONFIG_TOML_FILE` into `codex-config` and updated existing
references to use `codex_config::CONFIG_TOML_FILE` directly.
- Added a direct `codex-config` dependency to `codex-cli` for its
`CONFIG_TOML_FILE` use.
We are removing feature-gated shared crates from the `codex-rs`
workspace. `codex-common` grouped several unrelated utilities behind
`[features]`, which made dependency boundaries harder to reason about
and worked against the ongoing effort to eliminate feature flags from
workspace crates.
Splitting these utilities into dedicated crates under `utils/` aligns
this area with existing workspace structure and keeps each dependency
explicit at the crate boundary.
## What changed
- Removed `codex-rs/common` (`codex-common`) from workspace members and
workspace dependencies.
- Added six new utility crates under `codex-rs/utils/`:
- `codex-utils-cli`
- `codex-utils-elapsed`
- `codex-utils-sandbox-summary`
- `codex-utils-approval-presets`
- `codex-utils-oss`
- `codex-utils-fuzzy-match`
- Migrated the corresponding modules out of `codex-common` into these
crates (with tests), and added matching `BUILD.bazel` targets.
- Updated direct consumers to use the new crates instead of
`codex-common`:
- `codex-rs/cli`
- `codex-rs/tui`
- `codex-rs/exec`
- `codex-rs/app-server`
- `codex-rs/mcp-server`
- `codex-rs/chatgpt`
- `codex-rs/cloud-tasks`
- Updated workspace lockfile entries to reflect the new dependency graph
and removal of `codex-common`.
## Summary
- Retire the experimental TUI2 implementation and its feature flag.
- Remove TUI2-only config/schema/docs so the CLI stays on the
terminal-native path.
- Keep docs aligned with the legacy TUI while we focus on redraw-based
improvements.
## Customer impact
- Retires the TUI2 experiment and keeps Codex on the proven
terminal-native UI while we invest in redraw-based improvements to the
existing experience.
## Migration / compatibility
- If you previously set tui2-related options in config.toml, they are
now ignored and Codex continues using the existing terminal-native TUI
(no action required).
## Context
- What worked: a transcript-owned viewport delivered excellent resize
rewrap and high-fidelity copy (especially for code).
- Why stop: making that experience feel fully native across the
environment matrix (terminal emulator, OS, input modality, multiplexer,
font/theme, alt-screen behavior) creates a combinatorial explosion of
edge cases.
- What next: we are focusing on redraw-based improvements to the
existing terminal-native TUI so scrolling, selection, and copy remain
native while resize/redraw correctness improves.
## Testing

- just fmt
- cargo clippy --fix --all-features --tests --allow-dirty --allow-no-vcs

As explained in https://github.com/openai/codex/issues/8945 and
https://github.com/openai/codex/issues/8472, there are legitimate cases
where users expect processes spawned by Codex to inherit environment
variables such as `LD_LIBRARY_PATH` and `DYLD_LIBRARY_PATH`, where
failing to do so can cause significant performance issues.
This PR removes the use of
`codex_process_hardening::pre_main_hardening()` in Codex CLI (which was
added not in response to a known security issue, but because it seemed
like a prudent thing to do from a security perspective:
https://github.com/openai/codex/pull/4521), but we will continue to use
it in `codex-responses-api-proxy`. At some point, we probably want to
introduce a slightly different version of
`codex_process_hardening::pre_main_hardening()` in Codex CLI that
excludes said environment variables from the Codex process itself, but
continues to propagate them to subprocesses.
This PR introduces a `codex-utils-cargo-bin` utility crate that
wraps/replaces our use of `assert_cmd::Command` and
`escargot::CargoBuild`.
As you can infer from the introduction of `buck_project_root()` in this
PR, I am attempting to make it possible to build Codex under
[Buck2](https://buck2.build) as well as `cargo`. With Buck2, I hope to
achieve faster incremental local builds (largely due to Buck2's
[dice](https://buck2.build/docs/insights_and_knowledge/modern_dice/)
build strategy, as well as benefits from its local build daemon) as well
as faster CI builds if we invest in remote execution and caching.
See
https://buck2.build/docs/getting_started/what_is_buck2/#why-use-buck2-key-advantages
for more details about the performance advantages of Buck2.
Buck2 enforces stronger requirements in terms of build and test
isolation. It discourages assumptions about absolute paths (which is key
to enabling remote execution). Because the `CARGO_BIN_EXE_*` environment
variables that Cargo provides are absolute paths (which
`assert_cmd::Command` reads), this is a problem for Buck2, which is why
we need this `codex-utils-cargo-bin` utility.
My WIP-Buck2 setup sets the `CARGO_BIN_EXE_*` environment variables
passed to a `rust_test()` build rule as relative paths.
`codex-utils-cargo-bin` will resolve these values to absolute paths,
when necessary.

`load_config_layers_state()` should load config from a
`.codex/config.toml` in any folder between the `cwd` for a thread and
the project root. Though in order to do that,
`load_config_layers_state()` needs to know what the `cwd` is, so this PR
does the work to thread the `cwd` through for existing callsites.
A notable exception is the `/config` endpoint in app server for which a
`cwd` is not guaranteed to be associated with the query, so the `cwd`
param is `Option<AbsolutePathBuf>` to account for this case.
The logic to make use of the `cwd` will be done in a follow-up PR.
Introduce a new codex-tui2 crate that re-exports the existing
interactive TUI surface and delegates run_main directly to codex-tui.
This keeps behavior identical while giving tui2 its own crate for future
viewport work.
Wire the codex CLI to select the frontend via the tui2 feature flag.
When the merged CLI overrides include features.tui2=true (e.g. via
--enable tui2), interactive runs are routed through
codex_tui2::run_main; otherwise they continue to use the original
codex_tui::run_main.
Register Feature::Tui2 in the core feature registry and add the tui2
crate and dependency entries so the new frontend builds alongside the
existing TUI.
This is a stub that only wires up the feature flag for this.

$ codex debug seatbelt --log-denials bash -lc "(echo foo > ~/foo.txt)"
bash: /Users/nornagon/foo.txt: Operation not permitted
=== Sandbox denials ===
(bash) file-write-data /dev/tty
(bash) file-write-data /dev/ttys001
(bash) sysctl-read kern.ngroups
(bash) file-write-create /Users/nornagon/foo.txt
```
It operates by:
1. spawning `log stream` to watch system logs, and
2. tracking all descendant PIDs using kqueue + proc_listchildpids.
this is a "best-effort" technique, as `log stream` may drop logs(?), and
kqueue + proc_listchildpids isn't atomic and can end up missing very
short-lived processes. But it works well enough in my testing to be
useful :)
Update `codex generate-ts` to use the TS export code from
`app-server-protocol/src/export.rs`.
I realized there were two duplicate implementations of Typescript export
code:
- `app-server-protocol/src/export.rs`
- the `codex-protocol-ts` crate
The `codex-protocol-ts` crate that `codex generate-ts` uses is out of
date now since it doesn't handle the V2 namespace from:
https://github.com/openai/codex/pull/6212.
- Added the new codex-windows-sandbox crate that builds both a library
entry point (run_windows_sandbox_capture) and a CLI executable to launch
commands inside a Windows restricted-token sandbox, including ACL
management, capability SID provisioning, network lockdown, and output
capture
(windows-sandbox-rs/src/lib.rs:167, windows-sandbox-rs/src/main.rs:54).
- Introduced the experimental WindowsSandbox feature flag and wiring so
Windows builds can opt into the sandbox:
SandboxType::WindowsRestrictedToken, the in-process execution path, and
platform sandbox selection now honor the flag (core/src/features.rs:47,
core/src/config.rs:1224, core/src/safety.rs:19,
core/src/sandboxing/mod.rs:69, core/src/exec.rs:79,
core/src/exec.rs:172).
- Updated workspace metadata to include the new crate and its
Windows-specific dependencies so the core crate can link against it
(codex-rs/
Cargo.toml:91, core/Cargo.toml:86).
- Added a PowerShell bootstrap script that installs the Windows
toolchain, required CLI utilities, and builds the workspace to ease
development
on the platform (scripts/setup-windows.ps1:1).
- Landed a Python smoke-test suite that exercises
read-only/workspace-write policies, ACL behavior, and network denial for
the Windows sandbox
binary (windows-sandbox-rs/sandbox_smoketests.py:1).
This PR adds oauth login support to streamable http servers when
`experimental_use_rmcp_client` is enabled.
This PR is large but represents the minimal amount of work required for
this to work. To keep this PR smaller, login can only be done with
`codex mcp login` and `codex mcp logout` but it doesn't appear in `/mcp`
or `codex mcp list` yet. Fingers crossed that this is the last large MCP
PR and that subsequent PRs can be smaller.
Under the hood, credentials are stored using platform credential
managers using the [keyring crate](https://crates.io/crates/keyring).
When the keyring isn't available, it falls back to storing credentials
in `CODEX_HOME/.credentials.json` which is consistent with how other
coding agents handle authentication.
I tested this on macOS, Windows, WSL (ubuntu), and Linux. I wasn't able
to test the dbus store on linux but did verify that the fallback works.
One quirk is that if you have credentials, during development, every
build will have its own ad-hoc binary so the keyring won't recognize the
reader as being the same as the write so it may ask for the user's
password. I may add an override to disable this or allow
users/enterprises to opt-out of the keyring storage if it causes issues.
