## What changed
- Install the git attribution extension in the app server, MCP server, and `codex debug prompt-input` so authenticated workspace policy controls the commit and pull request attribution instructions sent to the model.
- Resolve attribution settings from the process-level ChatGPT base URL, independent of per-thread or per-tool configuration overrides.
- Treat git attribution as contextual developer content when mapping model events.
## Testing
- Cover policy fetch retries, workspace switches, rollbacks, cold thread resumes with legacy instructions, MCP tool calls, and prompt-debug output.
GitOrigin-RevId: 57d182c432c20d7c1c6c429057b6163c9f32088d
## What changed
- Add `SqliteConfig` to own the resolved SQLite home, runtime database paths,
and shared read/write and read-only pool settings.
- Pass the configuration through state and local thread-store consumers,
replacing standalone path helpers and duplicated connection setup.
GitOrigin-RevId: 7351b08da94b5c8b6c0bbe492f86aeeca0699d3c
## Why
ChatGPT token refresh requests need to follow the same configured routing policy as other authentication traffic, including environments that use the system proxy.
## What changed
- Require an `AuthRouteConfig` throughout login, logout, token refresh, personal access token, and agent identity flows.
- Build auth HTTP clients directly from that configuration instead of falling back to a default HTTP client when routing configuration is absent.
## Testing
- Add an integration test that refreshes a token through a cached system-proxy route and verifies the proxy receives the expected request.
GitOrigin-RevId: 7d54ab3219939a49921c51faf08cd4c2eabca51c
## Why
Auth routing represented the default proxy policy as an absent configuration,
leaving consumers to reconstruct the fallback HTTP client independently. Carry
the application's resolved policy explicitly so auth and related requests use
the same client configuration.
## What changed
- Build `AuthRouteConfig` from the resolved `HttpClientFactory` for both
`ReqwestDefault` and `RespectSystemProxy` policies.
- Pass that route configuration through login, auth, cloud task, and cloud
configuration flows, and reuse its factory when loading cloud configuration.
- Log cloud-task configuration load failures before falling back to the
transport-default proxy policy.
## Testing
Extended configuration tests to verify that effective and bootstrap auth routes
select the expected proxy policy when system-proxy support is enabled or
disabled by feature requirements.
GitOrigin-RevId: d03802e2660f5cf6d940e8e718ec5c82ede7eab1
## What changed
- Assign IDs to client-created response items in every session, including streamed items, forked history, compaction results, and non-OpenAI provider requests.
- Preserve server-provided IDs and stable generated IDs across persisted and resumed conversations while continuing to omit unprefixed server IDs from outbound requests.
- Retire `features.item_ids` as a configurable feature. Existing configuration and CLI toggles remain accepted as compatibility no-ops.
## Testing
- Cover default ID assignment, persistence and resume behavior, remote compaction, provider requests, WebSocket requests, and removed-feature compatibility.
GitOrigin-RevId: 7a09e2d07d2606c2ef1e8e2283d36cb555557eae
## Why
`codex-http-client` is the intended owner of direct `reqwest` usage.
## What changed
- Build Codex's default and route-aware clients with `HttpClientBuilder`, and return `HttpClient` directly to API, model discovery, auth, remote control, skills, and extension callers.
- Preserve custom CA, proxy, Cloudflare cookie, sandbox, and request-logging policies while removing `codex-login`'s direct `reqwest` dependency.
- Use shared HTTP types for auth headers, status codes, transport errors, and login-server tests.
## Testing
- Add a Linux integration test verifying that a regular Responses API turn traverses the configured system proxy.
GitOrigin-RevId: 714695fb80762d2083e2f7a6414183e2b3b63854
## Why
Elevated Windows sandboxes need stable managed-proxy ports while preserving the network policy and environment attribution of each sandboxed process.
## What changed
- Keep shared HTTP and SOCKS5 loopback ingress listeners alive across managed-proxy instances.
- Add a per-route restricting SID to elevated sandbox tokens and dispatch incoming connections to the matching proxy policy after attributing the client process.
- Reject connections without exactly one registered route, remove routes when their proxy handle is dropped, and keep unsandboxed Windows launches off the managed ingress.
- Provision the elevated sandbox with the configured proxy ports and local-binding setting, honoring the selected profile and CLI overrides.
## Testing
- Add Windows unit tests for TCP ownership attribution, route selection, restricting-token propagation, and setup settings.
- Add an end-to-end Windows test covering stable ports, isolated environment policies, HTTP and SOCKS5 routing, and route teardown.
GitOrigin-RevId: 783fac6e0f904dc9bb1955b75d4a5895e8bb9690
## What changed
Redirect stdin to null when launching:
- `codex doctor --json` for uploaded diagnostic reports
- Git commands used by `codex doctor`
- ripgrep searches over rollout files
- the Windows sandbox setup refresh helper
This keeps these non-interactive subprocesses from reading Codex's inherited
input stream.
GitOrigin-RevId: 063d191b0b1b849d74b55a7d6ff2f0b3d5212c86
## Why
With `allow_local_binding = false`, proxy-aware clients bypassed the managed
proxy for loopback and private IP targets. This prevented explicit local IP and
`localhost` allowlist entries from taking effect.
## What changed
- Route local targets through the managed proxy when local binding is disabled,
while preserving direct access when it is enabled.
- Allow a non-public connection only when its requested IP literal or
`localhost` target is explicitly permitted. Continue blocking private
addresses reached through unrelated hostnames.
- Bypass inherited upstream proxies for non-public targets so Codex applies the
local-target policy directly.
## Testing
Added connector, upstream proxy, environment override, and Linux sandbox
coverage for explicitly allowlisted loopback access.
GitOrigin-RevId: 35e0d73633d5051816e096bc5aa8d586aec5eea4
## Why
The PID-managed daemon updater downloaded the standalone installer directly,
bypassing Codex's configured outbound proxy policy.
## What changed
- Build the updater's HTTP client from the effective Codex configuration so
`features.respect_system_proxy` also applies to installer downloads.
- Use the route-aware client pool for the installer request.
- Warn and fall back to the default `reqwest` proxy behavior when configuration
cannot be loaded, allowing updates to continue.
## Testing
Added tests for proxy-policy selection, configuration-load fallback, exact
installer URL usage, byte preservation, and non-success HTTP responses.
GitOrigin-RevId: 559668eb40314d43afa6512da66e59e32cc1b93c
## What changed
- Remove the `spawn_agents_on_csv` and `report_agent_job_result` tools and their agent-job runtime and state models.
- Drop the legacy `agent_jobs` and `agent_job_items` tables during state database migration.
- Keep `features.enable_fanout` and `agents.job_max_runtime_seconds` accepted as no-op compatibility settings while omitting them from the generated configuration schema.
## Testing
- Verify upgrades remove both legacy agent-job tables.
- Verify the removed feature and configuration keys still parse without taking effect.
GitOrigin-RevId: 8cc3337da78c67162229f02f40a747f503542646
## Why
`SqliteConfig` stores its home as an `AbsolutePathBuf`, but its test constructor
previously accepted a `PathBuf` and checked the absolute-path invariant at
runtime.
## What changed
- Make `SqliteConfig::new_for_testing` accept an `AbsolutePathBuf` directly,
removing its fallible conversion and `expect`.
- Update SQLite test setup to convert temporary directory paths with
`PathExt::abs` at each call site.
GitOrigin-RevId: 93585b9aea805e2449b3465ac20eeb39417ed555
## Why
The thread inventory check compared state database rows only with plain
`.jsonl` rollout files. Once a rollout was compressed to `.jsonl.zst`, the
check could report its canonical database row as stale and omit the rollout
from parity results.
## What changed
- Scan completed compressed rollouts and match them to database rows using
their canonical `.jsonl` paths.
- Prefer a plain rollout when both plain and compressed siblings exist, and
ignore compression temporary files.
- Keep unreadable compressed rollouts in the set of existing paths so they
produce scan errors without also producing misleading stale-row reports.
- Use canonical paths when deriving legacy thread IDs and archived status.
## Testing
Added coverage for active and archived compressed rollouts, plain/compressed
siblings, metadata and legacy filename IDs, corrupt compressed data, and
compression temporary files.
GitOrigin-RevId: 2461376432194a4062beedbe875aa7002dd2049f
## What changed
- Add `SqliteConfig` as the shared entry point for read-write and read-only SQLite pools.
- Apply consistent WAL, synchronization, auto-vacuum, busy-timeout, logging, and pool-size settings to writable Codex databases.
- Route state runtime, audit, CLI, and test database connections through the shared configuration.
## Testing
- Run migration tests against temporary on-disk databases opened through `SqliteConfig`, including the concurrent-writer repair case.
GitOrigin-RevId: e3946b98bde04c47574532ac8b1a7bb2b03edd97
## Why
The Desktop app can use Codex or ChatGPT branding while retaining stable platform identities. CLI discovery and TUI handoff should not depend on a single display name or hardcoded executable path.
## What changed
- On macOS, search for both `ChatGPT.app` and `Codex.app`, and accept only bundles with the `com.openai.codex` identifier.
- On Windows, detect installs by their package app ID and resolve the `codex` protocol executable from the AppX manifest before handing off a TUI session.
- Use “Desktop app” consistently in CLI and TUI user-facing text.
## Testing
Add coverage for selecting a ChatGPT-named Codex bundle and rejecting the classic ChatGPT bundle.
GitOrigin-RevId: b84a56eb6e960712152e1a9b023ab530ec9a354a
## Why
Callers that only need session metadata should not scan an entire rollout or fail on an unreadable tail after valid metadata.
## What changed
- Read session metadata directly from the rollout line reader, stopping as soon as it is found for both plain and compressed rollouts while preserving pre-header and validation behavior.
- Bound the doctor thread inventory scan to the first 64 non-empty header lines. Prefer the metadata thread ID and retain the validated filename fallback for legacy rollouts without metadata.
## Testing
- Cover invalid UTF-8 tails, compressed rollouts, pre-header records, metadata and filename ID mismatches, the scan boundary, legacy fallback, and unusable headers.
GitOrigin-RevId: 49576bd2877942e64082ce5ed057ecc848c025ec
## Why
Paginated thread history needs durable ordering so consumers can process a rollout suffix without rebuilding all earlier history.
## What changed
- Add optional, zero-based ordinals to `RolloutLine` records in paginated rollouts while leaving legacy rollout serialization unchanged.
- Continue ordinals from the last valid record when appending or resuming, including after gaps or an incomplete tail, and reject overflow without appending.
- Add a stateless `project_rollout_line` helper that maps canonical turn lifecycle and completed-item records into thread-history change sets.
## Testing
- Cover ordinal assignment, legacy compatibility, resume and tail recovery, overflow handling, and thread-history projection for completed, failed, and interrupted turns.
GitOrigin-RevId: 3a9bb6cd2a1f674a9f154342e96e9aa3d8330781
## Why
Paginated thread history needs its own SQLite database to avoid adding lock
contention to the main state store.
## What changed
- Add the `thread_history_1.sqlite` path and migration scaffolding.
- Create tables and pagination indexes for projected turns and items, plus a
per-thread projection checkpoint.
- Register the database with runtime diagnostics, Bazel inputs, and database
telemetry.
GitOrigin-RevId: d194310835f1df2a2a29c7827d77ca37eabbd0a3
## Why
Bazel-backed end-to-end macrobenchmark plumbing needs a small,
deterministic first consumer that does not couple the shared
infrastructure to the remote-skill scenario.
## What
- add `codex_e2e_benchmark`, a small macro for Bazel-only Divan
benchmarks and runtime binary runfiles
- keep benchmark sources under `e2e_benches/` so Cargo does not
auto-discover them
- add a CLI example that resolves the real `codex` binary and measures
`codex --help`
- assert the spawned command succeeds
## Validation
- `bazel test --compilation_mode=fastbuild
--@rules_rust//rust/settings:extra_rustc_flag=-Cdebug-assertions=no

## Why
Responses WebSockets are the normal lower-latency transport for
WebSocket-capable providers. They must not bypass an OS-selected proxy
when `features.respect_system_proxy` is enabled, but disabling
WebSockets whenever the feature is enabled would impose a substantial
performance penalty.
Merged PR #31622 introduced the reusable proxy-aware WebSocket
transport. This PR makes the Responses API its first consumer so the
existing fast path uses the same effective proxy and trust policy as
HTTP.
## What changed
- Register `codex-websocket-client` as a workspace dependency and use it
from `codex-api`.
- Feed the shared crate’s route-independent `WebSocketConnection` into
the existing Responses message pump.
- Require a configured `HttpClientFactory` for normal Responses
WebSocket connections and the CLI doctor probe, so neither path can open
a connection without consulting the effective proxy policy.
- Pass the session factory from `core` and the effective configuration
factory from `doctor`.
- Add an end-to-end Responses test that enables `RespectSystemProxy`,
asserts the resolved policy, completes a turn over WebSocket, and
verifies the connection and request counts.
- Keep the existing Responses protocol handling, ping/pong pump, and
session-scoped HTTP fallback unchanged.
The DNS, proxy, TLS, custom-CA, and Happy Eyeballs implementation and
its transport tests live in merged PR #31622. This PR deliberately
contains only the Responses integration and does not duplicate that
transport code.
## Review guide
1. `codex-rs/codex-api/src/endpoint/responses_websocket.rs` constructs
the shared connector and adapts its uniform stream to the existing pump.
2. `codex-rs/core/src/client.rs` supplies the session-scoped factory for
production Responses connections.
3. `codex-rs/cli/src/doctor.rs` supplies the effective configuration
factory to the handshake probe.
4. `codex-rs/core/tests/suite/client_websockets.rs` covers the
enabled-feature path end to end.

## Why
The Codex JavaScript shim currently distinguishes npm and Bun installs,
but a global pnpm install falls back to npm. That causes the native CLI,
`codex doctor`, and update flows to report or run npm commands even
though pnpm owns the installation. pnpm also allows its global package
and bin directories to differ, so `PNPM_HOME` does not reliably identify
the package owner.
## What changed
- detect pnpm-managed installs by finding pnpm's
`node_modules/.modules.yaml` metadata from the launched JavaScript
entrypoint
- pass a mutually exclusive `CODEX_MANAGED_BY_PNPM` marker into the
native CLI
- represent pnpm in install context, doctor output, version checks, and
TUI update actions without changing the existing public
`InstallContext::from_exe` signature
- recommend `pnpm add -g @openai/codex` for pnpm-managed installs and
snapshot the rendered TUI update notice
Validated with the 9-test install-context suite, the focused pnpm TUI
snapshot test, and Node's syntax check for the launcher.
Closes https://github.com/openai/codex/issues/10294.
## Summary
- Adds `writes` to `AppToolApproval` and exposes it through config and
app-server schemas, including
`[apps._default].default_tools_approval_mode`.
- In `writes`, tools with `readOnlyHint = true` skip approval; all other
tools prompt, including non-destructive writes and tools without
annotations.
- Prevents session or persistent approval choices in this mode so later
writes still prompt.
## Why
`auto` only prompts for risk-hinted actions, while `prompt` also
interrupts reads. Apps need a middle mode that gates writes without
prompting for declared read-only actions.

## Summary
- project effective marketplace/plugin config through the enterprise
source policy so blocked installed plugins become inactive
- filter plugin list/read/discovery and CLI marketplace source/snapshot
reporting using the same policy
- enforce source admission for background marketplace cache refreshes
- continue refreshing/upgrading independent marketplaces and plugins
when one entry fails, returning per-entry errors
- include policy-projected plugin state in cache and refresh keys so
requirement changes invalidate stale results
## Stack
This is PR 2 of 2 and is based on #29690. Review the admission model and
source matcher in #29690 first; this PR contains only runtime
enforcement.
## Test plan
- `just test -p codex-core-plugins` (287 tests)
- `just test -p codex-cli
plugin_list_ignores_implicit_system_marketplace_roots_without_manifests`
- `cargo check -p codex-cli -p codex-app-server --tests`
## 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
Marketplace source deserialization treated `{"source":"npm", ...}` as
unsupported. The loader logged and skipped the entry, so npm-backed
plugins never appeared in `plugin list --available` and `plugin add`
returned "plugin not found".
Codex plugins are installed from a plugin root, not from an npm
dependency tree. For npm-backed marketplace entries, Codex should fetch
the published package contents without running package scripts or
installing unrelated dependencies.
## What changed
- Add `npm` marketplace plugin sources with `package`, optional semver
`version` or version range, and optional HTTPS `registry`.
- Reject unsafe npm source fields before materialization, including
invalid package names, non-semver version selectors, plaintext or
credential-bearing registry URLs, and registry query/fragment data.
- Materialize npm plugins with `npm pack --ignore-scripts`, then unpack
the resulting tarball through the existing hardened plugin bundle
extractor.
- Enforce npm archive and extracted-size limits, require the standard
npm `package/` archive root, and verify the extracted `package.json`
name matches the requested package before installing.
- Keep plugin listings, install-source descriptions, CLI JSON/human
output, app-server v2 `PluginSource`, TUI source summaries, regenerated
schema fixtures, and app-server documentation in sync.
## Impact
Marketplaces can distribute Codex plugins from public or configured
private HTTPS npm registries using the same install flow as existing
materialized plugin sources. `npm` must be available on `PATH` when an
npm-backed plugin is installed.
Fixes#27831
## Validation
- `just write-app-server-schema`
- `just test -p codex-core-plugins -p codex-app-server-protocol -p
codex-app-server -p codex-cli`
- npm/schema/core-plugin coverage passed in the run.
- The full focused command finished with `1739 passed`, `11 failed`, and
`6 timed out`; the failures were unrelated local app-server environment
failures from `sandbox-exec: sandbox_apply: Operation not permitted`
plus one missing `test_stdio_server` helper binary.
- Installed an npm-published Codex plugin package through a throwaway
local marketplace and throwaway `CODEX_HOME` to exercise the real npm
materialization path end to end.
## Summary
- distinguish expired, non-refreshable stored MCP OAuth credentials from
first-time missing credentials
- carry a typed `failureReason: "reauthenticationRequired"` on the
existing `mcpServer/startupStatus/updated` notification only when user
action is required
- keep the public MCP auth-status API unchanged and regenerate the
app-server protocol schemas and documentation
## Why
An MCP server with an expired access token and no usable refresh token
currently fails startup without giving clients a reliable, typed
recovery signal.
The existing startup-status notification is the natural place to carry
this state. Its nullable `failureReason` keeps the recovery reason
attached to the failed startup transition without adding a one-off
notification. Internally, Codex distinguishes first-time login from
reauthentication and emits the reason only when the startup error itself
requires authentication.
## User impact
App clients can prompt an existing user to reconnect an MCP server when
automatic recovery is impossible by handling a failed
`mcpServer/startupStatus/updated` notification whose `failureReason` is
`reauthenticationRequired`. Starting, ready, cancelled, unrelated
failures, and first-time setup carry no reauthentication reason.

## Why
`codex sandbox` accepts a single named permissions profile, so the
existing plural `--permissions-profile` spelling is misleading. The
canonical flag and its help text should use the singular form without
breaking scripts that already use the old spelling.
## What changed
- Make `--permission-profile` the canonical flag for all sandbox
backends.
- Keep `--permissions-profile` as a hidden backwards-compatible alias.
- Cover the canonical spelling, legacy alias, and help visibility with
regression tests.
## Testing
Ran `just c sandbox --help` and verified I saw:
```shell
-P, --permission-profile <NAME>
Named permissions profile to apply from the active configuration stack
```
## Summary
- Record bounded connection, request, and process lifecycle metrics.
- Report active gauges from callbacks on every collection, including
delta exports.
- Serialize active-count updates so concurrent starts and finishes
cannot publish stale values.
- Serialize process exit, explicit termination, and shutdown through the
process registry so exactly one completion result wins.
- Keep the implementation small with single-owner RAII guards and one
real OTLP/HTTP integration test using the existing `wiremock`
dependency.
## Root cause
Process exit and session shutdown previously used cloned completion
state. That avoided duplicate emission, but it duplicated lifecycle
ownership and made the ordering harder to reason about. The process
registry mutex already defines the lifecycle ordering, so the final
implementation stores the metric guard and termination flag directly on
the process entry. Whichever path claims the entry first owns the
completion result.
Production metric export uses delta temporality. Event-only synchronous
gauge recordings disappear after the next collection when no count
changes, so active counts now use observable callbacks that report
current state on every collection.
The cleanup also removes the constant `result="accepted"` connection
tag, redundant route and response assertions, a custom HTTP collector,
and fallback initialization machinery that did not add behavior.

## Why
#28522 routes selected-plugin HTTP MCP traffic through the owning
executor, but OAuth bootstrap and refresh still used host-local clients.
Executor-only servers therefore cannot complete discovery or login
through the same network boundary as the MCP connection.
## What changed
- adapt `codex_exec_server::HttpClient` to RMCP 1.8's `OAuthHttpClient`
contract
- let RMCP own discovery, dynamic registration, PKCE, token exchange,
and refresh
- route auth status, persisted-token startup, and app-server login
through the server runtime while preserving the existing local discovery
path
- add optional `threadId` to `mcpServer/oauth/login` and echo it in the
completion notification
- implement RMCP's redirect policy and 1 MiB OAuth response limit over
executor HTTP
- cover selected-thread OAuth discovery and login through an
executor-only route
Depends on #28522.
## Why
MCP authentication has distinct OAuth and ChatGPT-session flows.
Representing that choice as `use_chatgpt_auth` makes one flow implicit
and allows the configuration model to express the distinction only
through a boolean.
ChatGPT credential forwarding also needs a first-party trust boundary. A
configurable `chatgpt_base_url` controls routing, but must not grant an
MCP server permission to receive session credentials.
This change builds on #29733, where the boolean was introduced.
## What changed
- Replace `use_chatgpt_auth` with an `auth` field backed by the
exhaustive `McpServerAuth` enum.
- Support `auth = "oauth"` and `auth = "chatgpt"`, with OAuth remaining
the default.
- Trust only the origin derived from the existing hardcoded
`CHATGPT_CODEX_BASE_URL` when granting ChatGPT auth to an MCP server.
- Keep configured bearer tokens and authorization headers ahead of the
selected authentication flow.
- Update config writers, schema output, fixtures, and integration-test
setup to use the enum.
## Verification
Integration coverage exercises the complete streamable HTTP startup path
in two independent configurations:
- A directly constructed MCP configuration verifies that matching an
overridden `chatgpt_base_url` does not grant ChatGPT auth.
- A persisted `config.toml` containing an attacker-controlled
`chatgpt_base_url` and `auth = "chatgpt"` verifies the same boundary
through normal config parsing.
Both tests complete MCP initialization and tool listing and assert that
the full captured request sequence contains no authorization headers.
Separate integration coverage verifies that configured authorization
takes precedence over ChatGPT auth.
## Why
ChatGPT session authentication was inferred from the reserved Codex Apps
server name. That couples credential routing to Codex Apps-specific
behavior and prevents other MCP endpoints hosted by ChatGPT from
explicitly using the current session.
The opt-in also needs a clear security boundary: an arbitrary MCP
configuration must not be able to redirect ChatGPT credentials to
another origin.
## What changed
- Add `use_chatgpt_auth` to HTTP MCP server configuration, defaulting to
`false`.
- Honor the setting only when the parsed server URL has the same HTTP(S)
origin as the configured `chatgpt_base_url`; otherwise remove the
capability before startup.
- Resolve bearer tokens and static or environment-backed authorization
headers before selecting authentication, with configured authorization
taking precedence over ChatGPT session auth.
- Enable the setting for the built-in Codex Apps and hosted plugin
runtime endpoints while keeping Codex Apps caching and tool
normalization scoped to the reserved server.
- Persist the setting through MCP config rewrite paths and expose it in
the generated config schema.
- Load the current login state for `codex mcp list` so reported auth
status matches runtime behavior.
## Verification
Core integration coverage exercises the complete streamable HTTP MCP
startup path and verifies that:
- a same-origin opted-in server receives the current ChatGPT access
token;
- an explicitly configured authorization header takes precedence;
- a different-origin server completes MCP initialization and tool
listing without receiving any ChatGPT authorization header.
## Why
Users who run Codex remote control through daemon mode can keep the
daemon running, but they do not have a CLI path to mint the short-lived
manual pairing code needed to connect another device. Without this
command, they need to speak app-server JSON-RPC directly.
Related: #25675
## What Changed
- Added `codex remote-control pair`, which connects to the existing
daemon control socket and calls `remoteControl/pairing/start` with
`manualCode: true`.
- Kept the command non-lifecycle-mutating: it does not start, enable, or
restart the daemon.
- Human output labels the manual code as `Pairing code: ...`; `--json`
preserves the full pairing response.
- Added daemon socket-client, CLI formatting, and parser coverage.
## Verification
- `remote_control_client::tests::start_pairing_requests_manual_code`
verifies the daemon client sends `{ "manualCode": true }` and parses the
complete response.
-
`remote_control_cmd::tests::remote_control_pairing_human_output_labels_the_manual_code`
verifies the human-facing output.
## Why
Executor-owned plugin roots are `PathUri`, but MCP config normalization
still converts them into a native `Path` using the app-server host's
rules. Relative `cwd` values can therefore resolve against the wrong
filesystem when host and executor path conventions differ.
This PR keeps executor MCP paths URI-native until the selected
environment launches the server, while retaining the existing host
parser behavior.
## What changed
- Keep one shared MCP normalization path with narrow host-`Path` and
executor-`PathUri` entrypoints.
- Preserve native host resolution for locally installed plugin MCP
configs.
- For executor configs, default `cwd` to the plugin root and resolve
relative working directories with the root URI's path convention.
- Accept explicit executor `file:` URIs only when they remain within the
selected plugin root.
- Preserve the selected environment id and existing remote
environment-variable ownership rules.
- Route the executor plugin provider through the URI-native entrypoint
without converting the root on the host.
- Ensure `codex doctor` does not probe executor-owned stdio commands or
foreign working directories on the host.
- Cover foreign Windows roots, relative and absolute executor working
directories, traversal rejection, runtime resolution, and doctor
behavior.
```text
plugin root: file:///C:/plugins/demo
configured cwd: scripts
|
v
resolved cwd: file:///C:/plugins/demo/scripts
|
v
launch through the selected executor
```
No new provider or filesystem abstraction is introduced.
## Stack
1. #29614 — add lexical `PathUri` containment.
2. #29620 — share URI-native manifest path resolution.
3. #28918 — keep selected plugin roots and resources URI-native.
4. #29626 — load executor skills without host path conversion.
5. **This PR** — resolve executor MCP working directories without host

## Why
Managed marketplace source requirements only become effective when every
local marketplace mutation path applies the same admission decision.
This change centralizes that decision so CLI, app-server, and
external-agent migration flows cannot add, install from, or refresh a
disallowed source.
## What changed
- Match exact normalized Git repository URLs with an optional exact
`ref`.
- Match Git hosts with managed regular expressions.
- Match local marketplaces by exact absolute path.
- Preserve the expected path/name boundary for managed OpenAI
marketplaces.
- Enforce source admission during marketplace add, plugin install, and
configured Git marketplace upgrade.
- Continue upgrading independent marketplaces when one source is
rejected and return a per-marketplace error.
- Load the effective requirements stack at CLI, app-server, and
external-agent migration entry points.
This PR does not filter already configured marketplaces at runtime; that
remains in draft follow-up #29691.
## Stack
This is PR 2 of 3 and is based on #29690, which introduces the
requirements data shape and merge behavior.
## Test plan
- Source matcher coverage for Git URL/ref, host-pattern, local-path, and
managed marketplace cases.
- Marketplace add and plugin install coverage for allowed and rejected
sources.
- Marketplace upgrade coverage for rejection and per-marketplace
continuation.
## Why
Authentication mode is a domain concept used by login, model selection,
telemetry, and transports. Keeping the canonical type in app-server
protocol forces those lower-level crates to depend on an unrelated wire
API.
## What changed
- Added canonical `codex_protocol::auth::AuthMode` domain values.
- Kept the app-server wire DTO unchanged and added an explicit app-side
conversion.
- Removed production app-server-protocol dependencies from login,
model-provider-info, models-manager, and otel call paths.
## Stack
This is PR 2 of 6, stacked on [PR
#29714](https://github.com/openai/codex/pull/29714). Review only the
delta from `codex/split-json-rpc-protocols`. Next: [PR
#29722](https://github.com/openai/codex/pull/29722).
## Validation
- Auth and login coverage passed in the focused protocol/domain test
run.
- App-server account and auth conversion coverage passed.
## Why
Filesystem helpers intentionally run with a minimal environment that
excludes proxy variables. After filesystem operations started using the
Windows sandbox wrapper, the wrapper derived an empty proxy
configuration from that helper environment and compared it with the
persistent sandbox setup marker. When the marker contained proxy ports,
every filesystem operation appeared to require a firewall update, which
could launch elevated setup, show a UAC or loader dialog, and fail
operations such as `apply_patch` with error 1223.
Filesystem helpers do not use network access, so they should preserve
the proxy/firewall state established by normal sandboxed process
launches.
## What changed
- Add an explicit Windows sandbox proxy-settings mode for reconciling or
preserving persistent proxy state.
- Use preserve mode for filesystem helpers while normal process launches
continue to reconcile proxy settings from their environment.
- Carry the selected proxy state consistently through setup validation,
elevated setup, and non-elevated ACL refreshes.
- Cover wrapper argument propagation and marker-derived proxy
preservation.
## Validation
- `cargo build -p codex-cli --bin codex`
- `just test -p codex-windows-sandbox
preserving_proxy_settings_uses_the_existing_marker`
- `just test -p codex-windows-sandbox windows_wrapper_args_round_trip`
- `just test -p codex-windows-sandbox
setup_request_prefers_explicit_proxy_settings`
- `just test -p codex-sandboxing transform_for_direct_spawn_windows`
- `just test -p codex-exec-server fs_sandbox::tests`
- Ran the same sandboxed `fs/writeFile` reproduction against published
`0.142.0-alpha.6` and the new CLI. The published CLI launched elevated
setup and failed with `ShellExecuteExW ... 1223`; the new CLI completed
without elevation.
Related to #28359.
## Why
Managed network configures commands to use local HTTP and SOCKS proxies.
For commands delegated to the exec server, the proxy environment and the
sandbox policy were prepared separately. On macOS, that meant a command
could receive `HTTPS_PROXY=http://127.0.0.1:43123` while Seatbelt still
denied access to port `43123`.
## What changed
`NetworkProxy` now prepares the command environment and sandbox context
together from the same runtime snapshot:
```text
Prepared managed network
├── command environment: HTTPS_PROXY=http://127.0.0.1:43123
└── sandbox context: allow outbound to 127.0.0.1:43123
```
That context travels with remote exec requests. The exec server
preserves the managed proxy and CA environment, and macOS Seatbelt
allows only the prepared loopback proxy ports without enabling broad
network access or local binding.
The protocol field is optional and the existing enforcement flag remains
in place, preserving compatibility with callers that do not send the new
context.
## Summary
- let `codex sandbox` accept the JSON value from
`codex/sandbox-state-meta`
- require the payload `permissionProfile` instead of falling back to
ambient permissions
- reuse the existing macOS, Linux, and Windows launch paths, treating
external sandbox state conservatively as read-only
- let opaque forwarders add runtime read roots and disable direct
network access without decoding the payload
Builds on #29113, which is now on `main`.
## Tests
- `just test -p codex-cli debug_sandbox::tests`
- `cargo build -p codex-rmcp-client --bin test_stdio_server`
- `just test -p codex-core
stdio_mcp_tool_call_includes_sandbox_state_meta`
- `just test -p codex-mcp`
- `just fmt`
## Why
Remote stdio MCP servers can run in an environment whose path convention
differs from the Codex host. A Windows cwd such as
`C:\Users\openai\share` is absolute for the executor but was rejected by
a POSIX orchestrator.
Built on #29501, now merged, which only clarifies the host-native
`PathUri` constructor name.
## What changed
- Deserialize MCP cwd values as `LegacyAppPathString` so config does not
apply host path rules.
- Interpret that spelling as host-native for local launches and convert
it to `PathUri` at executor launch.
- Skip host filesystem and command resolution checks for remote stdio in
`codex doctor`.
- Add host-independent config and executor-boundary coverage using the
foreign path convention for each test platform.
## Validation
- `just test -p codex-utils-path-uri -p codex-config -p codex-mcp -p
codex-rmcp-client` (408 passed)
- `just test -p codex-cli -p codex-rmcp-client` (372 passed)

## Summary
Stacked on #26706.
Adds the shared auth/system-proxy contract that later platform resolver
PRs plug into. This PR moves Codex-owned auth and startup HTTP clients
through a common route-aware boundary, but does not yet add Windows or
macOS system proxy resolution.
The default path remains unchanged when `respect_system_proxy` is absent
or disabled.
## Implementation
- Adds `codex-client/src/outbound_proxy.rs` with the shared
route-selection model:
- `OutboundProxyConfig`;
- `ClientRouteClass`;
- `RouteFailureClass`;
- `build_reqwest_client_for_route`.
- Preserves the existing reqwest/default-client behavior when no route
config is supplied.
- Uses the fixed MVP routing policy when route config is supplied:
platform system/PAC/WPAD discovery, then explicit env proxy variables,
then direct connection.
- Keeps platform-specific system discovery behind the shared client
boundary. This PR provides the contract and fallback behavior; later
resolver PRs plug in Windows and macOS discovery.
- Adds `login::AuthRouteConfig` so auth call sites depend on a small
policy type instead of platform resolver details.
- Maps the resolved `Config.respect_system_proxy` boolean into
`AuthRouteConfig` for auth-owned clients.
- Wires the route config through browser login, device-code login,
access-token login, login status, logout/revoke, token refresh, API-key
exchange, app-server account login, TUI/app startup, cloud-config
bootstrap, cloud tasks, plugin auth, and exec startup config loading.
## End-user behavior
- No behavior changes by default.
- When `respect_system_proxy = true`, auth-owned clients opt into the
shared route-aware client path.
- On platforms without a resolver implementation in this PR, system
discovery is unavailable and the route-aware path falls back to explicit
env proxy handling, then direct connection.
- Custom CA handling remains separate from proxy route selection and
still runs through the shared client builder.
- No proxy URLs, PAC contents, or resolved platform details are exposed
through the public config surface introduced here.
## Tests
Adds or updates coverage for:
- preserving default auth-client fallback behavior when no route config
is provided;
- injected environment-proxy fallback without mutating process
environment;
- existing login-server E2E flows using explicit `auth_route_config:
None` to guard unchanged default behavior;
- updated auth manager, login, logout, cloud-config, startup, and
plugin-auth call sites passing route config explicitly.
## Summary
A cold-resumed subagent kept its durable thread ID but could receive a
new session ID, splitting one agent tree across multiple sessions after
a restart.
Persist the root session ID in every rollout `SessionMeta`, carry it
through thread creation, and restore it before initializing the resumed
`Session` and `AgentControl`.
## Behavior
For a nested agent tree:
```text
root session R
parent thread P
child thread C
```
The child rollout stores:
```text
session_id: R
parent_thread_id: P
id: C
```
After a cold resume, the child still belongs to root session `R` while
its immediate parent remains `P`. The integration coverage uses distinct
values for all three IDs so it catches restoring the session from
`parent_thread_id`.
## Legacy rollouts
Previous rollouts have `id` but no `session_id`. `SessionMetaLine`
deserialization treats a missing `session_id` as `id`, keeping those
files readable, listable, and resumable. When a legacy subagent is
resumed through its root, that synthesized child ID no longer overrides
the inherited root-scoped `AgentControl`. New rollouts always persist
the explicit root session ID.
Stacked on #28766.
## Why
Network approvals are environment-scoped: allowing a host in one
execution environment should not allow the same host in another
environment.
#28766 adds the inert IDs and constructor plumbing. This PR applies the
behavior on top.
## What changed
- Route managed network traffic through per-environment HTTP and SOCKS
proxy listeners.
- Stamp HTTP, HTTPS CONNECT, SOCKS TCP, and SOCKS UDP policy requests
with the source environment at the proxy boundary.
- Carry the selected execution environment through shell, unified exec,
zsh-fork, and sandbox transform paths.
- Include the environment in pending, approved-for-session, and
denied-for-session network approval cache keys.
- Include the environment in approval IDs and approval prompts.
- Preserve legacy fallback for unattributed requests, but deny when
active-call attribution is ambiguous.
- Fail closed if an environment-specific proxy endpoint cannot be
prepared.
## Validation
- just fmt

## Stack
This is PR 2 of the simplified HAI single-run-task stack:
- [#19047](https://github.com/openai/codex/pull/19047) Agent Identity
assertion and task-registration primitives, including the shared
run-task helper used by existing Agent Identity JWT auth.
- [#19049](https://github.com/openai/codex/pull/19049)
Disabled-by-default ChatGPT auth opt-in that provisions/reuses persisted
Agent Identity runtime auth and its single run task.
- [#19051](https://github.com/openai/codex/pull/19051) Run-scoped
provider auth that uses one backend-owned task id for first-party
inference and compaction requests.
[#19054](https://github.com/openai/codex/pull/19054) collapsed out of
the active stack because the simplified design no longer needs a
separate background/control-plane task helper.
## Summary
This PR adds the disabled-by-default path for normal ChatGPT-login Codex
sessions to obtain Agent Identity runtime auth through the Codex
backend. Existing Agent Identity JWT startup mode remains a separate
path and does not require the feature flag.
What changed:
- adds the experimental `use_agent_identity` feature flag and config
schema entry
- adds an explicit `AgentIdentityAuthPolicy` so call sites choose
`JwtOnly` or `ChatGptAuth` instead of passing a bare boolean
- stores standalone Agent Identity JWT credentials separately from
backend-registered Agent Identity records
- persists the registered Agent Identity record, private key, and single
run task id in `auth.json` so process restarts reuse the same identity
- derives the agent/task registration base URL from ChatGPT/Codex auth
config while keeping JWT JWKS lookup separate
- provisions and caches ChatGPT-derived Agent Identity runtime auth when
`use_agent_identity` is enabled
- reuses the shared run-task registration helper from PR1 rather than
adding a second task-registration path
This PR intentionally does not switch model inference over to
`AgentAssertion` auth. The provider-auth integration lands in the next
PR.
## Testing
- `just test -p codex-login`
## Summary
- Initialize stderr tracing and the configured OpenTelemetry provider
for local and remote `codex exec-server` startup.
- Instrument the local and remote server entrypoints with a root runtime
span.
- Keep raw Noise environment, registration, and stream identifiers out
of exported spans while preserving them in local debug events.
- Keep telemetry setup in a focused CLI module instead of growing the
top-level command entrypoint.

[#19054](https://github.com/openai/codex/pull/19054) collapsed out of
the active stack because the simplified design no longer needs a
separate background/control-plane task helper.
## Summary
The simplified POC shape is one backend-owned task per Agent Identity
run. This PR makes the first layer match that final shape directly
instead of introducing task targets, caller-owned external task refs, or
intermediate wrappers that later PRs would need to undo.
What changed:
- keeps the `AgentAssertion` wire payload as `agent_runtime_id`,
`task_id`, `timestamp`, and `signature`
- exposes `register_agent_task` as the single task-registration helper
for both existing Agent Identity JWT auth and the ChatGPT-registration
path added later in the stack
- makes task registration send only the signed registration timestamp;
the backend owns the returned opaque task id
- removes the unused target/task-kind/external-task-ref surfaces from
`codex-agent-identity`
- keeps Agent Identity JWT JWKS lookup separate from agent/task
registration URL derivation
- updates Agent Identity JWT auth to register one run task during auth
construction and share that task across cloned auth handles
This PR intentionally does not enable ChatGPT-derived Agent Identity.
That opt-in and config gate are added in the next PR.
## Testing
- `just test -p codex-agent-identity`
## Summary
- choose the local OpenAI curated marketplace manifest based on auth:
Codex backend auth gets the existing marketplace, direct provider auth
gets `api_marketplace.json`
- include Bedrock API key auth in the direct-provider API marketplace
path
- safely skip the API marketplace when `api_marketplace.json` is absent
## Validation
- `just fmt`
- `git diff --check origin/main...HEAD`
- CI should run the full validation
## Manual Testing
### - New api marketplace not available for API key sign
1. Safely not display anything from api marketplace

### - New api marketplace for API key sign in
1. Setup api_marketplace.json
```
{

```
2. Log in with API key, observe that only the defined plugin from
api_marketplace.json is available from "Codex Official" (outside of
local testing marketplaces)

## Notes
- `just test -p codex-core-plugins` was started locally before splitting
branches, but I stopped relying on local tests per follow-up and left
final validation to PR CI.
## 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.
## Stack
1. [openai/codex#26242](https://github.com/openai/codex/pull/26242):
Noise channel and relay transport
2. **[openai/codex#26245](https://github.com/openai/codex/pull/26245)**:
remote registration and runtime activation
