## What changed
- Select fresh authentication for each HTTP operation on eligible OpenAI MCP connections while preserving the connection's credential source and account network policy. Stop redirects when requests carry runtime assertions.
- Pass the owning thread's authentication and runtime context through app discovery, connector metadata, and trusted-access requests. Include the runtime authentication mode in MCP connection and tool-cache identities.
- Give resumed actors analytics clients bound to their own authentication context, and serialize stored-credential reloads with token refresh while preserving host-provided credentials.
## Testing
Add coverage for fresh request assertions, revoked account policies, redirect handling, resumed-actor isolation, and MCP uploads in dual-header and assertion-only modes.

Update `workspace_policy_change_rejects_pending_transient_auth_fallback` to
pass `None` for `cached_auth` and unwrap the `load_auth` result before
checking the fallback credentials.
GitOrigin-RevId: 09b7812f2f072389f9633de977e63edfa45186ed
## Why
A temporary external credential provider failure should not clear cached authentication or appear as a logout.
## What changed
Retain cached credentials after transient external auth failures when they still satisfy the current login and workspace restrictions. Advance the auth generation when the forced workspace policy changes so pending reloads cannot publish credentials validated against an outdated policy.
## Testing
Add regression tests for retaining credentials without auth change notifications during a transient failure, notifying watchers after recovery, rejecting credentials disallowed by a workspace policy change, and discarding a pending fallback validated before that change.
GitOrigin-RevId: 304f091f3b59d4840a8be09bf38671370e86abd8
## Why
Workspace switching rewrites claims returned by `get_token_data()`, so comparing those tokens with the stored refresh generation can fail to recognize an unfinished ChatGPT refresh.
## What changed
Compare tokens from the current auth JSON with the unsettled refresh generation, preserving detection when workspace claims differ from the original ID token.
## Testing
Extend the refresh cancellation regression test to cover a workspace switch that retains the original ID and refresh tokens.
GitOrigin-RevId: 097311e4cdc22cde875589ef616daf60c6b8ef80
## Why
Registration can time out while resolving credentials, before any request is sent. Treating this as a transport timeout prevents a safe retry. Credential resolution timeouts can also incorrectly quarantine credentials when no OAuth refresh exchange has started.
## What changed
- Classify registration deadlines reached before the first send as `RequestNotSent`, allowing the existing registration retry loop to recover. Preserve transport timeout handling once a request has been sent.
- Track unsettled ChatGPT refreshes in `AuthManager` from the start of the OAuth exchange through credential persistence. Cancellation while waiting for the refresh guard or reading credentials does not mark them as unsettled.
- Have the executor auth provider withhold credentials with an unsettled refresh. Preserve uncertainty after a cancelled exchange even if a later refresh fails, while allowing replacement credentials and successfully completed refreshes.
## Testing
Add regression coverage for registration and connection deadlines across auth stages, retrying registration after an unsent credential timeout, recovery after slow replacement PAT metadata, and cancellation before and during OAuth refresh.
GitOrigin-RevId: f4d7ec2db7f79b8d313f1ee52dbd441094856669
## Why
ChatGPT credentials can rotate while a remote executor is idle. Registry requests need to follow stored rotations without continuing after logout or switching the executor's identity. Concurrent refreshes must also avoid overwriting newer credentials.
## What changed
- Reload and validate ChatGPT credentials before registry requests, pinning the credential mode, account, user, and workspace policy. Reuse cached metadata for unchanged personal access tokens.
- Retry registration when temporary credential resolution failures prevent a request from being sent. Bound credential resolution and block reuse of a token generation whose refresh outcome is unknown.
- Restrict supported authentication modes before executor startup loads credentials or cloud configuration.
- Serialize persistent credential writes across cooperating processes and compare stored credentials before committing refreshed tokens.
- Replace `auth.json` atomically so overlapping readers see a complete document, preserving symlink targets and protecting file permissions, including Windows access controls.
## Testing
Add coverage for credential rotation, logout, identity changes, cancelled refresh callers, temporary metadata failures, registration retries, concurrent credential writes, and atomic file replacement.
GitOrigin-RevId: 6b210944bf8eba2f45bc27113f901d2c3cb06b48
## What changed
- Add `accountSession/list` and `accountSession/switch` for the active managed ChatGPT login, with optional workspace membership refresh.
- Validate membership and workspace policy, pause new turns, and unload running threads before switching credentials. Notify clients with `thread/closed` and `account/updated`; selecting the current workspace leaves threads running.
- Support browser sign-in for SSO through `allowBrowserLogin`, binding the callback to the requesting login and workspace. Require a separate sign-in for government workspaces.
- Preserve the selected workspace across token refresh and conditionally restore the previous workspace if routing validation fails. Guard credential writes against concurrent login or logout changes.
## Testing
Add app-server and auth tests covering workspace switching, credential preservation, policy and identity rejection, conditional rollback, stale sessions, and SSO callback validation.
GitOrigin-RevId: 1234abc33b71e69b66318da3e201fccc08867906
## Why
API keys with FedRAMP issuance markers previously used commercial endpoint defaults without a FedRAMP request header.
## What changed
- Recognize `sk-proj-fedramp-` and `sk-svcacct-fedramp-` prefixes as routing hints and send `X-OpenAI-Fedramp: true`, preserving the complete key for authentication.
- Select `https://gov.api.openai.com/v1` for default OpenAI API routing and `https://gov.chatgpt.com/backend-api/` for default ChatGPT backend requests, including model discovery and analytics.
- Preserve explicit endpoint overrides, including an explicitly configured commercial default URL.
- Resolve provider routing and authentication from the same credential snapshot, and apply key-dependent routing to realtime WebSocket startup.
## Testing
Add regression coverage for prefix recognition, unchanged key storage and authorization, provider credential precedence, endpoint overrides, credential rotation, model discovery, analytics routing, and realtime request preparation.
GitOrigin-RevId: a62576ce205c34e067532b8e6c0e431f87a157e2
## Why
An in-flight token refresh or auth reload can outlive a login change or logout. Its result must not overwrite credentials for a different login or restore stale cached auth.
## What changed
- Serialize in-process auth storage reads and writes that participate in credential updates.
- Verify the stored login before persisting refreshed tokens or agent identity records, while allowing older clients to drop login metadata when the refresh token still matches.
- Reject stale auth reload results using generation checks, and invalidate pending reads on logout even when the cache is already empty.
- Keep account grant reads strict when the keyring is unavailable, while preserving ordinary auth fallback behavior.
## Testing
Add regression coverage for stale reloads after logout, login replacement during refresh, legacy metadata loss, keyring recovery with rotated tokens, and refresh persistence failures.
GitOrigin-RevId: 01bce9ddbc3101de868adcda3370fcdc4eb70163
## Why
Token refresh needs the issuer and client ID used at login. Unverified token claims cannot establish that authority, and OAuth error bodies may echo credentials.
## What changed
- Save `oauth_provenance` and a new `login_owner_id` on browser and device-code login. Preserve the login identifier through token rotation.
- Refresh using the recorded issuer and client ID, retaining the existing endpoint override and fallback behavior for legacy records. Clear provenance when an override changes the endpoint or when a response without token rotation encounters a concurrently replaced refresh token.
- Keep both metadata fields optional for older records without inferring provenance from token claims.
- Remove backend token error details from structured logs and refresh error messages.
- Box large futures in token refresh, MCP initialization, and embedded app-server test startup to reduce surrounding async frame sizes.
## Testing
Add coverage for legacy record compatibility and metadata round trips, browser and device-code login persistence, refresh using recorded OAuth settings, metadata preservation through rotation, and provenance clearing for a superseded refresh token.
GitOrigin-RevId: b6b5d2fcbe2a284a171a242c1a17128af55f1024
## Why
Concurrent Linux test spawns can inherit writable descriptors for executable fixtures, preventing those fixtures from being executed even after the writing test closes its descriptor.
## What changed
Replace direct executable fixture writes and copies across the Rust tests with `codex_utils_cargo_bin::write_executable` and `copy_executable`. These existing helpers complete writes and copies in separate processes on Linux.
Remove the empty temporary inode before creating fake bubblewrap executables, and stage tampered bubblewrap bytes in a separate data file before copying them into the executable fixture. Add the required test dependencies.
GitOrigin-RevId: c875c83088731a4933ef1574e8d79d8cecc12f54
## Why
A provider auth command can fail during initial credential resolution, leaving
no cached authentication. A subsequent `401` should still give the configured
provider one bounded opportunity to recover.
## What changed
- Treat configured external authentication with an empty cache as eligible for
unauthorized recovery.
- Allow authority refresh to invoke the external provider when no prior auth is
cached, while preserving the existing requirements for managers without an
external provider.
## Testing
Added unit and client coverage for a provider command that fails initially and
succeeds during `401` recovery.
GitOrigin-RevId: 7cab9a03f90ce29b412be8fbd97b297acdad4482
## What changed
- Add the experimental `amazonBedrockAccessKeys` app-server login flow, persist its credentials in the configured auth store, and use them for SigV4-signed Bedrock requests.
- Report `bedrockAccessKeys` as a distinct auth mode and document access-key login alongside AWS profile and environment credential setup.
- Clear the selected Bedrock provider, AWS settings, and Bedrock-specific model on logout while leaving external AWS credentials and `.env` untouched.
- Reject managed access-key login when higher-precedence configuration would prevent its region or profile settings from taking effect.
## Testing
- Cover access-key login, storage, request signing, configuration conflicts, status reporting, and logout cleanup.
GitOrigin-RevId: bbf297887c6503d3651ceb2aad85c4d626e32723
## What changed
- Validate externally supplied header credentials against configured ChatGPT workspace restrictions using their `chatgpt-account-id` header.
- Reject header credentials with a missing or disallowed account ID, including credentials returned during refresh, without replacing the previously cached authentication.
- Document that identity headers must be bound to validated credentials because Codex uses them for managed authentication policy.
## Testing
- Add coverage for allowed, disallowed, and missing account IDs.
- Add coverage for rejecting a refresh that changes to a disallowed workspace.
GitOrigin-RevId: 3e3db2607cd8f9f1b8000472342e42e4b1cf00b2
## What changed
- Add a best-effort `network/policyDecision` notification for final domain and non-domain policy decisions made by executor-local proxies.
- Validate notifications against the active process on the controller and emit audit events with controller-trusted session and execution metadata.
- Reserve outbound RPC capacity so audit notifications cannot block control messages, and expose valid `chatgpt-account-id` header values for audit attribution.
## Testing
- Cover notification serialization, proxy decision capture, executor-to-controller delivery, trusted metadata handling, and reserved RPC capacity.
GitOrigin-RevId: a39f96a6b3d9401c03d54eaef5b9a6d3fe0da78b
## What changed
- Treat workload identity environment markers as an explicit authentication selection, even when another process credential is present.
- Return initialization errors from `AuthManager` and propagate them through commands and services instead of continuing with an unusable authentication state.
- Make `codex login status` validate workload identity, keep the TUI on an embedded app server for local workload identity, and reject workload identity in `codex mcp-server`, where it is unsupported.
## Testing
- Cover workload identity precedence and partial configuration errors.
- Verify login status reports an unreadable identity assertion and app-server routing enforces the supported workload identity topology.
GitOrigin-RevId: efc6b6b4cd4d61652617de82aaa3d7ffc75d6618
## What changed
- Use each `ExternalAuth` provider's error classification for resolve, refresh,
and validation failures.
- Allow runtime providers to be replaced, clearing any recorded permanent
refresh failure after the replacement resolves successfully.
- Preserve workload identity as immutable, host-managed authentication while
sharing external ChatGPT credentials through the process-local store.
## Testing
- Cover provider replacement after a permanent failure, provider-defined error
classification, workload identity immutability, and refreshed headers after
an unauthorized response.
GitOrigin-RevId: ec75cf9224dc82d3fd10063606c724e3b06fb1e7
## What changed
- Select workload identity authentication from `OPENAI_FEDERATION_RULE_ID` and
`OPENAI_IDENTITY_TOKEN_FILE`, while preserving explicit API key and access
token precedence.
- Adapt workload identity exchanges to the shared authentication manager and
reuse a compatible process-scoped session for token resolution and refresh.
- Reject incomplete, conflicting, or unsupported configurations and exchanged
tokens that change the authenticated subject.
- Classify exchange failures for authentication retry handling and invalidate
rejected cached tokens without discarding a newer concurrent exchange.
## Testing
- Cover configuration selection and validation, session reuse and conflicts,
identity-preserving refreshes, concurrent refreshes, and retry classification.
GitOrigin-RevId: 62afb514b4e0a59effb08f464ac929633462a71b
## What changed
- Add a host-owned external auth source that runtime account APIs cannot replace,
clear, or log out, and keep its credentials process-local instead of writing
them to auth storage.
- Let configured providers classify refresh failures. Preserve cached credentials
after permanent reload failures while retaining transient behavior for runtime
providers.
- Compare external ChatGPT token data when detecting auth changes so a refreshed
access token is applied to a retried request.
## Testing
- Cover configured-auth immutability, process-local storage, permanent reload
failures, runtime error classification, and refreshed headers after a `401`.
GitOrigin-RevId: c6d70a39325c8ba6ca65ae68e12b55609f00a876
## What changed
- Honor `CODEX_AGENT_IDENTITY_AUTHAPI_BASE_URL` and
`CODEX_AGENT_IDENTITY_JWKS_BASE_URL` when registering and verifying agent
identities.
- Normalize override values by trimming whitespace and trailing slashes.
- Preserve ChatGPT environment validation, while allowing a custom launcher
configuration when its ChatGPT and JWKS base URLs match and an AuthAPI
override is explicitly configured.
## Testing
Added coverage for explicit staging overrides, custom launcher compatibility,
and rejection of overrides that would bypass environment validation.
GitOrigin-RevId: c557c8167ec101c2993f65aad3fcb3bf25785d51
## Why
Authentication restrictions must apply before stored or environment-provided credentials can be used, including during bootstrap before cloud requirements are fetched.
## What changed
- Add local `requirements.toml` allowlists for login methods and ChatGPT workspaces. Ignore these fields in cloud-provided requirements.
- Combine managed workspace allowlists with existing workspace restrictions by intersection, and fail closed when the resulting policy permits no usable login method.
- Centralize policy checks in the authentication manager so CLI, TUI, app-server, external-auth, and credential-loading paths consistently reject disallowed authentication before token hydration or network requests.
## Testing
- Cover policy composition, workspace intersection, invalid stored and external credentials, bootstrap enforcement, and login endpoint restrictions.
GitOrigin-RevId: efef22b248f3c3333e9aa55423e539efa2d2dd48
## 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 managers should use the application's resolved HTTP client factory instead
of silently falling back to the transport's default proxy behavior.
## What changed
- Make `AuthRouteConfig` required when constructing an `AuthManager` or
`AuthConfig`.
- Pass each production caller's resolved routing configuration through without
wrapping it in an optional value.
- Add a test helper that explicitly selects the transport-default proxy policy
for callers that do not exercise custom routing.
GitOrigin-RevId: d89a3b1f8b5d4007650cdac0aae241c94d598580
## 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
## Summary
External auth had two paths: provider-command credentials were resolved
through `ExternalAuth`, while app-provided ChatGPT credentials were
installed separately and only used the provider for refresh.
`ExternalAuth` also declared an auth mode independently from the
`CodexAuth` value it returned, so the declaration and credentials could
disagree.
This change makes the provider-owned `CodexAuth` authoritative for
initial resolution, credential kind, and refresh.
- remove `ExternalAuth::auth_mode` and require providers to return their
current auth from `resolve`
- route external auth registration, resolution, and unauthorized refresh
through `AuthManager::set_external_auth`
- keep the last resolved credential with its provider so synchronous
consumers and unauthorized recovery observe the credential's actual mode
- make the app-server bridge own both initial and refreshed ChatGPT
credentials, and detach it on logout
- keep model listing free of auth-refresh side effects, including in
offline mode
Provider-command auth still follows its configured cache interval.
App-provided ChatGPT auth still asks the parent app once after a `401`
and retries the request once.
Stacked on #31355.
## Testing
- `just test -p codex-login`
- `just test -p codex-models-manager`
- focused `codex-app-server` tests for external login/logout,
unauthorized refresh, and workspace mismatch
## Summary
- refactor `ExternalAuth` to return `CodexAuth` directly
- remove the parallel `ExternalAuthTokens` wrapper
- preserve existing external bearer and app-server refresh behavior
This is a mechanical precursor refactor; it does not add auth
capabilities or change recovery behavior.

## Stack
This is PR 3 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

- [#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 moves Agent Identity usage into provider auth resolution. That
keeps `AgentAssertion` auth tied to first-party OpenAI provider requests
instead of applying a late session-wide override that could affect
local, custom, Bedrock, API-key, or external-bearer providers.
What changed:
- adds a small `ProviderAuthScope` struct carrying the run auth policy
and session source needed by provider-scoped auth resolution
- lets `Session` opt the existing `ModelClient` into `ChatGptAuth`
policy when `use_agent_identity` is enabled, without adding a second
model-client constructor
- resolves Agent Identity only for first-party OpenAI provider auth
paths
- uses the persisted run task id from the `AgentIdentityAuth` record to
build `AgentAssertion` auth for Responses requests
- routes shared request setup through scoped provider auth so unary
compact requests use the same run-task assertion path as inference turns
- keeps local/custom/Bedrock/env-key/external-bearer provider auth
unchanged
- lets missing run-task state surface through the existing model-request
error path instead of silently falling back to bearer auth
This PR intentionally does not create thread-scoped, target-scoped, or
background-scoped task identities. The run task is the only task Codex
registers in this POC shape.
## Testing
- `just test -p codex-model-provider`
- `just test -p codex-core client::tests::provider_auth_scope_uses`
- `just test -p codex-core remote_compact_uses_agent_identity_assertion`
## 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.
# Summary
Codex required every ChatGPT account to have an email address. A
service-account personal access token can return valid account metadata
without one, so PAT login failed while decoding the metadata response.
This change makes email optional in the account metadata type that owns
it and preserves that absence through authentication, provider account
state, the app-server API, generated clients, and TUI bootstrap.
Existing accounts with email addresses keep the same behavior.
## Behavior-changing call sites
| Call site | Behavior after this change |
| --- | --- |
| `login/src/auth/personal_access_token.rs` | PAT metadata accepts a
missing or null email and retains `None`. |
| `agent-identity/src/lib.rs` | Agent Identity JWT claims accept an
omitted email. |
| `login/src/auth/storage.rs` and `login/src/auth/agent_identity.rs` |
Stored and managed Agent Identity records carry `Option<String>`.
Deserialization maps the legacy empty-string sentinel to `None`. |
| `login/src/auth/manager.rs` | `get_account_email` returns the stored
option, and managed identity bootstrap no longer converts `None` to an
empty string. |
| `model-provider/src/provider.rs` and `protocol/src/account.rs` | A
ChatGPT provider account requires a plan type but may carry no email. |
| `app-server-protocol/src/protocol/v2/account.rs` | `account/read`
keeps the `email` field on the wire and returns `null` when the account
has no email. Generated TypeScript and JSON schemas describe a required,
nullable field. |
| `sdk/python/src/openai_codex/generated/v2_all.py` | The generated
Python `ChatgptAccount` model accepts `None` for email. |
| `tui/src/app_server_session.rs` | Email-less ChatGPT accounts
bootstrap normally, keep external feedback routing, omit account-email
telemetry, and display the plan in account status. |
## Design decisions
- Missing email remains `None` at every layer. The code never uses an
empty string as a substitute.
- The app-server response includes `"email": null` instead of omitting
the field. Clients retain a stable response shape.
- Plan type remains required for provider account state. This change
relaxes only the email assumption.
## Testing
Tests: affected test targets compile, scoped Clippy and formatting pass,
a focused TUI snapshot covers plan-only account status, real
before/after PAT login smoke covers metadata without email, app-server
smoke covers `account/read` with `email: null`, and a regression smoke
covers an existing email-bearing PAT. Unit tests run in CI.
## Evidence
Visual smoke evidence will be attached here.
## 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.

[#19054](https://github.com/openai/codex/pull/19054) collapsed out of
the active stack because the simplified design no longer needs a

## 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.

## 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`
## Why
Windows Credential Manager limits generic credential blobs to 2,560
bytes. Large serialized ChatGPT auth payloads can exceed that limit, so
keyring-mode CLI auth needs a backend that keeps only the encryption key
in the OS keyring and stores the payload in Codex's encrypted
local-secrets file.
This is the third PR in the encrypted-auth stack:
1. #27504 — feature and config selection
2. #27535 — auth-specific local-secrets namespaces
3. This PR — CLI auth implementation and activation
4. MCP OAuth implementation and activation
## What Changed
- Added encrypted CLI-auth storage using the `CliAuth` secrets
namespace.
- Preserved direct keyring storage for platforms/configurations where it
remains selected.
- Selected the backend consistently for login, logout, refresh,
device-code login, auth loading, and login restrictions.
- Threaded resolved bootstrap/full config through CLI, exec, TUI,
app-server account handling, cloud config, and cloud tasks.
- Removed stale `auth.json` fallback data after successful encrypted
saves and removed encrypted, direct-keyring, and fallback data during
logout.
- Added storage and integration coverage for both direct and encrypted
keyring modes.
MCP OAuth persistence is intentionally left to the next PR.
## Validation
- `just test -p codex-login` — 131 passed
- `just test -p codex-cli` — 280 passed
- `just test -p codex-app-server v2::account` — 25 passed
- `just test -p codex-cloud-config service` — 21 passed, 7 skipped
- `just fix -p codex-login`
- `just fix -p codex-cli`
- `just fmt`
## Summary
- serialize the remaining login tests that mutate or read the
process-global auth environment
- include Bedrock auth-manager tests in the existing `codex_auth_env`
serial group
## Root cause
The login unit-test binary runs tests concurrently. One test removed
`CODEX_ACCESS_TOKEN` without joining the existing serial group, while
several Bedrock tests constructed `AuthManager` and read that same
process-global environment outside the group. An interleaving could
restore a stale personal access token while another test was loading
file-backed auth, causing the observed mismatched `/whoami` request
count and related auth-state flakes.
## Verification
- `just fmt`
- `git diff --check`
- `bazel test //codex-rs/login:login-unit-tests --nocache_test_results
--runs_per_test=20 --test_output=errors` (20/20 passed)
- `just test -p codex-login` (135/135 passed)
## Summary
- validate a hydrated personal access token's workspace against
`forced_chatgpt_workspace_id` before persisting `codex login
--with-access-token`
- apply the same PAT-only check when restricted auth managers load
environment, ephemeral, or persisted credentials
- enforce PAT workspace restrictions in the existing central
login-restriction path
- leave Agent Identity and cloud bootstrap behavior unchanged
## Scope
This is intentionally the small PAT-only change. It does not attempt the
broader auth-manager/bootstrap unification; that needs separate design
work.

## Why
Codex needs to manage Amazon Bedrock API key credentials through the
existing auth lifecycle instead of introducing a separate auth manager
or provider-specific credential file. Treating Bedrock API key login as
a primary auth mode gives it the same persistence, keyring, reload, and
logout behavior as the existing OpenAI API key and ChatGPT modes.
The credential is valid only for the `amazon-bedrock` model provider.
OpenAI-compatible providers must reject this auth mode rather than
treating the Bedrock key as an OpenAI bearer token.
## What changed
- Added `bedrockApiKey` as an app-server `AuthMode` and
`CodexAuth::BedrockApiKey` as a primary `AuthManager` mode.
- Added `BedrockApiKeyAuth`, containing the API key and AWS region, to
the existing `AuthDotJson` payload stored in `$CODEX_HOME/auth.json` or
the configured keyring backend.
- Added `login_with_bedrock_api_key(...)`, parallel to
`login_with_api_key(...)`, which replaces the current stored login with
Bedrock credentials.
- Reused generic auth reload and logout behavior instead of adding a
Bedrock-specific auth manager or logout path.
- Updated login restrictions, status reporting, diagnostics, telemetry
classification, generated app-server schemas, and auth fixtures for the
new mode.
- Added explicit errors when Bedrock API key auth is selected with an
OpenAI-compatible model provider.
This PR establishes managed storage and auth-mode behavior. Routing the
managed key and region into Amazon Bedrock requests will be in follow-up
PRs.
## Summary
- add v2 personal access token support for `codex login
--with-access-token` and `CODEX_ACCESS_TOKEN`
- classify opaque `at-` tokens separately from legacy Agent Identity
JWTs
- hydrate required ChatGPT account metadata through AuthAPI
`/v1/user-auth-credential/whoami`
- use PATs directly as bearer tokens while preserving existing ChatGPT
account surfaces
- expose PAT-backed auth as the explicit `personalAccessToken`
app-server auth mode
## Implementation
PAT auth is intentionally small and stateless. Loading a PAT performs
one AuthAPI metadata request, stores the hydrated metadata in the
in-memory auth object, and redacts the secret from debug output. Legacy
Agent Identity JWT handling remains unchanged. The shared access-token
classifier lives in a private neutral module because it dispatches
between both credential types.
PAT hydration fails closed when AuthAPI omits any required metadata,
including email. Hydrated metadata is intentionally not persisted:
startup performs a live `whoami` preflight so revoked tokens or changed
account metadata are not accepted from a stale cache.
## Workspace restriction scope
This change intentionally does **not** apply
`forced_chatgpt_workspace_id` to PAT authentication. The setting is a
client-side config guardrail, not an authorization boundary, and PAT
does not currently require workspace-ID parity. The PAT login and
`CODEX_ACCESS_TOKEN` paths therefore validate through AuthAPI without
threading workspace-restriction state through access-token loading.
Existing workspace checks for non-PAT auth remain on their established
paths.
## App-server compatibility
The public app-server `AuthMode` is shared across v1 and v2, and
PAT-backed auth reports `personalAccessToken` through both APIs.
Following human review, this intentionally removes the temporary v1
compatibility mapping that reported PATs as `chatgpt`; the deprecated v1
API is kept in parity with v2 rather than maintaining a separate closed
enum. Clients with exhaustive auth-mode handling in either API version
must add the new case and should generally treat it as ChatGPT-backed
unless they need PAT-specific behavior.
The v1 auth-status response still omits the raw PAT when `includeToken`
is requested because that response cannot carry the account metadata
needed to reuse the credential safely. Persisted PAT auth also omits the
new enum value so older Codex builds can deserialize `auth.json` and
infer PAT auth from the credential field after a rollback.
## Validation

- `CARGO_INCREMENTAL=0 just fix -p codex-login -p

- `just fmt`
- `git diff --check`
The broader `codex-tui` suite previously compiled and ran 2,834 tests.
Three unrelated environment-sensitive guardian/IDE-socket tests failed
after retries; the PAT-relevant TUI coverage passed.
## Summary
This change lets `forced_chatgpt_workspace_id` accept multiple workspace
IDs instead of a single value.
It keeps the existing config key name, adds backward-compatible parsing
for a single string in `config.toml`, and normalizes the setting into an
allowed workspace list across login enforcement, app-server config
surfaces, and local ChatGPT auth helpers.
## Why
Workspace-restricted deployments may need to allow more than one ChatGPT
workspace without dropping the guardrail entirely.
## Server-side impact
Codex's local server and app-server protocol needed changes because they
previously assumed a single workspace ID. The local login flow now
matches the auth backend interface by sending the allowed workspace list
as a single comma-separated `allowed_workspace_id` query parameter.
## Validation
This was tested with:
- A single workspace config
- With multi-workspace configs
- With multiple workspaces in the config
- The user only being a part of a subset of them
All were successful.
Automated coverage:
- `cargo test -p codex-login`
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-tui local_chatgpt_auth`
- `cargo test --locked -p codex-app-server
login_account_chatgpt_includes_forced_workspace_allowlist_query_param`
## Why
The external startup/login surface for this auth path should talk about
an access token instead of exposing the internal Agent Identity
terminology. Users should pass `CODEX_ACCESS_TOKEN` or pipe a token into
`codex login --with-access-token`; the old external env/flag spellings
are removed so there is only one supported user-facing path.
## What Changed
- Added `CODEX_ACCESS_TOKEN` as the supported environment variable for
this auth path.
- Added `codex login --with-access-token` as the supported stdin-based
login command.
- Removed the legacy `CODEX_AGENT_IDENTITY` env-var fallback and hidden
`--with-agent-identity` CLI alias.
- Updated CLI error, status, and stdin prompts to use access-token
language.
- Added coverage for access-token env loading, CLI login failure
behavior, and renamed login status text.
## Validation
- `cargo test -p codex-login`
- `cargo test -p codex-cli`
- `just fix -p codex-login`
- `just fix -p codex-cli`
## Why
Agent Identity sessions can represent Business and Enterprise ChatGPT
workspaces, but cloud requirements were skipped before fetch. That meant
workspace-managed requirements were not loaded for Agent Identity even
when the JWT carried the same account identity and plan information that
normal ChatGPT token auth exposes.
This PR now sits on top of the Agent Identity stack through
[#19764](https://github.com/openai/codex/pull/19764). Because
[#19763](https://github.com/openai/codex/pull/19763) moved task
registration into Agent Identity auth loading, cloud requirements no
longer needs a separate runtime-initialization step before building the
backend client.
## What changed
- Stop skipping `CodexAuth::AgentIdentity` in the cloud requirements
loader.
- Share the cloud requirements eligibility check between startup load
and background cache refresh.
- Rely on eagerly loaded Agent Identity auth so backend requests can
attach task-scoped `AgentAssertion` headers.
- Decode Agent Identity JWT `plan_type` as the auth-layer plan type,
then convert it through a shared `auth::PlanType` -> `account::PlanType`
mapping.
- Add the missing serde alias for the `education` plan string and add
coverage for raw Agent Identity plan aliases such as `hc` and
`education`.
## Testing
- `cargo test -p codex-agent-identity -p codex-login -p
codex-cloud-requirements -p codex-protocol`
## Summary
AgentIdentity auth previously registered the process task lazily behind
a `OnceCell`. That meant the auth object could be constructed before its
runtime task binding was known.
This PR makes AgentIdentity auth load the runtime task at auth load time
and stores the resulting process task id directly on the auth object.
The model-provider call path can then read a concrete task id instead of
handling a missing lazy value.

loading and stores `process_task_id`. |

## Design decisions
AgentIdentity auth now treats task registration as part of constructing
a usable auth object. That matches how callers use the value: once auth
is present, the model-provider path expects the task-scoped assertion
data to be ready.
## Testing
Tests: targeted Rust auth test compilation, formatter, scoped Clippy

## Summary
Auth loading used to expose synchronous construction helpers in several
places even though some auth sources now need async work. This PR makes
the auth-loading surface async and updates the callers to await it.
This is intentionally only plumbing. It does not change how
AgentIdentity tokens are decoded, how task runtime ids are allocated, or
how JWT signatures are verified.

## Summary
This PR lets programmatic AgentIdentity users provide one token through
either stdin login or environment auth.
`codex login --with-agent-identity` reads an Agent Identity JWT from
stdin, validates that it has the required claims, and stores that token
as the `agent_identity` value in `auth.json`. The file format is
token-only; the decoded account and key fields are runtime state, not
hand-authored auth.json fields.
The Agent Identity JWT claim shape and decoder live in
`codex-agent-identity`; `codex-login` only owns env/storage precedence
and conversion into `CodexAuth::AgentIdentity`.
When env auth is enabled, `CODEX_AGENT_IDENTITY` can provide the same
JWT without writing auth state to disk. `CODEX_API_KEY` still wins if
both env vars are set.

## Summary
This PR adds `CodexAuth::AgentIdentity` as an explicit auth mode.
An AgentIdentity auth record is a standalone `auth.json` mode. When
`AuthManager::auth().await` loads that mode, it registers one
process-scoped task and stores it in runtime-only state on the auth
value. Header creation stays synchronous after that because the task is
initialized before callers receive the auth object.
This PR also removes the old feature flag path. AgentIdentity is
selected by explicit auth mode, not by a hidden flag or lazy mutation of
ChatGPT auth records.
Reference old stack: https://github.com/openai/codex/pull/17387/changes
## Design Decisions
- AgentIdentity is a real auth enum variant because it can be the only
credential in `auth.json`.
- The process task is ephemeral runtime state. It is not serialized and
is not stored in rollout/session data.
- Account/user metadata needed by existing Codex backend checks lives on
the AgentIdentity record for now.
- `is_chatgpt_auth()` remains token-specific.
- `uses_codex_backend()` is the broader predicate for ChatGPT-token auth
and AgentIdentity auth.

## Summary
This PR fully reverts the previously merged Agent Identity runtime
integration from the old stack:
https://github.com/openai/codex/pull/17387/changes
It removes the Codex-side task lifecycle wiring, rollout/session
persistence, feature flag plumbing, lazy `auth.json` mutation,
background task auth paths, and request callsite changes introduced by
that stack.
This leaves the repo in a clean pre-AgentIdentity integration state so
the follow-up PRs can reintroduce the pieces in smaller reviewable
layers.

## Testing
Tests: targeted Rust checks, cargo-shear, Bazel lock check, and CI.
This is the second cleanup in the await-holding lint stack. The
higher-level goal, following https://github.com/openai/codex/pull/18178
and https://github.com/openai/codex/pull/18398, is to enable Clippy
coverage for guards held across `.await` points without carrying broad
suppressions.
The stack is working toward enabling Clippy's
[`await_holding_lock`](https://rust-lang.github.io/rust-clippy/master/index.html#await_holding_lock)
lint and the configurable
[`await_holding_invalid_type`](https://rust-lang.github.io/rust-clippy/master/index.html#await_holding_invalid_type)
lint for Tokio guard types.
Several existing fields used `tokio::sync::Mutex<()>` only as
one-at-a-time async gates. Those guards intentionally lived across
`.await` while an operation was serialized. A mutex over `()` suggests
protected data and trips the await-holding lint shape; a single-permit
`tokio::sync::Semaphore` expresses the intended serialization directly.
## What changed
- Replace `Mutex<()>` serialization gates with `Semaphore::new(1)` for
agent identity ensure, exec policy updates, guardian review session
reuse, plugin remote sync, managed network proxy refresh, auth token
refresh, and RMCP session recovery.
- Update call sites from `lock().await` / `try_lock()` to
`acquire().await` / `try_acquire()`.
- Map closed-semaphore errors into the existing local error types, even
though these semaphores are owned for the lifetime of their managers.
- Update session test builders for the new
`managed_network_proxy_refresh_lock` type.
## Verification
- The split stack was verified at the final lint-enabling head with
`just clippy`.

## Summary
Introduces a single background/control-plane agent task for ChatGPT
backend requests that do not have a thread-scoped task, with
`AuthManager` owning the default ChatGPT backend authorization decision.
Callers now ask `AuthManager` for the default ChatGPT backend
authorization header. `AuthManager` decides whether that is bearer or
background AgentAssertion based on config/internal state, while
low-level bootstrap paths can explicitly request bearer-only auth.
This PR is stacked on PR4 and focuses on the shared background task auth
plumbing plus the first tranche of backend/control-plane consumers. The
remaining callsite wiring is split into PR4.2 to keep review size down.
## Stack
- PR1: https://github.com/openai/codex/pull/17385 - add
`features.use_agent_identity`
- PR2: https://github.com/openai/codex/pull/17386 - register agent
identities when enabled
- PR3: https://github.com/openai/codex/pull/17387 - register agent tasks
when enabled
- PR3.1: https://github.com/openai/codex/pull/17978 - persist and
prewarm registered tasks per thread
- PR4: https://github.com/openai/codex/pull/17980 - use task-scoped
`AgentAssertion` for downstream calls
- PR4.1: this PR - introduce AuthManager-owned background/control-plane
`AgentAssertion` auth
- PR4.2: https://github.com/openai/codex/pull/18260 - use background
task auth for additional backend/control-plane calls
## What Changed
- add background task registration and assertion minting inside
`codex-login`
- persist `agent_identity.background_task_id` separately from
per-session task state
- make `BackgroundAgentTaskManager` private to `codex-login`; call sites
do not instantiate or pass it around
- teach `AuthManager` the ChatGPT backend base URL and feature-derived
background auth mode from resolved config
- expose bearer-only helpers for bootstrap/registration/refresh-style
paths that must not use AgentAssertion
- wire `AuthManager` default ChatGPT authorization through app listing,
connector directory listing, remote plugins, MCP status/listing,
analytics, and core-skills remote calls
- preserve bearer fallback when the feature is disabled, the backend
host is unsupported, or background task registration is not available
