## What changed
Allow `model_providers.<id>.gateway_oauth.credential_export` to supply a gateway access token instead of browser OAuth. Run the configured command on first use, cache its token in memory, and deliver it through the configured header or cookie. Export failures surface directly, and command-backed providers do not require an OAuth session.
Require mutually exclusive OAuth and exporter settings, same-origin model catalog access, and rejection of HTTP redirects for command-backed gateway credentials. Share the bounded, timeout-controlled command runner with AWS credential export.
## Testing
Add tests for inference and model listing without OAuth, token caching and recovery after invalid output, preservation of primary authentication, and rejection of mixed OAuth/exporter configuration.

## What changed
- Advance the pinned `tokio-tungstenite` and `tungstenite` fork revisions and update the Cargo and Bazel lockfiles.
- Use `OAuthCredentialsStore::File` in the gateway credential test to avoid spending the model discovery deadline on keyring-backed decryption.
GitOrigin-RevId: 2862850215abce478136137b9b68a37f3caaeed4
## What changed
- Share the harness runtime identity with analytics delivery and turn-cost queries, and resolve request authentication together with its account-bound transport policy.
- Add runtime authentication to ChatGPT request helpers and `codex cloud`, including environment discovery. Resolve environment credentials for each request and honor CLI configuration overrides when loading cloud authentication.
- Preserve custom-backend authentication, validate runtime destinations, and keep cloud requests from following redirects.
- Forward only organization and project selectors from model-provider headers to API-key analytics requests.
## Testing
Add regression coverage for runtime request signing, credential refresh, account and resource selection, redirect credential handling, custom destinations, and cloud credential-store overrides.

## What changed
Update `seed_gateway_auth` to seed either the keyring or file credential store according to the provider's configuration, using `GatewayAuthManager::credential_id()` to identify credentials.
Use file storage in the gateway model-cache reuse and login-required invalidation tests to keep keyring latency outside the behavior under test.
GitOrigin-RevId: 23b4f31b6d9f9561638267723582af73eabefcfc
## What changed
Allow gateway OAuth configuration to select `credentials_store = "file"` to persist credentials in plaintext at `$CODEX_HOME/secrets/gateway_oauth.json`. Keep `keyring` as the default.
Read, update, and delete file-backed credentials by credential ID, using atomic writes and the existing cross-process lock. Preserve the serialized provider identity when using the default store.
## Testing
Add an app-server test that completes gateway OAuth login with file storage, verifies Unix file permissions are `0600`, and checks that login remains successful after a server restart.

## Why
Model catalog refreshes need to use the same registered actor and credential owner as model requests when runtime authentication is enabled.
## What changed
- Add `ProviderAuthContext` to carry credentials and optional runtime authentication into model providers and catalog clients.
- Select runtime authentication independently for inference and catalog destinations. Reject unsupported OpenAI origins while preserving provider authentication for other destinations.
- Include API organization and project selectors in runtime registration. Reuse registered runtimes across projects within an organization and replace them when the organization changes.
- Preserve transport restrictions and account bindings, and strip sensitive headers on cross-origin redirects.
- Apply the catalog timeout to authentication and fetching while allowing credential refresh and registration to finish safely.
## Testing
Add coverage for runtime-authenticated catalogs, provider isolation, resource selection, gateway authentication, cross-origin redirects, and timeout recovery that preserves registration and refreshed tokens.

## What changed
Remove `AuthProvider::resolve_auth_headers` and use `apply_auth_headers` as the async interface for header-only authentication. Migrate providers, callers, and existing tests to the shared interface, passing an empty `HeaderMap` when only authentication headers are needed.
Document that providers may refresh credentials asynchronously and that callers must use the returned header map so providers can remove superseded credentials.

## 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.

## Why
A failed provider catalog refresh could discard model metadata and disable tool search on subsequent turns, even after a successful discovery.
## What changed
Keep the last successful catalog, ETag, and original freshness when refreshes fail without an access rejection. Continue invalidating cached catalogs for HTTP `401`/`403`, rejected refresh tokens, and gateway credentials that require login. Distinguish `GatewayLoginRequired` from login in progress so only the former invalidates the catalog.
Successful empty responses remain authoritative, and cached catalogs remain scoped to the provider and authentication identity.
## Testing
Add regression coverage for catalog preservation across refresh errors and restarts, access rejection invalidation, identity isolation, and tool search and instruction stability on the next turn after a failed refresh.
GitOrigin-RevId: 9dd7c73ac2cc1fd49664efd93b839baa94e05c49
## Why
Synchronous auth header construction could silently return no credentials when managed authentication became unavailable. Callers need an error to avoid sending requests with missing or partial authentication.
## What changed
- Make `AuthProvider::add_auth_headers`, `to_auth_headers`, and auth header telemetry fallible, and propagate failures through request and WebSocket setup.
- Return a transient error when managed authentication is unavailable, and preserve network policy denials through auth error conversion.
- Retry transient MCP authentication errors while treating build errors and policy denials as terminal.
- Cancel local MCP event streams before resolving authentication so cleanup still works when credentials become unavailable.
## Testing
Add regression coverage for rejected partial authentication, async header resolution, terminal auth errors without sending requests, managed account changes, MCP retry classification, and local stream cancellation after authentication becomes unavailable.
GitOrigin-RevId: 39d981e232cba1e302de502a2fa6239101114ed1
## What changed
- Add `GatewayLoginControl` so hosts can require caller-initiated browser authorization while retaining automatic login by default.
- Expose passive readiness checks, scoped status subscriptions, and cancellable browser login that reports success after credentials are persisted.
- Return non-retryable request errors for `LoginRequired` and `LoginInProgress`, while preserving retries for transient authentication failures.
- Keep rejected credentials unready until replaced, and prevent slow readiness reads from blocking cached requests or overwriting newer credentials.
## Testing
Add coverage for login cancellation, status notifications, external credential recovery, concurrent credential I/O, legacy automatic login, and request retry behavior.
GitOrigin-RevId: e236d203998ceb6eeaca9704cc05d20ad45f2931
## Why
Providers need to serve Codex model metadata independently of their inference endpoint. A custom inference `base_url` alone should not opt API-key sessions into remote catalog discovery.
## What changed
- Add `model_catalog_url` to provider configuration and thread-config serialization. Fetch the full catalog URL with provider authentication, headers, query parameters, and `client_version`, while preserving inference routing.
- Require an explicit catalog URL for API-key discovery with a custom base URL. Keep default OpenAI discovery on the Codex backend, and apply `api_key_model_discovery` gating to provider API keys and cached catalogs.
- Include the catalog URL in cache identity so different catalogs do not share cached metadata.
- Limit explicitly configured catalog responses to 1 MiB, reject redirects, and suppress URL and response diagnostics that could expose credentials.
## Testing
Add coverage for catalog configuration round-trips, query encoding, authentication and header reuse, cache identity and discovery gating, oversized responses, and redirect rejection without credential forwarding. Add an integration test verifying that catalog model metadata and instructions reach conversation requests.
GitOrigin-RevId: 7f6ac5eec257278685e1867a6bcebae6514a365a
## Why
Providers configured with `gateway_oauth` need gateway credentials alongside primary authentication for inference and model discovery.
## What changed
- Attach gateway tokens through the configured header or cookie while preserving primary authentication, including WebSocket handshake headers.
- Share gateway credential managers across matching provider instances and model discovery so they observe refreshed tokens.
- Reject authentication on gateway setup or token failures, invalid token values, and conflicting auth headers. Mark gateway headers sensitive and avoid exposing issuer error details.
- Include gateway OAuth configuration in model catalog cache identity to prevent reuse across different gateway configurations.
## Testing
Add provider and core integration tests covering combined credentials, header and cookie delivery, token refresh, shared credential state, cache isolation, and request blocking on gateway token or HTTP client initialization failures.
