## What changed
Add `modelProvider/config/write` to create custom gateways and patch existing custom gateway, Bedrock, and GCP settings. Return the saved provider using the same safe summary as `modelProvider/list`.
Omitted fields retain their values; explicit `null` clears nullable user overrides. Apply patches through the shared configuration queue with last-write-wins semantics, enforce field editability and validation, and preserve unexposed authentication settings.
Saving leaves provider selection and authentication unchanged. Saving the provider used by `model/list` invalidates its catalog for the next access. Include documentation and generated JSON, TypeScript, and Python protocol types.
## Testing
Add coverage for gateway creation and ID allocation, patch and null semantics, configuration policy enforcement, authentication preservation, and catalog refresh after active-provider edits. Extend Python protocol tests to verify wire round trips and reject mismatched provider IDs or fields.
GitOrigin-RevId: 850fe2c48ef5274944400efb5a859d720179c923
## What changed
- Add `modelProvider/list` to return OpenAI and explicitly configured providers, provider-specific settings, and the selected default provider.
- Report `canEdit` and `canChangeDefault` based on configuration requirements, layer precedence, and whether user configuration is enabled.
- Describe gateway authentication without resolving credentials, and omit endpoint URLs that are unsuitable for display.
- Document the API and update generated JSON schemas, TypeScript types, and Python models.
## Testing
Add app-server tests for provider discovery, authentication modes, unsafe URL suppression, and configuration editability, plus a Python wire-format round-trip test.
GitOrigin-RevId: 8ba26637cd6bdd075e0e815e88aeeb04c53a2364
## What changed
Add `otel.log_sse_deltas`, enabled by default. Setting it to `false` suppresses successful SSE event logs whose kind ends in `.delta` while preserving errors, completion events, and metrics.
Apply the setting to session and memory telemetry, support managed requirements, and expose it in the app-server configuration requirements API and generated schemas and bindings.
## Testing
Add coverage for delta log suppression with errors, completion logs, event counts, and duration metrics preserved. Extend configuration and app-server tests to cover defaults, overrides, and managed requirements.
GitOrigin-RevId: 751c7f357c41f51848b025c838246a733eb92e2f
## Why
Managed OpenTelemetry requirements could not specify span attributes or tracestate metadata.
## What changed
- Accept `otel.span_attributes` and `otel.tracestate` in requirements, merge them by attribute or member field, and expose them through app-server configuration and requirements reads.
- Protect required entries and their ancestors from configuration writes while preserving unmanaged sibling values and their origins. For example, requiring `otel.tracestate.vendor.tenant` leaves `vendor.region` writable. Empty metadata maps impose no requirements.
- Select Rustls when configuring an OTLP HTTP client certificate and private key so PEM client identities are accepted.
## Testing
Add coverage for metadata precedence, effective configuration, field-level write protection, and preservation of unmanaged values. Add blocking and asynchronous HTTP client construction tests using generated PEM certificates and keys.
GitOrigin-RevId: ada6000cc5e575b9a33451ec4aa58b6686dc20f7
## Why
OTEL exporter headers can contain credentials. Configuration responses exposed these values in effective config, source layers, managed requirements, and write-override metadata.
## What changed
Replace header values with `[redacted]` across these responses for log, trace, and metrics exporters while preserving header names. Keep the original values available to runtime exporters, and redact them in debug output. Update protocol schemas and generated client documentation to describe the redacted values.
## Testing
Add coverage for effective config and source-layer redaction, managed requirements, and single and batch write-override metadata, including header names containing dots. Extend telemetry integration coverage to verify that runtime requests still carry the configured header value.
GitOrigin-RevId: ad24e8b91e615bd36c03c4c0ca205ac64bbd8cbf
## What changed
- Allow `requirements.toml` to manage OpenTelemetry logging flags, tool-result byte limits, environment, and log, trace, and metrics exporters.
- Apply higher-priority managed values over user configuration, replacing exporters atomically and warning when configured values conflict. Preserve unmanaged settings, including `span_attributes` and `tracestate`.
- Expose managed `otel` settings through `configRequirements/read`, apply them in `config/read` without ordinary field origins, and reject configuration writes that overlap managed fields.
- Distinguish omitted tool-result limits from explicit values while preserving the runtime default.
## Testing
Add coverage for requirement precedence, relative TLS paths, override warnings, managed write protection, effective configuration reads, and exporter serialization through the app-server API.
GitOrigin-RevId: 6a3343563bd3acb53a366ea6723684e3d0a4a01d
## What changed
- Add `account/gcp/setup` to configure the built-in Vertex AI provider with a project, optional location (defaulting to `global`), and optional credential file. Omitting the file clears the active user override and uses Application Default Credentials.
- Validate configuration and obtain an access token before saving, return structured credential failure reasons, and reload the model catalog on the next `model/list` request.
- Share configuration previews and version-checked writes with Bedrock setup to reject conflicting settings and concurrent configuration changes.
## Testing
Add tests for credential selection and ADC fallback, catalog refresh, invalid credentials, policy and endpoint conflicts, cancellation when network permission is revoked, and configuration version conflicts.
GitOrigin-RevId: 6f411a85893f8da49581427451e0180529955b16
## What changed
- Add `application.storage.default_project_parent` and `application.storage.projectless_workspace_root` requirements for new Desktop workspaces. Require absolute paths and reject unknown storage keys.
- Apply managed paths to `desktop.defaultProjectParent` and `desktop.projectlessWorkspaceRoot`, overriding local preferences and rejecting writes to managed settings or their containing table while preserving unrelated Desktop settings.
- Expose storage requirements through `config/requirements/read` and update generated JSON schemas, TypeScript types, and Python models.
## Testing
Add coverage for storage validation, per-setting layer precedence, config overrides, write protection, and requirements API responses. Adjust daemon shutdown test deadlines and TUI test synchronization, paste handling, and future allocation.
GitOrigin-RevId: 44b93fe69e6a471c3f485cbf5f9c9ebd34ac3234
## What changed
- Use the standard shell executor and remove the zsh fork escalation runtime, `codex-execve-wrapper`, and `shell-escalation` crate.
- Ignore `shell_zsh_fork` and `unified_exec_zsh_fork`, emit migration notices for legacy configuration, and warn when ignoring managed requirements for these flags.
- Keep the active session's `apply_patch` alias directory readable under restricted filesystem permissions.
## Testing
Add coverage for legacy configuration startup and shell execution, migration notice rendering, active alias directory selection, and nested `apply_patch` execution while other files in `CODEX_HOME` remain unreadable.
GitOrigin-RevId: 43af461fea32b4980550ee7237effd2bc0646ed8
## Why
Reloads can reject a valid thread configuration when the host configuration references a missing model provider that thread overrides replace. Concurrent cloud refreshes can also leave older policy snapshots or staged cache writes eligible for publication.
## What changed
- Compose preserved session layers before materializing refreshed configuration, retaining source-aware validation errors.
- Carry cloud policy revision bindings through config loading and role overrides. Reject stale MCP refreshes and disable enterprise MCP authorization when the policy is suspended. Retire the old policy when replacing or clearing its loader.
- Stage cloud cache writes in temporary files and publish them atomically only while their policy revision remains current.
- Route file reloads through the shared runtime refresh path, resolve paths relative to each config file, and preserve session settings. Restore host defaults for `secret_auth_storage` and `mcp_oauth_refresh_coordination` when explicit overrides are removed.
## Testing
Add regressions for thread-provided model providers, managed plugin and feature requirement refreshes, stale and suspended policy snapshots, superseded and retired cache writes, and file reloads preserving runtime settings and restoring feature defaults.
GitOrigin-RevId: 3280a2445eeb7074a142f720690bb0e4f01d174b
## What changed
- Load `application.network` requirements at startup and explicit config/account reloads, applying local policy before authentication and cloud configuration bootstrap.
- Block traffic when policy loading fails, cancel requests that a new policy no longer permits, and reject configuration loads based on superseded policy snapshots. Local requirements edits take effect on the next explicit reload or restart.
- Bind authenticated clients to the current account and revoke them when account ownership changes. Carry policy enforcement through backend requests, realtime connections, workload identity exchanges, and code-mode gRPC streams while preserving gRPC trailers.
- Treat denied credential refreshes as policy errors without retrying them or invalidating stored credentials.
## Testing
Add regression coverage for startup restrictions, reload ordering, cancellation after restrictive or malformed requirements edits, account revocation, gRPC destination denial, workload identity cancellation, and credential preservation after denied OAuth refresh.
GitOrigin-RevId: 0cb4c720a906397e9df06675f01ecf60d741101f
## Why
Login and enterprise configuration bootstrap can fail when their endpoints are reachable only through the system proxy, before cloud configuration can enable `respect_system_proxy`.
## What changed
- Enable `features.system_proxy_fallback` by default, honor managed feature requirements, and prevent project configuration from changing it.
- Retry account discovery and cloud configuration GETs through the system proxy after connection failures or timeouts, bounding the initial request and body read to five seconds.
- Retry OAuth authorization-code exchange only on connection failures before any redirect, with a ten-second connection timeout. Reuse the successful client for the subsequent API-key exchange to avoid changing routes.
- Increase workspace discovery and cloud configuration timeouts to 15 and 20 seconds, respectively, to accommodate fallback.
## Testing
Add coverage for proxy-only browser login through the first completed turn, including cloud configuration enabling `respect_system_proxy` without a restart. Cover stalled GET bodies, preserved request headers, disabled fallback, managed requirements, and project configuration restrictions. Verify that OAuth HTTP errors, redirects followed by connection failures, and failures after sending the POST do not trigger proxy retries, while successful redirects remain supported.
GitOrigin-RevId: 854eeeac186bb4865218ce645019c1e4bff85425
## What changed
- Remove the private-desktop opt-out from elevated and unelevated Windows sandbox launches.
- Remove `windows.sandbox_private_desktop` and its managed requirement and API fields. Warn users to remove the obsolete setting.
- Require a private desktop name when launching through the Windows sandbox wrapper and command runner.
## Testing
Add coverage for the obsolete-setting migration warning and update wrapper tests to verify a live private desktop is passed and a missing desktop name is rejected.
GitOrigin-RevId: c7135f8d211aac8d812180691c2c1e433d77cde4
## Why
Server-level tool exposure settings apply to every connector on the apps server. Individual connectors need a way to opt out of deferred discovery without changing exposure for other apps.
## What changed
Add `apps.<connector_id>.omit_tools_from` with support for `code_mode`, `deferred`, and `direct`. Combine connector omissions with server omissions so app settings preserve server restrictions.
For example, `omit_tools_from = ["deferred"]` makes a connector's tools available without tool search, through direct calls or Code Mode as permitted by the active tool mode and remaining restrictions.
Expose the setting in the app-server protocol, JSON schemas, and generated TypeScript and Python types.
## Testing
Add integration coverage for connector-specific exposure and MCP dispatch across tool modes, server restrictions, and direct-only namespaces. Extend config tests to cover populated, absent, and empty omission lists, and add a Code Mode request-history snapshot.
GitOrigin-RevId: cc99ab290c8a878d06d8d7ccf2d1dbd7c46bfa8a
## Why
Permission profile changes reloaded configuration without the thread's session overrides, so profiles defined at thread start could be unavailable to `thread/settings/update`.
## What changed
Reload permission configuration with the thread's merged, enabled `SessionFlags` layers, the effective working directory, and the requested profile. Preserve sandbox executable paths through `ConfigManager`.
## Testing
Add regression coverage for switching away from and back to session-defined and disk-defined profiles, including top-level profile selection. Add a config manager test for merging session layers, excluding disabled layers, and retaining filesystem access to the exec wrapper directory.
GitOrigin-RevId: b0271e28a90cd55d3faf5fdf5f044d768395b0b6
## What changed
- Add an optional `WorkspaceRoutingResolver` to `AuthManager` and pass session configuration into routing lookups. Callers without a resolver retain existing routing behavior.
- Apply resolved backend origins and account routing overrides to eligible ChatGPT Responses HTTP requests and WebSocket handshakes. Preserve endpoint paths, validate routing values, and reject HTTP redirects for routed requests, including `NO_CONSTRAINT` routes.
- Key cached WebSocket connections by destination, routing header, and auth revision. Rebuild request setup after credential refreshes and reject account changes during setup or routing discovery.
- Serialize routing lookups per session and retain whether the session has previously been routed.
## Testing
Add tests for path preservation, provider exclusions, concurrent routing lookups, unavailable resolvers, workspace mismatches, redirect rejection, and credential refresh or account changes during request setup.
GitOrigin-RevId: 2b6609019e84a315745c94858955f3f16426fe7f
## What changed
- Accept and ignore `features.personality` in user configuration, profiles, and managed requirements.
- Remove feature gating from `personality = "none"`, which strips the literal `# Personality` section when preparing model catalog instructions. Preserve explicit base instructions and existing thread instructions.
- Document deprecated personality fields in configuration, app-server schemas, and the Python SDK: `friendly` and `pragmatic` no longer select a style, and `supportsPersonality` is always `false`.
## Testing
Add regression coverage for ignored legacy flag values and managed requirements, personality opt-out behavior with the flag absent or set to either value, role overrides, and preservation of explicit base instructions, including empty strings.
GitOrigin-RevId: 4e12c66b42bfc59d6f151a5b3c28fadc6654ae99
## Why
Configuration requirements did not report which login methods the running app server permits after applying managed policy, forced login settings, and workspace restrictions.
## What changed
- Add `allowedLoginMethods` to `configRequirements/read`, using the running authentication manager's effective policy rather than newly read authentication settings.
- Return requirements when login methods are restricted even without managed requirements, while preserving `requirements: null` for the unrestricted default.
- Update protocol schemas and generated TypeScript and Python types. An empty list permits no login method; older servers may omit the field.
## Testing
Add coverage for managed and forced login restrictions, workspace intersections, policy reporting after requirements files change, invalid login methods, and API-only Amazon Bedrock without ChatGPT requests. Extend tests for conflicting authentication requirements and cloud policy precedence.
GitOrigin-RevId: 56c0767a74143e793aac2ac165d0cbe98a09469b
## What changed
- Let higher-priority providers in `features.network_proxy.credentials` displace lower-priority providers with overlapping `env` sources, including in profiles. Preserve inherited settings when providers swap sources, and compare environment names case-insensitively on Windows.
- Preserve provider definitions across ordered batch remaps and persist displaced-provider removals without overwriting unrelated sibling updates.
- Validate remapped providers using the credential broker's compilation rules before persisting writes, while allowing incomplete drafts and explicit deletions.
- Omit displaced providers from config origins and report writes overridden by another provider's source ownership.
- Build trusted credential-broker configuration before merging managed layers for project discovery, preserving remapped providers' environment protections.
## Testing
Add unit and config RPC regression tests for source precedence, source swaps, ordered edits, concurrent sibling updates, atomic rejection of invalid remaps, persistence, and override reporting. Add a macOS managed-config regression test for remapped provider bindings during project discovery.
GitOrigin-RevId: b7d402727acf4e5b0f25946db1cf18811f5e2679
## Why
Credential brokerage must retain trusted destination hints even when shell environment policy hides them from child processes. Snapshot replay also needs to preserve credential aliases when tokens are short or captured dummy values change.
## What changed
- Add `features.network_proxy.credentials` and preserve provider settings when toggling the proxy. Prevent project configuration from overriding providers or their credential and destination environment variables.
- Use provider metadata throughout snapshot capture and replay, and pass hidden destination context to the broker without exposing it in the child environment.
- Rewrite aliases containing short credentials or previously captured dummies, respecting environment filters and explicit overrides.
- Preserve case-distinct `shell_environment_policy.set` keys so Windows credential ambiguity checks survive configuration merging and permission profile changes.
- Restore independent MITM settings when credential brokerage is disabled.
## Testing
Add regression coverage for custom providers, hidden destination hints, Bash and Zsh alias replay, configuration edits and merging, Windows ambiguity handling, and credential protection during approved execution.
GitOrigin-RevId: b2bd935d2d8555be56baf8feb1a8e5b3a0c666bc
## What changed
- Add `apps.<app_id>.links.<link_id>` configuration for overriding
`approvals_reviewer` and `default_tools_approval_mode` per connected account.
- Expose link settings through the app-server protocol and generated JSON and
TypeScript schemas.
## Testing
- Extend `config/read` coverage for populated, empty, and absent `links`
sections.
GitOrigin-RevId: 43004d2722439060fdadc5e5cd9ed3108774ecaf
## 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
- Add `features.network_proxy.credential_broker` and preserve structured network proxy settings when toggling the feature through config APIs.
- Protect broker enablement and provider context variables from project config, while carrying trusted context into filtered shell environments.
- Propagate brokered credentials through shell snapshots and restore real credentials for unsandboxed escalated commands.
- Normalize broker context environment keys case-insensitively on Windows and avoid conflicting remote managed-network enforcement when no proxy launch configuration is available.
## Testing
- Cover config layering, editing, project sanitization, Windows environment handling, shell snapshots, escalated execution, and end-to-end GitHub credential brokering in the zsh-fork runtime.
GitOrigin-RevId: 500e51e804e1988022052ccfe00b8fac5e495f4f
## What changed
- Allow `features.guardianv2` to remain a boolean toggle or specify classifier instructions, the review threshold, reasoning effort, and action and instruction token limits.
- Add transcript controls for included sources, per-entry and total token budgets, and the number of recent non-user entries.
- Validate configured ranges and relationships, expose them in the generated config schema, and apply the resolved settings throughout Guardian v2 classification and approval review.
## Testing
- Cover boolean compatibility, configuration parsing and boundaries, config-manager rejection, and the resulting classifier request and approval decision.
GitOrigin-RevId: dc018b53b782e2d6b4d6a795cca4945130a71678
## 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
- Add an embedded `defaults.toml` and always install it as the lowest-precedence configuration layer when no packaged-defaults path is supplied.
- Keep packaged defaults out of config RPC layer and origin metadata.
- Report a user setting as overridden only when the effective layer has higher precedence, so clearing a setting can fall back to its packaged default without a false override.
## Testing
- Cover loading the packaged layer when other configuration files are absent.
- Cover config RPC filtering and clearing a user value that falls back to a packaged default.
GitOrigin-RevId: c1c0e1e681e4ac1be2602550972533443c5df51b
## What changed
- Add the under-development `psp` feature and expose it in the config schema.
- Use the feature to attach the PSP cookie to first-party ChatGPT clients.
- Remove the hidden `--psp` flag and its process-scoped configuration plumbing.
- Preserve configured ChatGPT cookies when creating the PSP client used for GET and POST requests.
## Testing
- Update the config manager service test to verify that enabling `features.psp` retains the setting in the effective config and configures the expected ChatGPT cookie.
GitOrigin-RevId: 53acb5495d2ff71e4ed25f674a0cff787aea474a
## 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
## What changed
- Add a hidden global `--psp` runtime flag and propagate it through TUI, exec,
app-server, remote-control, and in-process startup paths.
- Attach the `oai-chat-psp=true` cookie to first-party ChatGPT requests when
enabled, using a cached cookie-aware client with sensitive request logging
disabled.
- Keep the routing selection out of persistent configuration layers while
preserving it across config refreshes and agent role changes.
## Testing
- Cover global flag parsing, app-server propagation, config-layer isolation,
and preservation across config rebuilds and role changes.
GitOrigin-RevId: 05cdc61ffd7162d8e48fc1e166f4732113e5a816
## Why
`features.multi_agent_v2` can be represented as either a legacy boolean toggle
or a table with an `enabled` field and nested settings. Layering or editing
configs that mix these forms could replace one form with the other and discard
the enabled state or nested settings.
## What changed
- Normalize boolean toggles to the table's `enabled` field when merging config
layers, applying CLI overrides, and editing user or profile config.
- Preserve nested multi-agent settings when toggling the feature, while keeping
ordinary replacement semantics for unrelated paths.
- Attribute normalized `enabled` values to the layer that supplied the boolean
toggle so config write results report overrides correctly.
## Testing
Added coverage for layered config, CLI overrides, config edits, app-server
writes, and origin metadata using both root and profile feature paths.
GitOrigin-RevId: 38b248c949b9ea5d6340a73d754f91c1834ac486
## What changed
- Apply managed values for `sqlite_home`, `log_dir`, `model_catalog_json`,
`check_for_update_on_startup`, `allow_login_shell`, the report-submission
opt-in, and `windows.sandbox_private_desktop` to the runtime configuration,
with source-aware warnings when they override configured values.
- Expose these values through `configRequirements/read`, return them from
`config/read`, include them in session config locks, and show their sources in
the TUI config debug view.
- Reject app-server writes that overlap an exact managed requirement with
`configRequirementReadonly` while leaving unrelated sibling keys writable.
## Testing
- Cover runtime overrides, requirement API mapping, config reads and writes,
session lock serialization, cross-platform path URIs, and debug output.
GitOrigin-RevId: d4e23b6fd7775c1a6dfe2eab313cdcee50b07081
## What changed
- Add `shell_environment_policy.filters`, mapping environment-variable patterns to `include` or `exclude`, while continuing to accept the legacy `exclude` and `include_only` arrays.
- Merge filter keys case-insensitively across config layers so higher-precedence entries can override individual patterns. Switching representations replaces the other representation instead of combining them.
- Reject mixed, duplicate, or malformed filter definitions in enabled layers, config writes, and reloads, while retaining the previous session configuration when a reload is invalid.
- Make config-manager reads and writes representation-aware and preserve existing formatting when updating individual policy values.
## Testing
Add coverage for parsing, schema constraints, layered merging, validation and diagnostics, config writes, override metadata, and invalid session reloads.
GitOrigin-RevId: e15464bca53e6e7ef31fcc97537fda60ed5d670a
## Why
Amazon Bedrock can use either a Codex-managed API key or credentials managed by
AWS, so logout must not remove or misrepresent credentials that Codex does not
control.
## What changed
- Remove the managed Bedrock key on logout and clear `model_provider` only when
its user-config value is still `amazon-bedrock`.
- Reject logout for AWS-managed Bedrock credentials without changing existing
authentication or configuration.
- Add a `test-logout` app-server test-client command that waits for the
resulting `account/updated` notification.
## Testing
Add coverage for managed and AWS-managed Bedrock logout, concurrent provider
changes, config reload failures, and conditional user-config cleanup.
GitOrigin-RevId: a003c0ec27ad7b36d499fe7b63ab4a0dd6369b4f
## Why
Config layer provenance describes how effective configuration was
assembled, so it belongs with the config loader rather than in
app-server's serialized API types.
## What changed
- Moved `ConfigLayerSource`, `ConfigLayerMetadata`, and `ConfigLayer`
ownership into `codex-config`.
- Kept app-server's wire payloads unchanged and added explicit
conversions at the app boundary.
- Removed lower-level app-server-protocol dependencies from config
consumers.
## Stack
This is PR 3 of 6, stacked on [PR
#29721](https://github.com/openai/codex/pull/29721). Review only the
delta from `codex/split-auth-domain-types`. Next: [PR
#29723](https://github.com/openai/codex/pull/29723).
## Validation
- `codex-config` coverage passed.
- App-server config-manager and config RPC coverage passed.
## Summary
- Adapts the moved `codex-cloud-config` crate from the legacy cloud
requirements endpoint to the new config bundle endpoint.
- Switches runtime consumers from `CloudRequirementsLoader` to
`CloudConfigBundleLoader` so one shared bundle supplies cloud-delivered
config and requirements.
- Removes the legacy cloud requirements domain loader path.
## Details
This intentionally keeps `codex-cloud-config` monolithic for review
lineage: the previous PR establishes the crate move, and this PR shows
the behavior change against that moved implementation. A follow-up PR
splits the module back into focused files.
The new bundle path preserves the important cloud requirements loader
semantics where intended: account-scoped signed cache, 30 minute TTL, 5
minute refresh cadence, retry/backoff, auth recovery, and fail-closed
startup loading. The cached payload changes from a single requirements
TOML string to the backend-delivered bundle, and validation rejects
malformed config or requirements fragments before cache write/use.
## Why
Legacy `[profiles.<name>]` config tables and the legacy `profile`
selector are being retired in favor of profile files selected with
`--profile <name>`. After #23886 removed the CLI-side legacy profile
plumbing, the app-server config surface still exposed those fields and
still carried conversion code for the old protocol shape.
## What changed
- Remove `profile`, `profiles`, and `ProfileV2` from the app-server
config protocol/schema output so `config/read` no longer returns legacy
profile config.
- Drop the old v1 `UserSavedConfig` profile conversion path from
`config`.
- Reject new app-server config writes under `profiles.*` with the same
migration direction used for `profile`, while still allowing callers to
clear existing legacy profile tables.
- Refresh app-server config coverage and the experimental API README
example around the remaining `Config` nesting path.
## Verification
- Added config-manager coverage that `config/read` omits legacy profile
config, `profiles.*` writes are rejected, and existing legacy profile
tables can still be cleared.
- Updated the v2 config RPC test to cover the rejected `profiles.*`
batch-write path.
## Why
`--profile` now selects `<name>.config.toml`, so the legacy `profile`
selector should not be reintroduced through config write or MCP tool
paths. A matching legacy selector in base user config also needs the
same migration guard as a matching legacy `[profiles.<name>]` table so
profile loading fails with one clear migration error instead of mixing
the old and new profile models.
## What
- reject non-null app-server config writes to the top-level legacy
`profile` selector
- make `--profile <name>` reject base user config that still selects the
same legacy `profile = "<name>"` value, alongside the existing matching
legacy profile-table guard
- reject removed MCP `codex` tool fields such as `profile` by denying
unknown tool-call parameters and exposing that restriction in the
generated schema
- add regression coverage for the app-server write paths, config loader
guard, and MCP tool input/schema behavior
## Verification
- targeted regression tests cover the new app-server, config loader, and
MCP rejection paths
## Why
`--profile-v2 <name>` gives launchers and runtime entry points a named
profile config without making each profile duplicate the base user
config. The base `$CODEX_HOME/config.toml` still loads first, then
`$CODEX_HOME/<name>.config.toml` layers above it and becomes the active
writable user config for that session.
That keeps shared defaults, plugin/MCP setup, and managed/user
constraints in one place while letting a named profile override only the
pieces that need to differ.
## What Changed
- Added the shared `--profile-v2 <name>` runtime option with validated
plain names, now represented by `ProfileV2Name`.
- Extended config layer state so the base user config and selected
profile config are both `User` layers; APIs expose the active user layer
and merged effective user config.
- Threaded profile selection through runtime entry points: `codex`,
`codex exec`, `codex review`, `codex resume`, `codex fork`, and `codex
debug prompt-input`.
- Made user-facing config writes go to the selected profile file when
active, including TUI/settings persistence, app-server config writes,
and MCP/app tool approval persistence.
- Made plugin, marketplace, MCP, hooks, and config reload paths read
from the merged user config so base and profile layers both participate.
- Updated app-server config layer schemas to mark profile-backed user
layers.
## Limits
`--profile-v2` is still rejected for config-management subcommands such
as feature, MCP, and marketplace edits. Those paths remain tied to the
base `config.toml` until they have explicit profile-selection semantics.
Some adjacent background writes may still update base or global state
rather than the selected profile:
- marketplace auto-upgrade metadata
- automatic MCP dependency installs from skills
- remote plugin sync or uninstall config edits
- personality migration marker/default writes
## Verification
Added targeted coverage for profile name validation, layer
ordering/merging, selected-profile writes, app-server config writes,
session hot reload, plugin config merging, hooks/config fixture updates,
and MCP/app approval persistence.

## Why
Fixes#20145.
`config/value/write` treats a JSON `null` value as a request to clear
the config key. Clearing a key that is already absent should be
idempotent, but clearing a nested key such as `features.personality`
from an empty `config.toml` returned `configPathNotFound` because
`clear_path` treated the missing `features` parent table as an error.
That makes app-server reset flows brittle because clients have to read
first and avoid sending a clear request unless the parent path already
exists.
## What Changed
- Updated app-server config clearing so missing intermediate tables, or
non-table parents, are treated as an unchanged no-op.
- Removed the now-unreachable `MergeError::PathNotFound` path from
config write merging.
- Added a regression test covering `features.personality = null` against
an empty user config.
## Verification
- `cargo test -p codex-app-server clear_missing_nested_config_is_noop`
- `cargo test -p codex-app-server` was run; the config manager unit
suite passed, but one unrelated integration test failed because
`turn_start_emits_thread_scoped_warning_notification_for_trimmed_skills`
expected `7` trimmed skills and observed `8`.
- `just fix -p codex-app-server`
# Why
Requirements support host-specific
`remote_sandbox_config.hostname_patterns`, but config loading previously
resolved and passed the system hostname through every config-loading
path even when no requirements layer used `remote_sandbox_config`. On
machines where hostname lookup is slow, startup and app-server config
reads paid for a feature that was not active.
We only need the hostname when a requirements layer actually declares
`remote_sandbox_config`, so this moves hostname resolution to the single
requirements merge point and keeps all other config callers unaware of
hostname matching.
# What
- Removed the eager `host_name` plumbing from
`load_config_layers_state`, `load_requirements_toml`, `ConfigBuilder`,
app-server `ConfigManager`, network proxy loading, and related call
sites.
- Resolve the hostname inside
`merge_requirements_with_remote_sandbox_config` only when the incoming
requirements contain `remote_sandbox_config`.
## Why
Config loading had become split across crates: `codex-config` owned the
config types and merge logic, while `codex-core` still owned the loader
that assembled the layer stack. This change consolidates that
responsibility in `codex-config`, so the crate that defines config
behavior also owns how configs are discovered and loaded.
To make that move possible without reintroducing the old dependency
cycle, the shell-environment policy types and helpers that
`codex-exec-server` needs now live in `codex-protocol` instead of
flowing through `codex-config`.
This also makes the migrated loader tests more deterministic on machines
that already have managed or system Codex config installed by letting
tests override the system config and requirements paths instead of
reading the host's `/etc/codex`.
## What Changed
- moved the config loader implementation from `codex-core` into
`codex-config::loader` and deleted the old `core::config_loader` module
instead of leaving a compatibility shim
- moved shell-environment policy types and helpers into
`codex-protocol`, then updated `codex-exec-server` and other downstream
crates to import them from their new home
- updated downstream callers to use loader/config APIs from
`codex-config`
- added test-only loader overrides for system config and requirements
paths so loader-focused tests do not depend on host-managed config state
- cleaned up now-unused dependency entries and platform-specific cfgs
that were surfaced by post-push CI
## Testing
- `cargo test -p codex-config`
- `cargo test -p codex-core config_loader_tests::`
- `cargo test -p codex-protocol -p codex-exec-server -p
codex-cloud-requirements -p codex-rmcp-client --lib`
- `cargo test --lib -p codex-app-server-client -p codex-exec`
- `cargo test --no-run --lib -p codex-app-server`
- `cargo test -p codex-linux-sandbox --lib`
- `cargo shear`
- `just bazel-lock-check`
## Notes
- I did not chase unrelated full-suite failures outside the migrated
loader surface.
- `cargo test -p codex-core --lib` still hits unrelated proxy-sensitive
failures on this machine, and Windows CI still shows unrelated
long-running/timeouting test noise outside the loader migration itself.
