## What changed
- Rename ChatGPT-specific bundle loaders to `chatgpt_config_bundle_loader*` and use managed-config terminology for shared loader plumbing.
- Pass `Config` directly when updating the app-server's managed configuration loader.
- Share configuration loading, logging setup, and result handling between browser and device-code login.
- Expose the CLI cloud-config helpers and `provider_uses_first_party_auth_path` through their library APIs.
## Testing
Extend CLI login coverage to verify that `forced_login_method="api"` rejects both `login` and `login --device-auth` while preserving saved API-key credentials.

## Why
Remote registry requests need to recover when credentials are rejected or rotated while `exec-server` is running. Concurrent requests should reuse refreshed credentials rather than refresh the replacement token again.
## What changed
- Add an `AuthProvider` recovery hook and retry registry registration, connection, and harness-key validation once after a `401` when the provider supplies replacement credentials.
- Use live ChatGPT authentication for remote `exec-server` and guard proactive and unauthorized refreshes so concurrent callers share the completed refresh.
- Allow executor credentials to retry when the parent has already supplied a valid replacement.
- Keep connection authentication, refresh, and retry within the original connection deadline.
## Testing
Add coverage for concurrent refreshes, stored and parent-supplied credential rotation, refresh failures, retry limits, and connection deadlines, plus a CLI integration test for refresh and credential reload in a running executor.

## What changed
- Add `--executor-credential-stdin` to read newline-delimited JSON credentials bound to the configured environment. Require an initial credential within 30 seconds and accept subsequent rotations.
- Reject expired credentials on each request, and stop the executor on invalid input or stdin closure. Limit credential frames to 16 KiB.
- Use scoped bearer authentication for registry requests without account credential fallback or WebSocket authentication headers. Skip workload identity loading and configured telemetry exporters in this mode.
## Testing
Add unit and integration coverage for rotation, expiry, malformed frames, environment mismatches, stdin closure, registry-only authentication, credential redaction, and telemetry exporter isolation.

## Why
Executor config reads omitted the startup `features.prefer_mxc` override, so clients could not see the CLI sandbox preference.
## What changed
- Include the explicit CLI `features.prefer_mxc` value in `environmentConfig/read` as a `session-flags` layer, above project config and below legacy managed file and MDM config.
- Retain only this preference from startup overrides.
- Expose `windows_mxc_allowed_by_config` to share MXC eligibility checks after callers resolve the active permission profile.
## Testing
Add CLI and remote executor coverage for preference propagation and filtering, plus a unit test verifying that both legacy managed config sources retain precedence.

## Why
Private IP destinations always bypassed inherited upstream proxies, preventing their use for private networks reachable through an upstream VPN proxy.
## What changed
- Add `codex exec-server --proxy-private-ips-via-upstream`, also configurable with `CODEX_EXEC_SERVER_PROXY_PRIVATE_IPS_VIA_UPSTREAM=true`. The setting defaults to disabled.
- Allow permitted RFC 1918, carrier-grade NAT, and IPv6 unique-local destinations to use an applicable upstream proxy. Loopback and link-local destinations retain direct routing, and destination access policy still applies.
- Keep connections direct when no valid upstream proxy applies or `allow_upstream_proxy=false`. Errors after selecting an upstream proxy do not trigger a direct retry.
- Rename `ExecServerRuntimePaths` to `ExecServerRuntimeOptions` and carry the routing setting from executor startup into the managed network proxy.
## Testing
Add routing coverage for private address ranges, special-use addresses, and public targets with the option enabled and disabled. Verify that HTTP and CONNECT requests still enforce destination allowlists and denylists, and update the CLI help snapshot.

## Why
When a container denies fresh `/proc` mounts, the existing sandbox fallback retains the caller's `/proc` while creating a new PID namespace. Process IDs inside the sandbox can then differ from those exposed by `/proc`, breaking process lookups.
## What changed
- Add `codex exec-server --linux-sandbox-pid-namespace=inherit` to reuse the caller's PID namespace and `/proc` for both process and filesystem helpers. Repository config and command environment variables cannot enable it.
- Keep `isolate` as the default, preserving the existing mount fallback and compatibility with older helpers. Inheritance requires an updated helper and omits `--unshare-pid` and `--as-pid-1`.
- Preserve other sandbox restrictions. With `:minimal`, bind the inherited `/proc` read-only with its container masks and apply explicit filesystem denials afterward.
Inheritance is intended for dedicated environments: it allows sandboxed commands to signal other same-UID processes, including the executor.
## Testing
Add unit and integration coverage for namespace flags, denied proc mounts, consistent process IDs, retained sandbox restrictions, and startup-only selection across process and filesystem helpers.

## What changed
Expose the shared `--ws-auth` options on `codex exec-server` for direct WebSocket listeners. Support capability tokens configured by token file or SHA-256 digest, and signed JWT bearer tokens. Validate `Authorization: Bearer TOKEN` before each WebSocket upgrade, rejecting missing or invalid credentials with HTTP 401 when authentication is enabled.
Reject listener authentication with stdio, `--remote`, or `forward`. Document the options and connection-time authentication behavior.
## Testing
Add CLI integration tests for all three credential configurations, unauthorized upgrade rejection, authenticated RPC initialization and reconnects, invalid configuration, and incompatible transports.

## Why
AWS credential discovery, analytics, and telemetry used clients that did not share the application's network policy. These requests need to honor destination restrictions and permission revocation.
## What changed
- Route AWS credential and region HTTP requests through the shared HTTP client, and check the signing destination before loading credentials. Skip discovery for static access keys with an explicit region.
- Apply account-scoped policy to Bedrock authentication. Require unrestricted policy for credential exporters and reauthentication commands, and cancel active work when permission is revoked. Document that AWS profile `credential_process` network traffic remains outside the application's HTTP policy.
- Send analytics through the authenticated account's HTTP client factory.
- Guard OTLP log, trace, and metric exports with revocable permits, disable them under destination restrictions, and make managed HTTP exports cancellable. Suppress global Statsig settings while managed policy is active.
## Testing
Add coverage for metadata credential request cancellation, allowed and denied SigV4 destinations, AWS credential precedence and endpoint configuration, and blocked credential exporter recovery. Update telemetry tests for account transitions and managed-policy Statsig suppression.

## What changed
Move `codex exec-server` argument definitions, transport validation, configuration loading, authentication, and shutdown orchestration from `codex-rs/cli/src/main.rs` into `codex-rs/cli/src/exec_server_command.rs`.
Expose startup through `ExecServerCommand::run`, merge the root `--strict-config` flag into the command before dispatch, and update existing argument tests to use the new entry point.
