## 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.

ThreadManager Sample
Small one-shot binary that starts a Codex thread with ThreadManager from
codex-core-api, submits a single user turn, and prints the final assistant
message.
Authentication uses the configured credential storage under CODEX_HOME, including
cli_auth_credentials_store, mcp_oauth_credentials_store, and
features.secret_auth_storage. Local managed authentication requirements and auth
routing settings are respected. This also applies to cargo run builds. Other
execution settings remain the sample's built-in configuration.
cargo run -p codex-thread-manager-sample -- "Say hello"
Use --model to override the configured default model:
cargo run -p codex-thread-manager-sample -- --model gpt-5.2 "Say hello"
The prompt can also be piped through stdin:
printf 'Say hello\n' | cargo run -p codex-thread-manager-sample
