// from the top of handleChatCore (chatCore god-file decomposition, #3501). Locks the endpointPath
|

// construction, the /responses detection, the nativeCodexPassthrough + isDroidCLI + copilot wiring,
|
|
// and the clientResponseFormat downgrade (OpenAI Responses shape off a non-/responses, non-Droid
|
|
// endpoint collapses to plain OpenAI).
