- support sub-api/openai-responses through the public Responses endpoint - preserve explicit Authorization and support header-only authentication - retain Codex JWT requirements and native compaction failure fallback - restore SubAPI checkpoints and preserve portable model-switching summaries - add provider, authentication and checkpoint lifecycle regression tests - document compatibility requirements and the Sub2API protocol reference
