 - Image sanitization only.
 - Drop orphaned reasoning signatures (standalone reasoning items without a following content block) for OpenAI Responses/Codex transcripts, and drop replayable OpenAI reasoning after a model route switch.
 - Preserve replayable OpenAI Responses reasoning item payloads, including encrypted empty-summary items, so manual/WebSocket replay keeps required `rs_*` state paired with assistant output items.
+- Native ChatGPT Codex Responses follows Codex wire parity by replaying prior Responses reasoning/message/function payloads without prior item IDs while preserving session `prompt_cache_key`.
 - No tool call id sanitization.
 - Tool result pairing repair may move real matched outputs and synthesize Codex-style `aborted` outputs for missing tool calls.
 - No turn validation or reordering.
