 ### Fixes
 
+- Agents/OpenAI: surface selected-model capacity failures with a model-switch hint instead of the generic empty-response error. Thanks @vincentkoc.
 - Providers/OpenAI: stop advertising the removed `gpt-5.3-codex-spark` Codex model through fallback catalogs, and suppress stale rows with a GPT-5.5 recovery hint.
 - Plugins/QR: replace legacy `qrcode-terminal` QR rendering with bounded `qrcode-tui` helpers for plugin login/setup flows. (#65969) Thanks @vincentkoc.
 - ACPX/Codex: stop the embedded Codex ACP auth bridge from falling back to raw `~/.codex` file copies; ACPX now only uses OpenClaw's canonical Codex OAuth bridge.
