@@ -112,6 +112,7 @@ Docs: https://docs.openclaw.ai
 - Gateway/HTTP: avoid loading managed outgoing-image media handlers for unrelated requests, so disabled OpenAI-compatible routes return 404 without waiting on lazy media sidecars. Thanks @vincentkoc.
 - Gateway/OpenAI-compatible: send the assistant role SSE chunk as soon as streaming chat-completion headers are accepted, so cold agent setup cannot leave `/v1/chat/completions` clients with a bodyless 200 response until their idle timeout fires.
 - Agents/media: avoid direct generated-media completion fallback while the announce-agent run is still pending, so async video and music completions do not duplicate raw media messages. (#77754)
+- WebChat/Codex media: stage Codex app-server generated local images into managed media before Gateway display, so Codex-home image paths no longer hit `LocalMediaAccessError` while keeping Codex home out of the display allowlist. Thanks @frankekn.
 - TUI/sessions: bound the session picker to recent rows and use exact lookup-style refreshes for the active session, so dusty stores no longer make TUI hydrate weeks-old transcripts before becoming responsive. Thanks @vincentkoc.
 - Doctor/gateway: report recent supervisor restart handoffs in `openclaw doctor --deep`, using the installed service environment when available so service-managed clean exits are visible in guided diagnostics. Thanks @shakkernerd.
 - Gateway/status: show recent supervisor restart handoffs in `openclaw gateway status --deep`, including JSON details, so clean service-managed restarts are reported as restart handoffs instead of opaque stopped-service diagnostics. Thanks @shakkernerd.
