@@ -140,6 +140,7 @@ Docs: https://docs.openclaw.ai
 - xAI/Responses: normalize image-bearing tool results for xAI responses payloads, including OpenResponses-style `input_image.source` parts, so image tool replays no longer 422 on the follow-up turn. (#58017) Thanks @neeravmakwana.
 - Cron/isolated sessions: carry the full live-session provider, model, and auth-profile selection across retry restarts so cron jobs with model overrides no longer fail or loop on mid-run model-switch requests. (#57972) Thanks @issaba1.
 - Matrix/direct rooms: stop trusting remote `is_direct`, honor explicit local `is_direct: false` for discovered DM candidates, and avoid extra member-state lookups for shared rooms so DM routing and repair stay aligned. (#57124) Thanks @w-sss.
+- Matrix/DM threads: only promote fresh invite rooms when Matrix marks the invite as direct, keep failed local DM repairs stable across later replies, and keep thread-isolated Matrix sessions reporting the correct route policy.
 - Agents/sandbox: make remote FS bridge reads pin the parent path and open the file atomically in the helper so read access cannot race path resolution. Thanks @AntAISecurityLab and @vincentkoc.
 - Tools/web_fetch: add an explicit trusted env-proxy path for proxy-only installs while keeping strict SSRF fetches on the pinned direct path, so trusted proxy routing does not weaken strict destination binding. (#50650) Thanks @kkav004.
 - Exec/env: block Python package index override variables from request-scoped host exec environment sanitization so package fetches cannot be redirected through a caller-supplied index. Thanks @nexrin and @vincentkoc.
