@@ -26,6 +26,7 @@ Docs: https://docs.openclaw.ai
 - Update: carry plugin-validation bypasses into config mutation pre-write reads, so package update doctor repairs can finish while externalized plugin schemas are converging.
 - Agents/subagents: warn and continue completion announce cleanup when lifecycle cleanup fails, preventing ended subagent runs from becoming silent ghosts. Fixes #82306. Thanks @SebTardif.
 - Telegram: let authorized text `/stop` commands use the fast-abort path before queued agent work, so active turns stop immediately instead of processing the abort after the turn finishes; foreign-bot `/stop@otherbot` mentions now stay on the regular topic lane instead of being routed into our control lane. Fixes #82162. Thanks @civiltox.
+- Task persistence: drop malformed array/scalar requester-origin JSON from task and task-flow SQLite sidecars instead of restoring it as delivery metadata.
 - Agents/timeouts: clarify model idle-timeout errors and docs so provider `timeoutSeconds` is shown as bounded by the whole agent/run timeout ceiling.
 - Release tooling: align the published launcher Node floor, `npm start`, package script checks, sharded lint locking, Vitest root project coverage, and plugin-SDK declaration build cache metadata so release/package validation does not silently skip or ship stale surfaces.
 - Cron/agents: honor configured subagent model fallbacks for isolated scheduled runs and forward that fallback policy into embedded agent timeout failover. Fixes #74985. Thanks @chrisgwynne.
