CHANGELOG.md

@@ -44,6 +44,7 @@ Docs: https://docs.openclaw.ai
 - Docs/Mintlify: fix MDX marker syntax on Perplexity, Model Providers, Moonshot, and exec approvals pages so local docs preview no longer breaks rendering or leaves stale pages unpublished. (#46695) Thanks @velvet-shark.
 - Email/webhook wrapping: sanitize sender and subject metadata before external-content wrapping so metadata fields cannot break the wrapper structure. Thanks @vincentkoc.
 - Node/startup: remove leftover debug `console.log("node host PATH: ...")` that printed the resolved PATH on every `openclaw node run` invocation. (#46411)
+- ACP/approvals: use canonical tool identity for prompting decisions and fail closed when conflicting tool identity hints are present. Thanks @vincentkoc.
 - Telegram/message send: forward `--force-document` through the `sendPayload` path as well as `sendMedia`, so Telegram payload sends with `channelData` keep uploading images as documents instead of silently falling back to compressed photo sends. (#47119) Thanks @thepagent.
 - Telegram/message chunking: preserve spaces, paragraph separators, and word boundaries when HTML overflow rechunking splits formatted replies. (#47274)
