Make the retained toolbar consume retail's payload-free selection notice from canonical live state so a reentrant Auto Target replacement cannot be erased by the outer clear. Restrict automatic acquisition to the requested hostile non-player monster policy and record the intentional PK edge divergence. Co-Authored-By: Codex <codex@openai.com>
