2.1.1
The Windows runner asset drops from 564MB to 134MB. That file is what a user without Node installed downloads in order to spawn a bot, which is why this is a release rather than something held for later.
Asking for a Minecraft version outside the supported range now fails saying it was never included, instead of behaving as though the game had no blocks.
Nothing breaks against 2.1.0.
Fixed
The docs stated a permission policy that Paper changes between versions. A non-op is refused /list on Paper 1.21.8 and runs it on Paper 1.21.1, but the tool description, the usage docs and the verification skill all told you a non-op would be refused. What command_exec reports was never wrong — it asks the server rather than assuming — only the text around it.
Verified at both ends of the supported range: all 21 compatibility checks pass on Paper 1.21.8 and on 1.21.1, driven by the 134MB executable.
