Windows (WSL2) Host: the page W2 owes, and the checklist that settles it New page: setup inside the distribution, the one hard rule about where the jam's state directory may live (not a Windows drive — DrvFs reports 0777 and chmod there does nothing), C:\ and \\wsl$ paths at /send, /paste through interop, and who can actually reach a jam inside a NAT'd VM (localhost from Windows on the same PC; mirrored networking, a portproxy, or --tunnel for anybody else). It opens by saying that nobody working on claude-jam has a Windows machine and that the WSL-specific behaviour has never been run on a real install, and it ends in a nine-step checklist where each step is a command and an expected observation — starting with `node scripts/check-wsl.mjs`, which answers most of it and needs no npm install. Linked from Home and Install; Files-and-Export corrects "/paste is macOS only" (it is macOS, Windows and WSL2 now) and gains the /send path rule; Troubleshooting gains the five failures a WSL host will actually hit.
