Development record

A record's file name has no cap tied to the length of its full path, so a record checked out on Windows can pass the 260-character path limit, which the product thinker reports records already do. The longest tracked path is 149 characters inside the repository; the checkout's own location comes on top, and a worktree in the machine store adds its prefix, the 40-character root commit and the worktree's name. Git for Windows will not check such a file out unless core.longpaths is set (itd-2610070544145422 is the Windows install draft).
