Branches of a file in a live session: create, edit, review, update from
main and merge while the file is in a session. The branch stays with its
author and makes ids in their own client space far above the main file's;
merging is one synced edit and one undo step; peers' edits merge against
the branch's own base and conflicts resolve as offline; a view link still
refuses merging; a branch made outside the session that adds layers is
refused with a reason. Branch history entries for creation and updates
from main. Fuzz and junk tests extended to export settings, guides and the
live case. Docs: gap 17, collaboration parity, ROADMAP, mcp, protocol.
SaveFiles named each test's folder after the process id and the
clock in nanoseconds. The tests run in parallel and the macOS clock
counts microseconds, so two of them often got the same folder and one
failed with AlreadyExists (14 of 30 runs here). A counter now keeps
the names apart.
Save as now offers .figcraft and .fig as separate file types. A .fig
destination, chosen in the dialog or passed to file.saveAs and file.save,
writes the existing experimental .fig export of the document that is shown
and reports how much was left out. The file's own path, unsaved changes,
versions, branches and undo history are not touched, and a shown earlier
version stays shown while the copy is written or a Save as choice is
pending.
Plain Save no longer writes over a file whose saved path ends in .fig;
earlier builds could write native data under that name. It asks for a
destination instead.
