Controlled by server-sent capability policy.

nodes. Not yet productized into something user-accessible. (Notably,

yet.) This purely permits expanding the set of expands a node will
accept a drop from.

If DeleteFile fails on Windows due to another process (anti-virus,
probably) having our file open, instead leave a marker file that the

It used to just store received files URL-escaped on disk, but that was
a half done lazy implementation, and pushed the burden to callers to
validate and write things to disk in an unescaped way.
Instead, do all the validation in the receive handler and only
accept filenames that are UTF-8 and in the intersection of valid
names that all platforms support.
