Isolated-netns test setup (a private tap-mess-0-0 so a second MAME can run without holding the owner's tap), the one-file/one-index TFTP servers, the trace/probe run wrappers, and the two server logs quoted in FONT_STORAGE_REPORT.md.

"""fontwork index-then-font server (v4).
|
|
|
|
Serves the project's real fonts.dir verbatim for the font path and for
|
|
'<path>/fonts.dir', and serves the crafted multi-block font for the font name
|
|
listed in that index (and for anything else that looks like a file). This is
|
|
the closest reproduction of the owner's intended flow with a valid, one-block
|
|
index, so we can see whether the crafted font's own transfer completes.
