arti 3a51b95317 harness/fontwork: reproduction scripts for the TFTP Disk-full investigation
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.
