Second security review:
- a broadcast counts once against the queued-bytes budget; each block of
addresses gets at most an eighth; when the budget runs out the biggest
consumer is shed, not the receiver
- forced compactions at most once a minute per file
- plugin downloads check the per-address share before the global budget
and before reading
- install.sh never replaces a Caddyfile with other sites (one import line,
once; install-test.sh in packaging lint); the built binary runs only as
the server's account
- bytes being read count against per-block and global budgets, the
biggest readers dropped first
- block multipliers x2 (/56) and x4 (/48), connection caps at most a
sixteenth/eighth of all; global publish and download budgets eight times
a /48's share
- problems capped at 200; writes refused below max(1 GiB, two files) free;
the private-server file cap documented
