http-conformance

hostcheck, a native tool that asks a running Whiskers backend host the same questions as every other host, over HTTP: the real laws of whiskers-conformance (through the Worker's test-mode /_hub window, which carries the changed count the public routes do not), a recorded request script whose answers are written to a transcript, overlapping syncs to one household, a restart of the host, and timings. whiskersd has one household and no test mode, so it is run with --single-household (script, restart and timing only).

See src/ and ../worker/tools/crosscheck, which runs it against all three hosts and compares the transcripts with cmp.
