7d04aef replaced the byte-exact USAGE pin with a shape check that requires
every long flag grepped from the healthcheck source to appear in --help.
--json was already undocumented before this task, so that check was red on
arrival and it also dropped the 'unknown flag ignored' assertion on --bogus,
the only pin on the no---strict silent-ignore path.
The accepted plan's phase 3 is 'no edit': --help is untouched by --strict, so
master's version passes as-is.
