Every foreign fixture differed from the mind's name in its bytes, so a check
folding case passed both suites. A slug label is `[A-Za-z0-9_-]{1,64}`:
uppercase is legal, `Yggdrasil` and `yggdrasil` are two names a client may
declare and two minds a host may hold, and a comparison that folds case
answers one of them for the other. Soul found the mutant alive.
`CASED_INSTANCE` stands beside the near and prefixed names in the mind
fixtures and `CASED` beside them in the daemon's, and each test asserts the
relation it relies on before using it: the cased name lowercases to the mind's
and is not equal to it.
`D1L5` folds case against the mind suite and `D1DL2` against the daemon suite,
so both fixture sets are load-bearing rather than only the one.
