loopyt fece5d9047 test(h20): catch a factory that returns nothing before eight ranks do
An edit of mine dropped a `return launch` from `finalize_verification_tl`. The A/B case for
that kernel was not re-run, so nothing local objected; the failure surfaced as a TypeError
inside the sampler of an end-to-end run, once per rank. The harness now checks that every
`*_tl` symbol the selected backend exports is callable, which turns that class of mistake
into one line printed before any case executes.

Also records where the remaining sixteen kernels actually sit. None of them is
unconditionally on the path, but the distribution is lopsided and the document had it
backwards in one place: the three `candidate_*` kernels are not merely "off on SM90", they
are switched off *by* `PLATFORM.is_sm90` -- and this checkpoint sets
`candidate_source_layer_id=20` of 40 layers. On a card where `is_sm90` is False, that is
nineteen layers on every step, which is the opposite of optional. Their harder blocker is
noted alongside: that path also needs `deep_gemm.fp8_fp4_sparse_mqa_logits`, which is
SM100-only, so porting those three alone would buy nothing.

The four kernels that no production path reaches are listed as such, so nobody spends an
afternoon on them.
