frank-small: seam follows the f16 K + q8_0 V contract from 1862dc3

1862dc3 repriced the Ornith rung (nine full-attn layers: f16/f16 = dead
boot) and flipped CACHE_TYPE_V to q8_0, but its note that the seam was
'retargeted in 8f53df7' covered only the payload paths — the KV test
still asserted the 2026-10-03 unquantized-both-halves contract and held
the suite red. Test now pins the shipped contract: K=f16, V=q8_0,
flash-attn on.
