Ettore Di Giacinto 24833f0966 docs(paged): bf16 SSM-state NO-SHIP - fails f32 KL gate (= vLLM's own precision)
De-risk passed (test-backend-ops 52/52 bf16, f32 default byte-identical to 0023),
and the throughput lever is real (recurrence -49%/call, dense ~490 t/s = 125% of
vLLM clean). But bf16-vs-f32 KLD is 0.06-0.17 at >=1024 ctx (threshold 1e-3) with
~90% top-token agreement: intrinsic bf16 error over gated-DeltaNet long-memory
heads, not a bug. That is exactly vLLM's own bf16 GDN precision. Shelved; ship the
95% bit-exact f32 plateau (0018-0023). bf16 work backed up on DGX (BF16_SSM_STATE.diff).
