Static MLA_TC_PREFILL_DISPATCHES 

pub static MLA_TC_PREFILL_DISPATCHES: AtomicU64

Engagement counter for the glm5_next tensor-core MLA prefill chain (MEMRA_MLA_TC_PREFILL), incremented once per (layer, chunk) dispatch at the chain’s own invocation, AFTER the strided-batched GEMM decline check — a declined shape does not count. A gate that must prove “the TC arm ran N times for this workload” reads this delta; the once-per-boot announce line dedups and cannot carry a count (LAW:wiring-assertions-match-prose).
