Fused Attention

fused_attention exercises the combined memory and arithmetic pressure of a causal attention path using a synthetic context working set.

pantheon --test fused_attention --duration 60 --gpu 0 --mem 50 --verify --profile

Area	What it tests
Context access	Repeated windowed reads through synthetic attention state.
Compute	Attention-score and projection-style fused arithmetic.
Telemetry	SM activity, cache behavior, DRAM traffic, clocks, power, and thermals.
Result	Synthetic attention tiles per second.

It isolates hardware behavior of an attention-like path. It does not implement or validate a framework's FlashAttention kernel or model output.
