Gahow Wang 847f52f03b PD-disagg crossover: regular synthetic trace + goodput sweep + figure
gen_synthetic_trace.py --mode regular: maximally-regular multi-turn trace
(fixed prefix/delta/turns, constant arrivals, zero session skew) to isolate
the structural PD cost (per-turn full-context transfer + P/D capacity split)
from the skew/hot-pin artifact.

analysis/crossover/: SLO-goodput PD_advantage sweeps bracketing the
prefill<->decode bottleneck axis (D1 grow input -> prefill-bound; D2 grow
output -> decode-bound). figs/crossover_pd_advantage.png shows the crossover
(y=1) with the agentic operating region annotated.
