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.

gen_synthetic_trace (vanilla Poisson, zero prefix reuse — the regime where
PD-disagg is expected to win), mutate_trace (morph reuse/burst/skew toward
the agentic regime), and plot_crossover. Emits the replayer's JSONL schema.
