Captures the mid-run state of the E4 sweep (35 min in, 41% of trace
served, 0 admission rejections, 0 d_to_p_sync triggers) along with
the interpretation of that observation: under load-floor K=200 + 3D
topology, admission rarely rejects → reseed is rarely needed → D→P
snapshot is a safety net that doesn't fire in the common case.
Includes a fill-in-after-sweep matrix for H1/H2/H3 verdicts and a
follow-up plan (high-pressure variant to force reseed, ablation to
isolate D→P marginal benefit).
