cap's correctness is trusted from its unit test, never stressed against a
simulator that rejects oversized requests.
PR abcip-3.1 layers the **per-device `ConnectionSize` override** on top
(`AbCipDeviceOptions.ConnectionSize`, range `[500..4002]`, see
[`AbCip-Performance.md`](AbCip-Performance.md)). Same gap — `ab_server`
happily honours an oversized override against the CompactLogix profile, so
the legacy-firmware warning + Forward Open rejection that real 5069-L1/L2/L3
parts emit are unit-tested only. Live coverage stays Emulate / rig-only
(connect against a real CompactLogix L2 with `ConnectionSize=1500` to
confirm the Forward Open fails with CIP error 0x01/0x113).
