Review round 1 on the golden frames: - Re-captured logix-read-dint-array16 (element i = ((i+1)<<24)|(i+1)) and logix-read-bool (= 1) so neither decode oracle is all zeros. ab_server rejects libplctag's own BOOL write with CIP 0x03 (two data bytes for a one-byte BOOL), so the BOOL is seeded by a raw UCMM Write Tag (client seed-bool). - Committed the capture client as scripts/ab-capture/client (outside the slnx, CPM off, libplctag 1.5.2 pinned); capture.sh gains a `client` subcommand. - README documents simulator-only behaviour: zeroed reply sender context, STRING typed D0 00 instead of A0 02 + handle, and the BOOL write refusal. - capture.sh no longer claims UnregisterSession reaches the wire (session ends in RST). - CaptureFileTests also check the CPF walk ends at the frame end and that every reply service is its request service | 0x80.
