- Ab.Transport: AbOpcUaStatusMap is the single AbStatus->OPC UA table; AbCip/AbLegacy mappers delegate. - Remove dead MapCipGeneralStatus / MapPcccStatus / AbLegacy MapException (+ tests). - LibplctagOrphanRelease is one source file (Ab.LibplctagShared) compiled into both drivers. - LibplctagConfinementGuardTests: tokenising comment/literal stripper, block comments, csproj PackageReference guard. - LibplctagStatusTranslationTests: real LibPlcTagException round trip, WrapSync/Wrap OCE pass-through, adapter routes decode via WrapSync. - AbCipTypeMismatchTests: libplctag width-mismatch path (BadTypeMismatch, handle kept, no Degraded, warn once). - Host: AddAbCipDriverDefaults extension + Program.cs source pin for Drivers:AbCip:DefaultTransport. - docs/drivers/AbCip.md: layout rows + benign Degraded-after-outage note.
