CIP codec (#564): PatchU16 bounds guard; CipReply content equality; CipPath port/length/ASCII/odd/oversize validation with ArgumentException for malformed tag names and routes; CipPath.MessageRouter/ConnectionManager are now ReadOnlySpan<byte>; refused Forward Open surfaces ForwardOpenRefusedException with structured general/extended status; test CaptureFile uses BinaryPrimitives. EncapsulationClient (#565): frame write bounded by the exchange timeout, which faults (never cancels) the connection; finite positive timeouts enforced at every entry point; gate wait bounded by the timeout; deterministic reorder of the 300 ms test; new dispose-during-drain, gate-wait and RegisterSession zero-context tests.
