.NET's `XmlBinaryWriter.WriteBase64` chunks the byte array into multiple consecutive NBFX `Bytes8/16/32` records when the total exceeds the per-record budget. Live capture of a successful .NET RegisterItemsResponse showed the Status ASBIData payload split into `Bytes8(78) + Bytes8WithEndElement(1)` — total 79 bytes. Our decoder walked tokens looking for a single `Text(Bytes(...))` after each `<ASBIData>` element and stopped at the first chunk, returning a truncated payload that hit `Codec(ShortRead)` when the consumer tried to decode an ItemStatus from the partial bytes. Fix: walk **all** consecutive `Text(Bytes)` tokens after `<ASBIData>` and concatenate into a single payload before pushing to the result vector. Mirrors WCF's reader behaviour, which reassembles the chunks into one byte array via `XmlReader.ReadElementContentAsBase64`. Workspace: 710 unit tests pass. Live state: AuthenticateMe is accepted, RegisterItemsResponse decodes structurally — the remaining "MissingField Status" error reflects a server-side semantic outcome (server returned empty Status array) rather than a protocol bug, likely tag-resolution related and outside F28's scope.

mxaccess (Rust port)
Native Rust replacement for AVEVA / Wonderware MXAccess. See ../design/ for
the architectural specification, ../src/ for the .NET reference (the
executable spec), and ../CLAUDE.md for project-wide rules.
Status
M0 — Workspace skeleton. Stub types compile; nothing is implemented yet.
See ../design/60-roadmap.md for the M0–M6 milestone plan.
