Rewrite push_monitored_item_body to emit the DataContract field-suffix names from AsbContracts.cs:940-965 (activeField, bufferedField, itemField, sampleIntervalField, timeDeadbandField, userDataField, valueDeadbandField) under prefix `b` bound to the http://schemas.datacontract.org/2004/07/ArchestrAServices.ASBIDataV2Contract namespace. The <Items> wrapper now declares xmlns:b + xmlns:i. The legacy XmlSerializer property names (<Active>, <Item>, <SampleInterval>, <Buffered>) only matter for the canonical-XML HMAC signing input — that emitter at xml_canonical::emit_monitored_item is unchanged and F28 fixture byte-equality still holds for all 13 ops. On the binary NBFX wire MxDataProvider's DataContractSerializer expects the field-suffix form. Wire-byte type encoding matches the captured fixture (add-monitored-items-request-wire.bin): bool → Bool record, ulong → Zero/One/Chars (XmlConvert decimal text), ushort → Zero/One/Int8/Int16/Int32 (smallest-fit binary). Empty string? + null byte[]? emit as empty elements with no <i:nil> attribute (matching the wire). Field order follows the explicit [DataMember(Order = N)] sequence. Adjacent: ItemIdentity is nested via DataContract field names too — NOT the binary <ASBIData> fast-path, which only kicks in at top-level message body members. Verified live against AVEVA MxDataProvider: AddMonitoredItems now returns 1 status item with error_code=0x0000 (previously 0 items; the silent failure was the deliberate DC-schema mismatch); Publish poll #4 delivers the actual tag value as AsbVariant { type_id: 4, length: 4, payload: [99,0,0,0] } through the F26 stream. Pre-existing clippy::format_collect errors in auth.rs:339,342 and client.rs:952 fixed in passing — they were blocking workspace clippy otherwise. Workspace: 757 → 758 tests, clippy -D warnings clean.

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.
