Provisioned 7 new UDAs on $TestMachine via wwtools/graccesscli
object uda add (then deployed to TestMachine_001):
TestFloat MxFloat scalar
TestFloatArray MxFloat array (4)
TestDouble MxDouble scalar
TestDoubleArray MxDouble array (4)
TestDateTime MxTime scalar
TestDuration MxElapsedTime scalar
TestDurationArray MxElapsedTime array (4)
New crates/mxaccess/examples/asb-type-matrix.rs reads all 14 tags
(7 pre-existing + 7 new) in a single batch and dumps the live
AsbVariant bytes per tag when MX_ASB_DUMP_FIXTURES=<dir> is set.
Single-attempt register (no retry — F31 InvalidConnectionId
cool-down re-arms on every retry, making backoff
counter-productive; if the cool-down is engaged, wait 60+ seconds
without ASB activity then re-run).
Captured live evidence (single cold-start run, all 14 register
calls returned error_code=0x0000):
TestChangingInt type_id=4 (Int32) length=4 payload=4
TestAlarm001 type_id=17 (Boolean) length=1 payload=1
MachineCode type_id=10 (String) length=30 payload=30
TestFloat type_id=8 (Float) length=4 payload=4
TestDouble type_id=9 (Double) length=8 payload=8
TestDateTime type_id=11 (DateTime) length=8 payload=8
TestDuration type_id=12 (ElapsedTime) length=8 payload=8
TestIntArray, TestBoolArray, TestStringArray, TestDateTimeArray,
TestFloatArray, TestDoubleArray, TestDurationArray
type_id=0 length=0 payload=0
(provisioned but no value written yet)
Per-tag fixture .bin files saved under
crates/mxaccess-codec/tests/fixtures/f51-type-matrix/ — full
14-byte to 40-byte AsbVariant byte sequences (i32 type_id LE +
i32 length LE + payload bytes).
crates/mxaccess-codec/tests/f51_type_matrix_parity.rs round-trips
each scalar fixture: decode -> re-encode -> assert byte-equal +
type_id / length pin. Tests skip with [skip] message when fixtures
are absent (so the suite passes on a fresh checkout without live
captures). 7 scalar tests pass against the captured fixtures.
Array tags excluded from round-trip pinning because the live
engine returns empty payloads for unwritten arrays. Codec-side
array round-trip is covered by asb_variant's existing synthetic-
payload unit tests.
docs/galaxy-test-fixtures.md inventories all $TestMachine UDAs
(pre-existing + F51-provisioned), the graccesscli provisioning
recipe, the fixture-regeneration pattern, and the F31 cool-down
caveat.

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.
