+  first release the prior device/session state (cancel, ≤ 5 s join, dispose — incl. the AbCip/FOCAS alarm
+  projections) — the device-state half of `ShutdownAsync` only; the poll engine is kept and the actor re-subscribes
+  after every successful init. AbCip publishes fresh tag tables by reference swap (a second init used to throw
+  "tag name collision" on `AdoptConfigDuringInit`); S7 swaps `Plc` under `_gate`.
+- **S7 (#632/#638):** STRING/WSTRING/CHAR/WCHAR and DTL/DATE/TOD/TIME/S5TIME codecs (`S7ValueCodecs`; TOD/TIME/S5TIME

+  `S7Driver.GetDiagnostics()` only — there is no driver-diagnostics surface on `/hosts`.
+- **TwinCAT (#637):** TIME/TOD publish Float64 ms, DATE/DT a UTC DateTime; a tag authored `UDInt` keeps the raw counter
+  (and keeps historizing — DateTime is not historized).
+- **AbLegacy (#636):** `AbLegacyAddress` (in `AbLegacy.Contracts`) is family-aware: PLC-5 `I:`/`O:` indices are OCTAL
+  and are emitted to libplctag as decimal (libplctag's `pccc.c` parses decimal only). MicroLogix function files and
+  indirect `N7:[N7:0]` addresses parse but read `BadNotSupported`. One check (`AbLegacyAddress.Validate`) backs the
+  editor (family-independent) and the deploy gate (family from the tag's `DeviceConfig.PlcFamily`); an unparseable
+  address reads `BadNodeIdUnknown` for that tag only.
+- **OpcUaClient (#635):** OperationLimits are honoured by the SDK session (`SessionClientBatched`) — do not re-add
+  driver-side chunking. Subscription tuning keys are range-checked at `ParseOptions`. `discoveryUrl` endpoints go
+  AFTER configured ones; more than one discovered server without `discoveryServerUri` fails the connect. Session
+  events are the OTel counter `otopcua.driver.opcuaclient.events`. `HistoryAggregateType` carries the full Part 13
+  set; an aggregate the gateway can't serve is `BadAggregateNotSupported` per node.
+- **MTConnect (#627/#628):** TIME_SERIES reads as a variable-length `double[]` (Float64 only); a count disagreeing
+  with `sampleCount` is `BadDecodingError`. One MTConnect driver = one agent client = at most one `/raw` Device
+  (`MTConnectMultipleDevices` deploy error; `RawTreeService.CreateDeviceAsync` refuses a second).

+**Condition children are instance-scoped (#629).** Every child of a materialised condition carries
+`{ConditionId}/{browse path}` in the condition's namespace (e.g. `…/temp_hi/ShelvingState/UnshelveTime`), assigned by
