- Driver.AbCip-007: inject an optional ILogger<AbCipDriver> /
ILogger<AbCipAlarmProjection> (default NullLogger) and log around
every read / write / template-fetch / probe / alarm-poll failure path.
- Driver.AbCip-011: LogWarning when InitializeAsync is configured with
Probe.Enabled=true but ProbeTagPath is blank — operators now see why
GetHostStatuses keeps reporting Unknown.
- Driver.AbCip-012: documented the LibplctagTemplateReader per-call
Tag cost as accepted given libplctag's own connection pool and the
low-frequency discovery use-case.
- Driver.AbCip-013: per-device AllowPacking + ConnectionSize overrides
on AbCipDeviceOptions, threaded through AbCipTagCreateParams; central
BuildCreateParams helper replaces five ad-hoc clones; AllowPacking
now reaches Tag.AllowPacking at runtime.
- Driver.AbCip-015: stale-comment sweep — every PR-N forward-reference
is rewritten to describe present behaviour.

Finding 005 revised approach: keep the parent Structure tag in
`_tagsByName` so the whole-UDT grouping planner can find it (required
for Driver.AbCip-003 opt-in path + alarm projection). Instead, detect a
direct read of a Structure-with-Members in `ReadSingleAsync` and return
`BadNotSupported` rather than Good/null — explicitly documenting the
contract that callers must address member paths. Duplicate-key checks
(scalar and member fan-out) remain.
Finding 014 test corrections: `Structure_parent_tag_read_returns_BadNotSupported`
now asserts the new contract. `Read_UDInt_tag_returns_uint_value_not_negative_wrapped_int`
assertion fixed to use `ShouldBeOfType<uint>()` instead of
`ShouldNotBe(-1)` (Shouldly overflows comparing uint.MaxValue with int).

Add regression tests for the Medium findings resolved in this series:
- AbCipDataType_maps_large_integer_types (theory: LInt→Int64, ULInt→UInt64,
UDInt→UInt32) and Read_UDInt_tag_returns_uint_value_not_negative_wrapped_int
cover Driver.AbCip-004.
- Structure_parent_tag_is_not_readable_after_member_fan_out,
InitializeAsync_throws_on_duplicate_tag_name, and
InitializeAsync_throws_when_member_name_collides_with_independent_tag
cover Driver.AbCip-005.
- Read_failure_evicts_runtime_so_next_read_creates_fresh_handle covers
Driver.AbCip-010.
AbCipDriverTests.AbCipDataType_maps_atomics_to_driver_types extended with
LInt/ULInt/UDInt assertions.

`PlcTagHandle` and `DeviceState.TagHandles` were dead scaffolding: the
`ReleaseHandle` no-op never called `plc_tag_destroy` and the dict was
never populated. Removed the file, the dead dict, and its
`DisposeHandles` loop. Updated the `AbCipDriver` class doc to document
that native lifetime is owned by libplctag.NET `Tag.Dispose()` (invoked
from `DisposeHandles`) with the library's own finalizer covering any
GC-collected instances. Two test methods that only exercised the dead
`PlcTagHandle` class removed from `AbCipDriverTests`.

Driver.AbCip-001 — ReinitializeAsync silently discarded its config JSON.
Extracted AbCipDriverFactoryExtensions.ParseOptions; InitializeAsync now
re-parses a content-bearing driverConfigJson and replaces _options (and
recreates the alarm projection), so a reinitialize with a changed config
(new device/tag, changed timeout) actually takes effect. A blank or
empty-object JSON keeps construction-time options for the unit-test seam.
Driver.AbCip-002 — libplctag status mapping used wrong integer constants.
MapLibplctagStatus now switches on the libplctag.NET Status enum members
(Ok/Pending/ErrorTimeout/ErrorNotFound/ErrorNotAllowed/ErrorOutOfBounds/…)
instead of hand-typed natives, so timeout/not-found/not-allowed/out-of-bounds
get their specific OPC UA codes instead of all collapsing to
BadCommunicationError. The int overload casts to Status to stay correct
against the wrapper's contiguous renumbering.
Driver.AbCip-003 — whole-UDT reads decoded members at declaration-order
offsets, which Studio 5000 does not guarantee. Added the opt-in
AbCipDriverOptions.EnableDeclarationOnlyUdtGrouping flag (default false);
AbCipUdtReadPlanner.Build forms no groups when it is off, so by default
every UDT member reads per-tag rather than at possibly-wrong offsets.
Driver.AbCip-008 — probe loops were fire-and-forget and ShutdownAsync raced
them. Each probe Task is stored on DeviceState.ProbeTask; ShutdownAsync now
cancels every CTS, awaits each probe Task (10s timeout), then disposes the
CTS and handles. DeviceState.Runtimes/ParentRuntimes are ConcurrentDictionary
and the Ensure*RuntimeAsync paths use TryAdd, disposing the losing concurrent
creator instead of leaking a native tag handle.
Adds AbCipDriverCodeReviewRegressionTests and updates existing AbCip tests
to the corrected status constants + opt-in grouping flag. AbCip driver +
test project build clean; all 244 AbCip tests pass. (The full-solution
build has pre-existing, unrelated Driver.Galaxy protobuf-generation errors
in this worktree.)

Group all 69 projects into category subfolders under src/ and tests/ so the
Rider Solution Explorer mirrors the module structure. Folders: Core, Server,
Drivers (with a nested Driver CLIs subfolder), Client, Tooling.
- Move every project folder on disk with git mv (history preserved as renames).
- Recompute relative paths in 57 .csproj files: cross-category ProjectReferences,
the lib/ HintPath+None refs in Driver.Historian.Wonderware, and the external
mxaccessgw refs in Driver.Galaxy and its test project.
- Rebuild ZB.MOM.WW.OtOpcUa.slnx with nested solution folders.
- Re-prefix project paths in functional scripts (e2e, compliance, smoke SQL,
integration, install).
Build green (0 errors); unit tests pass. Docs left for a separate pass.
