Adds <summary>/<param>/<returns>/<inheritdoc> where missing and removes
project bookkeeping IDs (task/tracking refs) from shipped code comments,
so the docs read cleanly and CommentChecker is quiet except for known
false positives (PLC/protocol terms, event/IEqualityComparer inheritdoc).
Doc/comment-only; no logic changed; solution builds clean.
First real FOCAS hardware contact (Makino Pro 5 / 31i-B @ 10.201.31.5). A full
v3 data-PDU capture corrected the initial diagnosis: the v3 block envelope is
identical to v1, so only specific payload structs / request math / one client
robustness gap were wrong — not "framing rewrites".
Fixes (all re-validated live through the fixed driver):
- version gate: accept inbound PDU {1,3}, keep emitting v1 (FocasWireProtocol).
- cnc_rdtimer: 8-byte {minute,msec} payload is little-endian (ParseTimer) — the
only decode with an in-range msec field.
- pmc_rdpmcrng: request range widened to the data-type byte width
(end = start + width - 1) so a Word/Long isn't truncated to 0 values
(was spurious BadOutOfRange); decode extracted to ParsePmcRange.
- cnc_rdsvmeter: per-axis LOADELM is 8 bytes (not 12) and names come from the
0x0089 block — ParseServoMeters fixes the misaligned 655360 garbage. Also the
"hang" was NetworkStream.ReadAsync not aborting a stalled socket: ReadExactlyAsync
now disposes the stream on cancellation so a stalled peer can't wedge a poll loop.
- cnc_rddynamic2: contract guard rejecting axis < 1 (driver poll already 1-based).
- FocasDriverProbe: run a real wire session (initiate + cnc_statinfo) instead of
degrading to Ok=true "TCP reachability only" when FWLIB is absent — a bare TCP
listener no longer reports HEALTHY.
cnc_rdparam (0x000e) is unsupported on this control — EW_FUNC across 14
request-framing variants x 4 known-present params; needs a reference FWLIB trace
or is restricted. Deferred (deployed config uses macros, not parameters).
Tests: FOCAS suite 234 green (+16), full solution builds 0 errors. Raw v3
captures checked in under tests/.../Fixtures/v3/. Capture tools under scripts/focas/.

Add IFocasClientFactory.EnsureUsable() — a config-time probe called by
FocasDriver.InitializeAsync before any background loops start. The
UnimplementedFocasClientFactory throws NotSupportedException immediately
(faulting the driver at init), eliminating the footgun where a driver on
the 'unimplemented' backend appeared Healthy then failed every read/write/
subscribe silently. WireFocasClientFactory and FakeFocasClientFactory are
no-ops. Backstop Create() throw remains in place.
Adds <summary>, <param>, <typeparam>, and <inheritdoc/> tags to public
members surfaced by commentchecker — resolves 5,847 of 5,869 issues
(99.6%) across three /fixdocs passes.
- Driver.FOCAS-007: optional ILogger<FocasDriver> + alarm-projection
logger; log Debug around every formerly-empty catch (probe / shutdown
/ fixed-tree / recycle / alarms-read / projection).
- Driver.FOCAS-008: cache the parsed FocasAddress per tag at
InitializeAsync; Read/WriteAsync look it up instead of re-parsing on
every call.
- Driver.FOCAS-009: ProbeLoopAsync now wraps client.ProbeAsync in a
linked CTS honouring Probe.Timeout so a hung CNC socket can't block
past the configured limit.
- Driver.FOCAS-010: FocasOperationModeExtensions.ToText delegates to
FocasOpMode.ToText — single canonical op-mode label surface.
- Driver.FOCAS-011: FocasAlarmType constants are typed short to match
the cnc_rdalmmsg2 wire field and the projection switch arms.

Driver.FOCAS-001: FocasDriverConfigDto exposed no FixedTree / AlarmProjection /
HandleRecycle sections, so a deployment that opted into those features per
docs/drivers/FOCAS.md had the sections silently dropped by case-insensitive
JSON parsing and the features stayed at their disabled defaults. Added
FocasFixedTreeDto / FocasAlarmProjectionDto / FocasHandleRecycleDto and Build*
mappers in CreateInstance that populate the matching FocasDriverOptions
properties; a missing section or field keeps its existing default.
Driver.FOCAS-002: the fixed-tree bootstrap probe classified ProgramInfo as
"supported" whenever GetProgramInfoAsync returned non-null, but WireFocasClient
.GetProgramInfoAsync substituted defaults instead of throwing on a FOCAS error
return, so a CNC series answering EW_FUNC/EW_NOOPT for cnc_exeprgname2 /
cnc_rdopmode still got the Program/ and OperationMode/ subtrees. The method now
throws InvalidOperationException when neither the program-name nor the op-mode
read is IsOk, so SafeTryProbe correctly suppresses the capability.
Added FocasFactoryConfigTests covering the three opt-in config sections
round-tripping through CreateInstance and the fixed-tree bootstrap classifying
ProgramInfo as unsupported when the probe throws. Added an internal
FocasDriver.Options test seam.

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.
