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.
Equipment tags were stuck at Bad_WaitingForInitialData on the deployed driver: the equipment poll, fixed-tree loop, probe and recycle shared one FOCAS/2 socket with no serialization, and the steady-state read had no timeout — concurrent reads collided and a stalled read hung forever, never overwriting the node's initial-data seed.
- SynchronizedFocasClient: per-device SemaphoreSlim gate + per-call timeout around every wire op (Connect/Probe gated, not double-bounded); wired in EnsureConnectedAsync. ReadAsync/WriteAsync map a per-call timeout to BadCommunicationError instead of rethrowing.
- FlexibleStringConverter on FOCAS config Series: the AdminUI persists the enum as a number ("series":6); accept number-or-string instead of throwing -> stub.
- FocasHostAddress.TryParse tolerates a scheme-less {ip}[:{port}] (AdminUI hostAddress form); canonical focas:// unchanged, malformed schemes still rejected.
247 FOCAS tests green; each fix has a regression test. Live-validated on wonder-app-vd03 (tags read Good).
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.
Equipment tags resolved at runtime via FocasEquipmentTagParser were not
seeded in _parsedAddressesByTagName so both ReadAsync and WriteAsync
re-parsed the raw TagConfig JSON address string on every hot-path call.
Promoted the field to ConcurrentDictionary (read + write thread safety)
and introduced ResolveParsedAddress(GetOrAdd) so the first call stores
the parse result and all subsequent calls are a cache hit. Authored tags
seeded at InitializeAsync compile and work unchanged.
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.

Throw InvalidOperationException at InitializeAsync when a tag's
DeviceHostAddress does not match any entry in the Devices list, naming
both the tag and the unresolved host. Previously the missing-device
check was guarded by a TryGetValue so a typo silently bypassed
capability-matrix validation and deferred the error to per-read
BadNodeIdUnknown — the opposite of the documented "fail at load" goal.
Also resolves findings 004, 005, and 006 in the same file:
- 004: DiscoverAsync now unconditionally emits ViewOnly for all user
tags; the Writable config field no longer influences security class
because the wire backend always returns BadNotWritable.
- 005: All _health reads use Volatile.Read and all writes use
Volatile.Write so concurrent readers observe a consistent reference
and read-modify-write sequences capture a stable snapshot.
- 006: EnsureConnectedAsync disposes and nulls any existing
non-connected client before creating a fresh one, preventing
ObjectDisposedException loops after a HandleRecycle race or teardown.

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.
