An ALARM: address (*, <Type>, <Type>/<n>, <Type>/<lo>-<hi>, T<code>, OTHER) on a raw tag that
also carries the cross-driver alarm object is ONE condition with ConditionId == RawPath and a
Kind (Raise / Retrigger / Clear), so DriverHostActor.ForwardNativeAlarm routes it and
NativeAlarmProjector activates it. Fixes all seven triage defects:
1. SubscribeAlarmsAsync treated the host's RawPaths as device hosts -> nothing polled.
2. Decorated "{host}#{Type}:{Number}" ConditionId -> every event dropped.
3. No Kind -> projector kept prior state.
4. WireFocasClient.ReadAlarmsAsync answered [] on failure -> mass clear + un-acked re-raise.
It now throws; a failed device read keeps every condition's state.
5. Acks lost on reconnect -> told-record dedup (MTConnect #626 pattern) held for the driver's
lifetime; same-set re-subscribe / re-init re-raise nothing; changed set prunes leavers only.
6. Subscribe threw while AlarmProjection.Enabled=false -> the tag is the opt-in; flag is a no-op.
7. Alarm tags could not be authored -> ALARM: grammar (FocasAlarmSelector, Contracts) backs the
editor, the address picker, the deploy-time inspector and driver init.
Severity: authored alarm.severity -> exact OpcUaSeverity; else the 16i-era type bucket. The type
table stays the only one (moved to Contracts, documented 16i-era; 30i codes not invented; raw
T<code> selector + raw code in every message). Read-only: ack is server-side. Also clears the
value table on a re-initialise (#630 gap that let a removed/moved tag keep reading).
E2E: Runtime.Tests FocasNativeAlarmEndToEndTests drives the real driver through the real
DriverHostActor and asserts the condition goes Active then inactive.

The mock had served the shapes the driver once agreed with it on, so it
validated the very defects just fixed: it ANSWERED the non-existent 0x00D3
cnc_getfigure, wrote base/exponent 0/0 into position blocks, put the macro
decimal at offset 4, and served spindle 'max rpm' as a raw constant.
Ported from the sister ignitionoee mock (local divergence recorded in
VENDORED.md; the LE timer and alarm cap are kept):
- 0x00D3 refused with EW_FUNC, as the real control does.
- 0x0026 blocks carry base 10 / position_figures exponent; signed arg2,
arg2 = 0 or past the axis count refused EW_ATTRIB.
- cnc_rdmacro is the 8-byte ODBM shape, 9-digit mantissa, unset = vacant.
- servo/spindle meter records carry the envelope; spindle meters are
1/16384-of-full-scale counts (motor speed = speed / max_rpm).
Integration tests: spindle test reads Load/MotorSpeedPct percentages; the
position-scale test now proves the block's own scale wins; new
Vacant_positions_and_macros_read_bad_over_the_wire. 12/12 pass against the
mock run locally (python -m focas_mock.cli serve, OTOPCUA_FOCAS_SIM_ENDPOINT).
Replace pre-declared options.Tags (typed <Driver>TagDefinition lists) with
options.RawTags (IReadOnlyList<RawTagEntry>) across all 6 Docker-gated driver
integration suites so they COMPILE against the v3 driver API.
Each project gets a local <Driver>RawTags helper mirroring the unit-test
project's helper: it serialises a typed def back to its TagConfig blob via the
driver's <Driver>TagDefinitionFactory.ToTagConfig and packages it as a
RawTagEntry (RawPath = def.Name; DeviceName = def.DeviceHostAddress for the
multi-device drivers AbCip/AbLegacy/TwinCAT/FOCAS). Test intent (addresses,
data types, device routing, assertions) is unchanged — only the
tag-authoring/config-delivery shape was migrated.
Docker-gated: these still skip at runtime without fixtures; COMPILE is the gate.
Two test/fixture bugs; NO OtOpcUa driver change.
1. Topology: FocasSimFixture reads an env-overridable endpoint
(OTOPCUA_FOCAS_SIM_ENDPOINT, default localhost:8193) and exposes Host/Port,
but WireBackendTests + WireBackendCoverageTests hardcoded
focas://127.0.0.1:8193. Against a remote fixture the skip-gate passed
(remote reachable) but the driver dialed localhost -> KeyNotFound. Added a
DeviceUri property to the fixture; each test now derives DeviceHost from it.
Recovered 8 of 9.
2. Mock timer endianness (surfaced once #1 let the tests reach the mock): the
last failure read 60397977600 for a 3600 s power-on timer (= 0x3C000000 x 60).
The focas-mock's _wire_timer encoded the minute/msec fields big-endian (_u32),
but cnc_rdtimer's timer fields are LITTLE-endian on real hardware — a
documented, live-31i-B-validated quirk that FocasWireClient.ParseTimer decodes
LE (docs/plans/2026-06-25-focas-pdu-v3-30i-b-support.md). The driver was
correct; the mock was wrong. _wire_timer now emits little-endian (_u32_le).
Suite 9F/1P -> 10/10 against the remote fixture at ~/otopcua-focas.
Integration-sweep follow-up #3.
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.
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.
