Booted the server against the Modbus seed end-to-end to exercise the
factory wiring shipped in #216 + #217. Surfaced two real issues with
the seeds themselves; fixed both:
1. **Missing ClusterNodeCredential.** `sp_GetCurrentGenerationForCluster`
enforces `ClusterNodeCredential.Value = SUSER_SNAME()` and aborts
with `RAISERROR('Unauthorized: caller sa is not bound to NodeId')`.
All four seed scripts now insert the binding row alongside the
ClusterNode row. Without this, the server fails bootstrap with
`BootstrapException: Central DB unreachable and no local cache
available` (the Unauthorized error gets swallowed on top of the
HTTP fallback path).
2. **Config cache gitignore.** Running the server from the repo root
writes `config_cache.db` + `config_cache-log.db` next to the cwd,
outside the existing `src/.../Server/config_cache.db` pattern. Add
a `config_cache*.db` pattern so any future run location is covered.
## Verified live against Modbus
Booted server against `seed-modbus-smoke.sql` → pymodbus standard
fixture → ran `scripts/e2e/test-modbus.ps1 -BridgeNodeId "ns=2;s=HR200"`:
=== Modbus e2e summary: 4/5 passed ===
[PASS] Probe
[PASS] Driver loopback
[PASS] Server bridge (driver → server → client)
[FAIL] OPC UA write bridge (0x801F0000)
[PASS] Subscribe sees change
The forward direction + subscription delivery are proven working through
the server. The reverse-write failure is a seed-or-ACL issue — server
log shows no exception on the write path, so the client-side status is
coming from the stack's type/ACL guards. Tracking as a follow-up issue
so the remaining three factory wirings can be smoke-booted against the
same pattern.
Note for future runs: two stale v1 `ZB.MOM.WW.LmxOpcUa.Host.exe`
processes from `C:\publish\lmxopcua\instance{1,2}\` squat on ports
4840 + 4841 on this dev box; kill them first or bump the seed's
DashboardPort.

Parent: #209. Adds the server-side wiring so a Config DB `DriverType='Modbus'`
row actually boots a Modbus driver instance + publishes its tags under OPC UA
NodeIds, instead of being silently skipped by DriverInstanceBootstrapper.
Changes:
- `ModbusDriverFactoryExtensions` (new) — mirrors
`GalaxyProxyDriverFactoryExtensions` + `FocasDriverFactoryExtensions`.
`DriverTypeName="Modbus"`, `CreateInstance` deserialises
`ModbusDriverConfigDto` (Host/Port/UnitId/TimeoutMs/Probe/Tags) to a full
`ModbusDriverOptions` and hands back a `ModbusDriver`. Strict enum parsing
(Region / DataType / ByteOrder / StringByteOrder) — unknown values fail
fast with an explicit "expected one of" error rather than at first read.
- `Program.cs` — register the factory after Galaxy + FOCAS.
- `Driver.Modbus.csproj` — add `Core` project reference (the DI-free factory
needs `DriverFactoryRegistry` from `Core.Hosting`). Matches the FOCAS
driver's reference shape.
- `Server.csproj` — add the `Driver.Modbus` ProjectReference so the
Program.cs registration compiles against the same assembly the server
loads at runtime.
- `scripts/smoke/seed-modbus-smoke.sql` (new) — one-cluster smoke seed
modelled on `seed-phase-7-smoke.sql`. Creates a `modbus-smoke` cluster +
`modbus-smoke-node` + Draft generation + Namespace + UnsArea/UnsLine/
Equipment + one Modbus `DriverInstance` pointing at the pymodbus standard
fixture (`127.0.0.1:5020`) + one Tag at `HR[200]:UInt16`, ending in
`EXEC sp_PublishGeneration`. HR[100] is deliberately *not* used because
pymodbus `standard.json` runs an auto-increment action on that register.
Full-solution build: 0 errors, only the pre-existing xUnit1051 warnings.
AB CIP / S7 / AB Legacy factories follow in their own PRs per #211 / #212 /
#213. Live boot verification happens in the exit-gate PR once all four
factories are in place.
