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.
