published tag must be **writable** — stages 4 + 5 will fail against a
read-only tag.
## Status
Stages 1 + 2 (driver-side probe + loopback) are verified end-to-end
against the pymodbus / ab_server / python-snap7 fixtures. Stages 3-5
(anything crossing the OtOpcUa server) are **blocked** on server-side
driver factory wiring:
- `src/ZB.MOM.WW.OtOpcUa.Server/Program.cs` only registers Galaxy +
FOCAS factories. `DriverInstanceBootstrapper` skips any `DriverType`
without a registered factory — so Modbus / AB CIP / AB Legacy / S7 /
TwinCAT rows in the Config DB are silently no-op'd even when the seed
is perfect.
- No Config DB seed script exists for non-Galaxy drivers; Admin UI is
currently the only path to author one.
Tracking: **#209** (umbrella) → #210 (Modbus), #211 (AB CIP), #212 (S7),
#213 (AB Legacy, also hardware-gated — #222). Each child issue lists
the factory class to write + the seed SQL shape + the verification
command.
Until those ship, stages 3-5 will fail with "read failed" (nothing
published at that NodeId) and `[FAIL]` the suite even on a running
server.

NOTE: HR[200] (not HR[100]) — pymodbus standard.json makes HR[100] an
auto-incrementing register that mutates every poll, so loopback writes
can't be verified there.
