The driver accepts `IAbLegacyTagFactory` via ctor DI; every test
supplies a `FakeAbLegacyTag`.
## Per-transport suites and capture recipe
The `AbLegacy.IntegrationTests` suites now run **once per transport** (`TransportMatrix`: `Libplctag` and
`Native`). Set `AB_LEGACY_COMPOSE_PROFILE` to the running profile. On the 2026-10-07 run native passed
everything libplctag passed on `slc500`, `micrologix` and `plc5` (the PLC-5 test reads N7 only, so the PLC-5
refusal paths and status-bit writes are not exercised by it). Native PCCC is **simulator-only**. Write-capable
tests (the SLC500 N7:5 round trip) require `AB_SERVER_ALLOW_WRITES=1`. Golden frames:
`scripts/ab-capture/capture.sh`, fixtures under
`tests/Drivers/ZB.MOM.WW.OtOpcUa.Driver.Ab.Transport.Tests/Captures/`. Evidence:
[native-ab-transport-gate-results](../plans/2026-10-07-native-ab-transport-gate-results.md).
