Task 2 review follow-up. The plan specified MqttEquipmentTagParser.TryParse(reference)
with def.Name = the TagConfig blob, and told us to mirror a type named
ModbusEquipmentTagParser. Both are plan defects:
- EquipmentTagRefResolver documents that a v3 driver reference "is now always a
RawPath" and that the blob-parse fallback is retired. Keying Name by the blob
would make OnDataChange publish under a reference that never matches the
RawPath-keyed fan-out in DriverHostActor - silently dead in production with
every unit test still green.
- ModbusEquipmentTagParser does not exist. The six sibling drivers all use
<Driver>TagDefinitionFactory.FromTagConfig(tagConfig, rawPath, out def).
Changes:
- Rename MqttEquipmentTagParser -> MqttTagDefinitionFactory; TryParse(reference,
out def) -> FromTagConfig(tagConfig, rawPath, out def) setting Name: rawPath,
matching ModbusTagDefinitionFactory's structure, param docs and guard order.
- Pin the identity contract with a dedicated test so a regression to blob-keying
goes red.
- Read qos with the same strictness as the enums: a present-but-invalid qos
("high" / 1.5 / 5 / null) now rejects the tag and is warned by Inspect,
instead of being silently absorbed into the driver-level default and handing
the operator a weaker delivery guarantee than the one they authored.
- No ToTagConfig inverse: the siblings carry one solely for their Driver.<X>.Cli
project, the MQTT plan defines none, and the AdminUI editor template
references no driver factory. Recorded as an explicit YAGNI call in the type
doc rather than added speculatively.
