Wave-B driver re-keying. Under v3 the server addresses Galaxy nodes by RawPath
and the driver dials the Galaxy attributeRef (tag_name.AttributeName). The
dialled address moved into TagConfig under the camelCase key `attributeRef`
(renamed from the pre-v3 PascalCase FullName) and rides on RawTagEntry.
Options + factory:
- GalaxyDriverOptions gains `IReadOnlyList<RawTagEntry> RawTags` (Contracts now
references the zero-dep Core.Abstractions leaf for RawTagEntry — same as
Modbus.Contracts). Factory binds `List<RawTagEntry>? RawTags` from DriverConfig.
Boundary translation (built once from options.RawTags):
- RawPath -> attributeRef (forward dial) on Read / Write / Subscribe / Ack.
- attributeRef -> RawPath (reverse) on the value fan-out (OnDataChange) and the
alarm ConditionId — so the alarm resolves back to the same RawPath the value
path surfaces. Both legs fall back to identity on a miss, so the live-browse
discovery path (no authored tags) and synthetic alarm sub-refs
(attributeRef.InAlarm) dial straight through unchanged.
- WriteAsync dials the attributeRef but resolves security via the RawPath-keyed
map the discoverer captured (reverse-maps in the resolver closure).
Discovery + alarms:
- GalaxyDiscoverer emits FullName = RawPath for authored attributes (falls back
to attributeRef), threads RawTagEntry.WriteIdempotent onto DriverAttributeInfo,
and gains an optional attributeRef -> RawTagEntry resolver ctor param.
- AlarmRefBuilder.Build(conditionReference, dialReference): SourceName/ConditionId
= RawPath identity; the five live-state/ack sub-refs dial off the attributeRef.
ReinitializeAsync equivalence now compares the session-shape sections field-wise,
excluding RawTags (address-space state re-applied via rediscovery, and a record's
synthesized equality would compare the lists by reference).
Tests: +9 (discoverer RawPath/WriteIdempotent + alarm identity; factory RawTags
binding; driver read/write/subscribe/alarm boundary translation). Existing 304
preserved via identity fallback. 313 pass, 5 live-gated skips.
