N3: a keyless blob carrying the addressResolved marker was served from its
string by the driver but saved as HR[0] by the editor model / CSV path. The
precedence rule now lives in ONE pure resolver in Driver.Modbus.Contracts
(ModbusTagAddressResolution.Classify/Resolve): keys when region+address are
both present, else a string-only addressString resolved with the driver's
family (refused when it cannot parse), else refused. The marker never decides.
Consumers that now ask it instead of restating it: the driver's tag reader
(ModbusTagDefinitionFactory.FromTagConfig), the deploy gate (Inspect /
DescribeRejection), the editor model (AddressShape / IsStringOnly /
HasKeyAddress / ResolveWith, ToJson stamping, Validate), the CSV export cells
and the editor hint. The model writes keys only when it loaded them or a field
was authored - never defaults it did not resolve (also closes two divergences
the new matrix found: malformed-string+marker and non-string addressString were
saved as HR[0]).
One table-driven test (ModbusAddressAuthorityAgreementTests) runs 15 persisted
shapes through driver, deploy gate, model load/save/Validate and the real CSV
export->import under all four families; breaking the CSV export or reverting
the model to the marker rule fails it.
Minors: m1 CSV address cells keep the string+marker while it still describes
them (lossless unchanged round trip), drop it when contradicted, and the review
grid reports the drop; m2 the pre-lane test uses the real export residual; m3
unmarked string-only + typed-cell case added; m4 stale docs/summary and the
unused factory parameter removed.
