R2-11 Phase C. All six equipment-tag parsers (Modbus/S7/AbCip/AbLegacy/
TwinCAT/Focas) now read enum fields via the new TagConfigJson.TryReadEnumStrict:
absent -> fallback, valid -> parsed, present-but-invalid (typo) -> TryParse
returns false -> EquipmentTagRefResolver.TryResolve false -> driver surfaces
BadNodeIdUnknown, instead of the old lenient path that silently defaulted a
typo to a wrong-width Good.
Modbus flips all three enum fields (region/dataType/byteOrder); the other five
flip dataType. The deploy-time Deployment:TagConfigValidationMode=Error gate is
unchanged and remains the operator pre-flight.
Coverage:
- Six *EquipmentTagParserStrictnessTests inverted from Freeze_typo_* (lenient)
to Typo_*_rejects_the_tag + Valid_*_still_parses.
- TagConfigJsonTests.TryReadEnumStrict_rejects_only_invalid matrix.
- Driver-level end-to-end proof:
AbCipEquipmentTagTests.Driver_read_of_a_typod_dataType_ref_surfaces_BadNodeIdUnknown
drives the real AbCipDriver.ReadAsync through resolve->status.
Golden parity corpus has no typo'd enums, so the flip is a no-op there.
Full solution builds clean; all six driver suites + core + parity + gate green.
Adds <summary>/<param>/<returns>/<inheritdoc> where missing and removes
project bookkeeping IDs (task/tracking refs) from shipped code comments,
so the docs read cleanly and CommentChecker is quiet except for known
false positives (PLC/protocol terms, event/IEqualityComparer inheritdoc).
Doc/comment-only; no logic changed; solution builds clean.
First review at 7286d320. -001 (Low) fixed: ArrayLength=1 doc corrected (it is a 1-element
array node, not scalar). -002/-003/-004 (parser edge doc, dead MaxTagBytes, ForFamily
fallback) Open.
Move AbLegacyDriverOptions, AbLegacyDataType enum, and
AbLegacyPlcFamilyProfile (including AbLegacyPlcFamily enum) to a new
Driver.AbLegacy.Contracts sibling project. All three files are zero-dep
after splitting AbLegacyDataTypeExtensions (which uses DriverDataType
from Core.Abstractions) into a new file that stays in the runtime driver.
Drop the doc-comment <see cref="AbLegacyAddress.TryParse"/> reference and
replace with <c>AbLegacyAddress.TryParse</c> per the approved decision.
The PlcFamilies using directive is retained in the contracts project since
both namespaces live there.
The runtime Driver.AbLegacy project gains a ProjectReference to .Contracts;
the .slnx is updated accordingly.
