001 keyValue is read string-only while whereValue accepts any scalar, and Inspect
then reports a numerically-authored key as ABSENT — an authoring surface
disagreeing with the runtime about why (the #549 class);
002 cross-module: TagConfigJson's strict enum read rests on Enum.TryParse, which
accepts a numeric string, so "type":"99" is Valid and an undefined
DriverDataType reaches the address space. Fix belongs in Core.Abstractions.
The accept-gate-first Inspect and the strict enum reads are otherwise exactly the
#549-#559 arc's rules, implemented structurally.
