No functional defects found. One Low/Open record-only finding: Inspect()
double-parses its TagConfig blob (once directly, once via TryReadTagConfig)
by deliberate design of the module's single-authority split — not pursued
as a fix since it is deploy-time-only (not a hot path) and widening
TryReadTagConfig's signature to avoid it touches consumers outside this
module (Driver.Calculation, AdminUI).
