* Descriptor-driven column tables. A descriptor array defines table order;
* callers provide a separate index array when JSON requires a different
* subset or ordering. The getter lets one engine serve different row types
* while keeping derived values (rates, utilization, and so on) with the
* table-specific code. A column is active when all its required_flags are
* present in the active_flags supplied by the caller; the emitter assigns no
* domain-specific meaning to those bits.
