//  - Integer types live in the low portion of registers. Upper portions are junk.
//  - Boolean types use the low-order byte of a register. 0=false, 1=true.
//    Upper bytes are junk.

	// Stale and StaleReason remain here *only* for the list command.
	// They are only initialized in preparation for list execution.
	// The regular build determines staleness on the fly during action execution.
