 *   Dead                        | failOnDeadUnits
 *   WentLive, local marker      | failOnDeadUnits, or strict where strict promotes warnings
 *   WentLive, pack marker       | never — printed as INFO (the consumer cannot edit it)
 *   IntendedEmpty/Live/Unproven | never (an explicit valve is not a warning; the read gap vetoes on its own)

 * Exit 2 is not this predicate's business: a Coverage-weight gap reaches it
 * through record A, whatever the flags.
