Term	Kind	Topic	What it is
Consumer Liveness Gap Zombie Consumer, Progress Blindness	concept	Competing Consumers	The interval in which a queue consumer is alive by every health signal yet is making no progress, so its share of the work stalls while pool-level metrics stay normal.
Partition Assignment	concept	Competing Consumers	The mapping of partitions to consumer instances that determines parallelism, ordering guarantees and what happens when the consumer set changes.
Visibility Timeout Message Lease, Invisibility Window	concept	Competing Consumers	The period a claimed message is hidden from other consumers - too short and work is duplicated, too long and a crashed worker stalls the item.
