Identifies a keyed collection descriptor without starting its source.

Recognizes a descriptor before a target chooses its keyed rendering path. This guard does not subscribe to the collection or validate its current keys; key uniqueness is checked when the target receives an array.

A collection source, stable key function, and per-item view supplied to a renderer. Describing the collection acquires nothing; the active target owns subscription and child lifetimes.

The DOM target retains each key’s subject and scope across moves. The HTML target consumes an initial collection for finite response output. Construct descriptors with many rather than assembling this protocol by hand.

Efficiently renders a reactive list of items by using keys to minimize DOM operations and maintain component state.

many returns a renderer descriptor rather than an Fx. The active renderer consumes its source directly and can therefore retain keyed entries without flattening each child back through a generic collection stream.

Produces the closing hydration marker for a keyed-list item.
