In Figma's data a component set holds one text property per variant (plus leftovers of deleted variants), and an instance lists only the ones its current variant's layers read (measured in Figma's web app). FigCraft listed every definition on every instance, and wrapped a long property name inside an 84 x 20 box so its lines painted over the rows around it.
- components::instance_prop_list: prop_list keeping slots and the properties a layer of the component references (a nested instance counts, its layers and slot content are not entered). component.properties and the Properties panel use it for instances; sets, components and variants still list every definition.
- prop_label cuts the name to one line with an ellipsis and shows the full name on hover.
- Tests: an_instance_lists_only_the_properties_its_variant_uses, a_long_property_name_stays_on_one_line, and the pin a_set_keeps_each_named_text_definition_and_layers_read_their_own. Two tests and one setup that listed an unbound boolean on an instance now bind it to a layer.
- docs/components-parity.md: the properties row, header and revision history.

component.createSet now refuses a selection where one layer is inside another, as component.combineVariants does, before changing the document (the nested layer was silently dropped from the set). Adds the component.createSet label to the 22 locale catalogs that list component.createMultiple.

The third entry of the menu several selected layers get: each layer becomes a component and they are wrapped in a component set in place, 20 px around, named as Figma names them (measured): "Property 1=<layer name>" in left-to-right order, prop=value names kept, and layers that all share a name give a set of that name with "Default" variants. Engine tests cover the three measured cases, geometry, selection, one undo and the refusal of instances; the UI test checks the three menu entries in order and that the third makes one set.

* M3: team library analytics count detached instances
Detaching an instance of a library component counts it in the file (libraries.detached, saved with it, capped). The background library check reports the counts after its fetch (ReportDetached); the server keeps them per file beside the file's usage report in usage.json (same caps) and answers Detached with them. Show usage and library.usage list detaches per component and per file (detached, detachesKnown). The new request and reply variants are appended, so every older library message keeps its bytes; an older server refuses the new requests, which the app ignores. Gap 10.
* M3: the detach test waits for the instance count too (the two arrive in separate reports)
Properties were listed by name, so a rename moved one. Components now keep prop_order (the names as they were made; a rename keeps the place) and every listing follows it. Make slot opens a name field under the frame's Slot row; Enter makes the slot, Escape cancels, a taken name keeps the field open.
* M2: components can't contain their own instances (#1084)
Edits that would make a component hold an instance of itself, directly, through other components or through another variant of its set, are refused with the loop named. Files holding such a loop open with one instance per loop detached and a note; a rebuild never expands an instance inside a copy of itself, so a loop merged in a live session stops growing.
* M2: a variant may hold a sibling variant's instance; only true loops are refused (#1084)
Each variant counts as its own component: refusals and open-time repairs apply only to a component leading back to itself through instances (an instance-swap value included), so files with nested sibling variants open unchanged. sync_instance_depth is split into match_layers and copy_layers.
