Patch Changes

• 7e04096: Accordion — Item · Trigger · Indicator · Content

  P5.11, over the legacy ExpansionPanel. The reference implementation calls it accordion and so does this, which is also what the roadmap row now says.

  The height is never measured. The panel is mounted or it is not, and Reanimated's layout transition animates the row between the two — LinearTransition.springify() on the reference implementation's numbers, damping 140 against stiffness 1600. Stiffer than the chevron's 1000 deliberately: a height is a longer distance than a rotation, and at the chevron's stiffness the same damping makes a long panel take almost half a second to settle.

  Measuring it would mean a hidden pass on every open, and a panel whose content grows afterwards — an image loading, a list filling — would be stuck at the height it had when it was measured. The container carries the same transition, because without it the accordion's own height jumps to its new total in one frame while the rows inside it are still animating.

  The variant table is the Card's, token for token. An accordion in default is a card with rows in it, and two containers that look alike but are declared apart drift — the drift showing up as an accordion sitting on a card with a fill one step off it. ghost is the default and is the reference implementation's own: rows separated by hairlines, on whatever page they sit on.

  The separators are the root's, drawn between its children. A row that drew its own would draw one under the last item too, and every accordion would start by hiding it. They come off Children.toArray, which drops nulls, so a conditionally rendered row cannot leave a hairline hanging where nothing is.

  The open state moves to the root. Legacy asked each item whether it was open, which is what made "only one at a time" the caller's problem. One value on the container is what selectionMode needs to mean anything. The whole rule is a pure function with thirteen tests, including the two cases where it returns the value unchanged — a press refused under isCollapsible={false} must not fire onValueChange for a change that did not happen.

  ChevronDownIcon moves from the Select's folder to system/icon and is exported from @xaui/native/system. Two components draw it now, which is §2 bis exactly: promotion at the second use, never by anticipation.

• 7abe5b5: The build cleans dist/ before writing it

  clean: false had been set since the legacy era, with nothing saying why, and against splitting: true it is a bug waiting for the entry list to change.

  Split output names its shared chunks by content hash. A build whose entries changed writes new chunk names and leaves the old ones behind, so dist/ becomes a mix of two builds: an entry from the first still importing chunk-ZF6KIHXH.js, which the second replaced with a different hash and never wrote.

  Metro's report of that is Unable to resolve "@xaui/native/accordion" — it names the component and says nothing about chunks, which sends you looking at the export map, the subpath and the workspace link, all three of which are fine.

  It bites hardest across branches, because turbo restores a cached dist/** over whatever is already there rather than in place of it. Switching from a branch that has a component to one that does not, or back, is enough.
