An output only reaches a parent @binding when the component calls output.<name>(). Two separate faults meant most of the library never got there, and both failed silently at each end. HTML lowercases attribute names, so a parent's @sizeChange registered under "sizechange" while the component emitted "sizeChange". The lookup missed, fell through to a DOM dispatch, and the binding was never invoked. That made all 17 camelCase outputs undeliverable -- DataTable.pageChange and .rowClick, Map.markerClick, ChatBubble.messageClick, LayoutSplitter.sizeChange and the rest. invokeComponentOutput now falls back to a case-insensitive lookup, and a csr test fails without it. Separately, 18 components dispatched hand-built CustomEvents rather than calling output.*. A bubbling event on the component's own root never reaches a binding, because parent handlers live in a registry only the output proxy reads. Card, Footer, Breadcrumb, Accordion, alert, Badge, AnnouncementBar, AvatarGroup, ToggleCount and InputNumber now emit properly; Marquee, Map, Timeline, List and SearchBox additionally declare the outputs they were already firing. Dispatches on window are left alone -- that is how Toaster, Modal and DataTable signal across component boundaries. Verified in a browser both ways before and after: an AnnouncementBar dispatching its own bubbling "dismiss" never reached a page-level @dismiss, and reached it immediately once it called output.dismiss(). This corrects the audit, which called the LayoutSplitter failure "narrow and unexplained" and read 32 dead outputs as 16 components needing a rebuild. "Outputs work elsewhere" was an assumption; the components that worked happened to use lowercase names and output.*. The dead-output ratchet drops from 32 to 22, and a new test forbids the raw-CustomEvent pattern outright. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
