The same AST sweep over specs found fixtures maintained in parallel across suites that have no reason to know about each other. Twenty-one specs each mounted useMessageStream themselves and ten of the harnesses were byte-identical; twenty now take renderMessageStream, with overrides for the seams that genuinely vary. The SessionInfo builder was spelled out field-by-field in seven specs, so a new backend field broke seven files instead of one. Twenty specs carried their own inert ResizeObserver and eleven repeated the animation-frame, CSS.escape, scrollTo and WAAPI stubs the transcript needs to mount at all — split by scope into src/test/jsdom for what any component might need and the assistant-ui folder's own kit for the transcript. Plus the window-state bridge, deferred, the external-store thread runtime, the manual createRoot harness, and the per-folder caret, env-var, provider and session fixtures. Left alone on purpose: the store suites' makePrimary, where the vi.mock harness around it is the actual duplication and cannot be hoisted out of a hoisted factory; electron's deferred, where reaching into src/ from the main process would invert the layering for eight lines; and the two suites that compose another hook alongside the stream.
