Two skeleton flashes made switching feel clunky: - Every switch: the deferred timeline snapshot lags the live one for a frame or two, and that gap painted the full skeleton to mask the previous channel's rows — a visible skeleton flash on every switch. The gap is a render-pipeline artifact, not a loading state: it now renders plain background (new "blank" body surface). Blank blocks the same behaviors as the skeleton (autoscroll, jumps, unread pill, scrollback), only the visual differs. Cold loads keep the skeleton. - Stale revisits: the loading latch reset on every switch, so re-entering a channel past the messages staleTime refetched on mount with the unsettled skeleton branch active — a skeleton over a fully cached timeline for the whole relay round-trip. Channels that settled once this session now render their cached rows stale-while-revalidate (session registry, reset via resetCommunityState like every other community-scoped singleton). The revisit spec forces staleness by shifting Date.now past the 5-minute window and asserts the skeleton never mounts over cached rows; the switch-gap behavior is covered by the timelineSnapshot unit suite.
