…BB-80) The Insights tab was locked to the viewport (overflow-hidden throughout), so the Session-flow Sankey shared a fixed height with the Findings rail (up to 42%) plus the header/live/health strips. On common laptop heights the Sankey collapsed to a ~160px sliver and its many themes could only be reached by dragging a cramped inner scroll — you couldn't scroll down to see or interact with the whole diagram. Add an opt-in bodyLayout="scroll" to InsightsWorkbench: the body grows to its natural height and the owning container (the swarm run-detail Insights tab) owns the one scrollbar. In this mode the Sankey renders at full content height (its existing non-fillHeight path, already used by the scenario usage panel), the topic map gets a definite height, and Findings caps at a fixed height instead of a viewport share. User Testing keeps the default "fill" layout, which it relies on inside its absolute-inset container. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Walkthrough
Merge Risk: 🟡 Moderate · up to The scroll-layout change can leave the topic map intercepting ordinary wheel events when data arrives after the initial render, preventing expected scrolling in that panel. This is a bounded but concrete UX correctness issue, so merge should wait for the listener lifecycle fix or explicit owner acceptance. Thanks for using CodeRabbit!

Resolve Gabriel's review findings on the swarm Insights page-scroll: - Wheel-scroll trap (#1): the topic map no longer swallows a bare wheel in scroll layout. New TopicMapPanel `cooperativeWheelZoom` blocks a plain wheel in the capture phase so the page scrolls; zoom stays on Ctrl/Cmd+ wheel or trackpad pinch. (The panel has no +/- controls, so disabling wheel-zoom outright would have removed the only zoom affordance.) - Empty/sign-in centering (#2, #7): swarm-run-detail's scroll wrapper is now a `flex min-h-full flex-col`, and the workbench empty branch takes `min-h-full flex-1` in scroll layout, so the empty message centers again. - Test (#3): assert bodyLayout -> Sankey fillHeight in InsightsWorkbench. - Sticky header (#4): the Sankey header (freshness chip, view toggle, tuning) sticks in scroll layout so it stays reachable on a tall diagram. - Inset (#5): scroll-layout Sankey bleeds to its padded container (px-0) and drops the leftover card border-b; loading/empty states aligned too. - Magic number (#6): topic map height h-[36rem] -> h-[min(36rem,70vh)]. - Trivia (#7): drop the no-op min-h-0 in the scroll branch; replace the maxHeightClass string prop with fillBody so the cap lives with the rail.

Re-run the wheel listener when the graph wrapper mounts.
When the initial render has no snapshot, graphWrapRef.current is null. A later snapshot mounts the wrapper without changing cooperativeWheelZoom, so the effect does not run again. Bare wheel events then reach d3-zoom. Track the wrapper element in reactive state or use a callback ref. Add regression tests for delayed loading and cleanup.

What & why
Kestral BB-80 — Swarm UX: can't scroll down to see the full Sankey / cluster viz.
The Swarm → Insights tab was locked to the viewport (
overflow-hiddenat every level, no page scroll). The Session-flow Sankey therefore shared a fixed height with the Findings rail (up to 42%) plus the header / live / launch-health strips. On common laptop heights the Sankey collapsed to a ~160px sliver over a 420px+ diagram — technically an inner scrollbar, but cramped, easy to miss, and hard to interact with. You couldn't scroll down to see the whole diagram.Change
Add an opt-in
bodyLayout="scroll"to the sharedInsightsWorkbench:overflow-y-auto) becomes the scroller — so the tall Sankey is reachable by scrolling. To be precise: it's the tab body that scrolls, not the whole page (the tabs and the live / launch-health strips stay fixed above it), and it's one scrollbar for the diagram — the Findings rail (max-h-[26rem]), the topic map's session aside, and the drill-down panel each keep their own internal scroller by design.fillHeightpath, already used by the scenario usage panel — so the whole diagram is reachable at any theme count, no cramped inner scroll.filllayout, which it relies on inside itsabsolute inset-0container.Review follow-up (Gabriel Olarte)

InsightsWorkbench(incl. the newbodyLayoutassertions),SessionFlowSankey,TopicMapPanel, andSwarmssuites pass.Reviewer note
A visual pass in the running app against a clustered swarm is the remaining check — the mechanism is validated but I couldn't render it against live Convex data. Cooperative-gesture zoom (Ctrl/⌘+wheel or pinch) is not discoverable without a hint yet; flagging in case we want a transient overlay later.

Summary by cubic
Makes the Swarm Insights tab page-scroll so the full Session‑flow Sankey is reachable, addressing Linear BB‑80. Previously the tab was viewport‑locked with an inner Sankey scrollbar; now the page owns a single scrollbar, and the Sankey renders at natural height.
InsightsWorkbench: addsbodyLayoutprop (default"fill"). In"scroll"the body grows naturally; passesfillHeight={false}toSessionFlowSankey; givesTopicMapPanela definite height (h-[36rem]); caps Findings atmax-h-[26rem]instead of a viewport share.SwarmRunDetail: wraps the Insights container withoverflow-y-autoand setsbodyLayout="scroll"onInsightsWorkbench.User Testingcontinues using the default"fill"layout. To adopt scroll elsewhere, wrap the owner container inoverflow-y-autoand passbodyLayout="scroll".Written for commit 11d8fc3. Summary will update on new commits.
