JIRA: https://sendbird.atlassian.net/browse/CPLAT-10756 The References preview still had three symptoms — stuck on "Resolving…", lag, and CPU spikes. Root cause was structural: the extract/resolve was never dispatched from a real Update path, so it leaned on the View render path (which discards cmds) plus a tick flush. - setSessPreviewMode returned no cmd. Entering References mode therefore dispatched nothing; the extract only ran when the View render path happened to call updateSessionRefsPreview (cmd discarded) and handleTick later flushed a pending slot. That added up-to-3s latency and, if navigation intervened, left the pane stuck forever. Fixed: setSessPreviewMode now returns updateSessionPreview()'s cmd, and every caller dispatches it. - The View render path (renderSessionSplit) called updateSessionPreview for refs mode every frame, mutating refsInFlight as a side effect while discarding the returned extract cmd — the exact shape that stranded a session on "Resolving…". Fixed: exclude refs (like live) from the View path; it is initialized from Update paths only, and re-rendered on resize via resizeAll (which can dispatch). - updateSessionRefsPreview allocated a fresh viewport.New on every call. Fixed: only reallocate when the pane dimensions actually change. Removes the sessRefsPending map + handleTick flush crutch (no longer needed now that entry/navigation/resize all dispatch the cmd directly). Replaces the pending-flush test with TestSetRefsPreviewModeDispatchesExtract, which asserts entering refs mode returns a cmd that extracts the selected session.

…root cause) JIRA: https://sendbird.atlassian.net/browse/CPLAT-10756 The References preview kept getting stuck on "Resolving…" no matter where the extract/resolve was dispatched from. Five prior fixes moved the dispatch around (#57/#58/#60/#61 + the on-entry commit) because they read the symptom as a missing dispatch. The dispatch was fine — a.sessions WAS being updated. The render path was reading the wrong copy. Root cause is duplicated state with the reader pointed at the stale half: - refsExtractedMsg / refStatusMsg update a.sessions[i].Refs (the source of truth) but do NOT rebuild the session list. - updateSessionRefsPreview renders from selectedSession(), which returns the list widget's sessionItem.sess — a copy snapshotted at the last rebuildSessionList. That copy's Refs/RefsResolved never update, so the preview sees len(refs)==0 && HasRefs && !RefsResolved forever → "Resolving…", while refsInFlight stays armed and blocks re-extract. Every other preview mode (memory/tasks/workflows) stores results in an App-level cache keyed by session ID, so they were immune; refs alone stored state inside the session slice. Fixes: - updateSessionRefsPreview now re-reads the authoritative session from a.sessions (new sessionByIDFromStore) instead of trusting the passed-in list copy. Covers both the async-handler and navigation paths. - carryOverRefState preserves resolved/mid-flight Refs across a full rescan (manual refresh, new-session autorefresh), which replaced a.sessions with a freshly-scanned slice that has HasRefs but empty Refs — blanking resolved refs and, mid-resolve, stranding on a bogus "No resolvable references". Transcript-grew sessions keep cached refs but clear RefsResolved for one re-resolve; in-flight sessions are left for their pass to finish. Tests: TestRefsExtractedReflectedInPreview (fails before the read-from-store fix), TestRefsSurviveRescan, TestCarryOverRefStateReresolvesOnTranscriptGrowth, TestCarryOverRefStateKeepsMidFlight.
JIRA: https://sendbird.atlassian.net/browse/CPLAT-10756 Previously the open-PR/Jira badge only appeared after the user opened a session's References preview, because ref status was resolved on demand for the open preview only. Sessions you never previewed showed no badge even when they had open PRs. Now badges fill in asynchronously for the sessions currently ON SCREEN: - resolveVisibleRefsCmd extracts refs for the visible page slice (Paginator.GetSliceBounds) whose links aren't resolved yet, dispatched from handleTick and the navigation debounce. refsInFlight dedups so a row visible across many ticks is worked once. - syncSessionRefsToList copies resolved state from a.sessions (source of truth) into the list-widget row copy so OpenRefCounts — and thus the badge — updates live, without a full rebuildSessionList that would reset scroll/cursor. - refStatusMsg now calls syncSessionRefsToList so the badge fills in whether or not the References preview is open. Deliberately scoped to the visible page, NOT the fleet. A tick-driven sweep across every HasRefs session is exactly what pegged CPU for minutes (each `gh pr view` ~1.6s, hundreds of them) and was removed in #60. Bounding work to what the user can see keeps the fan-out tiny: extract is a ~10ms offline scan and the follow-on status resolve is already capped at 4 concurrent. Tests: TestResolveVisibleRefsCmdOnlyVisibleUnresolved (scope + dedup), TestSyncSessionRefsToListUpdatesBadge (badge reflects resolved state).

Problem
The References preview kept getting stuck on "Resolving…" no matter where the extract/resolve was dispatched from. Five prior fixes (#57/#58/#60/#61 +
dispatch on entry) moved the dispatch around because they read the symptom as a missing dispatch.The real root cause (state ownership)
The dispatch was fine all along —
a.sessionswas being updated. The render path was reading the wrong copy.State was duplicated, with the reader pointed at the stale half:
refsExtractedMsg/refStatusMsgupdatea.sessions[i].Refs(the source of truth) but do not rebuild the session list.updateSessionRefsPreviewrendered fromselectedSession(), which returns the list widget'ssessionItem.sess— a copy snapshotted at the lastrebuildSessionList. That copy'sRefs/RefsResolvednever update, so the preview sawlen(refs)==0 && HasRefs && !RefsResolvedforever → "Resolving…", whilerefsInFlightstayed armed and blocked any re-extract.Every other preview mode (memory/tasks/workflows) stores results in an App-level cache keyed by session ID, so they were immune. Refs alone stored state inside the session slice — which is also wiped by a full rescan.
Fix
updateSessionRefsPreviewnow re-reads the authoritative session froma.sessions(newsessionByIDFromStore) instead of trusting the passed-in list copy. Covers the async-handler, navigation, and resize paths in one place.carryOverRefStatepreserves resolved/mid-flightRefsacross a full rescan (manual refresh, new-session autorefresh), which replaceda.sessionswith a freshly-scanned slice that hasHasRefsbut emptyRefs— blanking resolved refs and, mid-resolve, stranding on a bogus "No resolvable references". Transcript-grew sessions keep cached refs but clearRefsResolvedfor one re-resolve; in-flight sessions are left for their pass to finish.The earlier commit on this branch (
dispatch ref extract on entry, keep View pure) is kept — dispatching from a real Update path and keeping View pure are still correct — but they were necessary, not sufficient.Async open-PR/Jira badges (follow-up commit)
Previously the open-PR/Jira badge only appeared after opening a session's References preview, since status resolved on demand for the open preview only. Sessions you never previewed showed no badge even with open PRs.
Now badges fill in asynchronously for the sessions currently on screen:
resolveVisibleRefsCmdextracts refs for the visible page slice (Paginator.GetSliceBounds) whose links aren't resolved yet, dispatched fromhandleTickand the navigation debounce.refsInFlightdedups so a row visible across many ticks is worked once.syncSessionRefsToListcopies resolved state froma.sessionsinto the list-widget row copy soOpenRefCounts— and thus the badge — updates live, without a fullrebuildSessionList(which would reset scroll/cursor).refStatusMsgnow callssyncSessionRefsToListso the badge fills in whether or not the References preview is open.Deliberately scoped to the visible page, NOT the fleet. A tick-driven sweep across every
HasRefssession is exactly what pegged CPU for minutes (eachgh pr view~1.6s, hundreds of them) and was removed in #60. Bounding work to what the user can see keeps the fan-out tiny: extract is a ~10ms offline scan and the follow-on status resolve is already capped at 4 concurrent.Testing
