* fix(activity): bound Activity portal readiness oscillation (React #185) React error #185 is "Maximum update depth exceeded" -- an unbounded render loop, not setState-after-unmount as the crash reports superficially suggest. Verified in react-dom@19.2.7's production bundle: getRootForUpdatedFiber throws Error(formatProdErrorMessage(185)) when 50 < nestedUpdateCount. That frame is the top of all 14 crash stacks across shipped 1.4.156 / 1.4.158 / 1.4.159. nestedUpdateCount and rootWithNestedUpdates are module-level globals keyed on the ROOT, not on a component. One runaway loop saturates the counter and the throw lands on whichever fiber calls setState next, so SortableTab (terminal.workbench), the Radix Presence/MenuPortal (page.settings) and the sidebar.worktrees button are innocent bystanders with misleading component stacks -- four boundaries, one bug. The driver is Activity's portal readiness pass. When 'ready' is unreachable while 'unavailable' stays reachable, updateReadiness flips loading<->unavailable from inside useLayoutEffect -- React's sync lane, the lane that increments nestedUpdateCount -- so it saturates and throws rather than merely being slow. A prior investigation captured this live on Windows via CDP at 239 renders in 847ms. Bound the oscillation: after ACTIVITY_PORTAL_READINESS_MAX_FLIPS consecutive loading<->unavailable transitions the latch parks on 'unavailable' until a real 'ready' arrives. The latch rewrites only the hook's output, never the DOM probe, so a terminal that churns during a slow attach and then genuinely comes up still releases it. Because the counter is global per root, this also protects every innocent bystander in the app -- most of the user-visible value. Extract reconcileActivityPortalThreads and resolveActivityPortalSwap so the portal loop is testable against the real collaborators. Note the reconciliation keeps its worktree+tab comparison deliberately: Terminal mounts one TerminalPane per (worktree, tab) and routes it by worktree+tab, so staging a same-tab pane would leave the staged slot empty and its readiness stuck on 'loading' forever. Same-tab switches swap in place via isolatedPaneKey instead.
