The `runtime:syncWindowGraph` IPC handler is the most expensive thing the main process does: measured on a real session it costs 20.7 ms per call at 0.71 calls/sec, which is 1.47% of wall and ~17% of all main-thread JS. 76% of that sits in one subtree: `getHydrationTargets` -> `hasRuntimeOwnedPtyCandidate` -> `getRecentExpiredSshLease` -> `findTerminalTabIdForLeaf`. Three pieces of pure waste, none of which change an answer: 1. `getRecentExpiredSshLease` evaluated its cheapest and most selective filter LAST. `SSH_PANE_RECOVERY_GRACE_MS` is 30 s, so nearly every stored expired lease fails it — but only after the predicate had already resolved the lease's leaf to its current tab, which is the expensive part. The freshness and reattach-eligibility gates now run first; the predicate is otherwise identical and side-effect free, so the selected lease is unchanged. 2. The sweep ran once per tab. `workspaceSessionWorktreeHasRuntimeOwnedPtyCandidate` asked "does a recent expired lease name THIS tab" for every tab in a worktree, and each ask re-read and re-filtered the whole lease list. It now resolves the worktree's recoverable tab ids once, lazily, so a worktree whose first tab already owns a serve/SSH pty still never sweeps. 3. `findTerminalTabIdForLeaf` allocated a `Set` and walked a whole pane tree per tab to answer one leaf lookup. It now reads a leafId -> tabId index built once per layouts record and reused until a layout object is replaced, which keeps first-tab-wins ordering identical. Measured by replaying a real 414-worktree / 801-tab / 137-lease session: 2.51 ms -> 0.27 ms per publish for this subtree, a 9.3x cut. No user-facing trade-off: same leases selected, same tabs reported recoverable, same SSH pane recovery affordance.
