Fix #3 of this PR cached a leafId -> tabId map per layouts record and revalidated it by comparing every root reference on every read. It was the only mutable cross-call state in the change, the only piece carrying a staleness invariant, and it had already needed one follow-up fix (1c23c544) after a layout-identity key turned out to be blind to `persistPtyBinding`'s in-place `layout.root` graft. The index was never what produced the measured win. After fix #1 moves the freshness gate first, the reporter's replay never calls `findTerminalTabIdForLeaf` at all — every stored expired lease is older than the 30 s recovery grace, so the entire 24.9 ms -> 0.9 ms comes from fixes #1 and #2, both of which are unchanged. `findTerminalTabIdForLeaf` is now an allocation-free scan over the existing `layoutContainsLeafId`, which short-circuits on the first matching leaf instead of materialising a Set per tab. Same answers, same first-tab-in-record-order semantics, no revalidation key, nothing for a writer to invalidate. Re-measured on the same 414-worktree / 801-tab / 137-lease replay (process.cpuUsage deltas, median of 3; wall clock is useless on this box): scenario main index scan all leases stale (replay) 24.86 0.87 0.88 ms/publish one lease inside the grace 24.31 1.08 1.04 ms/publish all 137 inside the grace 18.04 3.71 4.31 ms/publish The measured win is unchanged. Only the synthetic worst case — every one of 137 leases expiring inside the same 30 s window — pays for the cache's absence, and even there the two ranges overlap because the index's own revalidation is O(tabs) per lookup. Removes 208 net lines. `terminal-leaf-tab-resolution.test.ts` keeps the parity cases and adds the guard the cache needed: a subtree replaced in place after an earlier read must be visible to the next one. That test fails against the index.
