`expiredGenerationByPane` was pruned by one rule: same environment, *different* connection generation. The generation only advances on reconnect, and a tab id is never reissued — so on a connection that never drops, every pane that ever hit the handle-gap deadline left an entry that nothing could ever remove. The module comment claimed the prune kept the map "bounded by the panes parked on the current connection". It did not. Measured directly: 500 park-and-expire cycles on one environment at a fixed generation leave 500 entries, one per closed tab, growing monotonically for as long as the session lives. Sizing, because this should not be mis-attributed to the open OOM report: an entry is a short string plus a number, so 100k tab-opens is roughly 10 MB, and reaching this path at all requires a mirrored pane that a local-only user never touches. It is a genuine unbounded-growth bug and it is not that OOM. The fix adds a second prune rule — drop any verdict whose tab id is no longer a published row — so the bound is live panes plus one. The scan is a Set built once per record, and records only happen on a deadline expiry, never on a frame. Both directions are tested, because over-pruning is its own defect: a verdict dropped while its pane is still live re-parks a wait that had already answered. Also pinned here: waiters and their deadline timers drain to zero (`vi.getTimerCount()`), and the store subscription's lifetime is exactly the waiters' — released early it would strand a parked pane forever. Mutation-tested: dropping the liveness rule fails the churn test 500 vs 1; making the prune unconditional fails the live-verdict test; unsubscribing on any waiter drain fails the subscription test. Carries a note on the sibling module: `hydratedGenerationByWorktree` has the same retention class (pre-existing, bounded by worktrees ever hydrated rather than by tab churn, so a far smaller ceiling) and is deliberately left alone.
