Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to iOS recovery now reasserts the existing event subscription after a transient liveness-probe timeout instead of immediately replacing the session, while connection handoff no longer waits for diagnostic stream teardown. The repair test does not yet prove that the retry was acknowledged or resumed event delivery, leaving a bounded risk that this recovery path could appear successful without restoring subscriptions.

3900-3901: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winConsider a shared generation-guard helper.
loadPairedMacs()andloadRegistryDevices()each repeat the inline patternguard loadGeneration == <token>, await isScopeCurrent(scope) else { return }three times. This file already has this exact concept abstracted for other generations (isCurrentPairingAttempt(_:),isCurrentConnectionAttempt(_:),isCurrentMacSwitchAttempt(_:)). Extract a similar small predicate for each new token (for exampleisCurrentPairedMacLoad(_:scope:)andisCurrentRegistryDevicesLoad(_:scope:)) so a future edit cannot drop the scope check at one of the six call sites without noticing the inconsistency with the established convention.♻️ Example helper extraction
+ private func isCurrentPairedMacLoad( + _ generation: UInt64, + scope: MobileShellScopeSnapshot + ) async -> Bool { + generation == pairedMacLoadGeneration && (await isScopeCurrent(scope)) + } + public func loadPairedMacs() async { ... - guard loadGeneration == pairedMacLoadGeneration, - await isScopeCurrent(scope) else { + guard await isCurrentPairedMacLoad(loadGeneration, scope: scope) else { return }Also applies to: 3913-3913, 3928-3936, 3956-3957, 3971-3972

Summary
Evidence
The INTERNAL phone journal shows a 3.624s physical transport drain before the replacement dial begins. The path-event observer was awaited after the session had already closed. Successful replacement transport setup then took 1.147s, with route discovery at 365ms and the direct leg at 68ms. Separate failed dials spent 6.3–7.5s in retry timeouts.
The phone journal also shows three overlapping registry loads and results oscillating from two devices to one and then zero. The Computers sheet is sourced from paired Macs; registry data enriches those rows and cannot restore a missing persisted pairing.
