CmxIrohHostRuntime and CmxIrohClientRuntime hand-duplicated one lifecycle. Collapse the duplication into CmxIrohRuntimeLifecycle.swift with no behavior change: - CmxIrohRuntimeLifecyclePhase replaces the two verbatim nested LifecyclePhase enums (typealiases keep call sites and tests working). - CmxIrohRuntimeLifecycleManaging (internal Actor protocol) exposes the shared actor state both runtimes already had, enabling actor-isolated shared helpers. - performSignOutFlow extracts the duplicated performSignOut skeleton (persist + concurrent teardown, supersession guard, quarantine branch, inactive reset); the client passes its extra offline-cache/local deactivation step as a closure. cmxIrohPersistSignOutRevocation replaces the two identical static persist helpers. - swapRelayCoordinator extracts the identical coordinator swap from the two +RelayPolicy private replaceRelayProfile funcs; the public entrypoints and role-specific guards/tails stay on each runtime, with client-only retrySchedule/automaticRefreshEnabled as parameters. - activeRelayReachability extracts the identical hasReachableRelay body from the two +RelayReachability files. CmxIrohTCPFirstActivation was slated for deletion but is live (Sources/Mobile/MobileHostService.swift), so it stays. Net -5 lines; error enums, reconcileConnectivityRevision, admission, endpoint server, peer session, and codecs untouched.

📝 WalkthroughWalkthroughThe PR centralizes lifecycle phases, sign-out processing, relay coordinator replacement, and relay reachability checks in shared infrastructure. Host and client runtimes delegate to these helpers through runtime-specific callbacks and configuration. ChangesRuntime lifecycle consolidation
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to This refactor centralizes runtime lifecycle behavior, but concurrent relay-policy updates could leave relay configuration briefly out of sync, and one new helper does not follow repository structure guidelines. The PR is otherwise mergeable with explicit owner awareness and follow-up on these bounded issues. Possibly related PRs

Move cmxIrohPersistSignOutRevocation off the top level.
This adds an internal top-level free function in a production Sources/ path. The repository guideline forbids new top-level free functions and requires behavior to live on an owning type. The function only needs the outbox, so make it a static method on CmxIrohPendingRevocationOutbox or a private helper in the CmxIrohRuntimeLifecycleManaging extension.
As per coding guidelines: "In production Swift code, avoid ambient global state and behavior: do not add public or internal top-level free functions ... Put state and behavior on a constructable, injectable owning type."

Serialize concurrent relay-policy swaps.
requireCurrent(revision) checks only the lifecycle revision. Concurrent replaceRelayProfile calls can share that revision, allowing an older swap to overwrite managedRelayURLs after a newer coordinator is installed. Add a swap-specific revision or serialize swaps. Moving the assignment before the check is not sufficient.

CmxIrohHostRuntime and CmxIrohClientRuntime carried verbatim copies of the same lifecycle machinery. This moves the shared phase enum, snapshot terminal states, sign-out persistence helper, and the performSignOut skeleton into CmxIrohRuntimeLifecycle.swift behind an internal actor protocol, with typealiases keeping every call site and test unchanged. Net delta is 240 insertions against 245 deletions across 9 files, all inside the package, with no behavior change. Part of the mobile-sync rip-out wave 1.
