Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟠 High · up to The leave-cancellation change is not merge-ready because some join and reconnect paths can still reuse stale session state, leak connections, or restart joining after the user has left; the affected test code also currently prevents TypeScript compilation.

coordinatorJoin.resolve(...) passes a response to a parameterless resolver, which produces a TypeScript error. Use JoinCallResponse as the deferred type.

💡 Overview
leave()now cancels a join completely: no further retries, no coordinator response applied, no peer connections or reporters created, and reconnect callers skip post-join work on a left call.📝 Implementation notes
Reuses the existing supersededByLeave pattern.
Now also checked in the retry loop and at each await in doJoin, and surfaced as a 'joined' | 'superseded' result for reconnect callers.
