 ## Unreleased
 
+- Fixed legacy bot startup and round-transition lifecycle races by attaching peers after game setup and containing stale callback tick errors during shutdown.
 - Added two-engine conformance evidence for pending scan delivery, turn-boundary timing, custom-event removal, skipped turns, handler exceptions, and official melee-participant-count scans.
 - Preserved classic handler-exception reporting by surfacing legacy callback failures at the bridge boundary while retaining Tank Royale's event queue.
 - Added grouped team-robot staging and two-engine conformance evidence for team membership, teammate messages, directed-recipient isolation, droid no-scan behavior, and arbitrary serializable message payloads.

 The implementation will first establish the exact ordering at `setPeer`, `GameStarted`, `RoundStarted`, first tick, and nested event callbacks. It will then update the smallest owning layer, add focused tests, and rerun the affected conformance probes and sweep checkpoint.
 
 No permanent architecture or criterion meaning is intended to change; the goal is to restore the existing classic-parity behavior under the bridge.

+This change closes the actionable lifecycle repairs found in the partial sweep. The full M-006 baseline remains open because the user-directed stop left the sweep resumable rather than complete.
