Subject: [PATCH] Skip parallel suspension when checkpoint is nil
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The triggering entry in the parallel-suspend path stored
se.Checkpoint into innerCheckpoints unconditionally, while
the sibling loop already guarded otherSE.Checkpoint != nil.
A nil entry would later cause restoreNestedSuspended to
dereference innerCP.AgentName and panic. Apply the same
guard so a malformed SuspendedError falls through to the
regular result-collection path instead of poisoning the
checkpoint map.
