عرض عملي: تقسيم عنقود من ثلاث عقد ومراقبة ما يختاره

خطوة بخطوة

1. Start a three-node cluster in containers (verify version before recording) and write a key.
2. Isolate one node and show writes still commit on the majority side.
3. Read from the isolated node and show it refuses or returns stale data depending on settings.
4. Planned mistake: isolate two nodes and expect writes to continue; fix by explaining that no majority means no commits.
5. Heal the partition and show the follower catching up.
