Rebuilding it should have been a ten-minute <code>terraform apply</code>. It took five days.</p> <p>Not because the recovery itself was complicated, but because three assumptions I had never actually tested turned out to be wrong at the same time — and two of them failed <em>silently</em>. The cluster came back looking healthy while quietly missing half its telemetry. This is what broke, why each assumption held right up until it didn&rsquo;t, and what I changed so the same sequence can&rsquo;t repeat.</p>
