I have spent too many nights debugging storage problems that were not outages... just unresolved states.
Something was probably available. A retriever thought it was. An indexer said it was. Nobody could say when that stopped being true.
Walrus cuts that middle zone out. Availability is coordinated once on Walrus, enforced at the protocol... and carried forward. No retroactive interpretation. No "maybe the indexer missed it".
When ambiguity is removed at the storage layer, teams stop building workflows around excuses.
That is not reliability.
That is actually aging without drift.
