Developer Builds Incident-Diagnosis Agent That Retains Only Resolved Outages

A developer has built an open-source incident-diagnosis tool called BlameLess that uses a persistent memory store, called the Hindsight bank, to help diagnose future outages. The system's core design rule is that unresolved incidents exist only in temporary session memory and are discarded on restart, while only resolved incidents with confirmed root causes and fixes are written permanently to the Hindsight bank. When a new incident arrives, the system performs a semantic search over past resolved incidents to suggest a likely root cause and fix, with reasoning driven by accumulated memory rather than the language model alone. A deliberate engineering choice ensures that if writing to the Hindsight bank fails during resolution, the application still returns a success response with a warning, so that a human-verified resolution is never lost due to a storage error. The append-only, no-delete design reflects the developer's view that a confirmed resolution is far harder to recreate than raw log data and therefore must be preserved above all else.
