Post-Release & Learning

Finding out what actually happened.

The largest section in the corpus, because the chain has the most to learn here. The first 48 hours are watched; the prediction is checked; bugs are classified by chain level; incidents are contained then diagnosed; the model is updated so the learning survives the conversation.

Primary owners: PO, Tech Lead. Primary volume: V — After We Build.
