Postmortem
An incident happened. Understand why, document it properly, and make it harder to repeat. No hand-waving, no minimizing.
Why This Exists
Bad postmortems dismiss ("no actual impact"), deflect ("edge case"), or rush ("wrong command, fixed it, moving on"). These teach nothing.
A good postmortem makes the reader feel the weight of what could have gone wrong, traces the failure to its root, and produces concrete changes. It's a document you'd send to your team lead without embarrassment.
