premortem▌

Identify failure modes before they occur by systematically questioning plans, designs, and implementations. Based on Gary Klein's technique, popularized by Shreyas Doshi (Stripe).

### premortem - Run a premortem on a plan, launch, migration, or change before it ships. - Assume it already failed, list the most likely reasons, rank them by likelihood and cost, and turn the top risks into checks, guards, or a rollback plan. - Use when the user says "premortem", "what could go wrong", "stress test this plan", "is this safe to ship", or before a launch, a data migration, a pricing change, a big refactor, or anything costly to undo.
