Architecture decisions deserve different amounts of attention because the consequences of getting them wrong are not equal. A naming convention can absorb weeks of debate while a database choice slips through under calendar pressure. The useful questions are simple: what happens if we are wrong, and what will it cost to reverse the decision?

This session puts familiar architecture decisions on the table and asks how much ceremony each one has earned. We look at one-way and two-way doors, then use seams, contract boundaries, staged rollout, and sacrificial components to make expensive choices easier to undo. Lightweight architecture decision records preserve why a choice made sense, while fitness functions warn us when a temporary decision is quietly becoming permanent. Whether you're an architect, lead, or the developer whose pull-request comment just became a design meeting, you'll leave with a two-question risk test, an ADR template with explicit revisit triggers, and a faster route through decisions your team can safely change later.
