|---|---|---|---|
Purposedifferent | An ADR permanently records an architecture decision with context, trade-offs, and consequence. It creates continuity for later changes because the decision path stays traceable. | When demand only needs to be roughly verified, it tests interest with minimal effort. It measures whether people would take a next step at all. | The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. |
