## Hard don'ts

| NEVER                                  | ALWAYS                                  |
| -------------------------------------- | --------------------------------------- |
| Auto-buy compute units / upgrade plans | Use existing Pro+ allocation            |
| Claim edge from Colab charts           | Cite `kill_verdict` from scorecard JSON |
| Leave GPU runtimes idle                | `colab stop` / disconnect runtime       |
