Needs by door: event feed
3 needs. How it works: 5. Outside apps and the event feed. All needs.
| The customer asks | Verdict | Door |
|---|---|---|

| Check a limit (an item's maximum discount, say) against the ceiling only when someone sets or changes it, not on every edit of the record | Ready, with limits (3) | Event feed |
| Our app gets its own queue of what changed, with business labels | Ready, with limits (1) | Event feed |
