| โ ๏ธ Problem | Without phone-key match health checks, the 4,024-overlap calculation can drift silently as new customers add. |
| ๐ฐ $ at stake | Drift = mis-attribution = re-introduction of ghost-revenue or double-count traps. |
| โ Action unlocked | Run match-health cron weekly. Flag if overlap drops below 4,000 or rises above 4,100. |
