| 2c34075 | 3 | * |
| 4 | * Called after every successful git push. This is gluecron's intelligence layer: | |
| 5 | * 1. Auto-repair — fix common issues and commit automatically | |
| 6 | * 2. Push analysis — detect breaking changes, security issues | |
| 7 | * 3. Health score — recompute repo health | |
| 8 | * 4. GateTest scan — external security scanning | |
| 9 | * 5. Crontech deploy — auto-deploy on push to main | |
| 10 | * 6. Webhooks — fire registered webhook URLs | |
