Quick index for operational failures seen on real Webkernel projects.
| # | Topic | When to read |
|---|---|---|
| 01 | Package manifest / empty bootstrap/cache/packages.php |
Routes or providers missing after composer install |
| 02 | Target class [view] does not exist |
Artisan crashes; often stale provider after package removal |
| 03 | Deny-all config true but panel still open | Filament access control testing |
Rule of thumb: read the root error in the stack trace (first exception), not the last wrapper message.
