Laravel helps structure new code. It does not explain years of inherited decisions.
A mature Laravel codebase can be conventionally structured and still carry operational risk through model events, hidden scopes, queue behavior, package assumptions, database views, duplicated business logic or deployment steps that only one person remembers.
The takeover starts by locating those application-specific contracts before trying to make the code “cleaner.”
Laravel-specific takeover work can include
- Framework version, PHP version and dependency compatibility
- Eloquent relationships, scopes, observers and model events
- N+1 queries, broad hydration and expensive aggregate paths
- Jobs, queues, failed jobs, workers and scheduler behavior
- Policies, guards, middleware and authorization boundaries
- Service container bindings and application-level abstractions
- Storage, mail, cache and external service configuration
- Laravel upgrade planning and staged execution
