## Summary
- retire legacy `/admin/t` and active `/admin/tenants` product surfaces in favor of canonical workspace-scoped managed-environment routes
- centralize runtime URL generation through `ManagedEnvironmentLinks` and update intended URL handling to reject legacy tenant paths
- remove dormant tenant panel runtime, rename test helpers to the admin environment context, and add guard coverage for route/helper regressions
## Validation
- targeted Feature guard, workspace, provider connection, required permissions, and Filament test lanes run under Sail
- browser smoke coverage run for provider connection and workspace RBAC environment access flows
- formatting and diff checks completed with Pint and `git diff --check`
## Notes
- Filament remains on v5 with Livewire v4
- provider registration stays in `apps/platform/bootstrap/providers.php`
- retired tenant resource global search is disabled and destructive action confirmation rules remain unchanged
