## Summary
- retire remaining legacy tenant-panel runtime assumptions in the Filament admin runtime and route resolution paths
- centralize canonical admin environment context handling for shared surfaces instead of relying on deprecated `tenant` panel behavior
- harden guard coverage so legacy `/admin/t` and `/admin/tenants` route families cannot regress
- update scoped navigation, drillthrough, reference-link, and global-search tests to use the admin panel environment runtime
- add the Spec 304 package under `specs/304-tenant-panel-dead-code-retirement/` and document the rollout in the product ledger
## Test Coverage Updated
- `AdminSharedSurfacePanelParityTest`
- `NoActiveTenantResourceRoutesTest`
- `NoLegacyTenantPanelRuntimeTest`
- `AdminTenantResolverGuardTest`
- `PolicyVersionResolvedReferenceLinksTest`
- `EntraGroupGlobalSearchScopeTest`
- `OperationsDashboardDrillthroughTest`
## Runtime Notes
- remains compliant with Filament v5 on Livewire v4
- no provider registration changes; provider registration location remains `apps/platform/bootstrap/providers.php`
- no new globally searchable resource was introduced; existing scoped search assertions were updated only
- no destructive actions were added or changed
- no asset registration changes; deploy posture for `cd apps/platform && php artisan filament:assets` is unchanged
## Validation
- updated tests and docs/spec artifacts were committed in this branch
- tests were not re-run in this turn

## 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
