## 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

## Summary
- normalize provider-neutral target-scope and identity contracts across provider connection resolution, operation-start gating, verification reporting, and boundary configuration
- align provider connection resource, onboarding, tenant summaries, and operation follow-up on the same shared scope contract while keeping Microsoft-specific profile details in provider-owned metadata
- add Spec 281 artifacts and focused feature/browser coverage for the new provider-scope contract
- move the tenant dashboard context-chip rail into Filament header widgets so the metadata row renders directly under the page subtitle
## Validation

## Notes
- Filament remains on v5 with Livewire v4-compatible surfaces only.
- Provider registration location is unchanged; Laravel 11+ providers stay in `apps/platform/bootstrap/providers.php`.
- `ProviderConnectionResource` remains non-globally-searchable and still exposes View/Edit pages.
- No new asset registration was added; deploy-time `filament:assets` expectations are unchanged.
- No new destructive action path was introduced; existing server authorization and confirmation handling remain in place where applicable.
