## Summary
- add derived onboarding readiness to the managed tenant onboarding workflow and multi-draft picker
- keep provider-specific permission diagnostics secondary while preserving canonical `Open operation` and existing onboarding action semantics
- add spec-kit artifacts for `240-tenant-onboarding-readiness` and align roadmap/spec-candidate planning notes
- unify the required-permissions empty state copy to English
## Validation
- `cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Feature/RequiredPermissions/RequiredPermissionsEmptyStateTest.php`
- `cd apps/platform && ./vendor/bin/sail bin pint --dirty --format agent`
- browser smoke exercised the onboarding picker, route-bound mismatch readiness state, canonical `Open operation` path, and local fixture cleanup
## Notes
- branch includes the generated spec artifacts under `specs/240-tenant-onboarding-readiness/`
- temporary browser smoke tenants/drafts/runs were cleaned from the local environment after validation
