## Summary
- standardize Microsoft provider connections around explicit platform vs dedicated identity modes
- centralize admin-consent URL and runtime identity resolution so platform flows no longer fall back to tenant-local credentials
- add migration classification, richer consent and verification state handling, dedicated override management, and focused regression coverage
## Validation
- focused repo test coverage was added across provider identity, onboarding, audit, policy, guard, and migration flows
- latest explicit passing run in the workspace: `vendor/bin/sail artisan test --compact tests/Feature/AdminConsentCallbackTest.php tests/Feature/Audit/ProviderConnectionConsentAuditTest.php`
## Notes
- branch includes the full Spec 137 artifact set under `specs/137-platform-provider-identity/`
- target base branch: `dev`
