| description | Design delegated Microsoft Graph and Teams webinar integration for the backend. Use for OBO token exchange, webinar CRUD, registrations and attendance reads, drift handling, and Graph error semantics. |
| argument-hint | Describe the Graph operation, Teams webinar context, delegated scopes or token flow, and any failure or retry concern. |
Canonical owner of Graph endpoints, OBO flow, and webinar lifecycle.
TeamsGraphClient + OboTokenService.| Operation | Flow | Delegated scope |

| Webinar CRUD | OBO | VirtualEvent.ReadWrite |
| Registration reads | OBO | VirtualEvent.ReadWrite |
| Attendance reads | OBO | OnlineMeetingArtifact.Read.All |
| Drift detection | OBO | (delegated) |
No client credentials — all operations require an authenticated user.
Extract user JWT from request → ITokenAcquisition.GetAccessTokenForUserAsync with Graph scopes.
| Code | Class | Action |
|---|---|---|
| 401/403 | Token/permission | Log + surface clearly |
| 404 | Not found | Handle gracefully (drift/delete) |
| 429 | Throttled | Respect Retry-After |
| 5xx | Transient | Exponential backoff retry |
Map Graph response → domain model (e.g. webinar id → teamsWebinarId). Log all ops with correlation id, operation name, result.
For each session in series:
teamsWebinarIdPOST .../publishOn any failure: best-effort rollback (delete created webinars); if rollback fails log + surface partial-failure state; return failure.
GET /solutions/virtualEvents/webinars/{id}/registrationsdelegated-data-sync-pipeline).LastSyncAt on session.Drift cache: 5-minute window.
driftStatus.Design ASP.NET Core minimal API request and response contracts. Use for DTO shapes, route and verb decisions, OpenAPI metadata, and compatibility planning before implementation.
Define focused tests for ASP.NET Core minimal APIs. Use for endpoint branch coverage, contract assertions, regression planning, and choosing the narrowest useful verification command.
Design EF Core schema changes, constraints, and migrations for the backend data model. Use for entity updates, indexes, uniqueness rules, cascade behavior, and migration planning.
Design and implement the delegated Graph sync pipeline from fetch through normalization, upsert, and metrics recompute. Use for user-initiated registrations or attendance sync, idempotency, and atomic recomputation.
Define deployment safeguards, environment protections, and rollback readiness for CI/CD releases. Use when adding or reviewing release jobs, promotion controls, or recovery plans.
Apply email and domain normalization plus session and series metric rules, including W1/W2 warm-account logic and internal-domain exclusion. Use for domain logic changes, recompute behavior, and mandatory unit-test coverage.
