# Sprint 21: Interactions API Integration

> Migrating the Python Content Factory to the GA Gemini Interactions API for background compute offloading.

# Sprint 21: Interactions API Integration & Compute Optimization

With the core features and telemetry pipelines locked, Sprint 21 focused on infrastructure optimization. By migrating the Python Content Factory to the General Availability (GA) Gemini Interactions API, we successfully offloaded the heavy 3D ideological vector reasoning to Google's background infrastructure.

## 🗺 Sprint 21 Roadmap

### \[x] Phase 1: Dependency & Environment Upgrade

* Deprecated the legacy `google-generativeai` SDK.
* Upgraded to the production-ready `google-genai>=2.3.0` SDK.
* Transitioned to implicit, zero-trust credential resolution via `genai.Client()`.

### \[x] Phase 2: Content Factory Refactoring

* Replaced blocking generation loops with `client.aio.interactions.create` using `background=True`.
* Integrated FastAPI `BackgroundTasks` to instantly return an `HTTP 202 Accepted` to the Cloud Scheduler metronome, completely eliminating 504 Gateway Timeouts during heavy RSS ingestion.
* Enforced strict output validation using Pydantic schemas via the API's `response_format` parameter.

### \[x] Phase 3: Validation & Deployment

* Executed local `dev_mode` prefab RSS fixtures to confirm schema parity and polling architecture.
* Successfully deployed the optimized container to Cloud Run via the automated Google Cloud Build CI/CD pipeline.
