Flowchart: Complete User Installation Flow
This flowchart illustrates the end-to-end process when a user subscribes to a publisher and installs content, showing how all architectural layers work together with the subscription system.
End-to-End Data Flow Analysis:
| Phase | Input Data | Processing Method | Output Data | Key Transformation |
|---|---|---|---|---|
| Subscription | genhub:// URL | Protocol handler + definition fetch | Subscribed publisher | URL → Publisher registration |
| Discovery | Publisher selection | Catalog fetch + parsing | ContentSearchResult collection | Catalog JSON → Structured results |
| Resolution | Content selection | Release fetch + parsing | ContentManifest | Lightweight data → Installation plan |
| Acquisition | Artifact URLs | Download + hash verification + CAS storage | Files in CAS | Remote artifacts → Local deduplicated storage |
| Assembly | File references + strategy | CAS file mapping + workspace creation | Ready workspace | CAS references → Functional environment |
| Launch | Workspace path + config | Process creation + monitoring | Running game process | Static files → Active game session |
Real-World Implementation Example:
- Subscription: User clicks genhub://subscribe link → Definition fetch → Publisher added to sidebar
- Discovery: User selects publisher → Catalog fetch → Content list displayed
- Resolution: User clicks Install → Release details fetched → Manifest with artifact URLs created
- Acquisition: Artifacts downloaded (150MB) → SHA256 verified → Files stored in CAS by hash
- Assembly: Strategy selection → Files symlinked/copied from CAS → Workspace validated
- Launch: Process execution → Isolated environment → Content-enabled gameplay experience
