📋 Decision Context

Question:

What is the complete scope and status of S205 @libs-structural/platform-preview library implementation?

Task: Not specified

🎯 Decision Made

Chosen:

New NX library @libs-structural/platform-preview created with 30+ files: 3 type models, 7 services (BundlerService, BundlerFilesystemService, PreviewServerService, PreviewBridgeService, ComponentTaggingService, InstantPublishService, PreviewContentService), 2 rspack plugins, 2 config files, 1 Service Worker, 4 UI components. Integrated into vitto-studio dock panels (both Visual and Code layouts), wired with StudioInterconnectionService for deep cross-tool context, bridge events model extended with 8 new message types + 4 payload types. 4 preview modes: static (JSON summary), rspack (in-browser WASM compilation), devserver (ng serve iframe), space (live URL). Backend instant deploy endpoint added. BLOCKER: rspack compilation cannot work until the generation pipeline (S204) produces clean-compiling Angular code — current generated output has bugs (override without base class, unresolved @libs-core/security imports).

Options Considered:

1. Complete the preview end-to-end by fixing the generated platform output
2. Stop at infrastructure and fix generation pipeline separately
3. Skip rspack, use only devserver mode with ng serve

💭 Reasoning

The full preview infrastructure is built and compiles cleanly within gspace1. The Live Preview tab renders in vitto-studio (confirmed via screenshot). Static mode works and shows space data. The rspack compilation pipeline (VFS→memfs→compile→SW→iframe) is wired but blocked on the generated code quality. The generation pipeline bugs (override without base class, unresolved @libs-core paths) are root-cause issues in backend-vitto-api's code generation templates — fixing the generated output would be pointless since the next generation would reproduce the same bugs. The devserver mode was added as a practical middle ground. Next session should fix the generation pipeline to produce compilable Angular 20 code, after which the entire rspack preview pipeline will activate automatically.
