📋 Decision Context

Question:

How does gmodules1 achieve platform generation compared to gspace1, and what should S226 adopt?

Task: Not specified

🎯 Decision Made

Chosen:

gmodules1 generates frontend-ONLY code. Backend is a shared generic UniverseDataController (port 3000) that handles ALL entity CRUD without per-entity code generation. gspace1 already has this backend. The gap is: (1) gmodules1 has a richer CRUD layer (BaseCrudApiService + BaseRepository + RepositoryRegistry + composables), (2) gmodules1 has module manifests with repository auto-registration, (3) gmodules1 has role-based permission derivation. S226 should use the SAME shared backend pattern and improve the frontend generation quality to match gmodules1's composable patterns.

Options Considered:

• No alternatives documented

💭 Reasoning

Key insight: NO backend code generation is needed. The shared backend-api's generic data controller already handles CRUD for any entity. What needs improvement is the FRONTEND generation quality: (1) Generated API services should extend BaseCrudApiService properly, (2) Generated forms need useCrudForm with real FormGroup (not empty signals), (3) Generated lists need the full useCrudList signature (sort, filter, pagination, selection), (4) Entity schemas should drive form field generation, (5) Seed data should be inserted during BackendSetupPhase. The 'universe_universe_' double-prefix exists because universe IDs include the prefix but collection name construction also adds it.
