📋 Decision Context

Question:

How to fix 4 new build failures discovered in full monorepo build (widgets, singularity-lib, space-map-lib, universe-explorer)?

Task: Not specified

🎯 Decision Made

Chosen:

Fixed all 28 TypeScript errors across 4 libraries: 1. widgets - Added resolveJsonModule + type annotation, 2. universe-explorer - Switched to custom builder (ng-packagr bug), 3. singularity-lib - Fixed 9 strict null checking errors with proper guards and type assertions, 4. space-map-lib - Fixed method names (setSelectedUniverse→selectUniverse), removed non-existent file export, fixed array access. All 4 libraries + 44 dependencies now build successfully.

Options Considered:

1. Fix each library individually
2. Fix all systematically in one session

💭 Reasoning

Full monorepo build revealed 4 hidden failures only visible when building with all dependencies. Root causes: (1) JSON module resolution not propagated to consumers, (2) ng-packagr bug in universe-explorer, (3) Strict null checking across singularity-lib requiring explicit guards, (4) Wrong method names and missing file in space-map-lib. Fixed all 14 files systematically. Session 71 total: 20 libraries, 78+ errors fixed, 100% success rate.
