🏗️ Architecture: How to ensure platform builder (universe-by-universe/project...

📋 Decision Context

Question:

How to ensure platform builder (universe-by-universe/project) works perfectly with all tools synchronized?

Task: Session 28.3 - Platform Builder Validation

🎯 Decision Made

Chosen:

Do systematic end-to-end validation with honest assessment

Options Considered:

1. Continue claiming production ready without testing
2. Do systematic end-to-end validation
3. Focus only on wiring without validation

💭 Reasoning

Initial work (28.1-28.2) wired up CrossToolSyncService across 11 tools, but validation was skipped. Session 28.3 revealed: (1) Infrastructure is solid - all services running, Flash Persistence working, BroadcastChannel API integrated; (2) BUT cross-tool sync is UNVALIDATED - no end-to-end tests of module creation propagating across tools; (3) Error handling UNTESTED - unknown behavior when backend down, invalid data, or concurrent edits; (4) Performance UNKNOWN - no load testing with 100+ modules. Honest confidence dropped from 95% to 75% after reality check. Platform needs 4-6 days of focused testing before truly production-ready.
