 ### Decisions
 
 Key decisions made during v2.0 execution:
+
 - [14-05] Used postgres.js unsafe() for sequence reset DDL instead of drizzle-orm sql template
 - [14-05] Row-by-row inserts for better error diagnostics during migration
 - Platform pivot: single-user to multi-user with discovery-first approach
@@ -54,6 +56,8 @@ Key decisions made during v2.0 execution:
 - Structured UGC only — ratings and predefined fields, no freeform text until moderation
 - Separate globalItems table — not a flag on user items table
 - Single-user SQLite mode diverges at v2.0 boundary
