- Add database/queries/{sources,rules,mappings,records}.sql — one file per
route, all business logic in PostgreSQL functions
- Replace parameterized queries in all four route files with lit()/jsonLit()
literal interpolation for debuggability
- Add api/lib/sql.js with lit(), jsonLit(), arr() helpers
- Fix get_view_data to use json_agg (preserves column order) with subquery
(guarantees sort order is respected before aggregation)
- Fix jsonLit() for JSONB params so plain strings become valid JSON
- Update manage.py option 3 to deploy database/queries/ instead of functions.sql
- Add SPEC.md covering architecture, philosophy, and manage.py
