Workbooks
Server-backed workbooks group imported sheets, derived views, pivots, joins, reports, and dashboard previews.
Storage mode: degraded. No supported Postgres URL env is configured. Supported env names: DATABASE_URL, POSTGRES_URL, POSTGRES_PRISMA_URL, POSTGRES_URL_NON_POOLING, DATABASE_URL_UNPOOLED, CORE_DB_POSTGRES_URL, CORE_DB_POSTGRES_PRISMA_URL, CORE_DB_POSTGRES_URL_NON_POOLING. Server APIs expose public read-only empty state; browser imports are saved as explicit local previews.
No server-backed workbooks yet
Browser-local workbook drafts still work through Add Sheet. Protected server persistence becomes active when a supported Postgres URL env and PLATPHORM_API_KEY are configured.
