Mundi QMD — Lead-Enricher Supabase Writer Integration

Overview

The apps/lead-enricher/ stack has a SupabaseWriter class that's fully written and tested but never wired into the production waterfall. This skill codifies the wiring + the companion problem: PeopleDataLabs' free tier (100 enrichments/month) blocks production usage.

Two tasks this skill handles:

1. Wire SupabaseWriter into waterfall.py as the terminal step.
2. Swap or tier-up PDL for higher-volume provider.

When to use

• Shipping lead-enricher from staging to production
• Scaling beyond the 100/month PDL cap
• Adding a new enrichment provider to the waterfall
• Debugging "enrichment runs but nothing in Supabase" (the exact bug this wiring fixes)
