 # Excititor · VEX Raw Collection Validator (AOC-19-001/002)
 
+> **DEPRECATED:** This document describes MongoDB validators which are no longer used. Excititor now uses PostgreSQL for persistence (Sprint 4400). Schema validation is now performed via PostgreSQL constraints and check constraints. See `docs/db/SPECIFICATION.md` for current database schema.

 - `$jsonSchema` validator applied to `vex_raw` (migration `20251125-vex-raw-json-schema`) with `validationAction=warn`, `validationLevel=moderate` to surface contract violations without impacting ingestion.
 - Schema lives at `docs/modules/excititor/schemas/vex_raw.schema.json` (mirrors Mongo validator fields: digest/id, providerId, format, sourceUri, retrievedAt, optional content/GridFS object id, metadata strings).
 - Migration is auto-registered in DI; hosted migration runner applies it on service start. New collections created with the validator if missing.
