Conversation
Introduces a typed data contract model (1:1 per catalog table) with column-level rules (not_null, unique, dtype, value_range, allowed_values, regex, custom_expression) and general rules (Flowfile expressions). Each rule provides a to_expression() method returning a Flowfile expression string, keeping the validation engine thin and rule logic self-contained. Includes: - DataContract DB model, repository, service CRUD, and API endpoints - Validation engine shared between catalog contracts and the new data_validation flow node (pass-through with _is_valid/_violations columns) - Auto-generate contract from table profile - mark-validated endpoint for tier-2 validation flows - ContractSummary on CatalogTableOut for catalog UI status badges https://claude.ai/code/session_01RJ6iAh4f3MN7UdzttruKho
✅ Deploy Preview for flowfile-wasm canceled.

Validation now auto-marks the contract at the current table version and fires downstream table_trigger schedules on success. Overwrite no longer triggers downstream flows — the contract must pass first. Also fixes self._repo → self.repo bug in service contract methods and improves storage format detection in the validate endpoint. https://claude.ai/code/session_01RJ6iAh4f3MN7UdzttruKho
