Conversation
Keys containing characters outside [a-zA-Z0-9_-] were passed through to providers and caused obscure SQL errors (e.g. OperationalError: near ";": syntax error) surfaced as 500 responses. Add a Pydantic field_validator on ComparisonFilter.key (matching the existing pgvector pattern) so users get a helpful validation error at the API boundary explaining which characters are allowed.
