Merged
Conversation
- Wrap raw user queries in UNTRUSTED_DATA boundary markers in query_agent.py and reranker.py using wrap_external_content from core.safety.content_wrapper - Sanitize dataset content (question/answer/subject snippets) in reranker prompts using sanitize_prompt_literal to strip injection patterns and Unicode control characters - Add QDRANT__SERVICE__API_KEY env var support to docker-compose.yml (SEC-H5) - Replace hardcoded postgres password in Helm values.yaml with empty required placeholder (SEC-H6) - Add auth/billing/CORS/Qdrant config fields to Helm values.yaml (SEC-M7) - Expose SUPABASE_URL, SUPABASE_JWT_SECRET, POLAR_WEBHOOK_SECRET, QDRANT_API_KEY as k8s Secrets in Helm secret.yaml and deployment-api.yaml - Add 18 unit tests in tests/unit/test_prompt_safety.py covering injection stripping, boundary marker wrapping, and unicode control char removal Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
