- `errorCategory` / `errorReason`: sanitized only for failed rows
- Failed rows must not store prompts, full resident context snapshots, API keys, or raw provider errors.
- Knowledge retrieval may return enabled platform knowledge and enabled active-organization knowledge only.
- Knowledge retrieval first filters enabled platform / active-organization chunks in SQL, then computes cosine similarity in `modules/ai/server/knowledge.ts`; this keeps the MVP deployable on plain PostgreSQL without the `vector` extension.
- Completed elder analysis `resultJson.citations` must be derived from citation IDs actually referenced by `keyFindings[].citationIds` and `recommendations[].citationIds`; do not append unused available citations.

- Knowledge retrieval tests for platform shared, own organization, other organization, and disabled entry filtering.
- Knowledge retrieval tests for platform shared, own organization, other organization, disabled entry filtering, and cosine-score ordering from JSONB embeddings.
- Analysis tests for missing config, schema validation failure, failed-history sanitization, and data-scope redaction.
- Analysis tests for unknown citation rejection and referenced-only citation persistence.
- Route tests for auth/permission failures and standard response shape.
