Sources and retrieval

Full-text and semantic search retrieve matching passages from Postgres. The signed-in workspace can open complete documents. Public examples use fictional material; case files stay behind authentication.

Citations and review

Retrieved passages carry document IDs and source paths. Answers list the documents they cite. Citation checks identify missing references; they do not establish that a passage supports every claim. A lawyer reviews the answer against its sources.

Release checks

Changes pass the required checks in a merge queue. Cloud Run deployments probe a candidate before promotion and retain a rollback revision.

  • verify
  • protected code/config scan
  • CodeQL gate

Release checks assess delivery behavior, not legal accuracy.
