# Internal Lookup Documents

`POST /v1/documents/internal/lookup`

Agent-facing lookup endpoint, authorized via internal-secret header.

Resolves the session's attachments via the interview→template chain and
calls the same retrieval engine the public route uses.

The agent passes its own `self._session_id`, which is the LiveKit room
name (not a Postgres UUID). We resolve via `_resolve_session_id` — the
same helper /v1/sessions/internal/trace uses — so either form works.
