List Harbor Saved Queries

Lists current published saved queries for a Harbor. Saved queries are supported only for Polytomic-managed Harbors whose backing Connection type is `polytomic_harbor`. Collection items contain current published metadata and omit SQL, parameter values, and unpublished drafts. A Harbor profile credential can list saved queries only when `harbor_id` identifies its own Harbor. ## Harbor Activity When you use a Harbor profile credential, send a new nonzero UUID in `X-Polytomic-Activity-Request-ID` for each request, including each page. A missing or invalid ID returns `400 Bad Request`. Reusing a consumed ID returns `409 Conflict`. If you supply `X-Polytomic-Harbor-Session`, the session must be active and bound to your credential and Harbor. An invalid session returns `403 Forbidden`. Direct scoped REST requests may omit the session header. Polytomic records `saved_query.listed` before returning data. The event describes only the returned page, including saved-query IDs, immutable revision IDs, version numbers, and bounded name snapshots. Activity excludes SQL, parameter values, and expected column names. If Polytomic cannot record the event, the request returns `503 Service Unavailable` without saved-query data.
