`DELETE /api/v0/knowledge-bases/{kb_id}/graph`

## Request

- URL: `https://api.outerport.com/api/v0/knowledge-bases/{kb_id}/graph`

- TypeScript: <https://skmtc.dev/outerport/apis/outerport-api/docs/api/v0/knowledge-bases/:kb_id/graph/delete.ts> (a function with typed inputs; its response is checked against the schema)

Deletes every graph-derived row for the collection (nodes, edges, custom entity and relationship types, and package subscriptions) while the collection itself and its documents survive. If extraction provenance, current/historical claims, or resolutions exist, the request returns 409 unless discard_evidence=true explicitly permits their permanent deletion. Export an archive before discarding them.

## Path parameters

- `kb_id` string, uuid, required

## Query parameters

- `discard_evidence` boolean: Explicitly and permanently delete all extraction runs, extraction sources, current or historical attribute claims, and fact resolutions with the graph.
