# Disconnect Source

`DELETE /knowledge-graph/connections/{source_slug}`

## Request

- Base URL: `https://api.evidenso.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.evidenso.com/knowledge-graph/connections/{source_slug}`
- Auth: HTTP bearer

Hard-reset disconnect for a single integration.

Behavior:
  1. Delete every Composio `connected_account` for this
     (user_id, toolkit_slug). Source of truth for connection state
     lives in Composio (see `GET /connections`); once removed, the
     next /connections poll returns no row for this slug, so the UI
     badge naturally flips to "Not connected".
  2. Best-effort: clear the access-policy grants so a future
     re-connect starts at access_mode='none' (Settings UX) rather
     than carrying a stale "selected" set the user can't see.

Already-ingested Bronze data and existing societies are untouched —
they live in BigQuery / `bronze_doc_entity_links`. Only **future**
fetches break until the user reconnects.

Deliberate scope:
  We do NOT update `society_source_connections.status` for past
  societies that used this connection. That table is keyed by
  society_id, and mapping a Composio user back to "all societies
  this user owns" requires a join through organization_users +
  organization_societies that's bigger than this endpoint. The
  pipeline's refresh path re-resolves the live Composio account by
  `make_composio_user_id(uid, product_name)` rather than reading
  `composio_connection_id` from the row (the column is declared in
  the migration but currently never written — see
  `digital-twin-api/migrations/2026_05_society_source_connections.sql:23`),
  so a stale `status='connected'` on past rows is a UI hint that
  goes stale, not a correctness break. Refresh-on-disconnect for
  historical rows is a follow-up.

Returns the deleted account id list so the UI can log/toast the
outcome (`{"deleted": N, "deleted_ids": [...], "status": "disconnected"}`).
