Memories and sources matching a search, newest first, in two paged groups. Each entry's id is what the lineage and timeline reads take as a root.

## Query parameters

- `search` string
- `ingestionId` string, uuid
- `first` integer
- `afterMemories` string
- `afterSources` string

## Other responses

- `400`: The request is malformed or violates a field constraint. Match behavior on the response code field.
- `401`: missing-api-key: no bearer. malformed-api-key: the header or the key has the wrong shape, or an agent token was sent to a route that accepts keys only. unauthorized: the key is unknown, expired, revoked, or of the kind this route refuses, or the agent token is invalid or expired.
- `403`: project-archived: the project of the key, or the project an agent token names, is archived. Unarchive it in the console to resume. insufficient-scope: the agent token does not carry the scope of the route.
- `429`: The plan's requests per minute are exceeded. This refusal carries no body.
- `default`: Any other failure uses the same JSON error envelope.
