# Starts an asynchronous computation of the benchmark's prompt embedding map.

`POST /benchmark/{benchmarkId}/prompt-embedding-map`

Restricted to platform staff. Computing a map is what decides whether a benchmark exposes one
 on the anonymous read route, so it is a curation call rather than a benchmark-owner capability
 — a benchmark's owner cannot trigger or re-trigger it.
 
 Returns a tracking id immediately; poll
 GET /benchmark/{benchmarkId}/prompt-embedding-map/status for progress. Responds with
 409 Conflict when no embedding provider is configured, or when a computation for this
 benchmark is already in flight. Any map already being served stays in place until the new one
 succeeds, so triggering a recomputation is safe.
