# Pre-warm sessions cache for the active project

`POST /sessions/warmup`

Pre-warm OpenSearch shards + Redis list cache for the active project.
Fire-and-forget: returns {ok:true} immediately while the warmup runs in
the background. Triggered from the frontend right before a session query
is likely (sidebar hover, global search modal mount, RecipientPicker mount,
periodic refresh while on the Sessions page) so the user doesn't pay the
cold-shard penalty on first interaction.

## Headers

- `project` string, required

## Response `200`

Ok

- object
  - `ok` boolean, required
