# Force Merge Batch

`POST /api/v1/file-folders/{folder_id}/batches/{batch_key}:force-merge`

Escape hatch for a stuck batch (e.g. timed out at 9/10 files): seal
whatever live members currently exist for ``batch_key``, ignoring the
folder's configured ``batch_size``.

Reuses the exact shared seal path (``application.operations.seal_batch.seal_batch``)
and advisory lock as the automatic Nth-file seal, so force-merging is
indistinguishable from a "natural" seal to every downstream reader.

## Path parameters

- `folder_id` string, uuid, required
- `batch_key` string, required

## Response `200`

Successful Response

- object

## Other responses
