# File Session Endpoint

`POST /sessions/{session_id}/file`

## Request

- Base URL: `https://api.nicheangle.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.nicheangle.com/sessions/{session_id}/file`
- Auth: none declared

Mark a run FILED — the user closed it out (e.g. downloaded all assets).
Same 'done with it' semantics as publishing; moves the run from open → filed.
Idempotent: re-filing keeps the original filed_at.

## Path parameters

- `session_id` string, uuid, required

## Headers

- `authorization` string, nullable

## Response `200`

Successful Response

- unknown

## Other responses

- `422`: Validation Error
