# Save a markdown document

PUT https://api.cloudraker.com/workspace/sessions/{sessionId}/artifacts/{artifactId}/content
Content-Type: application/json

Writes new bytes and bumps the SAME artifact to the next version — `/documents/:id` keeps its address — and puts one `artifact` entry on the timeline carrying `summary`. Send `baseVersion` — the version you edited — and a save that would overwrite a newer one answers 409 `document_version_conflict` instead. Without a `summary` the platform generates `+N/−M lines` from the diff. **Authorization:** the same gate as every session route — `work_session:read` (or `comment` to write) on the session, OR `space:contribute` on one of its linked spaces; a desk session only for its owner. Any denial is 404.

## Response

### 200

The new version of the artifact.

## Errors

### 400 Bad Request Error

`validation_failed` — a malformed body.

- `error` (string, required) — The sentence a human reads.

### 404 Not Found Error

No such session or artifact, or the caller may not see it.

- `error` (string, required) — The sentence a human reads.

### 409 Conflict Error

`artifact_not_ready` — the bytes are not stored or parsed yet (retryable); `document_version_conflict` — a save whose `baseVersion` is behind the current version.

- `error` (string, required) — The sentence a human reads.
- `error_code` (string, required) — The stable snake_case branch key.
