Update the summary for an assessment

Replaces the assessment summary with an edited version, the same as editing it in the app. The generated summary is kept: the edit is shown in its place, is recorded in the summary's edit history, and is discarded when the summary is regenerated (which happens automatically when a new assessment completes). Only the summary of a completed assessment that has an AI-generated summary can be edited.

Send the summary as Markdown (format=markdown) to have it rendered with the report's styling, or as HTML. Either way, unsupported markup (scripts, event handlers, external stylesheets, remote images and so on) is removed before the summary is stored. Images must be embedded as data: URIs.

To avoid overwriting a summary that changed after you read it, pass the version from the read; the update is then rejected with 409 Conflict if the summary is no longer that version.

Returns the updated summary in the same format it was sent in.
