Append File History

Records a change to a file as one row in the workspace's change log. Each row gives the file its next version number and holds what was done (created, changed, deleted or renamed), a summary of up to 60 words, the part of the file touched, and the task that asked for the change, so the change can be traced back to the request.

For text files under a size limit it also stores a SHA-256 fingerprint and the byte count of the file at that moment. If you say a file was created but the log already has entries for it, the row is recorded as a change and the reply says so.

Every row is marked as written by an automated worker, whatever the caller sends, and it never touches review ratings. It currently runs inside Syvon.
