Concurrent handover-document incident

Unnamed: a user running concurrent agent sessions · workflow agent

What happened
A user reported that several concurrent agent sessions overwrote the same handover document three times overnight on 9 to 10 September. Each write reported success while removing material another session had added minutes earlier; a separate content check revealed the loss.
Impact
Records of which live sources had been checked were lost (reported). No version history was available to restore the document.
What would have caught it
Reject a write when the document has changed since the agent read it. Alert on large drops in document size and keep version history.
