Setup
Charge crank fully (to storage mode on the Victron 25A), disconnect, record voltage + time. Re-measure ~12h later.
Pass criteria (written in advance)
Morning voltage roughly equals the settled evening voltage — TJM was the leak
If it fails
Voltage slides toward 9.8V again — drain is elsewhere; hunt continues with the sparky
