| observation:electrical.system_energy_kwh | {"values": [], "note": "NOT silently resolved. The spec row (229 kWh) is recorded in system_energy_kwh because it is the measured nameplate and it reconciles exactly with the printed cell data (256 x 3.2 V x 280 Ah = 229.4 kWh), whereas 225 is only the marketing round-down embedded in the SKU. Both preserved."} |
| observation:physical.corrosion_grade | {"values": [], "note": "Not a true contradiction - two different products - but recorded because the defaults invert between siblings and a careless merge would blur them. Each record keeps its own datasheet's value."} |
