Purchase proof
Receipt-backed purchase is locked in.
Best Buy and 339.00 are supported by uploaded receipt evidence.
Model proof
Model is captured, but proof is still thin.
The model string is stored, but a product label or photo would make it more credible.
Warranty trail
Warranty timing is backed by uploaded proof.
Warranty is tracked through 2026-10-03 with a manual or warranty file attached.
Care history
Future upkeep is scheduled, but completed care is still light.
The schedule exists, but logging real upkeep or replacement proof will make this record more trusted.
