Published source families
SerialAtlas keeps attribution in the interface and repository. Sources support a rule; they do not make SerialAtlas an official manufacturer service.
Inspector Handbook open data
Structured manufacturer reference data published under Creative Commons Attribution 4.0, independently implemented and tested here.
Open source indexOfficial manufacturer sites
Used for ownership, current product categories, support routing, and confirmation when public documentation is available.
Regression fixtures
Sanitized examples test dates, invalid values, repeating cycles, normalization, and future-date rejection. They are not customer lookup logs.
What is not collected
The core tool does not create a server-side database of serial numbers or photos. Optional history stays in the visitor’s browser.
