Which sources take priority?
| Priority | Source class | Use |
|---|---|---|
| 1 | OEM technical document for the exact market and model year | Preferred specification source |
| 2 | OEM owner manual, data book, guide, bulletin, or official product page | Used when configuration and conditions are explicit |
| 3 | Government vehicle dataset, including NHTSA | Used for identity or fields the dataset directly publishes |
| Not sufficient alone | Dealer pages, forums, aggregators, unsourced snippets, or generated answers | May identify a lead but cannot establish a production value |
How does SpecAxle separate data from commentary?
Specification tables contain source-backed records. Explanations may describe formulas, definitions, and safety context, but explanatory text cannot override a vehicle’s stored source record.
What is SpecAxle’s AI policy?
AI may assist candidate extraction only when each candidate includes an exact source quote and page number. Automated checks confirm that the quote exists. A language model never fills gaps, resolves conflicting sources, or publishes a specification from memory.
What does “Last verified” mean?
“Last verified” is the date SpecAxle checked the stored value against its cited source. SpecAxle does not move verification dates for cosmetic edits, page-template changes, or search optimization.
How are corrections handled?
SpecAxle evaluates correction reports against primary evidence. Confirmed changes update the value, source relationship when needed, and verified date. Rejected changes leave the sourced record intact. Report evidence through the contact page.
Do ads or licensing affect specifications?
No. Advertisers and licensees do not choose sources, values, verdicts, correction outcomes, or related-vehicle rankings. Paid placement must not be presented as a verified specification.
