Source hierarchy.
- Primary: manufacturer specifications, manuals, homologation databases, regulators, charging networks, and government agencies.
- Corroborating: independent test organizations and established technical publications.
- Context: reporting that explains availability, changes, and market conditions.
Specifications are not blended.
WLTP, EPA, and CLTC range values are kept separate. Gross and usable battery capacity are labelled when known. A peak charging rate is not presented as an average charging rate. If a specification varies by trim or market, the page says so.
Facts, estimates, and unknowns.
Official facts link back to a source. Calculator results are clearly identified as estimates and show their inputs. If a value cannot be verified confidently, Charjin says it is unknown rather than filling the gap with a plausible number.
Marketplace verification.
A checked listing field means Charjin has received evidence for that specific field; it does not mean the entire vehicle has passed an inspection. Dealer identity, mileage, regional specification, warranty, battery health, and accident history retain separate states so missing evidence stays visible.
Paid placement must be labelled and must not change the underlying verification method or editorial conclusion.
Original stories.
External reporting is a discovery signal, not copy to be disguised with new wording. A Charjin story must add its own question, structure, analysis, and consumer conclusion. Material claims link to primary documents, manufacturer information, or independent research, and sourced facts remain distinguishable from the Charjin view.
Every published original includes answer-first guidance, sourced common questions, an evidence register, related buyer guides, a licensed image record, and links to current reporting on the same subject. A story is not published until a human reviewer checks the claims, citations, dates, image licence, market context, and conclusion. The article records its publication date, latest review, and corrections.
Source briefs.
The briefing records a publisher headline, short feed excerpt, publication date, topic, and canonical URL. Charjin then publishes an internal source brief with a new headline, a consumer question, why the development matters, what to watch next, and relevant buyer guides. The publisher is named prominently and the original report remains one click away.
Publisher images are not assumed to be reusable. Charjin brief pages use a locally stored image with recorded permission or a clearly labelled Charjin context visual; the caption states when it does not depict the reported event. A source brief is not presented as independent Charjin reporting. It carries a single-source evidence notice and remains excluded from search indexing until primary evidence, independent context, image rights, and a human review meet the standard for a Charjin original.
Update discipline.
Source candidates can be collected automatically. Material changes require a new check date, and high-impact claims should be verified against a primary source before publication. Corrections should update the page and its source record.
