6.7 Cummins Tuners & Deletes

How this article was produced, and how every claim is known to be accurate and sourced. Publishing is paused — this is a dry run.

1. The published article

This is the exact article.html the pipeline produced — the 29-element page that would go live on the blog (brand styling, table of contents, Key Takeaways, the compliance notice before the body, FAQ, numbered Sources, and the machine-readable Article + FAQ data). Publishing is paused; nothing was sent anywhere.

Every article moves through the same numbered stages. Each move is recorded in the article's manifest.yaml with who did it and when — the article cannot skip a gate.

3. QA Gate 1 — the outline, before a word was written

Before drafting, five independent checks run on the outline. This is where the system refuses to build on an unsupported claim. Each check reports how many items it looked at, how many failed, and out of how many (checked / failed / denominator).

4. QA Gate 2 — the finished draft

After the full article is written, five verifiers re-check the finished draft — product accuracy, legal accuracy, citations, competitor safety, and structure — and an adjudicator decides the outcome. In this zero-cost run the legal and citation checks are deterministic (exact-match against the sources), which is stronger than an AI opinion and needs no paid API.

5. Claim-accuracy table — every claim, traced

This is the heart of the proof. Every checkable claim in the article is listed with: the single-source-of-truth it draws on (LEGAL-SSOT = the legal folder, PRODUCT-SSOT = the product catalogue, OEM-TECHNICAL = manufacturer spec sheets), the source's own words (“before”), the verdict, and how it was checked. “After” — our paraphrase — is the claim text itself in column 2.
