Problem

A B2B export site for a rubber-components manufacturer: eleven product categories with SKU pages, industries, an export map, case studies, resources, legal pages and enquiry forms. The Figma comps disagreed with each other and with the research pack: five different founding years, six export-country counts, three minimum order quantities, three response-time promises. Shipping any of those wrong would have cost the client credibility with buyers who check.

Correctness as a build step

If content is wrong, the build fails with the field path. Nothing unverified reaches production.

Before and after

BeforeAfter

Contradictory factsWhichever comp the developer copied fromOne facts registry; unconfirmed values are null and render as nothing; a forbidden-claims list

Broken linksFound by visitors13 broken hrefs and 23 lists keyed by href caught by a build gate

SKU pagesFour silent 404s from a missing collection case, YAML null, an SEO budget and an h1 length rule rejecting "C Pad"All rendered; 29 legacy WooCommerce URLs mapped with 301s

Enquiry formsNine forms on six pages, two would have posted emptyOne endpoint, eight canonical columns, honeypot and time-to-submit, a 60-assertion field-map test

MotionAnimation library for the export mapCSS scroll-driven timeline, no JS, no client boundary

Judgment calls

I declined to draft legal copy and left those pages as structured blocks for the client’s counsel. Founding year and export counts stayed null until the client confirmed them. Client work; no visuals here, live URL to follow when the domain goes up.

Learned: Hold unknown facts as null, never guess. A build gate is cheaper than an apology.
