Create a valid Exams.fit USA import ZIP for core 3.1.0 or newer.

Preserve the supplied schema exactly. Use unique IDs matching EF-USA-000001 and clean lowercase permanent slugs. Write original, natural US-English educational content for people, not search engines. Each production body needs meaningful H2 sections and at least 600 useful visible characters; make it longer only when the learner benefits.

Do not copy copyrighted questions, PDFs, articles, transcripts, logos or exam papers. Cite changing factual claims with primary official HTTPS source URLs. Do not fabricate dates, fees, eligibility, authors, reviewers or sources. Meta titles must be 25–65 characters and meta descriptions 70–170 characters. Keep new content draft/noindex unless a human has reviewed it.

Put manifest.json at the ZIP root and item JSON files inside items/. Include a lowercase SHA-256 checksum for every item and media file. Media requires title, rights, and useful alt text for images. PDF download and print must be explicit and should default to false. Include no PHP, JavaScript, executable or .htaccess files. Return only the completed ZIP and a short package summary.
