Interface RenderArticleInput

Aggregated markdown (front-matter + body) produced by aggregateAnalysis.

Language code.

Canonical path (e.g. news/2026-04-23/propositions-en.html).

Hreflang alternates map (optional).

Subfolder github tree link used in the analysis references block.

Ordered list of artifacts used (shown in the footer).

Raw English executive-brief.md markdown adjacent to article.md. When provided, the renderer derives <title> (from the brief H1 via cleanArticleTitle) and <meta description> (from the BLUF via composeRichDescription / readBlufParagraph → truncateToSentenceBoundary) directly from the brief, bypassing the (now back-compat-only) article.md frontmatter title: / description: lines.

When omitted (the 278 pre-2026-03-26 legacy news/*-en.html articles whose analysis/daily/<date>/ source directories have been deleted), the renderer gracefully falls back to whatever article.md frontmatter is available — keeps existing legacy SEO intact without throwing.

The subfolder slug (propositions, committee-reports, …) is sourced from subfolderSlug; defaults to the empty string which simply skips the article-type boilerplate scrub inside cleanArticleTitle.

Raw localized executive-brief_<lang>.md markdown when one exists for input.lang. When provided and lang !== 'en', the renderer derives title + description from the localized brief (per the cascade-chain step #2 in Article-Generation.md § "Per-language precedence chain"); when the localized brief has a banned / missing H1 / BLUF, fields independently fall through to the englishBriefMarkdown cascade.

Subfolder slug (propositions, committee-reports, …). Forwarded to cleanArticleTitle so brief H1s that simply repeat the article-type label are scrubbed before truncation. Optional; an empty string disables that scrub.
