Localize executive-brief lead in news HTML + sharpen brief headline tradecraft

[Copilot]

Non-English news pages opened with the English executive brief even when a localized executive-brief_<lang>.md existed, and every page embedded all 13 localized briefs inline as ## Executive Brief Sv/De/… carrier sections (a representative proposition page was ~428 KB). The localized brief was only feeding the SEO <title>/<meta description> cascade — never the on-page body lead.

This brings the on-page lead into lock-step with that SEO cascade (localized if it exists, English otherwise) and strips the inline carrier bloat.

Changes

• New scripts/render-lib/article-brief-lead.ts — pure (no-I/O) markdown transform applied by renderArticleHtml per language:
  • stripEmbeddedLocalizedBriefSections() removes every ## Executive Brief <Lang> carrier for all languages.
  • For non-English with a localized brief, the first <h2> lead-section body (## What Happened) is swapped to the cleaned executive-brief_<lang>.md — reusing the aggregator's cleanArtifactBody + rewriteRelativeLinks pipeline, deliberately skipping normalizeNarrativeTerminology so English first-use glosses never leak into localized prose. Lead heading stays the language-stable English ## What Happened (TOC localizes its label separately); provenance comment repoints to executive-brief_<lang>.md.
  • English, missing-brief, and empty/whitespace-brief all retain the English lead — mirroring SEO fallback layer Fix MCP server paths and add rule-based Copilot instructions #4.
• Wired into scripts/render-lib/article.ts renderArticleHtml.
• Carrier exclusion from the artifact list — resolveArtifactList (render-articles.ts) and isReaderGuideEligible (aggregator/reader-guide.ts) now skip executive-brief_<lang>.md, so they no longer surface as Reader Intelligence Guide rows (which would dangle once the body carriers are stripped), Article Sources cards, or JSON-LD isBasedOn. They are translations of executive-brief.md, not independent analytical artifacts.
• analysis/methodologies/ai-driven-analysis-guide.md — added a 🪝 Headline-tradecraft block (named actor + active verb + concrete stake, SERP-safe ≤70 chars, no date-stuffing, localize the angle not the words) and made Step 2B / Step 7 explicit that the brief H1/BLUF is now the on-page lead in every language, not just metadata.
• Article-Generation.md — documents the on-page lead localization step alongside the existing metadata cascade.
• tests/article-brief-lead.test.ts — 12 cases: carrier strip across all langs incl. EN, localized swap, EN passthrough, missing/empty fallback, provenance repoint, front-matter/H1 cleaning + ##→### demotion, legacy ## Executive Brief H2, single-H2 lead.

Analysis findings (requested)

• article.md completeness: all 22 root analytical artifacts on disk are aggregated (each carries a source: comment) — no valuable content is missing. The sole redundancy was the 13 translation carriers, which are functionally dead weight in HTML (SEO reads executive-brief_<lang>.md from disk, not the embedded copies) and are now stripped at render.

Notes

• Verified renders for sv/ja/ar/en (2026-05-20/propositions): localized lead present, no English leak, zero carriers, ~428 KB → ~307 KB. Sample page renders were reverted — bulk HTML regeneration lands as its own dedicated commit per repo convention, so this PR is code + tests + docs only.
