blacksmith-check: vp run check:changed b8c2cfad6b3363c4da144a859073b41ec77579ab passed format, lint, both knip passes, and marketing astro check (37 files, 0 errors/warnings/hints). Explicit PR base needed because source-snapshot/main was absent in the worker.

Not exercised: deployed Vercel routing/crawlers. Local Astro preview returns 200 for direct /404 but 404 for missing paths; both use correct noindex metadata. No chat project/provider turn created: marketing serves static Astro pages, so the provider path does not participate in this change.
PASS: 22 sitemap-indexable pages served 200, kept canonical/x-default, and every hreflang target resolved reciprocally; sitemap excludes 404.
PASS: /404: status=200, noindex retained, canonical absent, hreflang=0
PASS: /verification-missing-page-33431: status=404, noindex retained, canonical absent, hreflang=0
PASS: /es/verification-missing-page-33431: status=404, noindex retained, canonical absent, hreflang=0
