Every figure below was fetched directly from goldstandard.org / globalgoals.goldstandard.org for this note. The question: not whether Gold Standard's multi-outcome model is real (it plainly is) but what evidence an impact-quantification report is built from, and whether a proof-gated field receipt could sit honestly beneath it.
No jargon. Gold Standard's multi-outcome model is real and credited below; the one fresh gap is worth naming plainly: here's what closing it is worth.
An agent-discovery file → the developers and buyers whose AI is weighing standards read Gold Standard's real methodologies, not a guessEvery agent-discovery path is a true 404 today, so an assistant asked which registry quantifies health, water, and soil outcomes has no machine-legible surface and paraphrases scraped marketing instead of Gold Standard's own SDG Impact Quantification toolset.
Gold Standard's own SDG Impact Quantification page describes methodologies and tools that quantify GHG emission reductions, carbon sequestration, soil organic carbon, methane reduction, water benefits, erosion impact, health outcomes (Averted Mortality and Disability-Adjusted Life Years), and waste-management impacts, stating directly that "multiple methodologies may be applied in one project." Projects using these alongside the GHG Emissions Reduction & Sequestration Product Requirements "may be issued with carbon credits" (GS-VERs): impact quantification and carbon issuance are explicitly linked, not separate tracks.

Gold Standard's own news page, titled "ICVCM Confirms Gold Standard's Clean Cooking Methodologies as Core Carbon Principles (CCP) Eligible," documents a specific, named methodology-category approval, not a blanket program pass. Clean cookstoves are also one of the few credit types with a directly-credited black-carbon co-benefit methodology, per EcoWealth's earlier public research on BeZero.

goldstandard.org ships a real robots.txt and sitemap.xml (95,868 bytes, HTTP 200): the files that tell search engines what to index, real SEO infrastructure, credited. But llms.txt (the file AI assistants read first), security.txt, ai.txt, and agent-card.json (the file that lets an AI assistant use a site correctly) all return an honest 404 with the identical branded template ("Error 404 | GS"), matching a nonsense-path control almost byte-for-byte: a genuine, consistent gap, not a soft-200 catch.

Gold Standard already treats impact as multi-dimensional at the project level, the same instinct EWP's own three-ladder library (Build/LBC, Grow&Cook/Michelin, Restore/SDG) anchors to at the packet level. But an SDG Impact Quantification report is still an aggregated document a VVB reviews periodically; nothing in that stack is a per-task, GPS-located, photo-and-signature-proven, on-chain-settled receipt. EWP is proposed as exactly that: a candidate evidence layer beneath the impact report, not a competing quantification methodology, and not a claim to issue a single GSVER.
