AI Vendor Data-Trust Index

A source-cited record of how AI products handle your data — whether the vendor trains on your inputs, whether zero data retention is available, and whether you can opt out — across 11 products (OpenAI, Anthropic, Google Vertex & Gemini, Azure OpenAI, AWS Bedrock, Microsoft 365 Copilot, GitHub Copilot, Mistral, Meta Llama). Every value carries a verbatim quote from the vendor's live policy, a source URL, a confidence level, and the date it was checked. Ambiguous cases are marked unclear rather than guessed. An automated verifier re-checks the policies weekly and only publishes a value when a verbatim quote supports it — otherwise it holds the last human-verified value.

Deploy

cd ai-trust-index
npm install
npm run db:create                 # → paste the returned database_id into wrangler.jsonc
npm run schema:remote             # create tables (drops existing)
npm run seed:remote               # load the 6-vendor provisional seed
npx wrangler deploy --dry-run --outdir dist   # verify build (no auth)
npm run deploy                    # deploy the Worker
# In Cloudflare: add custom domain trust.oscar-lopez.com to this Worker.

Verifier (v1) — automated weekly re-check

Pipeline in src/verifier.ts: fetch each vendor's pinned policy URLs → content-hash diff (skip if unchanged) → model extraction of {value, quote} (Workers AI by default; frontier via AI Gateway if configured) → verbatim quote-verification (the candidate quote must be a literal substring of the fetched source, else rejected) → confidence gate. Only a quote-verified DEFINITE value auto-publishes (verified_by='auto'); anything else is queued in review_queue and the last good published value is held (never auto-downgraded to unclear). A failed fetch holds the last good value and flags the URL. Runs weekly via cron (0 12 * * 1) and on demand.

Admin endpoints (key-gated by STATS_TOKEN):

• GET /admin/verify?key=…[&force=1][&vendor=ID] — run the verifier now
• GET /admin/review?key=… — list open review-queue candidates
• GET /admin/review-resolve?key=…&id=N&action=approve|reject — approve (publishes as human) or reject
• GET /admin/verify-selftest?key=… — proves the quote gate rejects a fabricated quote / accepts a verbatim one

Extractor: defaults to Workers AI (EXTRACTOR_MODEL, needs no external key). To use a frontier model, set AI_GATEWAY_URL + AI_GATEWAY_TOKEN (secret) and point EXTRACTOR_MODEL at the provider model.
