Build on the Dewwit corpus.

Run live retrieval queries against the corpus with filter constraints (supervision mode, trust tier floor, quality score floor, language). Each result records a billable RetrievalEvent — same flow your production integration will use.

Every chunk you retrieve carries a proof stamp. Click “Verify proof stamp” on any result and the browser fetches the JWKS and verifies the Ed25519 signature locally — no Dewwit-side trust beyond the public key set.

Every chunk declares its supervision mode (human-authored, human-led + AI assist, AI-drafted human-reviewed, or AI-orchestrated) — validated against measured behavioral signals at production time. Filter retrieval to your training need.

EU AI Act Article 53(1)(d) training-data summaries fall out of the proof-stamp chain as a byproduct. Consent and revocation propagate within 90 days. The retrieval ledger is append-only and auditable per provider.
