Adapter Builder & Evidence Verifier

Two local tools backed by DSG Spacetime contract source. Author a bounded provider definition and verify integrity and signer identity without granting the browser execution authority. No token, password or production secret is required.

Compile Adapter Contract

Edit provider, capability, schema, risk and scope; compute the route contract hash locally.

Compilation is not registration or authorization.

Verify Evidence Locally

Paste a provider v2 receipt, Ed25519 attestation or Goal-first evidence for independent browser recomputation.

Trust requires a separately pinned public key.

The execution authority remains in Spacetime

Plan → Route/Entitlement → Verified OAuth scope → Policy/Approval → exact payload binding → Provider Adapter → provider result → evidence/attestation → next governed action. These pages do not register routes, resolve approvals, start a browser, call a provider or read production credentials. Success on this page is not proof of Production Browser E2E.
