Proposal / Agent Brain
User goals and model agents propose a bounded plan or candidate. The proposal may be optimized or rejected, but the proposer never grants itself execution permission.
A decision architecture that separates what AI proposes from what systems may actually execute. Explore the five trust domains behind DSG ONE.
Tap a domain or select a node in the 3D model. The description stays readable even when animation is disabled.
User goals and model agents propose a bounded plan or candidate. The proposal may be optimized or rejected, but the proposer never grants itself execution permission.
Each transition has an explicit contract. The route is conceptual—not a claim that any particular live E2E run passed.
Capture intent, constraints and candidate plan. Models generate options—not authority.
Check applicable deterministic constraints and bounded Z3 proof obligations.
Spacetime evaluates plan, principal, scope, policy and approval requirements.
Only permitted steps reach governed AWS API, MCP, browser or tool adapters.
Attach result, evidence, hashes and replay context. Incomplete proof is not success.
DSG may continue authorized work. Missing permission pauses an in-plan step; unsupported requests fail closed.
Within the approved plan. The scoped step meets required authority, capability, constraints and evidence conditions.
Still within the plan. A required permission or capability has not been provisioned. Resume after authorization.
Out-of-plan or unsupported. Policy violations, missing authority or failed proof cannot be converted to a success claim.
Verified 11 October 2026: AWS Spacetime source 5c09c3a68bebff32a543e543237cdd1b77a6b53c was activated with ECR image sha256:37c21d7947b624c742c63bafeb601c5ba8765021d788ca4aefd6d5b7eb0bc1c4. AWS activation run 38140649005 and signed read-only canary run 38140811436 passed; four peer containers were unchanged.
Scoped signed provider E2E: PASS. A real end-user OAuth principal executed the governed GitHub metadata read-only route. Provider/result and signed execution hashes, AWS SSM pinned public key, Ed25519 signature and tamper denial were independently checked. A fresh authenticated Production MCP readback on 11 Oct reported valid=true, records=140. This dated evidence does not prove Cinema remote Connect/Execute, Quest/Unity or whole-system E2E.
