## 1. Stream Artifacts - [x] 1.1 Create the architecture delivery stream proposal. - [x] 1.2 Create the delivery stream design with ordered backlog decisions. - [x] 1.3 Create the delivery workflow spec with backlog, handoff, closure, ownership, and progress requirements. - [x] 1.4 Create the delivery progress record with queue status and handoff template. ## 2. First Concrete Change - [x] 2.1 Create the `establish-development-runtime-baseline` OpenSpec change. - [x] 2.2 Add proposal, design, specs, and tasks for the runtime baseline change. - [x] 2.3 Add a fresh-chat handoff block to the runtime baseline tasks. ## 3. Verification - [x] 3.1 Run `scripts/check-structure.sh`. - [x] 3.2 Run `openspec validate architecture-delivery-stream --strict`. - [x] 3.3 Run `openspec validate establish-development-runtime-baseline --strict`. - [x] 3.4 Confirm OpenSpec status shows both changes have required artifacts present. ## Evidence - `scripts/check-structure.sh`: passed. - `openspec validate architecture-delivery-stream --strict`: passed. - `openspec validate establish-development-runtime-baseline --strict`: passed. - `openspec status --change architecture-delivery-stream --json`: proposal, design, specs, and tasks present. - `openspec status --change establish-development-runtime-baseline --json`: proposal, design, specs, and tasks present.
