Goal
Ship a small collaborative prototype and validate its runtime behavior in one day.Step 1: Align on model and contracts
Read:quickstartarchitecture/mental-modelsdk/javascript
- You can describe your target room boundaries and write/read paths.
Step 2: Run host + app surfaces
Usedeveloper-experience/apps to start host and app surfaces.
Outcome:
- All surfaces run against a shared room id.
Step 3: Implement first product behavior in demos
Use baseline patterns from:apps/demos/infinite-room-workspaceapps/demos/collab-maps
- one shared state write path
- one collaboration signal/presence path
- one failure-state message in UI
- You have one deterministic interaction path that converges across two peers.
Step 4: Validate runtime evidence
Use:apps/playground/protocol-inspectorapps/playground/replay-lab
- filtered protocol trace snippet
- replay snapshot before/after interaction
- You can prove behavior with trace + replay evidence, not just screenshots.
Step 5: Harden minimum operator posture
Review:operators/server-setupoperators/security-and-authoperators/troubleshooting
- You can explain minimum deployment and incident posture for your prototype.
Exit checklist
- Shared behavior converges in two windows.
- Failure states are surfaced in UI.
- Protocol/replay evidence captured for one user workflow.
- App links and runbook notes are documented for teammates.
