How Flows works
Product walkthrough
Follow the public plan from grounding through the build handoff and the point where repository evidence is required.

Motion is reduced in your system settings. The video will only open when you choose it.
Play the 0:42 walkthroughWhat the receipt means: This walkthrough shows the gate, not a verified outcome. Approval requires a connected repository and independently checked diff, tests, preview, and CI.
Start from a project goal or connected repository and review the bounded implementation steps.
Keep the plan visible while handing the work to the connected builder or coding agent you prefer.
See where a connected project must supply its diff, test output, preview, and CI state.
The public plan has no bound repository, so it stops at the gate instead of turning a manual claim into proof.
Connect your repository or describe a new project.
Use Replit, coding agents, GitHub, or guided instructions.
Check the diff, tests, preview, and CI before calling it done.
Intent → Project → Plan → Build → Verify → Recover → Approve → Ship
Example
One complete plan produced a working 11-step application and passed 59 plan-defined checks.
Partially validated — The plan and checks came from the same workflow, so this is not independent certification.
