Coordinate UX acceptance testing

Run a goal-driven browser journey with a tester that has no repository context. Keep site preparation, private success checks, and product diagnosis in the coordinator context.

Prepare the run

1. Read the selected journey in acceptance/journeys/.

2. Check the journey's status and requires frontmatter. If its status is needs-profile, report the missing bootstrap requirements and stop. Do not substitute a simpler profile or relax the journey.

3. Read its site profile in acceptance/sites/ and the portable tester instructions in acceptance/tester/SKILL.md.

4. Choose the journey's target. Use Node unless the journey or change under test requires the Cloudflare runtime.

5. Start one disposable site:

   pnpm ux:site:start -- --target node --profile editorial-small
   

6. Keep the run ID, start URL, and run-data path from the command output. Never send the run-data file or API token to the tester.

Isolate the tester
