What does this change?
Adds puzzles as a supported A/B test team prefix and registers a new server-side experiment for the Puzzles Hub:
The initial audience is intentionally set to zero so the experiment can be validated through forced opt-in before enabling an organic rollout.
How to test
After deploying the A/B testing configuration, force the variant with:
https://www.theguardian.com/ab-tests/opt-in/puzzles-new-hub:variant
Force the control group with:
https://www.theguardian.com/ab-tests/opt-in/puzzles-new-hub:control
Opt out with:
https://www.theguardian.com/ab-tests/opt-out/puzzles-new-hub
Validation
Follow-up work
Frontend and DCR will consume puzzles-new-hub from serverSideABTests to place the new Puzzles Hub routes, navigation and components behind the experiment.
The organic audience will remain at 0% until the control and variant experiences have been deployed and validated.
