See the agent contract before you update.

Choose one of 50 plugin-version pairs already booted in an isolated WordPress runtime. The receipt shows whether registered abilities appeared, disappeared or changed — and abstains when the runtime evidence is incomplete.

Measured plugin update

This does not install the plugin, inspect your site, or say an update is safe. Pairs outside this list are not measured in the first beta.

What this adds to staging and rollback

Existing update tools can back up, test and roll back a site. This preflight answers a narrower earlier question: did the WordPress Ability contract visible to agents change between these exact versions? Keep your normal staging, backup and rollback process whatever this receipt says.
