I want to be 🤖 a plugin to switch everything to test/sandbox mode

What if smartphones weren't a distraction but a solution for classrooms, students and administrators? Our I.P. seeks to allow mobile and other computer devices to become a trusted tool for educators, preventing cheating without violating student privacy concerns or locking down devices in case of a true emergency.

A single chokepoint that makes every external side-effect fail-closed, test-mode-by-default, and auditably suppressed — reaching the outside world requires an explicit literal opt-in. Composes a set of small safety primitives.

A default-safe bring-your-own-integration provider pattern: an abstract Provider over a generic Message, a registry whose test-mode gate returns a NullProvider before the registry is ever consulted, and typed auditable suppression instead of silent drops.

A default-safe transactional message dispatcher: test mode is on unless the literal 'false' opts into production, non-allowlisted recipients are redirected before any send, a format gate rejects malformed addresses, and the network send is an injectable transport (dry-run by default).
