The rules behind the product, on the record
Every number Two Shores shows comes from a versioned rule module. This page is the public record: the current version and review status of each module, and every content update a version change has prompted.
Content updates
When a rule module changes, the playbook sections built on it are revised and the update is recorded here. Playbook owners receive the same note by email.
No updates yet. The first entry appears the first time a rule changes after launch, which is the whole point of this page.
Rule modules
The deterministic modules that produce every figure on the site. “Pending independent review” means a qualified human reviewer has not yet signed off on the module’s substance; we say so rather than imply otherwise.
