Unlike classic branch protection, where exactly one rule matched a branch and the most specific pattern won, repository rulesets and organization rulesets that target the same ref are all evaluated together and their rules are unioned. If any applicable ruleset requires a pull request, pull requests are required, and there is no way to write a narrower ruleset that relaxes a broader one.

This matters when an organization ruleset and a repository ruleset both target the default branch: the repository owner cannot loosen the org rule, only add to it. It also means classic branch protection and rulesets coexist and both apply.

To see what actually applies to a ref, use the ref rules endpoint of the REST API rather than reasoning about the UI. Ruleset target patterns support fnmatch syntax plus the special names ~DEFAULT_BRANCH and ~ALL, which is the reliable way to target the default branch without hardcoding 'main'. Bypass actors are the only escape hatch, and they are configured per ruleset.
