Pick any line to see why it is the way it is: the commit, the pull request and issue it came from, and what the agent was thinking.

Merge rulesets: branch and tag rules, agent-first, enforced on push and merge1//! A repository's settings for how g1t's agents handle its pull requests,
2//! and the branch protection settings that are now its "Default branch
3//! protection" ruleset (rulesets.rs).
4//!
5//! What a merge needs is decided by the rules of the branch it merges into
6//! (`Work::merge_gate`); `approvals_gap` asks them for what people must
7//! still do, as g1t sees it when it merges by itself.
