Enum MergeStyle 

pub enum MergeStyle {
    Merge,
    Squash,
    Rebase,
}

How the winning branch is attached to the base branch: what mode = "local" runs, and what mode = "none"’s printed guidance tells the operator to run by hand.

Read from configuration rather than asked of the repository at run time (e.g. gh api repos/{owner}/{repo}/rulesets) for two reasons: it keeps mode = "none"’s guidance a pure function of RunState, assertable in a unit test the same way land::decide is kept pure (see that module’s doc), and it works for a base branch that is not hosted on GitHub, or not reachable at all, at the moment the report is rendered. An operator whose base branch enforces a ruleset already knows what it allows; declaring it once here is cheaper than magi re-discovering it, with a network call, on every render.

Variants

Merge

git merge --no-ff: every candidate commit lands, plus a merge commit that records the merge as its own event in history. Rejected by a base branch whose ruleset requires linear history or forbids merge commits outright.

Squash

git merge --squash followed by a commit under an explicit message: every candidate commit folds into one, and none of the candidate’s own placeholder subjects (magi: candidate A (uncommitted work)) reach the base branch. No merge commit, so this satisfies a linear- history ruleset.

Rebase

A fast-forward-only merge: every candidate commit lands verbatim, in order, with no merge commit. Only succeeds because the winner was already rebased onto the tracked base tip before this runs (see Runner::sync_to_base) — equivalent to GitHub’s “rebase and merge” once that has happened.
