 ## Change classes (§3.3 of the design)
 
 | class | trigger paths (examples) | PR tier |

-| 0 — prose | , docs/, comments-only changes | nothing, or markdown lint only |
-| 1 — config/data |  non-build,  (non-workflow) | syntax parse + lint of changed files |

 | 2 — package source (default) | one package's src + tests | lint/format + typecheck/syntax of affected packages + affected unit tests |
-| 3 — elevated | lockfiles, / roots, /, build definitions (), , shared/core libraries | class 2 + compile check of affected packages |

 Default when a change spans classes: the highest class wins. The
 policy ships conservative (more class 3) and loosens as the
-main-breakage rate (issues labelled ) proves out.
+main-breakage rate (issues labelled `main-broken`) proves out.
