The Problem

werkcrappit 0.25.0 writes two new pages beside the code city of the nightly mutation build: structure.html, one level diagram per package with cycles, complexity and cohesion, and matrix.html, a dependency matrix that opens package by package. Werkator still uses werkcrappit 0.16.4, which writes neither. RFC 0003 names Werkator as the first project to try the pages on, a Kotlin project, before hsadmin-ng.

Non-Goals

• No change of Werkator itself, nor of its limits: maxMutationCrap = 15 and red from 12 stay.
• No gate on cohesion or coupling; werkcrappit's maxLcom4 and maxEfferentCoupling stay unset.

The Solution

• build.gradle.kts takes the Gradle plugin de.javagil.werkcrappit 0.25.0 instead of 0.16.4; it brings werkcrappit-pit of the same version.
• The nightly build mutation runs mutationCrapCodeCharta already, so its artifact build/reports/codecharta/ gets structure.html and matrix.html; index.html links both.
• Werkator serves artifacts with Content-Security-Policy: sandbox allow-scripts, so the inline scripts of the pages run.
• Version 1.38.1, as only the tooling of the nightly build changes.
