## 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.
