## The Problem

The nightly build `mutation` runs `pitest mutationCrapCheck mutationCrapCodeCharta`: the gate before the export.
When the gate fails, Gradle does not run the export, so the build has no code city and no structure views.
That happened on 2026-10-10: one mutant ended in a `MEMORY_ERROR`, the gate failed with an analysis error,
and `build/reports/codecharta/` stayed empty.
A failing gate is exactly when the code city helps most: it shows the methods to look at.

## Non-Goals

- No change of the limits, nor of the memory settings of PR#134 and PR#135.

## The Solution

- `.werkator.yml`: the build `mutation` runs `pitest mutationCrapCodeCharta mutationCrapCheck`, the export before the gate,
  as werkcrappit's guide for hsadmin-ng does.
- Version 1.38.13: only the nightly build changes.
