Problem

stryker-config.json lists four entries under test-projects, one of which (tests/NetEvolve.ProjectBuilders.Tests.Integration) is not part of ProjectBuilders.slnx. The key is misleading dead config. The latest successful mutation run analyses exactly the three slnx test projects (Tests.Unit, XUnit.Tests.Integration, TUnit.Tests.Integration) and never mentions the orphan.

Root cause

The config uses "solution": "ProjectBuilders.slnx". In Stryker 5.0.0 solution mode, test projects are discovered from the solution and test-projects has no effect (read from the 5.0.0 source and corroborated by the existing log). The list is therefore redundant, and one entry is stale.

Change

Remove the test-projects array from stryker-config.json (6 lines deleted). The orphan project itself and the README references to it are intentionally left for a separate change.

Before / After

Run: https://github.com/dailydevops/projectbuilders/actions/runs/40809851770 (workflow_dispatch on this branch) vs. the latest successful run on main.

metric	before	after
mutation score	74.73%	74.73%
mutants created	603	603
compile errors	27	27
no coverage	27	27
survived (only covered by failing tests)	40	40
ignored (block already covered)	109	109
killed / survived / timeout	349 / 51 / 0	349 / 51 / 0
"N tests are failing" warnings	16, 14, 30	16, 14, 30
run duration	n/a	about 11 min
test-projects entries	4 (1 stale)	0

As expected, nothing changed in the Stryker run; this is a pure config cleanup.

Risk / what this does not change

No behaviour change expected in solution mode. Does not delete the empty Tests.Integration project and does not touch the README. No score improvement is claimed.
