Pull request overview
Adds a Stryker.NET configuration file so mutation testing can run for this repository (targeting a single TFM) under the existing Stryker workflow setup.
Changes:
- Add
stryker-config.jsonthat points Stryker at the library project and the unit test project. - Configure mutation testing to run on
net10.0. - Set mutation score thresholds with
break: 0to avoid failing CI while establishing a baseline.

stryker-config.jsonso Stryker.NET mutation testing actually runs against this repo once the canonical.github/workflows/stryker.yamllands.target-framework: net10.0(mutation runs one TFM at a time)thresholds.break: 0(keep CI green while baseline establishes)Pattern lifted from IComparable-Extensions PR #136 — 100% mutation score on the v1.1.1 test surface.
Ordering note
The earlier description claimed the canonical
stryker.yamlwas "already shipped via the T3 fanout" — that was true in IComparable-Extensions but not in this repo. PR #153 (the standalone T3 workflow PR) and PR #151 (the canonical-protected umbrella) were both closed unmerged. The workflow currently lives onvNextand will land onmainvia the in-flight Release PR (#166).This config is therefore a no-op on main until #166 merges, after which the weekly mutation run starts producing scores. No CI break in the meantime — the config sits as plain data until the workflow looks for it.
