Maintainer Priorities

No specific priorities communicated yet.

Testing Opportunities Backlog

1. MSTest.Engine internal class coverage — TestArgumentsManager, TestFixtureManager, ThreadPoolTestNodeRunner are internal (~135+ LOC each). Would need InternalsVisibleTo or integration tests.
2. More Assert method coverage — Any remaining gaps in newer Assert overloads.
3. Analyzer edge cases (ongoing) — Continue systematic coverage of untested paths in MSTest.Analyzers.

Discovered Commands
