Comment/XML-doc changes only: - add summaries to ~10k test methods, fixtures, fakes and helpers (+ <param> on theories, <returns> on async Task methods, <inheritdoc/> on interface implementations the checker can resolve) - strip ~2.6k project-tracking references (WP*, P*-*, row-NN, Task N, #NN, Component-0NN) from comments, keeping the explanatory text; reword false positives in comments only - real docs on fakes implementing BCL/library interfaces (IDisposable, ILogger, IOptionsMonitor, IAsyncLifetime) - reword the last 5 src/ false positives (CWE-1236, failures-1, year-0001, M365) Only non-comment edits: four one-line nested classes split across lines so members can carry docs. Build 0 errors / 0 warnings.
