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.
Add ParkedMessagesActionTests with three facts: Query disabled until site selected, Clear disabled until filter set (then re-disabled after clear), and a tolerant bulk Retry/Discard bar reveal when parked rows happen to be present. Distinct from the existing render-without-hang test — gating facts are deterministic; row-dependent fact early-returns gracefully in unseedable environments.
Guards against the Akka singleton Ask hang regression: asserts all nine KPI
tiles on /monitoring/health resolve to numeric values and never show the
em-dash degrade placeholder (—). Covers Notification Outbox, Audit, and
Site Call tile groups. Selector disambiguation: Outbox tiles are div.card,
Site Call tiles are button.card — prevents strict-mode collisions on the
shared "Stuck" and "Parked" labels.
