Re-quarantines Microsoft.AspNetCore.SignalR.Client.Tests.TestServerTests.WebSocketsWorks, which was unquarantined in #67261 but has started failing again on the main branch.

Failures were observed in 3 separate main-branch CI builds after the unquarantine:

  • Build 1474974 (2026-06-22)
  • Build 1477119 (2026-06-23)
  • Build 1478270 (2026-06-23)

All failures occurred in the batch_3--net11.0 Helix work item. The original tracking issue is #65914.

Changes

  • src/SignalR/clients/csharp/Client/test/UnitTests/TestServerTests.cs: Re-added [QuarantinedTest("https://github.com/dotnet/aspnetcore/issues/65914")] attribute to WebSocketsWorks.

Don't merge, the test may have been fixed around June 23. I'll investigate why the workflow didn't skip this on Monday

Two recent misbehaviors (run 28656097334): PR dotnet#67577 tried to unquarantine
SetsTlsHandshakeFeatureForHttps despite issue dotnet#49306 carrying the re-quarantine
label, and PR dotnet#67576 re-quarantined WebSocketsWorks despite maintainer "do not
quarantine" comments on the already-rejected dotnet#67443/dotnet#67415.

Root causes:
- The unquarantine re-quarantine check only parsed merged-PR diffs and left the
  match/exclude decision to the model; it never consulted the re-quarantine
  issue label the maintainer set.
- The closed-PR comment check relied on MCP search_pull_requests, whose DIFC
  filter silently drops the workflow's own app/github-actions-authored PRs, so
  the maintainer comments were never seen.

Fixes (deterministic pre-activation steps + injected data):
- Fetch re-quarantine issue numbers; block unquarantine of any test whose
  tracking issue is labeled re-quarantine (authoritative, exact match).
- Fetch closed-but-unmerged [test-quarantine] PRs + comments with a full token,
  bypassing the DIFC filter; the closed-PR check now uses this instead of MCP.

Recompiled lockfile with gh-aw CLI v0.81.6 (setup action v0.80.9 -> v0.81.6).
