Empirically verified the full ZB.MOM.WW.MxGateway.Tests suite exits cleanly:
- macOS: 0 surviving testhost after a full run.
- windev (origin/main worktree): 0 new testhost and 0 new worker processes
after a full run, isolated by process StartTime.
Static audit confirms the prime-suspect fixtures already dispose deterministically
(WorkerClient cancels _stopCts + awaits its read/write/heartbeat tasks with a 5s
timeout; GatewaySession disposes the client; harness/E2E fixtures use await using).
Drop the stale 'leaves orphaned testhost processes' rationale from CLAUDE.md's
Source Update Workflow; keep filtered-run guidance as a speed guideline only.
Separately discovered (tracked in 00-tracking.md change log, NOT part of TST-08):
Windows-only temp-file-lock flakiness in ~4 full-host test classes (Sqlite
connection-pool retaining a temp .db handle; SelfSignedCertificateProvider's
fixed-name gw.pfx.tmp racing teardown) that macOS never surfaces.
