The Windows process launcher no longer needs Bash/PowerShell mediation, and the event-source tests now exercise CLI boundaries through an injectable executor instead of generated scripts. This keeps production behavior on real external commands while letting tests model long-running process streams and kill semantics in Dart.
Constraint: Tests must not mock CLIs by writing generated Dart or shell scripts and executing them.
Rejected: Use generated Dart script fixtures | still depends on subprocess execution for mocks.
Rejected: Use only mocktail mocks for process handles | stream, kill, and exit behavior are clearer as a small stateful fake.
Confidence: high
Scope-risk: moderate
Directive: Keep long-running CLI test behavior behind ExternalCommandExecutor rather than reintroducing script fixtures.
Tested: dart analyze; dart run tool\\validate_gherkin_test_format.dart; dart test
Not-tested: Real gh/gosmee webhook forwarding against live services
