Goal

Add TransportMode enum and parametric scenario runner scaffolding to packages/Harness/ to support UQ-5 dual-mode execution.

Scope

  • TransportMode.{inProcessActor, jsonRoundTripWebView}
  • ScenarioRunner.run(_:in:) invokes a scenario closure once per mode
  • Reuses existing RealWKWebViewIntegrationTests infrastructure as the JSON substrate
  • Scaffolding stub only (no real scenarios yet)

Files

  • packages/Harness/Sources/Harness/TransportMode.swift (new)
  • packages/Harness/Sources/Harness/ScenarioRunner.swift (new)

Acceptance

  • swift test --package-path packages/Harness green
  • Stub scenario executes in both modes
  • No @testable import from production targets (UQ-5 mandate harness composes without testable)

Test

A stub scenario ping → pong runs in both .inProcessActor and .jsonRoundTripWebView modes.
