Summary

Add pnpm scenario: the real Hono API and built renderer run against the simulator using disposable ports, configuration and cache. Terminal controls drive repeatable upstream transitions without using the user's credentials.

Validation

Local stack head 1d1d925 passed:

• pnpm typecheck, pnpm test (171 unit/integration tests)
• pnpm lint (including four boundary checks), pnpm fmt:check
• pnpm test:e2e (five Chromium scenarios)
• pnpm test:desktop (packaged macOS arm64 launch, restart, SQLite and shutdown)

These are local results; GitHub checks are reported separately.

How to review

Start with harness/src/runtime.ts for isolation and cleanup, then run.ts for the controls. Verified the queued → failure → outage → recovery command sequence.
