Default reporter "html" opens the report via `open --wait-apps` on
macOS, which blocks until the launched browser exits. When Playwright
is driven by an agent (no interactive user to close the window), the
shell never returns — burning the calling process until something
else kills it.
Switch both configs to `[["html", { open: "never" }]]` so the report
is still generated but not auto-opened.

Summary
Change both
playwright.config.tsfiles (packages/runtime,packages/wasi) fromreporter: "html"toreporter: [["html", { open: "never" }]].Why
On macOS the default
htmlreporter auto-opens the report by spawningopen --wait-apps <url>, which blocks until the launched browser exits. For anyone running Playwright non-interactively (CI runners withoutCI=1, agent-driven shells, background tooling), the invoking shell never returns — the process just hangs on theopen --wait-appschild.With
open: "never"the report is still generated on disk and can be viewed manually vianpx playwright show-report; Playwright just won't auto-launch a browser on completion.Test plan
npx playwright testinpackages/wasi— run finishes, shell returns, no browser auto-launched.npx playwright show-report— report still renders.packages/runtime.
