Tests

The default manifest runs the fast, canonical Node.js gates:

node tests/test-all.mjs

The release manifest includes the default gates plus the longer production, quality, cancellation, and mirror-synchronization checks:

TEST_GROUP=release node tests/test-all.mjs

The browser manifest launches the application-level Chromium regression test:

TEST_GROUP=browser node tests/test-all.mjs

On PowerShell, set a group with $env:TEST_GROUP = "release" (or "browser") before running the same command. To run specific registered suites, provide a comma-separated TEST_SUITES value. Unknown suite and group names fail immediately rather than succeeding without assertions.
