The project is deployed as a Cloudflare Worker, so the test harness now uses Cloudflare's Vitest pool instead of Bun's built-in runner. Existing tests were migrated to Vitest, utility crypto/CORS coverage was added for issue #2, and a small Worker runtime smoke test proves wrangler vars and request handling load through the Cloudflare test environment.

Constraint: Cloudflare Workers runtime APIs and wrangler bindings should be exercised through @cloudflare/vitest-pool-workers

Rejected: Keep Bun's built-in test runner as primary | it does not exercise Workers runtime bindings and had incompatible module mock behavior locally

Rejected: Maintain parallel Bun and Vitest suites | unnecessary duplicate maintenance for this small Worker

Confidence: high

Scope-risk: moderate

Directive: Keep docs/superpowers artifacts out of product commits unless the user explicitly asks to version workflow docs

Tested: bun run test (10 files, 106 tests); git diff --check; no bun:test/mock.module/vi.module leftovers

Not-tested: GitHub Actions execution on remote runner
