Problem

given() sends its caller as a project-relative file and line in the /agent/scope/given request, and the Keploy agent keeps it as the given value's Source (pkg/service/agent/given_proven.go in keploy/keploy). With spaces in the spec path, sourceOf() can skip the caller and use a lower Playwright frame. In the regression row on main, the request's source is node_modules/playwright/lib/worker/workerProcessEntry.js:1644 instead of test/fixtures/given caller with spaces.spec.ts:4.

The cause is the location regex, which stops at whitespace, and new URL(...).pathname, which leaves %20 in file:// paths.

Change

• Allow spaces in the location, and remove the at or at async prefix on frames with no function name.
• Decode file:// URLs with fileURLToPath(). A label it can't decode, such as an eval frame's file:///proj/a%2Fb.spec.ts, is skipped so given() doesn't throw.

Checked

• New row in playwright/test/rows.test.mjs: it runs a real spec with spaces in its filename against the local fake agent and checks the /agent/scope/given request. It fails on main with the Playwright path above and passes with this change.
• New sourceOf assertions cover encoded file:// paths, unnamed paths with spaces, at async paths with and without spaces, and an undecodable eval label. The Playwright row covers the spec filename with spaces.
• With playwright/src/index.ts from main, 2 Playwright tests fail: the new row and the sourceOf unit test.
• With this change: root build and tests, Jest and Playwright suites all pass on Node 22.23.4, with Playwright on headless Chromium.
• Not run: jest/e2e/lane.sh, the lane against a live Keploy agent, which needs a newer enterprise Keploy binary than I have.
