Subject: [PATCH 04/23] test: wait for backend readiness before global setup

The CI control failed with "Cannot POST /rest/e2e/reset".
The favicon check allowed setup to start before routes were ready.
Change to use the readiness endpoint to wait for initialization.

The Endform trace showed frontend startup progressing after
the 10-second navigation timeout.

Increase only remote navigation to 30 seconds to test whether
startup completes. Keep control timing and retries unchanged.

The session trace still records 1,407 request continuations.
A catch-all handler adds trace headers to browser requests.

Remove that handler only in the Endform experiment.
Keep targeted mocks and Playwright traces.
Use the next run to measure its cost.

Subject: [PATCH 20/23] test: restore tracing after the routing experiment

The trace confirms catch-all routing was removed.
Request continuations fell from 1,407 to zero.
Suite duration changed only from 8.2 to 8.1 minutes.

Remove the diagnostic override.
Restore normal tracing because no material speed gain was shown.

Subject: [PATCH 21/23] test: measure video recording overhead

Page-load traces show delays beyond the main asset transfers.
Disable video recording for both experiment runners.
Keep traces, screenshots, tests, concurrency and timeouts unchanged.

Use the next run to measure recording overhead.
Preserve video recording by default outside the experiment.

Disabling video showed no Endform runtime improvement.
Remove the experimental switch and restore recording.
Preserve debugging evidence while investigating page-load delays.

Subject: [PATCH 23/23] test: record backend capacity during runner comparisons

Capture host and process resource usage during the test step.
Record the backend listener PID to identify n8n usage.
Preserve measurements with the existing run artifacts.

Keep concurrency at four to establish a scaling baseline.
