fix: retain crash ids and pointer-capture diagnostics - #239
Conversation
A worker that dies before writing a report now adds the heartbeat or log test id to run-level failed_ids, so last-failed can rerun it. Cancelled fail-fast siblings stay out of that set. Diagnostics finalize after pointer capture; a pointer-only failure keeps a privacy-safe snapshot. Co-authored-by: Nikola Perović <Fooftilly@users.noreply.github.com>

record_failed in run_worker’s failure handling. Keep the fallback ID for
diagnostic output.

- Line 58: Replace the fixed time.sleep(30) wait in this self-check with a
bounded cancellation check that the caller can observe, such as detecting
sibling completion or failed termination. Ensure the caller’s assertions verify
that outcome rather than passing solely because run_parallel returns the
expected failed-ID list.

Require the sentinel before triggering the failure.
If the sentinel does not appear within 15 seconds, this case still fails deliberately. A sibling that starts just afterward can create the sentinel before the caller checks the file, so the test can pass without proving that the sibling was active at failure time. Assert that the sentinel exists immediately after the wait and before assertEqual. As per path instructions, “For assertions, ... prefer observable state over arbitrary sleeps.”

Failure ids now come only from the heartbeat's current test id. The worker log stays diagnostic text, so a finished test that dies before its report is not rerun. The CI pointer job writes and uploads the same privacy-safe snapshot the local finalizer uses. Co-authored-by: Nikola Perović <Fooftilly@users.noreply.github.com>

Why
Follow-up to merged #235. Two post-merge defects in E2E failure diagnostics, plus the review fixes below. This does not reopen or amend #235. Do not merge until review is clear.
A. Crash-attributed tests stay in last-failed
When a worker dies before writing a report, only the heartbeat's current
test_idis added to run-levelfailed_ids(deduped) before diagnostics finalize and last-failed merge.A cleared heartbeat (
stopTest/ pre-reportclear_e2e_heartbeat) does not count. The worker log may still name a test that already passed; that line is diagnostic text only and is not stored as a failure. Intentionally cancelled--fail-fastsiblings are not recorded as failed tests. The 120s watchdog is unchanged.B. Pointer-capture failures keep a diagnostics snapshot
Local
tests/e2e/run.pystill finalizes diagnostics after the selected E2E tests and pointer capture. If tests pass and pointer capture fails, the file is:{"kind":"pointer-capture","failed_ids":[],"watchdog":false,"pointer_capture_returncode":<actual>}CI runs
tests/browser/pointer_capture.pyine2e-pointer, not throughmain(). That job now calls the samepersist_pointer_capture_failurewriter and uploads.tests/e2e-failure-diagnostics.jsonon failure. No screenshots, traces, or library content.Validation
