The hosted Settings failure stalls during bootstrap without enough evidence to separate server delay from browser scheduling. Attach redacted, bounded cookie-session HTTP timings alongside browser response timings without weakening readiness or layout assertions. Change-source: pulse-maintainer

# Settings bootstrap timing diagnostic
|
|
|
|
The desktop-to-390px Settings test attaches `bootstrap-paired-timing` to its
|
|
Playwright report, including on assertion failure. It issues at most one extra
|
|
GET each for summary and runtime capabilities, when the browser first requests
|
|
that path. The HTTP client shares the test's cookie session but not the browser's
|
|
network scheduler. Redirect following is disabled; each probe has a five-second
|
|
limit. No readiness condition, capability requirement or assertion is relaxed.
|
|
|
|
`started` is host epoch milliseconds. Browser duration ends at response headers;
|
|
HTTP duration includes response receipt. Null browser status/duration is censored,
|
|
not a server error. Null HTTP status is a transport failure/timeout without a
|
|
received response; the exception is deliberately not retained. Reports exclude
|
|
headers, credentials, query strings and payloads.
|
|
|
|
For the next hosted observation, retain this attachment, the browser trace and
|
|
application startup timestamps from the same job/source. Compare overlapping
|
|
summary/capabilities requests; a quick HTTP response with stalled browser narrows
|
|
the question towards browser scheduling, while both delayed supports further
|
|
server/startup measurement. Neither proves a particular lock is responsible.
|
|
Extra probes can warm caches or contend themselves, so do not claim a controlled
|
|
effect size or historical causality. Do not select favourable repeats, widen the
|
|
assertion timeout, or treat a successful diagnostic as probation promotion.
