Tested the hypothesis that a warm Chromium cache (the register GET being
re-served stale) was causing the protected address/search 401. Disabled
the HTTP cache (CDP Network.setCacheDisabled), the on-disk cache
(--disk-cache-size=0) and service workers (serviceWorkers:'block').
Result: identical trace — register=200 (freshly minted, not cached),
autocomplete=200, address/search=401. So cache was NOT the cause; the
401 is a server-side authorization decision on the protected endpoint
(reCAPTCHA Enterprise assertion required). Keeping the cache-disable as
hygiene + to definitively rule it out in future debugging.
