Sequential Navigation Soak A/BOne browser process, one target, and one CDP session navigate CSDN → SegmentFault → Huaban → example.com repeatedly. This run issued 200 Common ancestor Session resilience
A public-page failure is reported separately from an unrecoverable session. The soak requires all navigation attempts, zero failed recovery, zero lifecycle/network ordering violations, and complete resource evidence. Process-tree memory
HEAD memory by 50-navigation quarter
Raw reports and per-navigation boundary samples: workflow run and full Public-site timing and memory are observational. Use the A/B deltas and trend shape as evidence, not as a deterministic performance threshold. |
Spider Bench A/B✅ All benchmark browser service runs completed; results are informational. Public HEAD: 184 / 240 rows; 38 / 48 sites produced rows; 10 unexpected empty sites. ✅ Deterministic fixture contract is clean. Common ancestor Public 48-site run · informational
Public-site content, timing, and memory are noisy. This single A/B run reports evidence only; site outcome counts explain missing rows without treating them as a deterministic regression. CPU and memory timelinesThese are bounded 40-point views of the same complete process-tree samples used by the HTML report. CPU uses 100% per occupied logical core; memory lines are RSS first and PSS second when complete PSS samples are available. Basexychart-beta

Expose Document.fullscreen and Document/ShadowRoot.fullscreenElement as native readonly attributes with WebIDL receiver checks and LegacyLenientSetter behavior. Preserve main fullscreenEnabled=false. Exercise all 881 getter/setter matrix cases across same/cross realms and live, windowless, parsed and new Documents; author and revoked Proxies must reject without traps. Depends on the Node native backing foundation PR.
Depends on #1861.
