Sequential Navigation Soak A/B✅ HEAD completed the 200-navigation resilience and memory observation. One 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

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: 179 / 240 rows; 37 / 48 sites produced rows; 11 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 uses 100% per occupied logical core; memory lines are RSS first and PSS second when complete PSS samples are available. Basexychart-beta

Closing after the consolidation audit. Inferring a likely navigation from credentialed XHR/fetch activity is a site-driven heuristic and is intentionally excluded from #1501. Explicit completion contracts remain the correct interface. |

A page can reach Load while the main document still owns a credentialed Fetch/XHR callback that immediately hands off to a top-level navigation. The CLI currently freezes that bootstrap document, so native Markdown can be empty even though the page is completing its own same-document authentication flow.
This change reuses the renderer’s typed, owner-bound navigation handoff. At Load, it observes only explicit credentials-including Window Fetch/XHR requests owned by the current main document. It waits within the existing bounded navigation window, finishes as soon as that request chain settles, and follows a successor navigation through the existing owner state machine. Ordinary requests, workers, resource loads, long timers, polling, and URL-specific rules are excluded.
Behavior tests cover a credentialed bootstrap callback that performs a same-origin top-level replacement. A negative control verifies that an unrelated four-second request and five-second timer do not delay the result. The tests run through the repository CI.
