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 Page.navigate commands per binary.

Common ancestor 4b35bbc968 → HEAD 33b44c3309; benchmark order: head-first; workflow: success.

Recovery failures 0 0
Lifecycle order violations 0 0
Network order violations 0 0
Wall time 282.3 s 289.1 s

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.

Raw reports and per-navigation boundary samples: workflow run and full sequential-navigation-soak-results artifact.

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: 189 / 240 rows; 39 / 48 sites produced rows; 9 unexpected empty sites.

✅ Deterministic fixture contract is clean.

Common ancestor 4b35bbc96828 → HEAD 33b44c330927; benchmark order: head-first; workflow: success.

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 timelines

These 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.
