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 40f9b0bee985 → HEAD ba83b15f86e9; 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.

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 40f9b0bee9 → HEAD ba83b15f86; benchmark order: head-first; workflow: success.

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.
