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
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

Navigation tests can accept a load event left over from an earlier popup navigation. Layout assertions also depend on the host's monospace font, and fetch tests compare complete responses whose Date headers change between requests.
Wait for the requested navigation's loader-specific lifecycle event, register the existing bundled Ahem font for the two layout tests, and give the local HTTP fixture a fixed Date header. The font registration helper is compiled only for tests. Production fetching, rendering and Markdown conversion are unchanged.
The Ahem layout expectations were checked against Chromium across all 120 combinations in the two tests. This change is independent of the content-export work in #919 and its split PRs #1334–#1337.
