Year filter wait is ineffective
Medium Severity
After selecting the calendar year, waitForLoadState("domcontentloaded") does not wait for the Legistar table refresh. The page is already at that load state from goto, and year changes on this ASP.NET calendar often update via postback/AJAX without a new document load, so extraction can run against a stale year view.

Missing year outcome validation
Medium Severity
The new success check only requires a non-empty event list for CURRENT_YEAR. It never verifies that extracted date values actually contain that year, so a stale or mis-filtered calendar table can still pass.

This section replaces all historical E2E claims. Every executable entrypoint was freshly installed and invoked against the current PR head. No earlier run was counted as evidence.
There are 77 first-level language directories but 79 executable entrypoints: 68 Stagehand flows and 11 non-Stagehand flows. The previous description's “10 executable non-Stagehand flows” missed that both TypeScript and Python Playwright directories each contain two entrypoints.
Strict current result
f5a9cbdThe V3 side is a reconstructed behavioral baseline using the final V3 releases (
@browserbasehq/stagehand@3.7.1,stagehand==3.22.0). A literal clean install of several base-branch manifests is no longer reproducible because they usedlatestor open-ended constraints that now resolve V4.Legend: FIXED means the fresh pre-fix V4 run failed and the exact post-fix rerun passed. BLOCKED is not counted as a pass.
