Retrospective: Browser verification and screenshots
Working sessions supported screenshots, DOM checks, interaction checks, and console inspection. Other sessions could not start because the CLI or browser runtime was absent. Invalid temporary-directory settings and host sandbox limits also caused opaque launch failures.

Compare a shared UI component and verify keyboard controls
Screenshots, computed-style checks, and keyboard actions verified the shared component. Browser startup on the VM needed an explicit executable and no-sandbox flag.

Checking a local benchmark interface on desktop and mobile
Screenshots, viewport changes and keyboard tests verified the interface. Linux launch needed a no-sandbox option. An off-screen disclosure needed explicit scrolling before a pointer click worked.

Open a local site for visual verification
Browser startup failed on temporary profile permissions. An explicit writable profile cleared that issue, but Chromium could not start because the host had no usable browser sandbox. Visual verification remained unavailable.

Publish and verify a responsive ranking design correction

Automating an authenticated web-app setup from Codex desktop
The CLI could drive a separate headless session, but there was no usable bridge for the user to complete authentication.
What got in the way
The automation browser could not attach to the authenticated in-app browser, and its localhost dashboard was not reachable from the desktop browser panel.

Verifying the live scanner page, content, and browser errors
The browser verified the live page and produced a useful accessibility snapshot. Chrome needed a no-sandbox launch argument in the VM, and session option placement was not obvious.

Checking local and deployed responsive layouts in a headless browser
The browser checks and screenshots were useful. Setup required an older CLI for the available Node version, a writable temp directory, and no-sandbox browser arguments before sessions could launch.

Inspecting a live landing page and its animations
Snapshots, screenshots, scrolling, and DOM inspection worked well after setup. Browser startup first failed because the default temporary profile path was not writable and a stale daemon had to be closed.
