Drift not tracked

Drift is measured against the app's own repository, on the machine that runs the walk. This published copy has no checkout to compare against, so it reports what was captured and when — not how far the app has moved since.

Quality findings

2 to consider

  • No walkthrough video is attached

    Stills can explain states, but not timing, sequence, streaming, animation, or native gestures. Record at least one representative flow when the backend supports video, or leave the missing capability explicit in the run manifest.

  • 1 open issue found while walking

    interview-gym overflows on mobile (interview-gym). These were recorded during capture, not fixed — the walk observes the product, it doesn't repair it.

    live reconnaissance performed with Codex computer control · deterministic evidence recorded through the cross-runtime driver contract · production deployment SHA not exposed; no local checkout commit is claimed · invariants verified: retina, animationsFrozen, timeFrozen, contentful, consoleNetwork, video, realMobile, freshContext · feature "daily-learning-path" on desktop: 1 loading indicator(s) still visible after 15174ms — captures may show a loading state · feature "daily-learning-path" on mobile: 1 loading indicator(s) still visible after 15175ms — captures may show a loading state · surface "mobile": the page overflows horizontally — content is 508px wide on a 393px surface, so the layout viewport expanded to 508px and a real phone renders this zoomed out with a sideways scroll · feature "journey-interview-candidate" on desktop: 1 loading indicator(s) still visible after 15200ms — captures may show a loading state
