no automation pointer-flash artifact is present

Check id pointer-flash-keyframe-artifact

What an ordinary browser yields

No @keyframes rule named show-pointer-ani in any readable stylesheet. N/A when no same-origin sheet can be read (severity: warn).

What a detector infers

The only row on this page that works by recognising a specific string, which needs justifying because a name table is exactly what this audit refuses to build. The justification is that this is not a fingerprint of a browser, it is the leftover of a tool. The nodriver / SeleniumBase family ships a debug helper that paints a coloured dot over an element before clicking it, and it implements the animation by inserting a @keyframes rule named show-pointer-ani into the document's own first stylesheet. Measured on Chrome 150 against SeleniumBase 4.51.3: the injected div is removed when the animation ends - a MutationObserver catches both the insertion and the removal - but the keyframes rule is never cleaned up, so it is still in document.styleSheets long after the flash is invisible. No browser defines that name and no site has a reason to, so it can be asserted by name without the rot a browser-behaviour table would suffer; if the helper is ever renamed the row simply stops firing, which is the correct failure mode. Note the honest limit stated in the passing detail: the automatic flash-on-click was commented out upstream with the note that it may be getting detected, so the helper is now opt-in and this row passing means the artifact is absent, never that no driver is present.

How to resolve it

Stop calling the flash helper. It is a debugging aid with no effect on what the page does, and it writes a uniquely named rule into the document that outlives the animation it was created for. Nothing to fix for an ordinary visitor - no browser and no site defines this name.

Who builds this test

Clearcote is a browser built for fingerprint coherence

It is a Chromium fork, maintained by the same people who wrote this reference. It ships as a compiled browser rather than as a stealth script injected into someone else's — which is a description of how it is built, and is not an argument about how it behaves on this check.

This audit takes no position on how Clearcote scores on Automation surface checks, on this one, or anywhere else. It has no baseline corpus of other people's fingerprints to rank you against and no vendor scoreboard — nearly every check is self-referential, asking one browser the same question through two independent APIs and reporting whether both answers can be true at once. It runs identically on any browser, including ours. Run it on yours and read the result yourself.
