Content Security Policy is enforced
The data: script is blocked.
What a detector infers
The audit excludes data: scripts. Execution despite script-src is direct CSP-bypass behavior.
How to resolve it
Do not enable Page.setBypassCSP or bypassCSP.

- No console preview enumerated a prototype-chain Proxy
console-preview-proxy-trapDevTools has to look inside an object to show it to you, and in JavaScript looking inside an object is an observable act. - No Puppeteer / Playwright sourceURL marker
sourceurl-leakPuppeteer and Playwright evaluation labels can appear in main-world Error stacks. - No controller code crossed the main-world canary
main-world-executionAn early DOM canary records main-world calls, but page code and extensions can also call it, so this is contextual. - No exposed Puppeteer / Playwright binding
exposed-binding-leaksExposed functions leave Playwright/Puppeteer registries, prefixes, source text, or __installed markers. - the browser will not resolve a filesystem path the page invented

chrome-native-stubsWhere the previous check asks whether window.chrome exists, this one asks whether its members are genuine.
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.
