Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
source-diff obfuscated-file:lib/vite/traceViewer/index.BCnMPevh.js AI (source-diff): Vite-bundled trace viewer entry; standard minified build output. ai
source-diff net-exec-file:lib/vite/traceViewer/assets/defaultSettingsView-D31xz8zv.js AI (source-diff): Bundled React app with fetch for modulepreload; not malicious network+exec. ai
source-diff obfuscated-file:lib/vite/traceViewer/assets/defaultSettingsView-D31xz8zv.js AI (source-diff): Vite-bundled React UI; standard minified build output for this package. ai
source-diff obfuscated-file:lib/vite/traceViewer/assets/codeMirrorModule-Ds_H_9Yq.js AI (source-diff): Vite-bundled CodeMirror; standard minified build output for this package. ai
source-diff obfuscated-file:lib/vite/recorder/assets/codeMirrorModule-BHYmBp6h.js AI (source-diff): Vite-bundled CodeMirror; standard minified build output for this package. ai
source-diff obfuscated-file:lib/vite/traceViewer/uiMode.C2Efnu2P.js AI (source-diff): Vite-bundled UI mode entry; standard minified build output. ai
source-diff obfuscated-file:lib/vite/dashboard/assets/index-DpEq2p62.js AI (source-diff): Vite-bundled React UI; standard minified build output for this package. ai
source-diff obfuscated-file:lib/vite/recorder/assets/index-DA10QRaq.js AI (source-diff): Vite-bundled React UI; standard minified build output for this package. ai
npm-metadata suspicious-initial-version AI (npm-metadata): 0.0.0 is the legitimate namespace-reservation stub for the canonical Playwright package, published 6+ years ago with 50.7M weekly downloads across 5458 versions. ai
provenance no-provenance AI (provenance): playwright-core is an established Microsoft package predating Sigstore provenance adoption on npm; absence of attestation is expected for this version. ai
semgrep semgrep:shady-links-raw-ip AI (semgrep): Constructs a localhost URL (127.0.0.1) for an internal HTTP server — standard practice for Playwright's local browser automation server. ai
install-scripts install-script:install AI (install-scripts): playwright-core's install script downloads browser binaries — this is the package's documented and expected install flow, stable across all versions. ai
semgrep semgrep:http-module-request AI (semgrep): HTTP requests in browserFetcher.js are used to download browser binaries from CDN — core functionality of this browser automation package, not exfiltration. ai
source-diff obfuscated-file:lib/vite/traceViewer/index.Dtstcb7U.js AI (source-diff): Vite-bundled frontend asset for Playwright Trace Viewer UI. Hash-suffixed filenames are standard Vite content-hash output. Code is minified React/UI code, not malicious obfuscation. ai
bogus-package bogus-package AI (bogus-package): playwright-core is a large Microsoft framework; no keywords and no declared deps are structural choices, not spam indicators. README is at playwright.dev. ai
npm-metadata bundled-binaries AI (npm-metadata): PrintDeps.exe is a documented Playwright utility for inspecting Windows DLL dependencies during browser binary management. Legitimate and stable across versions. ai
semgrep semgrep:hex-decode AI (semgrep): Hex decode in utilsBundleImpl is part of bundled dotenv/debug string parsing logic, not malicious payload handling. False positive for this package. ai
semgrep semgrep:child-process-spawn AI (semgrep): Spawning child processes is core to Playwright's browser automation functionality. Confirmed legitimate use in debug mode launcher. ai
source-diff obfuscated-file:lib/vite/traceViewer/assets/codeMirrorModule-DS0FLvoc.js AI (source-diff): Vite-bundled frontend asset for Playwright's Trace Viewer UI. Minified CodeMirror editor code — expected for this package. ai
semgrep semgrep:api-obfuscation-reflect AI (semgrep): Reflect.get() in bundled zod library — standard JS metaprogramming, not evasion. ai
semgrep semgrep:env-bulk-read AI (semgrep): Environment enumeration in a bundled utility — standard config/logging behavior in this framework. ai
semgrep semgrep:dynamic-require AI (semgrep): Dynamic require used to load package.json from browser reference directories — benign metadata reading. ai
semgrep semgrep:base64-decode AI (semgrep): Base64 decoding used for WebSocket message handling between browser page and Playwright server — expected protocol behavior. ai
semgrep semgrep:new-function-constructor AI (semgrep): Used in javascript.js for JS expression validation before evaluation — legitimate use in a browser automation tool. ai
semgrep semgrep:env-spread AI (semgrep): Spreading process.env when spawning browser child processes is standard and expected for a browser automation framework. ai
semgrep semgrep:child-process-import AI (semgrep): Playwright-core must launch browser processes via child_process — this is core functionality, not malicious. ai
source-diff obfuscated-file:lib/vite/traceViewer/uiMode.Vipi55dB.js AI (source-diff): Vite-bundled UI mode asset for Playwright's Trace Viewer. Minification is expected for browser-targeted build output. ai
source-diff obfuscated-file:lib/vite/traceViewer/index.C5466mMT.js AI (source-diff): Vite-bundled Trace Viewer entry point. Minified output is expected for browser-targeted assets in this package. ai
source-diff net-exec-file:lib/vite/traceViewer/assets/defaultSettingsView-GTWI-W_B.js AI (source-diff): Network calls are Vite modulepreload polyfill (fetch) and React rendering — standard frontend bundle behavior, not dropper malware. ai
source-diff obfuscated-file:lib/vite/traceViewer/assets/defaultSettingsView-GTWI-W_B.js AI (source-diff): Vite-bundled React frontend asset for Playwright's Trace Viewer UI. Minification is expected for browser-targeted build output. ai
