The source code implements exactly what the extension claims: listens to chrome.history.onVisited and chrome.downloads.onChanged, checks against user-defined keywords stored in chrome.storage.sync, and deletes matching entries locally — no data is sent externally. The two network calls flagged by the ML model (one POST and one GET to [domain withheld]) are part of the ExtensionPay payment library ([domain withheld]), a legitimate freemium payment service for Chrome extensions; crucially, the extension ID used is 'auto-keyword-history-deleter' and the publisher is Glen Chiacchieri (), who is also the author of the ExtPay library itself. CWS-disclosed data categories ('Personally identifiable information', 'Financial and payment information') precisely match the ExtensionPay integration, making these network calls benign by disclosure. The 290 js_exclamation hits, innerHTML, and appendChild counts are entirely attributable to standard Rollup + Svelte + webextension-polyfill build artifacts, not obfuscation. The permhash cluster showing flagged is a corroborating ML signal that is contradicted by the actual code; it likely reflects the extension's removal from the store being backfilled as a flag, not verified malicious behavior.
