CyberGuard: consent-compliance audit and browser-extension evaluation — data, selectors, and code

Companion dataset and code for the manuscript "Client-Side Privacy Enforcement for Digital Consumers: A Browser Extension Against Consent-Independent Web Tracking" (prepared for submission to Electronics, MDPI). Contains: the audit campaign (dual-persona crawl, 100 domains, 23 June 2026) and evaluation campaign (unprotected vs. CyberGuard, 100 domains, 26 June 2026) datasets; the four consent-interaction selector lists; the Playwright crawler harness; the CyberGuard extension source (Manifest V3); and two reproduction scripts, one that recomputes and asserts every headline statistic in the manuscript and one that regenerates the figures. See README.md for the data dictionary, methodology, and known caveats.
