SBL-CORR-2026-003: The X pixel decoder treated any populated sale amount or order quantity as Purchase, including zero. The Purchase label in these reports is unsupported and must not be used as evidence of a purchase. The underlying X pixel requests remain observations. Consult earlier clarification events for input-probe and policy limitations.

Consent Comparison

Accept-all attempt and Reject-all attempt: two visits, no comparable metric delta

Accept-all attempt: 15,914msReject-all attempt: 16,123ms
These two visits do not support a side-by-side comparison, so no deltas are shown.
  • The "Accept-all attempt" visit recorded no accept-all control activation, so it cannot be shown to reflect that choice.
  • The "Reject-all attempt" visit recorded no reject-all control activation, so it cannot be shown to reflect that choice.

Each visit's own evidence still stands: use the “Evidence shown” switcher below to inspect either visit's tables, and both visits are in the downloaded JSON.

Measurement limits

9 conditions affect how this evidence reads

This report

  • Consent comparison runs are sequential automated visits: one asked to click the banner's accept-all choice, one asked to click reject-all (first layer only). A run where no control was clicked reflects the pre-consent state instead; see each run's consent note. Differences can also come from timing, experiments, cache state, or bot detection.

Both visits

  • Each visit in this report is one automated, headless Chromium visit from a fixed en-US / UTC profile, with no scrolling or clicking except one scripted choice on the cookie/consent banner (disclosed below). Sites can behave differently for real users, browsers, regions, accounts, or network locations.
  • Counts are a lower bound: trackers that load only after further interaction, and any activity inside Web or Service Workers, are not observed. Service labels use a US-biased hand-curated catalog, so regional services may be under-labeled. Cookie and storage figures are an end-of-visit snapshot.
  • The page did not reach network idle before the scan window ended.
  • This scan typed a synthetic test value into 3 form fields (never submitting the form) to test whether typed input is captured and sent to third parties. The value is synthetic and is not stored.
  • Resolved 1 first-party subdomain that are CNAME aliases for third-party trackers (CNAME cloaking), which request-URL matching alone would miss.
  • Read the site's privacy policy (https://www.webmd.com/{seg}/{seg}) and compared its text against this visit's observed behavior. Policy checks are an automated text match with the matched sentences quoted, not a legal reading.

Accept-all attempt visit only

  • This visit was asked to choose "Accept all" on a cookie/consent banner, but no recognizable control was found (the banner may not be shown to this scanner's location, the choice may sit behind a settings layer, or the control is not in the catalog). Results reflect the pre-consent state.

Reject-all attempt visit only

  • This visit was asked to choose "Reject all" on a cookie/consent banner, but no recognizable control was found (the banner may not be shown to this scanner's location, the choice may sit behind a settings layer, or the control is not in the catalog). Results reflect the pre-consent state.

Recorded provenance is self-reported measurement metadata, not a cryptographic attestation. The public versioned report JSON contains the retained public evidence; see the methodology for interpretation and retention limits.

This report covers what the scanner measures, not everything a site can do. 17 browser surfaces are not instrumented at all (Every page except the one that was scanned; Anything that only loads after scrolling or interaction; Why a request happened, as a causal chain; and 14 others), 3 capabilities are declined by policy, and 3 are outside what any single visit can see. Their absence from this report is not evidence that they did not occur. Read the published coverage boundary.

Detector accuracy is unmeasured. No calibration study currently publishes a precision or recall for the detectors on this page, so a detector match here is a recorded observation, not a calibrated classification. How detector accuracy is measured.

Approved use boundary: This report is investigative evidence that requires independent corroboration. It is not a standalone legal determination and not the sole exhibit in a legal proceeding. Recorded in this project's release manifest on .
