Evidence quality

This report is built on an incomplete visit

Incomplete evidence: evidence was cut short before completion (the visit hit the scanner's request-recording cap, so its counts are truncated). Counts for the affected evidence are lower bounds; families that completed carry only their ordinary limits. The evidence receipt states the exact per-visit quality.

Public evidence correction

webmd.com: report corrected

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.

The underlying X pixel requests remain observations. Consult earlier clarification events for input-probe and policy limitations.

The original observations remain available below. Use them with the public correction; the original findings summary is withheld.

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. A study has been recorded for pixel-events and does not support a published rate under the current build. 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 .
