walmart.com recorded 7 fewer third-party requests in the visit configured for Brave-list blocking.
The visit with no blocking made 420 requests; the visit configured to apply Brave's ad-block engine and default Shields filter lists (a simulation in this scanner's browser, not a live Brave-browser visit) recorded 7 fewer third-party requests. The blocker directly stopped 3 requests; the remaining difference may include follow-on requests that never started once their sources were blocked, plus run-to-run variance.
Bottom line: this visit has signals worth checking
The scan observed signals a non-expert should not have to decode from raw request tables.
The cards below translate the evidence into plain language. Where a measured distribution exists, severity ranks this visit against percentiles from this report's cohort, with each percentile card naming its metric-specific measured-site denominator; otherwise it uses fixed reference thresholds. That cohort is drawn from a curated set of popular, mostly commercial sites, not a random sample of the web. The request log, domain table, and methodology remain below for verification.

Setup
Both visits used headless Chromium in a desktop window of 1440 × 980, with en-US language and UTC time zone. Both ran from a GitHub Actions Ubuntu runner; the network region was not recorded. Neither sent the Global Privacy Control (GPC) signal.
Visits
Two visits configured to differ in Brave-list blocking: No blocking and Brave-list blocking.
Interactions
Typed a made-up test value into 1 form field in each visit, never submitting the form. No scrolling, clicking or consent interaction.
Outcome
Both visits completed.
What these visits could not see
Other pages on this site. Only the requested page's activity was recorded. The privacy policy was opened only to read its text, and none of its activity was recorded.
Signed-in visitors, other browsers and other regions. Both visits were automated, from a fixed en-US / UTC profile. Sites can behave differently for real users, browsers, regions, accounts, or network locations.
Anything that loads only after interaction or consent. Trackers that load that late are not observed, so counts are a lower bound.
Services the catalog does not name. Service labels use a US-biased hand-curated catalog, so regional services may be under-labeled.
Context
7 requests matched Brave Shields filter lists
7 requests matched the default filter lists of Brave Shields, the ad and tracker blocker built into the Brave browser, while loading normally.
Computed with Brave's own ad-block engine and default filter lists in classification mode: matched requests were not blocked by the scanner and remain in this report's observed request counts. Matching shows what Shields would target on this visit's traffic. An actual Shields visit blocks these and also prevents their follow-on requests, so this number is neither a measured block count nor the total effect.
The hand-curated service catalog separately matched 6 request rows in this visit.Show matched requests
Not flagged
Lower values observed across comparable metrics in the Brave-list blocking attempt
The blocking visit ran with the scanner configured to apply Brave's ad-block engine and default Shields filter lists. It was a simulation in this scanner's browser, not a live Brave-browser visit, and application was not verified. Compared with the unblocked visit, it showed 7 fewer third-party requests, 1 fewer third-party cookie and 2 fewer tracking-related service requests.
Services only seen in the unblocked visit: Criteo and Google. The blocking visit's engine directly blocked 3 requests; the remaining difference may include follow-on requests that never started once their sources were blocked. A single paired comparison can also reflect run-to-run variance (ad rotation, caching, experiments). Treat this as an observed difference, not a measured blocking rate.

Worth checking
1 first-party DNS alias matched tracking checks
Of the resolved targets, 1 matched Brave filter lists; those matches do not identify the operators.
The scanner followed DNS CNAME chains from first-party subdomains and checked resolved targets against the service catalog and Brave filter lists. These matches do not establish a request's purpose, profiling, or an intent to conceal tracking. A filter-list match alone is not a verified service identity or proof of tracking.
The page this scan read as the privacy policy held 1,827 characters of text, short enough to be the page before its policy loaded. As a result, no policy text was compared against this visit's evidence. That is a limit of the automated check, not a finding about the site either way.
The scanner that recorded this visit read a policy page a fixed second after it began loading. Some pages render their policy later, and some had requests refused by the scan's own traffic budget. A short read can therefore be the page around a policy that never arrived. Company mentions and policy statements recorded from it are not used; later scanner versions wait for the page to settle and withhold such a read.

Context
Catalogued service domains recorded responses during this visit
Criteo and Google appeared in the request log.
A catalog match identifies a maintainer-reviewed service/domain mapping; it does not establish why an individual request occurred, what it carried, or whether profiling happened. Functional catalog labels include advertising. This scan could not identify 2 of the 5 third-party hosts recorded here, so it cannot say who operates them. That is a limit of identity coverage, not evidence about the site. The role taxonomy assigns these additional services explicitly non-tracking operational, support, security, consent-management, or hosting roles: HUMAN Security.
403 cross-site requests across 5 third-party hosts.Below the median for third-party domains across the 81 sites measured for this metric. Modest distinct tracking-service entities count.Show third-party requests
Context
Requests were dispatched to catalogued major-platform domains
This visit dispatched requests to catalogued domains for Google.
The domain matches identify services, not the requests' purpose, payload, or whether any profile linking occurred.
The scanner observed cookie metadata whose domain crossed the scanned site's registrable-domain boundary. This report does not retain cookie values or partition keys, so it does not establish whether a cookie was a persistent identifier or could recognize a visitor across sites.
21 cookies total in this report.At or above the median for third-party cookies across the 81 sites measured for this metric.
Context
Input-monitoring signal involving a script from another domain
Listener coverage that could observe typing-related input events was registered through call chains that included a script served from another registrable domain. This scan did not establish the operator of that script.
This is a behavioral instrumentation signal from listener registration, stack-attributed script origins, and known-vendor requests: it shows the page was instrumented to observe interaction, not that anything was transmitted. Stack attribution records the script origins present in the bounded registration call chain. A cross-site origin in that chain does not by itself establish that the cross-site script registered the listener. That is because first-party code can register its own listeners through a helper served from elsewhere. A different registrable domain is also not by itself a different operator: sites commonly serve their own scripts from a separate asset domain. The card therefore says third party only when the catalog or reviewed ownership attributes an origin to another organization. On scanners that run the active keystroke-capture probe, actual transmission is tested separately (a synthetic value is typed, never real input, and no typed values are collected). Treat this card as a review prompt rather than proof.
Session-recording listener coverage: 112 interaction-listener registrations with https://*.walmartimages.com/ in the registration call chain. Input-monitoring listener coverage: 29 input-listener registrations with https://*.walmartimages.com/ in the registration call chain.

No fingerprint-like API calls observed
The scan did not observe the instrumented high-entropy browser APIs.
This is an observation layer, not proof that fingerprinting is impossible.

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.
Severity percentiles come from this report's exact schema, methodology, tracker-catalog, ServiceRole-taxonomy, metric-contract, producer, and Global Privacy Control cohort. Each percentile card's measured sites are among 99 sites with a successful load across all cohorts. Other methodologies, request-capped visits, and post-choice consent visits are excluded from each card's denominator, while failed or block-page attempts are outside that coverage.
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 .
