Evidence quality

This report is built on an incomplete visit

Incomplete evidence: evidence was cut short before completion (the in-page fingerprint observer could not read every frame, so the fingerprinting evidence is incomplete). 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.

What this actually means

pbskids.org recorded 7 fewer third-party requests in the visit configured for Brave-list blocking.

The visit with no blocking made 122 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 4 requests; the remaining difference may include follow-on requests that never started once their sources were blocked, plus run-to-run variance.

Context

Bottom line: this visit has review-worthy signals

The scan observed signals a non-expert should not have to decode from raw request tables. Some detector evidence was incomplete; each affected detector card states its own retained or unavailable scope, while completed request, cookie, and storage measurements keep their recorded exactness.

The cards below translate the evidence into plain language; severity reflects fixed reference thresholds, not measured population percentiles. The request log, domain table, and methodology remain below for verification.

122 requests observed in one controlled visit.

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 7 request rows in this visit.Show matched requests

Nothing observed

Lower values observed across comparable metrics in the Brave-list blocking attempt

With the scanner 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; application was not verified), this paired visit showed 7 fewer third-party requests and 4 fewer tracking-related service requests.

Services only seen in the unblocked visit: Google. The blocking visit's engine directly blocked 4 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), so treat this as an observed difference, not a measured blocking rate.

Context

Privacy policy read; it made no statement this scan can check

None of the statements this scan knows how to check appear in the policy text, so nothing was compared against this visit's evidence (1 of 1 observed tracking company named in the policy). That is a limit of the automated check, not a finding about the site either way.

Statements checked automatically: blanket no-cookie claims, third-party-cookie claims, and combined do-not-sell-or-share claims against advertising-pixel identifier fields. Global Privacy Control claims are never checked against request counts, which cannot show whether selling or sharing stopped. Evidence collection was cut short, so this covers only what was recorded before the cutoff.

Policy at https://pbskids.org/privacy; 0 checkable statements matched; 1 of 1 observed tracking company named in the policy.

Context

Catalogued service domains recorded responses during this visit

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 analytics / tag management. This scan identified an operator for every one of the 3 third-party domains recorded here using catalog, consent-platform, reviewed-ownership, and CNAME evidence. The role taxonomy assigns these additional services explicitly non-tracking operational, support, security, consent-management, or hosting roles: Sentry.

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.

4 requests to these platforms.Show catalog-matched requests

Nothing observed

Google Analytics present, no remarketing signal

Google Analytics was observed, but no DoubleClick remarketing sync appeared in this visit.

Nothing observed

No third-party cookies observed

The automated visit did not observe third-party cookies.

This does not prove the site never uses cookies; it means this visit did not observe third-party cookies.

3 cookies total in this report.No third-party cookies observed.

Context

Incomplete evidence: No fingerprint-like API calls observed in retained evidence before collection stopped

The scan did not observe the instrumented high-entropy browser APIs.

This is an observation layer, not proof that fingerprinting is impossible. Evidence collection was cut short, so this covers only what was recorded before the cutoff.

Retained incomplete evidence includes 0 API event records; no exact API-family total is available.

Brave Shields Comparison

No blocking → Brave-list blocking delta

No blocking: 3,297msBrave-list blocking: 2,916ms

Some deltas are not comparable across these two visits and are not shown.

Other detector and causal-path deltas (each visit's own evidence still renders below): v1 never recorded detector versions, so fingerprinting and pixel deltas cannot be proven to come from matching instrumentation.
The Shields-number delta (each visit's own evidence still renders below): The two visits measured different Shields quantities (filter-list matches vs engine-blocked requests), which must never share a delta.
Fingerprinting deltas (each visit's own evidence still renders below): At least one visit did not complete the fingerprint measurement, so no exact cross-visit delta is shown.
Ad-pixel deltas (each visit's own evidence still renders below): At least one visit did not complete the pixel measurement, so no exact cross-visit delta is shown.

Measurement limits

7 conditions affect how this evidence reads

This report

Brave-list blocking comparison runs should be collected under matched crawl conditions, and the blocking run is a simulation with Brave's engine and default lists in this scanner's browser, not a live Brave visit. Differences can still reflect timing, experiments, cache state, consent state, or bot detection.
The two visits ran in randomized order; the "No blocking" visit ran first.

Both visits

Each visit in this report is one automated, headless Chromium visit from a fixed en-US / UTC profile, with no scrolling, clicking, or consent interaction. Sites can behave differently for real users, browsers, regions, accounts, or network locations.
Counts are a lower bound: trackers that load only after interaction or consent are not observed; Service Workers are blocked, and Web Worker or WebSocket traffic may be incomplete. 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, with storage keys read from the top frame only.
The in-page fingerprint observer could not read one or more frames, so fingerprint-like API calls and heuristics for this visit are incomplete.
Read the site's privacy policy (https://pbskids.org/privacy) 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.

Brave-list blocking visit only

Brave Shields block simulation was enabled; matching requests were aborted before loading and are not included in request totals.

How to use this report

Read the findings and measurement limits first, then inspect the evidence for each recorded visit. Comparisons include both visits, even where a difference cannot be interpreted.

Keep this PDF with its evidence package: the source JSON, correction context, export receipt and SHA256SUMS. The package preserves source bytes and the correction context at export time. Hashes check file consistency; they do not establish independent measurement accuracy or a signed attestation.

Retained observations from this visit. Missing measurements do not establish absence of activity.

Request attribution map

Which actor each third-party request is attributed to, from the initiator the browser reported. Attribution, not causation: an initiator may itself have been told what to fetch, and requests with no reported initiator are not distinguished from ones fetched from several. Asterisks mark subdomain labels hidden for privacy.

Attributed requests: 0
Not attributable: 7
Third-party requests: 7

No unique actor could be assigned to 7 of these requests. That includes requests for which the browser reported no usable initiator, and repeated URLs seen with conflicting initiators. This report does not distinguish those causes, so they are counted together rather than drawn.

7 third-party requests: 0 attributed to a single recorded actor, 7 not attributable.

No retained third-party request has one recorded actor to draw. This is not evidence that no actor was involved: the visit may have reported no actor or several actors for the same request.

Automated Chromium scan using Playwright 1.62.1 from github-actions-ubuntu with browser 151.0.7922.34, timezone UTC, locale en-US, the listed viewport, and Brave Shields classification only. Brave-list matching uses each route-evaluated request's initiating document (the parent document for a subframe navigation), under methodology shields-request-context-v2-adblock-rust-0.13.2-request-method-v1-playwright-1.62.1+subject-validity-v2+detector-coverage-v2; main-frame navigations are not blocked or counted as matches, and redirect follow-up URLs that Playwright does not re-route are not independently evaluated. Treat results as reproducible evidence for this scan configuration, not a universal claim about all visitors.

Automated Chromium scan using Playwright 1.62.1 from github-actions-ubuntu with browser 151.0.7922.34, timezone UTC, locale en-US, the listed viewport, and Brave Shields block simulation. Brave-list matching uses each route-evaluated request's initiating document (the parent document for a subframe navigation), under methodology shields-request-context-v2-adblock-rust-0.13.2-request-method-v1-playwright-1.62.1+subject-validity-v2+detector-coverage-v2; main-frame navigations are not blocked or counted as matches, and redirect follow-up URLs that Playwright does not re-route are not independently evaluated. Treat results as reproducible evidence for this scan configuration, not a universal claim about all visitors.

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. 16 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 13 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 2026-08-02.
