Evidence quality

This report is built on an incomplete visit

Incomplete evidence: evidence was cut short before completion (the visit hit the scanner's total response-byte budget, so it stopped loading further content). 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

nasa.gov's retained request log includes catalogued Google domains.

Retained request rows include 2 distinct catalogued tracking-service entities; 2 of the retained service matches recorded responses across at least 7 retained cross-site domains. A catalog match identifies the service domain, not why the request occurred or what it carried. It also looks like keyboard-input listeners were registered through a call chain that included a cross-site script.

Worth checking

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 activity evidence was also incomplete: request counts are retained lower bounds, cookie counts are an incomplete end-state snapshot and storage counts are an incomplete end-state snapshot.

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.

at least 99 retained requests observed in one controlled visit.

Worth checking

at least 10 retained requests matched Brave Shields filter lists

at least 10 retained 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 at least 8 retained request rows in this visit.Show matched requests

Context

This Shields comparison is not conclusive

The "No blocking" visit exhausted its aggregate response-byte budget, so its request evidence is incomplete. The "Brave-list blocking" visit exhausted its aggregate response-byte budget, so its request evidence is incomplete.

The raw request logs of both visits remain below for transparency, but the diff between them supports no claim about what the compared condition changed.

Context

Catalogued service domains recorded responses during this visit

Google and Parse.ly 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 and audience analytics. This scan could not identify 1 of the 7 third-party hosts recorded here, so it cannot say who operates it. That is a limit of identity coverage, not evidence about the site.

at least 11 retained cross-site requests across at least 7 retained third-party hosts.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.

at least 5 retained requests to these platforms.Show catalog-matched requests

Context

Incomplete evidence: Google Analytics present, no remarketing signal in retained evidence before collection stopped

Google Analytics was observed, but no DoubleClick remarketing sync appears in the retained evidence.

Standard analytics collection was observed, without the stats.g.doubleclick.net advertising sync. Evidence collection was cut short, so this covers only what was recorded before the cutoff.

Google Analytics host observed; no stats.g.doubleclick.net request.Show catalog-matched requests

Context

Incomplete evidence: No third-party cookies observed in retained evidence before collection stopped

No third-party cookies appear in the retained evidence.

This does not prove the site never uses cookies; it means this visit did not observe third-party cookies. Evidence collection was cut short, so this covers only what was recorded before the cutoff.

5 cookies total in this report.

Context

Input-monitoring signal involving a third-party script

Listener coverage that could observe typing-related input events was registered through call chains that included a third-party 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: 21 interaction-listener registrations with https://cdn.parsely.com/, https://*.digitalgov.gov/ and https://www.googletagmanager.com/ in the registration call chain. Input-monitoring listener coverage: 4 input-listener registrations with https://cdn.parsely.com/ and https://*.digitalgov.gov/ in the registration call chain.

Context

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

The retained evidence holds no calls to 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 and Brave-list blocking: two visits, no comparable metric delta

No blocking: 6,004msBrave-list blocking: 8,239msRan first: Brave-list blocking
These two visits do not support a side-by-side comparison, so no deltas are shown.
  • The "No blocking" visit exhausted its aggregate response-byte budget, so its request evidence is incomplete.
  • The "Brave-list blocking" visit exhausted its aggregate response-byte budget, so its request evidence is incomplete.

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

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 "Brave-list 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.
  • This scan typed a synthetic test value into 1 form field with native form submission blocked. Focus, input and blur handlers may run and send requests. The value is synthetic and is not stored. Observed requests during typing and the following wait are included in the request log. Teardown-only transmissions are not measured.
  • The scan stopped loading additional response bytes after reaching the 64 MiB aggregate response-byte budget.

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.

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 .

Reports record one automated visit per condition; visits may be incomplete. On restart-safe deployments, an interrupted visit may be retried; attempts are never merged. Results describe these visits, not everything a site can do.
