SBL-CORR-2026-001: The historical input-probe disclosure overstates coverage. Unload-only transmissions were not reliably recorded. Focus and blur handlers could run, and per-field failures were not fully counted. These reports cannot establish absence of input transmission outside their retained observations.

Plain-Language Findings

What this visit means

Unfamiliar terms are defined in the glossary
playwright-chromium

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.

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.

159 requests observed in one controlled visit.

Context

4 requests matched Brave Shields filter lists

4 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 3 request rows in this visit.Show matched requests

Context

Mixed changes observed 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 6 more third-party requests and 3 fewer tracking-related service requests.

The blocking visit's engine directly blocked 4 requests; ad rotation, experiments, or caching between the two visits can offset or outweigh what blocking removed, which is how totals can hold steady or rise despite direct blocks. 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

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 advertising. This scan identified an operator for every one of the 8 third-party domains recorded here using catalog, consent-platform, reviewed-ownership, and CNAME evidence. 2 catalogued cross-site domains belong to the same reviewed Google domain family as the site, so that traffic is not evidence of disclosure to an outside company.

Context

Major-platform domains matched within the site's reviewed organization

Google domains appeared across a registrable-domain boundary, but the reviewed ownership map groups them with the site rather than an outside company.

Cross-registrable-domain traffic remains counted in the report, but this reviewed ownership relationship does not support an outside-recipient disclosure claim. Naming the operator also does not prove request purpose.

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, whose operator this scan did not establish.

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, 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, so the card 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.

18 interaction-listener registrations with https://www.google.com/ in the registration call chain and 6 input-listener registrations with https://www.google.com/ in the registration call chain

Context

Fingerprint-like browser APIs were called

1 high-entropy API call appeared in the instrumentation log.

These calls can be legitimate (charts, graphics, media), so the count is observational, not a severity score, and it excludes Web and Service Workers. Top calls: webgl.getParameter.UNMASKED_RENDERER_WEBGL.

Brave Shields Comparison

No blocking → Brave-list blocking delta

No blocking: 6,850msBrave-list blocking: 6,806ms
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

6 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.
  • This scan typed a synthetic test value into 1 form field (never submitting the form) to test whether typed input is captured and sent to third parties. The value is synthetic and is not stored. Requests the page sent during and after this typing, including any unload beacons, are part of the recorded request log and counts.

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.

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
105
Third-party requests
105

No unique actor could be assigned to 105 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.

105 third-party requests: 0 attributed to a single recorded actor, 105 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.

Brave-list blocking — evidence

2026-08-07T04:10:43.951Z · complete; derived from status and warnings

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
111
Third-party requests
111

No unique actor could be assigned to 111 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.

111 third-party requests: 0 attributed to a single recorded actor, 111 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.

Provenance
Exact build and instrument digests were not recorded by this legacy schema.

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 .

Reports record one automated visit per condition; visits may be incomplete. Results describe these visits, not everything a site can do.
