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.
Incomplete evidence: evidence was cut short before completion (request evidence was censored before completion — the producer recorded an additional collection loss (recorded loss count: 3)). 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
twitch.tv contacted 3 distinct catalogued tracking-related services during this visit.

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 the report's exact schema, methodology, tracker-catalog, ServiceRole-taxonomy, metric-contract, producer, and Global Privacy Control cohort, with each percentile card naming its metric-specific measured-site denominator (among 99 sites with a successful load across all cohorts; other methodologies, request-capped visits, and post-choice consent visits are excluded from this denominator, while failed or block-page attempts are outside that coverage), a curated set of popular, mostly commercial sites, not a random sample of the web, and otherwise uses fixed reference thresholds. The request log, domain table, and methodology remain below for verification.
280 requests observed in one controlled visit.
Worth checking
12 of 265 requests the engine evaluated matched Brave Shields filter lists
12 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 13 request rows in this visit.Show matched requests
Context
This GPC comparison supports no comparable delta
The pair did not record the network egress region for both visits, and an unrecorded condition never counts as matching. and The variant visit did not completely capture this evidence family, so its values are unavailable or incomplete rather than comparable totals.
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
Amazon Ads, Comscore and Nielsen 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 and audience measurement. This scan could not identify 8 of the 13 third-party hosts recorded here, so it cannot say who operates them. That is a limit of identity coverage, not evidence about the site.
84 cross-site requests across 13 third-party hosts.Below the median for third-party domains across the 54 sites measured for this metric. Modest distinct tracking-service entities count.Show third-party requests
Context
Requests were dispatched to major-platform domains the catalog does not carry
This visit dispatched requests to Google domains that the reviewed ownership map names, though the service catalog carries no entry for them.
Asset and font hosts reach this state often: the ownership map establishes who operates the domain, and nothing here establishes the request's purpose or payload. These domains are not counted as catalog-matched requests.
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.
11 cookies total in this report.At or above the median for third-party cookies across the 54 sites measured for this metric.
Context
Fingerprint-like browser APIs were called
4 high-entropy API calls 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 and webgl.getParameter.UNMASKED_VENDOR_WEBGL.
2 API families recorded.

cut short: request evidence was censored before completion — the producer recorded an additional collection loss (recorded loss count: 3); recorded by the scanner
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 .
