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.
Scan report ready for www.python.org: 32 recorded request rows.
Comparison Reportv1 schema · facts legacy-derived · descriptive report
Context
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.
Context
2 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.
Nothing observed
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 1 fewer third-party request.
The blocking visit's engine directly blocked 2 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
None of the statements this scan knows how to check appear in the policy text, so nothing was compared against this visit's evidence (no catalogued tracking companies observed to check against it). 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.
Context
Google were named by consent-platform signatures, reviewed ownership, or CNAME evidence without being classified as tracking services.
Operator identity and tracking classification are separate: naming an operator does not prove that a request was for tracking. This scan could not identify 2 of the 3 third-party hosts recorded here, so it cannot say who operates them. That is a limit of identity coverage, not evidence about the site.
Context
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.
Nothing observed
This visit did not contact Google Analytics.
Neither Google Analytics nor its remarketing sync was observed in this visit.
Nothing 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.
Nothing observed
The scan did not observe the instrumented high-entropy browser APIs.
This is an observation layer, not proof that fingerprinting is impossible.

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.

Integrity and provenance
20260817-1690ee88f26d7759817e1a3c2f26c905Recorded 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 .
