Public corrections ledger · SBL-CORR-2026-001
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.
Evidence quality
Incomplete evidence: evidence was cut short before completion (request evidence was censored before completion — the bounded public evidence projection did not finish (recorded loss count: 1)). 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.
Scan report ready for usa.gov: 40 recorded request rows.
Comparison Reportv2 schema (r2)request evidence incomplete
The selected visit did not finish collecting request evidence. Request counts are lower bounds; Run quality records the reason.
Worth checking
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.
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.
Worth checking
at least 13 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.
Context
The pair did not record the network egress region for both visits, and an unrecorded condition never counts as matching., The baseline visit did not completely capture this evidence family, so its values are unavailable or incomplete rather than comparable totals. 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
Google and Crazy Egg 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 session replay / behavior analytics. This scan could not identify 5 of the 8 third-party hosts recorded here, so it cannot say who operates them. That is a limit of identity coverage, not evidence about the site. Catalog labels include session-replay or behavior-analytics services: Crazy Egg; the domain match alone does not prove that a recording occurred.
Context
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.
Context
Google Analytics was observed, but no DoubleClick remarketing sync appeared in this visit.
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.
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.
Worth checking
The page registered broad interaction listeners through call chains that included a third-party script, and contacted a known session-replay service.
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.
Nothing observed
The scan did not observe the instrumented high-entropy browser APIs.
This is an observation layer, not proof that fingerprinting is impossible.
GPC Comparison
Both visits
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.
No unique actor could be assigned to ≥1 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.
≥16 retained third-party requests: ≥15 attributed to a single recorded actor, ≥1 not attributable. Request capture was incomplete, so every count is a lower bound and no coverage percentage is reported.

Recorded visit structure
Request counts are retained request rows whose start fell in each phase. A phase with no retained rows does not prove that no traffic occurred; some phase traffic can be intentionally excluded from the public request log.
| Phase | Span from run start | Recorded requests | Third-party | Catalog-matched requests | Cookie records | Storage records |
|---|---|---|---|---|---|---|
| Initial page loadP0 · passive-load | 0 to 2,719 ms (2,719 ms) | 40 | 16 | 8 | 5 present | 0 retained |
| Active input probeP1 · active-probe | 2,719 to 6,054 ms (3,335 ms) | No retained rows | No retained rows | No retained rows | 0 retained | 0 retained |
Changes are inferred from privacy-filtered snapshots at phase boundaries, not instrumented browser write events. Cookie values are never recorded; storage values are omitted and only byte counts remain.
4 change records hide unreviewed names or keys because they can contain identifiers.

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 .
