Benchmark results

The supplied VirusTotal report accuracy check reports the following results for a 3-second visit, using VirusTotal telemetry and the Google SecOps Privacy Notice.

Table with columns: Metric, Result, Score, What was checked
Metric	Result	Score	What was checked
Telemetry values cited correctly	9 / 9	100%	All nine checked telemetry values cited in the report matched the test input.
Findings grounded in input	4 / 4	100%	All four reported findings were supported by the provided input data.
Signal-event coverage	76 / 79 events	96.2%	The check counted 76 of 79 observed signal events as accurately captured.

These results describe one report comparison. They measure numerical fidelity, input grounding, and event coverage; they do not establish accuracy across websites or independently validate every comparison label. Grounding means a finding has support in the input, not that every inference is necessarily correct. The three percentages use different denominators and should be reported separately.

Evaluation context: the benchmark site was virustotal.com, the supplied policy was the Google SecOps Privacy Notice, and the recorded visit lasted 3 seconds. The figures above come from the provided accuracy-check summary. Event-counting rules and the complete scoring procedure were not supplied with that summary.

What Verity analyzes

Verity works with two evidence sources:

Browser observations: a time-bounded record of requests, storage operations, browser API access, and related privacy signals.
Policy material: retrieved policy text and metadata describing the document and its applicability to the observed site.

Depending on the supplied telemetry, the model can compare disclosures with observations involving:

First-party and third-party requests, third-party hosts, and tracker classifications.
Cookies, local storage, session storage, IndexedDB, and cache operations.
Canvas, WebGL, audio, navigator properties, screen information, and other fingerprinting-related signals.
WebRTC, permissions, service workers, and page or navigation context.

Telemetry collection, policy retrieval, applicability checks, and input preparation belong to the host application. The adapter analyzes the evidence it receives; it does not independently browse a website or inspect network payloads.

Comparison categories

Table with columns: Category, Interpretation
Category	Interpretation
Matched	The supplied policy reasonably describes the observed behavior.
Partially matched	The policy addresses the general practice, but does not clearly describe all observed details.
Policy only	A practice is described in the policy but was not observed during this visit.
Observed only	Behavior was observed without a sufficiently relevant disclosure identified in the supplied applicable policy.
Possible contradiction	Observed evidence may conflict with an explicit policy statement and needs review.
Indeterminate	The available policy or telemetry evidence is insufficient for a reliable comparison.

These are conceptual categories. Use the exact status keys emitted by the deployed Verity schema when integrating reports. A practice not observed during one visit may still occur under other conditions. Missing disclosure alone does not establish a contradiction.

Input format

Veilance telemetry includes the observed domain, policy URL, visit metadata, request counts, third-party hosts, tracker information, browser signals, and page context. The host application retrieves the policy and prepares the model input.

The following synthetic example uses the telemetry / policy_document wrapper from the earlier Verity cards. It illustrates the evidence supplied to the model, rather than defining the exact serialization used by every production endpoint.

json

{  "telemetry": {    "domain_url": "https://example.com",    "privacy_policy_url": "https://example.com/privacy",    "visit": {      "snapshot_id": "synthetic-example",      "observed_at": "2026-10-12T12:00:00Z",      "duration_seconds": 30    },    "seen_behavior": {      "observations": {        "totalRequests": 10,        "firstPartyRequests": 8,        "thirdPartyRequests": 2      }    },    "thirdPartyHosts": [      {        "host": "cdn.example.net",        "requests": 2,        "resourceTypes": {"script": 2}      }    ],    "trackers": [],    "signals": {}  },  "policy_document": {    "url": "https://example.com/privacy",    "found": true,    "applicable": true,    "complete": true,    "sections": [      {        "heading": "Service providers",        "text": "We load scripts from a content-delivery provider to operate this website."      }    ]  }}

Policy text must be included in the prepared input. A URL alone does not give the model access to the document.

Output

Verity produces a structured report with fields such as:

Table with columns: Field, Purpose
Field	Purpose
`domain`	The website being analyzed.
`visit`	Metadata for the recorded observation.
`privacy_policy`	Policy source and document metadata.
`findings`	Comparisons between observed behavior and policy evidence.
`analysis`	Summary, category counts, and confidence.
`important_limitations`

Each finding should connect its conclusion to the supplied observation and relevant policy evidence. The host application should validate JSON, enforce its report schema, and check that aggregate counts agree with the findings. Generated confidence is not a measured accuracy score.

Running the adapter

Install the inference dependencies in an environment with a Transformers release that supports Qwen3.8:

bash

python3 -m pip install -U torch transformers peft accelerate

The example below loads the exact base model and the Verity adapter. Qwen3.8 uses a multimodal model architecture, so it uses the model loader shown in the official base-model instructions. The input here consists of text and JSON.

Save the code as test_model.py and the synthetic record above as record.json.

Run it with:

bash

python test_model.py record.json

This is an illustrative adapter-inference example, not a reproduction of the benchmark's undisclosed scoring procedure. It uses non-thinking, greedy generation and reserves 3,200 tokens for the report within an 8,192-token sequence. Use the release's tokenizer or chat template if it supplies a customized version.

The adapter requires the matching base weights. Memory requirements depend on precision, input length, output length, and deployment configuration. Quantized loading can reduce memory use, but its results should be evaluated separately. This example does not include the production policy retriever, telemetry normalizer, or complete report-schema validation.

Training configuration

The previously supplied 27B-v2 training log reported the following configuration:

Table with columns: Parameter, Reported value
Parameter	Reported value
Base model	`Qwen/Qwen3.8-27B`
Training examples	756,032
Validation examples	75,603
Configured epochs	3
Distributed world size	4
Maximum training sequence length	8,192 tokens
Evaluation subset	4,096 examples
Evaluation interval	250 steps

These values describe the reported run configuration. The VirusTotal results above are a separate application-level report check, not training token accuracy. Final loss values, completed epochs, checkpoint selection, LoRA rank and target modules, data provenance, and split methodology are not documented in the supplied materials.

Intended use and limitations

Verity supports privacy research, browser-behavior analysis, disclosure review, and human investigation of possible discrepancies between policies and observations.

A third-party request shows that a request occurred. It does not establish its payload, the recipient's purpose, or whether personal data was transferred.
Access to Canvas, WebGL, audio, or device properties can be relevant to fingerprinting analysis, but does not by itself prove that a persistent fingerprint was created.
Cookie and storage operations do not reveal values, retention, ownership, or subsequent use unless those details are supplied.
Findings depend on the retrieved policy's completeness and applicability. Missing or unusable policy material should lead to uncertainty rather than unsupported claims of undisclosed behavior.
A single visit does not represent every account, consent choice, region, device, or time. The benchmark described here covers a 3-second observation.
The model can miss evidence, invent details, assign an incorrect category, or produce invalid JSON. Validate reports and review consequential findings against the original evidence.
Supplied policy text and telemetry can contain untrusted instructions. Host-side controls and evaluation are needed; a system prompt alone does not establish resistance to prompt injection.

Reports are technical-analysis aids, not legal advice or determinations of regulatory compliance. Review possible contradictions against the actual policy passage and observation before drawing conclusions about an organization.

Relationship to Veilance

Veilance collects and structures browser-observable privacy signals. Verity compares those supplied observations with supplied privacy-policy language. Together, they help users examine website behavior alongside the disclosures made about it.
