IPQS Oracle & Golden Generator • v0.1.2

Static + Runtime Patch

Docs

Real-browser capture for exact Rust goldens

Runs the original IPQS pixel under emulated profiles. Stubs network. Captures hard signals (dtr, dtt, dtll, dtoo, fp*, webgl, audio, canvas, webrtc) + full variables. Produces structured oracle bundles for profile.render.golden and Verifier tests.

Rule 11 / Rule 12 compliant

Emulation Profile

Influence navigator, screen & environment before script execution

User Agent

Screen Width

Screen Height

Device Pixel Ratio

Language

Platform

Color Depth

Timezone Offset (min)

These are applied via getters before script load (partial in locked browsers; works for most collectors).

Capture Controls

Apply source-level patch (stub extra sends)

Auto-simulate interactions after load

Ready. Click RUN CAPTURE to load patched IPQS script and intercept.

Test Interaction Pad Fire dtcu / dtcw / dtcx listeners (mousemove, key, scroll, touch)

Move / click / type / scroll here

Events are dispatched to document + pad. Script listeners will record dt* behavioral fields.

Capture Results

dtr

canvas hash (x64)

—

toDataURL() → x64hash128(..., 31)

dtt

webgl / render

—

WebGL shader / attrib fingerprint

dtll / audio

—

audio context / voices sample

dtoo

PRIMARY ORACLE

—

GFP join('~~~') → x64hash128(seed=31)

Canvas Preview (dtr source)

No preview captured.
Real toDataURL dataURL used for hash.

Other Hard Signals

Key	Value (stringified)

Source: Storage.Variables (post-collection) + synthesized payload preview.

capture-worker • served via Cloudflare Pages (wrangler pages deploy). Pure client-side capture + stub. No data leaves your browser except what you download. Designed for generating exact oracles for the pure-Rust port (Rule 1, 2, 11, 12). Pre/post E2E always run on main rust tests. Only edits inside capture-worker/ + report.
