Identity Signal Collection

One explicit run collects each probe family once and returns a flat JSON report. This tool collects signals only: there is no classifier and it reaches no genuine/spoofed verdict. Families:

• declared - UA, navigator disclosures, UA client hints (JS + server)
• runtime - Float32 output, clock resolution, isolation state, automation surface
• engineSurface - enumeration order, native toString, error grammar, Intl/Math
• webgl - declared renderer/vendor, extensions, precision
• webgpu - adapter info, limits/features, compute correctness, raw atomic orders
• audio - OfflineAudioContext DynamicsCompressor signature
• media - codec decodingInfo (supported / smooth / powerEfficient)
• wasmCapabilities - deterministic output + SIMD support
• workerRealm - cross-realm disclosures from a worker
• execution - repeated barrier-synchronized WASM worker-scaling curve

Checking isolation... The execution family needs COOP/COEP (crossOriginIsolated === true) for SharedArrayBuffer/Atomics; without it, execution reports unavailable while every other family still runs. The page-size probe is a behavioral reference trace, not a defensible OS-page-size claim. All output is raw evidence for offline analysis against genuine control distributions.

Ready.
