VEIL (Verifiable Emission-shaping for Identity-Leakage prevention) is the countermeasure counterpart to BFLD (ADR-118/121): where BFLD detects when beamforming feedback becomes identifying, VEIL shapes a node's own outgoing feedback so an unauthorized passive sniffer cannot re-identify people, while a legitimate receiver that shares the per-session key sees an unchanged link. Mechanism: identity leaks through the fine cross-subcarrier phase structure of a compressed beamforming report; throughput rides the dominant beam direction. These are (mostly) separable subspaces. VEIL composes extra keyed Givens rotations (the report's native primitive) over the fine subspace only. The rotation is orthogonal (energy-preserving -> not jamming), keyed per session (the AP inverts it -> throughput preserved), and fresh each session (a sniffer cannot average it back -> re-identification collapses to chance). Contents: - v2/crates/wifi-densepose-privshield: deterministic, dependency-free, WASM-ready pure-compute leaf implementing the attacker-vs-protector experiment, the four compliant controls, a throughput model, a machine-checkable "not jamming" compliance audit, and a pinned witness. 29 tests + doctest pass; clippy -D warnings clean; builds for wasm32-unknown-unknown. - docs/research/privacy-shield: 8-file research bundle (SOTA, threat model, design, compliance/regulatory, experiment protocol, market, roadmap). - docs/adr/ADR-288: formal decision record. Reference results (SYNTHETIC / L0, N=16 identities): passive re-ID accuracy 100% shield-off -> 7.8% shield-on (chance 6.25%); modeled throughput ratio 98.0%; emission energy ratio 1.000000 (compliant). All defense numbers are SYNTHETIC until a two-node hardware capture with a witness exists. Compliant waveform controls only; never jamming (47 U.S.C. 333/302a analysis in the bundle).
