Wire the Soul Signature research (docs/research/soul/) into BFLD as a
consent-based opt-in that runs at privacy_class = 1 (derived). BFLD becomes
the policy-enforcement and compliance layer for Soul Signature; the two
share the AETHER encoder, the witness chain, the RVF container, and
cross_room.rs.
ADR-118 §1.4 (new): comparison table of intents, consent models, ID spaces,
and shared assets. Explains why the two systems are complementary, not
antagonistic.
ADR-120 §2.7 (new): dual-ID-space contract.
- Default BFLD: class 2, daily-rotated rf_signature_hash for all.
- Soul Signature opt-in: class 1, rotating hash for unenrolled + stable
opaque person_id for enrolled. No collision.
- Class 3 (restricted): Soul Signature disabled.
Static enforcement via --features soul-signature feature gate.
ADR-121 §2.6 (new): Soul Signature Recalibrate exemption + enrollment-
quality gate.
- SoulMatchOracle suppresses Recalibrate when high score traces to an
enrolled person_id (matched outcome is intended, not an attack).
- identity_risk_score doubles as enrollment-quality signal: Soul Signature
enrollment requires score >= 0.65 sustained over the 60s window.
- Exemption is asymmetric: unknown high-separability clusters still
trigger Recalibrate.
ADR-122 §2.7 (new): three Soul Signature HA entities exposed at class 1
only, structurally rejected at the Matter boundary. Fourth blueprint
(enrolled-person arrival notification) ships under feature flag, default
off, per-person opt-in.
