Lens is the curve-based threshold signing kernel for Lux. It is the classical analogue of Pulsar (the lattice kernel at github.com/luxfi/pulsar). Both kernels share the same lifecycle shape — Bootstrap → Reshare* → Reanchor — and the same activation circuit-breaker contract. They differ only in the math field: Pulsar over R_q (Module-LWE), Lens over a prime-order curve group (discrete log). Curves shipped: Ed25519, secp256k1, Ristretto255. Each has a deterministically-derived secondary Pedersen generator H from a Lens-specific nothing-up-my-sleeve tag. Sign math: FROST 2-round Schnorr threshold signing per RFC 9591 (Komlo-Goldberg 2020). Verifier checks z·G ?= R + c·X under the unchanged group public key. Reshare math: HJKY97 zero-poly Refresh + Desmedt-Jajodia ReshareToNewSet over the curve scalar field. Master secret s is preserved; only the share distribution rotates per epoch. Activation cert message format: QUASAR-LENS-ACTIVATE-v1, byte-equivalent shape to QUASAR-PULSAR-ACTIVATE-v1. Hash suite: HashSuite interface with Lens-SHA3 (production, cSHAKE256 / KMAC256 / TupleHash256) and Lens-BLAKE3 (legacy) profiles. DKG: distributed FROST DKG with Feldman commitments. No trusted dealer required at genesis if the chain prefers proper distributed DKG. KAT oracles: cmd/reshare_oracle and cmd/dkg_oracle emit deterministic JSON vectors for cross-language byte-equality validation against a future luxcpp/crypto/lens/ port. Tests: full unit + integration coverage on every shipped curve. 60 unique tests, 0 failures.
