Docs (engineering record, 502 LOC):
- DESIGN.md, LLM.md, README.md
- docs/ARCHITECTURE.md, docs/F_CHAIN_INTEGRATION.md, docs/M_CHAIN_INTEGRATION.md
Source scaffolding (1289 LOC):
- cert/ — QuasarCertLane registration + subject binding (M/F shared)
- types/ — ceremony, participant, proof, share substrate types
- protocol/ — package surfaces for cggmp21, frost, corona_general, tfhe_keygen
- runtime/ — F-chain and M-chain adapters
All Go files carry the Lux license header. Nothing here is generated or
fixture data; this is the signed-off design surface for the ThresholdVM
library used by M-chain and F-chain.
