OpenPay (1 crate, 3277 LOC, 18 tests)
  op-ewallets-asia    APAC e-wallet rail adapters. Alipay Cross-Border v3,
                      WeChat Pay (JSAPI/Native/H5/MicroPay) with constant-time
                      HMAC notify, UPI 2.0 (collect/intent/mandate/VPA),
                      Paytm, GrabPay, GoPay (Midtrans), Touch'n Go.
                      EMVCo MPM TLV + CRC-16/CCITT-FALSE encoder for

                      Transport-free traits — operators inject HTTP + RSA-SHA256
                      signers (keeps POS firmware / WASM consumers reqwest-free).

Smart Byte (1 crate, 1310 LOC, 15 tests)
  smart-byte-zk       Selective-disclosure ZK primitives.
                      Real: Bulletproofs over Ristretto255 (range proofs at
                      8/16/32/64-bit), RangePredicate / InequalityPredicate /
                      SetMembershipPredicate all delegating to Bulletproofs.
                      Stubs (documented): Groth16, PLONK — deterministic
                      placeholder proofs satisfying ZkScheme trait for future
                      arkworks integration. AnonCred sketch + VerifiablePresentation
                      builder.

EOC (1 crate, ~3000 LOC, 36 tests)
  eoc-rag             RAG orchestrator. Naive (Lewis 2020), HyDE (Gao 2022),
                      RAG-Fusion + RRF (Cormack 2009), Self-RAG (Asai 2023)
                      with Retrieve/ISREL/ISSUP/ISUSE critique tokens,
                      Corrective RAG (Yan 2024) with retrieval evaluator
                      + external fallback, Adaptive RAG (Jeong 2024)
                      complexity router. Chunking: sentence-window, semantic,
                      recursive, late-chunking. Span-backed citations with
                      3-mode enforcement. SelfCheckGPT consistency guard.
