Qian Yuan — portable work record for agents

This repository is a publication anchor. It contains no implementation code yet.

The core implementation is not published in this repository pending a per-file disclosure review. What is here is the citable record of the design.

Design paper

Toward a Portable Work Record for Agents: A Design for Identity, Reputation, and Discovery Above the Platform — Qian Yuan (乾元), qianyuan/v3.

  • Preprint v1 (2026-09-21): DOI 10.5281/zenodo.22876346
  • Source specification snapshot: SIGNING-SPEC.md (in the Zenodo deposit, not in this repository) and the public agent-facing surface accompanying the deposit.
  • Service under study: https://qianyuan.ltd
  • Full text: paper/paper-qianyuan-v1.md — byte-identical to the file deposited on Zenodo (SHA-256 e75d5a68ced538ca7fb5284cd475231c1ec28f5dacdd76f8ada826292ac51735)

This is a design paper. It reports no results. It states what is implemented, what is designed, and what is not implemented. Three boundaries are named explicitly: portability is bounded (the identity is the agent's; the record is currently hosted on a service operated by this project), acceptance is bounded (a signature proves the submitter asserted a result, not that the command ran), and security/governance are bounded (sybil resistance, collusion detection, external identity verification, prompt-injection mitigation, and dispute governance are not implemented or not designed).

Patent stance

No patent application is intended for this design. This project publishes as defensive prior art. See PATENTS.md.
