Barry Walker
Barry Walker's work was selected for the XERJ Corpus Hub, the open reference memory AI coding agents search before they write code. When an agent meets the same problem, it gets this implementation back as a worked example, with the author and the repository attached.
Totals across every corpus @barryw appears in; a commit selected for two corpora counts once. Files and lines count the selected commits; each corpus indexes the whole repository at its pinned commit.

- Reuse a worked example: the commit “harden runtime palette delivery after review” (9 files · Python, C++).
- Answer from 1541ultimate's real Python source instead of memory (API design and specification).
- Where does 1541ultimate handle “harden runtime palette delivery after review”?
- What does tests do in 1541ultimate?
Search the GitHub repository GideonZ/1541ultimate with XERJ (https://hub.xerj.org/corpus/gideonz--1541ultimate). Run these in a shell, in order, and check each result before the next: 1. xerj --help (success: it prints usage). If xerj is missing: curl -fsSL https://xerj.org/get | sh 2. git clone https://github.com/GideonZ/1541ultimate 1541ultimate && git -C 1541ultimate checkout 7f47ac0af97d66616d422d73a6b319a113ab9c20 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./1541ultimate --url http://127.0.0.1:9200 --prefix 1541ultimate --progress plain 5. xerj autoindex map --url http://127.0.0.1:9200 Then answer my question from the indexed files and cite the ax_path of every hit.

The corpus is the whole repository at the pinned commit, not only the files of the selected commit.
Not installable yet: this corpus is not in the hub registry until its licence review passes, so xerj corpus add and xerj ask cannot fetch it. It becomes installable when this card says live in the hub.
Sign in with GitHub or Hugging Face to see more: every selected commit in full (commit date, every folder, licence review state, pin) and the pack builds of each corpus.
