Hong-Sik Yun
Hong-Sik Yun'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 @HongSik-Yun-Fusion 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.
What an agent can do with the vaft corpus
VEST-Tokamak/vaft: A standardized, verifiable, and interoperable scientific framework for machine-agnostic tokamak research, with full implementation on the…
- Look up how vaft implements database, fusion, tokamak, with answers cited to file and line.
- Reuse a worked example: the commit “Add lazy scientific animation galleries and responsive document drawers” (4 files · Python).
- Answer from vaft's real Python source instead of memory (Databases and storage engines).
- How does vaft implement database?
- What does vaft do in vaft?
Search the GitHub repository VEST-Tokamak/vaft with XERJ (https://hub.xerj.org/corpus/vest-tokamak--vaft). 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/VEST-Tokamak/vaft vaft && git -C vaft checkout fd858345f06bbd43106ad21a59db9bd47e266c54 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./vaft --url http://127.0.0.1:9200 --prefix vaft --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.
