František Borisjuk
František Borisjuk'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 @HangerThem 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 tessera corpus
HangerThem/tessera: A simple, privacy-first loyalty and membership card manager. Scan your physical cards once, then pull them up at checkout - no account, no…
- Look up how tessera implements digital-wallet, local-first, loyalty-cards, with answers cited to file and line.
- Reuse a worked example: the commit “App loads ZXing and bwip-js on every start” (19 files · TypeScript).
- Answer from tessera's real TypeScript source instead of memory (Cryptography, TLS and secrets).
- Where does tessera handle “App loads ZXing and bwip-js on every start”?
- How does tessera implement digital-wallet?
- What does src/utils do in tessera?
Search the GitHub repository HangerThem/tessera with XERJ (https://hub.xerj.org/corpus/hangerthem--tessera). 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/HangerThem/tessera tessera && git -C tessera checkout 093a82a42fc20919f1518513dbd4a3ef25466945 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./tessera --url http://127.0.0.1:9200 --prefix tessera --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.
