XINZHAI — DIRECT PUBLIC GITHUB REPOSITORY DISCOVERY
Reviewed2026-09-05. Three repository-name results; no link to the opaque paste client established.

Unlike the earlier general-web searches, GitHub's unauthenticated public repository-search API returned a successful200 response for xinzhai, total_count3 and incomplete_results=false. This is a concrete reminder that one engine's empty exact searches do not establish global absence. This endpoint searches repository metadata, not every code blob, private repository or deleted history.

Returned repositories:
https://github.com/m470988589m/xinzhai — metadata describes learning/happy; created and last pushed2015-12-22; size0, no language. No tree request made for this empty-labelled repository.
https://github.com/44678020qq-ctrl/xinzhai — description calls it a bazi/personality matching social system; created2026-05-19, pushed2026-06-05. Current tree has162 paths,10Python files named for astrology/rules/database functions, and a Next.js application. README is the ordinary create-next-app starter text.
https://github.com/lookinginmyeyes/xinzhai — created2026-03-14, pushed2026-03-28;44tree paths,noPythonfiles. package.json names healing-companion and lists Next/React/Supabase dependencies.

The two nonempty current trees were retrieved successfully without truncation. README/package evidence contains none of paste.ubuntu.org.cn, Fernet or xz_knowledge. This is a small context check, not an exhaustive code-content or history scan. A tree lacking an obvious client filename cannot rule out hidden functionality or unrelated versions. None of the inspected material ties a repository to the July paste labels,30,000-character multipart format, version sequence or periodic outputs. Similar romanized names do not authenticate identity or justify linking individual owners to the paste activity.

Five read-only public GETs total: one search, two trees, two raw text files. No repository cloned/imported/executed, accounts contacted, private files accessed, secrets inspected or source commands followed. Current main branches and repository metadata are mutable; hashes and retrieved tree SHAs preserve this observation, not a historical July software configuration.

Private captures, UTC/status/hash metadata, complete search response and tree files:046-repo-discovery/. Query: https://api.github.com/search/repositories?q=xinzhai&per_page=30 . The API result lists commit/push metadata as described above; it does not prove when paste content was posted.

Additional public code-discovery checks,12:13UTC:
One unauthenticated grep.app API query for the exact Ubuntu domain returned HTTP429. It was not retried or routed around the challenge; this is unavailable coverage, not absence of matching code.
GitHub repository search for the quoted domain with in:readme returned200, total_count2, incomplete_results=false: fluter01/paste (a Go paste utility already considered in034) and lovecn/WebDev-Source (an older web-development resource collection). These are repository/README search results, not a global code-content census. No new specific xz/Fernet multipart client was identified. No further source files were fetched for these already explained or weak metadata leads. Private raw responses and status/hash metadata are in046-repo-discovery/.
