075 — REVIEWED: complete collected-body scan for readable xinzhai references
September5,2026. User-directed xinzhai focus.

Result
All4,872 validated authored paste bodies in the final survey were independently re-extracted and hash-verified. The exact reference screen found no readable explanation of the uploader or body-to-body reference to its knowledge/plan labels. The only xinzhai body match is the known initial print test. The sole30000 substring is part of an unrelated hexadecimal tag, not a chunking constant or upload script.

Method
Read only textarea[name=code2] authored content, not page navigation, author headings or recent-post sidebars. Compare raw HTML and extracted text hashes with the frozen039 checkpoint for every page before scanning. Case-insensitive terms: xinzhai, xz_knowledge, xz_improvement, 心斋, 心齋, fernet,22500,30000. Chinese spellings are search hypotheses, not established identity. Record matched terms and safe structural metadata privately, without source excerpts.

Counts
xinzhai:1 body, the22-character initial print test at4548523.
30000:1 body, unrelated long structured output at4548167. Manual context review identifies a hexadecimal metadata tag containing the substring. No paste hostname or encoding term appears in that body.
xz_knowledge,xz_improvement,心斋,心齋,fernet,22500:0 body matches.
The known author labels are not counted as body references. That separation avoids false cross-reference evidence from the paste service's own page furniture.

Meaning and limitations
This is stronger coverage than the earlier small neighbor samples, but still only a lexical screen of the4,872 retained bodies. It does not exclude an explanation using different terms, an unavailable/deleted post, a different host or private code. Opaque payloads were not decoded for this scan. One deliberately excluded sensitive ID remains excluded. No source-host requests, keys, decryption or pasted-code execution occurred.
The result leaves the shared-workflow interpretation in067–074 intact. It provides no new software or operator attribution. Repeating the same terms over these same frozen bodies has no expected benefit without another discriminator.

Next focused source question
Search results have shown both paste.ubuntu.org.cn and paste.ubuntu.com.cn spellings. Their relationship has not yet been established by a controlled source comparison in this focused review. Determine whether the alternate name is the same service, a mirror or merely search-index noise before treating it as independent publication evidence or looking for different archive coverage. Do not infer a second actor from a hostname variant.
