083 — Live listing follow-up after the completed survey
Reviewed September 5, 2026, 20:16 UTC.

Finding
The current public Ubuntu listing exposes two numerical IDs beyond the final survey boundary4552953:4552954 and4552955. Both were fetched read-only and contain readable C++ code. Neither is a visible continuation of the xinzhai/xz record families. The largest ID linked by this fetched listing is4552955; this is not an assertion that no unlisted or later-created page exists.

New records
https://paste.ubuntu.org.cn/4552954 — cpp tag, displayed2026-09-05 18:45,502characters,33lines. Readable array/range-update style C++ code.
https://paste.ubuntu.org.cn/4552955 — cpp tag, displayed2026-09-05 20:02,2603characters,151lines. Readable C++ with bitsets, graph traversal and counting routines.
Both carry the same displayed author label as the previous final survey page. That is website metadata, not authenticated identity. Dates are literal site displays, not independently normalized UTC.
No authored-body occurrence of xinzhai,xz_knowledge,xz_improvement,knowledge_p1 orimprovement_plan_p1 was found. Both fail the broad opaque Base64-alphabet screen because they contain ordinary source-code punctuation. Code was read, never executed; there is no attribution claim based on its algorithm or style.

Provenance
Root listing captured2026-09-05T20:14:15.954693+00:00,HTTP200, SHA-2565729a6f41e8d6234b032a4f0f0ec7abcc20869de910cd8d9348a7b71329efa9c.
Two new pages captured20:14:43 and20:14:46 UTC,HTTP200. Raw and authored-body hashes are in083-private/new-post-metadata.json; root metadata and links in083-private/metadata.json. All three raw HTML responses are private. Three total public GETs, no writes or tests on the original service.

Counting and limits
The completed4,872-page survey and3,484-record xz analysis remain fixed historical inputs. These two follow-up pages are separate observations. The public /posts export remains the user-authorized1,142 records. No new raw payload was added to that export.
This check establishes that newly listed content has been reviewed through the observed boundary at this capture time. It does not detect changed old pages, unlisted records, renamed records on other sites, or future uploads. No continuous polling process is claimed to be running.
