131 — Public Ubuntu IRC log check, July 9–20, 2026
Reviewed 2026-09-05 UTC. No xz provenance link recovered.

Question
Could the paste bodies have been posted to support an IRC conversation, leaving a readable explanation or backlink in contemporary public logs?

Sources and method
Read the daily public text logs for #ubuntu-cn and #ubuntu at:
https://irclogs.ubuntu.com/2026/07/09/%23ubuntu-cn.txt
https://irclogs.ubuntu.com/2026/07/09/%23ubuntu.txt
The same paths were read for each calendar date July 9 through July 20 inclusive. The provided July 10 index links both channel text files:
https://irclogs.ubuntu.com/2026/07/10/
All 24 GETs returned HTTP 200. Requests were sequential with a 1.65-second pause after each. Captured bytes were searched case-insensitively for xinzhai, xz_knowledge, xz_improvement_plan, paste.ubuntu.org.cn and paste.ubuntu.com.cn. All capture SHA256 values were independently recomputed after the process completed.

Coverage and results
#ubuntu-cn: 12 daily files, 11 empty. The remaining file, July 18, has only a 35-byte nickname-change event. There are no timestamped conversation lines in the captured Chinese-channel records. This is effectively no conversational coverage, not evidence that the Chinese community was not discussing the subject elsewhere.

#ubuntu: 12 nonempty daily files totaling 76,305 bytes and 1,078 lines. Of these, 760 begin with the usual [HH:MM] timestamp; other lines include channel events. No checked marker appeared. These files provide a narrow negative result for these captured dates/channel only.

Interpretation
The direct-log route adds a check that web search might miss, but it yielded no paste URL, readable explanation, or xinzhai/xz mention. It does not rule out other networks, unlogged channels, private messages, logs outside this date range, different spellings, or a paste uploader who never used IRC. Even a paste URL in a log would demonstrate sharing, not necessarily authorship. No attribution can be made from this result.

No linked paste bodies were fetched, no messages posted, and no private channels accessed. The excluded paste was not fetched or opened.

Reproducibility
131-private/check_logs.py: bounded fetch and marker-check procedure.
131-private/logs-index.json: 24 URL/status/date/channel/file/size/line-count/hash entries plus marker results.
131-private/summary.json: independently checked totals.
