135 — Publication/deposit and scheduler vocabulary search
Checked 2026-09-05 UTC. No matching XZ writer recovered.

Motivation: report132 supplies a Chinese author's actual statement that Pastebin provides convenient publication and a timestamp for a priority claim. Test whether XZ might be a versioned sealed deposit, rather than assuming every knowledge-labeled post stores newly learned facts.

Web queries included 心斋+存证; paste.ubuntu.org.cn+时间戳; pastebin+加密+存证; AI+加密发布+代码; pastebin+priority+encrypted+paper; Fernet+timestamp+priority+publication; pastebin+优先权; pastebin+dead man+Fernet; pastebin+保险+加密; exact host+定时; Fernet+存证. Returned results did not establish a Xinzhai link. The last query surfaced a concrete Chinese RentBuddy creator thread claiming encrypted local evidence storage; a separate source check is assigned report136. Generic marketing, unrelated support logs and similarly named items were not elevated to evidence.

The sealed-publication hypothesis fits only broad features: version labels, large opaque releases and accessible public dates. It does not by itself explain two recurrent small streams or the later irregular plan series. An actual linked manifest, author statement or deposit reader would be needed. A heartbeat/dead-man-switch explanation is another testable idea but no matching implementation surfaced; the cadence alone is insufficient.

Scheduler search: web searches for improvement_plan+21600 and knowledge+Fernet+300+paste returned no matched writer. Chinese six-hour/five-minute searches returned unrelated examples. Sourcegraph requests for same-file improvement_plan with 21_?600 or Fernet returned HTTP403; these are access failures, not zero-hit searches. Both initially attempted /search/stream and the previously used /.api/search/stream route failed. No authenticated access or challenge bypass attempted. Exact queries and errors preserved in135-private.

Next steps are source-led: follow OFIRM's actual public manuscript mirrors and inspect RentBuddy's linked implementation if available. Do not treat a common timer duration, a Chinese name or a mention of Fernet as attribution.
