058 — REVIEWED: eight-task client and external-memory search wave
Reviewed September 5, 2026. Tasks CN26L001–CN26L008.

Result
No public client was joined to xz_knowledge_p1 or xz_improvement_plan_p1. This wave found ordinary paste clients, a misleading xinzhai namesake, additional discussion of the already-known macw destination, and a primary evaluation-report lead followed in report059. No independently attributed Chinese swarm is established.

Scope
Eight OpenRouter tasks completed under the persistent shared $20 incremental session guard. Each had six search, four fetch and one archive allowances and twelve model steps. Completion is not exhaustion of the research question: three tasks reached step limits, and tool argument-type errors occurred. Runner reports zero terminal harness errors, which must not be described as zero tool failures. Baidu returned challenge pages; GitHub code search required authentication; grep.app was blocked/cooling. These are access gaps. Public read-only methods only; no Ubuntu refetches or user writes.

Client sources independently reviewed by coordinator
1. https://raw.githubusercontent.com/djc-Sherlock/checkin/main/xinzhai.js
The source collects today's convertible-bond subscription names and sends a notification. The spelling xinzhai corresponds here to new bonds, not evidence of the Ubuntu uploader or the speculative name 心斋. No paste upload appears in this file. Static source inspection only.
2. https://r.lily-is.land/tusooa/apps/src/branch/servant/bin/paste.perl
A generic Perl CLI handles standard input or command output, optionally adds Base64 instructions, and submits through WWW::Mechanize to Ubuntu Paste. It uses the environment username. The displayed commit date is March24,2018, a source claim. The reviewed file does not contain the xz labels or a recurring multipart storage workflow. Its Base64 mode adds a readable instruction header, unlike the observed bare xz bodies. No source code was executed.
3. https://raw.githubusercontent.com/skorokithakis/pastebinit/master/pastebin.d/paste.ubuntu.org.cn.conf
This configuration maps poster, code2, class and a submit value for the Chinese Ubuntu paste service. It establishes generic client support, not the observed uploader's identity or activity. A form field mapping does not demonstrate a plus-handling bug. Correct form URL encoding preserves a literal plus through percent encoding; do not blame quote_plus/urlencode merely for their use.
These three cached source extracts were inspected and preserved in058-private with hashes. Independent web-tool retrieval of the first two failed; the original successful runner capture, not that failed retrieval, supports the review.

Other task triage
L001 andL004: exact-label searches mostly returned known paste pages. GitHub issues search returned no xz_knowledge_p1 result, while code search was inaccessible. Generic improvement-plan framework hits did not establish a label-to-writer join. No global absence claim follows.
L005: Hermes issues12456 and17998 link developer debug reports on paste.rs; the retrieved issue/docs extracts describe a diagnostic sharing flow. This is a useful alternative explanation for model-related paste traces, not verified persistent external agent memory. One checked paste returned404; expiry is a possible explanation, not proved by404. Further body review is unnecessary absent a stronger behavioral lead.
L006 andL007: additional ClawdChat pages advertise the same macw message wall. Repeated destination URLs do not establish independent operators. Parent post authors must not be confused with commenters, and claims of immutable storage or autonomous replies are unverified. No new external destination was verified. A dreamnet.ink mention remains an unreviewed lead, not a finding.
L008: secondary Kimi evaluation coverage led the coordinator to Frontier Security's primary report. See059 for the narrower verified interpretation and source limits.

Next actions
Follow the exact primary evaluation disclosure and seek public run traces or reproducible benchmark context. Prefer documented code joins or independent dated artifacts over repeating exact xz searches through the same unavailable services. The Ubuntu shape and cadence review remains055/056; post-series continuation screen057 found no match to that exact short space-damaged shape among575 later validated pages.
