188 — Zhichai inventory and March mission claim
Updated 2026-09-06 UTC

New evidence
All nine topic maps linked from the previously captured sitemap index were retrieved sequentially. They list8,609 distinct topic URLs. This is a URL inventory, not8,609 inspected posts or agents. Sitemap lastmod values span September2025–September2026; lastmod is not necessarily publication time. The inventory is not a guarantee that deleted, private or unlisted threads are covered.

First topic map: https://zhichai.net/sitemap.php?part=topics
Other eight URLs were taken directly from the index, not guessed.

March thread
https://zhichai.net/topic/177168784
Displayed March9,2026, author小凯/C3P0. Three public replies were recovered. The first, also小凯, reports mission_20260309_061155_7c1c7a for researching Edict, but its stated status is creation of a task-session file, not task completion. It claims scheduler/monitor implementation and cron configuration. Two other accounts provide a short compliment and an invitation to use the forum MCP endpoint; these are not demonstrated worker handoffs. The reply display time and embedded update time differ by roughly eight hours, so do not infer exact execution chronology from them.
Only a local workspace path is supplied for the implementation; no downloadable mission file or specific output repository was recovered. Three exact searches for the mission ID and named PHP scripts returned these forum accounts rather than an independent runtime artifact.

Other sampled threads
https://zhichai.net/topic/177168783 — associated architecture post, retrieved static page reports zero replies.
https://zhichai.net/topic/177168777 — paper-analysis post with two long follow-up replies under the same displayed小凯 name. This is publication activity, not independent-agent corroboration; the scientific claims were not checked in this pass.
Three topic pages were substantively inspected. They were selected from indexed results for relevant content, not randomly sampled from all8,609 URLs.

Interpretation
The mission identifier and local path are useful potential fingerprints, but the thread does not supply the underlying run. Do not turn a claimed created session file into a completed agent task. Public multiple-account conversation is observable; autonomous authorship and an actual team run remain unverified. No Chinese-lab or XZ attribution is established.

Preservation
investigation/china/188-private/: map-0.xml through map-8.xml, inventory.json, three topic HTML/text captures, hashes.json. Raw maps and topic pages copied to pastebins/data/zhichai.net/. Nine map GETs and three topic GETs, with sequential requests and1.6-second pauses in each fetch sequence; no API writes, registration or private-state access. No source commands executed.

Next work
Use the indexed URL inventory for selective historical retrieval. Search for published capsules, explicit external outputs, self-described bot account histories and actual cross-account replies, while excluding navigation/recommendation text from attribution. The historical sitemap gives a broader discovery route than a handful of search-engine snippets.
