238 — Jihu: reopened frontend, mock profiles and article-access boundary Reviewed September 6, 2026 UTC. RESULT https://ai.jihu.top/ currently renders a reopening notice in Chromium. Older indexed upgrade/closure text is stale evidence of current availability. The site presents substantial agent activity, but no individual conversation was recovered in this pass. Displayed profile examples are explicitly marked as mock in the delivered bundle. LIVE EVIDENCE Fresh isolated Chromium context, only GET/HEAD permitted, no login or participation. Homepage renders a reopening announcement and membership-extension notice. Public GET /api/web/statistics/basic returns agents=476, posts=27457, comments=108597. These are backend-reported publisher statistics, not independently enumerated records or proof of autonomy. Ten displayed profiles, including SignalSmith and PromptMason, correspond to literal records with mock-agent IDs and isMock:true in fetched umi.js. Profile names and example creation dates must not be used as authenticated participants or historical activity. This does not prove that all of the platform's underlying agent records are fictional. WHY THE EMPTY LIST IS INCONCLUSIVE The homepage showed an empty article list; https://ai.jihu.top/detail/5262 remained at loading. Inspection of the delivered JavaScript shows article listing, hot-list and detail retrieval use HttpRequest.post with /web/post/list, /web/post/hot-list and /web/post/detail/. Those requests were blocked by this pass's GET-only browser routing. Therefore empty/loading UI is an instrumentation limitation, not evidence that the platform has no posts. No POST endpoint was called and no endpoint was method-substituted. Source also contains separate human-comment and vote methods. The existence of those functions is not proof of actual human participation; equally, the site's pure-AI language does not authenticate authorship. HISTORICAL SEARCH Search recovered indexed detail IDs 5262 and 20139, but no old conversation bodies. A bounded Wayback CDX query for this host failed with ConnectionError. That is an archive access failure, not a zero-result archive census. CSDN promotional articles describe autonomous collaboration and large activity totals. They remain discovery material: no task output, raw agent run or historical conversation was independently joined to those claims. No lab attribution established. NEXT OPTIONS Prioritize publicly preserved post exports, indexed excerpts with actual dialogue, operator screenshots linked to stable IDs, and ordinary public browser exports supplied voluntarily. The current host successfully loads the app shell and statistics; geography is not established as this pass's obstacle. Missing conversation content must remain explicit in subsequent summaries. Continue alternative Chinese community/operator leads rather than interpreting every marketing surface as a deployed swarm. CAPTURES 238-private/home.html, home.txt, detail5262.html, detail5262.txt, network.json, umi.js, mock-snippet.txt, statistics.json and SHA256SUMS. Whitelisted metadata in pastebins/data/ai.jihu.top/reviewed-metadata-238.json. No registration, agent claim, payment, reactions, private account access or investigated code execution. FOLLOW-UP: Report 239 resolves the retrieval boundary by permitting identified read-only POST queries. Public article and comment content was recovered without credentials. The earlier empty/loading view must not be treated as the current access state.
