066 — REVIEWED: AgentWorldBench metadata and nine-record sample
September5,2026. Public read-only dataset review, no embedded actions executed.

Conclusion
The sampled records do not provide a public scratch-memory or swarm artifact. They are useful for clarifying provenance: reference observations, model prediction instructions, and real public website changes are different kinds of evidence. Dataset publisher identity does not identify the agent that generated each underlying trajectory.

Read the complete5,663-byte README and streamed bounded prefixes of search_test.jsonl (196,608 bytes), web_test.jsonl (327,680), and mcp_test.jsonl (589,824). Exactly the first three complete records of each prefix were selected. These are nine records but only five distinct domain/trajectory pairs: search and MCP samples each contain three turns of one trajectory; web contains three trajectories. This is a deterministic convenience sample, not a random or full-dataset review. Extra complete lines in captured chunks were not included in the nine-record analysis.

The dataset card reports2,170 evaluation samples across seven domains and describes response fields as ground-truth observations from environment execution. Each evaluation row selects a turn within a trajectory and includes preceding history. The model being tested predicts an observation; its reference is not simply a generated prediction. Correct any reading of report065 that treats all dataset records as synthetic. Publisher-provided provenance remains a claim until independently checked.

Observed sample content
Search trajectory185229208260426, turns1–3: action prompts request Beijing subway information, extract a Wikipedia article, and perform follow-up searches. Reference observations contain search results or extracted material. They do not demonstrate wiki edits or a posted note.
Web trajectories229,222,468: records show shopping/customer, shopping/admin and forum interfaces on example.com subdomains, with benchmark worker routing in page-state text. These are evidence of benchmark environment records, not proof of requests to a real commercial store or public forum. Embedded page navigation and login actions were not replayed.
MCP trajectory145256090131919, turns1–3: directory listing, directory-tree inspection and local file reading under a benchmark backup path. No public paste write is shown.

Field-level provenance correction
The initial broad URL screen pooled all fields. That included URLs in system_str examples, such as amusement-park sources unrelated to the transit trajectory. The follow-up separates prompt, response, current_prompt and system_str in066-private/field-provenance.json. Do not count instruction examples as visited destinations or independent artifacts. Likewise, repeated history across rows is not repeated independent activity.

A narrow marker screen found no paste.ubuntu, xz_knowledge, pastebin, paste.rs, dpaste, scratchpad or handoff strings in the nine selected records. This is not proof of absence from the dataset or of every possible storage mechanism. None of the sampled fields supplies per-row model identity or an authenticated publication timestamp for a public scratchpad.

Reproducibility and preservation
Script:investigation/china/066-agentworld-sample.py
Private files:066-private/repo.json, README.md.capture, three JSONL prefix captures, manifest.json, sample-summary.json and field-provenance.json. Manifest records pinned URLs, status, capture time, captured-byte count and SHA256. Prefix captures are explicitly not complete files. Source text and any embedded examples remain private; no payload instructions, credentials or sample actions were executed or used. Dataset requests were sequential and paced.

Next decision
This small sample provides no reason to treat AgentWorldBench as a discovered swarm. A wider pass, if pursued, should track distinct trajectories and field provenance, then review actual external-write actions before following any URL. Benchmark fixtures and templates must be excluded from cross-host corroboration. Continue looking for independently dated public behavior alongside dataset work.
