176 — Workspace mirror: implemented multi-agent roles versus sampled single histories
Reviewed September6,2026 UTC. Follow-up to175.

Finding
The public TMPFILE mirror implements parallel research roles, but two additional sampled task files do not demonstrate those roles executing. Both record a ProgressTrackingAgent type, one message history and no serialized multi_agent/attempts structure. This is a substantive distinction: a directory called multi_agent_autoresearch_runs does not establish that each child task is itself a multi-agent run.

Pinned source
Dataset revision8479cbc3b83f9b7e5ece8a3de5f8af10f636a74f.
https://huggingface.co/datasets/Tuyuanpeng/TMPFILE/blob/8479cbc3b83f9b7e5ece8a3de5f8af10f636a74f/src/minisweagent/agents/multi_agent.py
856517-byte source defines MultiAgentResearchAgent. Inspected sections implement role-specific calls, environment/model clones, ThreadPoolExecutor and as_completed for scout roles, bounded by max_parallel_scouts. If parallel execution is disabled or resource cloning unavailable, it runs those roles sequentially. Post-role handling includes another parallel path. serialize adds multi_agent.attempts from attempt_records. This is implemented capability, not a verified live run.
The current swebench.py runner is also preserved. It uses configurable get_agent and does not define the historical ProgressTrackingAgent class string recorded in the samples. Current source cannot automatically reconstruct historical run settings.

Both config agent_type strings are minisweagent.run.benchmarks.swebench.ProgressTrackingAgent; both model_name strings are openai/gpt-5.4-2026-03-05. These are recorded labels, not independently authenticated model or runtime provenance. The date-bearing directory names precede the May20 upload, but are not independent execution timestamps.

Network-action check
Parsed assistant tool_calls.function.arguments rather than relying on textual mentions in retrieved source. All25 calls use bash. A narrow network-command filter selected five April calls: pip install pytest, pyerfa, extension-helpers and two editable local-package install attempts. These are package/build operations, not explicit public scratch-memory submissions. The March sample had no selected network-command matches. This does not exclude indirect network behavior inside tools, setup scripts or dependencies; source/package commands were not executed by this investigator. No demonstrated public-post write or partner-agent task handoff emerged from these two histories. Submitted means a patch was returned, not that evaluation passed.

Inventory cautions
There are8095 filenames ending .traj.json under runs/ and903 .traj.json-or-summary.json paths under multi_agent_autoresearch_runs/. These counts can include retries/duplicates and must not be reported as distinct agents. An initial filename search for planner.traj/researcher.traj/reviewer.traj/multi_agent.json found zero; source inspection explains that nested serialization, not separate role filenames, is another representation to seek.

Next
Sample candidates likely to contain multi_agent.attempts and inspect run metadata to locate the actual agent class used. The local bytedance path is still insufficient corporate attribution; nothing in this pass establishes a Chinese model or escaped fleet. This remains a useful public run corpus, with materially weaker multi-agent execution evidence than its folder names suggest.

Evidence and handling
176-private: two source captures with URL/hash metadata; two pinned trajectory JSONs with hashes; parsed call counts and selected network candidates inanalysis.json; sampling script and empty role-path lookup. Four public GETs. Only selected public source/run artifacts read; no credential/config files fetched, no downloaded code executed and no external mutation.
