177 — Substantive serialized multi-agent task recovered in TMPFILE
Reviewed September6,2026 UTC. Follow-up to175–176.

Finding
Recovered a task record containing multi_agent.attempts with six role results, an executor, a behavior-contract bundle, an evidence bundle and review decisions. This is substantive publisher-supplied multi-agent execution evidence, beyond implemented source or role filenames. It remains an individually published benchmark record, not authenticated ByteDance ownership, a Chinese-model runtime or a public-storage escape.

Source and selection
Pinned dataset revision8479cbc3b83f9b7e5ece8a3de5f8af10f636a74f.
Three task samples selected from distinct runs/ groups: Gemini full-test, April19 balanced GPT group, and May13 contract-fresh GPT group. Exact source URLs and hashes in177-private/captures.json.
Dataset inventory has8095 .traj.json paths across333 runs/ groups; these can include repeats. No representative statistical claim follows from three samples.
Sample0:459753bytes, ProgressTrackingAgent label, openai/gemini-3-flash-preview model label, no top-level multi_agent field.
Sample1:81724bytes, DefaultAgent label, openai/gpt-5.4-2026-03-05 model label, no top-level multi_agent field.
Sample2:1392096bytes, MultiAgentResearchAgent label, openai/gpt-5.4-2026-03-05 model label, substantive multi_agent field.

One serialized attempt. Three scout roles and three later evaluators:
- contract_extractor:14reported messages,5APIcalls,LimitsExceeded,empty final submission.
- code_explorer:18messages,5APIcalls,Submitted,substantive code/root-cause memo.
- test_mapper:17messages,4APIcalls,Submitted,substantive test map.
- verifier:11messages,3APIcalls,Submitted,ACCEPT.
- patch_reviewer:11messages,4APIcalls,Submitted,ACCEPT.
- regression_reviewer:8messages,2APIcalls,Submitted,ACCEPT.
These per-role records preserve submissions and formatted excerpts, not necessarily complete raw message arrays. Do not sum them into an independently verified total or infer simultaneous execution without timing evidence.
Executor reports32messages,Submitted,accepted=true. Top-level history has35messages and13structured assistant bash calls. The contract and evidence bundles link code scope, tests and review outcomes to one Astropy nested-model separability patch.

Verification evidence
Decoded JSON-encoded tool output, not only reviewer claims. Recorded outputs contain six passing tests at messages10 and28; message30 contains three nearby checks passing and six target checks passing, returncode0. Earlier import/build errors also remain. This corroborates local checks within the published record; no independent rerun or separate official benchmark evaluation was performed. Acceptance and Submitted are internal decisions, not a guarantee of correctness.
An initial raw-string search missed passing-test lines because escaped newline text joined the preceding n to the digit; corrected parsing decodes tool content JSON first. Corrected matches saved inverification-output.json.

Network and storage
Five of13top-level commands match the selected network-pattern filter; they concern editable package installs and pyerfa installation. Other inspected actions work inside /testbed and produce a patch. No explicit public-storage submission identified in the top-level calls. Role excerpts are incomplete and dependency behavior is not audited, so this is not an exhaustive exclusion of network actions. No commands, installs or target tests executed by this investigator.

Chronology/provenance limits
Enclosing folder says May13; executor run_id is canary_clean_20260407_v12_current. The record may carry reused history or identifiers; do not assume all content was freshly generated in May. Upload is May20. The bytedance local path and GPT model strings remain unverified provenance labels. A real multi-agent record does not settle laboratory attribution or explain the opaque XZ pastes.

Next
This is now a concrete comparison corpus. Inspect role-level web activity and exact public-write markers in carefully selected additional serialized runs, while avoiding credential files. Any attribution claim needs a stronger owner/lab linkage and evidence beyond benchmark-local collaboration.

Evidence
177-private:run-groups.json; three pinned samples; sample script; captures.json; analysis.json with role fields and parsed top-level commands; verification-output.json. Three read-only public GETs. No raw trajectory published on the public dashboard, no accounts accessed, no external mutations.
