108 — HISTORICAL LAUNCH: July archive search for xinzhai/xz labels and copies
September 5, 2026. Historical partial checkpoint. The job is now complete; see111-july-archive-copy-final.txt for the audited final result.

New time coverage
Common Crawl's current collection index identifies CC-MAIN-2026-30 as July, spanning2026-07-10T07:05:34 through2026-07-23T01:13:28. This overlaps the source-displayed xinzhai/xz lifecycle and could retain copies absent in August. Earlier completed copy scans092/106 covered August; this pass adds a distinct crawl, not a restart of those jobs.
Primary index: https://index.commoncrawl.org/collinfo.json
Archive timestamps and source-displayed post times are different evidence; the source timezone remains unresolved.

Manifest and preflight
The existing July manifest contains100,000unique paths, all under CC-MAIN-2026-30. SHA-256:d18ec3be777be78ed34986d383faf522ae264c81343e13358e918bcd9dbfb68d.
A sample July object was accessible through the existing AWS host. A one-file production-binary preflight completed1/1files,21,165text records,0failures and0matches, reading62.5MB. This verifies the signed public archive retrieval and scanner path, not absence from the full crawl.

Patterns and execution
The5,993case-sensitive terms combine092's posted-form prefixes,106's inner-encoding prefixes and four observed label fragments: xinzhai_v, xinzhai_p, xz_knowledge, xz_improvement_plan. Private term SHA-256:dae886e00aeebdfc3e8ebc06485e7b78f2b778469dfd66402e3c1bc80ad8f125. Prefixes are kept private and never submitted as search queries to external indexing services; archive objects are read and searched on the existing AWS host.
The previously isolated binary was hash-verified unchanged. Full scan started2026-09-05T21:45:23.497656+00:00, PID1206392, output /data/runs/china-codex-xz-july. It uses384workers and streams public Common Crawl S3 inputs without writing another corpus. Existing8.6TB data is preserved. The dashboard binds only127.0.0.1:8097. Unlike the cached August passes, this scan transfers archive input data over the network.

Confirmed partial checkpoint
At21:45:46UTC, process alive:1,871/100,000files,43,503,867text records,0failures,0candidates,137,329,962,512input bytes counted. In-flight input transfers contribute to the download counter before their files finish. These partial counters do not establish absence.
Bounded observer polls every30seconds for up to40observations and never starts/restarts a scan:

The timestamp matters. An expired observer or request timeout is not proof that the archive process stopped.

Next action and limits
Continue this same job. Any label or prefix candidate requires source-body review; a label hit alone can be a namesake or quotation. After terminal completion, verify manifest coverage, failures and saved scores/matches before reporting a final result. Corpus records across different crawls may repeat pages; counts must not be summed as unique websites or documents.
Private108 contains term provenance, preflight.json and job.json; full output stays private. No original Ubuntu requests, corpus deletion, decryption, key search, new infrastructure purchase or OpenRouter wave occurred.173terminal bot reports remain unchanged. Existing AWS hosting costs are separate from the OpenRouter guard.
