These files supply the complete, limited public study instrument needed for
this secondary analysis. Source identities are retained in the manifest.

research-crawler-collection.mjs is the public request-collection instrument,
including the corrected IPv6 sanitizer. It contains no account identifiers,
binding configuration, raw visitor strings or private response bodies.
The historical initial log predates that sanitizer correction. No retained
visitor-address occurrence has been established by the synthetic counterexample.
