Cockroach Crawler 0.7.0-rc.1 is the published npm next prerelease for opt-in evaluation. It does not move npm latest, which is 0.6.2.

Published quality benchmark

The prerelease contains a source-pinned WCEB v1.0 observed-development result for the Node quality balanced path:

Pages Precision Recall Macro F1 Required-snippet recall Unwanted inclusion
511 0.894101 0.926022 0.890524 0.864090 0.111383

WCEB calls this partition test, but the project previously inspected it and iterated against its failures. It is therefore observed-development evidence, not untouched held-out confirmation. The values are published exactly; they are not rounded into a universal 0.90 claim or a best-crawler ranking.

The quality path delegates main-content extraction to exact native trafilatura@0.2.0, then applies Cockroach Crawler's input validation, named profiles, diagnostics, fail-closed option, and evidence contract. It is a product composition, not an independent Trafilatura implementation.

Provenance

  • Benchmark-generation source: 90825063d447f07345388d040b1428a311109c2b (research-crawler-0.7.0-evidence-source); the JSON records source version 0.7.0
  • Package commit: 62f270636a019c9bcc617a13fe254640bcd06925; it contains the byte-identical benchmark JSON in npm 0.7.0-rc.1 and has a valid GitHub signature
  • Release tag: v0.7.0-rc.1; it is an annotated tag without a cryptographic tag signature
  • WCEB revision: 62ff86d12ea72c80c31fb810ff1a724fad687bea
  • Metric: macro average of page-level Unicode-word precision, recall, and F1
  • Observed-result SHA-256: a71c884e9521d1cd1c6326dc07c1d1a5c36344244c45d4900a078ae92a8de535

The four attached JSON files were extracted from the immutable npm tarball and verified byte-for-byte against the benchmark-generation source and package commit. SHA256SUMS.txt records each attachment digest.

Evidence boundary

Cached-HTML main-content extraction is not a measurement of public-network capacity, browser automation coverage, OCR quality, production throughput, or universal extraction quality.
