Conclusion status

A human reviewer approved this relationship for the exact current evidence at 2026-09-16T14:18:48.469Z (UTC). The evidence below is the basis of that decision.

Evidence suggests babel/babel may succeed babel/babel-eslint (directional claim found). Human review required before publication. Supporting: a registry marks the predecessor package deprecated.

Seed context: Research question: is @babel/eslint-parser the successor of babel-eslint? The npm notice names the replacement directly.

Evidence (3)

Verbatim excerpts from official sources, whitespace-normalized. Full payloads are hashed and retained by the pipeline; collection failures never fabricate evidence.
