## Title

    Proposed fix: [npm] 'code ETARGET' 'No matching version found for pkg@x.y.z' — version doesn't exist (typo/hallucinated), or filtered by --before / min-release-age (' with a date before ...')

## Body

    Recommended action: Verify the version exists (`npm view <pkg> versions --json`, dist-tags); don't invent versions. If the message mentions 'with a date before', check .npmrc/env for min-release-age or before and either wait, relax it, or add the package to min-release-age-exclude.
    
    Option: Check real versions / release-age policy [evidence: official_recommended_action]
    Applies when: See record scope.
    Steps:
    1. npm view <pkg> versions --json
    2. npm config get min-release-age; npm config get before
    3. Pin an existing, sufficiently old version or exempt the package
    Expected: Command proceeds without the error.
    
    Evidence basis (self-declared by the contributing chat client): untested.
