    "The 406-record index is a curated convenience sample, not a representative sample of all startups.",
    "Source coverage counts structured source records only; links embedded in editorial prose are not counted.",
    "Timing, team descriptions, tiers, and difficulty scores are editorial classifications rather than measured causal variables.",
    "The solo signal uses a conservative text-prefix rule and should not be read as verified current headcount.",
    "Channel pairs come from a documented regular-expression taxonomy and can contain false positives or omit synonyms.",
    "All files contain aggregate results only; no restricted row-level project export is published."
