  "limitations": [
    "The 1,012-record index is a curated convenience sample, not a representative sample of all startups.",
    "Region is reported only when explicitly present in the coded record; missing locations are not inferred.",
    "Revenue time-basis signals are reproducible regular-expression matches and can overlap or miss uncommon phrasing.",
    "Acquisition breadth uses eight normalized text-match families and does not measure spend, sequence, conversion, or effectiveness.",
    "Difficulty bottlenecks use editorial ordinal scores; ties are retained and category shares can sum above 100 percent.",
    "Source-host concentration measures structured link destinations, not source independence, accuracy, ownership, or claim quality.",
    "All downloadable files contain aggregate results only; no restricted row-level project export is published."
