  "limitations": [
    "This is one saved Foundplay catalog snapshot, not a census or representative sample of browser games or developers.",
    "Original is the existing listing classification; this extraction does not independently certify originality, rights, quality or general-audience suitability.",
    "Phone and multiplayer values are recorded listing metadata, not fresh physical-device or gameplay verification.",
    "Multiplayer includes playing with others online or on the same screen; it does not establish remote multiplayer, cross-play or device compatibility.",
    "Null means unknown. Unknown values remain in the denominator and are never treated as false.",
    "Every percentage uses the same selected-listing denominator and is rounded independently to two decimal places; rounded cells may not sum to exactly 100%.",
    "Counts describe supply recorded in this catalog, not player demand, market share, business opportunity, usage, retention or traffic.",
    "The backup last-modified timestamp records file finalization, not an independently verified exact database transaction cutoff. Extraction time is not live observation time.",
    "Listings may change or be removed after this saved snapshot. The row manifest is evidence of the saved snapshot, not a live availability guarantee.",
    "No user, contact, visit, click, play, raw description, external play URL or traffic data is included."
