Gap rule — more than 30 minutes since that visitor's last hit.\n// 2. Campaign rule — this hit's (utm_source, utm_medium, utm_campaign)\n// differs from what the CURRENT SESSION started with (not just the\n// previous hit — a session's attribution is pinned at its first hit,\n// and any drift from that pinned value ends it). This is what\n// actually fixes item 12: a visitor whose UTM params change mid-visit\n// no longer produces one session with contradictory attribution: the\n// change itself closes the session and opens a new, correctly\n// attributed one.\n// 3. Different visitor_id — trivial, since hits are grouped per visitor\n// before splitting.\n//\n// Midnight boundary rule: a session is NOT split at midnight. It is\n// attributed, for day-bucketed reporting, to the Eastern calendar day of\n// its FIRST hit — even if later hits in the same session land after\n// midnight.
