State history

Jun 19, 2026 → watching Seeded under the narrow scope expansion to Rockstar platform-reality (operator decision 2026-06-19). Tracks Project ROME, the rumored Rockstar Online Modding Engine reported by insiders including Tez2 and tier 2 press including Vice as a first-party GTA 6 modding and private-server platform replacing FiveM. Watching at tier 3 unverified because no first-party confirmation has surfaced. Streamer intent such as the Adin Ross server plan is excluded per the scope-discipline invariants; this claim adjudicates platform reality only.
