Its studio_server.py snapshot carries the owner's CodeQL autofix commits of 2026-10-18 (fa015d140, 077c2c81d; never imported or deployed; digest re-pinned the same day). Archived 2026-10-18 when v2.0.1 took the active slot: this snapshot's engine and cockpit still carry hardcoded model pins, including the retired claude-opus-4-7, as the build shipped them; it stays clickable for comparison and is labelled archived on the index. Served as a historical browser simulation with network connections denied; no server engine runs for this version. Artifact integrity does not validate the browser fallback as a replay of the archived Python engine.",
