300M held about two days on kuhy's desktop: one Steam boot wrote 480k journal lines and the evidence for a curfew failure two weeks earlier was already gone when it was needed (2026-09-13). The three Arch copies of the journal tweak (arch_hardware, arch_perf_fixes, arch_perf_report) move to a 4G cap, and "large"/vacuum now mean past that cap — a 2G journal is deliberate retention, not a finding. Tests follow. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_015mLnUeoJ3mUwGRTowTUH6d

"title": "Arch journal cap 300M -> 4G, vacuum only past the cap",

"objective": "The systemd journal keeps weeks of history on kuhy's desktop, not days: a 300M cap held about two days once one Steam boot wrote 480k lines, and the evidence for a curfew failure was gone when it was needed. Every Arch copy of the journal tweak installs a 4G cap and treats 'large' as past that cap.",
