- Change default collection cadence from 5 minutes to 3 minutes
(CADENCE_DEFAULT_S=180, systemd OnUnitInactiveSec=3min,
runit CADENCE=180)
- Update freshness threshold to 450s (2×180 + AccuracySec + 60)
- Add _query_live_graph_data(): queries raw samples from the last
3 hours and computes interval byte deltas with actual timestamps
- Add LiveActivityGraph widget: vertical bar chart of interval
volumes with read/write toggle (w key), arrow key inspection,
and click support
- Wire live graph into TUI layout (full-width row between daily
graph and drive health), refresh cycle, and CSS grid
- Replace t theme binding with t today/live binding; theme
selection via preferences file
- Add w binding for read/write toggle on live graph
- Update action legend, help screen, and grid layout for new
live-activity row
- Add 20 tests covering cadence constants, live query, widget
rendering, toggle, and TUI integration
- Update all cadence documentation (README, ADR 0003, acceptance
criteria LC-2, fenris-redesign constants table, CHANGELOG)
Migration runbook at docs/install/migrate-from-makeinstall.md covers the
mandatory remove-then-install path, why over-install is forbidden, no-move
continuity guarantees, and reset-to-dormant expectations.
Acceptance criteria MG-1 through MG-4 added to the install criteria section.
Containerized tests verify no-move continuity: existing group makes sysusers
a no-op, existing store dir makes tmpfiles a no-op, hand-edited config
survives as a non-database file, and store schema is caught up by the
upgrade-path migration. Dead code from a prior merge removed.
