- 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)

# fenris-collect runit run script — periodic NVMe collection scheduler.
|
|
#
|
|
# Runit service layout:
|
|
# /etc/sv/fenris-collect/run — this script (scheduler)
|
|
# /etc/sv/fenris-collect/log/run — logger to /var/log/fenris-collect/
|
|
# /var/service/fenris-collect — symlink to enable
|
|
# /etc/sv/fenris-collect/down — marker for dormant install
|

#
|
|
# Guarantees (must match systemd timer semantics):
|
|
# - Initial 2-minute boot delay (sleep 120 before first collect)
|
|
# - Completion-relative 3-minute cadence (sleep 180 after collect)
|
|
# - Bounded execution (timeout 90s on each collect)
|
|
# - No catch-up (fixed sleep interval, no Persistent=)
|
|
# - Serialized runs (runsv does not restart until exit)
|
|
# - Serialized on-demand (flock serializes fenris-collect execution)
|
|

# Spec: §8.4, §8.5, §8.6, ADR 0008
