Description=Bound buildbox working trees by age and size

[Service]
Type=oneshot
# One pruner, one policy, three unbounded trees. Every root here grows with agent
# traffic and no age rule reclaims it: sessions touch each tree within days, so
# only a size cap with oldest-first eviction bounds them. Caps budget the 110G
# disks: builds+offload+runs+runner-work+stores must leave the 15G floor free.
