Progressive enhancement: a brand-new agent's state root under /var/lib/hyperhive/agents is created as a btrfs subvolume when the host filesystem is btrfs, otherwise it falls back to a plain directory. No existing agent is auto-migrated — the new path only fires when the root does not yet exist, so plain-dir agents are left untouched until an explicit opt-in upgrade. Two new privileged ops (subvolume create/delete are root-only): EnsureAgentSubvolume statfs-gates on btrfs, creates the subvolume, and chowns it to the hive-core user so the normal state/claude/harness mkdirs succeed inside it; DeleteAgentSubvolume btrfs-subvolume-deletes the root iff it is actually a subvolume. hive-c0re calls Ensure before the per-agent dirs are created (spawn/rebuild/InitConfig) and Delete on the purge path only — destroy keeps the subvolume for revival, matching plain-dir semantics. btrfs-progs added to the hive-priv unit PATH. Per-subvolume usage accounting + optional quota is a separate follow-up.
