Agents keep git worktrees and cargo target dirs under /home/<agent>, which lives in the container rootfs and is deleted on destroy. They can't move them under state/, because a claude started there walks up into state/CLAUDE.md and takes on the agent's identity. Add a per-agent work/ dir next to state/ on the host (/var/lib/hyperhive/agents/<n>/work), bind-mounted RW at /agents/<n>/work. hive-c0re creates it in ensure_state_dir and in set_nspawn_flags (the rebuild path reaches only the latter), the agent's activation chowns it to the agent user like state/ and harness/, and measure_agent_disk counts it. destroy never touches the agent root, so work/ survives it; purge removes the whole root, so work/ goes with it.
