- Replace reflink rootfs copy with device-mapper snapshots (shared read-only loop device per base template, per-sandbox sparse CoW file) - Add devicemapper package with create/restore/remove/flatten operations and refcounted LoopRegistry for base image loop devices - Fix pause ordering: destroy VM before removing dm-snapshot to avoid "device busy" error (FC must release the dm device first) - Add test UI at GET /test for sandbox lifecycle management (create, pause, resume, destroy, exec, snapshot create/list/delete) - Fix DirSize to report actual disk usage (stat.Blocks * 512) instead of apparent size, so sparse CoW files report correctly - Add timing logs to pause flow for performance diagnostics - Fix all lint errors across api, network, vm, uffd, and sandbox packages - Remove obsolete internal/filesystem package (replaced by devicemapper) - Update CLAUDE.md with device-mapper architecture documentation
