### Added
- **Native P3 directory-build diagnostics (#780, #753).** Owner-local filesystem
snapshots distinguish dropped waiters, running or completed native directory
builds, retained transaction receipts, and cleanup phases. Eight records per
root bound storage; omitted observations remain explicit. Launcher trace logs
report guest-exit snapshots and the independent filesystem completion result.
- **Owner-local filesystem snapshots (#779, #756).** Host code can read bounded
root admission, retained-work counts, cleanup phases, and recorded-failure
presence through `FsCompletion`. Launcher debug logs sample this state after
presence through `FsCompletion`. Launcher trace logs sample this state after
guest exit. Reads report contention or unavailable state explicitly; guest
cancellation does not imply native work or cleanup has completed.
- **Wasmtime lifecycle metrics (#777, #753).** `/metrics` reports completed
