+
+## 2026-04-03 — Phase 14.2: validated an explicit native FreeBSD runtime slice
+
+Completed work:
+
+- wrote the Phase 14.2 report:
+  - `docs/reports/phase14-native-runtime-freebsd.md`
+- added a new native package in `modules/fruix/packages/freebsd.scm`:
+  - `freebsd-native-runtime`
+- this runtime slice is built from `/usr/src` through the native world path and now prunes at least:
+  - `boot`
+  - `usr/include`
+  - `usr/share/doc`
+  - `usr/share/examples`
+  - `usr/share/info`
+  - `usr/share/man`
+  - `usr/share/mk`
+  - `usr/tests`
+- added a dedicated Phase 14.2 operating-system template:
+  - `tests/system/phase14-native-runtime-pid1-operating-system.scm.in`
+- added dedicated validation wrappers:
+  - `tests/system/run-phase14-native-runtime-qemu.sh`
+  - `tests/system/run-phase14-native-runtime-xcpng.sh`
+- the validated Phase 14.2 model now uses:
+  - `#:kernel freebsd-native-kernel`
+  - `#:bootloader freebsd-native-world`
+  - `#:base-packages (list freebsd-native-runtime)`
+- this makes the system composition more explicit:
+  - native world provides boot assets
+  - native runtime provides the guest runtime slice
+  - host base stores remain absent from the validated path
+
+Important finding:
+
+- this Phase 14.2 layout still duplicates some content because boot assets still come from the broader native world output while runtime comes from the separate native runtime slice
+- that made the earlier Phase 13 image sizes too small
+- the working values are now:
+  - local QEMU:
+    - `DISK_CAPACITY=12g`
+    - `ROOT_SIZE=10g`
+  - real XCP-ng:
+    - `ROOT_SIZE=10g`
+    - disk capacity still matched to the fixed 30 GiB VDI
+- the new Phase 14.2 wrappers now use those larger defaults
+
+Validation:
+
+- local QEMU/UEFI/TCG runtime wrapper passes:
+  - `tests/system/run-phase14-native-runtime-qemu.sh`
+  - workdir: `/tmp/phase14-2-qemu2-1775189802`

+    - `compat_prefix_shims=absent`
+    - `guile_module_smoke=ok`
+    - `native_runtime_ready=ok`
+- the wrappers also assert the runtime-split boundary directly:
+  - runtime store contains required boot-to-ready files such as:
+    - `/bin/sh`
+    - `/sbin/init`
+    - `/etc/rc`
+    - `/usr/sbin/sshd`
+    - `/sbin/dhclient`
+    - `/usr/bin/ssh-keygen`
+    - `/usr/share/locale/C.UTF-8/LC_CTYPE`
+  - runtime store no longer contains:
+    - `/boot`
+    - `/usr/include`
+
+Current assessment:
+
+- Phase 14.2 is complete
+- the validated Fruix guest now reaches ready state using an explicit native runtime artifact rather than reusing the broad native world output for both boot and runtime roles
+- the validated path remains host-base-free:
+  - native kernel

+  - native runtime as the guest runtime artifact
+
+Next recommended step:

+# Phase 14.2: validated an explicit native FreeBSD runtime slice
+
+Date: 2026-04-03
+
+## Goal
+
+Phase 14.1 proved that Fruix could boot without host-copied `/boot` material by sourcing boot assets from the existing native world output.
+
+Phase 14.2 removed the remaining model ambiguity on the runtime side:
+
+- the guest should now boot and reach ready state using an explicit native runtime output
+- not by reusing the broader native world artifact for both boot and runtime roles
+
+## Changes
+
+Added a new native package:
+
+- `freebsd-native-runtime`
+
+This package is built from `/usr/src` via the existing native world build path and prunes at least:
+
+- `boot`
+- `usr/include`
+- `usr/share/doc`
+- `usr/share/examples`
+- `usr/share/info`
+- `usr/share/man`
+- `usr/share/mk`
+- `usr/tests`
+
+The validated Phase 14.2 operating-system template now uses:
+
+- `#:kernel freebsd-native-kernel`
+- `#:bootloader freebsd-native-world`
+- `#:base-packages (list freebsd-native-runtime)`
+
+That means the model is now explicit:
+
+- native world provides boot assets
+- native runtime provides the guest runtime slice
+- host base stores are no longer part of the validated path
+
+## Practical sizing finding
+
+This Phase 14.2 layout still duplicates some native world/runtime content in the closure because the boot assets still come from the broader native world output.
+
+As a result, the Phase 13 image sizes were no longer large enough.
+
+Working values were:
+
+- local QEMU:
+  - `DISK_CAPACITY=12g`
+  - `ROOT_SIZE=10g`
+- real XCP-ng:
+  - `ROOT_SIZE=10g`
+  - disk capacity still matched to the fixed 30 GiB VDI
+
+The wrappers were updated to use those larger defaults.
+
+This is acceptable for Phase 14.2 because the next subphase is specifically about cleaning up the runtime/development/boot boundary further.
+
+## New files
+
+Added:
+
+- `tests/system/phase14-native-runtime-pid1-operating-system.scm.in`
+- `tests/system/run-phase14-native-runtime-qemu.sh`
+- `tests/system/run-phase14-native-runtime-xcpng.sh`
+
+These wrappers assert:
+
+- `host_base_store_count=0`
+- native kernel present
+- native world present as the current boot-source artifact
+- native runtime present
+- runtime store still contains the files needed for boot-to-ready
+- runtime store no longer contains `/boot`
+- runtime store no longer contains `/usr/include`

+native_runtime_ready=ok
+```
+
+## Result
+
+Phase 14.2 is complete.
+
+The validated Fruix guest now reaches ready state using an explicit native runtime artifact:
+
+- native kernel
+- native world for boot assets
+- native runtime for the guest runtime slice
+- no host-staged FreeBSD base stores in the validated path
+
+## Next step
+
+Phase 14.3 should clean up the remaining redundancy by defining clearer runtime vs. development boundaries and, ideally, replacing the temporary use of the broad native world artifact as the boot-source package with a narrower native boot asset package.
