Name no node in the last residuals: asus-zephyrus-g14's denylist, lab's and mosquitto's comments, mesh-issues's help texts, mesh-knowledge's decision fixture and ssh-client's forge-URL fixture (issue 1838)

novox/hq is the name of the software's own record, whatever follows it; asus-g14 is the laptop's name in
its vendor trigger file, declared in particulars as hardware asus-g14 (1838/AC2).

+# buildah
+
+The rootless image builder as a module (novox/hq ADR 0487, issue 1702).
+
+- **The only module that declares the package `buildah`** (`checks/toolchains`), and the only one that provides
+  `rootless-image-build` (`checks/imagebuild`; docker never does).
+- **Provides `rootless-image-build` with the machine's reach**: mesh-build-image requires it, so it composes only on a
+  machine where this module is assigned, and a node without it is refused at resolution naming `buildah`.
+- **No account and no subordinate-id word.** The node-engine makes every `user` account with `useradd`, which
+  allocates the account 65536 subordinate uids and gids; mesh-build-image's own account gets its ranges that way and
+  its health proves them (it reads /etc/subuid and /etc/subgid).
+- The helpers (an OCI runtime, passt, containers-common) come as buildah's package dependencies.
+- Holds no long-running resource, so it adds nothing to `health-undeclared`.

+| | a kernel-copying hook | a hook in `/etc/pacman.d/hooks` that the mesh did not write, triggered by kernel images and copying to one fixed file name in `/boot`, would put the fallback kernel in the default kernel's place: it is moved into `${dir:state}/taken-over/` and named in the unit's journal. Each kernel is then placed under its own package's name by the distribution's hooks |
+| file | `/etc/systemd/system/mesh-kernel-boot-entries.service` | oneshot, sandboxed: the file system read-only but for `/boot`, `/etc/pacman.d/hooks` and the module's state; no home, no network |
+| file | `/etc/pacman.d/hooks/90-mesh-kernel-boot-entries.hook` | runs the script after a kernel image is installed, upgraded or removed |
+| packages | `linux-lts`, `linux-lts-headers` | declared after the service and the hook |
+
 ## Tools
 
 | tool | | answers |
 |---|---|---|
+| `kernel_boot` | r | the loader (`systemd-boot`, `grub` or `none`), the menu's entries, the kernels in `/boot`, the entry booted (systemd-boot) or the kernel image booted (GRUB), whether the fallback kernel is on the menu with its kernel in `/boot`, and the room free on `/boot` in KiB |
 | `kernel_huge_pages` | r | the mode, defrag and shared-memory mode; each per-size control and what `inherit` resolves to; huge pages by kind from `/proc/meminfo` (MiB); the units holding the most file pages in huge folios (`memory.stat` `file_thp`) with their dirty and writeback bytes, khugepaged's collapses and the bytes their cgroup wrote (`io.stat`, the most any one device saw: a mirror and its members each count the same write) |
 
 ## Tests
 
 `go test ./...`: the tool over a stand-in tree holding the control node's own files of 2026-10-14; the
-manifest's shape (the default, the order, the unit and its sandbox, reload, restart and health); and the script as the mesh
+manifest's shape (the default, the order, the unit and its sandbox, reload, restart and health); the boot-entries script run with `sh` over stand-in roots (a systemd-boot entries directory, a GRUB menu, a hook that copies kernels to one fixed name): the entry from the booted command line, a menu generated again only when the kernels changed, no loader, no room, the taken-over hook; `kernel_boot` over the same roots; and the huge-pages script as the mesh
 writes it, run with `sh` against a stand-in directory: it sets and reads back, keeps what it found once,
 rotates the journal once and not for `always` nor while the machine starts, goes straight to a new value on a
 reload without rewriting what it found, gives back what it found and then keeps nothing, refuses a value the kernel
