Conservative reshape coming out of the brainstorm: application-shape
static artifacts move to left4me/deploy/ and are delivered to the
target via bw symlink items pointing into /opt/left4me/src/deploy/...
(safe because the runtime-state relocation made the checkout
root-owned). Per-host shape — base unit bodies, slice CPU pinning,
env templates, nginx/timers/nftables metadata — stays bw-managed in
ckn-bw.
Moves: hardening drop-ins (new), sudoers (dedup mirror), sysctl
drop-in (dedup mirror + absorb ptrace_scope metadata entry),
privileged scripts (relocate scripts/ to deploy/scripts/, replace
install-action with symlinks).
Five-step migration with sysctl consolidation as the canary, then
hardening drop-ins, sudoers, scripts, cleanup. Lands before the
build-overlay-unit refactor so that work can ship its hardening
drop-in inline using this pattern.
