The 2026-10-22 audit found the live socket on *:9835: #373 bound
node/smartctl in monitoring.nix, but the nvidia exporter enabled in
hardware-nvidia.nix kept the nixpkgs default, so the socket-level
defence-in-depth layer never existed for 9835.
Extend the security-exporters eval check to every enabled exporter's
listenAddress so a future exporter without a bind fails the test.

The etcd client API listens on the masters' static LAN address, and the
pod-source deny lists omitted it. Add 2379 to both nft drop lines and
assert it in the security-k3s-pod-firewall eval test. 2381 (etcd
metrics, scraped by in-cluster monitoring) stays reachable by design.
Pairs with the matching Cilium egressDeny port in k8s-gitops.

The DPMS wake failure is the monitor no-signal auto power-off (HPD cycling during idle), not the refresh rate: the 120 Hz pin did not fix it. Disabled in the OSD and recorded as WA-041; pin 144.000 explicitly so niri stops silently falling back.

The 4090 reports the panel 120 Hz mode as 119.880, not 120, so niri fell back to 144 Hz; that DSC link stays dark after a DPMS wake.

The lock bump moves the input from 47c813c to b8e30ec. The guide now says which Nushell the bundle builds against and that its pin warns on divergence, names direct script execution as the replacement for a refused shell handoff, and uses a Nushell stderr redirect in the verification snippet.

Without it mihomo skips the TUN's v6 half when no NIC has an IPv6 address at startup, yet still installs its strict-route v6 blackhole, which locks the host out of IPv6.

No host defines a *-nixos-tests output; the pod firewall drops 5900-5903
from pod sources; the mihomo core keeps geodata and cache in its
StateDirectory; WA-020 was used twice and the cited WA-028 had no row.
microvm.nix's sshSwitch step runs nix-store --load-db against the guest's
read-only virtiofs /nix/store and dies there, so the recipe installs the
runner on the physical host and restarts microvm@<guest> instead.
Clause-level extensions only, no new sections. Publishing gains modals in both directions: the old sentence read as forbidding pushes to the user's own private repositories while leaving the disclosure direction a preference. The diagnosis scenario moves to Smoke because a cross-cutting rule has no area for the Extended trigger to select, and the guide separates cheap checks from behavioral runs so a modal-only edit does not cost a scenario suite.
Restore the IPv4 pin removed by 1e6702db (feat(mihomo): answer AAAA and keep the tailnet off the TUN). Fake IPv6 SSH connections can authenticate and then hang.
LAN clients using DoH dial the IPs they resolved, and a node may not reach an IP a
foreign resolver handed out. The gateway recovers the name from the handshake; on the
desktop the fake-ip table already names every flow. Its binary is a static release
build, not a package: update it by hand and validate the live config with the new core.
The v6 fake pool is a lookup key, not the egress path, so it can be a public range: the
shipped ULA default reads as "local" to browsers and prompts for local-network access on
every site. The gvisor stack override goes with it -- mips is upstream's default, and
nftables rules out the kernel stack here.
`just mihomo-gen` runs generate.nu from the module and validates with the core
the service runs. ~/.config/mihomo keeps only sources.yaml and config.yaml.
fake-ip needs one pool per family, and the family a client picks does not pick the
egress family. Exclude the cluster ULA and the Tailscale ranges from the TUN; the ssh
pin and the WA-028 record cover the fake-AAAA stall.
The ISP retires delegated prefixes, so a guest that registers its WAN prefix
loses it and Cilium never refreshes the node address. Derive the identity from
the IPv4 octets inside fd05:5::/64 and trust that ULA in the guest firewall.
The abort needs havePrivateMountNs == false AND /nix/store still ro:
remountReadOnlyWritable() returns early while the store is writable. Nix
<= 2.34 left it rw until reboot; 2.35 remounts in a private namespace, so
only a freshly booted host hits it. The repro command also uses an open-only
exec 7<..., since cat fails on the read even when the open succeeds.
While here, trim the comments and drop the disabled default_deny/nix
policies plus the explicit killUnconfinedConfinables=false (nixpkgs
default). 82 -> 34 lines.
`just test` has enforced the suite result since #350: the recipe raises unless
`evalTests` is `true`, so a zero exit already means pass. Update the places that
still described the old raw-`nix eval` behaviour: AGENTS.md, README.md,
SECURITY.md, outputs/README.md, and the nix-config-debug / nix-config-new-host /
nix-config-update skills.
The exit-0 caveat is kept only where the raw `nix eval .#evalTests` command is
documented, because that command genuinely exits 0 even on `false`.
Nix 2.35's root nix-env -- used by nixos-rebuild to set the system profile --
calls saveMountNamespace(), which opens /proc/self/ns/mnt before remounting
the read-only /nix/store writable. Those magic links have no connected path,
so AppArmor cannot match them against any rule and denies the open with
EACCES even in complain mode. The private mount namespace is then never
created and nixos-rebuild aborts with:
cannot remount "/nix/store" writable: not in a private mount namespace
Adding flags=(attach_disconnected) lets AppArmor re-root those paths on / so
the existing `file /**` rule matches. This also fixes any other sudo'd tool
that needs namespaces (unshare, nsenter, bwrap, ...).
Rolling this out to a host that already has the old profile loaded needs one
deploy with --no-reexec, so the current system's Nix performs nix-env --set
instead of the new system's; after that generation is active, plain
`just niri` works and the Nix version is never rolled back.
Gitee's SSH gateway intermittently accepts the connection and key, then never
answers the initial git-receive-pack and drops the session ~100s later with
"the remote end hung up upon initial contact". The same failure mode shows up
sporadically since 2026-10-02 and spiked on 2026-10-07 (9 of 14 runs failed).
Bound each push attempt with `timeout`, retry up to six times with exponential
backoff, and add ssh connect/keepalive timeouts. Serialize runs (a push to main
and a tag on the same commit used to race for Gitee's per-repo push lock), cap
the job at 30 minutes, and allow manual workflow_dispatch reruns.
Every remaining pkgs-x64 consumer runs only on x86_64-linux hosts, where the
native pkgs already carries the same allowUnfree config
(modules/nixos/base/nix.nix) and overlays (modules/base/overlays.nix), so
replace the references with pkgs and drop the extra nixpkgs instantiation
(which also removes an eval on aarch64-darwin).
media.nix keeps the native Zoom app on x86_64 hosts only, since zoom-us has
no aarch64 Linux build.
Apple Silicon's 16K pages mean FEX cannot run natively and qemu-user cannot
run complex x86_64 binaries. Wire the maintained rowanG077/nix-x86-on-aarch64
runtime (FEX inside a 4K muvm microVM) into shoukei so games, Steam, Wine and
other x86/x86_64 programs work, and let the module own the x86 ELF handlers
instead of qemu-user.
The input is pinned to our fork (ryan4yin/nix-x86-on-aarch64) at the reviewed
commit. Dropping boot.binfmt.emulatedSystems also removes x86_64 from
nix.settings.extra-platforms, so the qemu-user/uncached-x86-build gap is
recorded as WA-022.
- flake.nix: add nix-x86-on-aarch64 input (WA-021)
- hosts/12kingdoms-shoukei/game/: programs.x86-on-arm + steam/wine, 6 GiB VM

KubernetesApiServerLatency fired continuously on the p99 of
apiserver_request_duration_seconds_bucket. Every firing series was
verb="GET", subresource="openapi/v3" (kubelet, kube-controller-manager,
kube-scheduler, apiserver) at ~8s, while real verbs (POST/LIST/DELETE)
stay around 0.2s.
openapi/v3 is a streaming discovery endpoint, like WATCH, so exclude
subresource=~"^openapi/" from the rule.
The bring-up runs at the default 1.25 V; afterwards Gear mode is set to
Gear2 and VDD/VDDQ are raised to 1.28 V, changing nothing else. 1.29 V and
up do not train. Also record that the 1.25 V config passed stressapptest
but still hard-froze under a real llama.cpp load, so a passing test is not
proof of stability.
- replace the btop screenshot with the 2026-10-06 annotated capture
(btop + fastfetch + the strata/llama.cpp serving logs); the old
2026-10-01 file is gone, so the README link moves to the new name
- drop the Helix/AI-agents screenshot and its README reference
- fix stale hardware descriptions: the hosts/README.md inventory row and
the idols-ai header comment still said i5-13600KF, and the zswap pool
comment sized its percentages against the old 96G of RAM (now 128G)
- record the hardware history: the platform was rebuilt on 2026-04-27
(PR #257/#258) onto the Colorful CVN Z890 ARK FROZEN + Core Ultra 7
270K Plus, replacing the MSI board and i5-13600KF the host was added
with in 2023-05; the 2x48G kit predates that rebuild, the 2x16G kit
was added 2026-10-06
- make the DIMM bring-up order mandatory and record its failure mode:
with the 48G pair in first, or all four DIMMs from the start, the
board does not POST
- gloss the Chinese BIOS labels in English, marked as translations of
the labels rather than the firmware's own English wording
Left alone on purpose: the 96G swapfile in hosts/idols-ai/disko-fs.nix.
It was grown from 20G to 1x-RAM on 2026-10-02 (a26ab3be), when the host
still had 96G; resizing it again means re-running disko on the machine,
so that stays a separate decision.
dsh keeps its session transcripts, workspace storages, and profiles in
DSH_HOME=~/.dsh, which was outside the backup allowlist. Exclude its
.credentials.yaml like the module's other credential paths.
Explicit session action lists replace the built-in defaults, so re-declare all
five actions; lock stays immediate, logout/suspend/reboot/shutdown arm a 10 s
countdown that a second press runs immediately.
QT_QPA_PLATFORMTHEME=gtk3 (from #386) made Qt derive its color scheme
from GTK3, which has no dynamic dark/light signal, so Telegram and other Qt
apps were stuck on the light palette after Noctalia's theme mode changed.
Use the portal theme instead: Qt then follows
org.gnome.desktop.interface color-scheme, which Noctalia writes. The trade-off
is Qt's built-in "Sans Serif" 9pt font, which a font-providing platform theme
would be needed to change.
go-musicfox posts its own desktop notification on every track change and both popups sit at bottom_right, so the media OSD was a second, redundant popup.
Clear AltTriggerKeys, whose Shift_L default toggled on left Shift. Left Shift is now a plain modifier and right Shift switches through the shared Rime config.
Pin keyd's right-hand modifiers (rightcontrol/rightshift/rightmeta) to their own keycodes; keyd otherwise folds them into the left keys. Set Vinput's MenuKey to right Ctrl and clear CommandKeys, which would shadow it.
