* chore(nix): update nixpkgs to e62746b and fix 26.11 breakage
Bump nixpkgs to e62746b and preservation to 00be7f7, then adapt to the removals and renamed options in the new revision: drop the removed boot.initrd.systemd.enable settings, trim the stale emSign CA blacklist on Linux while keeping it for the older Darwin input, and migrate Avahi publishing to settings.publish. Work around sunshine still setting the legacy Avahi options and keep dsh-nu on its tested Nushell 0.115.1. Patch NUR dsh's pnpm call to pass nodejs = null, and update pyclipsync for the stdenv.hostPlatform.system rename.
* chore(nix): refresh flake inputs for 26.11
- update nixpkgs-darwin to the same e62746b revision as nixpkgs
- make dsh-nu follow main nixpkgs and patch its testedWith manifest for the resolved Nushell
- refresh floating inputs; update lanzaboote, tuios, and ponytail
- drop the nixpkgs-2505 and rust-overlay workarounds
- keep pyclipsync on main and simplify the cross-platform CA blacklist
- adopt home-manager's Nushell loadSessionVariables default
* fix(gitea): use ROOT_URL for nixpkgs 26.11
nixpkgs removed the legacy settings.server.DOMAIN option; the existing ROOT_URL already carries the public URL.
* chore(nix): update dsh-nu to 0.7.0

Reading the host's install script evaluated each guest, which pulls the private secrets input, so

* docs(agents): wait for CI in the background
Pushes to a PR often start multi-minute CI runs, and an agent that holds
the turn open on a foreground watch reports nothing until it ends. Require
the pushed head and running checks to be reported first, the watch to run
in the background, and the result to be collected after independent work
or after ending the turn.

* docs(agents): keep the shell-handoff rule platform-neutral
The global rules carry no Windows assumptions: drop the cmd, pwsh, and
wsl handoff examples and keep the POSIX forms plus the dsh refusal.
Assisted-by: DeepSeek Harness (deepseek-flash)
* docs(dsh): keep the shell-swap docs POSIX-only
This repository manages Linux and Darwin hosts, not Windows: drop the
Windows handoff examples and terminal-backend wording from dsh.md. The home
patch also disabled pwsh-sandbox redundantly because dsh-base already
disables that row on POSIX; keep only the active bash-sandbox disable and
verify the composed rows with --dump-config.

* docs(agents): keep the global rules runtime-neutral
Global rules are loaded by every agent CLI, so they must not describe one
runtime's behavior. Drop the dsh-specific sentence and wording while keeping
the expectation to prefer Nushell structured pipelines and Python. Runtime
behavior stays documented in home/base/tui/agents/dsh.md.
Assisted-by: DeepSeek Harness (deepseek-flash)
* docs(agents): default shell work to Nushell
Keep the Nushell preference explicit in the runtime-neutral global rules, and
keep runtime behavior in runtime docs. Bash stays a narrow fallback for tasks
Nushell cannot do.
Assisted-by: DeepSeek Harness (deepseek-flash)
* docs(agents): tighten global-rule scope and CI guidance
Keep global rules runtime- and project-neutral, and state that boundary in the
file. Remove the duplicated CI turn-steering text in favour of the Communication
rule, resolve the watch run before watching instead of relying on
gh pr checks --watch alone, name the working-directory parameter generically,
and distinguish a bounded retry backoff from a fixed completion wait.
Assisted-by: DeepSeek Harness (deepseek-flash)
* docs(agents): never estimate a CI run's duration
A CI run has no predictable length, so do not turn "it looks short" into a
reason to wait. The rule is unconditional: report the head and started checks,
start a background watch, and end the turn; collect the result on completion.
The eval scenario now uses an unknown duration.
Assisted-by: DeepSeek Harness (deepseek-flash)
* docs(agents): move maintenance guidance to the README
The runtime/project boundary is guidance for editing the rules, not a rule
agents need loaded every session. The README's Maintaining global rules
section already owns that audience; the loaded rules keep only behavior.

* refactor(dsh): render the home patch from a YAML template
Move the home-layer cordis patch into dsh-cordis.patch.yml, substitute the
bundle and Nushell store paths with replaceVars, and link the rendered file
through home.file.source. This module is the only writer of
~/.dsh/cordis.patch.yml, the current host has no such file, and the profile
patch is a separate layer.

* refactor(dsh): install the shell plugin through NUR withPlugins
Replace the local runCommand bundle, peer symlink, and home-layer YAML file
with the plugin package and dsh.withPlugins from ryan4yin/nur-packages#43. The
package wrapper adds a generated --patch overlay after the profile layer, so
dsh no longer writes or manages ~/.dsh/cordis.patch.yml. The NUR input is
temporarily pinned to the PR branch and its commit; point it back at main once
the NUR PR merges.

* refactor(nix): expose the NUR package set as nurPkgs
Pass one per-system NUR package set through specialArgs instead of repeating
nur-ryan4yin.packages.${pkgs.stdenv.hostPlatform.system} at each call site.
The agents, rime, and idols-ruby modules now use the short binding.
Assisted-by: DeepSeek Harness (deepseek-flash)
* refactor(nix): use nurPkgs in package overlays

* fix(dsh): pass the web profile explicitly
The withPlugins launcher prepends --patch, which historically prevented dsh
from auto-expanding "dsh web" into "--profile web". Pass the profile
explicitly in the Just recipe and the verification commands so they work with
both plain dsh and the wrapper.
Assisted-by: DeepSeek Harness (deepseek-flash)
* chore(dsh): pick up the wrapped-profile fix
Update nur-ryan4yin to the squash merge that keeps an implicit profile name
first, so "dsh web" and "just dsh-web" work through the wrapper again.

* chore(dsh): pick up the plugin peer-link fix
Update nur-ryan4yin to the squash merge that links the dsh peer tree at
node_modules/@deepseek-ai instead of nesting it one level deeper. This is the
import failure that stopped nushell-executor from activating after deploy.

* feat(aquamarine): make the iGPU usable for media and OpenVINO
The R9700s stay reserved for inference: VA-API/QSV transcoding moves to the iGPU media
engine, and `openvino-gpu` works around ROCm's OpenCL loader shadowing the plugin's
`ocl-icd` (WA-038).

* docs(aquamarine): document OpenVINO on the iGPU

The goal is speech recognition on the NPU for vinput, and sherpa-onnx cannot
deliver it: every model it loads keeps a dynamic time axis, which the NPU
compiler rejects outright. Qwen3-ASR and SenseVoice both core-dumped in
vpux-compiler ("Got non broadcastable dimensions pair"), and reshaping the ONNX
inputs does not help because the dynamic dimensions sit inside the graph
(WA-037). Whisper is the only family OpenVINO publishes fully static IRs for,
and its fixed 30 s window is exactly what the compiler accepts.
The host now runs an OpenAI-compatible /v1/audio/transcriptions service backed
by whisper-large-v3-turbo int8 on the NPU: 1.5 s for 11 s of audio against
2.1 s on CPU, with the compiled graph cached in /var/cache so only a cold cache
pays the ~60 s NPU compile. vinput on the desktop sends raw PCM to it through a
small provider script.
Only the NPU driver and compiler still come from the unmerged branch in the
`nixpkgs-npu` input (NixOS/nixpkgs#570230), whose nixpkgs also happens to be
the one where openvino-genai 2026.4.0.0 builds at all.

On a tmpfs root the flake/fetch cache is empty at every boot, so

* flake.lock: Update
nixpkgs only. The new revision builds VictoriaMetrics with cgo
(CGO_ENABLED=1); its pure-Go zstd decoder rejected a stored values block, so
every small-part merge panicked on youko.
* fix(colmena): address the VM hosts by name, not by their IP
`~/.ssh/config` pins the passphrase-protected builder key with IdentitiesOnly
for 192.168.*, so IP-addressed ssh cannot authenticate without a terminal. The
name resolves through the aliases in /etc/ssh/ssh_config.
* fix(monitoring): repair two alert rules VictoriaMetrics rejects
`on(uid)` matches on a label kube-state-metrics no longer emits, and
`!= ON(__name__, instance)` treats every pg_settings series as a duplicate.
They now join on (namespace, pod) and compare with `changes(...[5m])`.
* fix(monitoring): keep disk latency alerts off mechanical disks
Both rules averaged per-op latency with no device or sample guard, so the 4 TB
USB HDD volumes paged constantly (>100 ms/write in 26% of the last 30 days).
They now require a non-rotational physical device and >=5 ops/s.

* fix(microvm): pin guest IPv6 identity to a cluster ULA
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.
* feat(mihomo): answer AAAA and keep the tailnet off the TUN
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.
* feat(mihomo): generate the config from the repo, not a copy in the live dir
`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.
* fix(mihomo): keep the fake IPv6 pool out of fc00::/7
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.
* feat(mihomo): sniff on the gateway, not on the desktop
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.
* fix(mihomo): name the Singapore nodes instead of matching 新
The single-char keyword also matched 新西兰, so the Singapore group held a New
Zealand node and url-test flipped the exit country mid-session.
* feat(mihomo): keep ranges that can never be proxied out of TUN
The list lives in policy.yaml as tun_exclude_address; sources.yaml may override
it. 198.18.0.0/15 stays in TUN: that is the fake-ip range itself.
* feat(mihomo): match Valve's content servers by ASN
The 20 hand-copied prefixes had drifted from what AS32590 announces. The rule
type needs GeoLite2-ASN.mmdb, so geox-url.asn points at the same mirror.
* feat(mihomo): render the gateway config from the same sources
The hand-kept copy had drifted: a manual sync carried the desktop's secret onto
the gateway and dropped external-ui-url. --redact yields a shareable template.
* fix(mihomo): open the link DNS takeover only once the core serves it
The core opens :1053 after parsing rules, and rule parsing is where missing
geodata gets fetched. Flipping at fork time made that fetch SERVFAIL, the config
fatal, and the unit unstartable.
* fix(justfile): keep local endpoints out of the agent proxy
With only HTTP_PROXY set, a request to this host's own llama-swap endpoint went
to mihomo. Node matches exact hosts only, so the literals carry it; the CIDRs
serve curl and Go.
* feat(justfile): seed mihomo geodata into the service state dir
So a cold start never needs the download that the DNS takeover made unstartable.
The comment trim dropped them. Without a domain rule above the Valve IP ranges,
steamcommunity.com and steampowered.com match those ranges and go DIRECT.
Steam picks download caches from the IP it sees on the CM login. Pin the CM hosts
and content CDN DIRECT, keep the community and store proxied, and add Valve's
AS32590 ranges because Steam dials cached CM IPs without a lookup. Sources in
README.md.
BCM4378/brcmfmac intermittently fails Wi-Fi association (ASSOC-REJECT /

as a bad key and re-prompts; whichever client reconnects (Noctalia, nmtui,
nmcli) then saves the answer as a duplicate "<SSID> 1" profile. The problem
predates the Noctalia v5 shell and is driven by the driver, not the shell.

* feat(shoukei): run x86/x86_64 apps and games via muvm+FEX
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
- hardware-configuration.nix: drop emulatedSystems/preferStaticEmulators

* refactor(nixpkgs): drop the repo-wide pkgs-x64 package set
Every remaining pkgs-x64 consumer runs only on x86_64-linux hosts, where the
native pkgs already carries the same allowUnfree config

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.

The Telegram channel was dominated by alerts that can never be actionable:
- DriveTemperatureHigh/Critical did not filter temperature_type, so
max(smartctl_device_temperature) picked the drive's rated
op_limit_max/critical_limit_max instead of the actual reading. ai reported
95 C and youko 130 C while the drives actually ran at 40-48 C.
- HostPhysicalComponentTooHot excluded label!="tctl", but the AMD k10temp
hwmon sensor labels itself Tctl, so the CPU control temperature (up to
~100 C under load) tripped the alert on every AMD host.
- MicroVM guests share the host's read-only /nix/store, so their
nix-gc.service always failed and tripped HostSystemdServiceCrashed on all
six k3s guests. Disable automatic GC in the guest; the host's nix.gc
reclaims the shared store.
The remaining k3s alert noise comes from workloads running on the masters
that belong on the workers; that is fixed in k8s-gitops, not by resizing
the control-plane VMs.

`dsh-llm-pi-ai` registers its built-in providers once, so a second instance
in the profile patch fails on mount with `provider "..." is already declared`.
Extend the base `llm-pi-ai` row instead.
dsh rewrites a profile's cordis.patch.yml at runtime, so linking the web
profile put GUI state in the checkout and let runtime writes clobber manual
edits. Link the stable policy as the $DSH_HOME home layer instead: dsh applies
it after every profile and only reads it.
The host-plane compaction-basic row is disabled on the web surface and each
agent preset owns its own copy, so the top-level override was inert. Drop it;
the model contextWindow/maxTokens are the effective knobs.
- add home/base/tui/agents/dsh/cordis.patch.yml, linked from default.nix
- drop the ~/.dsh/profiles/web link and the tracked web/ profile
- keep runtime state and private/local model routes in the profile patch
- update the eval test and README
* feat(rime): share the Rime config and user dictionary across Linux and macOS
Move the Rime data, preferences, and user dictionary into home/base/gui/rime so fcitx5-rime and Squirrel read the same files.
* feat(vinput): open the command palette with right Ctrl
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.
* feat(fcitx5): switch CN/EN with Ctrl+Space and right Shift
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.
* fix(desktop): align Qt app fonts with GTK
Qt apps kept their built-in default font ("Sans Serif" 9) while GTK apps use
`gtk-font-name` (Noto Sans 11), so Telegram and other Qt apps rendered
noticeably smaller than GTK apps like Firefox. Set
QT_QPA_PLATFORMTHEME=gtk3; the plugin ships with qtbase, so it needs no
extra package and also gives Qt apps GTK file dialogs.
* chore(desktop): drop unused Xft.dpi from the Wayland GTK profile
Xft.dpi/ *.dpi are X11 X-resource settings. This file is only imported by
the niri (Wayland) hosts, where xwayland-satellite sets its own Xft.dpi
(96 x output scale, currently 144), and the i3 hosts are headless 1080p
computer-use sessions that do not import it. So the setting had no effect
anywhere; remove it instead of keeping a misleading knob.
Vinput's streaming Zipformer models have unbounded dynamic shapes, so
OpenVINO cannot compile them for the GPU or the NPU; the `openvino`
provider and ai's Intel NPU enablement could never run on the NPU (noted
as unverified in WORKAROUNDS WA-017). Remove the backend option, the
daemon's OpenVINO library path, and the intel-npu module enable, and
update the eval test, README and WORKAROUNDS (drop WA-016 and WA-017).
Keep Vinput's stock package and its bundled sherpa-onnx (1.13.4): the
fork-based and nixpkgs-master sherpa overrides existed only to provide the
`openvino` provider, so drop package.nix with them.

metacubexd hardcodes its tab title in the SPA, so dashboards on
different hosts are indistinguishable. Patch the static <title> and
re-apply the hostname from config.js, since Nuxt's useHead resets
document.title on every route change.
The config deliberately stays out of the store, under the home directory, which is a persistent bind mount on tmpfs-root hosts. When the service and the mount are introduced in the same activation, mihomo can start before the mount is up and fail with "Failed to set up credentials: No such file or directory", making the switch report status 4. Add RequiresMountsFor so the mount is brought up and ordered before the service.
Vinput stores its core config in ~/.config/vinput/config.json and its
downloaded sherpa-onnx models in ~/.local/share/vinput/models/. Neither
was bind-mounted from /persistent on the tmpfs-root hosts, so a reboot
wiped both and vinput-daemon started with "Local ASR provider model is
not configured". Persist both directories and document the one-shot CLI
model setup in the vinput README.
* fix(desktop): tie ai's link DNS takeover to mihomo's lifecycle
sing-tun normally points systemd-resolved at the TUN DNS by running
resolvectl (dns/domain/default-route). Under nixpkgs' hardened
DynamicUser mihomo unit that hand-off fails silently: the unit's
RestrictAddressFamilies blocks resolvectl's D-Bus socket and resolve1
requires privileged authorization, so resolved keeps querying the
physical-link DNS, fake-ip is bypassed, and domain rules degrade to
MATCH.
Do the hand-off as '+' ExecStartPost/ExecStopPost hooks instead: '+'
commands run outside the sandbox (systemd.exec: address-family
restrictions do not apply to them) and ExecStopPost reverts even on
crashes, so a dead mihomo leaves DNS usable.

* refactor: consume computer-use packages from NUR
* fix: expose flake inputs to package overlays
Package overlays are imported from two places with different argument
shapes: outputs/default.nix passes a set containing `inputs`, while
modules/base/overlays.nix passes the NixOS module args, where genSpecialArgs
spreads each flake input as a top-level argument. The new NUR-backed
overlays read `inputs.nur-ryan4yin`, so evaluation failed on the module
path. Also expose the whole flake input set as `inputs` in genSpecialArgs.
* chore: bump nur-ryan4yin input
Update the locked nur-packages revision to the current main (nixpkgs
26.05, unused packages removed).
node_exporter listened on 0.0.0.0, so access control rested entirely on
the nftables allowlist. Bind node/smartctl exporters to the host static
LAN IPv4 (the same address VictoriaMetrics scrapes), keeping the socket
off tailscale/bridge interfaces even if the firewall regresses.
Hosts without a static LAN address (shoukei, akane) now run no exporters
at all instead of loopback-bound ones nobody scrapes; akane, a UTM VM,
previously ran a loopback smartctl exporter with no physical disks.
LAN-bound exporters also get the boot-race treatment from #372
(network-online ordering plus patient restart); loopback-bound hosts
must not pull in network-online because NM wait-online would stall
their offline boots.
The exporter binds to the host LAN address, which systemd-networkd
assigns during boot. Without ordering, the service starts before the
address exists, `bind: cannot assign requested address` trips the
start limit, and the unit stays failed until restarted manually.
Order the unit after network-online.target, and since wait-online is
best-effort (120s timeout), also retry patiently so the unit self-heals
when the link comes up late.
Add SECURITY.md covering the threat model, trust boundaries,
proportionate kernel/process hardening, the update/reboot routine and
remaining prioritized work. Record the dated read-only audit findings
(listeners, privileged workloads, effective RBAC, secret metadata and
sandbox/SSH boundaries) separately from planned controls and runtime
verification.
Define agent-first diagnosis: scoped root read-only access on homelab
hosts, and normal-user diagnostics on core desktops with no new sudo
grants. Add canonical domain-based k3s API endpoint regression tests,
record the unverified Darwin secret-ownership concern as WA-015, and
correct comments claiming mode 0000 blocks privileged root.
test-instrumentation.nix sets serial-getty@ttyS0.enable = false at normal priority to keep ttyS0 free for the test backdoor console, while qemu-guest.nix set it to true at normal priority. Two conflicting normal-priority definitions made `nix flake check` fail while evaluating packages.x86_64-linux.ruby-nixos-tests.
Use lib.mkDefault so the test framework wins in tests while ordinary QEMU guests still enable the serial getty.
