The cherry-picked openvino 2026.4.1 bump (upstream PR #564046, still
unmerged) made onnxruntime 1.27.1 fail its OpenVINO EP MatMulNBits
numerical test, breaking sherpa-onnx and the ai-niri system build.
The fork branch now stays at upstream openvino 2026.4.0.
Restore the rule dropped in 9822dafa: keep GitHub Git remotes on SSH, make sure the Nix-managed ~/.ssh/config is used, and rerun outside the sandbox when it is rejected.
Move the flypy schema data to the rime-data-flypy package in
ryan4yin/nur-packages and keep only the personal user dictionary
(flypy_user.txt) here. The overlay merges the NUR data with that file
and exposes the result as pkgs.rime-data, fcitx5-rime's rimeDataPkgs,
and pkgs.flypy-squirrel.
* 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).
Kimi Code moved its desktop client into an internal repository in July 2026 (MoonshotAI/kimi-code#1849), so the polished surface is no longer open source; the CLI that stays behind overlaps opencode2 and pi. Removing it drops one more redundant harness.
oh-my-pi is a feature-complete superset of pi, so its role is already covered: opencode2 for a batteries-included harness, pi for the minimal/local-model one. Keeping it meant maintaining two nearly identical harnesses.
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.
The optional kernel reboot-visibility change was closed without merging, so remove the planned-reporter wording. Replace it with the manual booted-vs-selected kernel check and update the P1 TODO accordingly.
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.
muvm is disabled because it does not build/run on nixos-apple-silicon yet, not because of a permanent hardware limitation; the 16k page size is the reason it is wanted, and the removal condition is muvm building and working.
WORKAROUNDS.md collects temporary workarounds, version pins, carried patches, and known gaps, each with a removal condition, so they can be re-evaluated and rolled back on a schedule. AGENTS.md points to it and states the convention: a change that adds a workaround adds a row in the same PR.
Replace the backported patch with a src/version/vendorHash override that pins prometheus-smartctl-exporter to upstream 6274decc (2026-09-28), which already carries the Describe() fix from PR #329. Simpler to maintain than a patch file and it tracks the upstream change directly; drop the overlay once smartctl_exporter 0.15.0 is packaged in nixpkgs.
smartctl_exporter 0.14.0 derives Describe() from the devices it can read at startup. A device that only becomes readable later (an NVMe whose ACL arrives late, or an HDD waking from standby) then makes Collect() emit metrics with unregistered descriptors, so /metrics returns HTTP 500 and the whole scrape fails, hiding even the healthy disks.
Backport upstream PR #329, which makes Describe() send the full explicit descriptor set. Carry it as an overlay until smartctl_exporter 0.15.0 is released and packaged in nixpkgs.

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.
* fix(colmena): expose colmenaHive for the new evaluator
nixpkgs now ships the nix-community Colmena rewrite, whose default
evaluator reads an evaluated colmenaHive flake output instead of the raw
colmena hive. Without it every colmena apply recipe failed with
"does not provide attribute colmenaHive".
Add a colmena input pinned to the same v0.5.0 as nixpkgs and expose
colmenaHive = colmena.lib.makeHive <raw hive>, with the raw hive kept as
an internal binding rather than a flake output of its own.
* chore: clean up stale colmena and aquamarine references
- point the Colmena links at nix-community/colmena after the move
- rename the security-aquamarine-metrics test to youko-metrics (it
already tested youko) and update the outputs README
- drop the commented aquamarine remote-builder example
* chore(workarounds): re-evaluate stale hardware/kernel fixes
Prune workarounds whose root cause is gone, fix one vendor typo, and
document the ones we keep:
- drop `transparent_hugepage=madvise` on shoryu/shushou/youko: it was tied to
the old fixed 1G hugetlb pool, and the VMs now use ordinary memory
- shoryu: `hardware.cpu.intel.updateMicrocode` -> `amd` (it is an AMD APU)
- ai: drop `i915.enable_guc=3` (GuC/HuC submission is the default on modern
i915/Xe)
- kernel-hardening: name the Dirty Frag CVEs (CVE-2026-43284 / CVE-2026-43500)
and the re-evaluation condition
- document re-eval conditions for the Insta360 resume fix, the darwin
auto-optimise-store workaround, and the youko USB-SATA bridge mitigations
* chore(workarounds): keep the Dirty Frag module blacklist as defence in depth
* chore(ai): correct the i915.enable_guc rationale (verified against the kernel)
* chore(darwin): drop the auto-optimise-store workaround (nix#7273 fixed)
* fix(ai): relax NVMe power-management workarounds and enable smartd
Logs show no NVMe errors, so allow APST again (capped at 100 ms), restore
the default io_timeout, and drop pcie_aspm=off. Add smartd for drive
health visibility.
* feat(storage): add drive/SSD SMART monitoring on physical hosts
node_exporter's nvme collector only exposes node_nvme_info and namespace
capacity, not SMART health, so SSD wear/lifespan and drive temperature were
not observable anywhere.
- enable services.prometheus.exporters.smartctl on physical hosts, gated on
modules.hardwareTools (off on QEMU/MicroVM guests), bound to the host's LAN
address on port 9633
- firewall: drop 9633 from anything but the monitoring host
- youko: scrape smartctl-<host> for the physical hosts
- alert rules (storage.yml): SMART health, NVMe wear, available spare, media
errors, critical warning, and drive temperature (warn 70 / crit 80 C)
- Grafana dashboard "Drive SMART (smartctl)"
agenix was pinned to a May 2025 revision, so `just up` could never move
it. Move to the 0.18.0 release tag and collapse its duplicate
nix-darwin/home-manager lock nodes via follows.
Remove a dead .gitattributes rule, bump the mirror workflow's checkout,
document the daemon test settings, drop unused JACK, and align the
installer's disko version.
* fix(ci): fail the eval-test run when the suite does not pass
`nix eval .#evalTests` prints the suite result but exits 0 either way, so
both `just test` and the CI workflow reported success even when a test
failed. Compare the raw boolean and fail instead.
* fix(ci): use --json for the boolean eval result
`nix eval --raw` cannot coerce a Boolean to a string, and Just runs each
recipe line as a separate `nu -c`, so the result variable must stay on one
line.
* feat!: replace zellij with tuios and switch to ghostty + kitty
Terminal environment overhaul:
- add the tuios flake input (upstream 0.8.5; nixpkgs has 0.8.1) and link
the checked-in config out-of-store; auto-start tuios in nushell instead
of zellij
- remove zellij entirely: both modules, config, README and nushell
completions
- remove foot and alacritty, which lack the Kitty graphics protocol;
