New on-site host mars runs Hermes Agent as its sole service: joins the
tailnet, mounts jupiter's samba share at /mnt/jupiter (doubling as
Hermes's shared dropbox), and hosts state locally under /var/lib/hermes.
Same Authentik OIDC app/Telegram bot as before, just relocated — neptun's
hermes.mgaction.town vhost now points at mars.orbit.sol instead of jupiter.
hosts/jupiter/hermes-agent.nix and its three sops secrets are removed;
jupiter's Caddy vhost for it is gone too. Also refreshes tailscale_authkey
across all hosts and fixes two stale "erik@laptop" keys in flake.nix's
kexec/installer-iso images (leftover from a previous laptop, already
swapped out of common.nix back in 2fd5752) to darman@terra.

Points Nous Research's Hermes Agent at terra's own ROCm ollama server
(gemma4:12b) as a custom OpenAI-compatible provider instead of a cloud
key. Native systemd mode via the hermes-agent flake's own NixOS module
— simpler than container mode, avoids the podman-rootful-sudo dance
its docs call out.
Also bumps OLLAMA_CONTEXT_LENGTH (and Hermes' mirrored model.context_length)
from ollama's ~4k default to 131072, load-tested with real multi-ten-
thousand-token prompts rather than just idle `ollama ps` checks — chosen
as the practical ceiling where VRAM headroom and prefill throughput both
start visibly degrading, not just the largest number that technically fit.

Local LLM server on the 6800 XT (ollama-rocm, gfx1030 needs no
HSA_OVERRIDE_GFX_VERSION) fronted by a LibreChat web UI, talking to it
over the OpenAI-compatible /v1 route. Also wires up LibreChat's
persistent-memory feature, which needed its own agent+model plus a
custom extraction prompt: the default 3b model couldn't reliably tell
the user's stated facts apart from its own boilerplate, and even a
tuned prompt didn't fix that — so memory extraction now reuses
gemma4:12b, the same model as the daily-driver chat endpoint.
flake.lock bump pulls in the ollama and librechat NixOS modules.

Tome (formerly AudibleLibrary) comes back as a git+ssh input against our own
gitea, fetched with darman's ambient key. `flake = false` — it's a plain
source tree consumed by pkgs/tome.nix, not a flake of its own.
This re-breaks `./scripts/deploy install terra localhost` exactly the way
4f79ec7 removed it for: the installer-iso has no credentials, so the git+ssh
fetch fails at nixos-install, post-disko. Taking that tradeoff knowingly
rather than losing the app from the desktop config again — the note in
flake.nix spells it out for whoever hits it next.
The lock also picks up the routine input refresh, including the nixos-26.05
rev that finally carries the tailscale vendorHash fix (next commit) and a new
client-ts-generator-src node pulled in by authentik-nix.

Own Hyprland plugin (border + title bar), public repo on our own gitea,
fetched over https (no credentials needed). nixpkgs.follows keeps its build
ABI-correct — Hyprland plugins are ABI-locked to the exact Hyprland build
they load into, so it has to build against this flake's own nixpkgs rather
than whatever hypr-chrome's own flake.lock pins standalone.
- Hyprland workspace rules: start-communications.sh launches telegram +
discord into special:communications; qbz/discord/telegram switched to
flatpak (nix-flatpak, Flathub) — removes qbz and proton-pass-cli flake
inputs
- proton-pass-cli and claude-code sourced from nixpkgs-unstable; unstable
pkgs set threaded into home-manager via extraSpecialArgs
- GTK/libadwaita dark theme fixed: dconf color-scheme = prefer-dark written
declaratively instead of a per-session gsettings call
- scripts/keys: store/restore SSH host keys and sops age keys via Proton
Pass (ssh_host#<config> / age#<config> / age#admin naming)
The `install <config> localhost` auto-path added in 0ea9020 could not have
completed. Fixed three blockers plus the guard that was silently not guarding.
Inside installer-iso the run died before doing anything:
- systemd sets no $HOME for a service without User= (SetLoginEnvironment=
defaults to false), and this script runs under `set -u`, so it aborted on
the bare $HOME with "unbound variable". Added $KEYDIR + Environment=HOME.
- the host key it needs to seed /etc/ssh isn't on the ISO at all — that is
built from a public repo and carries no credentials on purpose. It now
travels on the boot partition, located via homelab.keypart=<PARTUUID> on
the kernel cmdline, and dies with the disko wipe minutes later. Without
it sops can't decrypt on boot #1 and mutableUsers locks darman for good.
- installation-cd-minimal leaves experimental-features unset, so both
`nix run` and `nixos-install --flake` failed. (The nixos-images kexec
installer sets them itself, which is why the same branch worked after
kexec-local but not from the ISO.)
The staging-dir guard passed everything on btrfs: findmnt prints the
subvolume as /dev/sdb2[/@], lsblk can't open that, and an empty parent was
treated as "different disk" — so it allowed staging the iso on the very disk
disko then wiped. terra's current CachyOS root is exactly that layout. Now
uses --nofsroot, resolves EVERY whole-disk ancestor (LVM/RAID span several:
/mnt/ssd_01 -> sdd+sde), and treats "can't tell" as a hard error. btrfs
staging is refused outright — stage-1 mounts a btrfs volume's top level, so
an iso inside a subvolume is unreachable.
findiso= lost its leading slash whenever the staging mountpoint was /,
giving /findisovar/tmp/x.iso and an emergency shell after the reboot.
Also:
- confirm before rebooting, like flash/kexec-local already do; --yes skips
it and is what the ISO passes itself
- $BOOT from `bootctl --print-boot-path`, not a hardcoded /boot
- free-space checks on both target partitions before the ~1GB copy
- `nix run .#disko` / `.#nixos-anywhere` from locked inputs instead of
github:... master-of-the-day, resolved while a disk is being wiped
- one_match warns instead of silently taking [0]; require_tracked covers
every hosts/<config>/*.nix; flash traps its mount
- drop nixos-images' `inputs.nixpkgs.follows` — that input doesn't exist,
it only printed a warning on every nix command
Verified: the prepare path exercised under stubs against this box's real
disks (btrfs-on-OS-disk, tmpfs, LVM, subdirectory), shellcheck clean, all
six configs evaluate, checks.kexec-local still passes.

Tome (née AudibleLibrary) is darman's own Photino/.NET desktop app, private
repo on our own gitea. Fetched as a flake input over ssh with darman's
ambient key — same mechanism as any other git input, private or not.
buildDotnetModule package: the Preact/Vite frontend (Tome.App/ClientApp)
builds as its own buildNpmPackage derivation and gets copied into the
published app's wwwroot, since upstream's in-project MSBuild npm target has
no network access in the Nix sandbox. Photino.Native's runtime deps (gtk3,
webkitgtk_4_1, libnotify) are wrapped in — confirmed via readelf/ldd that
this Photino build already targets webkit2gtk-4.1, not the now-removed 4.0.
Also added dotnet-sdk + nodejs to terra for developing Tome locally, and
vivaldi (unfree, extends the existing allowUnfreePredicate).

Not in nixpkgs; packaged by github:tomsch/proton-pass-cli-nix. Used by

jupiter had a leftover docker-compose Immich on the RAID (/mnt/data/Immich,
9.9G) that survived the NixOS install. Native module now, media at
/mnt/data/AppData/immich, caddy vhost on 2283 with a 50GB body limit
(caddy's default rejects video uploads).
The package comes from nixpkgs-unstable, the module from the 26.05 pin:
26.05 ships immich 2.7.5, but that database was last written by 3.0.0 and
migrations only run forward --
corrupted migrations: previously executed migration
1776217577402-DropAuditTable is missing
Safe because the two module files are byte-identical at these revisions;
services/media/immich.nix carries the diff command to re-check on a bump.
Drop the input once the stable pin ships >= 3.0.0.
immich needs group "users" only to traverse /mnt/data/AppData (drwx--x---);
its own dir stays 0700 immich:immich. mediaLocation is outside /var/lib, so
the module's tmpfiles entry only ADJUSTS it -- add a rule that creates it.
scripts/immich-import-legacy-db does the database half: boots a copy of the
legacy PGDATA under the matching image (PG14 + vchord 0.3.0 + pgvector
0.8.1), dumps it with the local pg_dump 17, restores into a scratch DB,
fixes ownership, and only swaps after confirmation. Never touches the
original. The old cluster ran VectorChord, not pgvecto.rs, so the smart
search and face embeddings survive -- no ML re-run.
Imported: 666 assets, 25 people, 647 clip + 359 face embeddings, 2 users.
nixpkgs only carries Zitadel 2.71, which predates the login-v2 split and
cannot take a v3/v4 database (its migrations are forward-only), so the
instance running on the old Debian VPS could never have moved onto it.
authentik-nix ships 2026.5.4 and tracks upstream closely.
The authentik-nix input deliberately does not follow our nixpkgs, per
upstream's warning that overriding it breaks their pinned python
dependency set. That costs a second nixpkgs in the lock, so add
nix-community's Cachix to common.nix -- without it the closure is ~400
local derivations (npm, rust, python). The laptop that runs
scripts/deploy needs the same two lines in /etc/nix/nix.custom.conf.
Authentik's own module creates the database and orders its units against
postgresql.target, and recent versions need no redis, so the wiring is
just the module plus a secret. Pin postgresql explicitly so that editing
system.stateVersion can never silently demand a pg_upgrade of the
identity store.
Secret ownership is not uniform and the difference matters: authentik
and caddy take a systemd EnvironmentFile, which PID 1 reads as root
before dropping privileges, so root:root 0400 is correct. Headplane
opens its secret paths itself while already running as the headscale
user, so those three need an explicit owner or they fail to start.
Also on neptun:
- Pass Caddy's ACME account email through the same EnvironmentFile
mechanism and reference it with the Caddyfile {$VAR} placeholder.
services.caddy.email would render the address into the world-readable
store.
- Stop accepting MagicDNS from our own control server. headscale pushes
override_local_dns, so joining the tailnet would point neptun's
resolv.conf at a MagicDNS served by the tailscaled neptun itself hosts
-- a tailscaled failure would then also take out DNS, ACME renewal and
finally the certs for the control server every other node needs in
order to recover.
- Give headplane a writable DNS extra-records file. Its view of
headscale's config stays read-only, which is the right outcome for a
declarative box; records are data rather than config.
- Require a password for sudo. Deploys become interactive, but darman's
key is otherwise the only thing between the public internet and root.
- Enable zram (8 GB, and disko leaves no room for a swap device), and let
tailscaled-autoconnect retry instead of failing permanently when the
control server isn't up yet on a first boot.
networking.hosts still carries a PLACEHOLDER address for jupiter --
replace it from `headscale nodes list` once jupiter first enrols.

- sabnzbd, prowlarr, sonarr, radarr, clonarr, seerr, cinephage, mediamanager
services, wired into jupiter with LAN Caddy vhosts.
- Gitea: migrated the old ZimaOS docker instance's data (sqlite db, 4 repos,
no LFS objects) into the NixOS module's default stateDir layout. HTTP via
Caddy; git SSH on its own built-in server at :2222 (not :222 - the unpriv
gitea user can't bind <1024).
- mediamanager-nix flake input for the mediamanager service.

- add nixos-images input; nixosConfigurations.kexec bakes in the ssh login key
- build via config.system.build.kexecInstallerTarball
- deploy: ./deploy kexec <host> streams the installer to /tmp and kexecs
- works around ZimaOS RO root where nixos-anywhere ssh-copy-id fails

- add sops-nix input + module (jupiter only, not the VM)
- secrets/jupiter.yaml: age-encrypted samba_password (safe to commit)
- .sops.yaml: encryption rule for admin age key
- secrets.nix: decrypt samba_password to /run/secrets on the host
- provisioning oneshot reads sops secret (host) or plaintext (VM), single value
- .sops private key stays off-repo (~/.config, /var/lib/sops-nix on host)

- add disko input; jupiter partitions/formats OS disk declaratively
- hardware-configuration.nix carries kernel modules only (disko owns fileSystems)
- data disk stays a plain unformatted mount, out of disko
- vbox unchanged (virtualbox-image supplies its own disk)
- README: nixos-anywhere remote install + daily rebuild loop

- systemd oneshot sets SMB password after samba-smbd (activation ran too early)
- caddy vhost reverse_proxy to whoami so :80 actually serves
- vm.nix: throwaway SMB secret for testing; real host uses sops/agenix
