feat(work.nix): source splunk MCP token too

Add programs.zsh.envExtra to the EDaaS work profile so ~/.jenkinsenv is
sourced from ~/.zshenv on every zsh invocation (login, interactive, and
non-interactive), exporting the JENKINS_UCE_/JENKINS_STF_ tokens the Jenkins
MCP servers read via ${JENKINS_*} expansion. Guarded so a missing file does
not break the shell; the file is kept out of the world-readable nix store
because it holds secrets.

-## Docs are checked too
+## Docs are checked too — the common trap
 
 prettier formats `*.md`, so **documentation edits must be run through `nix fmt`**
 exactly like code. prettier re-aligns Markdown tables in particular; hand-editing
 a table almost always leaves it non-conformant and fails the `formatting` check.
 
-Prose documentation lives in `docs/` and is **published** to
-<https://docs.lyrapup.pet/nixfiles/> by the separate `docs-site` repo, which
-clones this one at build time. Two consequences when editing docs:
-
-- A markdown file outside `docs/` (other than the root `README.md`) is not
-  synced and will never appear on the site. Put new prose in `docs/`.
-- Links must follow the rules in the README's "Documentation" section: absolute
-  Gitea URLs to source files, relative links between `docs/` pages, and
-  absolute `docs.lyrapup.pet` URLs from the root README into `docs/`. The site
-  builds non-strict, so a broken link is silent.
-
-The CI `formatting` step runs on **every** PR — including docs- and config-only
-changes — so a Markdown/YAML/JSON edit is format-checked before merge, not just
-after it lands on `main`. (The heavier `deadnix`/`statix`/`pre-commit` lints and
-the per-host evaluation still run only when a `.nix` file, `flake.lock`, or the
-workflow changed; see `.gitea/workflows/ci.yaml`.) Run `nix fmt` before you
-commit and the formatting check stays green.
+Beware a false green: the CI `detect` step skips the heavy checks on a pull
+request that touches **no** `.nix`, `flake.lock`, or the workflow file — so a
+docs-only PR reports success without ever running prettier. The failure then
+surfaces on the push-to-`main` run (which always runs the full check) or on the
+next unrelated PR that does touch Nix. Run `nix flake check` locally before
+merging a docs change, regardless of what the PR check shows.

-## CPU capability gating
-
-Not every host can run everything the fleet installs. Nix cannot probe the CPU
-(evaluation is pure, and a host may be built elsewhere), so each machine
-declares what it is and the shared modules derive from that:
-
-- `features.cpu.microarchLevel` — the x86-64 psABI level the CPU implements
-  (1 = baseline, 2 = SSE4.2/POPCNT, 3 = AVX2, 4 = AVX-512). Defaults to **2**;
-  only a host older than that sets it (the Mac Pro 3,1's 2008 Harpertown Xeons
-  are level 1). Ignored on non-x86_64 hosts.
-- `features.claudeCode.enable` — derived: on unless the host is below
-  x86-64-v2, because Claude Code's Node runtime needs SSE4.2/POPCNT.
-  [`home/claude.nix`](https://code.emmathe.dev/lyrathorpe/nixfiles/src/branch/main/home/claude.nix) reads it through home-manager's
-  `osConfig` and installs nothing (CLI, `CLAUDE.md`, output style, memory
-  symlink) when it is off. Hosts with no such option — the Darwin host and the
-  standalone `homeConfigurations` — fall back to enabled.
-- An assertion in `features.nix` fails evaluation if a host force-enables a
-  flag its declared CPU level cannot support, so the mistake surfaces in
-  `nix flake check`/CI rather than as an illegal-instruction crash on the box.

-Adding another CPU-sensitive tool means deriving one more flag there, not

-## Documentation
-
-All prose documentation lives in [`docs/`](https://code.emmathe.dev/lyrathorpe/nixfiles/src/branch/main/docs); this README is the overview. The pages are
-published to **<https://docs.lyrapup.pet/nixfiles/>** by the
-[`docs-site`](https://code.emmathe.dev/lyrathorpe/docs-site) repository, which clones this repo on
-every build (on its own push, nightly, or on demand) and assembles the tree:
-
-```
-README.md   ->  docs/nixfiles/index.md     # this file becomes the section landing page
-docs/       ->  docs/nixfiles/             # everything here, ordering from docs/.pages
-```
-
-Nothing is pushed from this side and there is no build step here — editing a
-page and merging is all that is required. Files outside `docs/` (bar this
-README) are **not** synced, so a doc kept next to the code it describes will
-never appear on the site.
-
-### Linking rules
-
-The site has no copy of the source tree, and this README is republished at a
-different depth from the rest of `docs/`. Both facts break naive relative
-links, so:
-
-| Link from         | To                      | Use                                                              |

-## Graphics — GTX 1070
-
-Everything driver-related is in [`nvidia.nix`](https://code.emmathe.dev/lyrathorpe/nixfiles/src/branch/main/hosts/Console/nvidia.nix).
-The GTX 1070 is Pascal (GP104), so it is under the same driver constraint as the
-Mac Pro's Quadro P400:
-
-- **Driver branch 580** (`nvidiaPackages.legacy_580`), _not_ the nixpkgs default
-  (`production`, currently 595.x). 580 is the last branch supporting
-  Maxwell/Pascal/Volta, maintained as an LTS branch until Aug 2028; a newer
-  branch does not drive this card at all.
-- `modesetting.enable = true` — mandatory for Wayland. Without
-  `nvidia-drm.modeset=1` neither gamescope nor wlroots gets a usable GBM device,
-  and both the Steam session and Sway fail to start.
-- `open = false` — the open kernel modules require Turing or later.
-- Sway runs with `--unsupported-gpu`; wlroots refuses the proprietary driver
-  otherwise. gamescope and cage/ReGreet need no such flag.
-- `hardware.graphics.enable32Bit` pulls in the lib32 NVIDIA userspace that
-  32-bit Steam titles and Proton's 32-bit prefixes link against.
-
-The driver is unfree, so it is **not in the binary cache**: the kernel module is
-compiled on the machine. On a Haswell i7 that is a few minutes, not the Mac
-Pro's ordeal, but it recurs on every kernel bump. The package names are
-allowlisted in `unfreePackages` in [`flake.nix`](https://code.emmathe.dev/lyrathorpe/nixfiles/src/branch/main/flake.nix).
-
-Verify after a rebuild:
-
-```sh
-nvidia-smi
-lsmod | grep nvidia    # nvidia, nvidia_modeset, nvidia_drm
-```

-## Session model — autologin into Steam
-
-[`gaming.nix`](https://code.emmathe.dev/lyrathorpe/nixfiles/src/branch/main/hosts/Console/gaming.nix)
-sets `programs.steam.gamescopeSession.enable`, which registers a `steam.desktop`
-Wayland session (gamescope wrapping Steam in tenfoot mode) and installs a
-`steam-gamescope` launcher. greetd — already present on every Sway host for
-ReGreet, see [`../../modules/sway.nix`](https://code.emmathe.dev/lyrathorpe/nixfiles/src/branch/main/modules/sway.nix)
-— gets an `initial_session` pointing at that launcher:
-
-```
-boot
- └─ greetd initial_session (autologin as lyrathorpe)
-     └─ gamescope --steam -- steam -tenfoot -pipewire-dmabuf
-         ├─ Steam library / Proton titles
-         ├─ [non-Steam] RetroArch
-         └─ [non-Steam] Clone Hero
-
-quit Steam → greetd default_session → ReGreet → pick Sway (keyboard + mouse)
-```
-
-So there is no greeter at boot and no keyboard needed. Quitting Steam drops back
-to ReGreet, where the ordinary Sway session is available for everything else.
-`services.greetd.restart` defaults to `false` once `initial_session` is set,
-which is what stops a logout looping straight back into autologin.
-
-Two details worth knowing:
-
-- The launcher is referenced as `/run/current-system/sw/bin/steam-gamescope`.
-  The steam module builds that script privately and only adds it to
-  `environment.systemPackages`, so there is no package attribute to point at.
-- `programs.gamescope.capSysNice = true` installs gamescope as a setcap wrapper
-  in `/run/wrappers/bin` instead of the system profile. That path precedes the
-  system profile on `PATH`, so `steam-gamescope` still resolves it.
-
-The greeter is **Dvorak**, like every other host here (`modules/sway.nix` forces
-`XKB_DEFAULT_VARIANT=dvorak` on cage). Only relevant if someone else has to type
-a password.
-
-### Adding RetroArch and Clone Hero to Big Picture
-
-Both are installed system-wide but are not Steam titles. Add each once, from a
-Sway session, via Steam's **Games → Add a Non-Steam Game**; they then appear in
-Big Picture and inherit Steam Input, so the controller works in them without
-further configuration.
-
-## Emulation — RetroArch
-
-`gaming.nix` builds RetroArch through `pkgs.retroarch-bare.wrapper`, which wires
-up the packaged assets, core info and joypad autoconfig profiles. Cores:
-

-| Saturn                                 | `beetle-saturn`          |
-| Dreamcast / NAOMI                      | `flycast`                |
-| PlayStation                            | `beetle-psx-hw`          |
-| PlayStation 2                          | `pcsx2` (LRPS2)          |
-| PSP                                    | `ppsspp`                 |
-| Arcade                                 | `fbneo`, `mame2003-plus` |
-| DOS                                    | `dosbox-pure`            |
-
-A handful of settings are applied on every launch via `--appendconfig`, so they
-are fixed policy rather than saved preferences — changing them in the UI will
-not stick. Everything else stays user-editable as normal.
-
-- `menu_driver = ozone` — the controller-navigable menu.
-- `video_fullscreen = true`.
-- `input_menu_toggle_gamepad_combo = 2` — **L3+R3 opens the RetroArch menu**
-  from inside a running core. Without a pad combo there is no way to exit a game
-  without a keyboard. No retro system emulated here has L3/R3 on its own
-  controller, so the binding cannot collide with a game.
-- `system_directory`, `savefile_directory`, `savestate_directory`,
-  `playlist_directory`, `screenshot_directory`, `thumbnails_directory` and
-  `rgui_browser_directory` — all pointed at the shared library described below,
-  rather than scattered through `~/.config/retroarch`.
-
-An unrecognised key in an appended config is ignored **silently**, so those key
-names are worth keeping in step with upstream if RetroArch is ever bumped
-across a major version.
-
-### BIOS files and expectations
-
-Several cores need BIOS or firmware images that are not redistributable and are
-therefore not packaged. Drop them in `/srv/games/bios`, which is RetroArch's
-system directory on this host:
-
-- **PlayStation 2** (`pcsx2`) — a PS2 BIOS dump. The core will not boot anything
-  without one.
-- **Saturn** (`beetle-saturn`) — region BIOS images.
-- **Dreamcast** (`flycast`) — `dc_boot.bin` / `dc_flash.bin` for most titles.
-- **Nintendo DS** (`melonds`) — optional, but DSi mode and some titles want the
-  real BIOS/firmware.
-
-Be honest about the two heaviest cores. `dolphin` and `pcsx2` are libretro ports
-of emulators whose upstream effort goes into their **standalone** builds; the
-cores lag on compatibility and are the first place to look when a GameCube, Wii
-or PS2 title misbehaves. If a game does not cooperate, add the standalone
-emulators to `environment.systemPackages` in `gaming.nix`:
-
-```nix
-pkgs.dolphin-emu   # GameCube / Wii
-pkgs.pcsx2         # PlayStation 2
-```
-
-Both are controller-driven and can be added to Big Picture the same way as
-RetroArch. The hardware is not the limit here — a GTX 1070 and a Haswell i7 run
-PS2 and Wii comfortably.
-
-Five cores (`snes9x`, `genesis-plus-gx`, `picodrive`, `fbneo`,
-`mame2003-plus`) carry upstream licences with non-commercial or
-no-redistribution-for-profit clauses, so their derivation names are in
-`unfreePackages` in `flake.nix`. Nothing else in the core set needs it.
-
-## Games library layout
-
-Content lives under `/srv/games`, deliberately outside any home directory: it is
-bulky, it is the thing most likely to move to its own disk, and it is shared
-between Steam, RetroArch and Clone Hero rather than owned by one of them.
-Mounting a second drive at `/srv/games` is the only change that move needs.
-
-`gaming.nix` creates the tree with `systemd.tmpfiles.rules` at every boot:
-
-```
-/srv/games/
-├── roms/                 # RetroArch content browser opens here
-│   ├── nes/  snes/  gb/  gbc/  gba/  n64/  nds/  gc/  wii/
-│   ├── mastersystem/  gamegear/  megadrive/  sega32x/  segacd/

-    ├── songs/
-    └── backgrounds/
-```
-
-Directory names under `roms/` follow the libretro/ES-DE convention, so a scraper
-or a second frontend recognises them without anything being renamed.
-
-Everything is `lyrathorpe:users` mode **2775**. The setgid bit matters: the
-owning group is carried onto anything created inside, so a second account — or
-an `rsync` from another machine — does not leave behind files the TV user cannot
-write. The rules create directories if missing and otherwise leave them alone;
-nothing here removes or rewrites content.
-
-RetroArch is pointed at these paths declaratively. The other two have to be told
-once, in their own UIs:
-
-- **Steam** — Settings → Storage → the `+` control → add `/srv/games/steam` as a
-  library folder. Games installed there survive a reinstall of the OS.
-- **Clone Hero** — set the song library path to `/srv/games/clonehero/songs` from
-  its settings screen. Clone Hero keeps its own config in `~/.clonehero`.
-
-## Steam and Proton
-
-`programs.steam.enable` already arranges most of what Proton needs, and it is
-worth recording so it is not re-litigated:
-
-- `hardware.graphics` with `enable32Bit` — the 32-bit GL/Vulkan userspace
-  Proton's 32-bit prefixes link against.
-- Steam's udev rules (`hardware.steam-hardware.enable`) — controller and
-  hidraw access, which is also what lets `dualsensectl` talk to a DualSense.
-- 32-bit PipeWire ALSA (`services.pipewire.alsa.support32Bit`), derived from
-  `alsa.enable`, which `gaming.nix` turns on for the older native titles that
-  talk to ALSA directly rather than through the Pulse shim.
-- Wine's fonts — Liberation, DejaVu, FreeFont and the Noto set arrive with
-  `fonts.enableDefaultPackages` plus `modules/common-nixos.nix`. Liberation is
-  metric-compatible with the Microsoft core fonts, so text lays out correctly
-  without shipping unfree `corefonts`.
-- `vm.max_map_count` is **1048576** in the nixpkgs default sysctls, above what
-  DX12 and Unreal titles need. No override required — this is the one people
-  usually copy from Arch wiki posts and it is already handled.
-
-What is **not** covered by default, and is set explicitly in `gaming.nix`:
-
-- `systemd.settings.Manager.DefaultLimitNOFILE = "1024:1048576"`. esync opens
-  one eventfd per Wine synchronisation object and runs out against systemd's
-  default 524288 hard limit in the heaviest titles. Only the hard limit is
-  raised; the soft limit stays at 1024, because lifting that breaks
-  `select()`-based programs elsewhere on the system.
-- `extraCompatPackages = [ pkgs.proton-ge-bin ]`. The module puts its
-  `steamcompattool` output on `STEAM_EXTRA_COMPAT_TOOLS_PATHS`, which is what
-  makes **GE-Proton** appear in the client's compatibility list.
-- `protontricks.enable` — winetricks against a Proton prefix, the standard
-  repair when a title needs a runtime (dotnet, vcrun, Media Foundation) Proton
-  does not ship.
-- `programs.gamemode.enable` — applies the performance CPU governor around games
-  that request it.
-
-One thing is **not declarative**: Steam Play must be switched on in the client,
-once, per account — **Settings → Compatibility → Enable Steam Play for all other
-titles**. Nix cannot set this; it lives in Steam's own config.
-
-Verify the Proton side after installing:
-
-```sh
-vulkaninfo --summary            # 64-bit ICD
-nvidia-smi                      # driver up
-ulimit -Hn                      # expect 1048576
-# in a game's launch options, to confirm esync/fsync are active:
-#   PROTON_LOG=1 %command%     → ~/steam-<appid>.log
-```
-
-## Controllers
-
-- **Xbox One / Series over Bluetooth** — `hardware.xpadneo.enable`. The
-  out-of-tree driver; the in-kernel `xpad` handles these badly over Bluetooth
-  (wrong button mapping, no rumble). The module enables bluez itself.
-- **Xbox 360, wired** — in-kernel `xpad`, autoloaded by udev on plug-in.
-  Nothing to configure. The kernel is built with `CONFIG_JOYSTICK_XPAD=m`,
-  `CONFIG_JOYSTICK_XPAD_FF=y` (rumble) and `CONFIG_JOYSTICK_XPAD_LEDS=y`. The
-  360 wireless PC receiver uses the same driver and works the same way.
-- **DualSense / DualShock 4** — in-kernel `hid-playstation`, over both USB and
-  Bluetooth. No driver config. `dualsensectl` is installed for LED, battery and
-  microphone control; it works because Steam's udev rules grant hidraw access.
-- **Clone Hero guitars** — plain USB HID gamepads, handled in-kernel. Nothing to
-  configure.
-
-`hardware.bluetooth.powerOnBoot` is set so the adapter is up before the Steam
-session starts and a pad can reconnect unattended.
-`settings.General.Experimental = true` is what enables battery level reporting
-for Bluetooth gamepads — it is still behind bluez's experimental flag.
-
-Pair a new controller from Big Picture (**Settings → Controller**), or from a
-Sway session with `bluetoothctl`. If a pad connects but no input arrives, check
-`journalctl -b -u bluetooth` and confirm `hid_xpadneo` is loaded
-(`lsmod | grep xpadneo`).
-
-The Xbox One / Series USB **wireless dongle** is deliberately not configured. It
-needs `hardware.xone.enable`, which **blacklists `xpad`** — that would break the
-wired 360 pads — as well as `mt76x2u`, and pulls in proprietary dongle firmware.
-Not worth the side effects unless that dongle is actually in use, and if it ever
-is, the 360 pads have to be re-tested.
-
-## Untested claims
-
-This host has not been built or booted yet. Two things are worth watching on
-first boot:
-
-- **gamescope on the proprietary NVIDIA driver.** `gaming.nix` sets
-  `GBM_BACKEND=nvidia-drm` and `__GLX_VENDOR_LIBRARY_NAME=nvidia` for the
-  session, which is the standard fix, but the combination has a history of
-  needing tweaks. If the session dies at startup, switch the greeter back to
-  interactive by commenting out `services.greetd.settings.initial_session`, log
-  into Sway, and read `journalctl --user -b`.
-- **Television resolution and refresh.** gamescope takes the output's native
-  mode by default. Add `gamescopeSession.args = [ "-W" "3840" "-H" "2160" "-r"
-"60" ]` if a specific mode is wanted.
-
-There is no HDMI-CEC configuration here, so the TV remote will not drive the
-box; that needs a Pulse-Eight adapter or a working CEC bridge on the board.
-Nothing boots to a splash screen either — Plymouth was left out deliberately, as
-early KMS with the proprietary driver makes it unreliable.
-
-## Networking
-
-Wired NetworkManager from `../../modules/desktop.nix`; `modules/ssh.nix` adds
-key-only sshd, which is the practical way to administer a machine with no
-keyboard attached. The firewall is default-deny (`modules/workstation.nix`);
-Steam Remote Play and local network game transfers open their own ports through
-`programs.steam`.

-# Mac Pro 3,1 (Early 2008) — install notes
-
-Flake host: `lyrathorpe-macpro31`. Desktop (`portable = false`, imports
-`../../modules/desktop.nix`). Files: `configuration.nix`, `nvidia.nix`,
-`hardware-configuration.nix`.
-
-## Hardware configuration
-
-`hardware-configuration.nix` here is the real config generated by
-`nixos-generate-config` on the machine. Root is an **LVM** logical volume
-(`/dev/mapper/MacPro-Root`, ext4); the ESP (vfat) and swap are referenced by
-UUID. The initrd carries `dm-snapshot` for the LVM root. Regenerate and commit
-if the disk layout changes.
-
-## Bootloader
-
-The Mac Pro 3,1 has **64-bit EFI**, so it uses **systemd-boot** (no GRUB/CSM
-shim). `canTouchEfiVariables = false` because Apple's firmware does not reliably
-accept `efibootmgr` NVRAM writes.
-
-Apple-EFI quirk: if the firmware boot picker does not show NixOS after install,
-either
-
-- uncomment `boot.loader.efi.efiInstallAsRemovable = true;` in

-## Graphics — NVIDIA Quadro P400
-
-The stock card (**ATI Radeon HD 2600 XT** or **NVIDIA GeForce 8800 GT**,
-depending on the unit) has been replaced with an **NVIDIA Quadro P400** (Pascal,
-GP108). Everything driver-related lives in [`nvidia.nix`](https://code.emmathe.dev/lyrathorpe/nixfiles/src/branch/main/hosts/MacPro31/nvidia.nix):
-
-- **Driver branch 580** (`nvidiaPackages.legacy_580`), _not_ the nixpkgs default
-  (`production`, currently 595.x). 580 is the last branch that supports
-  Maxwell/Pascal/Volta and is maintained as an LTS branch until Aug 2028; a
-  newer branch does not drive this card at all.
-- `modesetting.enable = true` — mandatory for Wayland (sets
-  `nvidia-drm.modeset=1`); without it wlroots gets no GBM device and both Sway
-  and the greeter fail to start.
-- `open = false` — the open kernel modules require Turing or later.
-- Sway runs with `--unsupported-gpu` (`programs.sway.extraOptions`); wlroots
-  refuses the proprietary driver otherwise. `cage`/ReGreet needs no such flag.
-- nouveau and `nvidiafb` are blacklisted automatically by the NVIDIA module.
-
-The driver is unfree, so it is **not in the binary cache**: the kernel module is
-compiled on the machine, which on these 2008 Xeons is slow — budget for a long
-first rebuild and again after every kernel bump. The package names are
-allowlisted in `unfreePackages` in [`flake.nix`](https://code.emmathe.dev/lyrathorpe/nixfiles/src/branch/main/flake.nix).
-
-Note the Mac Pro shows no EFI boot screen with a stock PC card (no Apple EFI
-ROM): the machine boots blind until KMS brings the display up. That is expected,
-not a fault.
-
-Verify after a rebuild:
-
-```sh
-nvidia-smi
-```
-
-## Docker with CUDA
-
-`nvidia.nix` also enables Docker and gives containers GPU access via **CDI**
-(`hardware.nvidia-container-toolkit.enable`), which generates device specs from
-the host driver at boot (regenerated by a udev rule when the `nvidia` device
-appears) and turns on the daemon's CDI feature:
-
-```sh
-docker run --rm --device=nvidia.com/gpu=all nvidia/cuda:12.9.1-base-ubuntu24.04 nvidia-smi
-```
-
-- Use the `--device=nvidia.com/gpu=all` form. `--gpus all` is the legacy
-  runtime-wrapper path (`virtualisation.docker.enableNvidia`), which is
-  deprecated upstream and deliberately not enabled here.
-- **CUDA version matters.** The P400 is compute capability 6.1 (`sm_61`); CUDA
-  13 dropped Maxwell/Pascal/Volta, so container images must ship a **CUDA 12.x
-  or older** runtime. The 580 driver itself is happy with either.
-- 2 GB of VRAM, 256 CUDA cores — fine for encode/decode and small models, not
-  for training anything serious.
-- Docker socket is local-only (no TCP listener, unlike the Pi). Users need the
-  `docker` group; the registry already grants it.
-
-### "Driver Not Loaded" from the CDI generator
-
-`nvidia-container-toolkit-cdi-generator.service` fails with
-`failed to initialize NVML: Driver Not Loaded` whenever the `nvidia` kernel
-module is not loaded in the **running** kernel. After a kernel bump that is
-unavoidable — the rebuilt module cannot load until reboot — so the unit is
-guarded with `ConditionPathExists=/proc/driver/nvidia/version` and skips
-instead of failing. Without that guard it also takes `docker.service`
-(`requiredBy`) with it and makes `nixos-rebuild switch` exit non-zero.
-
-**Reboot after a rebuild that touches the driver or the kernel.** The toolkit's
-udev rule restarts the generator when the GPU device appears, so the CDI specs
-are written on the next boot. To check the state:
-
-```sh
-lsmod | grep nvidia            # nvidia, nvidia_modeset, nvidia_drm, nvidia_uvm
-cat /proc/driver/nvidia/version
-nvidia-smi
-systemctl status nvidia-container-toolkit-cdi-generator.service
-ls /var/run/cdi                # the generated spec
-```
-
-If the module is genuinely absent after a reboot, check `dmesg | grep -i
-nvidia` (build/version mismatch, or nouveau still bound — the module blacklists
-it, so that should not happen).

-## Claude Code — not installed here
-
-The dual Harpertown Xeons are **x86-64-v1** (SSE4.1, but no SSE4.2/POPCNT) and
-the Node runtime Claude Code ships on requires x86-64-v2. `configuration.nix`
-declares `features.cpu.microarchLevel = 1`, which switches the tool off through
-the fleet-wide gate in [`../../modules/features.nix`](https://code.emmathe.dev/lyrathorpe/nixfiles/src/branch/main/modules/features.nix)
-— see the root README. Forcing `features.claudeCode.enable` on here is an
-evaluation error, not a broken install.
-
-## Networking
-
-Wired Ethernet via NetworkManager (from `desktop.nix`) — the Mac Pro has two
-gigabit ports.
-
-## Login
-
-Graphical login via a Wayland greeter — `greetd` running ReGreet inside the
-`cage` kiosk compositor — configured centrally in `../../modules/sway.nix` for
-every Sway host (gated on `features.swayDesktop.enable`). The greeter is forced
-to the Dvorak layout to match the console and Sway session. Set the user
-password (`passwd lyrathorpe`) after install, or the greeter cannot
-authenticate. Requires working KMS (NVIDIA modesetting — see Graphics).

-
-**Theming:** `fzf`, `bat`, `btop`, `lazygit` and `git`'s `delta` pager are all
-Catppuccin Mocha, driven from the shared `../lib/catppuccin-mocha.nix` palette / the
-catppuccin upstream themes.
-
-**Env & defaults:** `xdg.enable` on; `PAGER`/`MANPAGER` (bat) set in `default.nix`
-(the editor owns `$EDITOR`/`$VISUAL`); `xdg.mimeApps` maps web→Firefox,
-directories→nemo (`desktop.nix`).
-
-## Replacing the classics
-
-Muscle memory is the expensive part of this, not the packages. Four commands are
-**shadowed** — the old name now runs a new tool. Everything else keeps a new
-name, so the original is never displaced.
-
-### Shadowed by an alias
-
-| You type | You now run          | The original is still `command <name>` / `\<name>` |
-| -------- | -------------------- | -------------------------------------------------- |
-| `cat`    | `bat --paging=never` | `command cat`                                      |
-| `du`     | `dust`               | `command du`                                       |
-| `df`     | `dysk`               | `command df`                                       |
-| `ps`     | `procs`              | `command ps`                                       |
-
-Only read-only commands are shadowed, so the worst case of a wrong flag is a
-retype rather than lost data. `rm`, `grep`, `curl` and `find` are deliberately
-left alone — see "Left alone on purpose" below.
-
-**Where the aliases apply.** They are written into `~/.config/zsh/.zshrc`, so
-they exist only in an **interactive zsh**:
-
-- shell scripts, `Makefile` recipes and anything another program `exec`s get the
-  real coreutils binary — nothing that parses output can break;
-- `sudo du -sh /var` runs the real `du`: zsh does not expand an alias after
-  `sudo`;
-- `KUBECONFIG=… kubectl …` **does** expand — zsh expands aliases after a
-  variable-assignment prefix. That is what makes the kubecolor alias on the work
-  box (below) useful rather than a special case you have to remember.
-
-### Flag gotchas
-
-These replacements are not drop-in. The two marked **silent** are the dangerous
-ones — they succeed and answer a different question than the one you asked.
-Everything else fails loudly.
-
-| Old habit           | What happens now                                                                                                      | Do this instead                                                     |
-| ------------------- | --------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------- |
-| `du -sh dir`        | dust prints its usage and exits non-zero — `-h` is not a dust flag                                                    | `dust dir` (units are human by default; the total is the last row)  |
-| `du -s dir`         | **silent**: dust's `-s` is `--apparent-size`, not `--summarize`                                                       | `dust -d 0 dir` for a single total line                             |

-| `df -a`             | works, same meaning (all mount points)                                                                                | —                                                                   |
-| `df /some/path`     | works, same meaning (the device holding that path)                                                                    | —                                                                   |
-| `ps aux`            | **silent**: `aux` is read as a search keyword, so you get only processes whose command line contains the string "aux" | `procs` lists everything; `procs <pattern>` filters                 |
-| `ps -ef`            | `error: unexpected argument '-e'`                                                                                     | `procs`                                                             |
-| `ps -p 1234`        | not recognised                                                                                                        | `procs 1234`                                                        |
-| `procs -a`          | **silent**: `-a` is `--and` (combine search keywords), not "all"                                                      | drop it — `procs` already shows everything                          |
-| `cat -v` / `cat -e` | `error: unexpected argument`                                                                                          | `cat -A` does work (bat implements show-all); else `command cat -v` |
-| `cat -n`            | works, but bat's number column, not coreutils' layout                                                                 | fine to read; `command cat -n` when the exact layout matters        |
-| `cat <binary>`      | prints `<BINARY>` to a terminal instead of dumping the bytes                                                          | `hexyl <file>`, or `command cat` to dump                            |
-
-Useful new capabilities in the same tools: `procs --tree`, `procs --watch`,
-`dust -r` (largest at the top), `dysk -s size`, `dysk -f 'type=ext4'`.
-
-**Piping is safe for `cat`.** bat drops all decoration and colour when stdout is
-not a terminal, so `cat f | sha256sum` is byte-for-byte what coreutils `cat`
-would have given. The others are TUI-shaped tables with no stable format — if
-something needs to parse them, use `dysk --json`/`--csv`, `procs --json`, or the
-original binary.
-
-### Renamed, not shadowed
-
-| Instead of                  | Use     | Notes                                                                                                                                                                                                |
-| --------------------------- | ------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
-| `rm`                        | `trash` | Moves to the XDG trash. `trash-list`, `trash-restore` (interactive picker), `trash-empty [days]`. It never deletes in place: if it cannot create a trash directory on that filesystem it errors out. |
-| `dig` / `nslookup`          | `doggo` | `doggo example.com MX @1.1.1.1`; `--json` for scripting. Not aliased — `dig` (from the `bind` closure that other modules pull in) stays where scripts expect it.                                     |
-| `curl` (interactive poking) | `xh`    | HTTPie syntax: `xh POST api.example/x name=lyra`. `xhs` is `xh --https`. **curl stays installed and unaliased** — it is what scripts and CI use.                                                     |
-| `tar` / `unzip` / `7z`      | `ouch`  | `ouch d file.<anything>`, `ouch c out.tar.zst src/`, `ouch l archive`. Format is inferred from the extension. The oh-my-zsh `extract` function still works too.                                      |
-| `jq` (exploring a payload)  | `jnv`   | Interactive filter builder over a JSON file; it prints the jq expression you built. `jq` remains the scripting tool.                                                                                 |
-| `hexdump -C` / `xxd`        | `hexyl` | `hexyl -n 256 -s 0x40 file` for a window into a large file.                                                                                                                                          |
-| `strings` on a known format | `fq`    | jq syntax over binary formats: `fq -d elf '.sections[].name' ./bin`.                                                                                                                                 |
-| skimming a man page         | `tldr`  | Worked examples. `man` is untouched (and still rendered through bat).                                                                                                                                |
-
-### Left alone on purpose
-
-- **`grep`** is not aliased to `rg`. ripgrep is recursive by default, skips
-  gitignored and hidden files, and uses a different regex dialect (no
-  backreferences, no POSIX classes in the same form). A `grep` habit silently
-  producing fewer matches is a worse failure than typing three characters. Type
-  `rg`.
-- **`rm`** is not aliased to `trash-put`. Retraining `rm` to mean "recoverable"
-  is a habit that follows you onto every machine where it is not — remote hosts,
-  root shells, containers, CI. Type `trash`.
-- **`find`** is not aliased to `fd`; the `-exec`/`-print0` vocabulary has no
-  equivalent and scripts lean on it. Type `fd`.
-- **`sed`** is not aliased to `sd`; `sd` takes real regex and literal
-  replacements, not sed's expression language. Type `sd`.
-- **coreutils itself** is not swapped for `uutils-coreutils`. It is packaged and
-  tempting, but every Nix builder and shell script on these hosts is written
-  against GNU behaviour, including its forty-year-old edge cases.
-
-### Work box only: kubectl → kubecolor
-
-On EDaaS (`work.nix`) `kubectl` is aliased to **kubecolor**, which runs the real
-kubectl underneath and colourises what comes back. Nothing to relearn: every
-flag, subcommand and plugin passes straight through, unrecognised output is
-printed verbatim, and colour is dropped automatically when stdout is not a
-terminal — so `kubectl get -o json … | jq` is unchanged. The alias also applies
-to `KUBECONFIG=prodconfig kubectl …`, per the alias-expansion note above.
-Completions are kubectl's own (`compdef kubecolor=kubectl`). Escape hatch as
-ever: `command kubectl`.
-
-### sudo → sudo-rs
-
-Every NixOS host now uses **sudo-rs**, the memory-safe reimplementation, in
-place of `sudo` (`modules/common-nixos.nix`; the macOS host keeps Apple's sudo
-with Touch ID). Day to day there is nothing to learn — `sudo`, `sudo -i`,
-`sudo -u`, `sudo -l`, `sudoedit` and `visudo` all behave as before against this
-fleet's stock "wheel, with a password" policy. What it does **not** implement:
-host aliases, LDAP/SSSD sudoers, `sudoreplay`, and most `Defaults` settings.
-Needing any of those means reverting to `security.sudo`.
-
-One exception to the password: the EDaaS box sets
-`security.sudo-rs.wheelNeedsPassword = false`. NixOS-WSL ships that default for
-`security.sudo` — WSL has no console login, so the trust boundary is the Windows
-session and the Linux account password is never one the user chose — and the
-option does not carry across to the `security.sudo-rs` module, which defaults to
-requiring one. Without the explicit setting, `sudo` on that host prompts for a
-password nobody knows.
-
-If a host ever refuses to escalate, get a root shell that does not go through
-sudo (`wsl -u root -d NixOS` on the work box; the console or a serial/HDMI login
-elsewhere) and roll back with `nixos-rebuild switch --rollback`, or pick the
-previous generation from the boot menu.
-
-## tmux
-
-**Auto-start:** opening any interactive terminal — foot, iTerm2, the WSL shell, the
-Linux console — drops you straight into a tmux session named `main` (attach if it
-exists, else create). Panes run a plain non-login zsh. It deliberately does **not**
-fire for SSH sessions, VS Code's integrated terminal, already-inside-tmux, or
-non-interactive shells. Escape hatch: `NO_TMUX=1 <terminal>` opens a bare shell.

-the prompt), `catppuccin` (Mocha statusline), `resurrect` + `continuum`
-(sessions auto-save and restore across reboots). The statusline draws Nerd-Font
-glyphs — see Fonts.
-
-## Fonts
-
-**JetBrainsMono Nerd Font**, **Noto Sans** and **Noto Color Emoji** are
-installed on every host (in `common-nixos.nix`, because tmux/terminals run
-everywhere; the Mac installs the Nerd Font to `/Library/Fonts` via the Darwin
-config). `fonts.fontconfig.defaultFonts` maps the generic families so anything
-asking for `monospace` gets the Nerd Font (with emoji fallback) — this also
-gives the WSL box emoji/sans coverage it otherwise lacked. foot uses the Nerd
-Font as its main font automatically. iTerm2's font is a GUI setting — set it to
-_JetBrainsMono Nerd Font_ (Settings → Profiles → Text → Font) so the tmux
-statusline glyphs render instead of `?`.
-
-## Editor (Neovim)
-
-`nvim` — aliased to `vi`/`vim`, and set as `$EDITOR`/`$VISUAL` — is configured
-declaratively with **nixvim**, so the same plugins and config are baked in on
-every host. Migrated from plain vim; the practical gain is a real LSP stack in
-place of the old (inert) ALE.

-Leader is `Space`. LSP keymaps (`gd`, `gr`, `K`, `<leader>rn`, `<leader>ca`) and
-the file-tree toggle are listed in
-[`keybindings.md`](./keybindings.md#neovim). Add a universal language server by
-enabling it under `programs.nixvim.plugins.lsp.servers` in `editor.nix`;
-host-specific ones go in that host's module — the work box (`work.nix`) adds
-`omnisharp` (C#) and `helm_ls` (Helm), kept off the personal machines.
-
-## git
-
-Pager is **delta**. **commitizen** is installed on every host; `cz` defaults to
-Conventional Commits. **lazygit** (themed) is the TUI. The commit-graph is kept
-current (`gc`/`fetch.writeCommitGraph`) so `lg` stays fast.
-

-| `cz` `cc`                | `git cz <sub>` (e.g. `git cz c`) and `git cc` → commitizen prompt         |
-| `dft`                    | structural (syntax-aware) diff via difftastic; takes `git diff` arguments |
-
-**`git dft` vs `git diff`.** delta stays the default renderer for everything;
-`diff.external` is deliberately **not** set, so `git diff`, `git show` and
-anything parsing their output are unchanged. Reach for `dft` when a refactor
-moved code around and a line-based diff is noise. One wrinkle: `dft` is a
-`!`-shell alias, and git runs those from the repository root — pass pathspecs
-relative to the root, not to your current directory.

-The **work box keeps its own `~/.ssh/config`** (home-manager's `programs.ssh` is

-
-## Claude Code
-
-Managed declaratively by [`claude.nix`](https://code.emmathe.dev/lyrathorpe/nixfiles/src/branch/main/home/claude.nix) on every host whose CPU
-can run it (the CLI is `pkgs.claude-code`, tracked to unstable via the flake
-overlay).
-
-**Capability gate.** The module installs nothing — CLI or files — when
-`osConfig.features.claudeCode.enable` is off. That flag is derived fleet-wide
-from the host's declared CPU level (see "CPU capability gating" in the root
-README): the Node runtime needs SSE4.2/POPCNT, so anything below x86-64-v2 (the
-Mac Pro 3,1) is excluded. Hosts that do not define the option — the Darwin host
-and the standalone `homeConfigurations` — keep it enabled.
-
-| Managed (static, from Nix)                          | Left mutable (runtime state)                           |
-| --------------------------------------------------- | ------------------------------------------------------ |
-| `~/.claude/CLAUDE.md` (persona + memory workflow)   | `settings.json` (permissions, model, theme, `/config`) |
-| `~/.claude/output-styles/soviet-engineer.md`        | `.credentials.json`, history, caches                   |
-| `~/.claude/memory/` (read-only symlink to the repo) |                                                        |
-
-`settings.json` is intentionally **not** managed: Claude rewrites it at runtime
-(interactive permission grants, `/config`), which a read-only store symlink would
-break.
-
-**Memory is sourced from this repo.** The files in
-[`claude/memory/`](https://code.emmathe.dev/lyrathorpe/nixfiles/src/branch/main/home/claude/memory) are the source of truth; they are symlinked
-read-only into `~/.claude/memory`, so recall works but the runtime "save a
-memory" path does not. To add/change/remove a memory, edit `claude/memory/`
-(one file per memory + the `MEMORY.md` index) and rebuild — `CLAUDE.md` tells
-Claude to route new memories there.
-
-## Maintenance behaviours
-
-- **zcompdump reset** — `~/.config/zsh/.zcompdump*` (plus legacy `~/.zcompdump*`
-  and the cache copy) is removed on every activation, so a stale
-  dump (pointing at `/nix/store` paths a rebuild or a manual GC removed) can't
-  break completion with `_git: function definition file not found`.
-- **GC** — no scheduled timer; collect garbage deliberately (`nh clean all` /
-  `nix-collect-garbage -d`) when no important session is running.

+
+**Theming:** `fzf`, `bat`, `btop`, `lazygit` and `git`'s `delta` pager are all
+Catppuccin Mocha, driven from the shared `../lib/catppuccin-mocha.nix` palette / the
+catppuccin upstream themes.
+
+**Env & defaults:** `xdg.enable` on; `PAGER`/`MANPAGER` (bat) set in `default.nix`
+(the editor owns `$EDITOR`/`$VISUAL`); `xdg.mimeApps` maps web→Firefox,
+directories→nemo (`desktop.nix`).
+
+## tmux
+
+**Auto-start:** opening any interactive terminal — foot, iTerm2, the WSL shell, the
+Linux console — drops you straight into a tmux session named `main` (attach if it
+exists, else create). Panes run a plain non-login zsh. It deliberately does **not**
+fire for SSH sessions, VS Code's integrated terminal, already-inside-tmux, or
+non-interactive shells. Escape hatch: `NO_TMUX=1 <terminal>` opens a bare shell.

+(sessions auto-save and restore across reboots). The statusline draws Nerd-Font
+glyphs — see Fonts.
+
+## Fonts
+
+**JetBrainsMono Nerd Font**, **Noto Sans** and **Noto Color Emoji** are
+installed on every host (in `common-nixos.nix`, because tmux/terminals run
+everywhere; the Mac installs the Nerd Font to `/Library/Fonts` via the Darwin
+config). `fonts.fontconfig.defaultFonts` maps the generic families so anything
+asking for `monospace` gets the Nerd Font (with emoji fallback) — this also
+gives the WSL box emoji/sans coverage it otherwise lacked. foot uses the Nerd
+Font as its main font automatically. iTerm2's font is a GUI setting — set it to
+_JetBrainsMono Nerd Font_ (Settings → Profiles → Text → Font) so the tmux
+statusline glyphs render instead of `?`.
+
+## Editor (Neovim)
+
+`nvim` — aliased to `vi`/`vim`, and set as `$EDITOR`/`$VISUAL` — is configured
+declaratively with **nixvim**, so the same plugins and config are baked in on
+every host. Migrated from plain vim; the practical gain is a real LSP stack in
+place of the old (inert) ALE.

+Leader is `Space`. LSP keymaps (`gd`, `gr`, `K`, `<leader>rn`, `<leader>ca`) and
+the file-tree toggle are listed in
+[`KEYBINDINGS.md`](./KEYBINDINGS.md#neovim). Add a universal language server by
+enabling it under `programs.nixvim.plugins.lsp.servers` in `editor.nix`;
+host-specific ones go in that host's module — the work box (`work.nix`) adds
+`omnisharp` (C#) and `helm_ls` (Helm), kept off the personal machines.
+
+## git
+
+Pager is **delta**. **commitizen** is installed on every host; `cz` defaults to
+Conventional Commits. **lazygit** (themed) is the TUI. The commit-graph is kept
+current (`gc`/`fetch.writeCommitGraph`) so `lg` stays fast.

+
+The **work box keeps its own `~/.ssh/config`** (home-manager's `programs.ssh` is
+forced off there) but still runs the agent.
+
+## Claude Code
+
+Managed declaratively by [`claude.nix`](./claude.nix) on every host (the CLI is
+`pkgs.claude-code`, tracked to unstable via the flake overlay).
+
+| Managed (static, from Nix)                          | Left mutable (runtime state)                           |
+| --------------------------------------------------- | ------------------------------------------------------ |
+| `~/.claude/CLAUDE.md` (persona + memory workflow)   | `settings.json` (permissions, model, theme, `/config`) |
+| `~/.claude/output-styles/soviet-engineer.md`        | `.credentials.json`, history, caches                   |
+| `~/.claude/memory/` (read-only symlink to the repo) |                                                        |
+
+`settings.json` is intentionally **not** managed: Claude rewrites it at runtime
+(interactive permission grants, `/config`), which a read-only store symlink would
+break.
+
+**Memory is sourced from this repo.** The files in
+[`claude/memory/`](./claude/memory) are the source of truth; they are symlinked
+read-only into `~/.claude/memory`, so recall works but the runtime "save a
+memory" path does not. To add/change/remove a memory, edit `claude/memory/`
+(one file per memory + the `MEMORY.md` index) and rebuild — `CLAUDE.md` tells
+Claude to route new memories there.
+
+## Maintenance behaviours
+
+- **zcompdump reset** — `~/.config/zsh/.zcompdump*` (plus legacy `~/.zcompdump*`
+  and the cache copy) is removed on every activation, so a stale
+  dump (pointing at `/nix/store` paths a rebuild or a manual GC removed) can't
+  break completion with `_git: function definition file not found`.
+- **GC** — no scheduled timer; collect garbage deliberately (`nh clean all` /
+  `nix-collect-garbage -d`) when no important session is running.
+
+## Per-host differences

-Recurring PR-review feedback from human reviewers (Tom Wilkins, Andrew Hyde, Gilberto Pestanarosa) on the `multicluster` and `unified-helm` repos, on how to write comments in code and IaC:
-
-- **No Jira/WSP ticket IDs in code comments or WAF `msg:` strings by default.** Add a ticket ref only when there is a specific reason to. Never duplicate the id, and never put a ticket URL in a comment. Tracking/rationale belongs in the PR description and the Jira ticket, not in `.tf`, `.tftpl`, or `.yaml`. (Flagged repeatedly — PRs #1735, #1762.)
-- **Comment the non-obvious "why", not the obvious "what".** Drop comments that restate what the code or file plainly does (e.g. a header on `namespace.yaml` re-announcing that it defines a namespace). If a reviewer can't tell why a comment exists, it shouldn't.
-- **Keep it short and readable.** No multi-line block where one line does; if a comment isn't clear after a couple of reads, rewrite it plainer. Prefer trimming to the single load-bearing sentence over hedged prose. (PRs #1745, #216.)
-- **In Helm charts, use `#` YAML comments — not `{{/* */}}` — for anything that must appear in the rendered manifest.** Helm template comments are stripped before render, so port/label explanations meant for the live chart have to be `#`. (PR #216.)
-
-**Why:** Multiple human reviewers, across multiple PRs, consistently push back on verbose comments and gratuitous ticket references. Terse, purpose-driven comments clear review faster.
-
-**How to apply:** When writing or editing comments in code/IaC, default to: no ticket id, one line, non-obvious "why" only. This supersedes the "one-liner + WSP ticket reference" phrasing that used to live in [[workflow-review-and-comments]]. Relates to [[docs_keep_updated]].

-The Copilot reviewer on the `multicluster` / `unified-helm` repos raises blocking-sounding "this will fail" claims that are sometimes wrong. Verify against the language spec and the live/`master` config before treating one as real or applying its fix.
-
-Recorded false positives (both Terraform, both Emma-flagged "for future reference"):
-
-- **PR #1742** — claimed `var.map.hyphenated-key` dot access is parsed as subtraction and breaks `terraform plan`. False: HCL2 identifiers may contain hyphens (`ID_Start (ID_Continue | "-")*`), and the same pattern is already live on `master` in prod. Bracket indexing was adopted anyway as marginally clearer, not as a fix.
-- **PR #1745** — claimed the `aks_pools` per-pool `max_surge` lookup was off-by-one and should use `count.index + 1`. False: every config attribute on that resource indexes with `count.index`; only the cosmetic `name`/`az_nodepool` label uses `+1`. Applying `+1` would have introduced a real bug (wrong pool, and out-of-bounds on the last pool).

-**Why:** Blindly applying a plausible-but-wrong Copilot suggestion can introduce a real defect or waste review cycles.
-
-**How to apply:** For any Copilot claim that code is broken or unsafe, confirm it against the relevant spec and the existing working config first; if it's wrong, say so plainly on the PR and leave the code. Genuine Copilot catches (over-broad WAF `@beginsWith`, missing input validation, doc/behaviour drift) still get fixed. Relates to [[workflow-review-and-comments]] and [[code_comment_style]].

-`az ad group member list --group <id>` and `GET /groups/{id}/members` both return an **empty collection**, with no error, for a group whose only members are service principals — at least when called with Lyra's user account. The read looks authoritative and is not.

-```sh
-# members, cast to the type that is being hidden

-
-**How to apply:** any group that deployment or automation identities belong to — `*-cluster-admins`, `*-keyvault`, anything created by `rg-prereqs` — must be checked with one of the above before concluding it is empty. Cross-check against Terraform: a plan reporting "No changes" against a `members` attribute is strong evidence the membership is present, and outranks the `az` read. On 2026-08-28 the plain read produced a Bug (WSP-33432, cancelled) claiming five `*-cluster-admins` groups across three tenants had been emptied; all five held their deployment principals the whole time.

-**Verifying — the recurring trap:** `git log --show-signature` and the `%G?` format both report `N` and print `error: gpg.ssh.allowedSignersFile needs to be configured and exist for ssh signature verification`. This does NOT mean the commit is unsigned — it means git has no local allowed-signers file to check it against. The signature is present. Confirm the real state with `git cat-file commit <ref> | grep -i '^gpgsig'`: an `-----BEGIN SSH SIGNATURE-----` block means signed. So `N` here is cosmetic, not a signing failure — do not "fix" it by re-committing. To make local verification actually pass, set `gpg.ssh.allowedSignersFile` to a file mapping the signer to the pubkey (a line like `emma.thorpe@cloud.com ssh-ed25519 AAAA...`); Gitea/CI verifies server-side regardless.

+**Commit messages:** Conventional Commits. Subject line: `<type>(<TICKET-ID>): <imperative summary>` — ticket ID as the scope. Use additional `-m` flags for rationale/body. Commit at logical checkpoints, not one giant final commit.
 
-**`<TICKET-ID>` is the real ticket for the work in hand.** It is a symbol to substitute, never a literal — if a commit subject ever reaches git still containing `<TICKET-ID>`, or a made-up number, that is a defect. Establish the actual ID before the first commit, in this order:
+**Why:** Lyra's standard workflow for traceability and clean history.
 
-1. The ticket Lyra named in the request.
-2. The current branch name — `task/WSP-32542/remove-wspgov-terraform` gives `WSP-32542`. Extract it: `git branch --show-current | grep -oE '[A-Z]{2,}-[0-9]+'`.
-3. The ticket the branch's existing commits already use.
-
-If none of those yield an ID, ask which ticket to file the work under. Do not guess, do not reuse the ID from an unrelated earlier task in the session, and do not invent a plausible-looking number. Every commit in a branch normally carries the same ID; if the work genuinely spans two tickets, split the commits accordingly rather than picking one at random.
-
-**Exception — repos with no issue tracker.** Personal repos such as `nixfiles` have no Jira project. There the scope is the area of the change, not a ticket: `chore(claude): ...`, `chore(deps): ...`, `feat(hosts): ...`. Conventional form is still required; only the ticket scope is dropped. Never invent a WSP number to satisfy the rule in a repo that has no tickets. The ticket requirement applies to the work repos under `~/code` that are backed by the WSP Jira project and gated by CI.
-
-**This format is mandatory and overrides the repo's existing log style.** Many repos (`multicluster`, `core-services-cloud`) have histories full of bare `<TICKET-ID>: summary` subjects written by other people. Do not copy that. Match repo style for _branch names_ only; commit subjects are always full Conventional Commits with the ticket scope. CI enforces this, and a failure means Lyra rebases the history by hand.
-
-**Known failure mode — scope decay across a session.** The first commit gets `fix(<TICKET-ID>): ...` correctly, then follow-up commits in the same sitting degrade to bare `test: add tests for class`, `refactor: hoist middleware`, `chore: tidy`. This has caused real rebase work in `core-services-cloud`. The second, third and fifth commits need the ticket scope exactly as much as the first. Re-read the subject against the format before every single `git commit`.
-
-**Merge commits count too.** Prefer `git rebase origin/<base>` over `git merge` so none is created. If unavoidable, set the message explicitly: `git merge --no-ff -m "<TICKET-ID>: merge master into <branch>"`. Keep the ID uppercase; the check is case-sensitive.
-
-**Before pushing, verify — do not skip this:**
-
-```
-git log --format=%s origin/<base>..HEAD | grep -vE '^[a-z]+(\([A-Z]{2,}-[0-9]+\))!?: '
-```
-
-Must print nothing. Writing each subject carefully is not a substitute for running it.
-
-**Auditing past behaviour is unreliable.** If Lyra has already rebased to fix a bad subject, the log shows her corrected version, not what was originally written. A clean `git log` is not evidence that nothing was wrong. Check author date vs committer date (`--format="%ad %cd"`) — a mismatch means history was rewritten. Never argue from a clean log that the fault did not occur.
-
-**Why:** Lyra's standard workflow for traceability, and a hard CI gate. A malformed subject is manual rebase work for her, not just a red build.
-
-**How to apply:** Conventional form on every commit in every repo; the ticket scope additionally on every commit in a Jira-backed work repo. Format first, repo style second. Run the verification grep before every push. Relates to [[git_check_state]].
+**How to apply:** Whenever creating a branch or committing in any repo. Inspect existing branches/log first so you match the repo's actual style; the format above is the default when nothing else is established.

-  name and object ID had to change. Because `CEO-*` names embed the subscription
-  name, **always re-verify object IDs against live Entra rather than trusting the

-- **Three tenants**, not two: `6f4fe054` (prod, prod JP), `335836de` (staging,
-  staging JP, test), `3eae2746` (dev). Each `wsp-*` name is a distinct object in
-  each tenant.
-- `wsp-staging-cluster-admins` and `wsp-test-cluster-admins` are **empty**, so
-  `wsp-owner` is the _only_ path to `cluster-admin` in staging. Never drop it before
-  `SuperAdmin-*` is proven — hence the staging branch is split into an additive
-  commit and a cutover commit.
-- **No break-glass exists**: `disableLocalAccounts = True` on every cluster; only the
-  deployment SPNs authenticate non-interactively.
-- Graph **PIM-for-Groups is unreadable via `az`** (the CLI's first-party client lacks

-Two Docker Desktop leftovers break this box, both fatal and both easy to miss:
-
-1. `/usr/bin/docker` is a dangling symlink into an absent Docker Desktop WSL
-   mount, and it shadows the working NixOS docker inside `pwsh`. The script dies
-   with `Program 'docker' failed to run ... No such file`.
-2. `~/.docker/config.json` sets `"credsStore": "desktop.exe"`, a helper that does
-   not exist. `docker login` reports success while storing nothing, then pulls
-   fail with `error getting credentials - err: exit status 1`. Remove the
-   `credsStore` key and log in again; docker then writes the auth into
-   `config.json` itself.
-
-Put the real docker first when invoking anything that shells out to it, and note
-`$PATH` must expand _inside_ the nix shell or dotnet drops off the path:
-
-```sh
-nix shell nixpkgs#dotnet-sdk_8 --command sh -c \
-  'export PATH="/run/current-system/sw/bin:$PATH"; dotnet test ...'
-```
-
-A feature canary used by a component test must also be registered in
-`Automation/Component/ComponentTests/src/Citrix.Wsp.Test.Mocks/WspComprehensive/__files/unleash/unleash-test-environment.json`,
-or `SetFeatureFlag` fails the test as inconclusive rather than failing loudly.

-on the session bus, with the login keyring unlocked at start.

+# Mac Pro 3,1 (Early 2008) — install notes
+
+Flake host: `lyrathorpe-macpro31`. Desktop (`portable = false`, imports
+`../../modules/desktop.nix`). Files: `configuration.nix`,
+`hardware-configuration.nix`.
+
+## Hardware configuration
+
+`hardware-configuration.nix` here is the real config generated by
+`nixos-generate-config` on the machine. Root is an **LVM** logical volume
+(`/dev/mapper/MacPro-Root`, ext4); the ESP (vfat) and swap are referenced by
+UUID. The initrd carries `dm-snapshot` for the LVM root. Regenerate and commit
+if the disk layout changes.
+
+## Bootloader
+
+The Mac Pro 3,1 has **64-bit EFI**, so it uses **systemd-boot** (no GRUB/CSM
+shim). `canTouchEfiVariables = false` because Apple's firmware does not reliably
+accept `efibootmgr` NVRAM writes.
+
+Apple-EFI quirk: if the firmware boot picker does not show NixOS after install,
+either
+
+- uncomment `boot.loader.efi.efiInstallAsRemovable = true;` in
+  `configuration.nix` (installs the fallback `\EFI\BOOT\BOOTX64.EFI`), and/or
+- "bless" the ESP from macOS.
+
+Partition the disk GPT with an ESP (vfat).
+
+## Graphics
+
+The stock card varies between units — **ATI Radeon HD 2600 XT** or **NVIDIA
+GeForce 8800 GT**. No proprietary driver is hardcoded; Sway relies on in-tree KMS:
+
+- ATI Radeon HD 2600 XT → `radeon` (or `amdgpu`) KMS
+- NVIDIA GeForce 8800 GT → `nouveau` KMS
+
+These come up automatically. If a card needs forcing, set
+`services.xserver.videoDrivers` and/or add the module to
+`boot.initrd.kernelModules` for early KMS (see the comment in
+`configuration.nix`).
+
+## Networking
+
+Wired Ethernet via NetworkManager (from `desktop.nix`) — the Mac Pro has two
+gigabit ports.
+
+## Login
+
+Graphical login via a Wayland greeter — `greetd` running ReGreet inside the
+`cage` kiosk compositor — configured centrally in `../../modules/sway.nix` for
+every Sway host (gated on `features.swayDesktop.enable`). The greeter is forced
+to the Dvorak layout to match the console and Sway session. Set the user
+password (`passwd lyrathorpe`) after install, or the greeter cannot
+authenticate. Requires working KMS (radeon/nouveau — see Graphics).
+
+## Apply

+sudo nixos-rebuild switch --flake .#lyrathorpe-macpro31
