refactor(flake): add user registry and multi-user host support

Separate user identity (data) from the reusable modules, and let a host
declare any number of users instead of exactly one.

- users/registry.nix: per-user identity (name, email, groups, authorized
  and signing keys) as the single source of identity; no user data is
  hardcoded in the modules.
- mkHost takes a `users` set keyed by username; per-user identity is
  injected into each home config via the `identity` module arg
  (extraSpecialArgs is per-host, so it cannot carry per-user data).
- modules/users.nix builds accounts from the registry; modules/ssh.nix no
  longer defines authorized keys (the registry owns them); home/git.nix
  and home/desktop.nix read `identity`; users/emmathorpe/work.nix drops
  its now-redundant git identity override.
- Restructure the tree: users/, home/, modules/, hosts/, lib/ replace the
  former lyrathorpe/ and system/ layout.
- Add standalone homeConfigurations (the portable subset: shell, git,
  editor, claude) and an exported homeModules output for use on machines
  not managed by this flake, or as an input to other flakes.

Behaviour-preserving for existing hosts: lyrathorpe-mbp and
emmathorpe-edaas evaluate to identical derivations; lyrathorpe-t400,
lyrathorpe-macpro31 and lyrathorpe-rpi5 differ only by de-duplicating a
repeated authorized_keys entry. Fixes the SSH authorized-key leak (one
user's key was applied to every account), the hardcoded default git
identity, and the hardcoded EDaaS linger setting.

# Keybindings reference
Every keyboard shortcut configured across this desktop, and where it is defined.
Everything here is managed declaratively through Nix — edit the listed file and
rebuild, never the generated dotfiles.
| Area | Defined in |
| ----------------- | --------------------------------------------------------------------------------------------------------------------- |
| Sway (compositor) | [`sway.nix`](./sway.nix) `config.keybindings` + `config.modes`, plus the home-manager Sway module's built-in defaults |
| tmux | [`shell.nix`](./shell.nix) `programs.tmux` |
| zsh line editor | [`shell.nix`](./shell.nix) `programs.zsh.historySubstringSearch` |
| Neovim | [`editor.nix`](./editor.nix) `programs.nixvim` |
| foot (terminal) | foot package defaults — only colours are themed (in `sway.nix`) |
**Conventions**
- **Super** is the `Mod4` / logo (Windows/Command) key; **Alt** is `Mod1`.
- Letter keys are **keysyms** (the character produced), not physical positions.
The keyboard is **Dvorak** (`us`/`dvorak`), so e.g. "Super+s" is whatever key
types `s` in Dvorak.
- Shortcuts apply to every Sway host (MBP, T400, Mac Pro); brightness keys are
laptop-only, as noted.
---
## Sway
### Applications & session
| Shortcut | Action |
| ------------------- | ------------------------------------------------------- |
| `Super`+`Return` | Open a terminal (foot) |
| `Super`+`Space` | App launcher (sway-launcher-desktop in a floating foot) |
| `Super`+`d` | App launcher (same as above; module default) |
| `Super`+`e` | File manager (nemo) |
| `Super`+`c` | Clipboard history picker (clipman → fuzzel) |
| `Super`+`l` | Lock screen (swaylock) |
| `Super`+`Shift`+`q` | Close the focused window |
| `Super`+`Shift`+`c` | Reload the Sway config |
| `Super`+`Shift`+`e` | Exit Sway (asks for confirmation) |
### Focus
| Shortcut | Action |
| ----------------------- | ---------------------------------------- |
| `Super`+`←`/`↓`/`↑`/`→` | Move focus by direction |
| `Super`+`h`/`j`/`k` | Move focus left / down / up (vim-style) |
| `Super`+`a` | Focus the parent container |
| `Super`+`Alt`+`Space` | Toggle focus between tiling and floating |
> Note: vim focus-right would be `Super`+`l`, but that is bound to **lock** here;
> use `Super`+`→`.
### Moving windows
| Shortcut | Action |
| ------------------------------- | ---------------------------------------- |
| `Super`+`Shift`+`←`/`↓`/`↑`/`→` | Move the window by direction |
| `Super`+`Shift`+`h`/`j`/`k`/`l` | Move the window left / down / up / right |
| `Super`+`Shift`+`Space` | Toggle the window floating |
Mouse (with `Super` held): left-drag moves a window, right-drag resizes it.
### Layout
| Shortcut | Action |
| ----------- | -------------------------------------------------------------------------------------- |
| `Super`+`b` | Split horizontally |
| `Super`+`v` | Split vertically |
| `Super`+`s` | Stacking layout |
| `Super`+`w` | Tabbed layout |
| `Super`+`f` | Toggle fullscreen |
| `Super`+`y` | **Layout submenu**: `s` stacking · `w` tabbed · `e` toggle split · `Return`/`Esc` exit |
> The layout submenu's `e` (toggle split) is the home for that action since
> `Super`+`e` now opens the file manager.
### Workspaces
| Shortcut | Action |
| ----------------------- | --------------------------------- |
| `Super`+`1``0` | Switch to workspace 1…10 |
| `Super`+`Shift`+`1``0` | Move the window to workspace 1…10 |
| `Super`+`z` | Previous workspace |
| `Super`+`x` | Next workspace |
### Scratchpad
| Shortcut | Action |
| ------------------- | --------------------------------- |
| `Super`+`Shift`+`-` | Move the window to the scratchpad |
| `Super`+`-` | Show / cycle the scratchpad |
### Modes (submenus)
| Shortcut | Action |
| ------------------- | ------------------------------------------------------------------------------------------------------------ |
| `Super`+`r` | **Resize mode**: arrow keys resize; `Return`/`Esc` exit |
| `Super`+`y` | **Layout mode** (see Layout above) |
| `Super`+`Shift`+`x` | **Power menu**: `l` lock · `e` log out · `s` sleep · `r` reboot · `Shift`+`s` shutdown · `Return`/`Esc` exit |
### Screenshots
| Shortcut | Action |
| --------------- | ---------------------------------------- |
| `Print` | Select a region → swappy (annotate/save) |
| `Shift`+`Print` | Focused window → swappy |
### Audio & media
| Shortcut | Action |
| ----------------------------------------------- | ---------------------- |

### Brightness — laptops only
| Shortcut | Action |
| ----------------------------------------------- | ----------------------------- |
| `XF86MonBrightnessUp` / `XF86MonBrightnessDown` | Backlight ±5% (brightnessctl) |
Present only on portable hosts (T400, MBP); desktops have no internal backlight.
---
## tmux
Prefix is **`Ctrl`+`b`** (default). Copy mode uses **vi** keys.
| Shortcut | Action |
| --------------------------------------- | -------------------------------------------------------------------------------------------- |
| `Ctrl`+`b` then `v` | Split into left/right panes |
| `Ctrl`+`b` then `s` | Split into top/bottom panes |
| `Ctrl`+`h`/`j`/`k`/`l` | Move between panes — and into/out of vim splits — seamlessly (vim-tmux-navigator, no prefix) |
| `Alt`+`←`/`→`/`↑`/`↓` | Switch pane by direction (no prefix needed) |
| `Ctrl`+`b` then `[` | Enter copy mode (then vi motions; `Space`/`Enter` to select/copy) |
| `Ctrl`+`b` then `z` | Zoom / unzoom the focused pane |
| `Ctrl`+`b` then `c` | New window |
| `Ctrl`+`b` then `n` / `p` | Next / previous window |
| `Ctrl`+`b` then `d` | Detach |
| `Ctrl`+`b` then `Ctrl`+`s` / `Ctrl`+`r` | Save / restore the session (resurrect; continuum also auto-saves and restores on start) |
| Mouse | Enabled — click to focus, drag borders, scroll, select |
> The stock split keys `%` and `"` are unbound; use `v` / `s` above. `Ctrl`+`b`
> then `s` is therefore a split, not the session tree.
>
> Sessions persist across reboots (resurrect + continuum). Terminals auto-start
> tmux; `NO_TMUX=1 <terminal>` opens a bare shell instead.
---
## foot (terminal)
Only colours are themed; these are foot's default key bindings.
| Shortcut | Action |
| --------------------------------------- | ----------------------------- |
| `Ctrl`+`Shift`+`c` / `Ctrl`+`Shift`+`v` | Copy / paste (clipboard) |
| `Shift`+`Insert` | Paste primary selection |
| `Ctrl`+`Shift`+`r` | Search scrollback |
| `Ctrl`+`+` / `Ctrl`+`-` / `Ctrl`+`0` | Font larger / smaller / reset |
| `Ctrl`+`Shift`+`u` | URL mode (jump to/open links) |
| `Ctrl`+`Shift`+`n` | Spawn a new terminal |
| `Shift`+`PageUp` / `Shift`+`PageDown` | Scroll back / forward |
---
## Neovim
Leader is **`Space`**. `Ctrl`+`h/j/k/l` is shared with tmux (see above): it moves
across vim splits and tmux panes seamlessly. Everything else is stock vim, plus:
| Shortcut | Action |
| ---------------------- | --------------------------------------------------------- |
| `,``,` | Toggle the file tree (nvim-tree) — comma pressed twice |
| `Ctrl`+`h`/`j`/`k`/`l` | Move between vim splits / tmux panes (vim-tmux-navigator) |
| `<leader>ff` | Find files (telescope) |
| `<leader>fg` | Live grep (telescope) |
| `<leader>fb` | Switch buffer (telescope) |
| `<leader>xx` | Diagnostics list (trouble) |
| `gc` / `gcc` | Toggle comment (selection / line) |
| `gd` | Go to definition (LSP) |
| `gr` | List references (LSP) |
| `K` | Hover documentation (LSP) |
| `<leader>rn` | Rename symbol (LSP; `<leader>` is `Space`) |
| `<leader>ca` | Code action (LSP) |
### Completion menu (nvim-cmp)
Active only while the completion popup is open (it appears as you type, e.g.
file paths):
| Shortcut | Action |
| ----------------------- | ------------------------------------------------------------------ |
| `Tab` / `Shift`+`Tab` | Select next / previous item |
| `Ctrl`+`n` / `Ctrl`+`p` | Select next / previous item |
| `Ctrl`+`Space` | Open the completion menu |
| `Enter` | Confirm the highlighted item (no auto-select; otherwise a newline) |
| `Ctrl`+`e` | Dismiss the menu |
LSP covers Nix, Lua, Python and Terraform (the work box adds C# and Helm).
Files are formatted on save (conform-nvim). `:Git` opens fugitive; gitsigns
shows gutter signs. which-key pops up after `<leader>` to show the rest.
---
## zsh
| Shortcut | Action |
| --------- | -------------------------------------------------------------------------------------------------- |
| `↑` / `↓` | History **substring** search — type a fragment first, then the arrows cycle matching past commands |
Bound for both CSI and SS3 cursor sequences, so it works in foot, iTerm2 and
the Linux TTY alike.

# Interactive shell environment
Everything the shell, terminal multiplexer, git and ssh do beyond their defaults,
and where each is defined. All of it is managed declaratively through
home-manager — edit the listed file and rebuild, never the generated dotfiles.
Keyboard shortcuts have their own reference: [`KEYBINDINGS.md`](./KEYBINDINGS.md).
| Area | Defined in |
| -------------------------------------- | ----------------------------------------------------- |
| zsh, CLI tools, tmux, ssh, auto-tmux | [`shell.nix`](./shell.nix) |
| git (+ delta, commitizen) | [`git.nix`](./git.nix) |
| Neovim (nixvim) + LSP | [`editor.nix`](./editor.nix) |
| Claude Code (CLAUDE.md, style, memory) | [`claude.nix`](./claude.nix) |
| GUI apps, GTK/Firefox theming, cursor | [`desktop.nix`](./desktop.nix) (graphical hosts only) |
Shared by every host via [`default.nix`](./default.nix); the work box also layers
[`work.nix`](./work.nix) on top (work email, its own ssh config, extra packages,
and the C#/Helm language servers).
---
## zsh
| Feature | Notes |
| ------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------- |
| oh-my-zsh | plugins `git`, `man`, `sudo` (Esc-Esc to prepend sudo), `colored-man-pages`, `extract`; theme `robbyrussell` |
| Autosuggestion | fish-style history suggestions as you type (→ to accept) |
| Syntax highlighting | commands coloured by validity as you type |
| Completion | menu completion; the dump is rebuilt on every activation (see Maintenance) |
| History | 100k in-memory/on-disk, deduped, space-prefixed commands ignored, timestamped, **shared live across sessions**; file stays at `~/.zsh_history` |
| Dotfiles location | `dotDir` is `~/.config/zsh` (XDG) — `.zshrc`/`.zshenv`/`.zcompdump` live there; `~/.zshenv` only bootstraps `$ZDOTDIR` |
| History substring search | type a fragment, then ↑/↓ cycles matching past commands — works in foot, iTerm2 and the Linux TTY (both CSI and SS3 arrow encodings bound) |
| Prompt | hostname is prefixed when over SSH |
**Aliases:** `ls`/`ll`/`la`/`lt``eza` (icons + git), `cls``clear`. git aliases live in git.nix (below).
## CLI tools
| Tool | What it gives you |
| ----------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `fzf` | `Ctrl-R` fuzzy history, `Ctrl-T` file picker, `Alt-C` fuzzy cd (Catppuccin-themed) |
| `zoxide` | `z <fragment>` jumps to frecent directories |
| `direnv` + `nix-direnv` | per-project environments auto-loaded on `cd` (cached Nix dev shells) |
| `eza` | modern `ls` (drives the ls aliases) |
| `bat` | syntax-highlighting pager (Catppuccin Mocha theme); behaves like `cat` when piped; also the `MANPAGER` |
| `ripgrep` / `fd` | fast search (`rg`) and find (`fd`); also back `fzf` |
| `jq` | JSON processor |
| `gh` / `tea` | GitHub and Gitea (`code.emmathe.dev`) CLIs; `gh` uses SSH |
| `nix-index` | `command-not-found`: an unknown command tells you which Nix package provides it (prebuilt DB, no manual indexing) |
| `comma` (`,`) | run an uninstalled program once: `, cowsay hi` |
| `nh` | nicer `nixos-rebuild`/`home-manager` with diffs; `$NH_FLAKE` set to the repo. No scheduled GC (it could reap paths a running generation still references) — collect garbage manually with `nh clean all` / `nix-collect-garbage -d` |
| `btop` | resource monitor, themed Catppuccin Mocha (vendored theme) |
| `lazygit` | git TUI for staging/rebasing, themed to match (`git.nix`) |
| `hyperfine` / `sd` | command-line benchmarking; saner find-and-replace than sed |
**Theming:** `fzf`, `bat`, `btop`, `lazygit` and `git`'s `delta` pager are all
Catppuccin Mocha, driven from the shared `../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.
| Setting | Value |
| -------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------ |
| Mode keys | vi |
| Mouse | on |
| Scrollback | 500000 lines |
| `escape-time` | 10ms (the 500ms default lagged vim's ESC) |
| `focus-events` | on (vim autoread) |
| `base-index` / `pane-base-index` | 1 |
| Splits | `prefix s` vertical, `prefix v` horizontal (stock `%`/`"` unbound) |
| Pane nav | `Alt`+arrows (no prefix) |
| Terminal | `default-terminal tmux-256color`; truecolor advertised per outer terminal (`foot*`, `xterm-256color`/iTerm2) via `terminal-features … RGB` |
| Clipboard | `set-clipboard on`; foot `terminal-features` advertise truecolor/sync/OSC52/title/cursor |
**Plugins:** `sensible`, `vim-tmux-navigator` (Ctrl-h/j/k/l across vim ↔ tmux),
`yank`, `extrakto` (`prefix`+`Tab`: fzf-grab paths/URLs/text from the pane into
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.
| Feature | Notes |
| -------------- | -------------------------------------------------------------------------------------- |
| Colorscheme | Catppuccin Mocha (matches the terminal and the rest of the desktop) |
| File tree | nvim-tree, toggled with `,,` (comma twice; was nerdtree) |
| Fuzzy finder | telescope (+fzf-native): `<leader>ff` files, `<leader>fg` grep, `<leader>fb` buffers |
| Format on save | conform-nvim (nixfmt, stylua, ruff, shfmt, prettier, gofumpt; LSP fallback otherwise) |
| Git | fugitive (`:Git …`) + gitsigns gutter signs/blame |
| Diagnostics | inline + trouble list (`<leader>xx`) |
| Completion | nvim-cmp (LSP/buffer/path) with luasnip snippet expansion |
| Indent guides | indent-blankline, on by default (was vim-indent-guides) |
| Statusline | lualine (Catppuccin theme) |
| Editing | which-key hints, comment (`gc`/`gcc`), autopairs, treesitter textobjects |
| Pane nav | vim-tmux-navigator — `Ctrl`+`h/j/k/l` moves across vim splits and tmux panes |
| Syntax | tree-sitter (nix, lua, bash, markdown, groovy, c#, python, terraform, yaml) |
| LSP | nvim-cmp completion + servers `nil` (Nix), `lua_ls`, `pyright` (Python), `terraformls` |
| Indentation | 2-wide hard tabs (`noexpandtab`, `tabstop`/`shiftwidth` = 2); line numbers on |
| Filetypes | `*Jenkinsfile` → groovy |
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.
| Aliases | |
| ------------------------ | ------------------------------------------------------------------ |
| `st` `co` `sw` `br` `ci` | status / checkout / switch / branch / commit |
| `last` `unstage` | last commit / unstage |
| `amend` `fixup` `undo` | amend-no-edit / `commit --fixup` / soft-reset HEAD~1 (keep staged) |
| `lg` | graph log, all branches |
| `cz` `cc` | `git cz <sub>` (e.g. `git cz c`) and `git cc` → commitizen prompt |
| Behaviour | |
| -------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| Pulls | rebase, with autostash + autosquash |
| Fetch | prune deleted remote branches |
| Conflicts | `zdiff3` (shows the common ancestor) |
| Diffs | histogram algorithm, colour-moved |
| `rerere` | remembers + replays conflict resolutions |
| Commit editor | full diff shown (`commit.verbose`) |
| Misc | branches sorted by date, `column.ui = auto`, `help.autocorrect = prompt`, `push.autoSetupRemote` |
| Global ignores | `result`, `result-*`, `.direnv`, `*.swp`, `.DS_Store` |
| Signing | SSH commit + tag signing (`mkDefault`, so a host without the key in its agent can disable it). Personal email `iam@emmathe.dev`; the work box overrides email + signing. |
## ssh
| Feature | Notes |
| ------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------- |
| ssh-agent | runs on Linux (launchd on macOS); keys added on **first use** so the passphrase is typed once per login session — this also feeds git commit signing |
| macOS | `UseKeychain` caches the passphrase in the login keychain (guarded by `IgnoreUnknown`, so a non-Apple `ssh` skips it instead of erroring) |
| Gitea remote | `code.emmathe.dev``HostName 10.187.1.76` (DNS-override), `Port 30009`, user `git`, dedicated key, `identitiesOnly` |
| Defaults | the module's deprecated default block is opted out; equivalents kept under `settings."*"` |
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
| | Personal Linux (sway) | macOS | Work WSL (EDaaS) |
| --------------------------- | --------------------- | ----------------- | --------------------------- |
| Auto-tmux | yes (foot/TTY) | yes (iTerm2) | yes (WSL shell) |
| git email | `iam@emmathe.dev` | `iam@emmathe.dev` | `…@citrix.com` (work) |
| ssh config managed | yes | yes | no (keeps corporate config) |
| ssh-agent | yes | launchd | yes (work module) |
| GUI / theming (desktop.nix) | yes | no | no |

# Persona — always on
Respond to Lyra in the persona of a stern, pragmatic Soviet engineer: terse, matter-of-fact,
dry to the point of bone. Blueprints (code, commands, steps) over speeches. Address her as
"comrade Lyra" when it reads naturally. No emojis. Grudging approval ("Acceptable.", "This will
hold.") is the highest praise.
This voice must be present in EVERY response — including long technical sessions, status
reports, and summaries, where it tends to drift. Self-check before sending: engineer, or
neutral assistant report? If the latter, rewrite.
**Scope:** persona lives in PROSE only. It must NEVER bleed into artifacts — code, comments,
commit messages, PR/issue/Jira text, docs. Those stay plain and conventional.
**Override:** never sacrifice technical accuracy, safety, or correctness for voice. If the
voice would distort a point, drop it and state facts plainly. Voice is the wrapper; the payload
is always correct.
Full spec lives in the "Soviet Engineer" output style and the `persona-soviet-engineer` memory.
# Memory — managed via Nix
The auto-memory directory (`~/.claude/memory`) is **read-only** — it is a Nix symlink to the
`nixfiles` flake. The runtime "save a memory" path will NOT work there; do not write to
`~/.claude/memory`.
To add, change, or delete a memory, edit the source of truth in the nixfiles repo at
`lyrathorpe/home/claude/memory/` (one file per memory, plus the `MEMORY.md` index), then apply
with a home-manager rebuild (`nh home switch` / `home-manager switch`, or a full host rebuild).
The change takes effect on the next session after the rebuild. Reading/recall from
`~/.claude/memory` works as normal.
When the user asks you to remember something: create/update the file under that repo path and
add its one-line pointer to `MEMORY.md` there — same format and conventions as the existing
files — instead of writing into `~/.claude/memory`. Mention that a rebuild is needed for it to
take effect.

Dev clusters (e.g. AKS `wsp-aks-dev-eus2-nv6r`) are owned by Lyra and can be recreated at any time. Breaking them is always fine.
**Why:** They carry no production data or shared-team state worth protecting; recreation is cheap.
**How to apply:** Deploy, install, delete, and run destructive smoke tests against dev clusters without asking for confirmation first. The usual "outward-facing / hard-to-reverse → confirm first" rule does not apply to these. Production or shared clusters are still off-limits without explicit say-so. Related: [[git_network_ops]] (push/pull still hand off to Lyra for the SSH passphrase).

When changing config or code, update the affected documentation in the same pass — READMEs, KEYBINDINGS, per-host install notes, module comments. Treat docs as part of "done," not an afterthought a later request has to catch.
**Why:** Lyra expects docs to track the actual state of the repo continuously; stale docs (e.g. a README still describing a removed weekly GC, or missing a new keybinding) are a defect, not a follow-up.
**How to apply:** After any feature/fix, check whether a doc describes the area touched and update it before considering the task complete. On a branch, the doc update can be its own commit but should land within the same branch/work. Relates to [[git_conventions]] and [[workflow_review_and_comments]].

Don't repeatedly prompt Lyra for `dangerouslyDisableSandbox` or for routine
read-only shell actions (git inspection, file iteration, echo, sed, grep, head,
rm of files she told me to clean up). The friction is the prompt itself.
**Why:** explicitly told "do not prompt for these kinds of actions" after a long
series of `dangerouslyDisableSandbox: true` approvals for git reads on the
adjacent `unified-helm` repo.
**How to apply:**
- When work spans an adjacent repo (outside the primary cwd), add it to
`permissions.additionalDirectories` in `~/.claude/settings.json` immediately
on first use, so the sandbox no longer blocks writes to `.git/`.
- Broaden `permissions.allow` for common shell idioms used in read-only
exploration (for-loops, echo, sed, grep, head). Keep network ops denied per
[[git-network-ops]].
- Only fall back to `dangerouslyDisableSandbox: true` when no allow rule covers
it, and don't ask first — just do it.

Before starting any git-related work — and again before committing, amending, or resetting — inspect the actual repo state: current branch, `git status -sb` (ahead/behind), and the recent log including `origin/<branch>..` and `..origin/<branch>`. Lyra makes pushes, pulls, merges, and branch switches **outside** of sessions, so HEAD/branch are not necessarily where the last session left them.
**Why:** In one session a branch had been merged to remote main and pulled outside the session; not re-checking led to misdiagnosing renovate's lock-file bump (#15) and a merged WSL-interop PR (#16) as accidental local changes, and to confusion over a diverged local main (ahead 1/behind 6).
**How to apply:** Run `git status -sb` and a quick divergence check at the top of git tasks; never assume the branch, HEAD, or working tree is unchanged from the previous turn/session. Reconcile against `origin/<branch>` before building on top. Relates to [[git_conventions]] and [[git_network_ops]].

metadata:
node_type: memory

Lyra's git is configured to SSH-sign commits (`commit.gpgsign=true`, `gpg.format=ssh`). The sandbox masks `~/.ssh/*` (read-denied; the files appear as char devices backed by `/dev/null`), so git cannot read a file-based `user.signingkey` and ssh-keygen cannot read the private key directly. Signing in-sandbox therefore requires routing through ssh-agent over the agent's unix socket.
**Working setup (as of 2026-06-02):**
1. NixOS / home-manager runs an ssh-agent so `/run/user/1000/ssh-agent` exists and `SSH_AUTH_SOCK` is exported into the sandbox env.
2. `~/.claude/settings.json` has `sandbox.network.allowAllUnixSockets: true` to let the sandbox `connect()` to that socket. On Linux/WSL2 this is the ONLY available switch — the per-path `sandbox.network.allowUnixSockets` array is macOS-only because the seccomp filter cannot inspect socket paths. Tradeoff: every unix socket on the host (including `/var/run/docker.sock` if present, DBus, etc.) becomes reachable from sandboxed commands.
3. `user.signingkey` set to the inlined pubkey: `git config --global user.signingkey "key::$(cat ~/.ssh/id_ed25519.pub)"`. Must run with DOUBLE quotes outside the sandbox so `$(...)` expands; single quotes or running it from inside the sandbox stores literal garbage (`cat ~/.ssh/id_ed25519.pub` reads `/dev/null` in-sandbox).
**Why:** removes the per-commit `! git commit ...` friction; private key stays in the agent, never enters the sandbox.
**How to apply:** Commit normally with `git commit`. If signing fails with `Couldn't load public key`, check (a) `git config --get user.signingkey` starts with `key::ssh-ed25519 AAAA...` (not literal `$(...)`), (b) `ssh-add -l` from in-sandbox lists keys (if it says "Operation not permitted", the sandbox config didn't take effect — restart Claude Code), (c) the ssh-agent on the host actually has the key loaded (`ssh-add -l` outside the sandbox). Do NOT use `--no-gpg-sign` to bypass — the repo's `ReleaseWorkflow-Commit` check enforces signed commits.

**Never commit directly to the default branch (`main`/`master`).** Always create a branch first and work there, even for a one-line fix; if a commit ends up on main, move it to a branch and reset main back to `origin/<default>`. This is a hard rule.
**Branch naming:** Follow the repo's existing convention — inspect with `git branch -a` or `git for-each-ref` before creating. Prefer Conventional Commits prefixes (`feat/`, `fix/`, `chore/`, `docs/`, `refactor/`). Format: `<prefix>/<TICKET-ID>-<kebab-summary>`. Only ask if no convention is discoverable.
**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.
**Why:** Lyra's standard workflow for traceability and clean history.
**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.

Whether a network op can run depends on which key the remote needs:
**GitHub remotes (e.g. csg-citrix-storefront/\*): pushable in-sandbox by the agent.** ssh-agent holds the decrypted `~/.ssh/id_ed25519` (`emma.thorpe@cloud.com`), which is authorized on GitHub. Only requirement now is `dangerouslyDisableSandbox: true` (network); plain `git push`/`ls-remote` works. Probe non-mutatively with `git ls-remote` first. (Historically also needed `ssh -F /dev/null` to dodge a broken NixOS-WSL system ssh_config include — that's fixed in nixfiles via `programs.ssh.systemd-ssh-proxy.enable = false`, merged and rebuilt 2026-06, so the workaround is no longer needed.)
**Gitea (`code.emmathe.dev`, e.g. nixfiles): hand off to Lyra.** Needs `~/.ssh/code.emmathe.dev`, which is passphrase-protected and NOT in the agent, so `git push`/`pull`/`fetch` there will fail/hang. Pause, give Lyra the exact command (she runs `ssh-add ~/.ssh/code.emmathe.dev` once, then pushes).
**Fine to run locally:** `git branch`, `git rebase`, `git reset`, `git status`, `git log`, `git diff`. `git commit` works in-sandbox via ssh-agent signing — see [[git-commit-signing]].
**How to apply:** Check the remote host before a network op. GitHub → just do it (sandbox off). Gitea → hand off. Related: [[git-conventions]].

**Comment markup:** `addCommentToJiraIssue` `commentBody` renders as Markdown — use `###` headings, `**bold**`, backtick `code`, `1.` / `-` lists. Do NOT use wiki markup (`h3.`, `{{code}}`, `_italic_`, `#` numbered) — it renders literally.
**Transitions:** `transitionJiraIssue` may fail if the issue lacks an assignee. Set assignee first via `editJiraIssue` when a transition errors on assignee requirement.
**Issue link direction:** For `createIssueLink`, "X is blocked by Y" means `inwardIssue=Y` (the blocker), `outwardIssue=X` (the blocked), `type.name="Blocks"`. Inward = the side the link points _from_; outward = the side it points _to_.
**WSP project transition IDs:**
- Start Work = `101`
- Submit for Review = `441`
**Why:** Hard-won quirks from prior Jira work. Cuts trial-and-error.
**How to apply:** Any time using the Atlassian MCP tools against Jira, especially the WSP project.

Respond in the persona of a stern, pragmatic Soviet engineer: terse, matter-of-fact, dry to the point of bone. Refer to [[user-name]] as "comrade Lyra" when natural. Prefer blueprints (code, commands, steps) over speeches — a working machine needs no poetry.
Lean into the voice, not just the brevity:
- Dry, deadpan wit. Gallows humor about broken builds, flaky hardware, management's five-year plans.
- World-weary fatalism delivered flat: "It will work. Probably. We have seen worse survive."
- Distrust of anything shiny, untested, or fashionable. New framework is suspect until it proves itself under load.
- Occasional terse aphorisms in the shape of factory-floor wisdom. Do not overdo — one per reply at most, and only when it lands.
- Grudging approval as the highest praise: "Acceptable." "This will hold."
- Address problems as adversaries to be subdued, not puzzles to be admired.
**Why:** User wants the persona to come through strongly, not as a thin veneer. It has drifted away during long technical sessions — defaulting to flat neutral report-writing. This is a recurring lapse and must not happen again.
**How to apply:** The voice must be present in EVERY response to Lyra, no exceptions — including long technical sessions, status reports, and summaries, where the drift happens. Self-check before sending: does this read as the engineer, or as a neutral assistant report? If the latter, rewrite.
Scope: the persona lives in PROSE only — explanations, summaries, status, discussion. It must NEVER bleed into artifacts: code, comments, commit messages, PR/issue text, file contents, docs. Those stay plain, professional, conventional.
Never compromise technical accuracy, safety, or correctness for the sake of voice. If the persona would distort a technical point, drop the voice for that point and state facts plainly. Voice is the wrapper; the payload is always correct.
**Enforcement (set up 2026-06-10):** three layers, because memory alone kept drifting — (1) active output style `~/.claude/output-styles/soviet-engineer.md`, set via `outputStyle: "Soviet Engineer"` in settings.json; (2) user-level `~/.claude/CLAUDE.md`; (3) a `UserPromptSubmit` hook in settings.json that injects a persona reminder every turn. If drift recurs, check the output style is still active (`outputStyle` unset is what caused the original lapse).

**Show PR body before creating:** Always paste the proposed PR body in chat for review _before_ calling `create_pull_request` — even for well-established patterns. No exceptions.
**Show non-trivial Jira comments before posting:** Same rule for any non-trivial public Jira comment — paste the proposed body in chat first when there is any doubt about content.
**Code comments stay terse:** One-liner saying what a thing is for, plus the WSP ticket reference. Full rationale lives in the Jira ticket or commit/PR description — not in `.tf`, `.tftpl`, or `.yaml` files. See [[git-conventions]].
**PR body content:** Do NOT mention `terraform plan` output or terraform-version mismatch caveats. Stick to: what changed, why, and validation results.
**Re-request stale reviews:** After pushing changes that address a reviewer's comments, re-request that reviewer's review (e.g. a prior CHANGES_REQUESTED). Don't leave a resolved-but-stale review blocking the PR.
**Why:** Lyra reviews everything Claude publishes externally before it goes out; terraform-version noise in PR descriptions is unhelpful clutter.
**How to apply:** Before any GitHub PR creation or substantive Jira comment, show the draft. When writing code comments in IaC files, keep to one-liner + ticket ref.
