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.

+# Working on this flake
+
+Project notes for changes to this repository. Persona and memory rules live in
+the user-global config; this file is about the flake's checks and conventions.
+
+## Before you commit: run the formatter
+
+Formatting and linting are driven by the flake. CI (`.gitea/workflows/ci.yaml`)
+runs `nix flake check`, which fails the build if any file is unformatted or trips
+a lint. From the repo root:
+
+- `nix fmt` — format the whole tree (writes changes).
+- `nix flake check` — run every check read-only (what CI runs).
+- `nix develop` — dev shell; its `shellHook` installs the git pre-commit hooks so
+  the same gates run on `git commit`.
+
+Never commit with `--no-verify`. A bypassed commit ships unformatted content and
+turns CI red on the next push to `main` (see "Docs are checked too").
+
+## What gets checked
+
+Defined in `flake.nix` (the `treefmt`, `pre-commit`, and `checks` blocks) and
+`statix.toml`:
+
+| Check        | Tool                              | Covers                                                  |
+| ------------ | --------------------------------- | ------------------------------------------------------- |
+| `formatting` | treefmt → `nixfmt`                | all `*.nix`                                             |
+| `formatting` | treefmt → `shfmt`                 | shell scripts                                           |
+| `formatting` | treefmt → `prettier`              | **Markdown, YAML, JSON** (incl. `README.md`, this file) |
+| `deadnix`    | deadnix                           | dead Nix bindings (`--no-lambda-pattern-names`)         |
+| `statix`     | statix                            | Nix antipatterns (config in `statix.toml`)              |
+| pre-commit   | nixfmt-rfc-style, deadnix, statix | the same gates, run on commit                           |
+
+Excluded from formatting: `*/hardware-configuration.nix` (generated by
+`nixos-generate-config`) and `flake.lock`. Editor defaults (indent, EOL, final
+newline) are in `.editorconfig`; note Markdown keeps trailing whitespace, which
+encodes hard line breaks.
+
+## 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.
+
+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.
+
+## Host evaluation
+
+CI also evaluates every `nixosConfigurations` / `darwinConfigurations` host's
+toplevel (eval only, no build) on an x86_64 runner, so eval errors fail cheaply.
+Reproduce locally:
+
+```sh
+nix eval --raw ".#nixosConfigurations.<host>.config.system.build.toplevel.drvPath"
+```
+
+Host lists are discovered from the flake, so adding or removing a host needs no
+change to the workflow.

+Each `nixosConfiguration` / `darwinConfiguration` is assembled in `flake.nix`
+from three layers: the shared `baseModules` (or `darwinBaseModules`), the
+per-form-factor and `nixos-hardware` modules listed in the host table, and the
+per-machine `hosts/<Name>/configuration.nix`. Home-manager is wired in as a
+system module; each user's home is composed from the `homeModules` list in that
+host's table entry.
+
+## Module catalogue
+
+Reusable NixOS modules under [`modules/`](./modules). "Imported by" says how a
+module reaches a host: **baseModules** (every NixOS host, via `flake.nix`),
+**host table** (listed explicitly per host in `flake.nix`), or **transitively**
+(pulled in by another module's `imports`).

+| `users.nix`        | baseModules (all NixOS)           | Builds `users.users` from the registry for the host's `hostUsers`; enables zsh; enables Firefox + Thunderbird **only** when `features.swayDesktop.enable` is on. Applies per-user `linger`.               |
+| `features.nix`     | baseModules (all NixOS)           | Declares feature-flag options (currently `features.swayDesktop.enable`) so any host can read/set them without importing the heavy implementation module.                                                  |
+| `workstation.nix`  | transitively (via laptop/desktop) | Form-factor-agnostic base for physical graphical hosts: turns on `swayDesktop`, Dvorak console, PipeWire, firewall (default-deny), fstrim, earlyoom, fwupd, thermald (x86), redistributable fw.           |

+| `sway.nix`         | host table (graphical hosts)      | Implementation of `features.swayDesktop`: the system Sway package, the greetd/ReGreet (cage) greeter forced to Dvorak, xdg-portal, Wayland utility packages. Home-side Sway config is in `home/sway.nix`. |
+| `ssh.nix`          | host table (T400, Mac Pro, RPi5)  | Enables sshd, opens port 22, enforces a key-only policy (no password / keyboard-interactive, no root). Authorized keys come from the registry via `users.nix`.                                            |
+| `firmware/`        | referenced by MBP host config     | Committed Apple peripheral firmware blobs for the Asahi MBP (see "MacBook (Asahi) firmware").                                                                                                             |
+
+Form-factor decision: a **laptop** imports `laptop.nix` (default
+`portable = true`); a **wired desktop** imports `desktop.nix` and sets
+`portable = false`; a **headless server** imports neither (leaves
+`features.swayDesktop.enable` at its default `false`) and adds only what it
+serves. `portable` is threaded through to `home/sway.nix`, which drops the
+battery block and brightness keys on desktops.

+- `docs/mx-re/toolchain-and-plan.md` — the RE toolchain.
+- The **ROM `w2mx_v7.20f_eng.bin`** and the full **SDK + HDK** (manuals as `docs/*.txt`; headers/libs/`bar*.ldd` under `code/SIBOSDK/`; HDK under `code/HDK/`) are on the branch. `/tmp/claude/sibo/` working files (ROM slices, MAME rom dir, Ghidra/decomp output) are transient and reproducible from the toolchain doc.
+
+**Scanner — key result:** the integral laser is driven as an **OO library object** in `SCANNER.DYL` (category token **`oscanner`**) via `p_getlibh` → `p_newsend`/`f_newsend` → `p_send`, over **LIBMANAGER (INT 0x84)** / **MESSMANAGER (INT 0x83)** — NOT raw device I/O. Confirmed on the physical device: `p_open("WL2:D")` + control ops **6** then **7** (`p_iow(chan,6); p_iow(chan,7)`) fire the laser to a good decode (green LED). Default Symbol2 11-byte param block: `04 3f 01 15 06 04 1e 80 0d 0a 06` (decoded output is CR/LF-terminated). Dead ends (do not retry): raw `TTY:D` reads, and the wand `BAR:` / `bar*.ldd` decoders (probe expansion slots → `-41`).
+
+**Blocked on / next step:** the OO **message ordinals + parameter structs** for init / set-params / trigger / read. OLIB assigns ordinals dynamically across the class hierarchy (base classes in `olib`/`hwim`), so they resolve only at runtime — capture them with the **SIBO Debugger on the physical device** (remote debug over serial; it supports breakpoints inside DYLs). MAME cannot inject a barcode, so the last mile must be on hardware. Full step-by-step is in `code/inventory/CONTINUATION.md`.
+
+**RE toolchain (reproducible):** the ROM is MAME machine **`psionwamx`**; run its debugger headless via `xvfb-run -a mame psionwamx -rompath roms -debug -debugscript CMDS -sound none -seconds_to_run N` (MAME lua input injection into the keyboard matrix does NOT work headless — a known limitation). Static: **radare2** (16-bit x86). Decompile: **Ghidra headless** (processor `x86:LE:16:Real Mode`, a Java GhidraScript — Ghidra 12 has no bundled Python). Get MAME/radare2/Ghidra via `nix-shell -p ...`. Details in `docs/mx-re/toolchain-and-plan.md`.
+
+**Fallback to deliver value now:** Phase 2 (the DBF inventory: add stock, consume by quantity) can be built with keyboard UPC entry against `docs/reference/05-filesystem-dbf.md`, dropping the scanner in behind the same interface once retrieval is finished. [[docs-keep-updated]]

+# macOS (nix-darwin) — `lyrathorpe-mac`

+Flake host: `lyrathorpe-mac` (`aarch64-darwin`). Apple Silicon Mac managed by
+**nix-darwin** from this same flake. Built via `mkDarwinHost` (single-user —
+macOS owns the account; identity still comes from the registry). Files:
+`configuration.nix`.
+
+## What this host is
+
+A macOS workstation. The interactive user environment (shell, git, editor,
+Claude) is the **shared `../../home` bundle** — the same modules the Linux hosts
+use — so the terminal experience matches. The Linux-only `desktop.nix`/`sway.nix`
+are intentionally left out. This host config covers the macOS-specific layer:
+system packages, Homebrew, and macOS UI defaults.
+
+## Package sourcing
+
+- **nixpkgs** (`environment.systemPackages`) for CLI tooling and libraries.
+- **Homebrew**, owned declaratively by `nix-homebrew` (Rosetta enabled for
+  x86_64 formulae). The `brews`/`casks` lists are **authoritative**:
+  `onActivation.cleanup = "zap"` uninstalls anything not declared. GUI apps are
+  casks (nixpkgs darwin GUI support is unreliable); a few version-pinned
+  toolchains and the PWA host stay on brew for continuity.
+- **Mac App Store** apps are **not** declarative: nix-darwin 26.05 runs
+  activation as root, and `mas` cannot reach the App Store session from root.
+  Install them by hand with `mas install <id>` from a GUI Terminal (the `mas`
+  CLI is in `environment.systemPackages`).
+
+## macOS integration
+
+- `security.pam.services.sudo_local` — **Touch ID for sudo** (and
+  `darwin-rebuild`'s sudo prompt), kept in `sudo_local` so it survives OS
+  updates. `reattach` pulls in `pam_reattach` so Touch ID works inside tmux
+  (which the terminals auto-start).
+- `system.defaults` — declarative dock / finder / global / trackpad preferences,
+  applied on activation and reversible. This is the main reason to run nix-darwin
+  beyond package management.
+- The JetBrainsMono Nerd Font is installed to `/Library/Fonts`; set it in
+  iTerm2 (Settings → Profiles → Text → Font) so the tmux statusline glyphs
+  render.

+# Work WSL box — `emmathorpe-edaas`
+
+Flake host: `emmathorpe-edaas` (`x86_64-linux`). NixOS running under
+**NixOS-WSL** on the corporate Windows machine. Headless: no Sway desktop
+(`features.swayDesktop.enable = false`), plain WSL shell login. Files:
+`configuration.nix`.
+
+## What this host is
+
+The day-to-day work environment. It layers the corporate Kubernetes / Helm /
+Terraform / cloud toolchain and a couple of work-only editor language servers on
+top of the shared home profile. The system config here is thin — it is mostly
+WSL plumbing; the user-facing tooling lives in
+[`../../users/emmathorpe/work.nix`](../../users/emmathorpe/work.nix).
+
+## WSL specifics
+
+- `wsl.enable`, default user `emmathorpe`, Windows PATH interop and start-menu
+  launchers on. `/etc/hosts` generation is off (`generateHosts = false`).
+- **Docker Desktop integration**, not the native daemon as the primary path:
+  `wsl.extraBin` shims the coreutils/`groupadd`/`usermod` binaries Docker
+  Desktop's `wsl-distro-proxy` expects, and `docker-desktop-proxy.script` is
+  patched to the real proxy path. The native `virtualisation.docker` is also
+  enabled (with `enableOnBoot` + `autoPrune`).
+- `programs.ssh.systemd-ssh-proxy.enable = false` — the NixOS-WSL store is a
+  read-only VHD owned by `nobody`, and OpenSSH rejects the generated
+  `ssh-proxy` Include as "Bad owner or permissions", which would break ssh/git
+  for every command. The vsock proxy it provides is unused under WSL.
+- `networking.hostName = "emmathorpe-edaas"` matches the flake attribute so
+  `nh os switch` resolves without `-H`.
+
+## Renovate review timer
+
+The host-table entry sets `users.emmathorpe.linger = true` so the user's
+`systemd --user` instance stays alive without an open login session. That keeps
+the daily headless **Renovate PR review** timer firing — defined in
+[`../../users/emmathorpe/renovate-review.nix`](../../users/emmathorpe/renovate-review.nix)
+(imported only from `work.nix`, so it exists on this machine alone). See that
+file's header for the auth (Vertex AI ADC), triage policy, and caveats.
+
+## stateVersion
+
+`system.stateVersion = "24.11"` — the release this box was first installed on.
+Leave it; it freezes stateful defaults and is not meant to track the current
+nixpkgs.
+
+## Apply
+
+```sh
+sudo nixos-rebuild switch --flake .#emmathorpe-edaas
+# or, since the hostname matches the attribute:
+nh os switch
+```
