refactor(nixos): scope agent guidance

Imported as a linear vendor commit so forge rebases do not replay the upstream root tree.

-# NixOS configuration instructions
-
-## Desktop
-
-- When adding a graphical application, register its workspace icon in `registry.window-icon`.
-  The workspace indicator uses this mapping to show an application icon instead of the generic default glyph.
-  Match the mapping on the window class.
-  Store the icon as the rendered string.
-  Run `hyprctl clients -j | jq -r '.[].class' | sort -u` to list classes in the running session.
-- TODO: Verify this path after the NixOS configuration is migrated.
-  Set Hyprland session environment variables in `modules/desktop/session/hyprland/default.nix` with `env = KEY,VALUE`.
-  `home.sessionVariables` do **not** reach the Hyprland session because UWSM does not source `hm-session-vars.sh`.
-  Source cursor values from `config.stylix.cursor`.
-  Set `XCURSOR_*` and `HYPRCURSOR_*` to the same theme for Bibata.
-
-## Firefox
-
-- Manage Firefox search engines through `programs.firefox.search` with `force = true`.
-  Hide built-in engines with `<engine>.metaData.hidden = true` because omission does not remove them.
-  Use current engine ids, such as `default = "ddg"` instead of `"DuckDuckGo"`.
-  Decode the built `search.json.mozlz4` with `mozlz4a -d <search.json.mozlz4>` to check the result.
-- Avoid Home Manager Firefox extension settings unless the whole profile can use the legacy extension-storage backend.
-  Any non-empty `profiles.<name>.extensions.settings.<id>.settings` sets `extensions.webextensions.ExtensionStorageIDB.enabled = false` for the whole profile.
-
-## Neovim
-
-- Nixvim's flake input follows the root nixpkgs source, but its Home Manager module does not reuse the host's `pkgs` instance.
-  Keep `programs.nixvim.nixpkgs.useGlobalPackages = true`.
-  That setting makes Nixvim use the shared package set without warning that its source default changed.
-
-## AI tooling
-
-- Use produced literals for Herdr key names that include shifted punctuation.
-  For example, use `prefix+<` instead of `prefix+shift+comma`.
-- Put monorepo Pi extension sources in `.pi/extensions/`.
-  Pi discovers them from subdirectories through the local ancestor-resource patch.
-- Treat Home Manager-managed Pi settings as generated output.
-  Do not edit them except for throwaway development or local experiments.
-  Promote finished settings into the NixOS configuration before treating them as deployed.
-
-## Gotchas
-
-- `configs/nixos/registry/stable-uid.nix` receives library functions through `lib`.
-  Qualify its library calls with `lib.`.
-- Guest modules are host-agnostic wiring, while host files own deployment-specific service configuration such as served volumes and host paths.
-  For example, `guests/copyparty.nix` should expose options and translate them into guest mounts/service settings, while `hosts/pikachu/default.nix` chooses `/inbox`, `/media`, and their backing paths.
-  Guest addresses and routes are host-level configuration because a guest module can be used on multiple hosts.
-- `sops.secrets.<name>.owner` must name a user known on the decrypting host.
-  Do not set the owner to a guest-only service user unless the host also declares that user.
-  Use a host-visible owner plus a shared group mode when the guest service can read the decrypted secret file through its group.
-- A read-only guest bind mount cannot contain nested writable bind mounts unless their mount-point
-  directories already exist inside the read-only source.
-  For aggregate Copyparty volumes such as `/srv` with nested `/srv/inbox`, keep the guest bind mount
-  writable and enforce read-only behavior through Copyparty access plus service `ReadWritePaths`.
-- `deploy-to` builds from the source checkout, records the imported closure as the target system profile,
-  and activates it. Do not rely on a target-local monorepo checkout for remote deployment.
-- On Pikachu, `nix copy --to ssh://pikachu` accepted a small `nix store add-file` probe,
-  but rejected locally built system paths that lacked trusted signatures.
-  Use a sudo `nix-store --import` path for unsigned deploy closures.
-- Public DNS entries are not managed through the NixOS configuration.
-  Do not describe NixOS route choices as public-DNS management.
-- Do not hand-author `hardware-configuration.nix` for a host that has not been generated on that machine.
-  Generate it on the target system or live ISO, then stage it before evaluating the flake.
-- Configure the Chaotic Nyx cache only on hosts that select `linuxPackages_cachyos` (currently Neogaia
-  and Zeus), not in the generic host module.
-- Module-relative paths resolve from the module file. Update them when moving a module into a subdirectory.
-- On Pikachu, `uptime` does not support `-s`. Use `who -b` to report the boot time.

+# Caps Escape Design
+
+## Facts
+
+- Commit `250b0b71f` removed `services.xserver.xkb.options` from the shared host module.
+- The removed option was `caps:escape_shifted_capslock`.
+- That XKB option maps Caps Lock to Escape.
+- Shift+Caps Lock still enables Caps Lock.
+- The shared host module configures Neogaia, Zeus, and Pikachu.
+- Zeus has QMK firmware that provides equivalent keyboard behavior.
+- Neogaia and Zeus enable `modules.host.cachyos` and `modules.desktop`.
+- Pikachu enables neither module.
+- `configs/nixos/hosts/neogaia/default.nix` directly sets Neogaia-specific hardware, networking, desktop application, and Waybar settings.
+- The current configuration has no Caps Lock or Escape remapping.
+- This session runs on Zeus, not Neogaia.
+
+## Design Tree
+
+- Restore Caps Lock behavior
+  - Scope the configuration
+    - Configure Neogaia only. ✓
+  - Select the mapping behavior.
+    - Restore `caps:escape_shifted_capslock`. ✓
+    - Set `services.xserver.xkb.options` in `configs/nixos/hosts/neogaia/default.nix`. ✓
+  - Define validation for Neogaia.
+    - Run static checks and manually verify both keys after deployment. ✓
+    - Stop after source and static validation. ✓
+
+## Settled Decisions
+
+1. Configure the mapping on Neogaia only.
+2. Restore `caps:escape_shifted_capslock`.
+3. Set `services.xserver.xkb.options` directly in Neogaia's host configuration.
+4. Run static checks and manually verify both keys on Neogaia after deployment.
+5. Stop after source and static validation.
+
+## Frontier
+
+None.

-# Deadnix Architecture
-
-## Purpose
-
-This note explains how `deadnix` finds unused Nix code.
-It focuses on architecture, not whether each check belongs in our linter.
-
-Use this note when deciding whether our linter needs scope analysis.
-
-## What Deadnix Is
-
-`deadnix` is a dead-code scanner for Nix.
-It finds bindings that introduce names which no live code uses.
-
-It is not a general style linter.
-It does not have many independent rules.
-It implements one analysis family: unused declarations.
-
-Like `statix`, it parses source text with `rnix`.
-It does not evaluate Nix.
-It does not import files.
-It reasons over local syntax and local scope only.
-
-## Minimal Dead-Code Vocabulary
-
-- A binding introduces a name.
-- A scope defines where introduced names are visible.
-- A use is an identifier occurrence that refers to a binding.
-- Shadowing happens when an inner scope reuses an outer name.
-- Dead code is a binding that no live code uses.
-- A fixed point is the final result after repeated analysis no longer changes.
-
-Dead-code analysis needs more state than a simple syntax lint.
-It must know which names a scope introduces and where those names can be used.
-
-## Component Map
-
-`deadnix` has fewer layers than `statix`.
-The command-line entry point, file walk, parsing, analysis, reporting, and editing live in one small tool.
-
-The important concepts are separate modules:
-
-- settings control analysis options;
-- scopes describe where names are introduced;
-- bindings describe individual declared names;
-- usage search answers whether a name appears in a live body;
-- dead-code results connect a binding to its scope;
-- reports render findings;
-- edits remove or rename unused declarations.
-
-## Main Pipeline
-
-```mermaid
-flowchart TD
-    A[Parse CLI options] --> B[Collect input files]
-    B --> C[Read each file]
-    C --> D[Parse with rnix]
-    D --> E[Skip file on parse errors]
-    D --> F[Run dead-code analysis]
-    F --> G[Print reports unless quiet]
-    G --> H[Apply edits when --edit is set]
-    H --> I[Exit 1 when --fail and findings exist]
-```
-
-The CLI accepts files or directories.
-Directory mode walks `.nix` files.
-Hidden files require an explicit option.
-Excludes filter paths before analysis.
-
-The tool skips dead-code diagnostics when a file has parse errors.
-It reports parse errors to the user and continues with other files.
-
-## Analysis Settings
-
-The analysis has four important switches.
-
-`no_lambda_arg` disables checks for single lambda arguments.
-This can avoid noise when an API requires an argument name.
-
-`no_lambda_pattern_names` disables checks for names in attribute-set function patterns.
-This matters for `callPackage`-style code, where argument names can be external API.
-
-`no_underscore` ignores bindings that start with `_`.
-This treats `_name` as an intentional unused placeholder.
-
-`warn_used_underscore` reports underscore-prefixed bindings that code actually uses.
-This enforces the convention that `_name` means unused.
-
-These settings are architecture-relevant because dead-code policy depends on API context.
-A repository linter needs a way to express that context.
-
-## Scope Model
-
-`deadnix` recognizes four scope types.
-
-### Lambda pattern scope
-
-A lambda pattern is a function argument written as an attribute set pattern.
-It can introduce field names and an optional alias for the whole argument set.
-
-Example shape:
-
-```nix
-args @ { pkgs, lib, ... }: body
-```
-
-This scope can introduce `args`, `pkgs`, and `lib`.
-
-### Lambda argument scope
-
-A single lambda argument introduces one name.
-
-Example shape:
-
-```nix
-pkgs: body
-```
-
-This scope introduces `pkgs`.
-
-### Let scope
-
-A `let` expression introduces bindings and inherited names.
-Those names are available in binding expressions and in the body.
-
-Example shape:
-
-```nix
-let
-  inherit (pkgs) hello;
-  value = hello;
-in
-  value
-```
-
-This scope introduces `hello` and `value`.
-
-### Recursive attribute-set scope
-
-A `rec` attribute set introduces names that sibling attributes can reference.
-`deadnix` models this scope, but treats its bindings as non-removable.
-
-That conservative choice avoids deleting public-looking attributes from recursive sets.
-
-## Binding Model
-
-A binding stores three facts.
-
-It stores the identifier name.
-It stores the syntax node that declared the name.
-It stores whether the binding is mortal.
-
-A mortal binding can become a dead-code finding.
-A non-mortal binding participates in name lookup but will not be removed.
-
-Single lambda arguments that already start with `_` are non-mortal.
-Recursive attribute-set bindings are also non-mortal.
-
-A binding also checks for the `deadnix: skip` pragma.
-The pragma applies to a nearby following declaration.
-The scanner searches backward from the declaration and stops after a blank-line boundary.
-
-## Usage Search
-
-Usage search asks whether a given name appears inside a syntax subtree.
-
-The search is scope-aware.
-When it enters a child scope that binds the same name, it stops following that branch.
-That prevents an inner binding from counting as a use of an outer binding.
-
-Attribute paths get special handling.
-Ordinary attribute keys do not count as uses.
-Dynamic or string attribute names can contain expressions, so the search looks inside those parts.
-
-`inherit` also gets special handling.
-A scope can inherit names from an outer scope.
-The analysis checks whether the inherited expression uses the searched name.
-
-## Fixed-Point Analysis
-
-`deadnix` repeats the scan until the result set stops changing.
-
-This matters because dead code can depend on other dead code.
-A binding can appear used during the first pass because another binding references it.
-If the referring binding is dead, the referenced binding is also dead.
-
-The loop tracks dead declaration nodes.
-During later scans, uses inside already-dead bodies do not keep other bindings alive.
-
-This fixed-point loop is the central architectural difference from simple local syntax lints.
-It makes dead-code results transitive.
-
-## Reporting Model
-
-A result stores the scope and binding for one finding.
-The display text combines both parts.
-Examples include unused lambda pattern, unused lambda argument, and unused let binding.
-
-Human output uses `ariadne`.
-The reporter groups ranges by line and labels the exact binding names.
-It uses different colors for different scope kinds.
-
-JSON output exists behind a feature flag.
-It emits file, message, line, column, and end column.
-
-`NO_COLOR` disables colored human output.
-
-## Edit Model
-
-`deadnix --edit` converts findings into text edits.
-Each edit has a start offset, end offset, and replacement string.
-
-The edit behavior depends on scope kind.
-
-For unused lambda pattern names, it removes the name and nearby comma or whitespace.
-For unused pattern aliases, it removes the alias syntax.
-For unused lambda arguments, it renames the argument with an underscore prefix.
-For unused `let` assignments, it deletes the assignment.
-For unused inherited names, it deletes only the inherited name.
-
-After those edits, it parses the edited source again.
-Then it removes empty `let in` constructs and empty `inherit` statements.
-
-This cleanup pass prevents the first edit batch from leaving invalid or useless scaffolding.
-
-## Error Handling
-
-If a path cannot be stated or read, the CLI reports the file error and continues.
-If a file has parse errors, the CLI reports those errors and skips dead-code analysis for that file.
-
-The `--fail` flag changes exit status when findings exist.
-Without `--fail`, findings do not make the command fail.
-
-This design separates report generation from CI policy.
-
-## Architectural Strengths
-
-The scope model is explicit.
-Each scope type declares which bindings it introduces and where those bindings are visible.
-
-The fixed-point loop catches transitive dead code.
-A binding used only by dead code also becomes dead.
-
-The usage search handles shadowing.
-That prevents common false positives in nested functions and nested `let` expressions.
-
-The edit model is tied to analysis results.
-It knows whether a binding came from a lambda, pattern, `let`, or `inherit`.
-
-The tool has few moving parts.
-That makes the analysis easy to follow compared to a general multi-rule linter.
-
-## Architectural Limits
-
-`deadnix` does not evaluate Nix.
-It cannot know which names external callers depend on.
-This matters for module arguments, package function arguments, and public attribute sets.
-
-It has global switches rather than project-specific rule contexts.
-For example, all lambda pattern names can be checked or skipped.
-The tool does not know that one directory contains `callPackage` functions.
-
-The analysis is local to one file.
-It cannot see that another file imports a function and relies on its argument names.
-
-The fixer performs text edits with byte ranges.
-It must handle punctuation and whitespace carefully.
-Pattern edits are harder than simple assignment deletion.
-
-The tool has one analysis family.
-It is not a framework for many unrelated rules.
-
-## Lessons for Our Linter
-
-Dead-code checks need a scope pass.
-A per-node rule interface is not enough when a diagnostic depends on name visibility.
-
-Represent scopes explicitly.
-Each scope type should provide introduced bindings and visible bodies.
-
-Track shadowing before reporting unused names.
-A text search for an identifier is not sufficient.
-
-Use fixed-point analysis for transitive dead code.
-One pass misses names used only by dead declarations.
-
-Separate policy from mechanics.
-The mechanics can find unused names.
-Repository policy decides whether module arguments, package arguments, or underscore names count.
-
-Treat autofix as scope-specific.
-Removing a pattern name is not the same operation as deleting a `let` assignment.
-
-Run cleanup after edits.
-Dead-code fixes can create empty `let` expressions and empty `inherit` statements.
-
-## Open Design Questions for Our Linter
-
-- Should dead-code analysis be part of `nix-style-linter`, or a separate command?
-- Should policy vary by path, file kind, or suppression comment?
-- Should recursive attribute-set members ever become removable findings?
-- Should underscore names mean ignored, or should used underscore names be errors?
-- Should the linter report unused names without offering autofix first?
-- Should cleanup rules run as ordinary rules or as a post-fix pass?

-# Hyprland Lua Migration Plan
-
-## Problem Statement
-
-The Hyprland compositor config uses Home Manager's hyprlang output.
-Hyprland deprecates hyprlang for the main compositor config.
-The repository needs to generate a Lua config without changing desktop behavior.
-
-## Solution
-
-Keep the config owned by Nix and Home Manager.
-Switch the Hyprland Home Manager config output to Lua.
-Convert only the settings whose shape changes under Lua.
-
-This is not a desktop redesign.
-The change preserves the current monitors, binds, window rules, environment variables, and UWSM startup.

-1. As the operator, I want Hyprland to load `hyprland.lua`, so that startup no longer warns about hyprlang deprecation.
-
-2. As the operator, I want existing keyboard binds to keep working, so that the desktop behavior stays unchanged.
-
-3. As the operator, I want host monitor layout to stay unchanged, so that the physical display setup does not move.
-
-4. As the operator, I want session environment variables to stay in the compositor config, so that Wayland and cursor behavior stays unchanged.
-
-5. As the operator, I want auxiliary module binds to keep working, so that launcher, lock, screenshot, clipboard, notifications, and recording flows stay usable.
-
-## Implementation Decisions
-
-1. Use Home Manager's Lua config generator.
-   Set the Hyprland config type to Lua and keep package ownership unchanged.
-
-2. Keep ordinary compositor options declarative in Nix.
-   Move input, general, decoration, xwayland, animation, and layout settings into the Lua config structure.
-
-3. Remove hyprlang-only variables from generated config.
-   Keep modifier and terminal values as Nix locals or helper inputs.
-
-4. Add minimal local helpers for Lua calls.
-   Use helpers only for repeated bind, dispatcher, command, environment, and rule shapes.
-
-5. Convert all bind strings to Lua bind call data.
-   Preserve key combinations, dispatchers, commands, repeat behavior, and locked-session behavior.
-
-6. Convert contributed binds in their owning modules.
-   Keep each bind near the module that owns the tool it launches.
-
-7. Convert monitor strings to Lua monitor records.
-   Preserve output names, modes, positions, scale values, and rotation.
-
-8. Convert the screenshot window rule to the Lua rule shape.
-   Preserve the Satty class matcher and floating behavior.
-
-9. Convert environment strings to Lua environment calls.
-   Preserve the Wayland flag and cursor variables.
-
-10. Delete or update comments that describe hyprlang syntax.
-    Keep comments that explain behavior or non-obvious invariants.
-
-## Testing Decisions
-
-1. Run the repository Nix formatting and style checks for modified Nix files.
-
-2. Evaluate or build the affected host configuration.
-   This proves Home Manager accepts the Lua settings structure.
-
-3. Confirm the generated config file uses Lua.
-   The expected output is `hyprland.lua`, not `hyprland.conf`.
-
-4. Verify Hyprland accepts the generated Lua config.
-   Use Hyprland config verification when the installed build supports it.
-   Otherwise reload the compositor and inspect errors.
-
-5. Smoke test the changed desktop surface.
-   Test one bind from each source area after reload.
-
-6. Check the explicit monitor layout on the host that declares it.
-   Confirm resolution, position, scale, and rotation stayed unchanged.
-
-## Out of Scope
-
-- Do not split the config into Lua modules.
-- Do not hand-write a full Lua config.
-- Do not add new Hyprland behavior.
-- Do not change UWSM startup.
-- Do not redesign binds, monitor layout, or visual settings.
-- Do not change hyprlock, hypridle, waybar, mako, or rofi settings beyond their Hyprland binds.
-
-## Further Notes
-
-Home Manager documents `configType = "lua"` for Hyprland.
-It maps settings to `hl.*` calls.
-It supports `_args` for multi-argument calls.
-It supports raw Lua expressions with `lib.generators.mkLuaInline`.
-
-The riskiest parts are binds, monitor declarations, and window rules.
-Those parts changed shape more than scalar config sections.
-
-Assumption: the pinned Home Manager input contains the documented Lua Hyprland generator.
-Validate this during the configuration build.

+# NixOS AGENTS and style-skill scope design tree
+
+This tree reviews `configs/nixos/AGENTS.md`.
+It decides which instructions belong in Nix style rules.
+
+## Known facts
+
+- `configs/nixos/AGENTS.md` has 70 lines.
+- Each frontier question quotes the complete instruction under review.
+- This review decides instruction placement only.
+- It supplies guidance for desktop, Firefox, Neovim, AI tooling, and NixOS gotchas.
+- The `/review` prompt loads `nix-style` for Nix files.
+- `nix-style` loads every rule under `src/skills/style/nix/rules/`.
+- The current Nix rules cover Nix syntax and flake structure.
+- `configs/nixos/AGENTS.md` includes a guest-module ownership rule.
+- The RomM session missed that ownership rule during implementation.
+- `registry.window-icon` exists in `configs/nixos/registry/window-icon.nix`.
+- Desktop application modules declare window classes and rendered icons in that registry.
+- Hyprland reads the registry to generate workspace icon mappings.
+- The AGENTS instruction named the registry after its introduction on 2026-10-11.
+- The `class` option describes its window-class match.
+- The `icon` option describes a string icon value.
+- The registry schema does not document the rendered-string requirement or the class-discovery command.
+- Hyprland renders `config.registry.env` as its `env` configuration.
+- The `env` registry replaced direct Hyprland environment declarations in commit `370cab8f8`.
+- `configs/nixos/modules/desktop/apps/r2modman.nix` enables a graphical application without a `registry.window-icon` declaration.
+- The current registry modules already validate value uniqueness and field combinations.
+- They do not validate required producer declarations.
+- The registry collector is specific to the NixOS dotfiles configuration.
+- A non-discoverable environment fact records local behavior that configuration, source code, and normal tool help do not reveal.
+- The current instruction groups are:
+  - Desktop: window icons, Hyprland environment variables, and cursor settings.
+  - Firefox: search-engine declarations and extension-storage compatibility.
+  - Neovim: Nixvim package-set selection.
+  - AI tooling: Herdr key names and Pi configuration locations.
+  - Gotchas: registry APIs, guest boundaries, SOPS ownership, guest mounts, deployment, DNS, hardware, module paths, and host commands.
+
+## Decision tree
+
+- Instruction review
+  - Settled: Review each complete instruction in source order.
+  - Registry conventions
+    - Settled: Create `src/skills/style/nix/rules/dotfiles.md`.
+    - Graphical application icon instruction
+      - Settled: Move the complete instruction to `src/skills/style/nix/rules/dotfiles.md`.
+    - Hyprland session environment instruction
+      - Settled: Remove it because `registry.env` superseded it.
+    - Firefox search-engine instruction
+      - Settled: Remove it because the Firefox module documents the configuration.
+    - Firefox extension-storage instruction
+      - Settled: Move it to a comment above `extensions.settings` in `modules/desktop/apps/firefox.nix`.
+    - Neovim package-set instruction
+      - Settled: Move it to a comment above `nixpkgs.useGlobalPackages` in `modules/shell/nvim/default.nix`.
+    - Herdr key-name instruction
+      - Settled: Remove it.
+    - Pi extension location instruction
+      - Settled: Remove it. It recorded a completed migration from NixOS-managed sources.
+    - Pi generated-settings instruction
+      - Settled: Remove it because the Pi module documents the managed boundary.
+    - Library-function qualification instruction
+      - Settled: Generalize it and move it to `src/skills/style/nix/rules/general.md`.
+    - Guest ownership instruction
+      - Settled: Move it to `src/skills/style/nix/rules/dotfiles.md`.
+    - SOPS guest-owner instruction
+      - Settled: Move it to `src/skills/style/nix/rules/dotfiles.md`.
+    - Nested guest-mount instruction
+      - Settled: Remove it because the example describes no active layout.
+    - `deploy-to` instruction
+      - Settled: Remove it. Agents cannot complete its remote sudo steps.
+    - Pikachu deploy-closure instruction
+      - Settled: Remove it because `deploy-to` encodes the required import path.
+    - Public-DNS instruction
+      - Settled: Remove it.
+    - Hardware-configuration instruction
+      - Settled: Remove it because the root auto-generated-file rule owns the policy.
+    - Chaotic-cache instruction
+      - Settled: Remove it because `modules.host.cachyos.enable` owns the cache configuration.
+    - Module-relative-path instruction
+      - Settled: Remove it because Nix evaluation reports invalid paths.
+    - Pikachu `uptime` instruction
+      - Settled: Remove it because the command exposes its supported options.
+    - Guest-ACME-evaluation instruction
+      - Settled: Remove it because current direct guest evaluation succeeds.
+    - systemd executable instruction
+      - Settled: Remove it because `general.md` already requires `lib.getExe'` for non-main executables.
+
+## Frontier
+
+The frontier is empty.
+
+## Shared understanding
+
+Remove these instructions from `configs/nixos/AGENTS.md`:
+
+- Hyprland session environment
+- Firefox search engines
+- Herdr shifted punctuation
+- Pi extension source location
+- Pi managed settings
+- Nested guest mounts
+- `deploy-to` behavior
+- Pikachu deploy closures
+- Public DNS boundary
+- Hardware configuration
+- Chaotic cache selection
+- Module-relative paths
+- Pikachu boot time
+- Guest ACME evaluation
+- systemd executable selection
+
+Move these instructions intact to `src/skills/style/nix/rules/dotfiles.md`:
+
+- Graphical application icons
+- Guest ownership
+- SOPS guest ownership
+
+Move the generalized library-function qualification convention to
+`src/skills/style/nix/rules/general.md`.
+
+Move these instructions to code comments:
+
+- Firefox extension storage: above `extensions.settings` in
+  `configs/nixos/modules/desktop/apps/firefox.nix`
+- Nixvim package set: above `nixpkgs.useGlobalPackages` in
+  `configs/nixos/modules/shell/nvim/default.nix`
+
+The review does not decide how to restore the auto-generated status of
+`configs/nixos/hosts/pikachu/hardware-configuration.nix`.
+
+The operator confirmed this design and authorized the edits.

+# RomM migration design tree
+
+## Known facts
+
+- RomM is listed under the Pikachu and Pichu Proxmox migration.
+- Pikachu already runs VLAN 20 guests with persistent storage.
+- Nixpkgs provides a tested `services.romm` module at version 5.2.0.
+- `services.romm.dataDir` defaults to `/var/lib/romm`.
+- RomM stores the game library below `/var/lib/romm/library`.
+- RomM stores saves, states, user-uploaded screenshots, and profile avatars below `/var/lib/romm/assets/users/<user-id>/`.
+- RomM derives `<user-id>` from its database ID, so it is not a stable configured username.
+- RomM stores scraped covers and provider-sourced game screenshots below `/var/lib/romm/resources/roms/<platform-id>/<rom-id>/`.
+- RomM 5.4.0 exists upstream but Nixpkgs does not package it.
+- RomM 5.3.0 requires an explicit library-structure declaration in `config.yml`.
+- The 5.4.0 package phase must add the Structure A declaration for `roms/{platform}/{game}` and `bios/{platform}`.
+- RomM 5.4.0 can modify ROM files in place only when library conversion is explicitly enabled.
+- RomM 5.3.0 identifies hashed ROMs by CRC, MD5, and SHA-1 after a scan.
+- RomM 5.3.0 matches moved or renamed hashed ROMs to their existing database records.
+- This migration is a fresh installation.
+- The new library will receive selected ROMs from the old installation.
+- Copyparty serves `/pikachu/media` as its writable `/media` volume.
+
+## Decision tree
+
+- RomM deployment
+  - Target location
+    - Settled: Deploy a dedicated guest on Pikachu.
+    - Package source
+      - Settled: Start with Nixpkgs's RomM 5.2.0 package.
+      - Settled: Package RomM 5.4.0 locally as follow-up work.
+    - Persistent storage
+      - Settled: Use `/var/lib/romm` in the guest.
+      - Settled: Mount `/pikachu/data/romm` at `/var/lib/romm`.
+      - Settled: Mount the ROM library separately at `/var/lib/romm/library`.
+      - Settled: Mount user assets separately for Copyparty browsing.
+      - Settled: Keep scraped resources in `/pikachu/data/romm`.
+      - Settled: Mount `/pikachu/media/games/emulation/roms` at `/var/lib/romm/library/roms`.
+      - Settled: Mount `/pikachu/media/games/emulation/bios` at `/var/lib/romm/library/bios`.
+      - Settled: Mount `/pikachu/media/games/emulation/users` at `/var/lib/romm/assets/users`.
+      - Settled: Mount `/pikachu/data/romm/postgresql` at `/var/lib/postgresql`.
+      - Settled: Mount `/pikachu/data/romm/redis` at `/var/lib/redis-romm`.
+    - Guest networking
+      - Settled: Follow the standard guest-provisioning protocol, including its VLAN 20 DHCP reservation.
+    - Public route
+      - Settled: Retain the old installation's public domain.
+    - Metadata and authentication secrets
+      - Settled: Configure IGDB, ScreenScraper, and SteamGridDB.
+      - Settled: Use RomM's default metadata and artwork priority.
+      - Settled: Manage the 5.4.0 `config.yml` declaratively with Nix.
+      - Settled: Use RomM's default region and English-language priority.
+    - Save synchronization
+      - Settled: Disable automatic browser save synchronization in 5.4.0.
+    - Authentication
+      - Settled: Use RomM's built-in accounts initially.
+      - Deferred: Configure RomM as an OpenID Connect client after an identity provider exists.
+    - ROM selection and import
+      - Settled: The operator manually selects and copies ROMs after deployment.
+      - Settled: Do not create automatic import tooling or a ROM manifest.
+    - Capacity and service limits
+      - Settled: Limit the guest to `4G` memory, `200%` CPU, and `512` tasks.
+    - Library scanning
+      - Settled: Enable the filesystem watcher for library changes.
+    - Cutover and retirement
+      - Out of scope: The operator manages the old installation and public-domain cutover outside this monorepo.
+  - Work phases
+    - Settled: Create a RomM guest module with Nixpkgs's package in [[0014-romm-guest]].
+    - Settled: Package RomM 5.4.0 locally and reuse `services.romm` in [[0015-romm-5-4-package]].
+    - Settled: Move selected ROMs after the service deployment is ready in [[0016-romm-manual-rom-migration]].
+
+## Settled decisions
+
+- **Migration model:** Start with a fresh RomM installation.
+- **Data scope:** Copy selected ROMs from the old installation.
+- **Old application state:** Do not migrate the database, users, sessions, or job queue.
+- **Deployment target:** Deploy a dedicated guest on Pikachu.
+- **Initial package:** Use Nixpkgs's RomM 5.2.0 package.
+- **Package follow-up:** Package RomM 5.4.0 locally.
+- **Work phases:** Deploy the guest, update the package, then import selected ROMs.
+- **Guest data directory:** Use RomM's default `/var/lib/romm`.
+- **Host application data:** Mount `/pikachu/data/romm` at `/var/lib/romm`.
+- **ROM library:** Mount it separately at `/var/lib/romm/library`.
+- **Storage classification:** Preserve the distinction between application data and browsable media.
+- **User assets:** Mount `/pikachu/media/games/emulation/users` at `/var/lib/romm/assets/users` to expose saves, states, user-uploaded screenshots, and profile avatars through Copyparty.
+- **ROM paths:** Mount `/pikachu/media/games/emulation/roms` and `/pikachu/media/games/emulation/bios` at the corresponding children of `/var/lib/romm/library`.
+- **Guest networking:** Follow the standard guest-provisioning protocol.
+- **Public route:** Retain the old installation's public domain.
+- **Metadata providers:** Configure IGDB, ScreenScraper, and SteamGridDB in both package phases.
+- **Metadata priority:** Use RomM's default metadata and artwork priority.
+- **RomM configuration:** Manage the required 5.4.0 `config.yml` declaratively with Nix.
+- **Scan region and language priority:** Use RomM's defaults.
+- **Initial authentication:** Use RomM's built-in accounts.
+- **OIDC follow-up:** Track it in [[0013-oidc-provider]].
+- **ROM migration:** The operator manually selects and copies ROMs after deployment.
+- **Guest limits:** Cap the guest at `4G` memory, `200%` CPU, and `512` tasks.
+- **Library watcher:** Enable the filesystem watcher.
+- **PostgreSQL:** Mount `/pikachu/data/romm/postgresql` at `/var/lib/postgresql`.
+- **Redis:** Mount `/pikachu/data/romm/redis` at `/var/lib/redis-romm`.
+- **Browser save synchronization:** Disable it in 5.4.0 until browser emulation is needed.

+# Whisper dictation
+
+Provide reliable local dictation on Zeus.
+
+## Prototype findings
+
+- `hyprwhspr-rs` provides PipeWire capture, local `whisper.cpp` transcription, clipboard copying, and Hyprland integration.
+- The prototype used `small.en` from `~/dwn/ggml-small.en.bin`.
+- The initial CPU prototype transcribed accurately but added about 2.3 seconds after a 2.9-second recording.
+- Vulkan acceleration uses `whisper-cpp-vulkan` and `gpu_layers = 999`.
+- `SUPER + ALT + D` starts recording on press and stops recording on release.
+- Hyprland Lua represents release bindings with `hl.bind(..., { release = true })`.
+- `hyprwhspr-rs` uses Hyprland's removed `sendshortcut` dispatcher for automatic paste.
+- Its virtual-keyboard fallback can drop modifiers and insert only `v`.
+- Treat the prototype configuration as disposable because it no longer works reliably.
+
+## Completion
+
+- [ ] Choose a maintained local speech-to-text backend.
+- [ ] Record microphone audio through PipeWire.
+- [ ] Transcribe locally with GPU acceleration when available.
+- [ ] Insert transcribed text reliably into the focused application.
+- [ ] Copy transcribed text to the clipboard.
+- [ ] Test dictation with representative technical speech.

+
+A CLI tool that basically works as a strict allowlist for words used in prose such as markdown files or strings passed to the tool.
+
+The basic idea can be found in [[dictionary]], but as it would be a deterministic tool, a strict allowlist might be more beneficial.

+
+One of the biggest patterns I noticed when working on Rust projects in the monorepo was that they were mostly CLI tools. I found myself doing the same boilerplate over and over again.
+
+I think much like Google, having a function that handles sensible defaults would be a good idea.
+
+But also, maybe a Rust project set up to avoid the common pitfalls?

+1. Randomizing the desktop wallpaper from a select list.
+2. A web service endpoint that provides a random image from a configured directory/set.
+
+The first idea might not need any special code, so it wouldn't be a CLI.
+
+I think that any tools I write should have both a non-interactive mode and a TUI or web server mode.

-# Conventional Commits 1.0.0
-
-## Summary
-
-The Conventional Commits specification is a lightweight convention on top of commit messages.
-It provides an easy set of rules for creating an explicit commit history;
-which makes it easier to write automated tools on top of.
-This convention dovetails with [SemVer](http://semver.org),
-by describing the features, fixes, and breaking changes made in commit messages.
-
-The commit message should be structured as follows:
-
----
-
-```
-<type>[optional scope]: <description>
-
-[optional body]
-
-[optional footer(s)]
-```
-
----
-
-The commit contains the following structural elements, to communicate intent to the
-consumers of your library:
-
-1. **fix:** a commit of the _type_ `fix` patches a bug in your codebase (this correlates with [`PATCH`](http://semver.org/#summary) in Semantic Versioning).
-2. **feat:** a commit of the _type_ `feat` introduces a new feature to the codebase (this correlates with [`MINOR`](http://semver.org/#summary) in Semantic Versioning).
-3. **BREAKING CHANGE:** a commit that has a footer `BREAKING CHANGE:`, or appends a `!` after the type/scope, introduces a breaking API change (correlating with [`MAJOR`](http://semver.org/#summary) in Semantic Versioning).
-A BREAKING CHANGE can be part of commits of any _type_.
-4. _types_ other than `fix:` and `feat:` are allowed, for example [@commitlint/config-conventional](https://github.com/conventional-changelog/commitlint/tree/master/%40commitlint/config-conventional) (based on the [Angular convention](https://github.com/angular/angular/blob/22b96b9/CONTRIBUTING.md#type)) recommends `build:`, `chore:`,
-   `ci:`, `docs:`, `style:`, `refactor:`, `perf:`, `test:`, and others.
-5. _footers_ other than `BREAKING CHANGE: <description>` may be provided and follow a convention similar to
-   [git trailer format](https://git-scm.com/docs/git-interpret-trailers).
-
-Additional types are not mandated by the Conventional Commits specification, and have no implicit effect in Semantic Versioning (unless they include a BREAKING CHANGE).
-A scope may be provided to a commit’s type, to provide additional contextual information and is contained within parenthesis, e.g., `feat(parser): add ability to parse arrays`.
-
-## Examples
-
-### Commit message with description and breaking change footer
-
-```
-feat: allow provided config object to extend other configs
-
-BREAKING CHANGE: `extends` key in config file is now used for extending other config files
-```
-
-### Commit message with `!` to draw attention to breaking change
-
-```
-feat!: send an email to the customer when a product is shipped
-```
-
-### Commit message with scope and `!` to draw attention to breaking change
-
-```
-feat(api)!: send an email to the customer when a product is shipped
-```
-
-### Commit message with both `!` and BREAKING CHANGE footer
-
-```
-chore!: drop support for Node 6
-
-BREAKING CHANGE: use JavaScript features not available in Node 6.
-```
-
-### Commit message with no body
-
-```
-docs: correct spelling of CHANGELOG
-```
-
-### Commit message with scope
-
-```
-feat(lang): add Polish language
-```
-
-### Commit message with multi-paragraph body and multiple footers
-
-```
-fix: prevent racing of requests
-
-Introduce a request id and a reference to latest request. Dismiss
-incoming responses other than from latest request.
-
-Remove timeouts which were used to mitigate the racing issue but are
-obsolete now.
-
-Reviewed-by: Z
-Refs: #123
-```
-
-## Specification
-
-The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC 2119](https://www.ietf.org/rfc/rfc2119.txt).
-
-1. Commits MUST be prefixed with a type, which consists of a noun, `feat`, `fix`, etc.,
-   followed by the OPTIONAL scope, OPTIONAL `!`, and REQUIRED terminal colon and space.
-2. The type `feat` MUST be used when a commit adds a new feature to your application or library.
-3. The type `fix` MUST be used when a commit represents a bug fix for your application.
-4. A scope MAY be provided after a type.
-A scope MUST consist of a noun describing a section of the codebase surrounded by parenthesis, e.g., `fix(parser):`
-5. A description MUST immediately follow the colon and space after the type/scope prefix.
-The description is a short summary of the code changes, e.g., _fix: array parsing issue when multiple spaces were contained in string_.
-6. A longer commit body MAY be provided after the short description, providing additional contextual information about the code changes.
-The body MUST begin one blank line after the description.
-7. A commit body is free-form and MAY consist of any number of newline separated paragraphs.
-8. One or more footers MAY be provided one blank line after the body.
-Each footer MUST consist of a word token, followed by either a `:<space>` or `<space>#` separator, followed by a string value (this is inspired by the [git trailer convention](https://git-scm.com/docs/git-interpret-trailers)).
-9. A footer’s token MUST use `-` in place of whitespace characters, e.g., `Acked-by` (this helps differentiate the footer section from a multi-paragraph body).
-An exception is made for `BREAKING CHANGE`, which MAY also be used as a token.
-10. A footer’s value MAY contain spaces and newlines, and parsing MUST terminate when the next valid footer token/separator pair is observed.
-11. Breaking changes MUST be indicated in the type/scope prefix of a commit, or as an entry in the footer.
-12. If included as a footer, a breaking change MUST consist of the uppercase text BREAKING CHANGE, followed by a colon, space, and description, e.g., _BREAKING CHANGE: environment variables now take precedence over config files_.
-13. If included in the type/scope prefix, breaking changes MUST be indicated by a `!` immediately before the `:`.
-If `!` is used, `BREAKING CHANGE:` MAY be omitted from the footer section, and the commit description SHALL be used to describe the breaking change.
-14. Types other than `feat` and `fix` MAY be used in your commit messages, e.g., _docs: updated ref docs._
-15. The units of information that make up Conventional Commits MUST NOT be treated as case sensitive by implementors, with the exception of BREAKING CHANGE which MUST be uppercase.
-16. BREAKING-CHANGE MUST be synonymous with BREAKING CHANGE, when used as a token in a footer.
-
-## FAQ
-
-### How does Conventional Commits handle revert commits?
-
-Reverting code can be complicated: are you reverting multiple commits?
-if you are reverting a feature, should the next release instead be a patch?
-
-Conventional Commits does not make an explicit effort to define revert behavior.
-Instead we leave it to tooling authors to use the flexibility of _types_ and _footers_ to develop their logic for handling reverts.
-
-One recommendation is to use the `revert` type, and a footer that references the commit SHAs that are being reverted:
-
-```
-revert: let us never again speak of the noodle incident
