-# k-launcher Architecture
-
-## Philosophy
-
-- **TDD:** Red-Green-Refactor is mandatory. No functional code without a failing test first.
-- **Clean Architecture:** Strict layer separation — Domain, Application, Infrastructure, Main.
-- **Newtype Pattern:** All domain primitives wrapped (e.g. `struct Score(f64)`).
-- **Small Traits / ISP:** Many focused traits over one "God" trait.
-- **No Cyclic Dependencies:** Use IoC (define traits in higher-level modules, implement in lower-level).

-## Workspace Structure
-
-| Crate | Layer | Responsibility |
-|---|---|---|
-| `k-launcher-kernel` | Domain + Application | Newtypes (`ResultId`, `ResultTitle`, `Score`), `Plugin` trait, `SearchEngine` trait, `AppLauncher` port, `Kernel` use case |
-| `k-launcher-config` | Infrastructure | TOML config loading; `Config`, `WindowCfg`, `AppearanceCfg`, `PluginsCfg` structs |
-| `k-launcher-os-bridge` | Infrastructure | `UnixAppLauncher` (process spawning), `WindowConfig` adapter |
-| `k-launcher-plugin-host` | Infrastructure | `ExternalPlugin` — JSON-newline IPC protocol for out-of-process plugins |
-| `k-launcher-ui` | Infrastructure | iced 0.14 Elm-like UI (`KLauncherApp`, debounced async search, keyboard nav) |
-| `k-launcher-ui-egui` | Infrastructure | Alternative egui UI (feature-gated) |
-| `plugins/plugin-apps` | Infrastructure | XDG `.desktop` parser, frecency scoring, nucleo fuzzy matching |
-| `plugins/plugin-calc` | Infrastructure | `evalexpr`-based calculator |
-| `plugins/plugin-cmd` | Infrastructure | Shell command runner |
-| `plugins/plugin-files` | Infrastructure | File path search |
-| `plugins/plugin-url` | Infrastructure | URL opener |
-| `k-launcher` | Main/Entry | DI wiring, CLI arg parsing (`show` command), `run_ui()` composition root |

-
-All arrows point inward toward the kernel. The kernel has no external dependencies.
-
----
-
-## Core Abstractions (kernel)
-
-```rust
-// Plugin trait — implemented by every plugin
-async fn search(&self, query: &str) -> Vec<SearchResult>;
-
-// SearchEngine trait — implemented by Kernel
-async fn search(&self, query: &str) -> Vec<SearchResult>;
-
-// AppLauncher port — implemented by UnixAppLauncher in os-bridge
-fn execute(&self, action: &LaunchAction);
-
-// DesktopEntrySource trait (plugin-apps) — swappable .desktop file source
-```
-
----
-
-## Plugin System
-
-Two kinds of plugins:
-
-1. **In-process** — implement `Plugin` in Rust, linked at compile time.
-   - `plugin-calc`, `plugin-apps`, `plugin-cmd`, `plugin-files`, `plugin-url`
-
-2. **External / out-of-process** — `ExternalPlugin` in `k-launcher-plugin-host` communicates via JSON newline protocol over stdin/stdout.
-   - Query: `{"query": "..."}`
-   - Response: `[{"id": "...", "title": "...", "score": 1.0, "description": "...", "icon": "...", "action": "..."}]`
-
-Plugins are enabled/disabled via `~/.config/k-launcher/config.toml`.
-
----
-
-## Kernel (Application Use Case)
-
-`Kernel::search` fans out to all registered plugins concurrently via `join_all`, merges results, sorts by `Score` descending, truncates to `max_results`.
-
----
-
-## UI Architecture (iced 0.14 — Elm model)
-
-- **State:** `KLauncherApp` holds engine ref, launcher ref, query string, results, selected index, appearance config.
-- **Messages:** `QueryChanged`, `ResultsReady`, `KeyPressed`
-- **Update:**
-  - `QueryChanged` → spawns debounced async task (50 ms) → `ResultsReady`
-  - Epoch guard prevents stale results from out-of-order responses
-- **View:** search bar + scrollable result list with icon support (SVG/raster)
-- **Subscription:** keyboard events — `Esc` = quit, `Enter` = launch, arrows = navigate
-- **Window:** transparent, undecorated, centered (Wayland-compatible)
-
----
-
-## Frecency (plugin-apps)
-
-`FrecencyStore` records app launches by ID. On empty query, returns top-5 frecent apps instead of search results.
-
----
-
-## Configuration
-
-`~/.config/k-launcher/config.toml` — sections: `[window]`, `[appearance]`, `[search]`, `[plugins]`.
-
-All fields have sane defaults; a missing file yields defaults without error.

-## 1. Core Philosophy
-
-- **Test-Driven Development (TDD):** No functional code is written without a failing test first. Red-Green-Refactor is the mandatory cycle.
-- **Clean Architecture:** Maintain strict separation between Domain, Application, and Infrastructure layers.
-- **Newtype Pattern:** Use the "Newtype" pattern for all domain primitives (e.g., `struct UserId(Uuid)`) to ensure type safety and prevent primitive obsession.
-
----
-
-## 2. Structural Rules
-
-### Dependency Management
-
-- **Strict Unidirectionality:** Dependencies must only point inwards (towards the Domain).
-- **No Cyclic Dependencies:** Use traits and Dependency Injection (DI) to break cycles. If two modules need each other, abstract the shared behavior into a trait or move common data to a lower-level module.
-- **Feature Gating:** Organize the project into logical crates or modules that can be compiled independently.
-
-### Traits and Decoupling
-
-- **Swappable Infrastructure:** Define all external interactions (Database, API, File System) as traits in the Application layer.
-- **Small Traits:** Adhere to the Interface Segregation Principle. Favor many specific traits over one "God" trait.
-- **Mocking:** Use traits to allow easy mocking in unit tests without requiring a real database or network.
-
----
-
-## 3. Rust Specifics & Clean Code
-
-### Type Safety
-
-- Avoid `String` or `i32` for domain concepts. Wrap them in structs.
-- Use `Result` and `Option` explicitly. Minimize `unwrap()` and `expect()`—handle errors gracefully at the boundaries.
-
-### Formatting & Style
-
-- Follow standard `rustfmt` and `clippy` suggestions.
-- Function names should be descriptive (e.g., `process_valid_order` instead of `handle_data`).
-- Keep functions small (typically under 20-30 lines).
-
----
-
-## 4. Layer Definitions
-
-| Layer              | Responsibility                                | Allowed Dependencies |
-| ------------------ | --------------------------------------------- | -------------------- |
-| **Domain**         | Pure Business Logic, Entities, Value Objects. | None (Pure Rust)     |
-| **Application**    | Use Cases, Orchestration, Trait definitions.  | Domain               |
-| **Infrastructure** | Trait implementations (DB, HTTP clients).     | Domain, Application  |
-| **Main/API**       | Entry point, Wire-up/DI, Routing.             | All of the above     |
-
----
-
-## 5. TDD Workflow Requirement
-
-1. **Write a Test:** Create a test in `src/lib.rs` or a `tests/` directory.
-2. **Define the Interface:** Use a trait or function signature to make the test compile (but fail).
-3. **Minimum Implementation:** Write just enough code to pass the test.
-4. **Refactor:** Clean up the logic, ensure no duplication, and check for "Newtype" opportunities.
-
-> **Note on Cyclic Dependencies:** If an AI agent suggests a change that introduces a cycle, it must be rejected. Use **Inversion of Control** by defining a trait in the higher-level module that the lower-level module implements.
