release: v1.14.0

## Summary

- `get_global_claude_md` and `save_global_claude_md` were using `dirs::home_dir()` which resolves to the Windows home directory (`C:\Users\accou`) on Windows builds
- The actual `~/.claude/CLAUDE.md` lives in the WSL home directory, so the editor was always showing an empty text box and would have written to the wrong location on save
- Added `get_global_claude_md_via_wsl()` and `save_global_claude_md_via_wsl()` helpers that shell out to WSL (matching the existing pattern used by `list_skills` and `list_memory_files`)
- Both Tauri commands now branch on `cfg!(target_os = "windows")` to use the appropriate path

## Test plan

- [ ] Open Settings sidebar on a Windows build — Global Instructions textarea should load the contents of `~/.claude/CLAUDE.md` from WSL
- [ ] Edit the content and click Save — verify the WSL file is updated
- [ ] Verify Linux/macOS builds are unaffected (native filesystem path unchanged)

+```
+
+Example push command:
+
+```bash
+git push https://hikari:TOKEN@git.nhcarrigan.com/nhcarrigan/hikari-desktop.git <branch>
+```
+
+## Testing Requirements
+
+**All changes MUST include tests.** This is non-negotiable — no feature, bug fix, or refactor should be committed without corresponding test coverage. If a change cannot be tested (e.g. pure UI layout, Tauri IPC calls that are impossible to mock), document why in a comment.
+
+- **Frontend tests**: Use Vitest with `@testing-library/svelte` for component tests
+- **Test files**: Place test files next to the code they test with `.test.ts` or `.spec.ts` extension
+- **Run tests**: Use `pnpm test` to run all tests, or `pnpm test:watch` for watch mode
+- **Coverage**: Run `pnpm test:coverage` to generate coverage reports
+- **Rust tests**: Use `pnpm test:backend` for Rust/Tauri backend tests
+
+### Testing Guidelines
+
+- Write tests for utility functions, stores, and business logic
+- For Svelte 5 components, focus on testing the underlying logic functions
+- Use descriptive test names that explain what behaviour is being tested
+- Include edge cases and error conditions in test coverage
+- Mock Tauri APIs using the patterns in `vitest.setup.ts`
+- **Coverage Goal**: Maintain as close to 100% test coverage as possible across the entire codebase
+
+### Mocking Strategies
+
+#### Console Mocking
+
+When testing code that intentionally logs errors (like error handling paths), mock console methods to prevent stderr output that makes tests appear flaky:
+
+```typescript
+it("handles errors gracefully", async () => {
+  const consoleErrorSpy = vi.spyOn(console, "error").mockImplementation(() => {});
+
+  // Test error handling code
+  await expect(functionThatLogs()).rejects.toThrow();
+
+  // Verify error was logged
+  expect(consoleErrorSpy).toHaveBeenCalledWith("Expected error:", expect.any(Error));
+
+  // Restore console.error
+  consoleErrorSpy.mockRestore();
+});
+```
+
+#### E2E Integration Testing for Cross-Platform Code
+
+For code that calls platform-specific system APIs (like Windows PowerShell or Linux notify-send), use helper functions that build the command structure without execution. This allows CI to verify cross-platform compatibility on Linux-only containers:
+
+```rust
+/// Build notify-send command for testing (doesn't execute)
+#[cfg(test)]
+fn build_notify_send_command(title: &str, body: &str) -> (String, Vec<String>) {
+    (
+        "notify-send".to_string(),
+        vec![
+            title.to_string(),
+            body.to_string(),
+            "--urgency=normal".to_string(),
+            "--app-name=Hikari Desktop".to_string(),
+        ],
+    )
+}
+
+#[test]
+fn test_e2e_notify_send_command_structure() {
+    let (command, args) = build_notify_send_command("Test Title", "Test Body");
+
+    assert_eq!(command, "notify-send");
+    assert_eq!(args.len(), 4);
+    assert_eq!(args[0], "Test Title");
+    assert_eq!(args[1], "Test Body");
+}
+```
+
+This approach:
+
+- Verifies command structure, argument order, and escaping logic
+- Tests cross-platform code paths without requiring the target platform
+- Allows CI to catch regressions in Windows-specific code whilst running on Linux
+- Keeps tests fast and deterministic (no actual system calls)
+
+### Example Test Structure
+
+```typescript
+import { describe, it, expect } from "vitest";
+
+describe("FeatureName", () => {
+  it("handles the normal case correctly", () => {
+    // Arrange
+    const input = "test data";
+
+    // Act
+    const result = functionUnderTest(input);
+
+    // Assert
+    expect(result).toBe("expected output");
+  });
+
+  it("handles edge cases gracefully", () => {
+    // Test edge cases...
+  });
+});
+```
+
+### Adding Tests for All Changes
+
+Every change — features, bug fixes, refactors — must include tests:
+
+1. **Before implementing**: Consider what needs testing (happy path, edge cases, errors)
+2. **During implementation**: Write tests alongside the code
+3. **After implementation**: Run `pnpm test:coverage` to verify coverage remains high
+4. **Before committing**: Ensure `check-all.sh` passes (includes all tests)
+
+**Do not commit changes without tests.** The goal is to maintain near-100% coverage as the codebase grows, so future refactoring can be done with confidence!
+
+## Quality Assurance
+
+Before committing any changes, **always run the full test suite**:
+
+```bash
+./check-all.sh
+```
+
+This script runs all checks in the correct order:
+
+1. Frontend linting (ESLint)
+2. Frontend formatting (Prettier)
+3. Frontend type checking (svelte-check)
+4. Frontend tests with coverage (Vitest)
+5. Backend linting (Clippy with strict rules)
+6. Backend tests with coverage (cargo test + llvm-cov)
+
+**Important**: The script requires Node.js and Rust toolchains to be available:
+
+- **Node.js tools** (pnpm, npm): Source nvm first if needed: `source ~/.nvm/nvm.sh`
+- **Rust tools** (cargo, clippy): Should be in PATH via `~/.cargo/bin/`
+
+If `check-all.sh` reports any failures:
+
+1. Read the error messages carefully - they usually explain what needs fixing
+2. Fix the issues (linting errors, test failures, etc.)
+3. Run `check-all.sh` again to verify the fixes
+4. Only commit once all checks pass ✨
+
+**Never commit code that doesn't pass `check-all.sh`** - this ensures code quality and prevents broken builds!

+# Hikari Desktop — Codebase Map
+
+> Auto-generated codebase overview. Last updated: 2026-03-06.
+
+## Overview
+
+Hikari Desktop is a **Tauri v2** desktop application that wraps the Claude Code CLI with a visual anime character avatar (Hikari) who appears on-screen and reacts in real-time to Claude's activity. When Claude is thinking, she thinks. When it's editing code, she codes. When it's using MCP tools, she glows with magical energy.
+
+The app supports multiple simultaneous conversations (tabs), each with its own isolated Claude CLI process. It provides a rich UI layer on top of Claude Code, including a built-in file editor, git panel, achievement system, cost tracking, session history, notifications, and more.
+
+**Repositories:**
+
+- Primary: `git.nhcarrigan.com` (Gitea) — `nhcarrigan/hikari-desktop`
+- Mirror: `github.com/naomi-lgbt/hikari-desktop`
+
+**Current version:** `1.10.0`

+
+## Key Components
+
+### Backend (Rust)
+
+#### `wsl_bridge.rs` — Claude CLI Process Manager
+
+The most critical backend file. `WslBridge` spawns a single `claude` CLI process per conversation using `--output-format stream-json`, which causes Claude Code to emit NDJSON messages on stdout. A dedicated reader thread consumes stdout line-by-line, parses each line into a `ClaudeMessage` enum variant, and emits the appropriate frontend events.
+
+Key responsibilities:
+
+- Locates the `claude` binary (checks `~/.local/bin`, `~/.claude/local`, system paths, and falls back to a login-shell `which claude`)
+- Detects WSL environment to handle cross-platform path differences
+- Maps tool names to character states (Read/Glob/Grep → `searching`, Edit/Write → `coding`, `mcp__*` → `mcp`)
+- Batches permission requests from a single assistant message
+- Tracks token usage per session
+
+#### `bridge_manager.rs` — Multi-Conversation Orchestrator
+
+`BridgeManager` holds a `HashMap<String, WslBridge>` keyed by `conversation_id`. This enables true parallel conversations — each tab has its own isolated Claude process. The manager is wrapped in `Arc<Mutex<BridgeManager>>` (using `parking_lot`) and injected into Tauri's managed state.
+
+#### `types.rs` — Shared Type Definitions
+
+Defines the complete Claude stream-JSON protocol as Rust enums/structs:
+
+- `ClaudeMessage` — top-level message variants: `System`, `Assistant`, `User`, `StreamEvent`, `Result`, `RateLimitEvent`
+- `ContentBlock` — `Text`, `Thinking`, `ToolUse`, `ToolResult`
+- `CharacterState` — `Idle | Thinking | Typing | Searching | Coding | Mcp | Permission | Success | Error`
+- All frontend event types (`OutputEvent`, `StateChangeEvent`, `PermissionPromptEvent`, `AgentStartEvent`, etc.)
+
+#### `commands.rs` — IPC Command Handlers
+
+Registers all Tauri commands exposed to the frontend. Over 80 commands covering: Claude process management, configuration, stats, sessions, git, clipboard, cost tracking, MCP servers, plugins, drafts, snippets, quick actions, file system operations, authentication, and notifications.
+
+#### `debug_logger.rs` — In-App Debug Console
+
+A custom `tracing` subscriber layer (`TauriLogLayer`) that captures all `tracing::info!/warn!/error!` calls and emits them as `debug:log` events to the frontend debug console — essential since production Windows builds have no stdout.
+
+---
+
+### Frontend (TypeScript/Svelte 5)
+
+#### `src/routes/+page.svelte` — Root Layout
+
+The main page. Renders a two-panel layout:
+
+- **Left panel**: `<AnimeGirl>` character display with state-reactive glow effects (trans pride gradient colours per state)
+- **Right panel**: `<Terminal>` + `<InputBar>` (or `<EditorPanel>` when the editor is open)
+
+Also handles: global keyboard shortcuts, compact mode (280×400 mini widget), window close confirmation, Discord RPC updates, and background image loading.
+
+#### `src/lib/tauri.ts` — Event Bridge
+
+Sets up all Tauri event listeners on app mount. Translates backend events into store mutations:
+
+| Event                    | Action                                                                  |
+| ------------------------ | ----------------------------------------------------------------------- |
+| `claude:connection`      | Updates conversation connection status; sends greeting on first connect |
+| `claude:state`           | Updates character state; triggers per-conversation sound effects        |
+| `claude:output`          | Appends lines to the correct conversation's terminal history            |
+| `claude:session`         | Stores the Claude session ID                                            |
+| `claude:cwd`             | Updates working directory (used by the editor)                          |
+| `claude:permission`      | Adds permission requests to conversation state                          |
+| `claude:agent-start/end` | Updates agent monitor panel                                             |
+| `claude:question`        | Stores pending user question                                            |
+
+Also manages Discord RPC updates and the session greeting flow.
+
+#### `src/lib/stores/conversations.ts` — Core State Store
+
+The central state container. Each conversation (`Conversation` interface) tracks:
+
+- Terminal lines (`TerminalLine[]`)
+- Connection status, session ID, working directory
+- Character state, processing flag
+- Granted/pending tool permissions
+- Pending user questions
+- Scroll position, attachments, draft text
+- Sound tracking (per-conversation, prevents replays on tab switch)
+- Conversation summary (for compaction)
+
+Tab names are randomly chosen from a curated list of whimsical names (Starfall, Moonbeam, Sakura, etc.).
+
+#### `src/lib/stores/claude.ts` — Backwards-Compat Facade
+
+A thin wrapper that re-exports `conversationsStore` methods under the original `claudeStore` API. Maintains backwards compatibility whilst the codebase migrated to multi-conversation support.
+
+#### `src/lib/stores/character.ts` — Character State Store
+
+Manages the global character state displayed by `<AnimeGirl>`. Supports `setState()` (persistent) and `setTemporaryState(state, durationMs)` (auto-reverts to `idle` after a timeout — used for success/error flashes).
+
+#### `src/lib/utils/stateMapper.ts` — Stream → State Mapping
+
+Pure utility that maps Claude stream-JSON message types to `CharacterState` values. Tool categorisation mirrors the Rust side: search tools → `searching`, coding tools → `coding`, MCP tools → `mcp`, Task tool → `thinking`.
+
+#### `src/lib/components/`
+
+Key components beyond the basics:
+
+| Component                   | Purpose                                                       |
+| --------------------------- | ------------------------------------------------------------- |
+| `AnimeGirl.svelte`          | Displays the character sprite, subscribes to `characterState` |
+| `Terminal.svelte`           | Renders the conversation message history                      |
+| `InputBar.svelte`           | User input with slash command menu, attachment support        |
+| `StatusBar.svelte`          | Top bar: connection indicator, token/cost stats, controls     |
+| `ConversationTabs.svelte`   | Multi-tab navigation with per-tab status indicators           |
+| `ConfigSidebar.svelte`      | Settings panel (model, theme, notifications, budget, etc.)    |
+| `PermissionModal.svelte`    | Handles tool permission grant/deny UI                         |
+| `UserQuestionModal.svelte`  | Renders `AskUserQuestion` prompts from Claude                 |
+| `AgentMonitorPanel.svelte`  | Live subagent tree with status badges                         |

+## Data Flow
+
+### User Sends a Message
+
+```
+User types → InputBar
+  → invoke("send_prompt", { conversationId, message })
+  → BridgeManager.send_prompt(conversation_id, message)
+  → WslBridge.send_message() → writes JSON to Claude CLI stdin
+```
+
+### Claude Responds (NDJSON Stream)
+
+```
+Claude CLI stdout (NDJSON)
+  → WslBridge reader thread (line-by-line)
+  → serde_json::from_str::<ClaudeMessage>()
+  → match message type:
+      System(init)     → emit claude:connection(connected) + claude:cwd
+      StreamEvent      → emit claude:state(thinking|typing|searching|coding|mcp)
+      Assistant        → emit claude:output(assistant|tool|thinking lines)
+      User(tool_result)→ emit claude:output(tool result lines)
+      Result(success)  → emit claude:state(success) + claude:output(result)
+      Result(error)    → emit claude:state(error)
+      RateLimitEvent   → emit claude:output(rate-limit line)
+      PermissionRequest→ emit claude:permission
+```
+
+### Frontend Reacts
+
+```
+tauri.ts event listeners
+  → conversationsStore mutations
+  → Svelte reactivity propagates to components
+  → AnimeGirl.svelte: sprite changes to match characterState
+  → Terminal.svelte: new line appended
+  → StatusBar.svelte: token counts update
+  → ConversationTabs.svelte: tab glow colour updates
+```
+
+### Permission Flow
+
+```
+Claude requests tool permission
+  → WslBridge batches pending tool uses
+  → emit claude:permission (one or more requests)
+  → tauri.ts → claudeStore.requestPermissionForConversation()
+  → PermissionModal.svelte renders
+  → User clicks Allow/Deny
+  → invoke("answer_question", { conversationId, toolUseId, granted })
+  → WslBridge.send_tool_result() → writes result to Claude stdin
+  → Claude CLI resumes
+```
+
+---
+
+## State Machine
+
+The `CharacterState` enum drives both the sprite displayed and the panel glow colour:
+
+| State        | Trigger                           | Sprite                  | Panel Glow             |
+| ------------ | --------------------------------- | ----------------------- | ---------------------- |
+| `idle`       | Connected, no activity            | Standing with clipboard | None                   |
+| `thinking`   | Thinking block / Task tool        | Hand on chin            | Purple/trans gradient  |
+| `typing`     | Text content block                | At keyboard             | Blue/trans gradient    |
+| `searching`  | Read/Glob/Grep/WebSearch/WebFetch | Magnifying glass        | Yellow/trans gradient  |
+| `coding`     | Edit/Write/NotebookEdit           | At monitor              | Green/trans gradient   |
+| `mcp`        | Any `mcp__*` tool                 | Magical blue energy     | Trans pride vibrant    |
+| `permission` | Permission requested              | Confused shrug          | —                      |
+| `success`    | Result: success                   | Celebrating             | Emerald/trans gradient |
+| `error`      | Result: error                     | Worried                 | Red/trans gradient     |
+
+`success` and `error` are temporary states (3-second auto-revert to `idle`).

+## Development Notes
+
+### Running the App
+
+```bash
+# Frontend dev server only
+source ~/.nvm/nvm.sh && pnpm dev
+
+# Full Tauri app (Rust + frontend)
+source ~/.nvm/nvm.sh && pnpm tauri dev
+```
+
+### Running Tests
+
+```bash
+# All checks (lint → format → type-check → frontend tests → backend tests)
+./check-all.sh
+
+# Frontend tests only
+source ~/.nvm/nvm.sh && pnpm test
+
+# Frontend with coverage
+source ~/.nvm/nvm.sh && pnpm test:coverage
+
+# Backend tests only
+pnpm test:backend
+```
+
+### Building
+
+```bash
+# Linux build
+pnpm build:linux
+
+# Windows cross-compile (requires cargo-xwin)
+pnpm build:windows
+```
+
+### Adding a New Tauri Command
+
+1. Add the handler function in the appropriate `src-tauri/src/*.rs` file with `#[tauri::command]`
+2. Register it in `lib.rs` `invoke_handler![]`
+3. Call it from the frontend via `invoke("command_name", { args })` in `src/lib/tauri.ts` or a store
+
+### Adding a New Frontend Store
+
+1. Create `src/lib/stores/my-store.ts` using `writable` or a factory function pattern
+2. Create `src/lib/stores/my-store.test.ts` — all stores must have tests
+3. Expose the store from the appropriate component
+
+### Claude Stream-JSON Protocol
+
+Claude Code is invoked with `--output-format stream-json --verbose`. See `src-tauri/src/types.rs` for the complete message type definitions. The key field distinguishing subagent messages from top-level messages is `parent_tool_use_id` on `Assistant` messages.
+
+### Multi-Conversation Architecture
+
+Each tab (`Conversation`) in `conversationsStore` has a unique `conversation_id` string. The backend `BridgeManager` maps these IDs to `WslBridge` instances. All Tauri events carry `conversation_id` in their payload so the frontend can route them to the correct conversation without affecting others.
+
+### WSL Detection
+
+`wsl_bridge.rs` detects WSL by checking `/proc/version` for "microsoft"/"wsl" strings, checking for `/proc/sys/fs/binfmt_misc/WSLInterop`, and checking `$WSL_DISTRO_NAME`. On native Windows builds, WSL detection always returns `false` (even if launched from a WSL terminal).
+
+### Character State Sound Rules
+
+Sound effects are managed in `src/lib/tauri.ts` per-conversation to prevent replays when switching tabs. The rules are:
+
+- Entering `thinking` from a clean state (`idle`/`success`/`error`) → reset all sound flags
+- Entering `coding` or `searching` (first time per task) → play task-start sound
+- Entering `success` after ≥2 seconds in a long-running phase → play completion sound
+- Entering `error` → play error sound (always)
+- Entering `permission` → play permission sound (always)
+
+### Workspace Trust Gate
+
+On first connection to a new working directory, the app checks for Claude hooks and prompts the user to trust the workspace. Trusted workspaces are persisted in `HikariConfig.trusted_workspaces`.
+
+### Configuration Storage
+
+All settings are persisted via `tauri-plugin-store` to a JSON file in the app data directory. The frontend `configStore` (`src/lib/stores/config.ts`) loads configuration on startup and provides reactive derived stores. Changes invoke `save_config` to persist to disk.

+# Project Overview
+
+## What is this project?
+
+Hikari Desktop is a Tauri-based desktop application that wraps Claude Code with a visual anime character companion (Hikari) who appears on screen. It provides a rich UI for interacting with Claude Code, including conversation management, agent monitoring, cost tracking, and more.
+
+The app was inspired by a Hatsune Miku mod for the ship AI in _The Outer Worlds_ — the idea of an AI assistant with an anime girl avatar that you can actually _see_.
+
+## Goals
+
+- Provide a beautiful, personalised interface for Claude Code
+- Surface real-time status (thinking, typing, searching, etc.) through animated character sprites
+- Track costs, context usage, and agent activity across sessions
+- Support power-user workflows: multi-tab conversations, todo lists, git integration, MCP server management, session compaction, and more
+- Build a foundation for autonomous task execution (agent orchestration, PRD-driven workflows)
+
+## Tech Stack
+
+- **Frontend**: Svelte 5 + TypeScript + Tailwind CSS
+- **Backend**: Rust (Tauri v2)
+- **Build**: Vite + pnpm
+- **Testing**: Vitest (frontend) + cargo test (backend)
+- **Linting**: ESLint + Prettier (frontend) + Clippy (backend)
+- **IPC**: Tauri commands + events between Rust and Svelte
+
+## Architecture

+```
+
+Claude Code is launched as a child process via `WslBridge`, communicating via `--output-format stream-json` (NDJSON). Messages flow from the Rust backend to the Svelte frontend via Tauri events.

+/**
+ * ChangelogPanel Component Tests
+ *
+ * Tests the pure helper function exported by ChangelogPanel for formatting
+ * ISO 8601 date strings into human-readable release dates.
+ *
+ * What this component does:
+ * - Opens as a modal dialog from the nav menu
+ * - Fetches all releases via the `fetch_changelog` Tauri IPC command on mount
+ * - Shows a loading spinner while fetching
+ * - Renders each release with version badge, date, pre-release badge, and notes
+ * - Highlights the currently installed version with a pink "current" badge
+ * - Provides a "View on Gitea" link per release
+ * - Shows an error state with a Retry button if the fetch fails
+ *
+ * Manual testing checklist:
+ * - [ ] Changelog item appears in the nav dropdown
+ * - [ ] Clicking opens the panel with a loading spinner
+ * - [ ] Spinner resolves to a list of releases
+ * - [ ] Current version entry shows pink version text + "current" badge
+ * - [ ] Pre-release entries show a yellow "pre-release" badge
+ * - [ ] "View on Gitea" opens the release URL in the browser
+ * - [ ] Backdrop click and Escape key close the panel
+ * - [ ] Network error shows a red error message and a Retry button
+ * - [ ] Retry button re-fetches the changelog

+/**
+ * ConversationTabs Component Tests
+ *
+ * Tests the connection status colour mapping and unread message detection
+ * logic used by the ConversationTabs component.
+ *
+ * What this component does:
+ * - Displays one tab per conversation
+ * - Each tab shows a coloured dot for its connection state
+ * - Inactive tabs with new messages show an animated blue dot badge
+ * - Tabs can be renamed by double-clicking
+ * - Tabs can be reordered by drag-and-drop
+ * - New tabs created with Ctrl+T, closed with Ctrl+W
+ *
+ * Manual testing checklist:
+ * - [ ] Connected tabs show a green dot
+ * - [ ] Connecting tabs show a yellow dot
+ * - [ ] Disconnected tabs show a red dot
+ * - [ ] Active tab never shows the unread badge
+ * - [ ] Inactive tab shows blue pulsing dot when it receives new messages
+ * - [ ] Switching to a tab clears the unread indicator
+ * - [ ] Double-clicking a tab name enables inline editing
+ * - [ ] Tabs can be dragged to reorder
