 | [NERV Theme](guide_nerv_theme.md) | "Black Void" palette with NERV orange/red/green/blue accents, zero-rounding geometry, CRT-style visual effects (scanlines, status flickering, alert animations), `theme_nerv.py` and `theme_nerv_fx.py` modules, FBO shader pipeline, configuration keys, performance cost, accessibility caveats |
 | [Workspace Profiles](guide_workspace_profiles.md) | Docking layouts and window visibility persistence, `WorkspaceProfile` schema with serialized `docking_layout` bytes, `WorkspaceManager` CRUD, scope inheritance (Global and Project), contextual auto-switch (experimental) binding profiles to MMA tier or task context, multi-monitor limitations |
 | [Command Palette](guide_command_palette.md) | Fuzzy command resolution with subsequence matching and scoring, async context preview worker to prevent UI hangs, "Everything" mode for cross-domain search (commands, files, symbols, history, settings), streaming results via thread-safe queue, cancellation on query change, 50+ built-in commands, user-defined commands via TOML |
-| [Testing](guide_testing.md) | 251 test files, 5 test categories (unit, integration, live_gui, perf, simulation), 7 conftest fixtures (`isolate_workspace`, `reset_paths`, `reset_ai_client`, `vlogger`, `kill_process_tree`, `mock_app`, `live_gui` session-scoped), Hook API testing pattern, Puppeteer pattern for MMA simulation, mock provider strategy, opt-in clean install test, opt-in docker test, coverage targets, anti-patterns (no arbitrary core mocking, artifact isolation to `tests/artifacts/`) |
-| [GUI Main](guide_gui_2.md) | `src/gui_2.py` reference: App class lifecycle, ~90 module-level render functions (UI Delegation Pattern), immgui immediate-mode rendering, Multi-Viewport docks, panel registry, command palette integration, ImGuiScope context managers, hot reload support, key bindings (Ctrl+Shift+P, Ctrl+Alt+R, Ctrl+Z/Y) |

+| [Themes](guide_themes.md) | TOML-based theming system: file layout (`themes/<name>.toml` global + `project_themes.toml` per-project), schema (`syntax_palette` + `[colors]` table with `imgui.Col_` snake_case keys), 4-syntax-palette upstream limit (`imgui-bundle` ships `dark`/`light`/`mariana`/`retro_blue` only), built-in vs TOML palette dispatch, `load_themes_from_disk` / `get_syntax_palette_for_theme` / `apply_syntax_palette` public API, hot-reload behavior, color-callable convention (`C_LBL()` / `C_VAL()` for theme-aware helpers) |
+| [GUI Main](guide_gui_2.md) | `src/gui_2.py` reference: App class lifecycle, ~90 module-level render functions (UI Delegation Pattern), immgui immediate-mode rendering, Multi-Viewport docks, panel registry, command palette integration, ImGuiScope context managers, hot reload support, key bindings (Ctrl+Shift+P, Ctrl+Alt+R, Ctrl+Z/Y), `_capture_workspace_profile` defer-not-catch pattern (line 601-606, `_ini_capture_ready` flag for `imgui.save_ini_settings_to_memory`), theme color-callable pattern (e.g. `DIR_COLORS`/`KIND_COLORS` dicts store `C_VAL` not `C_VAL()` and are called at use site) |
 | [AI Client](guide_ai_client.md) | `src/ai_client.py` reference: multi-provider LLM singleton (5 providers: Gemini, Anthropic, DeepSeek, MiniMax, Gemini CLI), async dispatch with `asyncio.gather`, threading.local for source tier tagging, context caching (Anthropic ephemeral + Gemini explicit), system prompt assembly, error interception for Tier 4 QA |
 | [API Hooks](guide_api_hooks.md) | `src/api_hooks.py` + `src/api_hook_client.py` reference: HookServer on `127.0.0.1:8999`, ApiHookClient Python wrapper, 8+ endpoints (`/status`, `/api/gui`, `/api/ask`, `/api/gui/mma_status`, `/api/performance`, `/api/comms`, `/api/diagnostics`), Remote Confirmation Protocol via `/api/ask` (synchronous blocking HITL), `custom_callback` action for invoking any registered App method |
 | [MCP Client](guide_mcp_client.md) | `src/mcp_client.py` reference: 45 native tools (File I/O, Python AST, C/C++ AST, Analysis, Network, Runtime, Beads), 3-layer security model (Allowlist Construction, Path Validation, Resolution Gate), `dispatch()`/`async_dispatch()` entry points, ExternalMCPManager for external MCP servers (Stdio + SSE), JSON-RPC 2.0 engine, public API, configuration |
