+## Troubleshooting
+
+### macOS says the app is damaged
+If macOS reports that "CodeNomad.app is damaged and can't be opened," Gatekeeper flagged the download because the app is not yet notarized. You can clear the quarantine flag after moving CodeNomad into `/Applications`:
+
+```bash
+xattr -l /Applications/CodeNomad.app
+xattr -dr com.apple.quarantine /Applications/CodeNomad.app

+
+After removing the quarantine attribute, launch the app normally. On Intel Macs you may also need to approve CodeNomad from **System Settings → Privacy & Security** the first time you run it.

+# SolidJS Documentation
+
+> Solid is a modern JavaScript framework for building user interfaces with fine-grained reactivity. It compiles JSX to real DOM elements and updates only what changes, delivering exceptional performance without a virtual DOM. Solid provides reactive primitives like signals, effects, and stores for predictable state management.
+
+SolidJS is a declarative JavaScript framework that prioritizes performance and developer experience. Unlike frameworks that re-run components on every update, Solid components run once during initialization and set up a reactive system that precisely updates the DOM when dependencies change.
+
+Key principles:
+- Fine-grained reactivity: Updates only the specific DOM nodes that depend on changed data
+- Compile-time optimization: JSX transforms into efficient DOM operations
+- Unidirectional data flow: Props are read-only, promoting predictable state management
+- Component lifecycle: Components run once, with reactive primitives handling updates

+# opencode-config
+
+## TLDR
+Template config + plugins injected into every OpenCode instance that CodeNomad launches. It provides a CodeNomad bridge plugin for local event exchange between the CLI server and opencode.
+
+## What it is
+A packaged config directory that CodeNomad copies into `~/.config/codenomad/opencode-config` for production builds or uses directly in dev. OpenCode autoloads any `plugin/*.ts` or `plugin/*.js` from this directory.
+
+## How it works
+- CodeNomad sets `OPENCODE_CONFIG_DIR` when spawning each opencode instance (`packages/server/src/workspaces/manager.ts`).
+- This template is synced from `packages/opencode-config` (`packages/server/src/opencode-config.ts`, `packages/server/scripts/copy-opencode-config.mjs`).
+- OpenCode autoloads plugins from `plugin/` (`packages/opencode-config/plugin/codenomad.ts`).
+- The `CodeNomadPlugin` reads `CODENOMAD_INSTANCE_ID` + `CODENOMAD_BASE_URL`, connects to `GET /workspaces/:id/plugin/events`, and posts to `POST /workspaces/:id/plugin/event` (`packages/opencode-config/plugin/lib/client.ts`).
+- The server exposes the plugin routes and maps events into the UI SSE pipeline (`packages/server/src/server/routes/plugin.ts`, `packages/server/src/plugins/handlers.ts`).
+
+## Expectations
+- Local-only bridge (no auth/token yet).
+- Plugin must fail startup if it cannot connect after 3 retries.
+- Keep plugin entrypoints thin; put shared logic under `plugin/lib/` to avoid autoloaded helpers.
+- Keep event shapes small and explicit; use `type` + `properties` only.
+
+## Ideas
+- Add feature modules under `plugin/lib/features/` (tool lifecycle, permission prompts, custom commands).
+- Expand `/workspaces/:id/plugin/*` with dedicated endpoints as needed.
+- Promote stable event shapes and version tags once the protocol settles.
+
+## Pointers
+- Plugin entry: `packages/opencode-config/plugin/codenomad.ts`
+- Plugin client: `packages/opencode-config/plugin/lib/client.ts`
+- Plugin server routes: `packages/server/src/server/routes/plugin.ts`
+- Plugin event handling: `packages/server/src/plugins/handlers.ts`
+- Workspace env injection: `packages/server/src/workspaces/manager.ts`

 npm run build

 The output will be generated in the `dist` directory, which is then consumed by the Server or Electron app.
+
+## Debug Logging
+
+The UI now routes all logging through a lightweight wrapper around [`debug`](https://github.com/debug-js/debug). The logger exposes four namespaces that can be toggled at runtime:
+
+- `sse` – Server-sent event transport and handlers
+- `api` – HTTP/API calls and workspace lifecycle
+- `session` – Session/model state, prompt handling, tool calls
+- `actions` – User-driven interactions in UI components
+
+You can enable or disable namespaces from DevTools (in dev or production builds) via the global `window.codenomadLogger` helpers:
+
+```js
+window.codenomadLogger?.listLoggerNamespaces() // => [{ name: "sse", enabled: false }, ...]
+window.codenomadLogger?.enableLogger("sse") // turn on SSE logs
+window.codenomadLogger?.disableLogger("sse") // turn them off again
+window.codenomadLogger?.enableAllLoggers() // optional helper
+```
+
+Enabled namespaces are persisted in `localStorage` under `opencode:logger:namespaces`, so your preference survives reloads.
