+## Marking Fields as Advanced (`x-advanced`)
+
+Add `"x-advanced": true` to any top-level, non-object property to move it out
+of the main form and into a single collapsed **Advanced Settings** section at
+the bottom of the plugin's configuration page:
+
+```json
+{

+Guidelines:

+- Use it for fine-tuning knobs most users never touch (timeouts, retry
+  behavior, cache TTLs, styling overrides). Anything a first-time user must
+  set to get the plugin working should stay basic.
+- Nothing is hidden permanently — the section expands on click, and the
+  settings search finds and auto-expands advanced fields like any others.
+- The flag is ignored on `object`-type properties (they already render as
+  their own collapsible sections) and is safely ignored by older cores, so
+  adding it never breaks compatibility.

-# Example usage and benefits:
-"""
-Benefits of using LEDMatrix Common helpers:
-
-1. **Cleaner Code**: The plugin is much shorter and more readable
-2. **Reusable Components**: Common functionality is shared across plugins
-3. **Better Testing**: Each helper can be tested independently
-4. **Easier Maintenance**: Bug fixes in helpers benefit all plugins
-5. **Consistent Behavior**: All plugins use the same underlying logic
-6. **Reduced Dependencies**: Plugins don't need to import LEDMatrix core
-7. **Better Error Handling**: Centralized error handling in helpers
-8. **Configuration Management**: Consistent config handling across plugins
-
-The original basketball plugin was 326 lines. This version is much cleaner
-and delegates most functionality to the common helpers, making it easier to
-maintain and extend.

+"""Tests for asynchronous plugin updates (plugin_manager background worker).

+The invariants that keep this change safe:
+1. run_scheduled_updates returns immediately — a slow update() can never
+   again freeze the render loop (the original defect: 30s scroll freezes).
+2. A plugin's update() and display() are NEVER concurrent — the per-plugin
+   lock makes the old implicit no-overlap guarantee explicit, and it stays
+   held through PluginExecutor's own timeout: a lingering, still-running
+   update() keeps the lock even after PluginExecutor gives up waiting on it.
+3. Failure/timeout bookkeeping is unchanged (same executor, same
+   _record_update_failure path, same last-update stamping).
+4. The kill switch (plugin_system.synchronous_updates) restores the
+   inline path exactly.

+Static-analysis audits for the web UI, as tests so CI enforces them.

+1. Breakpoint utility audit: app.css hand-maintains a Tailwind-style utility

+   that no CSS rule defines — it silently no-ops. This once left the header
+   search box and system stats invisible at every screen width. The audit
+   diffs classes used in templates against classes defined in app.css.
+
+2. Asset reference audit: every url_for('static', filename=...) in the
+   templates must point to a file that exists, so a renamed/moved asset
+   can't ship as a broken <script>/<link>/<img>.
+
+3. debugLog globals audit: any static JS file calling debugLog() (a global
+   defined in base.html) must declare it in a /* global */ header so linting
+   stays clean and the dependency is explicit.
