- load_plugin: an on_enable() that raises unregisters the instance, so the next load retries instead of returning True "already loaded". - get_plugin_info: guard plugin.get_info(); one plugin raising no longer breaks /api/v3/plugins/installed. - plugin_state.json and the operation history are written with atomic_write_text under their lock. - plugin_loader: module-level lock serialises pip installs across the parallel startup loaders. - store_manager._install_via_download: extract dir cleanup moved to finally. - Test doubles: draw_image() warns (DeprecationWarning; the real DisplayManager has none), MockDisplayManager.draw_text accepts the real signature's optional params, VisualTestDisplayManager logs draw errors at WARNING. - Docs/comments: compatibility.py method name, PluginState.LOADED meaning, brittle schema count, why _report_skip_once uses setdefault. - Remove unused PluginOperationQueue.get_active_operations().

harness bug in the abstract, it's a plugin silently failing to render

get_cached_data_with_strategy() and previously hit an AttributeError that

its own broad except swallowed, producing an empty-but-green render).
