Whole-tree audit. Every symbol was checked against core, the plugin
monorepo and all eight third-party plugins in plugins.json first.
- Deprecate (removal 3.10.0) plugin-facing methods nothing calls:
LogoDownloader bulk download, ConfigManager backup/secret wrappers,
APIHelper extras, BackgroundDataService poll API, PluginManager /
PluginStateManager info readers, and a few CacheManager, FontManager,
BaseOddsManager, DynamicTeamResolver methods and PluginTestCase.
plugin_api_usage.py learns their receiver names; DEPRECATIONS doc
regenerated.
- Remove core-internal dead code: CacheMetrics, Vegas status/stats
plumbing, sync "new cycle" message (followers ignore unknown types),
unused operation types, test-only PluginCatalog readers, IPC to_dict
and ping, _parse_form_value, CacheStrategyProtocol, ErrorAggregator
callbacks, duplicate web response helpers.
- Web UI: drop never-mounted json-file-manager.js, the example widget,
utils/error_handler.js, four uncalled PluginAPI methods, and 29
escapeHtml shims (call window.LEDEscape directly). Public globals,
BaseWidget and widget names unchanged.
- Remove six one-off scripts (owner decision) and the unused markupsafe
and pytest-mock pins.

Vegas scrolls a whole number of pixels per panel refresh, locked to SwapOnVSync, against the refresh the panel really holds (measured from swap gaps), instead of blending sub-pixel positions against the refresh cap. The web preview PNG is encoded off the render thread while scrolling, with writes ordered and retried. On hdpi, late frames fell from 6.3% to 0.7%. See docs/SCROLL_PERFORMANCE.md.
