Vegas bakes each plugin's pictures into one strip, so a card already on its way across the panel keeps what it showed when it was drawn. This adds the API and bookkeeping for content that can be updated in place; the worker that redraws and swaps it follows separately. No shipped plugin implements the hook yet, so nothing changes for users. Plugin API (core 3.8.0), all no-ops by default: - BasePlugin.get_vegas_elements() -> [VegasElement(key, image, version, live, refresh_hz)]: named, fixed-width pieces of Vegas content. - BasePlugin.redraw_vegas_element(key, width, height, at): a lock-free redraw for content that changes with time. - BasePlugin.notify_vegas_data_changed(): data that lands outside update(). - src/plugin_system/vegas_elements.py (VegasElement, re-exported from base_plugin). Core: - PluginAdapter asks a plugin that implements the hook for elements on the background fetch only (under its lock, on its own canvas); every other path keeps get_vegas_content(). Live elements are pinned (padded with content_padding, never trimmed), tagged with their key, digest and data epoch in Image.info so the existing cache and group plumbing carry them unchanged, and untagged if a width budget crops them. - RenderPipeline records where each live element lands (ElementRecord), in absolute strip columns a trim does not move; the block-start arithmetic is shared with the STATIC markers. - PluginManager update listeners (add/remove_update_listener, notify_data_changed): told the moment update() completes, not at the next ~4s Vegas poll. The coordinator uses one to move each plugin's data epoch on. - vegas_scroll.live_refresh (kill switch), live_max_hz, live_min_interval, live_lead_screens; per-plugin core-owned vegas_live. Live elements are off under multi-display sync, in swap mode and with offscreen_prefetch off. - scripts/check_plugin.py checks the element contract (src/plugin_system/testing/vegas.py); test/fixtures/plugins/vegas-live-stub is a working example.

Scripts
Helper scripts for installing, repairing, diagnosing and developing LEDMatrix. Most users only ever run the one-shot installer (see the project README); everything else here is for troubleshooting or development.
Status key: keep — part of install/runtime or referenced by docs, CI, tests or code; dev-only — for plugin/core development, not needed on a display; diagnostic — run by hand on a Pi when something is wrong.
Directories
| Directory | Status | What it holds |
|---|---|---|
install/ |
keep | The installers: one-shot, services, sudoers/WiFi permissions, cache setup, and the shared lib_*.sh helpers first_time_install.sh sources |
fix_perms/ |
keep | Permission repair scripts, plus the two root helpers the web interface runs through sudo (safe_plugin_rm.sh, safe_pip_install.sh) |
utils/ |
keep | Scripts run by systemd units or the web interface (conditional web start, WiFi monitor, update verify, DNS fix, Pixlet config editor, cache clearing) |
dev/ |
dev-only | Plugin linking, emulator runner, Vegas density audit, Pillow smoke test |
templates/ |
dev-only | dev_preview.html, the page dev_server.py serves |

Candidates for removal
Nothing in the repo (docs, CI, tests, other scripts or code) refers to these. They are kept for now; each one needs an owner decision before it goes.

analyze_plugin_schemas.py |
One-off: reports duplicate/inconsistent fields across plugin schemas |
