ChuckBuildsandClaude 94032e2101 Vegas mode: one continuous strip instead of swapping cycles

A cycle used to be a discrete strip that got replaced: motion stopped, every
pixel was substituted at once, and the next group started with the viewport
already full. That is the freeze, the flash and the jump.

The strip is now extended rather than replaced. ScrollHelper gains
append_content(), which adds items on the right without touching
scroll_position or total_distance_scrolled, so motion continues and the next
group simply arrives from the right. Because completion is measured against
total_scroll_width, extending also defers completion — there is no longer a
cycle boundary to see.

drop_scrolled_prefix() reclaims what has gone past, keeping the strip bounded
however long Vegas runs (observed 5,000-11,000px against an unbounded strip
otherwise). It shifts total_distance_scrolled and total_scroll_width together so
the completion arithmetic is unchanged, and refuses to run while the viewport is
wrapping: wrapping reads the head of the strip into the right of the frame, so
trimming the head there would visibly change the picture. A test caught that.

Groups are prepared off the render thread. The constraint is that the canvas and
the matrix proxy are process-wide mutable state, so narrowing or capturing
through them from another thread would corrupt the frame the render loop is
pushing. get_content() therefore takes offscreen_only: the background thread uses
only paths that avoid the canvas, and anything needing it is marked and picked up
on the render thread. That puts the expensive work (native renders of leaderboard
and baseball cards, seconds each) in the background and leaves the cheap work
(display capture, 40-600ms) in the foreground.

DisplayManager's capture flag is now thread-local. As a shared flag, a background
capture would have suppressed the render loop's own frame pushes for its
duration, freezing the panel precisely when the point was to avoid a freeze.

Canvas-bound plugins are drained one at a time rather than as a batch: six at
once held the render thread for 1.75s. Drains are also spaced by two seconds
while the lookahead is healthy, since taking them back to back turns one long
stall into a run of short ones. When the strip is genuinely running short the
throttle is ignored, because content matters more than smoothness there.

Measured on hardware: zero cycle-complete swaps, drains landing 2-4s apart,
lookahead holding at 1,200-3,500px, no errors.

Set continuous_scroll false to restore the swap behaviour; the old path is intact.

LED Matrix Web Interface V3

Modern, production web interface for controlling the LED Matrix display.

Overview

This directory contains the active V3 web interface with the following features:

Real-time display preview via Server-Sent Events (SSE)
Plugin management and configuration
System monitoring and logs
Modern, responsive UI
RESTful API

Running the Web Interface

Standalone (Development)

From the project root:

python3 web_interface/start.py

Or using the shell script:

./web_interface/run.sh

As a Service (Production)

The web interface can run as a systemd service that starts automatically based on the web_display_autostart configuration setting:

sudo systemctl start ledmatrix-web
sudo systemctl enable ledmatrix-web  # Start on boot

Accessing the Interface

Once running, access the web interface at:

Local: http://localhost:5000
Network: http://:5000

Configuration

The web interface reads configuration from:

config/config.json - Main configuration
config/config_secrets.json - API keys and secrets

API Documentation

The V3 API is mounted at /api/v3/ (app.py:144). For the complete list and request/response formats, see docs/REST_API_REFERENCE.md. Quick reference for the most common endpoints:

Configuration

GET /api/v3/config/main - Get main configuration
POST /api/v3/config/main - Save main configuration
GET /api/v3/config/secrets - Get secrets configuration
POST /api/v3/config/raw/main - Save raw main config (Config Editor)
POST /api/v3/config/raw/secrets - Save raw secrets

Display & System Control

GET /api/v3/system/status - System status
POST /api/v3/system/action - Control display (action body: start_display, stop_display, restart_display_service, restart_web_service, git_pull, reboot_system, shutdown_system, enable_autostart, disable_autostart)
GET /api/v3/display/current - Current display frame
GET /api/v3/display/on-demand/status - On-demand status
POST /api/v3/display/on-demand/start - Trigger on-demand display
POST /api/v3/display/on-demand/stop - Clear on-demand

Plugins

GET /api/v3/plugins/installed - List installed plugins
GET /api/v3/plugins/config?plugin_id=<id> - Get plugin config
POST /api/v3/plugins/config - Update plugin configuration
GET /api/v3/plugins/schema?plugin_id=<id> - Get plugin schema
POST /api/v3/plugins/toggle - Enable/disable plugin
POST /api/v3/plugins/install - Install from registry
POST /api/v3/plugins/install-from-url - Install from GitHub URL
POST /api/v3/plugins/uninstall - Uninstall plugin
POST /api/v3/plugins/update - Update plugin

Plugin Store

GET /api/v3/plugins/store/list - List available registry plugins
GET /api/v3/plugins/store/github-status - GitHub authentication status
POST /api/v3/plugins/store/refresh - Refresh registry from GitHub

Real-time Streams (SSE)

SSE stream endpoints are defined directly on the Flask app (app.py:607-619 — includes the CSRF exemption and rate-limit hookup alongside the three route definitions), not on the api_v3 blueprint:

GET /api/v3/stream/stats - System statistics stream
GET /api/v3/stream/display - Display preview stream
GET /api/v3/stream/logs - Service logs stream

Development

When making changes to the web interface:

Edit files in this directory
Test changes by running python3 web_interface/start.py
Restart the service if running: sudo systemctl restart ledmatrix-web

Notes

Templates and static files use the v3/ prefix to allow for future versions
The interface uses Flask blueprints for modular organization
SSE streams provide real-time updates without polling
