ChuckBuildsandClaude Opus 5 d2379a1eb6 fix(web): stop /config/secrets handing out every credential it holds

GET /api/v3/config/secrets returned config_secrets.json in full to anyone who
could reach the port, and this interface has no authentication. Probed against
a real rig it produced six populated credential fields: a 40-character GitHub
token, a 183-character Home Assistant token, and Jellyfin and weather API keys.
This is the second door onto the same credentials; #477 closes the first.

Masking the response alone would have been worse than the leak. The only
client fetches every secret, edits one field and posts all of them back, and
save_raw_file_content replaces the file wholesale -- so a masked GET followed
by the client's own save would write the mask over every credential the user
had not touched. That is why this was left open when the leak was found; it
needs both halves.

Read side: mask_all_secret_values(), which already existed for exactly this
endpoint -- its docstring names it -- and had never been wired to a call site.
It leaves empty values and YOUR_* placeholders alone, so a client can still
tell "set" from "not set" without being told the secret.

Write side: strip the echoed mask and blanks from the submission, then merge
onto what is stored, so "unchanged" means unchanged. The cost is that a secret
can no longer be cleared by blanking it; that wants its own affordance, since
a control that erases credentials as a side effect of saving an unrelated one
is not one.

Browser side: the token field is now left empty rather than filled from the
response. Filling it with the mask would have stored eight bullet characters
as the token the next time the user pressed Save, and filling it with the real
value is the thing being fixed. It reports whether a token is saved instead.

Verified end to end through the Flask endpoints, not the helpers. Reverting
the masking fails the leak tests; reverting the merge fails the preservation
tests; both halves are independently guarded. 278 web tests pass.

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
