There was no single place documenting what lives in config.json — display.* keys were scattered across README sections, vegas_scroll lived in ADVANCED_FEATURES.md, and dim_schedule, display.double_sided, sync.follower_position, plugin_system.development_mode and the four newly-templated hardware keys were documented nowhere. CONFIG_REFERENCE.md now lists every template key plus the code-read-only keys, each with type, default, and the code location that reads it, and explains the secrets file's plugin-id namespacing. Linked from the docs index. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SXb4mKcAkVaxkeTb3YnAdr

Configuration Reference
Every key in config/config.json, what it does, its default, and where the
code reads it. The file is created from config/config.template.json on
first run, and ConfigManager._migrate_config() merges any template keys
added by later releases into your existing config (your values are never
overwritten). Secrets live in config/config_secrets.json and are merged
into the config at load time.
Most settings are editable from the web interface; this page documents the
underlying keys for people editing config.json directly or writing
tooling against it.

string, "" — set to "FM6126A" or "FM6127" for panels needing init |
Where "code default" differs from the template value, the code default only applies if the key is missing entirely from your config.

Every installed plugin stores its settings under a top-level key equal to

plugin). The shape of each block is defined by that plugin's
config_schema.json; common keys are enabled and display_duration.
