Coral stores local configuration in config.toml inside its platform-specific local state directory.

​
Managed state

Coral writes source installation state to config.toml when you run commands such as coral source add and coral source remove. This state includes installed-source metadata and non-secret source variables. Source secrets are stored separately within the same local trust boundary.
Prefer the coral source commands for source state instead of editing workspace entries manually.

​
Runtime features

Experimental runtime features are configured under [features]. 
[features]
feedback = true
You can inspect available features and their effective state with: 
coral features list
Enable or disable a feature with: 
coral features enable feedback
coral features disable feedback
Feature values must be booleans. Unknown feature keys are preserved in config.toml but ignored by Coral.
