Enum ConfigSource 

pub enum ConfigSource {
    Defaults,
    File(PathBuf),
    EnvVars,
    CliOverlay(Value),
}

One layer of the precedence stack.

Variants

Defaults

Hard-coded defaults (always first).

File(PathBuf)

Config file at the given path. Format auto-detected from the extension: .json, .yaml/.yml, .toml (YAML/TOML require the config-loader feature). Missing / malformed is a hard error; unknown fields are tolerated.

EnvVars

Read JSS_* env vars from std::env.

CliOverlay(Value)

Sprint 11 (row 121): highest-precedence CLI overlay, carried as a pre-built JSON value so the loader can deep-merge it without caring about the CLI parser.
