Enum ConfigLayer 

pub enum ConfigLayer {
    Defaults = 0,
    User = 1,
    Profile = 2,
    Project = 3,
    Session = 4,
}

One source of configuration in the layered merge. Declaration order IS precedence: every later layer’s table is deep-merged over the earlier ones, so Defaults < User < Profile < Project < Session.

Variants

Defaults = 0

Built-in defaults (Config::default()); the implicit base — an empty table deserializes to it, so no explicit table is ever built for it.

User = 1

The user’s ~/.config/mermaid/config.toml — the only layer persists write to.

Profile = 2

A named overlay from the user file’s [profiles.<name>], selected with --profile <name>. Sits BELOW Project so a repo’s tighten-only safety clamp still wins over a profile’s choices.

Project = 3

A repo’s <git-root>/.mermaid/config.toml (sanitized + tighten-only; populated by the project-config loader).

Session = 4

This invocation’s CLI flags: -c KEY=VALUE plus the dedicated flags (--no-network, --confine-fs, --sandbox, run --max-tokens, run --allow-untrusted-tools).
