Struct ConfigLayers 

pub struct ConfigLayers<'a> {
    pub project_toml: Option<&'a str>,
    pub local_toml: Option<&'a str>,
    pub settings: &'a [String],
    pub overrides: &'a [String],
}

BP-9 (D6 rows “Layered config w/ precedence” + “Inline per-run config override”): every layer that sits ABOVE the trusted user/global file, lowest priority first. Passing ConfigLayers::default() is exactly today’s single-project-layer behavior.

The precedence line, lowest to highest (§3.3, cx§6’s mdm → system → user → profile → project → flags ordering):

  built-in defaults
< preset chain (`extends`, root-first)
< user / global file            (~/.config/supercode/config.toml)
< selected profile              (`--profile <name>`, CLI-side layer)
< project file                  (.supercode.toml            — UNTRUSTED)
< project-local file            (.supercode.local.toml      — UNTRUSTED)
< `--settings <json|path>`      (per-run, typed at launch)
< `-c/--config key=value`       (per-run, typed at launch)
< individual CLI flags

The two UNTRUSTED layers are sanitized and clamped INDIVIDUALLY before merge — .supercode.local.toml is gitignored by convention, and a convention is not a trust boundary: nothing stops a repo from committing one. It therefore gets the identical §3.3 treatment as .supercode.toml, and buys precedence over the checked-in project file (its actual purpose: your own per-checkout overrides), never new authority.

The two per-run layers ARE trusted: a --settings/-c value was typed on the command line by the person running the tool, the same trust level as any other flag. They are applied THROUGH this resolver rather than poked onto the materialized Config, so a per-run override can never bypass the project sanitization/clamping that already ran below it.

Fields

project_toml: Option<&'a str>

.supercode.toml text (untrusted).

local_toml: Option<&'a str>

.supercode.local.toml text (untrusted; per-user by convention).

settings: &'a [String]

--settings documents: inline JSON ({…}), inline TOML, or a path to a .json/.toml file. Applied in order.

overrides: &'a [String]

-c/--config key=value assignments, dotted TOML keys with TOML-typed values. Applied last, in order.
