Enum ConfigSlotSuppliedBy 

pub enum ConfigSlotSuppliedBy {
    Environment,
    Platform,
    Runtime,
}

Single [[config_slots]] entry — a config value the TARGET environment must fill for this server to run.

A Shape A server’s whole identity is its config, so “what must the operator supply?” has to be declarable IN that config rather than discovered by grepping for ${...}. This block is that declaration: it names the config path, the kind of thing it is, and the value exercised when the server was tested.

Additive per the REF-01 superset invariant — a config omitting the block parses to an empty ServerConfig::config_slots. Strict-parse discipline (D-13) applies: #[serde(deny_unknown_fields)] rejects a typo’d inner key.

Example

[[config_slots]]
key = "backend.base_url"
kind = "endpoint"
name = "TFL_BASE_URL"
tested_value = "https://api.tfl.gov.uk"

Who fills a config slot’s value.

Mirrors pmcp-package’s SuppliedBy by TOML value name, never by shared type — the same arrangement as ConfigSlotKind, and for the same reason: the toolkit must NOT depend on pmcp-package (the workspace-excluded leaf), and a dependency the other way inverts the layering. The agreement is enforced by the package side re-parsing these same config bytes, not by a shared definition.

Defaults to Environment, so every config written before this field existed keeps its exact meaning: the operator supplies it.

Variants

Environment

The operator supplies it in the target environment. The default, and the only class a package enumerates as REQUIRED of an operator.

Platform

The hosting platform injects it at deploy time.

Runtime

The execution environment injects it (e.g. AWS_LAMBDA_FUNCTION_NAME); neither the operator nor the platform supplies it.
