Struct ConfigSlotDecl 

pub struct ConfigSlotDecl {
    pub key: String,
    pub kind: ConfigSlotKind,
    pub name: String,
    pub tested_value: Option<String>,
}

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"

Fields

key: String

The dotted TOML path this slot fills, e.g. backend.base_url, backend.auth.query_params.app_key, backend.auth.type.

kind: ConfigSlotKind

The slot kind (ConfigSlotKind — a closed vocabulary). REQUIRED: an entry omitting kind is a parse error, because a defaulted kind would silently mis-classify the slot.

name: String

The slot’s declared name — for a secret, the environment-variable name; for an endpoint, the variable the ${VAR} placeholder reads.

tested_value: Option<String>

The value exercised when the server was tested. None for identity-bearing slots (a secret), which structurally carry no value — ENFORCED by ServerConfig::validate, not just stated: a secret entry carrying a tested_value is refused, because that field is the one place a real credential could sit in a config that is served but never packed.
