Struct EventSigningConfigWarning 

pub struct EventSigningConfigWarning {
    pub var: &'static str,
    pub value: String,
    pub reason: String,
}

U1-04: a single structured “this signing-config env var was ignored / fell back to the default” record, returned by SigningEventSink::from_env_with_warnings.

The composition root translates each entry into a StartupConfigWarnings::record call so CELLOS_STRICT_CONFIG=1 escalates signing misconfig to a fatal startup error instead of silently degrading to passthrough. Reviewer wave 2 (bebc77b) flagged that the legacy from_env shape only emitted tracing::warn! and therefore slipped through strict mode.

Fields

var: &'static str

Env var name that was misconfigured (e.g. CELLOS_EVENT_SIGNING_KEY_BASE64).

value: String

Operator-supplied value (best-effort; empty when only a companion var was missing). Never contains decoded key material — only the toggle / kid / opaque “<base64 …>” placeholders are stored verbatim.

reason: String

Operator-facing explanation of why the value was rejected.
