Function write 

pub async fn write(
    state: &ServerState,
    ctx: &AuthContext,
    action: &str,
    run_id: Option<String>,
    config_fingerprint: Option<String>,
    result: &str,
)

Available on crate feature serve only.

Build + persist one audit record (best-effort). A backend write failure is logged at WARN and swallowed: auditing must never fail the underlying action, but the failure is made visible rather than lost.
