Struct Properties 

pub struct Properties<'a> {
    pub time: String,
    pub user_id: &'a str,
    pub anonymous_id: &'a str,
    pub persistent_id: &'a str,
    pub api_key_tracking_id: &'a str,
    pub api_key_hash: &'a str,
    pub sdk_runtime: &'static str,
    pub cognee_version: &'static str,
    pub additional: AdditionalProperties,
}

Wide identity + version + sanitized caller properties under the properties view. Caller-supplied additional_properties are flattened into this object on the wire — Python spreads the dict.

Reserved field names — callers MUST NOT pass any of these in additional_properties (collisions produce duplicate JSON keys with implementation-defined deduplication on the consumer side): time, user_id, anonymous_id, persistent_id, api_key_tracking_id, api_key_hash, sdk_runtime, cognee_version.

Fields

time: String

MM/DD/YYYY of the current date — Python’s current_time.strftime("%m/%d/%Y").

user_id: &'a str

Identity tuple, repeated for analytics dashboards that flatten only the properties view.

anonymous_id: &'a str

Identity tuple, repeated for analytics dashboards that flatten only the properties view.

persistent_id: &'a str

Identity tuple, repeated for analytics dashboards that flatten only the properties view.

api_key_tracking_id: &'a str

Identity tuple, repeated for analytics dashboards that flatten only the properties view.

api_key_hash: &'a str

Backward-compat alias of api_key_tracking_id. Same value.

sdk_runtime: &'static str

sdk_runtime: "rust" — added per locked decision 2 so the proxy can distinguish Rust vs Python events without losing cross-SDK identity grouping.

cognee_version: &'static str

Cognee crate version — env!("CARGO_PKG_VERSION").

additional: AdditionalProperties

Caller-supplied properties, already sanitized by sanitize_nested_properties (URL keys hashed). Flattened into the parent object on the wire — Python spreads the dict.
