Struct QuerySubjectRequest 

pub struct QuerySubjectRequest {
    pub agent_id: AgentId,
    pub subject: String,
    pub valid_at: Option<DateTime<Utc>>,
    pub as_of_tx_time: Option<DateTime<Utc>>,
}

Request to retrieve the resolved belief for every predicate stored under a subject.

Returns one SubjectFactEntry per distinct predicate that has at least one claim satisfying the as_of_tx_time cutoff. Each entry is the same fold result that query_memory would produce for that (subject, predicate) pair under the same valid_at / as_of_tx_time — the existing fold/disposition logic is reused, not reimplemented.

Fields

agent_id: AgentId

The agent whose memory is queried.

subject: String

The subject for which all predicate beliefs are returned.

valid_at: Option<DateTime<Utc>>

Optional: query as of a specific valid-time instant (valid-time axis).

When set, the fold selects the claim whose valid-time window contains this instant. When None, the backward-compatible behaviour is used (as_of / now drives both axes).

as_of_tx_time: Option<DateTime<Utc>>

Optional: query as of a specific transaction time (bi-temporal tx-time axis).

When set, only claims whose tx_time <= as_of_tx_time are visible. When None, the full current view is used.
