Struct MemoryWrite 

pub struct MemoryWrite {
    pub id: String,
    pub subject: String,
    pub purpose: String,
    pub expires_at: Option<Timestamp>,
    pub access_retention_seconds: Option<u64>,
}

Where a runtime memory write lands.

Security metadata is intentionally absent. StepCtx::remember derives trust, provenance and sensitivity from the Tainted<Value> being stored, so an untrusted model result cannot be promoted by constructing metadata that says otherwise.

Fields

id: String

subject: String

purpose: String

expires_at: Option<Timestamp>

access_retention_seconds: Option<u64>

Implementations

impl MemoryWrite

pub fn new( id: impl Into<String>, subject: impl Into<String>, purpose: impl Into<String>, ) -> Self

pub const fn expires_at(self, at: Timestamp) -> Self

Expire this memory from fresh recall at a deterministic instant.

A hard ceiling: a sliding window set beside it may collect the memory earlier, and no touch carries it past this.

pub const fn retain_after_access(self, seconds: u64) -> Self

Keep the memory for this long after each explicitly journaled recall.

The window opens at the write itself, so an untouched memory is collected seconds after it was stored rather than kept forever waiting for a first touch — and it never extends past an expires_at set beside it.
