Struct RecallTurnMetadata 

pub struct RecallTurnMetadata {
    pub selected_memory_ids: Vec<MemoryId>,
    pub source_classes: Vec<MemorySource>,
    pub rank_reasons: Vec<RankReason>,
    pub retained_bytes: u64,
    pub retained_tokens: u64,
    pub dropped_bytes: u64,
    pub truncation_count: u32,
    pub recall_latency: Duration,
    pub withheld_count: u32,
    pub skipped_count: u32,
}

Spec §10.4 explainability metadata retained for the current turn’s accepted recall. Counters, identities, and durations only — bounded by the §10.3 record limits; never memory content. Rendered for /memory why by RecallTurnMetadata::render (task B5).

Fields

selected_memory_ids: Vec<MemoryId>

Selected memory identities, in contribution order.

source_classes: Vec<MemorySource>

Source class of each selected record (parallel to the IDs).

rank_reasons: Vec<RankReason>

Rank reasons across all selected records (flattened).

retained_bytes: u64

Bytes of rendered contribution retained after bounding.

retained_tokens: u64

Conservative token estimate of the retained rendered text.

dropped_bytes: u64

Bytes dropped by bounding (records + rendered block).

truncation_count: u32

Truncated-record count (provider-reported, floored by the host’s own per-record observation).

recall_latency: Duration

Wall-clock recall latency for the accepted call.

withheld_count: u32

Records withheld by disclosure policy (counted, never named).

skipped_count: u32

Candidates considered but not selected.

Implementations

impl RecallTurnMetadata

pub fn render(&self) -> String

Human-readable /memory why text (task B5, spec §10.4). Mirrors MemoryContextStatus::render: bounded metadata only — selected IDs, source classes, plain-words rank reasons, byte/token accounting, truncation count, latency, and withheld/skipped counts — never memory body content.
