Struct MemoryObservabilityEvent 

pub struct MemoryObservabilityEvent {

    pub event: &'static str,
    pub outcome: &'static str,
    pub session_id: Option<String>,
    pub turn_id: Option<String>,
    pub project_digest: Option<String>,
    pub provider_id: Option<String>,
    pub mode: Option<&'static str>,
    pub record_count: Option<u32>,
    pub retained_bytes: Option<u64>,
    pub retained_tokens: Option<u64>,
    pub dropped_bytes: Option<u64>,
    pub duration_bucket: Option<&'static str>,
    pub withheld_count: Option<u32>,
    pub skipped_count: Option<u32>,
}

One spec §15 metadata-only observability event. Every field is drawn from the §15 ALLOWED list — session/turn correlation IDs, the host-derived project digest identity (never a raw project path), provider ID, mode, record counts, byte/token accounting, duration buckets, disclosure/withholding counts, and a typed outcome code. The struct has no field that could carry user messages, memory bodies, raw tool results, credentials, or provider error text, so the §15 DISALLOWED list is excluded by construction, not by discipline.

Fields

event: &'static str

Spec §15 event name.

outcome: &'static str

Typed outcome code (e.g. enabled, injected, timeout).

session_id: Option<String>

Session correlation ID.

turn_id: Option<String>

Turn correlation ID.

project_digest: Option<String>

Host-derived project digest identity — never the raw project path.

provider_id: Option<String>

Context-provider identity.

mode: Option<&'static str>

Spec §6.1 mode vocabulary.

record_count: Option<u32>

Selected record count.

retained_bytes: Option<u64>

Bytes of rendered contribution retained after bounding.

retained_tokens: Option<u64>

Conservative token estimate of the retained rendered text.

dropped_bytes: Option<u64>

Bytes dropped by bounding.

duration_bucket: Option<&'static str>

Coarse recall-duration bucket ([duration_bucket]).

withheld_count: Option<u32>

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

skipped_count: Option<u32>

Candidates considered but not selected.
