Struct AuditTag 

#[repr(C)]
pub struct AuditTag {
    pub org_id: u64,
    pub engagement_id: u64,
}

Two-level hierarchy for audit firm workload accounting.

Every K2K MessageEnvelope carries an AuditTag so that GPU work can be attributed back to a specific engagement — critical for per-engagement billing and tamper-evident audit trails.

AuditTag::default() returns { org_id: 0, engagement_id: 0 }, denoting an unspecified / system-level engagement. This is the backward-compatible default for single-tenant deployments.

Layout

Pod, Zeroable, AsBytes, FromBytes — safe for direct blit into GPU-shared memory. Rkyv-compatible for zero-copy serialization in message queues.

Fields

org_id: u64

Audit firm / organization ID.

Stable across all engagements belonging to the same organization. 0 = unspecified (default).

engagement_id: u64

Specific engagement / audit project ID.

Distinct per billable unit of work. 0 = unspecified (default).

Implementations

impl AuditTag

pub const fn new(org_id: u64, engagement_id: u64) -> AuditTag

Create a new AuditTag.

pub const fn unspecified() -> AuditTag

The unspecified / default audit tag ({0, 0}).

Used in single-tenant deployments and as the default for legacy APIs that don’t propagate audit information.

pub const fn is_unspecified(&self) -> bool

Returns true if this tag is the default / unspecified tag ({0, 0}).

pub fn to_bytes(&self) -> [u8; 16]

Returns the raw bytes of this tag (16 bytes, little-endian).

Used when stamping audit tags into wire-format K2K message envelopes.

pub fn from_bytes(bytes: [u8; 16]) -> AuditTag

Reconstruct an AuditTag from its raw byte representation.
