Struct HybridLogicalClock 

pub struct HybridLogicalClock {
    pub physical: u64,
    pub logical: u64,
}

Hybrid Logical Clock: (physical timestamp, logical counter) pair. Combines wall-clock time (microsecond resolution typical) with a per-node monotonic counter that breaks ties between events recorded in the same physical instant.

This is the K_cascade = 2 case of versioning: the outer level (physical) is coarse; the inner level (logical) refines tied physical timestamps. Same architectural pattern as Umbra prefix

• actual content, applied to time.

Fields

physical: u64

logical: u64

Implementations

impl HybridLogicalClock

pub const fn new(physical: u64, logical: u64) -> Self

pub fn now() -> Self

Construct from the current wall clock (microseconds since UNIX epoch), with logical counter starting at 0.

pub fn advance(&self, new_physical: u64) -> Self

Advance: increment logical counter (same physical) or jump to new_physical if larger. Used by an HLC source to record a new event.

pub fn merge(&self, received: &Self, local_physical: u64) -> Self

Merge with a received event: take max physical; advance logical if needed. This is the receiver-side HLC update.
