# Trace

Record the lineage or provenance of a target

Layer: Infrastructure · Category: Primitives

## Mechanism

A primitive for Provenance and Lineage. Attaches a chronological history log to a target entity. Each recorded modification appends a new immutable record to its trace, enabling auditability, debugging, and causal reasoning. Coverage may be partial: a trace guarantees the ordering and immutability of the records it holds, not that every modification reached it.

## Invariants

- Causality: Events must be logged in monotonic order.
- Immutability: History cannot be rewritten, only appended to.

## Failure modes

- Unattributable record: an entry cannot be tied to whoever produced it.
- Unbounded growth: an append-only log only grows. Expiry would contradict Immutability, so truncation or archival is a separate concern.
- Silent gap: a modification occurs without a record, so the absence of an entry is not evidence that nothing happened.
