  "handle": "Trace",
  "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.",
  "gloss": "Record the lineage or provenance of a target",
  "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."
  ],
  "invariants": [
    "Causality: Events must be logged in monotonic order.",
    "Immutability: History cannot be rewritten, only appended to."
