Interface IRCommit

Bounded call-graph annotation captured at commit-issue time. Optional — exporter omits the field when stack-trace capture is disabled (captureCallGraph: false on the export options). Schema 3 introduces this field; schema-2 IRs that never set it should either omit it or set undefined.

Node identifiers whose value changed as part of the commit.

Identifier of the graph instance this commit landed on. Required as of schema 3.

Human-readable label supplied to graph.commit(intent, …).

For commits issued by graph.hydrate(...), the GraphTime carried by the originating snapshot envelope. undefined (or omitted) on graph.commit(...)-issued records. The engine clock advances by exactly one tick per hydrate (the §3 monotonicity invariant); this field preserves the on-the-wire snapshot label so replay tooling can distinguish hydration events from regular commits without parsing intent.

The optional-or-explicit-undefined typing mirrors the published import('./types.js').Commit.originatedAt surface (#760): the engine's in-memory IRCommit row always-sets the slot to keep the V8 hidden class stable, while serialized exports may still omit the key on regular commits.

Lineage to the IRSubscribeCallback or other event that initiated this commit. Optional and presence-discriminating: a commit with originEvent set was emitted from a callback frame (an EPIC-2 CommitFromSubscribe candidate); a commit without was user-initiated. The string value is the id of the originating event in CauslModel.events. PR-B1 reserves the field on the wire and exports it as undefined until the engine gains in-callback commit instrumentation.

GraphTime at which the commit landed.
