}

Edge kind in the canonical causal graph (P1, docs/SYSTEM_DESIGN.md §9).

Variants

Next

Sequential causality.

Branch

Alternative execution path (fanout from evidence: call fanout, exception handlers, task spawn, runtime trace variants, declared).

Error

Failure edge to an error/exception handler or failure outcome.

Retry

Retry edge (back to the retried operation).

Fallback

Fallback edge to the degraded path. DEFERRED (§25): no reliable extractor evidence; not produced.

Async

Asynchronous dispatch.

Publish

Message/event publication.

Consume

Message/event consumption.

Join

Convergence of concurrent paths.

Return

Return/terminal edge. DEFERRED: subsumed by Next topology; not produced as a kind.

Timeout

Timeout edge. DEFERRED (§25): no reliable extractor evidence; not produced.

Compensation

Compensation/rollback edge. DEFERRED (§25): no reliable extractor evidence; not produced.

Read

State/data read.

Write

State/data write.

Transform

Data transformation. DEFERRED: subsumed by call-chain topology; not produced as a kind.

Validate

Validation/schema check. DEFERRED: no reliable extractor evidence; not produced.

Authorize

Authorization/policy gate. DEFERRED: trust-boundary analysis covers this; not a flow kind.

Cache

Cache lookup. DEFERRED: no reliable extractor evidence; not produced.

Invalidate

Cache/state invalidation. DEFERRED: no reliable extractor evidence; not produced.
