13 rules. Part II of the specification.

• ERR-1A node-level failure becomes an error output, not a thrown failurecore
• ERR-2Retryability is marked by presence, not by a booleanextended
• ERR-3A failure that is not node-level fails the runcore
• ERR-4An interrupt propagates unchangedextended
• ERR-5A node may stop the run successfullyextended
• ERR-6A node's output must be serializable throughoutextended
• ERR-7An error edge replaces the node's output with an error envelopecore
• ERR-8An error with nowhere to go fails the runcore
• ERR-9A run whose every failure was handled completescore
• ERR-10A routed failure activates error edges only, and only when it is currentextended
• ERR-11Retry is opt-in, in place, and immediateextended
• ERR-12Direct synchronous execution has no error-handling divergencecore
• ERR-13Every execution strategy routes errors identicallycore
