Type Alias ReactionOptions

Only react when this predicate returns true.

Transform the source command into the target command's target.

Transform the source command into the target command's payload.

Allow sourcePattern to match targetAction — i.e. the reaction fires on its own dispatch. Refused by default, because the loop it creates is bounded only on a sync bus:

• Sync bus: listeners fire nested inside dispatch, so MAX_DISPATCH_DEPTH halts each chain — 16 recursive dispatches and a logged VC_CORE_MAX_DEPTH per matching action. Degraded, bounded.
• Async bus: listeners fire post-settle, so each cycle is a fresh top-level dispatch with the depth counter unwound. Nothing bounds it — a self-sustaining infinite loop running handlers, plugins and (with a bridge installed) HTTP requests forever.

Opt in only alongside a when guard that can actually terminate it. The maxHops cap still applies.

How many reaction hops a single originating command may trigger before the chain is refused. Catches INDIRECT cycles (A→B, B→A), which no install-time check can see. Default: 8.
