One Sentence Summary

A developer using event_engine can now define an event in the rules file before any handler exists for it, without the app failing to boot.

ACs Covered

• A host can give an event the rule unrouted in its rules file to define the event before anything handles it.
• An event ruled unrouted passes the boot-time rules check instead of failing it.
• Emitting an event ruled unrouted raises the unroutable event error instead of being dropped or looking up a processor named unrouted.
• The README, the changelog and the develop guide file that gets installed into host apps describe the unrouted rule.

Decision Log

How does a host mark an event that is defined but not routed yet?

With the rule value unrouted in the rules file, chosen over treating a blank rule as allowed, so leaving an event out by mistake still fails the boot check.
