jschoubben 90718ba7a3 fix9-7: a module that hears a seat's kept event is granted that stream's info (process.HearSeatEvents reads it); the forge bridge's bed holds the grant
Cause of the five forge bridge integration failures: HearSeatEvents (G §641) asks STREAM.INFO of the kept stream, which the grants part never composed.

Builds: design 47 G §641, A-19, §556
