The watchman hears the lease write's events and the stream ASSIGNMENTS deleted

Browse Source 
ADR 0582 clauses 4 and 6 have mesh-grants say lease-altered and removal-failed "as a finding the watchman
raises". WatchmanHears, the one list its grant and its subscriptions come from, gains the seat mesh-grants'
three events and the advisory of ASSIGNMENTS deleted (which, with the controller's consumer deleted that it
hears already, clears a failed removal). Core subjects, read-only, no durable consumer.

Test: rows added to the watchman's subjects in TestTheCopiedComposerComposesAsTheControllers; no new function.

(issue 774, 774/S22)
