- one message class with a kind discriminator, not a receive per
message type: an actor handle is typed to one message class, so a
second receive compiles but is unreachable. chat/main.wo is the
precedent. Verified by fixture before amending
- Task 4's Files list omitted keypool.wo, which its step 4 edits
- clarified that the delete-then-insert ban targets using that pair as
an UPDATE; pruning an expired row is a plain delete and is required
