Filbert approved on #1596, comment 28251. Mos gave the go for the one
public/ line, bus.js's UNSEEN pattern (decision 123, sage-0140).

Sage's gate rerun on 3a1e11b83 with rows 85, 102 and 103 applied,
Docker up: node suites bus 128, business 67, cli 165, control-board
124, conversation 182, discord 178, harness 73, ledger 78, mosaic 69,
