mesh/merge-gate pass: builds new: modules/betterbird, sent nowhere; no bus step; every machine composes with the change as it did without (4 of 4 compose)
mesh/repo-check pass: its merge-check.sh passed, each part in its toolchain: merge-check.sh (go), merge-check-typescript.sh (typescript)
mesh/delivery superseded: a newer head of the same pull request
betterbird: a module for the mail and calendar client, so its windows and preferences can be seen and declared (hq issue 345)
A calendar reminder showed as a transparent, empty window on shanks and no tool could say which
window it was or which preferences Betterbird ran with. The module owns one file, the user.js its
setting prefs fills, which its tools place whole into the profile Betterbird uses and never over an
operator's own; it reads named preferences without credentials or accounts, restarts Betterbird under
the user manager so its output reaches the journal, checks what it promises, and shows a reminder on
demand from a throw-away profile so a fix can be proved without the operator's calendar. No package:
betterbird-bin is the AUR's.
