`users_service` still write-then-emits at nine call sites. That is currently
INERT — `triggers.kind` has no `users` value, so the outbox emitter has no arm
for the source and drops the event — but it is the exact shape audit #6
removed from every other stateful service, and it would be reintroduced by
whoever adds a users trigger kind and finds the plumbing already there.
Note that this one does not even log the failure (`let _ = ...`).
Documented at the emit site, pointing at `atomic_write` and the write-path
invariant in CLAUDE.md.
