The trust boundary is zenmoney, not maven — they already hold his bank sessions. So the poller reads /v8/diff/ and writes totals as facts(kind=env, source=poll:zenmoney); core reads those back when he asks and never sees the token. internal/zenmoney sums transactions per currency over a window, skipping tombstoned rows and transfers between his own accounts, and refuses to encode a summary built from zero transactions. That refusal is the whole design: a failed or empty read writes nothing and leaves the last good total alone, because a zero recited as fact is worse than silence. No currency conversion either — a figure he can check against his bank beats one he cannot. Off unless configured, and the token is read from a FILE rather than a flag so it never lands in `ps`, in docker-compose.yml, or in shell history. Nothing about the money is search input, no tick rule reads the keys, and the log lines name keys, never figures. The live-credential half is BLOCKED: there is no zenmoney account or token here, so everything is verified against a recorded diff fixture.
