What your assistant is told

Per-habit status for ONE local day: whether each habit was scheduled, whether it was met, the amount logged vs its target, and the current streak. date is YYYY-MM-DD in the user's LOCAL calendar; tz buckets the day locally (check-ins are stored in UTC) and defaults to the zone on their profile, so pass it only to override that. Use this to answer "how did I do today?" and to see what's still outstanding. For today, each habit also carries next — when it is next due — so "when can I take the next one?" has an answer you should not work out yourself. Instants are UTC; say them in the user's local time. - reason: "time" — a planned time. When at is later than plannedAt, the habit's minimum gap pushed it ("your 20:00 is now 21:00, eight hours after the 13:00 one"). - reason: "gap" — no planned time; it can be done again from at. - reason: "dropped" — the gap pushed today's next time past the end of the day, so today no longer expects it. readyAt is when the gap since the last counting entry runs out.
