Latch 0.16.0

2026-10-04

Leave it. 🙅 The habits you want less of — booze, food, weed, money, anything — judged so that honesty is always the cheapest move. Migration 22 (vices, and activities.lag_days); nothing is judged from before a bad habit is added, and its first 14 days are a baseline: judged, never marked.

• A bad habit is a habit with a limit, not a second system: its name, icon and colour are an activity whose events are the days you kept it, so the calendar, the streak and the share-card tokens (streak_<name>, count_<name>…) come with it. Limits from a menu: a daily cap (0 = abstain), a weekly cap, a floor, dry days a week. Five starting points: 🍺 Booze and 🍽️ Food (read from SparkyFitness), 🌿 Weed, 💸 Spending and anything else (tapped in Latch).
• The ledger. From 18:00 until four hours after your wake hour the next morning, one question: is that everything? Closing it judges the day at once. A day you never close can be judged over the line, never kept — and it's a 🌫️ Dark day (2), which costs more than 🚫 Over the line (1). Where your count and SparkyFitness disagree, the higher one counts. A blank door under "that's everything" is a declared zero, and a dry day.
• Re-judged, never edited. A late tally, Sparky catching up or an amended ledger strikes the old verdict and writes the new one; a mark follows its verdict. A late ledger counts for the streak, earns no XP, and the Dark day stands.
• A day kept is +5 XP; a week kept is +15 XP and 10 minutes off if locked (leaveit.week_minutes). A confirmed day under the floor is never praise — the Handler asks.
• Passes: a planned exception declared before the day begins lifts that day's cap and takes it out of the week; warm 3 · firm 2 · strict 1 a month.
• Mischief: the two new marks are not held back on a recovery day — the likeliest cause of a short night after a day over the line is the day over the line. The lapse questions (lapse:over_line, lapse:dark_day) are seeded onto an existing library, once per kind.
• Streaks wait for an undecided yesterday (activities.lag_days): before you close the ledger, yesterday is pending, not failed — until its deadline, never past a decision.
• Health: new readings kcal, protein_g and drinks (alcohol grams ÷ 14), pushed by the sync from SparkyFitness and omitted on a day with no food entries. Ate and logged it stands down while a bad habit is judged on calories.
• API: GET /leaveit, POST /leaveit/ledger, /leaveit/tally, /leaveit/pass — numbers and states only.
