+# 012: Business production on play time
+
+2026-10-14, issue #6. Builds on decisions 003, 004, 010 and 011.
+
+## Decision
+
+- **Data** (`src/data/production.ts`): per business, its unit name, stock capacity, far-sale
+  bonus and one rate per upgrade combination: minutes per unit, value of one unit sold nearby,
+  and units one full supply bar makes. A rate applies only to exactly the upgrades it lists.
+  Values the source does not give are estimated by a stated rule and marked (decision 013), or
+  left out.
+- **Saved state** (version 4): `businesses` maps a property id to its bars in percent, the same
+  `Bars` that `BusinessBars` edits, including a supply delivery on its way. A business without an
+  entry starts empty.
+- **Production is continuous** on play time (`src/lib/production.ts`): stock rises and supplies
+  fall at a steady rate until stock is full or supplies run out. The game makes whole units, so
+  the stock count and value shown are rounded down to whole units. Bars stay in percent so the
+  user can resync them in the unit the game shows.
+- **Estimates are marked:** numbers resting on an estimated value are labelled "(est.)" and the
+  card explains the rule (decision 013). If there is no rate for the bought upgrades, or its
+  supply use is neither known nor estimated, nothing moves on its own: the card shows a "Not
+  tracked" warning and the bars can still be set by hand.
+  The value is shown whenever the rate is known.
+- **Deliveries during a stretch of play time** count from their arrival: the stretch is taken to
+  end at the wall-clock time it is reported, so production before the arrival uses the old
+  supplies and after it the new ones. Exact for normal ticks; for a long confirmed gap it is the
+  best guess LSOS has.
+- **Wiring** (`src/lib/production.svelte.ts`) adds every play-time stretch to each owned business
+  with a running rate.
+- **Cards start collapsed:** stock meter (units and percent), supplies meter, value (far sale first,
+  as it pays more; nearby smaller after it) and one play-time countdown, whichever comes first: "Full in" or "Supplies
+  out in" (the other cannot happen before it); "Out" is red. A delivery on its way shows too. "Edit" in the
+  card footer swaps the meters for `BusinessBars`, whose actions (Full, Supplies bought, Sold,
+  Raided, Undo) share one row. Which card is open lasts for the session only.
+- Bunker staff are taken to be on manufacturing only; research and the split are issue #33.
+
+## Why
+
+A rate per exact upgrade combination matches how the wiki lists them and leaves no room to
+guess an unlisted combination from the others. Continuous production keeps the maths and
+resync simple; whole units for value match what a sale pays.

+# 013: Marked estimates for missing game data
+
+2026-10-14, issue #6. Amends decision 004.
+
+## Decision
+
+- Where no source gives a value a tracker needs, it may be **estimated**, but only by a rule
+  stated in the data that derives it from sourced values (e.g. "as in the Bunker, where …").
+  Values with no such rule stay out, as decision 004 says.
+- The data marks which values of an entry are estimates and how they were derived
+  (`estimate: { fields, how }` on a production rate). Sourced values never carry it.
+- **Every number shown that rests on an estimate says so:** its label gets "(est.)", and the
+  card shows an "Estimate" note with the rule. A tracker with no value and no rule stays
+  "Not tracked" and does not move on its own.
+- Each estimate keeps an open `data` issue, so a sourced or measured value can replace it.
+
+First use (decision 012, issue #28): MC businesses without both upgrades. Supply use with
+equipment only is taken as with both (only equipment "stretches" supplies, per the upgrade
+text); without equipment, supplies last half as long, as in the Bunker. Staff only is taken as
+equipment only, as in the Bunker, where either upgrade alone gives the same rate.
+
+## Why
+
+A tracker that stops for the most common upgrade combinations is less useful than a clearly
+labelled best guess, as long as users can tell estimates from sourced values and planning
+around them is their choice.
