+**Corrections from the B1 live trace (2026-09-08, sots-engine `docs/B1.md`, 4,623 traced +
+4,437 compared calls on `ref-turn2.sav`):**
+
+- The out parameter is **`int[22]`, not `int[25]`**. It is a `Budget` object:
+  `{ int slot[22]; std::vector<{Tech* node, int points}> researchAlloc @+0x58; int overBudget @+0x64 }`.
+  The three words after slot 21 are the vector's `{first, last, end}`; they grow by exactly one
+  8-byte element for a player with `ResT` and stay `{0,0,0}` otherwise. (What was read as
+  "[22]..[24]" is that header.)
+- **`[9] researchMoneyKept` is written inside the `if (ResT)` branch**, together with the
+  `researchAlloc.push_back`. A player with no research target still gets `[16] researchMoney`
+  and `[17]/[21]` research points, but `[9]` stays 0 and the money is never subtracted from the
+  net. Independent evidence: player 0 of the reference save has no `ResT`, and its End Turn
+  moves `Sav` 289,688 -> 532,369, i.e. `+[1] 239,785 +[5] 2,896` with nothing deducted.
+- `GetDifficultyMods` rows, measured: **AI (`isAI && !NPC`) = {maintenance divisor 3, research
+  multiplier 1.5}; human/NPC = {1, 1}** for this game (AI Normal, econ/research 100 %).
+  `[8] = Maint / ftol(divisor)` confirmed at 500->166, 1000->333 (AI) and 1000->1000 (human row).
+- `p+0xf9` is the AI gate as described: player 7 is `isAI && NPC` and takes the human row.
+
 So the "budget sliders" are `ResRate` (research share of net) and the `Nexp` entries; construction is not a slider —
 it is whatever the build queues demand up to `avail`. The UI pie chart (`PIECHARTCOLOR_INCOME/COST_FLEETS/COST_RESEARCH/
 COST_RESEARCH_AID/COST_FLEETS_QUEUED/COST_FLEETS_TOTAL`) is drawn from this same array.
