| 1 | ~~income chain~~ **DONE, and it did not unblock the phases** — `TradePointsToMoney` + difficulty ×1.1 landed at **25/25** on the `BnkEl` oracle (lane E1). But `ComputeBudget`'s **turn path** calls `ComputeOutput` with the system's own `Rts` sliders, **not** `ComputeMaxIncome` — a strictly larger function where the repair pass and the unspent-industry/terraform cascades are live. **The new item 1 is `ComputeOutput` on the turn path.** | `game/sim` | lane E1; `findings/subsystems/income-term.md` | P01/P02/P03/P05/P06, ~82 leaves, 2 RNG words |
| 2 | ~~wire `ShipCensus` + alliance mask into `BuildTurnRecord`~~ **DONE** (lane E2). T36 still blocked on two named things: the budget (item 1) and **ship construction** — a new blocker found by E2's *falsified* prediction (one census leaf short by exactly one destroyer on both pairs; no phase we run builds a ship). | `app` | lanes D2/A2 | +24 turnstats leaves when item 1 lands |

The gate is `AFlags`, not `VFlags`/`EFlags`, and all three agree on nearly every corpus system so the wrong one *looks right*. Remainder: `TShn` (10/pair, gate proven NOT `AFlags`, watchpoint specified), `rcex` (6/pair, unexplained). | `game/sim` | lane E3 | **51 leaves closed** |
