-      **One Revenue for every train that clears your section.** Worth exactly **+5.40 a game** —
-      departures run at 5.40 and each pays 1 — taking the bot from 2.7 to 8.0 mean, median 0 → 6.5,
-      wins 2/200 → 14/200. It more than doubles the score on its own and pays for traffic the player

+      **~~One Revenue for every train that clears your section.~~ Now: one Revenue to EVERY player
+      when a train completes its run.** Jesse's revision in v0.4.2. The first version paid the Office
+      a train departed, which on a five-Office railroad paid five separate times for one train and
+      paid most to whoever it passed first. It pays once now, when the train runs off the end of the
+      Division, and it pays the whole table — getting a train the length of the railroad is the
+      shared achievement, and every Office it crossed had to clear it.
+      Solitaire is nearly unmoved (7.0 → 7.3 mean over 200 games) because one player's departures and
+      completions run at almost the same rate; **in a multi-player game the shape is completely
+      different** and needs measuring once multiplayer exists — N players × 1 per completed run
+      against the old N payments per train. **The victory-target question stays live**: 20 over 5 Days
+      is still reachable largely on traffic, which is either the intent or an argument for raising it.
+- [ ] **BOT DRIFT ACROSS THIS RELEASE — four measurements, all for the rebalance pass.** Recorded
+      together so the pattern is visible rather than four relaxed thresholds nobody adds up:
+      - **Switching work down ~16%, 1.76 → 1.48 productive acts a game** (400 games), because an
+        expedited train now stands at the Office for a Stage instead of passing straight through, and
+        a train on the A/D track and the Office square is in the crew's way. That is the change doing
+        its job rather than a fault — but it is drift. Collisions also went 0.05 → 0.06 and the worst
+        game went −3 → −9, same cause: the Office fills up. **Separately, the `work > 2` floor that
+        caught this had never actually been met** — it read 2.16 at 150 games and 1.76 at 400, so it
+        was passing on which seeds the sample happened to include. Now 400 games and a floor of 1.2.
       - **Track laid badly, 7% → 15%** of pieces butting a card that cannot accept them. Forced to
         shed on turn one, the bot would rather lay a piece than discard it; a player would discard
         the ones with nowhere good to go. It also means the district-size gain from the new deal is
