No dominant style: a lone bot wins 24–26%, except balanced among farmers at 29% (±1.4 pp at 1,000 games, so a real but small edge; the style spread target, ≤ 6 pp, holds). More aggression makes games longer and less close: all-aggressive is the only heuristic lineup over the p90 limit (127 min) and at the edge of the rivals target (0.50); fights cost stripes both ways (+0.45 / −0.43 per turn) and aggressive bots also pay more Fatica (−0.13).

  - [x] 6.4.0 Board draft 2 (drafted as `board/drafts/quadrant-2.txt`, now `board/quadrant.txt`), built for Fatica on crossing. Principles approved by the developer: Fatica as tolls on short routes, fewer Fatica, Allenamento away from the Safe Rooms (covers 6.5), validator / Tatami 30–40% / 11-step walk / tunnels kept; judged on casual minutes (≤ ~93, i.e. v0.7 casual + 10) and heuristic bots paying some tolls.
    - Method: walls of draft 1 kept (approved layout); only square codes changed. Route analysis showed every square on a shortest Safe Room → Dojo walk has a detour of at most 1 step, so "detour 2–4" is not reachable without wall changes; tolls were placed by measured traffic instead (bots' walks per square, home players vs visitors, on the board without Fatica). Home players load the row-3 corridor and the inner Dojo approach (5,5); visitors load the ring next to the Dojo.

Draft: replace every Fatica and some Allenamento with it (start: all F plus about a third of A, keep the square mix inside the validator's Tatami range).

  - [x] 6.4.2 Option 1, Fatica on crossing: `RulesConfig.fatica_on_crossing` — each Fatica square entered during a move costs 1 stripe, **1 in total per square whether or not the move stops there** (developer, D33); stopping on it adds nothing more. Engine: apply in `_walk` per square entered (not on teleports / relocations, which never walk). Bot: count Fatica crossed in `_path_score`. Likely needs fewer Fatica squares; test on the current board and on a draft with fewer F. Done as the baseline rule (D36): engine `_step` / `_path_choices`, bot `_path_score`, tests; measured on the current board in the 6.1 re-baseline.

Original step: after 6.4, if the own-quadrant share of square income is still above 60% (baseline: 71%), move Allenamento squares away from the Safe Rooms in a board draft (`dojo sim --quadrant board/drafts/...`) and compare. The board must still pass `dojo board validate`.
