On 战场#08 (act2 m04) the jump can land on tile_fence_bound (LOW, buildable ALL: deployable,
attacks, blocks no ground enemy) when the enemy stands in the 深水区 / on floor next to the
fenced blocks; the board draws the fenced region raised, the likely 「高台」 of the report.
No rule change (the official landing does not say it avoids 围墙). The test runs a melee
member's jump on every battle stage and enemy tile: low ground only.
