Up to 0.1.1 only the 技能就绪 trigger required a landing tile that covers the target; the 10 s idle trigger took
raidTile's fallback (a tile that covers nothing), so a member with nothing reachable hopped every 10 s between useless
tiles and never went for a second ground enemy it could have hit. Now both triggers walk the candidates in the existing
order (own field first, most advanced first, at most 8) and jump to the first one with a covering tile; none -> the
member stays, its idle time keeps counting and the 0.25 s poll looks again. [ASSUMED]: the official text only says
"再部署至一名地面敌人周围".
raidTile now enumerates only the tiles a range offset leads back to from the enemy's body (same choice as the old
25-tile scan whenever a covering tile existed: 200 000 random cases), and a player's members share one sorted candidate
list per poll (rebuilt after a jump), so a search that finds nothing stays cheap: +5.8 us per tick on the heavy boss
field with 18 members that never reach anything, against +5.5 us for 0.1.1 (the plain requirement on the old scan:
+29.6 us). Tests: two "突袭 #51" cases in test/content/bonds_addon.test.js.
