// test/sim/feedback5-cb4-pins.test.js — community reports of 2026-10-06 that this tree already answers, pinned (DESIGN
// §25.18; they pass on the parent commit — nothing changed for them):
//   item 6 「每局游戏开始展示的敌人类型（折射、飞行等等），实际出现波次在7到9波，而且每个最多三波，其余波次用特异类型填充」 — the
//     official type schedule (client RandomEnemyGenerater, research 08 §2.1; act2autochess specialEnemyRandomTypeDict count 3,
//     constData maxLevelCnt 15 / specialEnemyNum 3 / enemyTypeIdentifierToFillRandom 1): each briefing type owns 3 of the
//     15 round slots, SPECIAL (特异) the other 6, shuffled — R14 (leader) and R15 (hidden core) take slots too, so the 13
//     normal rounds hold 7–9 type waves, at most 3 per type;
//   item 35 「鸭爵策略的悬赏现在有时候会一波出现多只，比如多只鸭子」 — PRTS 下半/PRTS盟约记录 鸭爵 备注 「每回合将有0~2名敌人被
//     替换为上述敌人之一」: each player's wave gets 0–2 swaps (bands/meta.js duckReplace), each one of the four at random, so
//     two ducks in one wave is official (≈ 1 wave in 12 here); never more than 2 per player's wave;
//   item 29 「会移动的关底boss在各个地图的移动路线复核下是否正确」 — the only leaders that walk are 铳 and 卢西恩 (the 巨型单位 are
//     自缚: content/bosses.js SELF_BOUND); their official PATROL_MOVE checkpoints (level_act1autochess_h07_02 route 6,
//     act2 h07_05: (3,9) → (2,3) → (5,9), looped) are walked on every boss field of the season over walkable tiles only,
//     the pair's mirrored copy on the right half ((3,11) → (2,17) → (5,11)), and the loop never runs on to the goal;
//   item 38 「干员野鬃放在红门前两格的时候有概率会把怪顶出地图显示漏怪」 — not reproduced: her pushes (Battle.push → displace)
//     stop at the rect and at tiles a ground enemy cannot walk, so no pushed enemy stands off the map;
//   item 39 「锏能拉动10重的关底boss」 — not reproduced: a leader (tag boss) is never displaced (Battle._displaceable), and
//     her pulls (力度 1 / 2) move no weight ≥ 5 enemy (受力等级 ≤ −3, PRTS 推与拉);
//   item 47 「昆图斯占地少最左边和最右边两排」 — not reproduced: its hit area is PRTS' 4.95 × 2.95 up 1.0 — 5 × 3 tiles — and an
//     operator whose range reaches only its leftmost column hits it;
//   item 52 「最终boss跟原版相比攻击欲望感觉低了」 — every leader attacks at its data interval while a target is in range;
//   item 57 「囚犯敌人的解放状态联防时不应继承」 — a leaked prisoner re-enters 联防 as a new spawn (unite.js planUnite →
//     waves.js buildUniteWave: its key and spawn mods only), confined again (archetypes.js prisoner spawn); the freed look
//     the report saw was 普通 / 老练囚犯's red clip set drawn from the gate, fixed with the prisoners' forms (§25.14.1).
