feedback5 WE: 联防 is played on its own map, the escaped template level (GitHub #41, item 3) — act2autochess constData escapedBattleTemplateMapSinglePlayer / MultiPlayer = level_act1autochess_escaped_single / _multi name the level of the 联防 battle, and its map is the field: two road halves (cols 3–9 and 11–17, rows 9–12) joined at col 10, no water, crates or devices (until 0.1.3 the round's stage, opened to both halves). tools/build-data.mjs builds both into data/stages.json after the 11 battle stages (kind 'unite', helpers 1 / 2, weight 0, inactive, no modes, the name 联防阵地（N名玩家） the remake's own label [ASSUMED]; validation ties config.unite.templates to them); regenerated offline, a JSON compare shows only the two added records. unite.js uniteStageId picks the map of the helper count (escaped_single's routes enter at col 10, escaped_multi's at col 18 through (9,10)); match/unitePhase.js fields the 联防 battle on it (the round's stage only with data that lacks it); each helper on its prep tiles, the first of two shifted 8 columns onto the right half as before (the official halves; player_map_lr_offset 8). Client: screens/game.js draws the shown field's own map and restores the board's on leaving it (a 2-line change in a file of the R5 split; render/app.js enterBattle already loads m.field stageId); the dev mock's 联防 follows. The 联防 BGM (PR #110) is unchanged. Tests: test/match/feedback5-unite-map.test.js (both combat modes, 1 and 2 helpers, degraded data), test/data.test.js, test/render/tiles.test.js. Docs: DATA §12, META §4, DESIGN §3, PLAYING §5. Golden: fields unite-1 / unite-2 (the battle's stage → the 联防 map) and the 6 co-op match scenarios with a 联防 round (coop2-NORMAL-3, coop2-HARD-4, coop3-ABYSS-5, coop4-FUNNY-6, coop4-ABYSS-7, coop2-NORMAL-8-serverrun); roster / bonds unchanged (tools/golden.mjs leaves the 联防 maps out of its stage list)

 某回合**有人漏怪、又有人完美作战**（全歼且无漏怪）时触发：最多 2 名完美作战的队友带着自己的阵容（与官方相同，只保留作战结束时的生命比例和技力：作战结束时还开着的技能在联防开场是关着的，技力是开技能后剩下的值，通常为 0；召唤物只保留技力；作战结束时已被击倒的干员在原位倒地（阿戈尔的开场吞噬仍把它当作站着的干员计算标记与基础攻击力、阻挡数，之后它照常退场），按官方的「强制退场」以完整的再部署时间重新倒计时，时间到且部署费用足够后照常再部署——联防较短时可能来不及再部署；机变「征召」这类开战时生效的再部署时间减免同样计入），迎击其他玩家漏掉的全部敌人。盟约层数按本回合自己作战结束时达到的层数（即盟约栏显示的层数）计算，联防中不再叠加层数；这些层数在结算时只计入一次。
 
 - 参加者按官方规则挑选：场上单位最多 > 有已激活的盟约 > 未倒下的单位最多 > 座位靠前（与 LP 无关）；两人参加时，排在前面的一位（再比较激活盟约的层数总和）在右半场「率先迎敌」。
+- 联防在官方的**联防专用地图**上进行（与官方相同，不是本回合的战场）：一整片道路，没有水池、箱子、装置等地形；干员按休整期的位置站好。一人协防时敌人从中间的入口进入左半场；两人协防时敌人从最右侧进入，先经过右半场，再穿过中间进入左半场。
 
 - 只有完美作战的队友能参与联防；联防中**盟约不会叠加层数**。
 - 联防中击杀悬赏敌人，资金归击杀者。
