feedback5: merge CB1 — community reports (bonds / strategies / items): a pair of colds on an enemy becomes the freeze and leaves no cold (the 谢拉格 wind no longer freezes for good), a 复活 (埃芒加德's 命结之秘, M3茧甲) is a knock-out and an immediate free redeploy where the operator lies (砾's and 瑕光's 被击倒时 / 部署时 layers fire), 佩佩's special refresh is paid, the result card hides the layers of 调和 / 协防干员 / 独行 / 绝技, the 炎佑 keeps off 外勤医疗's slot, 凯瑟琳's 定向投放 offers every shop item; 烛煌's 绝处重燃 before the hammer's lock and the 寻呼模块 / 简易通讯机 tier cap kept as they are (the owner's decisions of 2026-10-07); §25.15 → §25.21 (§25.15 is the shortcuts'); golden: vs feedback5 CB1's own rules — roster-005/009/010/012/014/015/016/018/026/029/031/033/036/040/042/046/047/049, bond-egirShip-high, bond-indomShip-low, bond-kjeragShip-high, bond-maniShip-high, bond-raidShip-low, bond-steadShip-high, bond-suntShip-low, boss-boss_2/3/4/6-pair, hidden-boss_8/9/10-pair, standin-07, matches solo-FUNNY-1, solo-NORMAL-1, solo-HARD-1, solo-ABYSS-1, coop3-ABYSS-5, coop4-FUNNY-6, coop4-ABYSS-7; vs CB1 what feedback5 changed since its base (CB2, CB3, CB4, CB5) plus roster-014

Conflicts resolved by hand:
- server/sim/content/items/battle.js: CB3 had extended `revivedInPlace` (an in-place 复活 restarts a deploy-timed
  skill, item 44); CB1 replaced the in-place revive by PRTS's form — `reviveNow`, a `death` hook that redeploys the
  operator at once, free, where it lies — and removed `revivedInPlace`. CB1's side is kept: its redeploy resets the
  skill, so an `activateOnDeploy` skill starts anew by itself; CB3's tests (test/sim/feedback5-raid-revive.test.js:
  the jump at once after M3茧甲 / 埃芒加德, the window back to full, 砾's fresh barrier) pass on it unchanged. Their
  header, bonds_core's comment, DESIGN §25.17.5 say so.
- docs/SIM.md, docs/design/engine.md: CB1's `fatal` rows (the 复活 are `death` hooks now); the `death` rows also say a
  deploy-timed skill starts anew (§25.17.5).
- data/choices.json: no conflict; `node tools/build-data.mjs --offline` on the merged tree rewrites all 15 data files
  byte-identically, and the JSON compare with feedback5 shows only pools.pool_equip_kathe.maxTier removed (CB1).
- docs/history/0.2.0.md: CB1's section renumbered §25.21 (its §25.15.1–10 and two self-citations; no citation of it
  elsewhere), placed last; the owner's decisions of 2026-10-07 on items 5 and 45 recorded there, in the intro and in the
  two pin tests' headers (feedback5-blaze-hammer, feedback5-cb1-pins).

Golden: solo-FUNNY-1 (outside CB1's list) has 6 埃芒加德 revives and 85 freezes on feedback5's path (instrumented).
roster-014 differs from CB1's own digest by 玛恩纳's 无动于衷: CB3's rule (every enemy damage instance) answers the
萨卡兹枯朽战车's pollution that hits a 卡西米尔 operator in CB1's timeline — with that counter limited to attacks the merged
roster-014 equals CB1's digest exactly (checked).

Gate: non-browser suites 5021 / 5021, npm run golden ok, test/golden.test.js 9 / 9, lint 0 errors, check:imports ok,
typecheck ok.
