 - "不同" (distinct): operators are identified by their normal chess id (chessNormalIdLookupDict maps *_b -> *_a), so a normal and an elite copy of the same operator count once. Exception: 助力 3-member tier counts operators that differ in name OR elite state (PRTS 修正). 独行 is only broken by 2+ DIFFERENT 独行 operators (PRTS 修正).
 - 调和 (maniShip): while active (>=1 调和 operator on board) every core bond (isPower=true) gets member count +1 (a single +1, not per 调和 operator), and 调和 operators receive the effects of every active core bond as if members. [ASSUMED: the +1 applies only to core bonds that already have >=1 real member on the board.] "炎佑" does not include 调和 operators' stats unless they are also 炎 (PRTS).
 - Item 变形同构体 (chess_item_6_09_e, canGiveBond) worn together with a bond item (trapChessData.giveBondId) makes the wearer an extra member of that bond. 14 bonds have such items; 灵巧/远见/奇迹/投资人/助力/调和/协防干员/独行/绝技 do not.

 - `PRESET` (74): 特许干员 — all 4★ (19) / 5★ (48) and 7 non-gacha 6★ (伺夜, 信仰搅拌机, 歌蕾蒂娅, 魔王 x2, 流明, 溯光星源); usable even if the player does not own them.
-- `NORMAL` (55): all 6★ gacha operators. If the player owns the operator, their own copy is used; otherwise a friend-support copy (up to `borrowCount`=20) or the **backup** operator: `backupCharId` is a special non-obtainable stand-in (预备干员 4★ `char_600..607` or 6★ "罗德岛特派高级干员" `char_608..617` = 郁金香/Sharp/Mechanist/Stormeye/Pith/Touch/Raidian/Misery/领主·Sharp) with `backupCharSkillIndex`. Backups keep the chess's bonds and 特质. **For the fan remake: always use the real operator** (no ownership system); backup data is kept in JSON (`backup`).
-- `DIY` (4): `chess_char_5_diy1/2_a`, `chess_char_6_diy1/2_a` — 甄选 slots (2 in tier 5, 2 in tier 6). `diyChessDict` = `TIER_6` means the player may put in **one of their own 6★ operators** not already in the pool; bondIds = [] and garrisonIds = null, so it gets the fallback bond `emptyShip` (协防干员) and no 特质. Status same as tier 5/6 chess. Remake suggestion [ASSUMED]: either drop DIY slots or let each player pick any 6★ from a curated list before the match.
