feedback5 WK: 自选编队 on the server — room.diy { picks } (lenient: illegal picks dropped, only malformed input is BAD_MSG; stored per session / seat; a match takes the picks its seat had at the start, a change during a match is for the next one; welcome lists diyKitted), PlayerState.diy with the player's data view (a slotted DIY slot is its operator for every rule: bonds from its factions, no 特质, the pick's skill and module, the slot's tier / price / merge), a per-player stock per slotted piece (8 at tier 5, 5 at tier 6 [ASSUMED]; never in the shared pool; none when every bond of it is banned), DIY pieces in that player's shop rolls and reward offers once the 调度中心 reaches the slot's level, battleInput diy, m.private.diy / diyBanned, prep scouting and results name the operator, 信标 never sends a 自选 piece to a teammate [ASSUMED]

The owner's decisions of 2026-10-05 (picks, slots, shop per player, bans); research 0.2.0 §2. Golden unchanged (no scenario slots a DIY pick).
Tests: test/match/diy-shop.test.js (9), test/lobby-diy.test.js (4).
