GitHub #385 / PR #387 by @zasx77771. The prep scout sends the hand and the 临时整备区 as units, and ownerBoard put every
op unit on the popup's synthetic board, so the popup marked bench operators 在场 and its 成员 header disagreed with the
server's ring (炎: ring 1, header 3; 远见: ring 2, header 3 with the temp copy).
The scout's units now carry `area` 'board' | 'hand' | 'temp' (the server tags from PR #387; the tag survives the
boss-half remap, the row does not). ownerBoard sorts them into board / hand / temp instead of dropping the bench as
the PR did: dropping the hand would break the bonds that count the 整备区 (投资人 / 远见 / 奇迹 — a hand-only 远见
member: ring 1, header 0). bondMembers / memberHeadCount then count exactly as the player's own popup: hand = owned
and in hand, temp = owned only. A unit without an area (battles, older servers) stays on the board.
Docs: PLAYING.md's 观看谁 paragraph (the bench is listed in prep); comments in bondStrip.js / game.js.
Tests: test/ui/watch-bonds.test.js (36; 2 fail on the parent), test/match/prep-bench.test.js +
feedback5-boss-pair-prep.test.js (area tags; 4 fail on the parent). Golden unchanged (views only).
The own half was already the official one (the right-hand player on the right half with the
right_boss_*_camera_param camera, its layout mirrored col c -> 20 - c with RIGHT <-> LEFT, so its operators
face the leader as before: research 09 §1.2, DESIGN §15); the partner's half stood empty and nothing framed
the pair.
Server: in a boss round's prep m.private.bossMate { playerId, side, units } = the partner's board as UnitInfo
on its half (Match.bossMateView, finalAssault.js bossFieldPlacement); markPrivate marks the partner's
m.private with the mover's, so it follows live; a scout of either player (Match.prepFieldMeta) carries both
halves (`mate`), and its signature covers the partner's board.
Client: render/app.js syncMates draws the partner's units read-only ('m:<uid>' views: never picked, dragged
or swept with the own pieces) and the whole boss field is lit; the team panel frames the pair's avatars
(gameLogic teamFrameIds: the players still in by seat, two by two, as prepCamera — the boss field in the
fight) from the round start through the Final Assault / Hidden Core, with the official ui/battle
bg_team_border tinted the autochess green (#4ed8af; a plain ring without the local art); none for a lone
player, an eliminated player, a spectator seat, or 联防.
Overlap with PR #191 (same-field frames, issue #190; not merged): it published m.public bossPairing and
framed the partner alone in gold, 联防 included, plus a banner naming the partner; here the pairing is read
as the prep camera already does, both avatars get the official green frame, boss rounds only.
[ASSUMED] the partner's bench is not shown; one frame per avatar.
Golden unchanged. Tests: test/match/feedback5-boss-pair-prep.test.js (new, 4), the item 55 test now checks
the scouted player's own pieces (the partner's stand on the other half); SP_E2E
test/ui/feedback5-boss-pair.e2e.test.js (new, 2: both halves and the frames in prep and fight; item 55's
eliminated guest on the boss field with the leader). Docs: design/client.md §10 / §15, design/network.md,
PLAYING.md.
