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.
messaging.js: a toast / CUSTOM ticker line is a string (its own msgid) or a shared/i18n.js msg(); frames keep
the Chinese `text` (older clients) and add `msgid` / `params`; config.broadcasts lines carry their `args`
(the client fills the localized broadcast template; the player name {0} is never translated). Templated call
sites send msg(): the grant toast 「X：获得Y」, the summon-range and terrain withdrawals, the 联防 line,
eliminated / left lines, the 远见 / 奇迹 stack payouts and the 维多利亚 hammers; game-data names go as dn().
The protocol stays backward compatible (new fields optional). Tests that captured m.toast's argument render
it with renderMessage. No gameplay change: golden unchanged.
