Two-sided capture (data_dumps/captures/battle_test/rng, 2026-06-04) showed the
receiver already reproduces uList-relayed deck fetches (Hoverboard) and turn
draws on its own shared stream, so the emitted spin=1 double-cranked and desynced
the clients by 1. Residual spin is ~0 for the current card pool. Reverts 63cb324
and 617714e; back to the prior correct spin:0 behavior.

Forwards the sender's deck-sourced summons/fetches to the opponent
(closes the spin-independent slice of direct-to-field summons). uList
coexists with the synthesized knownList in the same frame.

Verbatim uList relay shape + transform (deck-sourced summons/fetches),
mirroring RenameTargets. Not yet wired into the handler.

Choice/Discover-into-hand fanfares add a candidates-only token to hand; the
chosen cardId rides keyAction.selectCard on the generating play, not the
orderList add op. Record idx->chosenCardId at generation (candidate-membership
join) so the later play reveals the real identity via the existing
BuildPlayedCard path; forward {type,cardId} to the opponent and strip
selectCard for hidden (open:0) picks (pass through for open:1, provisional).
- KnownListBuilder.MineChoicePicks + StripKeyActionForOpponent (pure)
- BattleSessionState.RecordChoicePicksFrom (reuses IdxToCardId, no new state)
- PlayActionsBroadcastBody.keyAction + KeyActionEntry/SelectCardEntry
- PlayActionsHandler wires both; EchoHandler unchanged (picks ride the send)
Tests (TDD red->green): 8 KnownListBuilder + 2 dispatch + 2 conformance
(shape-locked to tk2_regular L151 generation / L193 reveal). Full suite 976/0.
