Final three clusters:
- RoomParamKey: copy Wizard.RoomMatch/RoomParamKey.cs verbatim (UriNames/WatchUriNames
static dicts keyed by PlayerController.ROOM_URI + PlayerControllerForWatching.
SEND_PARAMETER — both now real enums).
- CardChooseTask: copy the TwoPick/CardChooseTask.cs (TaskManager `using`s .Arena.TwoPick,
not .Competition — copy_loop had only landed the Competition twin).
- SetCardNumLabel CS1739: decompiler param-name artifact — the local fn's 3rd param was
recovered as `flag` but call sites pass it named `isRed:`. First DP5 tracked patch:
Engine/UICardList.cs edited (flag->isRed, zero logic change), recorded in
Patches/ + manifest patched=1 (drift-clean).
M1 exit criteria met: `dotnet build SVSim.BattleEngine` = 0 errors, no Unity ref in csproj,
check_drift clean. Session 7: 198 -> 0 across waves 7a-7k.
