The translation middleware decrypts + msgpack-decodes the request body
into the action's first-parameter type, then re-serializes that DTO to
JSON for the auth handler to read. Phase 3's DoMatchingRequestDto and
RankBattleFinishRequestDto didn't inherit BaseRequest, so viewer_id /
steam_id / steam_session_ticket were dropped during the msgpack → DTO
→ JSON pivot — the auth handler then saw a body with no auth fields
and 401'd every request.
Fixed by making both DTOs extend BaseRequest, mirroring the Phase 2 TK2
DoMatchingRequest pattern.
Also added [FromBody] BaseRequest parameters to the previously body-less
actions (AiStart × 2, ForceFinish, AddClientLog, GetLatestMasterPoint).
The translation middleware explicitly requires at least one parameter
to bind the decrypted msgpack body (see L130-136 of the middleware);
without it the request would throw InvalidOperationException at runtime.
Tests updated to post viewer_id / steam_id / steam_session_ticket
placeholder values in the request body, matching the existing TK2 test
pattern.

AiStartInternal builds the self MatchContext, picks a bot from
IBotRoster, projects to the AiBattleStartResponseDto with camelCase
wire keys (sleeveId, emblemId, ... — see ai-start.md). turnState=0
(player first) is the safe default per the ai-start.md TODO; live
capture would clarify the enum.
No deck → ai_id=-1 fallback (the documented "no AI assigned" sentinel
per AIBattleStartTask.cs:21). 3 new wire-shape tests assert the
camelCase keys land verbatim in the JSON, plus self/oppo info come from
the right sources.

DoMatchingInternal calls IMatchingPairUpService.TryPairAsync, then maps:
- null result → 3002 RETRY (empty node_server_url, no battle_id)
- IsAiFallback → 3011 AI_BATTLE_MATCHING_SUCCEEDED
- IsOwner → 3007 SUCCEEDED_OWNER (cache pickup)
- joiner → 3004 SUCCEEDED
BuildForRankBattleAsync's InvalidOperationException (typically "no deck
for format") surfaces as 3001 ILLEGAL so the client shows the
matchmaking-error dialog rather than retrying.
card_master_id is a placeholder (0) per the per-battle card-master
split deferral. AI-fallback timing is covered by InProcessPairUp unit
tests; controller tests focus on the wire mapping (3002, 3004, 3007).
