Quality pass from the 2026-06-04 BattleNode review (audit in the outer
repo). All changes are behavior-preserving — identical wire bytes,
verified by the full 1008-test suite staying green.
- Name scattered magic numbers: crypto key/IV lengths, outbound-sequencer
base, WS receive buffer / EIO ping / SID length, polite-close timeout,
upgrade-credential keys, battle-id digit math, deterministic-turn spin.
- resultCode = 1 -> (int)ReceiveNodeResultCode.Success across body records.
- Pong "3" -> EngineIoPacketType.Pong; remove dead NoOpBotParticipant.Touch
(replace with #pragma warning disable CS0067).
- Wire-flag enums, serialized as numbers via JsonNumberEnumConverter:
turnState -> TurnState{First,Second}, isSelf -> CardOwner{Opponent,Self},
open -> ChoiceVisibility{Hidden,Open}.
- isOfficial / isInvoke -> bool / bool? via new NumericBoolJsonConverter
(reads/writes 0/1; TDD'd). Scoped to the BattleNode wire boundary only;
MatchContext and the HTTP/AI-start path stay int (AI-start uses -1 as a
sentinel, so it is not boolean).

Audit Md11 (part 2 of 2). Adds an explicit Clear() so BattleSession can
release the archive at battle-end instead of waiting for the participant to
be GC'd. _next is intentionally NOT reset — a post-Clear emit is a bug per
the design, but the seq stream must stay monotonic if it does happen.
Tests cover empty archive after Clear, _next preservation across Clear,
and Clear-on-empty no-op. The BattleSession integration that calls Clear
lands in the next commit.
