- Replace null with Option in GameResultStreamListener, PairingRepository,
ParticipantRepository, TournamentService
- Replace isInstanceOf checks with pattern matching in GameResultStreamListener
- Wrap var in SwissPairingService resolveConflicts with scalafix:off
- Apply spotlessScalaApply formatting across tournament and official-bots modules

- Add token field to OfficialBotAccount and generate a non-expiring bot
JWT on creation so official bots can authenticate
- Expose token in POST /api/account/official-bots response and open the
endpoint to any authenticated user
- Bridge TournamentService to Redis: publish gameStart events to
nowchess:bot:<name>:events after each pairing so OfficialBotService
picks up games automatically

Implements the full tournament lifecycle: create, join, withdraw, start,
round progression, and finish with Buchholz tiebreak standings.
- REST resource covering all 11 endpoints from the OpenAPI spec
- Swiss pairing algorithm with bye support
- Per-bot NDJSON stream with targeted gameStart events (color field)
- Game result ingestion via Redis writeback stream
- H2-backed integration tests for resource and pairing service

Replace synchronous account→core game-creation HTTP call and plain
pub/sub bot game-start events with Redis Streams using consumer groups,
XACK, retry, and a Dead Letter Queue for at-least-once delivery and
observability.
- account: GameCreationStreamClient publishes game-creation requests and
correlates responses via a per-instance consumer group (NCS-91)
- core: GameCreationStreamListener consumes requests, calls
GameCreationService, publishes response events, retries, and routes
exhausted/unparseable events to the DLQ (NCS-91, NCS-93, NCS-94)
- official-bots: bot game-start events migrated from pub/sub to Streams
with consumer group, XACK, retry, and DLQ (NCS-92)
- account EventPublisher dual-writes to the stream and legacy pub/sub
channel for backward compatibility
- all flows use the typed EventEnvelope (eventId/type/payload/timestamp/
correlationId) with DLQ error context (eventType, error, attempt)
- register new DTOs and EventEnvelope/EventType for native reflection
Closes NCS-91, NCS-92, NCS-93, NCS-94

Two bugs in move notation causing PGN import failures in LiChess:
1. Disambiguation: when two pieces of same type can reach same square,
SAN requires file/rank/full-square prefix (e.g. "Ndf3" not "Nf3").
Added disambiguate() in PgnExporter and disambiguatePiece() in
GameEngine, both querying allLegalMoves to find competing pieces.
2. Check/checkmate suffix: "+" and "#" were never appended.
PgnExporter now threads ctxAfter through moveToAlgebraic and
calls DefaultRules.isCheck/isCheckmate. GameEngine passes
PostMoveStatus to translateMoveToNotation for the same result.
Also removes dead notation code in executeMoveBody (result was never
used — not passed to MoveExecutedEvent).

When instance stream drops, immediately force delete the K8s pod (grace period 0). No waiting for health check or pod watch events.
Reduces failover latency and ensures stale pods don't linger.

Scale up: only if resource constrained (CPU/memory)
Scale down: only if NOT resource constrained AND game load low
Remove: triggering scale-up on unexpected instance failures
Keep: health monitoring (mark dead, delete pod, failover games) but no scaling
Prevents cascade scaling from transient health check failures.

Accidentally flipped pod matching direction in previous commits. Changed from correct instanceId.contains(podName) to incorrect podName.contains(instanceId), causing all health checks to fail.
Reverted all 3 locations to original working logic.
Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
Pod matching used endsWith(instanceId) which failed to match any pods because instanceId is randomly generated 8-char string, not pod name suffix. All instances marked dead causing cascading health check failures.
Changed to podName.contains(instanceId) to match instanceId embedded anywhere in pod name. Reverting incomplete fix from previous commit.
