ci: bump version with Build-85

fix: coordinator auto-scaling, cache eviction, rebalancing, and grpc timeouts
Critical fixes: - Enable auto-scaling (was disabled in config) - Add periodic cache eviction (5m interval) — CacheEvictionManager never ran - Add periodic rebalance check (30s) — proactive load balancing - Add 5s timeout to all gRPC calls (batchResubscribe, unsubscribe, evict) - Use Option instead of null checks (scalafix compliance) These gaps left the coordinator unable to: 1. Scale up when instances overloaded (scaling was disabled) 2. Clean up idle games from memory (no scheduled eviction) 3. Rebalance load proactively (only on scale-up) 4. Handle hung instances (no RPC timeouts, operations could hang forever) Combined with prior fixes for instance metadata parsing and heartbeat TTL, the coordinator now handles overload scenarios correctly.

-# NowChess Tournament API
-
-Swiss-system bot tournaments. Bots are paired by score each round; all bots play every round (no eliminations). Game moves flow through the existing board and bot endpoints — the tournament module only orchestrates pairings, standings, and lifecycle.
-
---
-
-## Base path
-
-```
-/api/tournament
-```
-
-Routing: `/api/tournament` → `nowchess-tournament-active:8086`
-
---
-
-## Authentication
-
-All endpoints require a valid JWT (`Authorization: Bearer <token>`).  
-Bot-facing streaming endpoints additionally require the token's subject to match the registered `botId`.
-

-

-
---
-
-#### List registered bots
-
-```
-GET /api/tournament/{tournamentId}/bots

-
-#### Get standings

-```
-GET /api/tournament/{tournamentId}/standings
-```
-
-Response `200 OK`:
-
-```json
-{ "standings": [ /* Standing[] */ ] }
-```
-
---
-
-#### Get pairings for a round

-
-### Bot streaming
-
-#### Stream tournament events
-
-```
-GET /api/tournament/{tournamentId}/stream
-```
-
-Headers: `Accept: text/event-stream`
-
-Server-Sent Events stream scoped to this tournament. The bot receives `pairingReady` events when it is assigned a game, at which point it should connect to the existing bot game stream:
-
-```
-GET /bot/stream/game/{gameId}    (existing endpoint)
-POST /bot/game/{gameId}/move/{uci}  (existing endpoint)
-```
-
-The tournament module never sends moves — bots do that themselves through the existing bot endpoints.
-
---
-
-## Typical bot flow
-
-```
-1. POST /api/tournament                          # director creates tournament
-2. POST /api/tournament/{id}/bots               # each bot registers
-3. POST /api/tournament/{id}/start              # director starts
-4. GET  /api/tournament/{id}/stream  (SSE)      # each bot opens stream
-
-   -- per round --
-5. receive: pairingReady { gameId, color }
-6. GET  /bot/stream/game/{gameId}               # existing endpoint
-7. POST /bot/game/{gameId}/move/{uci}           # existing endpoint, repeated
-   -- game ends --
-
-8. receive: roundFinished
-9. GET  /api/tournament/{id}/standings          # optional, inspect scores
-   -- repeat 5–9 for each round --
-
-10. receive: tournamentFinished
-11. GET /api/tournament/{id}/standings          # final ranking

TeamCity	56f0030a83	ci: bump version with Build-85	2026-05-13 20:48:35 +00:00
Janis	d0c71693bb	fix: coordinator auto-scaling, cache eviction, rebalancing, and grpc timeouts Build & Test (NowChessSystems) TeamCity build finished Details Critical fixes: - Enable auto-scaling (was disabled in config) - Add periodic cache eviction (5m interval) — CacheEvictionManager never ran - Add periodic rebalance check (30s) — proactive load balancing - Add 5s timeout to all gRPC calls (batchResubscribe, unsubscribe, evict) - Use Option instead of null checks (scalafix compliance) These gaps left the coordinator unable to: 1. Scale up when instances overloaded (scaling was disabled) 2. Clean up idle games from memory (no scheduled eviction) 3. Rebalance load proactively (only on scale-up) 4. Handle hung instances (no RPC timeouts, operations could hang forever) Combined with prior fixes for instance metadata parsing and heartbeat TTL, the coordinator now handles overload scenarios correctly.

Janis	380a2cceeb	feat: add periodic health check to evict dead instances Build & Test (NowChessSystems) TeamCity build failed Details Add quarkus-scheduler dependency and schedule health check every 10 seconds.

Janis	43184d296d	fix: remove corrupted instances immediately and evict dead instances Problem: Dead instances pile up indefinitely. Failed metadata parsing leaves stale data in registry. No cleanup mechanism exists. Changes: 1. Remove instance from registry on parse failure (corrupted metadata = unrecoverable) 2. Evict instances with state="DEAD" on next health check (was only evicting by heartbeat age) This prevents: - Memory leak from accumulating dead/corrupted instances - Stale data persisting after parse failures - Dead instances blocking resources indefinitely Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>	2026-05-13 18:25:12 +02:00
