The event queue's heap seq was the last GC'd block surviving across rounds: each round runs on a freshly spawned bot thread, so the N+1 thread realloc'd a block grown by dead thread N's allocator mid-round (at the next capacity doubling, ~turn 104) -> rawDealloc SIGSEGV in addEvent (7 gdb-confirmed coredumps). Replace with a static array[MAX_QUEUE_SIZE, BotEvent] + eventsLen: no heap block crosses threads, realloc can never happen. Also fix the harness aborting the final round mid-train: PPO_Bot's onRoundEnded trains synchronously after the runner's RoundEndedEvent, so the counter read right after awaitResults() is the stale pre-train value and System.exit killed the bot inside ppoUpdate. Poll up to 60s for the counter to catch up before declaring the battle incomplete. Verified: 72 consecutive rounds vs Fire, 100% wins, all rounds trained (counter advanced 1:1), zero coredumps since the fix.
