- register_client now validates the client-supplied clientId (type, length,
charset) before it enters clientSocketMap as both key and value, closing a
map-poisoning / mapping-impersonation vector.
- mempoolNotified is now a Map with real TTL eviction owned by PaymentHandlers
(the actual dedup set). The dead duplicate Set in SocketHandlers and its
random-10%-per-cycle eviction (which could drop live entries) are removed;
addresses are also evicted promptly when monitoring stops.
- The SessionManager `sessions` cache is evicted on disconnect (removeSocket,
called after the suspend logic reads it) so it no longer grows unbounded
with every socket ever seen.
- sessionManager.dispose(), suspendedGameManager.cleanup() and
paymentHandlers.dispose() are wired into SocketHandlers.shutdown() so their
timers/maps don't leak on shutdown.
- checkGamesTimeout snapshots activeGames before iterating and awaits each
game-over sequentially (was mutating the Map during forEach and firing
async game-overs concurrently, which could skip games / double-process).
Adds inputValidation.test.js. Full suite: 19 suites / 149 tests.
