Conversation
…lization Add PersistentCombatStateStoreTest covering cache putIfAbsent semantics, clearCache, clearCacheWhenWritesSettle, awaitPendingWrites, applyCachedState (including invalid keys, unregistered keys, codec decode failures, and multiple state types), and warnUnregisteredStateKey dedup behavior. Expand BoostedExperienceRewardTypeTest, RedeemableExperienceRewardTypeTest, and RedeemableLevelsRewardTypeTest with coverage for all three deserializeAmount branches (missing key, Number subtypes, string parsing, non-numeric string fallback), localization-route and display label round-tripping, withExactAmount, withLocalizationRoute, withInlineDisplayLabel, describeForDisplay formatting, and isScalable.

Test the deferred-write branches.
This test only covers the branch where pendingWrites has no entry. It does not execute the completion callback that protects the cache while a write is pending.
Add controlled pending-write tests. Verify that the cache remains during the write, clears after a successful offline completion, and remains after a failed write or when the entity returns online.

Reject amounts outside the supported int range.
Number.intValue() and the direct cast in withExactAmount(long) narrow out-of-range values. For example, 2_147_483_648L becomes -2_147_483_648, so grant() skips the reward.
Validate before narrowing and throw IllegalArgumentException. Add boundary tests for deserialization and withExactAmount(long) in all three reward types.
