Implements the item-state mirror + appraise round-trip infrastructure on top of Phase F.1's GameEvent dispatcher. Core layer (AcDream.Core/Items): - ItemRepository: ConcurrentDictionary-backed live item state keyed by server ObjectId. Events: ItemAdded, ItemMoved, ItemRemoved, ItemPropertiesUpdated. MoveItem handles container / slot / equip location updates atomically and fires ItemMoved with old+new container ids. UpdateProperties merges a PropertyBundle patch (for appraise results) without clobbering existing untouched keys. Wire layer (AcDream.Core.Net/Messages): - AppraiseRequest (0x00C8 C→S, inside 0xF7B1 GameAction envelope): Build(sequence, targetGuid) → 16-byte body ready for SendGameAction. - GameEvents.ParseIdentifyResponseHeader for 0x00C9 S→C — extracts (guid, appraiseFlags, success). Full PropertyBundle deserialization (the 10-flag bitfield-indexed tables) is a future pass; header alone is enough to route into the repository + surface "appraise complete" to UI. - GameEvents.ParseWieldObject (0x0023) — server-driven equip. - GameEvents.ParsePutObjInContainer (0x0022) — server-driven inventory move (item, container, placement). Tests (11 new): - ItemRepository: add/update fires correct event, move updates fields, missing-id returns false, remove, properties merge, clear. - Wire: AppraiseRequest byte-exact encoding, IdentifyResponse header round-trip, WieldObject round-trip, PutObjInContainer round-trip. Build green, 532 tests pass (up from 521). Phase F.2 unblocks the Paperdoll + Inventory UI panels and the "appraise on right-click" UX. Next pieces: PropertyBundle full deserializer (AppraiseInfo 10-flag bitfield), outbound move/drop/ pickup actions. Ref: r06 §1 (ItemType), §2 (EquipMask), §5 (appraise wire), §7 (pack depth rules). Ref: ACE GameEventIdentifyObjectResponse.cs for AppraiseInfo format. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
