d153bcb62c Enable equipment slot drag-and-drop via server swap packets
Replace the "not supported" error message with actual pickup from
equipment slots. Placing equipment items into backpack or bag slots
sends CMSG_SWAP_ITEM to the server.

a1457ee801 Fix NPC textures, bag item interactions, and Classic item query parsing
Rebuild creature display lookups after expansion-specific DBC layout loads
(was using WotLK defaults before turtle layout was available). Add full
drag-and-drop support for bag items with server-side CMSG_SWAP_ITEM packets.
Add Classic-specific SMSG_ITEM_QUERY_SINGLE_RESPONSE parser for Vanilla
format differences (fewer damage types, no scaling stats, no Flags2).

44d1431b60 Suppress login bind point message and auto-join Local channel
Only show "Your home has been set" when the player actively changes their
bind point (via innkeeper), not on the initial login sync from the server.
Add "Local" to the auto-join channel list for Turtle WoW compatibility,
with a settings checkbox and persistence.

381d896348 Implement bank, guild bank, and auction house systems
Add 27 new opcodes, packet builders/parsers, handler methods, inventory
extension with 28 bank slots + 7 bank bags, and UI windows for personal
bank, guild bank (6 tabs x 98 slots), and auction house (browse/sell/bid).
Fix Classic gossip parser to omit boxMoney/boxText fields not present in
Vanilla protocol, fix gossip icon labels with text-based NPC type detection,
and add Turtle WoW opcode mappings for bank and auction interactions.

0d4a9c38f7 Add guild features, fix channel joining, and improve whisper reply
Guild: add disband, leader transfer, public/officer note commands with
roster context menu showing rank names and officer notes column. Auto-refresh
roster after guild events.

Channels: fix city/region channels not working by accepting SMSG_CHANNEL_NOTIFY
during ENTERING_WORLD state (server auto-joins before VERIFY_WORLD) and handling
PLAYER_ALREADY_MEMBER notification.

Whisper: /r now switches to whisper tab and sets target to last sender,
matching WoW behavior.

Camera: extend WMO collision raycasting to work outside WMOs too.

1cfe186c62 Implement mailbox interaction and expansion-aware mail system
Fix mailbox right-click (transposed CMSG_GAMEOBJECT_USE opcode, missing
mail opcodes in Turtle WoW JSON, decorative GO type filtering). Add
expansion-aware mail packet handling via PacketParsers: Classic format
(single item, no msgSize prefix, Vanilla field order) vs WotLK format
(attachment arrays, enchant slots). Fix CMSG_MAIL_TAKE_ITEM and
CMSG_MAIL_DELETE for Vanilla (no trailing fields). Add pulsing "New
Mail" indicator below minimap, SMSG_RECEIVED_MAIL and
MSG_QUERY_NEXT_MAIL_TIME handlers, and async sender name backfill.

Remove PPM composite dumps, MODEL1_BOUNDS vertex analysis, TEX_REGION
logging, FOUNTAIN_PARTICLES debug output, and verbose chat/warden gate
logging. Add negative cache for failed texture loads to prevent repeated
file I/O for missing textures like deathknighteyeglow.blp.

ed6b305158 Fix character geoset mapping and texture corruption on equipment change
Corrected CharGeosets group assignments verified via vertex bounding boxes:
- Group 4 (401+) = gloves/forearms, Group 5 (501+) = boots/shins,
  Group 8 (801+) = sleeves (chest-controlled), Group 9 = kneepads,
  Group 13 (1301+) = pants/trousers, Group 20 (2002) = bare feet
- Changed bare shin default from 501 to 502 for better width match
  with thigh mesh (0.39 vs 0.32, thighs are 0.42)
- Added clearCompositeCache() to prevent stale composite textures
  from being reused across equipment changes
- Fixed character preview geoset defaults to match corrected mapping

SMSG_MAIL_LIST_RESULT, CMSG_SEND_MAIL, SMSG_SEND_MAIL_RESULT, mail take
money/item/delete/mark-as-read, and inbox/compose UI windows.

Fix periodic stuttering in Stormwind caused by synchronous per-line disk
flushes in the logger — remove fileStream.flush() and std::endl, downgrade
high-volume per-packet/per-model/per-texture LOG_INFO to LOG_DEBUG.

7f0eceaacc Fix PopStyleVar mismatches and character geoset IDs
Fix 9 PopStyleVar(2) calls that should be PopStyleVar(1) across
player frame, target frame, cast bar, party frames, buff bar, escape
menu, death dialog, and resurrect dialog. Fix action bar from
PopStyleVar(2) to PopStyleVar(4) to match 4 pushes.

Fix character geoset defaults: 301→302 (bare hands), 701→702 (ears),
1501→1502 (back/cloak), add 802 (wristbands). No WoW character model
uses geoset 301/701/1501; all use 302/702/1502 as base. This fixes
missing hands/arms on undead and other races with separate hand meshes.

- Load TaxiPathNode.dbc for MO_TRANSPORT world-coordinate paths (vanilla boats)
- Parse data[] from SMSG_GAMEOBJECT_QUERY_RESPONSE (taxiPathId for transports)
- Support vanilla M2 particle emitters (504-byte struct, different from WotLK 476)

f4f23eab7a Detect server disconnect during character loading and show error
GameHandler::update() now detects when the socket closes mid-session
(e.g. Warden rejection) and transitions to DISCONNECTED state.
Character screen shows a disconnect message instead of hanging on
"Loading characters..." forever. Reverted SHA1(seed+module) fallback
to SHA1(seed) since neither is correct without module execution.

f6a0be6a08 Fix empty chat messages and /dismount on Classic/Turtle
Chat: renderTextWithLinks now properly handles |cAARRGGBB color codes
that aren't item links (e.g. colored player names), rendering the text
in the specified color instead of discarding it.

Dismount: Classic/Vanilla lacks CMSG_CANCEL_MOUNT_AURA (TBC+ opcode).
Track mount aura spell ID when mountDisplayId changes, then use
CMSG_CANCEL_AURA as fallback on expansions without the dedicated opcode.

8282583b9a Fix equipment textures: correct DBC field indices and stop texture cycling
Binary ItemDisplayInfo.dbc has 23 fields with texture components at
14-21, not 15-22. The previous "fix" shifted all fields by +1 which
read wrong columns and broke both player and NPC equipment rendering.

Also fix local player texture cycling: rebuildOnlineInventory() was
called on every item query response (including for other players),
unconditionally setting onlineEquipDirty_ which triggered redundant
texture recompositing. Now tracks previous equipment displayInfoIds
and only sets dirty when they actually change.

Unified all 3 equipment texture code paths (local player, other
players, NPCs) to use the DBC layout system with correct field 14
base index.

tooltip with slot type, armor, and stats. Shift-click inserts the
item link into the chat input. Automatically queries server for

be425c94dc Fix SMSG_MESSAGECHAT parser missing receiverGuid for most chat types
The parser was not reading the uint64 receiverGuid that WoW 3.3.5
sends for SAY/GUILD/PARTY/YELL/WHISPER/RAID/etc types, causing all
incoming chat from other players to misparse (blank messages, wrong
type displayed). Also fix TEXT_EMOTE display to not prepend "You " for
incoming emotes from other players, and fix CHANNEL/ACHIEVEMENT types
to read the correct receiverGuid field.

emotes now send CMSG_TEXT_EMOTE to server and display incoming emotes
from other players. Channel system auto-joins General/Trade on login with
/join, /leave, and /1-/9 shortcuts. Chat bubbles render as ImGui overlays
above entities for SAY/YELL messages with fade-out animation.

886f4daf2e Add per-expansion asset overlay system and fix CharSections DBC layout
Expansion overlays allow each expansion to supplement the base asset data
via an assetManifest field in expansion.json, loaded at priority 50 (below
HD packs). The asset extractor gains --reference-manifest for delta-only
extraction. Also fixes CharSections field indices (VariationIndex=4,
ColorIndex=5, Texture1=6) across all DBC layout references.

85864ab05b Add separate draggable bag windows, fix dismount and player equipment
Bags are now individual draggable ImGui windows (backpack + each equipped
bag) with per-bag toggle from the bag bar. B key opens/closes all. A
settings toggle under Gameplay lets users switch back to the original
aggregate single-window mode. Window width adapts to bag item name length.

Fix dismount by clearing local mount state immediately (optimistic) instead
of waiting for server confirmation, and allow buff bar right-click dismount
regardless of the aura's buff flag.

Fix other players appearing naked by queuing them for auto-inspect when
the visible item field layout hasn't been detected yet.

22728b461f Fix vanilla M2 animations, movement packets, and DBC locale
- Parse vanilla M2 animation tracks (flat arrays with M2Range indices)
  instead of skipping them, fixing T-pose on all vanilla models
- Use C4Quaternion (float[4]) for vanilla bone rotations instead of
  CompressedQuat (int16[4]) which produced garbage transforms
- Fix vanilla M2 attachment struct size (48 bytes, not 40) so weapons
  attach to correct bones instead of model origin
- Route movement packets through expansion-specific packet parsers
  instead of hardcoded WotLK format, fixing server-side position sync
- Fix Spell.dbc field indices for classic/turtle (Name=120, Rank=129,
  IconID=117) - were pointing to Portuguese locale column (+7 offset)

- Route SMSG_UPDATE_OBJECT through polymorphic parsers for correct
  vanilla format (uint8 updateFlags, 6 speeds vs WotLK uint16/9)
- Fix SMSG_DESTROY_OBJECT for vanilla (8 bytes, no isDeath field)
- Add MSG_MOVE_* handlers for other player movement relay

- Resolve chat sender names from player name cache before display
- Fix CSV DBC field 0 always treated as numeric ID (fixes 16+ garbled
  Turtle CSVs including Map, AreaTable, Spell, CreatureDisplayInfo)
- Add CSV DBC validation: reject garbled CSVs (>80% zero IDs) and
  fall back to binary DBC files
- Fix ItemDisplayInfo texture component field index (14+ not 15+)
  for binary DBC with gender-aware suffix resolution
- Spawn other players as visible M2 models via creature callback
- Map name cache dedup prevents overwrites from duplicate CSV records

7092844b5e Add multi-expansion support with data-driven protocol layer
Replace hardcoded WotLK protocol constants with a data-driven architecture
supporting Classic 1.12.1, TBC 2.4.3, and WotLK 3.3.5a. Each expansion
has JSON profiles for opcodes, update fields, and DBC layouts, plus C++
polymorphic packet parsers for binary format differences (movement flags,
speed fields, transport data, spline format, char enum layout).

Key components:
- ExpansionRegistry: scans Data/expansions/*/expansion.json at startup
- OpcodeTable: logical enum <-> wire values loaded from JSON
- UpdateFieldTable: field indices loaded from JSON per expansion
- DBCLayout: schema-driven DBC field lookups replacing magic numbers
- PacketParsers: WotLK/TBC/Classic parsers with correct flag positions
- Multi-manifest AssetManager: layered manifests with priority ordering
- HDPackManager: overlay texture packs with expansion compatibility
- Auth screen expansion picker replacing hardcoded version dropdown
