# Project: Diablo II: Lord of Destruction (v1.13c) Pure-Browser Online Client (`diablo2-web` `feat/netproto`)
# Project: diablo2-web Module Split & Single Entry Consolidation
## Architecture
- **Pluggable, Zero-Dependency Network & Protocol Layer (`src/netproto/`)**:
- Strictly isolated from DOM, Node.js, rendering, and game simulation (`tsconfig.netproto.json` sets `lib: ["ES2022"], types: []` for core `src/netproto/**`, excluding only `transport/ws-stream.ts` and `transport/node-tcp-stream.ts`).
- **L0 Transport (`src/netproto/transport/`)**: `ByteStream` interface implemented by `MemoryStream` (testing/offline replay), `WsStream` (browser WebSocket), and `NodeTcpStream` (Node CLI bot), plus `EndpointResolver` (`wsBridgeResolver` mapping `6112 -> /d2net/bnet`, `6113 -> /d2net/realm`, `4000 -> /d2net/game`; `tcpResolver`; and `mixedResolver` using direct TCP `101.37.117.183:6112` for BNCS and WSS for MCP/D2GS so Node bots do not consume the 5-per-IP `127.0.0.1` WSS bridge quota).
- **L1–L3 Protocol Engines (`src/netproto/{core,crypto,bncs,mcp,d2gs}/`)**:
- `crypto/`: Battle.net broken SHA-1 (`xsha1`), doubleHash, 1.13c CheckRevision constants (`exeVersion=0x01000d00`, `exeHash=0x7686beca`, `exeInfo="Game.exe 03/09/10 04:10:51 61440"`), and 16-char D2DV/D2XP CD-Key decode & hash.
- `bncs/`: `0x01` greeting + `0xFF | id | u16 len` framing, OLS auth (`0x50`, `0x25`, `0x51`, `0x3D`, `0x3A`), chat (`0x0A..0x0F`), and realm handoff (`0x40`, `0x3E`).
- `mcp/`: `0x01` greeting + `u16 len | u8 id` framing (`D2MCPClient.dll`), `0x01` STARTUP, `0x19` CHARLIST2 (with 33-byte `charStatString` parser), `0x02` CHARCREATE, `0x0A` CHARDELETE, `0x18` CHARUPGRADE, `0x07` CHARLOGON, `0x03` CREATEGAME, `0x04` JOINGAME, `0x05` GAMELIST, `0x06` GAMEINFO, `0x12` MOTD.
- `d2gs/`: Generated 1.13c S→C packet size table (`D2Net.dll` `0x6fbfa900` 181 entries + 14 variable-length formulas at `0x6fbf6750` and C→S `0x6fbfabd8` 113 entries) and canonical Huffman bit-length table (`Fog.dll` `0x6ff7f210` + `Fog.10219`/`Fog.10224` MSB-first decompressor); initial uncompressed `[0xAF, 0x01]` greeting followed by 1/2-byte `totalFrameSize` compressed blocks (`compressedPayloadLen = totalFrameSize - headerSize`); fail-fast `ProtocolError` on unknown packet IDs or size mismatches; complete S→C (`0x00..0xB4`) and C→S (`0x01..0x70`) codecs, `0x9C`/`0x9D` LSB-first item bitstream decoder (`ItemDataTables` injection), and `D2gsSession` (`0x68` 37-byte GameLogon, `0x6B` EnterGame, 5s 13-byte `0x6D` Ping).
- **L4 Neutral Domain & Flow (`src/netproto/domain/`, `src/netproto/flow/`, `src/netproto/index.ts`)**:
- `src/netproto/index.ts` exports ONLY protocol-neutral domain types (`ServerEvent`, `ClientCommand`, `GameServerAdapter`, `D2OnlineFlow`, `EndpointResolver`, `TextCodec`, `PacketTap`, lobby models). External code (`src/client/**`, `src/ui/**`, `src/scene/**`, `src/render/**`, `src/frontend/**`) never imports `src/netproto/{bncs,mcp,d2gs,crypto}/**`.
- **Runtime Seed-Driven DRLG & Tile Atlas Pipeline (`scripts/pack-tiles.ts`, `src/game/drlg/`, `src/client/map/`)**:
- `scripts/pack-tiles.ts` packs all `LvlTypes.txt` DT1s across Acts 1–5 plus the 3 mandatory universal DT1s (`Blank.dt1`, `InvisWal.dt1` with `style=49 sequence=7` collision floor, `Warp.dt1`) and compact DRLG `.bin`/`.ds1`/DT1-header metadata into `public/act-packs/tiles/`.
- `map-worker.ts` & `map-service.ts` run `createDrlgActSession` on `(act, mapSeed, difficulty, areaId)` from `LoadAct` and `RoomReveal` to produce exact pinned tile references, 16-bit sub-tile collision grids (`COLLIDE_MASK_INVALID` on void cells), warps, waypoints, and preset units matching D2GS cell-for-cell.
- **Packet-Driven Browser Client, Dual Viewport, Toolbar, Lobby, Audio & Inspector (`play.html`, `src/client/`, `src/ui/`, `src/frontend/`)**:
- `ClientWorld` maintains the authoritative server mirror (`units`, `modes`, `directions`, `stats`, `states`, `skills`, `inventory/equipment/belt/stash/cube/cursor/trade/merc`).
- `ViewportProfile` supports `800×600` (1.13c native) and `1024×768` (HUD anchored at native pixel dimensions with `(barOffsetX=112, barOffsetY=168)`, accurate screen-to-world mouse picking).
- Top DOM `Toolbar` (`src/client/toolbar/`) & `ClientSettings` (`localStorage['d2web.settings.v1']`): connection status/RTT + 5-per-IP/TLS diagnostics, Server Host editor (rejecting bare IP over `https:`), live `中`/`EN` toggle, lighting level selector (`auto`/1.13c, `LIGHTING_PRESETS`, `fullbright`), automap reveal (`off`/`level`/`act`), viewport toggle (`800×600`/`1024×768`), and Packet Inspector toggle.
`diablo2-web` is refactored in-repo on `/usr/local/google/home/taodao/diablo2-web/.worktrees/module-split` into five strictly isolated, compiler-enforced TypeScript modules under `src/` plus developer/verification CLI scripts under `tools/` and a single Web HTML entry (`play.html`):

## Interface Contracts
### 1. `src/netproto/index.ts` ↔ `src/client/**` & `src/frontend/**`
- `src/netproto/index.ts` is the ONLY allowed entry point into `src/netproto/` from outside `src/netproto/` (except `src/netproto/transport/*` where needed by Node scripts).
- Exports:
- `ByteStream`, `CloseReason`, `EndpointKind`, `EndpointResolver`, `createWsBridgeResolver`, `createTcpResolver`, `createMixedResolver`, ` createMemoryStreamPair`
- `TextCodec`, `createBrowserTextCodec`, `PacketTap`, `PacketTapEntry`, `ProtocolError`, `ClosedError`, `TimeoutError`, `Clock`, `systemClock`
- `UnitType`, `UnitRef`, `Pt`, `Hand`, `ItemContainer`, `ItemData`, `ItemStat`, `ItemDataTables`, `UnitSnapshot`, `SkillLevel`, `CharSummary`, `GameSummary`, `RealmInfo`, `ChatEvent`
- `ServerEvent` (discriminated union: `GameLoading`, `GameFlags`, `LoadAct`, `LoadComplete`, `UnloadComplete`, `GameLogout`, `RoomReveal`, `RoomHide`, `UnitAssign`, `UnitRemove`, `UnitMove`, `UnitReassign`, `UnitMode`, `SkillCast`, `StatSet`, `LifeMana`, `Experience`, `StateSet`, `StateEnd`, `ItemEvent`, `SkillList`, `ActiveSkill`, `Npc`, `WaypointMenu`, `QuestState`, `Party`, `Trade`, `Chat`, `PlaySound`, `Merc`, `Portal`, `Pong`, `Warden`, `SaveChunk`, `Opaque`)
- `ClientCommand` (discriminated union: `Move`, `MoveToUnit`, `SkillAt`, `SkillOn`, `SelectSkill`, `Interact`, `TakeWarp`, `ItemPickup`, `ItemDrop`, `ItemToCursor`, `ItemPlace`, `ItemEquip`, `ItemUnequip`, `ItemSwap`, `BeltPut`, `BeltRemove`, `BeltUse`, `ItemUse`, `SocketItem`, `IdentifyItem`, `NpcInit`, `NpcCancel`, `NpcBuy`, `NpcSell`, `NpcRepair`, `NpcHeal`, `NpcGamble`, `NpcIdentifyAll`, `NpcResurrectMerc`, `HireMerc`, `AddStatPoint`, `AddSkillPoint`, `WaypointGo`, `TownPortal`, `ClickButton`, `Party`, `Hostile`, `Trade`, `Chat`, `OverheadChat`, `Resurrect`, `SwapWeapons`, `Ping`, `LeaveGame`)
- `GameServerAdapter` (`state`, `send`, `onEvent`, `onClose`, `leave`, `stats`)
- `OnlineConfig`, `D2OnlineFlow` (`connect`, `createAccount`, `login`, `enterChat`, `joinChannel`, `sendChat`, `onChatEvent`, `listRealms`, `realmLogon`, `listChars`, `createChar`, `deleteChar`, `upgradeChar`, `charLogon`, `listGames`, `getGameInfo`, `createGame`, `joinGame`, `close`)
### 1. `src/common/data/data-registry.ts` ↔ Callers (`src/server/`, `src/client/`, `src/baker/`)
- `ArchiveSource` interface in `src/common/data/data-registry.ts`:
- `readText(mpqRelativePath: string): Promise<string | null> | string | null`
- `readBytes(mpqRelativePath: string): Promise<Uint8Array | null> | Uint8Array | null`
- `D2DataRegistry` and `getSharedDataRegistry(source: ArchiveSource)` MUST require an explicit `ArchiveSource` (no default `/usr/local/google/home/taodao/d2-data` path, no `node:fs`, no `window`/`fetch`). Missing `source` throws an explicit `Error` immediately (fail-fast per `AGENTS.md` §3.1).
### 2. `src/client/world/client-world.ts` ↔ `src/client/{map,motion,view,ui-model}/**`
- `ClientWorld` consumes `ServerEvent` via `apply(ev: ServerEvent): void` and exposes read-only snapshots of:
- `act`, `mapSeed`, `difficulty`, `hardcore`, `expansion`, `ladder`, `areaId`, `loading`, `selfId`
- `self: SelfPlayerState` (`unitId`, `name`, `charClass`, `level`, `x`, `y`, `life`, `maxLife`, `mana`, `maxMana`, `stamina`, `maxStamina`, `gold`, `stashGold`, `experience`, `stats`, `skills`, `leftSkill`, `rightSkill`, `runMode`, `weaponSet`, `mercId`)
- `units: ReadonlyMap<string, ClientUnit>` (keyed by `${unitType}:${id}`)
- `containers: ClientItemContainers` (`inventory`, `equipment`, `belt`, `stash`, `cube`, `cursor`, `tradeSelf`, `tradePartner`, `merc`, `shop`, `ground`)
- `revealedRooms: ReadonlySet<string>` (`${areaId}:${tileX}:${tileY}`)
- `waypoints: ReadonlySet<number>`, `quests: ReadonlyUint16Array`, `party`, `trade`, `chatLog`, `soundQueue`
### 2. `src/common/pack-contract/` ↔ `src/baker/` & `src/client/`
- Exports `PackedDrlgBundleManifest`, `PackedTileCatalogIndex`, `PackedTilePlacement`, `PackedDt1TileEntry`, `PackedDt1LibraryEntry`, `PackIndex`, `PackIndexEntry`, `PackObject`, `PackObjectFrame`, `PackSceneJson`, `EntityMeta`, `ClipMeta`.
- Exports fail-fast validators `validateUniversalDt1Libraries(libraries)` (enforcing `Blank.dt1`, `InvisWal.dt1` with style=49 sequence=7, `Warp.dt1`) and `validatePackManifest(manifest)` (enforcing `missingFiles === 0` and `missingTiles === 0`).
### 3. `src/client/map/map-service.ts` ↔ `src/game/drlg/**` & `src/client/view/scene-source.ts`
- `MapService.loadAct(act: number, mapSeed: number, difficulty: number, initialAreaId: number): Promise<LevelView>`
- `MapService.revealRoom(areaId: number, roomTileX: number, roomTileY: number): Promise<LevelView>`
- `LevelView`: `{ act, mapSeed, difficulty, areaId, originX, originY, width, height, collision: Uint16Array, blocked: Uint8Array, floors, shadows, walls, roofs, warps, presetUnits, automap, rooms }`
### 3. `src/client/map/map-service.ts` ↔ `tools/` & Browser
- `MapService.fromLoader(loader: PackedTileBundleLoader): Promise<MapService>` and `MapService.fromPackedUrls(baseUrl: string): Promise<MapService>` live in `src/client/map/map-service.ts` with zero `node:fs` or `node:path` imports.
- Node filesystem loading (`createNodePackedTileLoader(dirPath)` / `loadMapServiceFromPackedDir(dirPath)`) lives in `tools/lib/node-map-loader.ts` (or `src/baker/io/`).
### 4. `src/client/settings/client-settings.ts` & `ViewportProfile` ↔ `Toolbar`, `WorldRenderer`, `HudManager`
- `ClientSettings` stored under `localStorage['d2web.settings.v1']` with strict schema validation.
- `ViewportProfile`: `{ id: '800x600' | '1024x768', width: 800 | 1024, height: 600 | 768, barOffsetX: 0 | 112, barOffsetY: 0 | 168, panelOffsetY: 0 | 84 }`.
- `LightingInputs` decouples `src/scene/frontend/lighting-presets.ts` from `GameEngine`.
- `SceneSource` decouples `src/scene/frontend/world-renderer.ts` from `GameEngine`.
### 4. `src/netproto/index.ts` ↔ `src/server/adapter/LocalLoopbackAdapter.ts` & `src/client/`
- `LocalLoopbackAdapter` in `src/server/adapter/LocalLoopbackAdapter.ts` implements `GameServerAdapter` from `src/netproto/index.ts`:
- `connect(): Promise<void>`
- `disconnect(): void`
- `readonly isConnected: boolean`
- `readonly tick: number`
- `send(cmd: ClientCommand): void`
- `onEvent(handler: (ev: ServerEvent) => void): () => void`
- `onRawPacket?(handler: (direction: 'S2C' | 'C2S', opcode: number, bytes: Uint8Array, decoded?: ServerEvent | ClientCommand) => void): () => void`
- `src/client/**` never imports `src/server/**`; `src/client/main.ts` consumes any `GameServerAdapter` via `OnlineSession`.
## Code Layout
- `src/netproto/`: Isolated, zero-dependency network & protocol package (`core/`, `transport/`, `crypto/`, `bncs/`, `mcp/`, `d2gs/`, `domain/`, `flow/`, `ts/`, `index.ts`).
- `src/client/`: Packet-driven online client (`world/`, `map/`, `motion/`, `input/`, `view/`, `ui-model/`, `settings/`, `toolbar/`, `automap/`, `audio/`, `assets/`, `inspector/`, `session/`, `main.ts`).
- `play.html`: Online client HTML entry point with top DOM Toolbar and dual-viewport WebGL2 + 2D HUD canvas stage.
- `scripts/extract-d2net-tables.ts`: Deterministic 1.13c `D2Net.dll` & `Fog.dll` table generator.
- `scripts/d2-bot.ts`: Headless Node CLI bot (`register`, `login`, `chars`, `create-char`, `games`, `create-game`, `join`, `idle`, `record`, `walk`, `audit-levels`).
- `scripts/netproto-replay.ts`: Offline `.d2cap` JSONL capture replay & strict coverage verifier.
- `scripts/pack-tiles.ts`: Seed-independent DT1 tile library & DRLG metadata packer.
- `scripts/d2s-unlock.ts`: Safe offline `d2webbot*` `.d2s` waypoint & act-progression unlocker with timestamped backup.
- `scripts/verify-play.ts`: Headless Chrome CDP E2E verifier for `play.html` across `800×600` & `1024×768` viewports and all Toolbar controls.
- `tests/netproto/`, `tests/client/`, `tests/e2e-netproto/`: Unit, boundary, golden replay, and 5-tier E2E test suites.
---
## Code Layout & Write Ownership
- **Canonical `src/` directories (post-M3)**: ONLY `src/common/`, `src/netproto/`, `src/server/`, `src/client/`, `src/baker/`. All legacy top-level `src/` directories (`src/game/`, `src/scene/`, `src/mpq/`, `src/formats/`, `src/data/`, `src/render/`, `src/ui/`, `src/frontend/`, `src/audio/`, `src/sim/`, `src/i18n/`, `src/net/`) must be completely removed by the end of M3.
- **Concurrent Write Ownership**:
- `M1`, `M2`, and `M3` execute sequentially on the codebase so `git mv` and import codemods never collide.
- The parallel **E2E Testing Orchestrator** owns EXCLUSIVELY `/usr/local/google/home/taodao/diablo2-web/.worktrees/module-split/TEST_INFRA.md`, `/usr/local/google/home/taodao/diablo2-web/.worktrees/module-split/TEST_READY.md`, and `/usr/local/google/home/taodao/diablo2-web/.worktrees/module-split/tests/e2e-module-split/**`. It MUST NOT edit any file outside those paths.

# E2E Test Infrastructure & Philosophy (`feat/netproto`)
# Test Infrastructure & Strategy — `diablo2-web` Module Split (`TEST_INFRA.md`)
## Test Philosophy
## 1. Test Philosophy
The `feat/netproto` E2E test suite validates the complete Diablo II: Lord of Destruction v1.13c online protocol stack (`src/netproto/`), client world/map/motion state engine (`src/client/`), and browser UI/asset integration (`src/ui/`, `src/i18n/`, `scripts/`) under strict deterministic, hermetic execution guarantees:
1. **1.13c Binary Ground-Truth Parity**: Every protocol frame, bitfield, hash algorithm, compression table, and DRLG collision mask is verified against the canonical 1.13c binary tables (`D2Common.dll`, `D2Client.dll`, `D2Net.dll`, `D2MCPClient.dll`, `Bnclient.dll`, `Fog.dll`, and MPQ data tables `ItemStatCost.txt`, `Armor.txt`, `Weapons.txt`, `Misc.txt`, `Levels.txt`, `LvlPrest.txt`, `LvlTypes.txt`, `LvlWarp.txt`, `MonStats.txt`, `Objects.txt`, `SuperUniques.txt`, `Sounds.txt`, `SoundEnviron.txt`).
2. **Zero Live Network Dependency in Automated Runs**: All Vitest suites (`tests/e2e-netproto/tier1..4.test.ts`) execute 100% hermetically in-process using `createMemoryStreamPair`, `FakeClock`, `InMemoryPacketTap`, and `.d2cap` JSONL wire captures without opening any TCP or WebSocket connections to `101.37.117.183` or `www.laiseek.xyz`.
3. **Fail-Fast Protocol & Asset Validation**: Malformed packet headers, unknown opcodes, payload length mismatches, bitstream overruns, invalid item qualities/stat IDs, and unwalkable spawn coordinates throw structured `ProtocolError` or explicit validation errors rather than silently succeeding or returning permissive fallbacks.
4. **Protocol-Neutral Architectural Boundary**: Client and UI modules (`src/client/**`, `src/ui/**`) consume only the public domain boundary (`src/netproto/index.ts`: `ServerEvent`, `ClientCommand`, `GameServerAdapter`, `D2OnlineFlow`) and never import wire-level protocol internals (`src/netproto/{bncs,mcp,d2gs,crypto}/**`).
- **Requirement-Driven & Opaque-Box Verification**: Every test case in `tests/e2e-module-split/` is derived directly from `ORIGINAL_REQUEST.md` (`R1`–`R4` and Acceptance Criteria), `PROJECT.md` (`F1`–`F10` and Interface Contracts 1–4), and `AGENTS.md` (Diablo II v1.13c Ground Truth Parity Rules).
- **1.13c Ground Truth & Anti-Silent Failure Enforcement**:
- Universal DT1 libraries (`data\global\tiles\Act1\Outdoors\Blank.dt1`, `data\global\tiles\Act1\Barracks\InvisWal.dt1` with `style=49 sequence=7` collision floor, `data\global\tiles\Act1\Barracks\Warp.dt1`) must be unconditionally loaded per `D2Common.dll` `DRLGROOM_LoadDt1Files` (`0x6fdb8400`).
- Sparse/void cells must be blocked (`blocked === 1`) and masked with `COLLIDE_MASK_INVALID` (`COLLIDE_BLANK | COLLIDE_WALL`), and `findIsoSpawn` must never spawn in void or default blindly to geometric center `(width/2, height/2)`.
- Tile variant selection (`pickVariant`) must use high-entropy SplitMix64 2D spatial coordinate hashing without 45-degree diagonal striping.
- All 66 `SuperUniques` must preserve exact 1.13c `Class` and minion identifiers (`scarab2`, `zombie5`, `fetishshaman4`, `nihlathakboss`, `minion1`..`minion11` -> token `'XX'`, etc.).
- Missing required parameters (e.g., `D2DataRegistry` / `getSharedDataRegistry` called without an `ArchiveSource`) must fail fast by throwing an explicit `Error`.
- **Dynamic Import & AST/Filesystem Inspection**: All module imports inside `tests/e2e-module-split/*.test.ts` use runtime dynamic `await import(...)`, `node:fs` inspection, and source/AST boundary scanning inside `it(...)` blocks so the test files remain 100% valid TypeScript at all times and execute against the post-split architecture (`src/common/`, `src/netproto/`, `src/server/`, `src/client/`, `src/baker/`, `tools/`, `play.html`).

- Load and validate `public/act-packs/tiles/{index.json, drlg-bundle.json, drlg-bundle.bin}` against `src/common/pack-contract/` validators (`validateUniversalDt1Libraries`, `validatePackManifest`), and initialize `MapService.fromLoader` with an injected loader to generate an Act 1 level view without `node:fs` in `src/client/`.
6. **Scenario 6 — End-to-End Repository Architectural & Module Boundary Audit**:
- Programmatically scan every `.ts` file in `src/**`, `tools/**`, root `*.html`, `vite.config.ts`, `package.json`, and `tsconfig*.json` to verify all R1–R4 architectural invariants with zero exceptions.

## 5. Escalations / Notes for Orchestrator
- **Zero Implementation Bugs in `src/**`**: All 20 features (`F1–F20`) implemented in `src/**` conform to their contracts in `PROJECT.md` and pass all 236 E2E tests.
- **Minor Pre-Existing Type Errors in Unit Tests Outside E2E Scope** (not modified due to strict file ownership):
1. `tests/client/client-world.test.ts:253`: `rawValue` property in `ItemStat` object literal (`ItemStat` uses `{ statId, param, value }`).
2. `tests/client/hud-session-play.test.ts:436`: mock `GameServerAdapter` literal specifies `close` instead of `disconnect`.
