 # Project: Diablo II: Lord of Destruction v1.13c Complete Player Skill System (`diablo2-web`)
 ## Architecture
 - **Ground Truth Stack**: Mounts `/usr/local/google/home/taodao/d2-data` (`d2data.mpq`, `d2char.mpq`, `d2exp.mpq`, `Patch_D2.mpq`) in overlay precedence order so `Patch_D2.mpq` provides authoritative 1.13c `.txt` tables (`Skills.txt`, `SkillDesc.txt`, `Missiles.txt`, `States.txt`, `ItemStatCost.txt`, `CharStats.txt`, `MonStats.txt`, `MonStats2.txt`, `Overlay.txt`, `PetType.txt`, `ElemTypes.txt`, `Events.txt`, `SkillCalc.txt`, `MissCalc.txt`) while `d2exp.mpq` provides `HitClass.txt` and `AnimData.d2` (`570,304` bytes, `3,558` records).
 - **Universal 1.13c Skill Engine (`src/game/engine/`)**:
  - `data-registry.ts`: Loads and indexes all 1.13c Excel tables and `AnimData.d2`.
  - `calc-ast.ts`: Complete `D2Common` RPN/AST formula evaluator supporting `lvl`, `blvl` (strictly base allocated `STAT_SKILLPTS` only — 1.13c Marrowwalk fix), `ulvl`, `par1..8`, `ln12..78`, `dm12..78`, `edmn`, `edns`, `edmx`, `edxs`, `enma`, `exma`, `usmc`, `toht`, `clc1..4`, `skill('...'.<prop>)`, `sklvl('...'.<lvl>.<prop>)`, `stat('...'.accr)`, `miss('...'.<prop>)`, and 1.13c table edge cases (unclosed `(` in Fire Wall, `par34` in Bone Wall, `*12`/`*16` in `royalstrikechainlightning`).
  - `stat-list.ts` & `state-bus.ts`: `D2StatListStrc` in 256-fixed-point (`<< HitShift`) integer arithmetic with `dwExpireFrame` expiration, curse exclusivity (`cursetype === 1` mutually exclusive, `STATE_ATTRACT` `cursetype === 2` immune to overwrite), aura stacking (`slvl` comparison + pulse lingering), and reactive `auraeventfunc` triggers (`Chilling/Frozen/Shiver Armor`, `Bone Armor`, `Cyclone Armor`, `Energy Shield`, `Iron Maiden`, `Life Tap`, `Clay/Blood Golem`).
  - `combat-pipeline.ts`: 1.13c `RollToHit` & `SUnitDmg` pipeline (`srcdam / 128`, AR vs Defense, Shield/Weapon Block, Amazon `Dodge`/`Avoid`/`Evade`, Masteries, Conviction/Lower Resist `1/5` immunity-breaking efficiency when base res >= 100%, `-Enemy Res`, Absorb, Blessed Hammer 1.13c rule NOT ignoring Undead/Demon Magic Resistance, Corpse Explosion `70%–120%` base monster HP, Venom `10`-frame poison duration clamp).
  - `anim-dispatcher.ts`, `missile-engine.ts`, `aura-scanner.ts`, `summon-manager.ts`: `AnimData.d2` frame event (`0x01` melee/cast, `0x02` missile) dispatcher with 1.13c `EIAS`/`EFCR` diminishing-returns speed scaling and `STATE_SKILLDELAY` cooldowns, `UNIT_MISSILE` loop (`pSrvDoFunc`, `pSrvHitFunc`, `pSrvDmgFunc`, `NextDelay`, Pierce, sub-missiles), radial Aura pulse scanner, and `SUMMON_CreatePet` manager enforcing `PetType.txt` caps/groups and 17 pet/trap AI sub-skills (`IDs 281..338`).
 - **7-Class Renderer & Verification Arena (`src/render/unit-sprites.ts`, `src/game/engine/world-arena.ts`, `acts.html`)**:
  - Decodes all 7 player classes (`am`, `so`, `ne`, `pa`, `ba`, `dz`, `ai` across `d2char.mpq` and `d2exp.mpq` with 16 composite layers `hd..s8` and frame `offsetX/offsetY` pivots), 391 `.dcc` missile sprites, 384 `.dcc` + 1 `.dc6` state/cast overlays, and 19 summon/trap/morph monster sprite tokens.
  - Exposes URL-driven deterministic arena mode (`acts.html?arena=1&class=<cls>&skill=<skillId>&slvl=<lvl>&autocast=1`) with targetable Normal, Undead, Demon, Immune, and Corpse units plus `window.__d2webArena` inspection and `triggerCast()` APIs.
 - **Zero-Conflict Isolated Worktree Skill Architecture (`src/game/skills/`)**:
  - `src/game/skills/registry.ts` auto-discovers per-skill modules in `src/game/skills/impl/<class>/skill-<id3>-<slug>.ts` via `import.meta.glob('./impl/**/*.ts', { eager: true })` (with fallback to `Skills.txt` data-driven `srvdofunc`/`srvmissile` execution).
  - Each isolated skill worktree (`../wt-skill-<id>` on branch `feat/skill-<id>`) adds only `src/game/skills/impl/<class>/skill-<id3>-<slug>.ts` and `tests/skills/<class>/skill-<id3>-<slug>.test.ts`, guaranteeing zero merge conflicts across all 221 skills.

 # E2E Test Infrastructure — Diablo II: Lord of Destruction v1.13c Player Skill System (`diablo2-web`)
 ## 1. Purpose & Opaque-Box Ground Truth Philosophy
 This document defines the requirement-driven, 4-tier End-to-End (E2E) test infrastructure for the Diablo II: Lord of Destruction v1.13c player skill system in `diablo2-web`.
 Every expected value in `tests/e2e-skills-113c/*.test.ts` is derived from the **authoritative 1.13c ground truth stack** in `/usr/local/google/home/taodao/d2-data`:
 1. **MPQ Archive Overlay Stack** (`src/mpq/mount.ts`):
   - `d2data.mpq` (`267,642,202` bytes) — Base classic tables & sprites.
   - `d2char.mpq` (`269,965,091` bytes) — Base 5-class (`AM`, `SO`, `NE`, `PA`, `BA`) composite character COF/DCC animations.
   - `d2exp.mpq` (`250,156,780` bytes) — Lord of Destruction expansion assets (`DZ` Druid, `AI` Assassin, `NE` expansion COFs), `data\global\excel\HitClass.txt`, and `data\global\AnimData.d2` (`570,304` bytes, `256` hash buckets, `3,558` 160-byte records).
   - `Patch_D2.mpq` (`3,912,204` bytes) — Highest-priority v1.13c patch override tables (`Skills.txt`, `SkillDesc.txt`, `Missiles.txt`, `States.txt`, `ItemStatCost.txt`, `CharStats.txt`, `MonStats.txt`, `MonStats2.txt`, `Overlay.txt`, `PetType.txt`, `ElemTypes.txt`, `Events.txt`, `SkillCalc.txt`, `MissCalc.txt`).
 2. **1.13c Binary Ground Truth Rules (`D2Common.dll`, `D2Game.dll`, `patch.txt`)**:
   - Whenever 1.10 (D2MOO) differs from 1.13c, the 1.13c MPQ data and 1.13c binary behavior take absolute precedence (e.g., Blessed Hammer `ID 112` does **not** ignore Magic Resistance of Undead/Demons; Corpse Explosion `ID 74` scales at `70%–120%` base monster HP; Venom `ID 278` clamps poison duration to `10` frames; `blvl` synergy evaluation strictly uses base allocated `STAT_SKILLPTS` only, preventing the 1.10 Marrowwalk charge bug; Conviction `ID 123` and Lower Resist `ID 91` operate at `1/5` efficiency when target resistance $\ge 100\%$).

 npx vitest run tests/e2e-skills-113c/
 ```
 ### Suite Files (`tests/e2e-skills-113c/`)

 ---
 ## 4. Contract Binding & Progressive Verification Architecture
 Each E2E test file binds to:
 1. **Live 1.13c MPQ Ground Truth (`/usr/local/google/home/taodao/d2-data`)**:
   - Directly mounts `d2data.mpq`, `d2char.mpq`, `d2exp.mpq`, and `Patch_D2.mpq` via `MountedArchives` (`src/mpq/mount.ts`) and parses the authoritative 1.13c tables (`Skills.txt`, `SkillDesc.txt`, `Missiles.txt`, `States.txt`, `ItemStatCost.txt`, `CharStats.txt`, `MonStats.txt`, `Overlay.txt`, `PetType.txt`, `ElemTypes.txt`, `HitClass.txt`, `Events.txt`, `SkillCalc.txt`, `MissCalc.txt`, and `AnimData.d2`).
 2. **Engine & Skill Module Contracts (`PROJECT.md § Interface Contracts`)**:
   - Dynamically loads `src/game/engine/*` (`data-registry.ts`, `calc-ast.ts`, `stat-list.ts`, `state-bus.ts`, `combat-pipeline.ts`, `anim-dispatcher.ts`, `missile-engine.ts`, `aura-scanner.ts`, `summon-manager.ts`, `world-arena.ts`), `src/game/skills/registry.ts`, and `src/data/gitea-skill-issues.json` when available, cross-checking their outputs against the 1.13c MPQ ground-truth oracle.

 /**
 * Diablo II v1.13c Authentic Dynamic Cursor & Idle State Machine (`src/ui/cursor.ts`).
 *
 * Implements:
 * - 3-State Cursor Machine:
 *   1. POINTING: Active state when mouse is moving or idle < 2000ms. Renders `protate` swaying frames.
 *   2. OPENING: Triggered after 2000ms of inactivity. Plays `ohand` 8 frames sequentially.
 *   3. OPEN_IDLE: Once `ohand` finishes, loops `orotate` 8 frames.
 *   - Any mouse movement or mouse event (mousedown/mouseup) resets the idle timer back to 0
 *     and returns immediately to POINTING.
 * - Accurate Hotspot and Coordinate Mapping:
 *   - Mouse position (mouseX, mouseY) is the cursor hotspot.
 *   - Hand cursor draws with index finger tip at (mouseX, mouseY).
 *   - Held items (this.inventory.cursorItem) are rendered centered at the cursor hotspot.
 * - Zero Runtime MPQ/DLL calls.

 /**
 * Unit & Parity Tests for Diablo II v1.13c Authentic Dynamic Cursor System (Issue #148).
 *
 * Verifies:
 * 1. Offline DC6 Cursor Extraction & Metadata Parity:
 *    - All 8 frames for protate.dc6, ohand.dc6, and orotate.dc6.
 *    - Zero runtime MPQ/DLL dependencies.
 * 2. 3-State Cursor State Machine Transitions:
 *    - Initial state is POINTING.
 *    - Inactivity >= 2000ms advances to OPENING (plays ohand 8 frames sequentially).
 *    - Completion of OPENING advances to OPEN_IDLE (loops orotate 8 frames).
 *    - Any mouse movement or mouse event (mousedown/mouseup) resets the timer and reverts to POINTING.
 * 3. Coordinates, Hotspot Alignment, and Rendering Bounds:
 *    - (mouseX, mouseY) tracking and bounds calculation.
 *    - Held items (cursorItem) rendered centered at cursor hotspot.
 * 4. Integration with HudManager & Canvas.
