feat(drlg): overhaul outdoor wilderness generator with strict D2MOO 1.13c parity (Fixes #455)
- Refactor entire wilderness generation pipeline under src/game/wilderness/ - Implement DRLGOUTPLACE dynamic level connection dimensions and orientation flags - Align outer river double-column generation (x = nGridWidth - 2) replacing perimeter trees - Implement authentic 4-pass secondary borders with 52 groups of DS1 substitution patterns - Align 56x8 TownSTrans gate to river boundary and place all 5 canonical presets - Replace dual road generators with single-pass orthogonal dirt path rasterizer - Initialize 0x40002 base floor grass and apply LvlSub.txt SubType 6 clustered replacements - Add D2MOO native mapgen parity fixtures and comprehensive stress & reachability test suites

# E2E Test Infrastructure — Diablo II: Lord of Destruction v1.13c Player Skill System (`diablo2-web`)
|
||||
# E2E Test Infra: Wilderness Map Generation Parity (Issue #455)
|
||||
|
||||
## 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`.
|
||||
## Test Philosophy
|
||||
- Opaque-box, requirement-driven. Derived from D2MOO v1.13c ground truth binary (`d2moo_mapgen`) and user requirements R1–R6.
|
||||
- Methodology: Category-Partition + Boundary Value Analysis + Benchmark Seed Workload Testing across outdoor levels (Level 2 Blood Moor, Level 3 Cold Plains, Level 4 Stony Field).
|
||||
|
||||
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 $\ge 100\%$).

## 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.
|
||||
## Pass/Fail Semantics
|
||||
1. Grid dimensions match D2MOO output exactly (width, height, room grid width/height).
|
||||
2. Outer river columns match exactly when river flags are present (`x = nGridWidth - 2` and `nGridWidth - 1`).
|
||||
3. TownSTrans is placed at `bx = 0` or `bx = nGridWidth - 7` with exact size 7×1 blocks (56×8 tiles).
|
||||
4. All required landmark presets (DenEnt, Pond1, Cott1, Circle, Clover) are present with valid coordinates.
|
||||
5. Secondary border tiles and 2×3 interior closures (`Bord9..Bord12`) are formed.
|
||||
6. Dirt path connects town exit to den and wilderness exit without spline deviations.
|
||||
7. TypeScript typecheck passes with 0 errors.

## Discovered Implementation Defects (Escalated to Milestones M1..M6)
|
||||
|
||||
Running `npx vitest run tests/wilderness-d2moo-parity.test.ts` discovered the following 6 implementation defects in `src/game/wilderness.ts`:
|
||||
1. **Defect 1 (Milestone M1)**: Blood Moor dimensions are statically hardcoded to 80×80 rather than dynamically calculated as 96×56 (horizontal) or 56×96 (vertical) via `DRLGOUTPLACE_CreateLevelConnections`.
|
||||
2. **Defect 2 (Milestone M2)**: River does not generate on outer boundary columns `x = nGridWidth - 2` (80) and `nGridWidth - 1` (88), and outer tree wall border pieces (`Bord*.ds1`) are not suppressed along the river column.
|
||||
3. **Defect 3 (Milestone M3)**: Missing 4-pass secondary border evolution (`BorderCliffs`, `BorderMiddle`, `BorderCorner`, `BorderBorder`) and interior 2×3 isolated forest closures (`Bord9..Bord12`).
|
||||
4. **Defect 4 (Milestone M4)**: River and Pond are mutually exclusive in `wilderness.ts`, preventing authentic concurrent placement of all 5 landmarks (`DenEnt`, `Pond1`, `Cott1`, `Circle`, `Clover`).
|
||||
5. **Defect 5 (Milestone M4)**: FarAway metric is missing, resulting in non-canonical placement of Den of Evil.
|
||||
6. **Defect 6 (Milestone M5)**: Dirt road generator uses Catmull-Rom splines instead of orthogonal Bresenham width-2 polyline vertex rasterization.
