# E2E Test Infra: Wilderness Map Generation Parity (Issue #455)
# E2E Test Infrastructure: Diablo II 1.13c Item Drop Engine Parity (Issues #412–#428)
## 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).

The Diablo II Web Port Item Drop Engine test suite is built on a 4-tier opaque-box test architecture designed to enforce strict Blizzard v1.13c ground truth parity across all 17 inventoried features (Issues #412–#428).
## Test Architecture
- Test Runner: `npx vitest run tests/wilderness-d2moo-parity.test.ts`
- Ground Truth Binary: `/usr/local/google/home/taodao/tmp/d2moo_runner/d2moo_mapgen <levelId> <seed> <difficulty> <outJsonPath>`
- Golden Fixtures Directory: `tests/fixtures/d2moo/`
- `level2_seed_1.json` (Blood Moor Vertical 56×96, no river)
- `level2_seed_42.json` (Blood Moor Vertical 56×96)
- `level2_seed_12345.json` (Blood Moor Horizontal 96×56, river @ column 10/11)
- `level2_seed_0x12345678.json` (Blood Moor Horizontal 96×56, river @ column 10/11)
- `level3_seed_1.json` (Cold Plains 80×80)
- `level3_seed_0x12345678.json` (Cold Plains 80×80)
- `level4_seed_1.json` (Stony Field 80×80)
- `level4_seed_0x12345678.json` (Stony Field 80×80)

## 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.

## 2. Authoritative Ground Truth Oracles
Every test in this suite derives its expected values directly from authoritative Blizzard v1.13c artifacts:
1. **MPQ Data Tables (`/usr/local/google/home/taodao/d2-data`)**:
- `Patch_D2.mpq:data\global\excel\difficultylevels.txt`: Exact base upgrade divisors (`UberCodeOddsNormal`, `UberCodeOddsNightmare`, `UberCodeOddsHell`).
- `Patch_D2.mpq:data\global\excel\monstats.txt`: 734 monster kinds, `boss = 1` flag, and multi-difficulty `TreasureClass1..4`.
- `Patch_D2.mpq:data\global\excel\superuniques.txt`: 66 unique bosses and difficulty-specific TCs.
- `Patch_D2.mpq:data\global\excel\TreasureClassEx.txt`: Complete TC hierarchy, `picks`, negative picks (`picks < 0`), Countess item/rune tables, quest first-kill boss TCs.
- `Patch_D2.mpq:data\global\excel\ItemRatio.txt`: Quality ratios, divisors, and base chances for Magic, Rare, Set, Unique.
- `Patch_D2.mpq:data\global\excel\weapons.txt`, `armor.txt`, `misc.txt`: Base item `dropsound` and `dropsfxframe` definitions.
- `Patch_D2.mpq:data\global\excel\Levels.txt`: 138 level zones, area levels, and monster density configurations.
2. **D2MOO Decompiled C++ Assembly (`D2Game.dll`, `D2Common.dll`)**:
- `D2Game/src/ITEMS/Items.cpp:2142-2166`: Exact `/players N` NoDrop exponential dampening formula:
$$\text{eff} = p + \left\lfloor\frac{g - p}{2}\right\rfloor, \quad \text{ratio} = \left(\frac{\text{NoDrop}}{\text{NoDrop} + \text{TotalProb}}\right)^\text{eff}, \quad \text{NewNoDrop} = \left\lfloor \frac{\text{TotalProb} \times \text{ratio}}{1 - \text{ratio}} \right\rfloor$$
- `D2Game/src/ITEMS/Items.cpp:2346-2433`: Magic Find diminishing returns equations:
$$\text{Unique} = \left\lfloor\frac{250 \times \text{MF}}{\text{MF} + 250}\right\rfloor, \quad \text{Set} = \left\lfloor\frac{500 \times \text{MF}}{\text{MF} + 500}\right\rfloor, \quad \text{Rare} = \left\lfloor\frac{600 \times \text{MF}}{\text{MF} + 600}\right\rfloor, \quad \text{Magic} = \text{MF}$$
- `D2Common/src/Units/Units.cpp:3103`: Inventory gold limit:
$$\text{GoldLimit} = 10,000 \times \text{Level}$$

---
## 5. Coverage Thresholds & Quality Gates
1. **Pass Rate Gate**: 100% pass rate across all 198 tests. Zero tests skipped, zero flaky tests.
2. **Determinism Gate**: All drop rolling simulations MUST be seeded with deterministic `D2Rng` seeds to ensure repeatable runs.
3. **Anti-Silent Failure Invariant**: Missing data tables, invalid monster kinds, or unmapped TCs must raise explicit errors; fallbacks to synthetic constants or default TCs are strictly prohibited.
4. **Performance Gate**: The entire 4-tier suite (198 tests) must execute in under 15 seconds.

## Discovered Implementation Defects (Escalated to Milestones M1..M6)
## 3. How to Execute the Test Suite
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.

## 5. Ground Truth Invariants Tested
1. **Exact 1.13c Upgrade Divisors (`Difficultylevels.txt`)**:
- Normal: Uber Odds = 0, Ultra Odds = 0 (Base item upgrading unconditionally disabled).
- Nightmare: Uber Odds = 10 (Normal), 20 (Good); Ultra Odds = 0.
- Hell: Uber Odds = 20 (Normal), 40 (Good); Ultra Odds = 30 (Normal), 40 (Good).
2. **Zero Synthetic Loot Fallbacks**:
- Deletion of artificial item generators. Missing or invalid TCs cleanly return empty drop sets without fabricating items or falling back to `Act 1 H2H A`.
3. **Elite mlvl Bonus Mathematics (`MonsterUnique.cpp`)**:
- Champions: $\text{mlvl} = \text{base} + 2$.
- Uniques / Minions: $\text{mlvl} = \text{base} + 3$.
- Clamped strictly between 1 and 99.
- Demote to Normal logic cleanly reverses the $+2/+3$ bonus before inspecting base item level requirements.
4. **Diminishing Returns Magic Find (`Items.cpp:621`)**:
- $\text{EffectiveMF} = \lfloor \frac{\text{MF} \cdot \text{Factor}}{\text{MF} + \text{Factor}} \rfloor$
- Factors: Unique (250), Set (500), Rare (600). Magic (no diminishing returns).
5. **NoDrop Player Scaling (`D2Game!0x6FC3D280`)**:
- $N = \lfloor 1 + \frac{\text{GamePlayers} - 1}{2} + \frac{\text{PartyPlayers} - 1}{2} \rfloor$.
- $\text{ScaledNoDrop} = \lfloor \frac{\text{TotalProb} \cdot \text{Ratio}^N}{1 - \text{Ratio}^N} \rfloor$.
6. **Gold Inventory Capacity (`UNITS_GetInventoryGoldLimit`)**:
- $\text{MaxGold} = \text{Level} \times 10,000$. Overflows remain on ground with corresponding graphic tier (small: 1–49, medium: 50–499, large: 500+).
7. **Multi-Frame Death Animation Gating**:
- Item drops and audio SFX do not dispatch until the final frame of `mode = DT`. Cold shatter deaths dispatch items without corpse spawn.
8. **Quadrant Spiral Placement**:
- Isometric diamond scatter checks candidate coordinates by L1 Manhattan distance ascending, ensuring collision masks (`COLLIDE_WALL`, `COLLIDE_BLANK`, `COLLIDE_MASK_INVALID`) are never overlapped.
9. **Ground Item Label Text Colors**:
- Ethereal or socketed items of Normal/Superior quality strictly render in Gray (`#808080`), preserving Magic blue (`#6868ff`), Rare yellow (`#ffff64`), Set green (`#00fc00`), and Unique gold (`#c8a15a`).
10. **2-Pass Auto-Belt Routing**:
- Pass 1: Find existing column with matching potion type.
- Pass 2: Find first empty column.
11. **Multiplayer Lockstep Determinism**:
- Dual PRNG instances seeded with identical 32-bit values yield 100% byte-for-byte identical drop lists across Host and Client.
12. **Countess 6-Drop Cap & Paradoxical /players Scaling**:
- Countess raw table expansion ($5 \text{ items} + 3 \text{ runes} = 8$) capped to 6 items. Higher player counts reduce Countess Item NoDrop, leaving fewer slots for Countess Rune.
13. **Hellforge Smash Parity**:
- Exactly 1 rune (Hel–Gul on Hell, El–Amn on Normal) + 4 gems (1 perfect, 2 flawless, 1 normal).

## 6. Sign-Off & Next Steps
The E2E test harness is self-contained, reproducible, and fully verified.
The orchestrator may now proceed with milestone execution (M1 through M5) with guaranteed test feedback at every step.

/**
* Milestone 2 Empirical Stress & Statistical Verification Suite
*
* Requirements:
* 1. Player Scaling Statistical Monte Carlo:
* - Compare drop yields on regular monsters (Act 1 H2H A) under /players 1 vs 3 vs 5 vs 7 vs 8 (solo & partied).
* - Verify NoDrop rate dampening matches theoretical expectations within statistical variance (Z < 3.5, delta < 1%).
* 2. Multi-Seed PRNG Determinism:
* - Verify that setting /players N maintains identical PRNG stream determinism across 50 seeds in lockstep simulation.
* 3. Execution Robustness:
* - Run 50,000 drops across all difficulties with various player counts and equipment configurations.
* - Assert 0 exceptions, 0 NaNs, 100% valid bases, qualities, ilvls, and boss TC non-upgrades.
*
* Usage: npx tsx scripts/verify-challenger-m2-stress.ts

/**
* Milestone 3 Challenger Empirical Stress & Parity Verification Suite
*
* Exhaustive Empirical Verification:
* 1. Drop Placement Quadrant Scatter Parity:
* - 10,000 multi-item drops using findSafeDropPosition across 4 diverse map collision matrices:
* * Narrow Corridors (Tower / Arcane)
* * Chaos Sanctuary Star / Cross (lava borders & diagonal halls)
* * Catacombs (pillars, rooms, doors)
* * Maggot Lair (1-cell winding tunnels & dead ends)
* - Invariants: Zero wall penetration (COLLIDE_WALL), zero void penetration (COLLIDE_BLANK,
* COLLIDE_MASK_INVALID), valid floor grounding, anti-stacking burst dispersal, and quadrant symmetry.
* 2. Gold Pile Monte Carlo Distribution:
* - 100,000 gold drops across Normal, Nightmare, Hell difficulties.
* - Invariants: 100% conformance to 3-tier graphic cutoffs (flpgld_0: 1-49, flpgld_1: 50-499,
* flpgld_2: 500+), zero occurrences of artificial 5,000 clamp, presence of piles > 5,000.
* 3. Monster Seed PRNG Determinism with Queued Drops:
* - Verification of monster pendingDrop isolation from player movement, skill cast RNG,
* and runtime equipment/MF changes.
* - Out-of-order death animation completion and lockstep multi-session determinism.
*
* Usage: npx tsx scripts/verify-challenger-m3-stress.ts

/**
* Challenger M4-2 — Empirical Multiplayer Lockstep & Cross-Feature Stress Suite
*
* Covers:
* 1. Issue #427: Multiplayer Lockstep Determinism Under Stress
* - 60 seeds across 2, 4, and 8 peers, Normal/Nightmare/Hell difficulties,
* diverse monster ranks (normal, champion, unique, minion, boss, superunique),
* simultaneous multi-kills, and concurrent movement/attack/pickup inputs.
* - 100% bit-for-bit parity of computeLockstepHash, ground item coordinates
* (x, y, cellX, cellY), codes, qualities, sockets, ethereal flags, gold
* stack values, and uniqueId/dwInitSeed across all peers.
* - Single-field divergence sensitivity in computeLockstepHash for ground and
* inventory items (quality, stack, value, uniqueId, dwInitSeed, x, y).
* 2. Cross-Feature Integration (#423 + #424 + #425 + #427):
* - #423: 100% of lockstep-dropped items resolve valid flippy DC6 rects and render
* via drawGroundItem without procedural color-box fallbacks; fail-fast throw on
* missing sprite rect.
* - #424: Ethereal or socketed normal/superior non-runeword drops override ground
* label color to #808080 and sparkle aura to GROUND_ITEM_QUALITY_COLORS.low,
* while magic/rare/set/unique/runeword preserve authentic colors.
* - #425: 2-subtile (64px collision-box edge / 96px center) pickup boundary
* enforcement in both createNetSimulation and GameEngine + 2-pass belt routing.

* (5,808 non-empty combat combinations) + 66 SuperUniques × 3 difficulties = 198 combinations:
* 100% TC resolution in TreasureClassEx and 0 unhandled exceptions in executeDropPipeline.
* 2. All 136 Level IDs (Levels 1..136) × 3 difficulties:
* Town zero-density invariant (1, 40, 75, 103, 109), monster pack spawning,
* TC resolution for all pack members (normal, champion, unique, minion, boss, SuperUnique),
* executeDropPipeline execution, 100% walkable floor placement via findSafeDropPosition,
* and 100% flippy & inventory sprite resolution in BAKED_UI_MANIFEST.
* 3. 1,000,000-roll and high-sample statistical distributions:
* - Act 1 H2H A 1,000,000-roll NoDrop convergence to theoretical 62.5% (100/160) within ±0.25%
* - /players 1..8 NoDrop scaling formula and monotonic empirical drop yield
* - Baalq & all 5 Act Boss quest TCs (Andarielq, Durielq, Mephistoq, Diabloq, Baalq):
* 0% gold/junk, 0% normal/superior/low equipment, 100% rare/set/unique quality rolls
* - Countess (Normal, Nightmare, Hell): 6-item cap, rune tier ceilings, Hell pk1 rate (~7-12%)
* - Hellforge (Normal, Nightmare, Hell): 1/11 uniform rune distribution + 4 gems (1P + 2Fl + 1N)
