feat(drop): embed MonStats and SuperUniques with 1.13c multi-diff TC parity (Fixes #410, #411)

- Pack and embed authentic 1.13c MonStats drop columns (734 kinds) with noRatio support
- Embed SuperUniques multi-difficulty TCs (66 unique bosses) and fail-fast loading
- Fix SuperUnique minion TC3 inheritance and minion monsterType identification
- Add adversarial drop parity audit and superunique minion test suites
- Update D2MOO oracle seed generator and Paladin skill tree parity

/**
* Differential gate of the DRLG port: runs the native D2MOO oracle and the TypeScript port on the
* same game seeds and compares their schema-2 dumps stage by stage (drlg -> act -> per level
* levelGrid -> rooms -> maps -> warp -> activation). On a mismatch both sides are re-run with the RNG
* trace enabled and the first diverging seed operation is printed.
*
* Seeds are drawn at run time (crypto) unless given explicitly, so the gate cannot be satisfied by
* special-casing known seeds.
*
* Usage:
* npx tsx scripts/drlg-diff.ts [--levels 2-7,17,39] [--seeds 32 | --seed 0x12345678,0x5eed0100]
* [--difficulty 0] [--isolated] [--data tools/d2moo-oracle/data]
* [--stop-on-first] [--report out.json] [--no-activation] [--trace-check]
* Without --levels only the act stage (DRLG_AllocDrlg: layout, links, town) is compared.
* --no-activation compares every stage except room activation (the port does not activate rooms).
* --trace-check always traces both sides and also requires the complete RNG traces to be identical,
* which covers seed streams that are not dumped (e.g. the maze levels behind warps that room
* activation initialises through sub_6FD77BB0 -> DRLG_InitLevel).

*
* DS1 layers are parsed into Int32Arrays that are cached per file path, exactly like
* gpLevelFilesList_6FDEA700: the grids of every map/room using a file are views into the SAME
* arrays, so the in-place edits D2Common makes (DRLGPRESET_InitPresetRoomGrids ORs edge flags into
* the file layers) are shared the same way.
*
* D2_ALLOC_POOL memory is zero-filled, as in the native oracle (FOG_AllocPool -> calloc).

* Compiled 1.13c data tables consumed by the DRLG port, parsed from the game's `.bin` files with
* the exact record layouts of D2MOO (source/D2Common/include/DataTbls/*.h, commit 5596f5c,
* `#pragma pack(1)`, 32-bit pointers). These are the files D2Common itself loads, and the same
* files the native oracle (tools/d2moo-oracle) loads, so both sides consume identical data.
*
* A `.bin` file is an int32 record count followed by `count * sizeof(record)` bytes. Every loader
* checks the body size against the record size (a layout mismatch is a hard error).
*
* The D2MOO post-processing that matters for generation is reproduced:
* - LvlPrest/LvlSub/LvlTypes file names: '/' -> '\\', prefixed with DATA\GLOBAL\TILES\ when the
* name is longer than one character (DATATBLS_LoadLvlPrestTxt / LoadLvlSubTxt / LoadLevelTypesTxt).
* - LvlSub type start ids (DATATBLS_LoadLvlSubTxt).
* - MonPreset act sections (DATATBLS_LoadMonPresetTxt).

/**
* D2Common DRLG structures, ported from D2MOO (commit 5596f5c, MIT License, Copyright (c) 2020-2025
* The Phrozen Keep community): include/Drlg/D2DrlgDrlg.h, D2DrlgDrlgGrid.h, D2DrlgDrlgVer.h,

*
* Porting conventions (shared by every file of src/game/drlg/):
* - Field names are the D2MOO names so each function reads like its C++ original.
* - C unions are represented by ONE canonical field: rooms and levels only use `pDrlgCoord` /
* `pLevelCoords` (never nTileXPos/nPosX aliases); an orth keeps `pLevel` and `pDrlgRoom` as two
* fields and each call site uses the member the C++ code uses.
* - Pointers to embedded structs (e.g. `pOrth->pBox = &pLevel->pLevelCoords`) are object
* references, so writes through them are visible to the owner exactly like in C.
* - Grids are views: `pCellsFlags` is the backing Int32Array and `nCellsBase` the index of cell
* (0, 0); row offsets may use a stride different from nWidth (DRLGGRID_FillNewCellFlags).
* - Integer fields hold C int32 values; uint32 fields are normalised with `>>> 0` where the C++
* code relies on unsigned semantics or when they are dumped.

* Dedicated pure calculation, pulse cadence, and synergy formulas for the 10 Paladin Offensive Auras:
* - Skill 98: Might (ReqLevel 1)
* - Skill 102: Holy Fire (ReqLevel 6)
* - Skill 103: Thorns (ReqLevel 6)
* - Skill 108: Blessed Aim (ReqLevel 12)
* - Skill 113: Concentration (ReqLevel 18)
* - Skill 114: Holy Freeze (ReqLevel 18)
* - Skill 118: Holy Shock (ReqLevel 24)
* - Skill 119: Sanctuary (ReqLevel 24)
* - Skill 122: Fanaticism (ReqLevel 30)
* - Skill 123: Conviction (ReqLevel 30)
*
* 1.13c Ground Truth:
* - Skills.txt, Missiles.txt (Patch_D2.mpq)
* - D2Game/src/SKILLS/SkillPalAura.cpp
* - 50-frame pulse cadence (2.0s), 2-3s lingering duration
* - Fanaticism party physical %ED is strictly half of caster %ED
* - Conviction capped at -150% max resistance reduction, 1/5th efficiency vs element-immunes (base res >= 100%), no effect on Poison/Magic
* - Sanctuary radial pulse + knockback vs Undead, sets Undead physical resistance to 0%
* - Holy Freeze continuous slow (bypasses Cannot Be Frozen), radial cold pulse

/**
* Diablo II: Lord of Destruction v1.13c — Adversarial Challenger Verification Suite: Iteration 2
* Focus: Amazon Bow & Passive Skills Remediation Verification
*
* Empirical challenger verification probing:
* 1. Multiple Shot Center Arrow Count:
* - Exhaustive sweep across arrow counts 1..24 and up to 50:
* Confirm that when arrowCount >= 2, exactly 2 central arrows are flagged
* (indices Math.floor(count/2) - 1 and Math.floor(count/2)), for both odd and even counts.
* 2. Multiple Shot Proc & Leech Suppression:
* - Verify that outer arrows with canTriggerProcs === false have Life Tap,
* life leech, mana leech, knockback, and On-Striking procs strictly suppressed in combat execution.
* 3. Strafe Ammo Consumption:
* - Verify that casting Strafe (skill ID 26) decrements the quiver ammo by exactly 1 arrow per cast,
* and does not decrement per individual missile in the volley or drop below 0.
*
* Ground Truth:
* - Blizzard v1.13c: D2Common.dll, D2Game.dll, Skills.txt
* - D2MOO C++ reference: SkillAma.cpp (515-560, 253), MissMode.cpp (4748), SUnitDmg.cpp (1135)

*
* EMPIRICAL ADVERSARIAL STRESS SUITE:
* 1. Corpse Explosion:
* - 70%–120% monster base HP damage split into 50% physical + 50% fire.
* - Invariance: Damage does NOT scale with multiplayer health multiplier (must use single-player base monster life).
* - Radius: Scales at +0.33 yards/lvl (+1 subtile/lvl) starting from 2.66 yards at slvl 1.
* - Corpse consumption: Consumes corpse; cannot explode already consumed corpses.
* 2. Poison Nova:
* - Duration: Strictly 50 frames (2.0s) duration in 1.13c; does NOT increase with level.
* - Synergy: +10% poison damage per hard point in Poison Dagger and Poison Explosion.
* - Missiles: Spawns exactly 64 radial poison bolts in 360-degree ring.
* 3. Bone Armor:
* - Absorption: Absorbs physical damage only (elemental/poison bypasses).
* - Capacity: 20 base + 10/lvl, plus +15 absorb per hard point in Bone Wall / Bone Prison.
* - Collapse: When damage exceeds remaining absorb, absorbs remaining amount, drains pool to 0, and removes Bone Armor state.
* 4. Bone Wall & Bone Prison:
* - HP scaling: 19 base + (slvl-1)*4.6, multiplied by synergies.
* - Duration: Exactly 24.0s (600 frames).
* - Obstacle: Blocks unit movement and non-piercing missiles.
* 5. Teeth & Bone Spear & Bone Spirit:
* - Teeth: Multiple teeth fan, max 24 teeth; single target can only be damaged by 1 tooth per cast.
* - Bone Spear: Line projectile with collideKill=0 (pierces all targets in its path).
* - Bone Spirit: Homing missile tracking nearest target in 2:1 isometric ground perspective.

/**
* Adversarial Challenger Stress & Boundary Suite: Necromancer Summoning & Curses
* Cohort 3 Parity Stress-Testing (IDs 66..75, 86..95)
*
* Ground Truth Invariants Tested:
* 1. Skeleton Max Count: Exact formula across slvl 1..50 (slvl 1->1, 2->2, 3->3, 4->3, 6->4, 9->5, 12->6, 15->7, 18->8, 20->8, 30->12, 50->18).
* Skeleton Mastery: +8 life/lvl, +2 dmg/lvl, +10 def/lvl, +5% revive life/lvl, +10% damage/lvl.
* 2. Skeletal Mages: 4 elemental variants (Fire, Cold, Lightning, Poison) generate correct missile types, damage, and duration scaling.
* 3. Golems:
* - Clay Golem: slow-on-hit percentage formula min(75, floor(11 + 40*(slvl-1)/(slvl+6))), slow attacker when hit.
* - Blood Golem: 70% life steal to player, 30% damage transfer to master.
* - Iron Golem: inherits item properties and stats from targeted metallic item, innate Thorns reflection.
* - Fire Golem: Holy Fire radial aura and 100% fire absorb healing.
* - Golem exclusivity: Exactly 1 active golem allowed across all 4 types.
* 4. Revive: 180.0s (4500 frames) lifetime, +200% life (+5%/lvl SM), +215% damage (+10%/lvl SM), pet cap equals slvl.
* 5. Curse Exclusivity: Casting any cursetype=1 curse cleanly overwrites prior cursetype=1 curse without stat leakage across 100 cycles.
* 6. Attract Immunity: A monster affected by Attract (cursetype=2) CANNOT have Attract overwritten by any other curse.
* 7. Lower Resist Immunity Breaking: When base resistance >= 100%, Lower Resist applies at 1/5th efficiency.

/**
* Diablo II: Lord of Destruction v1.13c — Adversarial Challenger Verification Suite: Iteration 2
* Focus: Paladin Skills (IDs 96..125) Mechanics Remediation & Ground Truth Verification
*
* Adversarially probes:
* 1. Smite Equipment Leech Suppression:
* - Gear life leech (lifesteal, life_leech, item_parasite, life_leech_pct) is strictly 0.
* - Gear mana leech (manasteal, mana_leech, item_parasitemana, mana_leech_pct) is strictly 0.
* - Contrast: non-smite physical melee attacks correctly leech life and mana.
* 2. Life Tap Curse Healing Preservation:
* - Smite against a target cursed with Life Tap restores exactly 50% of dealt physical damage.
* - Smite with BOTH Life Tap on defender AND 50% gear leech on attacker heals strictly 50% (not 100%).
* - Smite against Physical Immune target with Life Tap heals strictly 0 HP.
* - Smite against 50% Physical Resistance target heals 50% of the mitigated damage.
* 3. Holy Shield Blocking Chance Parity:
* - dm56 formula parity across all levels 1..50: 10 + Math.floor((3300 * lvl) / (100 * (lvl + 6))).
* - slvl 1 evaluates to exactly 14% (not 13%).
* - slvl 20 evaluates to exactly 35% (not 36%).
* - Runtime state application toblock bonus matches across slvls.
* 4. SrvSt Pre-Cast Equipment Guards:
* - hasShield === false rejects Smite (#97) and Holy Shield (#117) with 0 mana spent.
* - weaponItemType === 'bow' or 'crossbow' or isRanged === true rejects Sacrifice (#96) and Zeal (#106).
* - undefined/omitted equipment properties retain permissive fallback for minimal fixtures.

* Challenger Adversarial Stress Test Suite — Paladin Defensive Auras & Aura Engine (Cohort 4).
*
* Covers 5 Core Mechanical Pillars:
* 1. Aura Pulse Interval & Lingering Cadence (50-frame strict cadence, 55-frame lingering, highest slvl precedence)
* 2. Holy Shield (Defense %, Duration, Smite flat dmg 5-band ladder, dm56 block chance & FBR analysis)
* 3. Redemption (50-tick cadence, 16 subtiles 2:1 iso radius, dm34 chance, life/mana restore, town suspension)
* 4. Cleansing & Meditation Prayer Synergies (free heal pulse, 0 mana drain, hard point blvl enforcement)
* 5. Vengeance Multi-Elemental Packet (independent Fire/Cold/Ltng damage, independent resistances, chill duration)

* Cohort 4 — Paladin Combat Skills & Offensive Auras (IDs 96..115)
* Adversarial Stress & Invariant Verification Suite
*
* Authored by: teamwork_preview_challenger (challenger_pal_1)
* Methodology: Pre-submission solution stress testing (Differential testing, Oracles, Adversarial Edge Cases)
*
* Probes the 5 Mission-Critical Mechanics:
* 1. Blessed Hammer 1.13c Magic Resistance Invariant (Undead/Demons do NOT bypass Magic Resistance; Magic Immunes take 0 damage)
* 2. Smite Mechanics (AutoHit vs extreme defense, base shield + Holy Shield flat damage, Leech suppression from items, stun duration formula)
* 3. Concentration Synergy to Blessed Hammer (Strictly 50% of listed %ED)
* 4. Conviction Invariants (-150% floor, 1/5th efficiency vs elemental immunes >= 100%, elemental only - zero effect on poison/magic)
* 5. Sacrifice Self-Damage (8% physical self-damage, caster HP clamped >= 1 HP)

# D2MOO DRLG oracle
Native build of [D2MOO](https://github.com/ThePhrozenKeep/D2MOO)'s `D2Common` level generator
(DRLG). It is the reference the TypeScript Act I outdoor port (`src/game/drlg/`) is diffed against,
stage by stage and RNG call by RNG call.
D2MOO's source is **not** vendored. The build reads it from `D2MOO_SRC` (default `~/tmp/D2MOO`),
pinned to commit `5596f5cb6c5251a0a07c6637d26458b06099d516` (MIT license). Only this driver, the
runtime shims and the build script live in this repository.
## Build and run
```sh
# 1. Game data: compiled tables, every DS1 of LvlPrest/LvlSub, every DT1 the DRLG loads.
npx tsx scripts/extract-d2moo-tables.ts samples/d2 tools/d2moo-oracle/data
# 2. 32-bit build (needs g++ with -m32 / gcc-multilib).
./tools/d2moo-oracle/build.sh
# 3. Generate.
./tools/d2moo-oracle/build/d2moo-oracle --data tools/d2moo-oracle/data \
--seed 0x12345678 --levels 2,3,4,5,6,7,17,39 \
[--difficulty 0] [--isolated] [--trace out.trace] --out out.json
```
- `--seed` is the D2 **game** seed (`DRLG_AllocDrlg` `nInitSeed`). The whole act, including the
level layout of `DRLGOUTPLACE_CreateLevelConnections`, derives from it.
- `--levels` must be Act I outdoor levels (DrlgType 3).
- `--isolated` allocates a fresh act for every level. The output must equal the sequential run,
which proves that a level's generation does not depend on other levels.
- Both `build/` and `data/` are git-ignored.
The binary is 32-bit so that every D2MOO struct has the exact layout of the compiled 1.13c `.bin`
tables. `LoadBinTable` checks `count * sizeof(record) == body` for every table.
## What runs natively
The driver runs D2MOO's own code for:
- `DRLG_AllocDrlg`: the seed chain, `DRLGOUTPLACE_CreateLevelConnections` and the town.
- `DRLG_InitLevel`, then `DRLGOUTDOORS_GenerateLevel` and `DRLGOUTWILD_InitAct1OutdoorLevel`.
- Room creation.
- Room activation, mirroring `DRLGACTIVATE_InitializeRoomEx` (DrlgActivate.cpp:317-331) and
`DRLGACTIVATE_RoomEx_EnsureHasRoom` (95-105) up to `DRLGROOMTILE_InitRoomGrids`:
1. `DRLGROOMTILE_LoadDT1FilesForRoom`
2. `DRLGPRESET_SpawnHardcodedPresetUnits` (preset rooms only)
3. `sub_6FD77BB0`
4. `DRLGROOMTILE_InitRoomGrids`, which re-seeds the room from `dwInitSeed`.
The outside world is provided by `src/stubs.cpp`. Its policy: anything the generator genuinely needs
is implemented with real data, and everything else **fails fast** (exit code 2).
**Real implementations:**
- Data tables: loaded in the same relative order as `DATATBLS_LoadAllTxts`. The monster tables
come first because the LvlSub DS1 loader translates monster preset units through MonPreset.
- DS1 archive reads.
- `DUNGEON_GameTileToSubtileCoords` and `DUNGEON_GameTileToClientCoords`.
- `sub_6FDAB750` and `sub_6FDAB610` (`src/path_misc.cpp`, copied from D2MOO PathMisc.cpp).
- **D2CMP tile libraries**, parsed from the real DT1 files. This is not optional:
`DRLGROOMTILE_GetTileCache` rolls the room seed iff the rarity sum of the matching tiles is > 0.
It runs inside LvlSub stamping (`sub_6FD8ACE0` → `DRLGROOMTILE_InitTileShadow`), so the tile data
advances the substitution RNG stream.
- For Act I every shadow lookup returns rarity 0, so there is no roll. This is visible in the
trace as `T 13 … 1 0`.
- The order of the returned tiles (slot order, then DT1 file order) is not verified against
D2CMP.dll. It only decides which tile variant is picked, and the oracle does not dump that.
**Modelling decisions (documented, not guessed):**
- Rooms are activated in `pFirstRoomEx` order. A preset map that spans several rooms loads its DS1
with the seed of the first activated room. That seed only matters for the randomly skipped units
of `DRLGPRESET_AddPresetUnitToDrlgMap` (Tormentor, Taintbreeder, Riftwraith, floor traps,
object 581), and none of those occur in Act I outdoor DS1s.
- Activating a room initialises the levels behind its warps (`sub_6FD77BB0` → `DRLG_InitLevel`).
The sequential mode therefore generates every requested level first and activates the rooms
afterwards, so each level's RNG trace stays under its own context.
- Tile selection (`DRLGROOMTILE_AddRoomMapTiles`) and unit spawning are outside the oracle.
## Output (schema 2)
```text
{schema: 2, oracle: {d2moo, arch: "i386"}, gameSeed, difficulty, isolated,
drlg: {startSeed, seed: [low, high]},
act: [{id, drlgType, levelType, coord: [x, y, w, h], flags, seed,
outdoor?: {flags, roomData: [orth]}, preset?: {direction, map}}], // sorted by id
levels: [{id,
levelGrid: {flags, coord, grids: [grid x4], ring: [vertex], nVertices,
vertices: [vertex x24], pathStarts: [null | [[x, y, dir, flags]...] x6],
roomData: [orth], seed}, // after InitAct1OutdoorLevel, before rooms
nRooms, rooms: [{type, coord, flags, otherFlags, dt1Mask, initSeed, seed,
outdoor?: {flags, flagsEx, subType, subTheme, subThemePicked},
preset?: {prest, picked, flags, map}}], // creation order
maps: [{prest, picked, coord, file, hasInfo, units}],
levelSeedAfterRooms, warp: {n, xy},
activation: [{seed, tile, wall, floor, dirt} | // outdoor rooms
{seed, walls: [grid], tiles: [grid], floors: [grid], shadow}, // preset rooms
... units]}]}
```
- `grid` is `{w, h, cells: [row-major int32]}`, or `null` when the grid was never allocated.
- `vertex` is `[x, y, direction, flags, next]`. `next` is -1 for null, 0..23 for `pVertices[i]`,
and 100+k for the k-th ring vertex.
- `orth` is `{level, dir, preset, init, box}`.
- Units are `[type, index, mode, x, y, spawned]`.
- All values are the raw packed words exactly as D2Common stores them.
## RNG trace (`--trace`)
The trace has one event per line. The TypeScript port writes the same format:
```text
I <label> <low> SEED_InitLowSeed (high seed 666)
S <label> <low> <high> SEED_SetSeeds
R <label> 0 <low>:<high> SEED_RollRandomNumber, 64-bit state after the roll (hex)
L <label> <max> <result> SEED_RollLimitedRandomNumber (max <= 0 does not roll)
P <label> 100 <result> SEED_RollPercentage
T <type> <style> <seq> <n> <sum> D2CMP_10088_GetTiles lookup: n tiles, rarity sum
# <context> driver context (drlg, L<id>, L<id>/a<room>)
```
Labels are `<context>#<n>`, assigned when a seed is initialised. The build fails if any D2MOO
object that rolls a seed was not compiled against the traced `include/D2Seed.h`.
## Defects of the previous ad-hoc runner (`~/tmp/d2moo_runner`)
Its output must not be used as a reference:
1. Outdoor rooms called `DRLGOUTPLACE_InitOutdoorRoomGrids` directly. That skipped
`DRLGROOMTILE_InitRoomGrids`' re-seed from `dwInitSeed` (D2Common.0x6FD89FA0), so every
substitution was rolled from the wrong seed.
2. `sub_6FDAB750` was stubbed to `return 0`. It drives the dirt-path search in `sub_6FD80750`, so
the dirt paths were corrupted.
3. Missing files returned a zeroed 64-byte buffer. MonPreset, Objects and SuperUniques were dummy
tables. `FOG_DisplayAssert` and `FOG_DisplayWarning` only printed.
4. It was a 64-bit build, which needed a hand-patched LvlSub layout.
5. D2CMP tile lookups were no-ops, so the shadow rarity rolls could not happen.

// the tile library functions are implemented here from the DT1 files. They are NOT optional:
// DRLGROOMTILE_GetTileCache (DrlgRoomTile.cpp:45-92) rolls the room seed iff the rarity sum of the
// tiles returned by D2CMP_10088_GetTiles is > 0, and it runs inside the LvlSub stamping of
// InitOutdoorRoomGrids (sub_6FD8ACE0 -> DRLGROOMTILE_InitTileShadow), so the tile data advances the
// substitution RNG stream. Only the per-query tile count and rarity sum influence the dumped grids.
// The ORDER of the returned entries (slot order, then DT1 file order) is not verified against
// D2CMP.dll; it only decides which tile variant GetTileCache picks, which the oracle does not dump.
