# RuneWaker Native Disarm Main-Hand Audit (2026-10-05)

## Finding and scope

The local RuneWaker RoleAttr source initializes a missing main hand as `EM_Weapon_Unarmed` with speed 30, and its unarmed Main_DMG path supplies `Level * 2` when the main-hand base damage is zero. This is enough to replace the training weapon inputs for native Main_DMG-dependent formulas. It does not justify a WoW punch constant or a blanket multiplier. The implementation is opt-in through the native amount adapters; the separate WoW compatibility formula is not changed here.

The verified profile applies to the five active native player-build identities and their generated party-NPC derived-stat snapshots: Knight/Scout, Priest/Knight, Rogue/Warrior, Scout/Rogue, and Mage/Warlock. It retains the existing training-profile `residualFlatDamage` bridge and tracked generic physical-damage multiplier. The native stat model does not represent all weapon-category damage/speed rates, so the profile records a neutral-rate boundary rather than claiming exactness for those channels.

## Primary local source evidence

| `SourceCodeVS2019/Server/NetGameServer/MainProc/Global_SimpleSchedular.cpp` | `5DCDBDD69EEFE1086E2087AB167270D580884929A083E4E69032C773F7F941AC` | Main-hand auto scheduling adds `int(Fin.Main_ATKSpeed)` to the server clock (line 445), so this source speed unit is milliseconds. The source auto-hit then calls `MainAtkDamage` (line 633). |
| `SourceCodeVS2019/Server/NetGameServer/MainProc/MagicProc/MagicProcess.cpp` | `B2EEE402FDF9AC488ABE62DC8D2EC9C52B312542EF06D95A6B6FF594711CA7C3` | Physics damage uses `Main_DMG * 10 * SpellTime / Main_ATKSpeed` (line 2327). Physics_Point subtracts `Main_DMG * Dmg_MagArg` once for fixed effects or times SpellTime otherwise (lines 2384–2386). These are native ability branches that must see the unarmed main-hand inputs after Disarm. |

Their source metadata pins `magiccollectobject.db` (`4aae19865cb07b30f99945aa7319a0096db244ff5e5b4b5d902fc6889474f501`) and `magicobject.db` (`52af13a2d8cfa9a66d4caa2d3c38832edc232f058995a64ef8135a6b82e43691`) for player attack/periodic rows. The native stat-rule artifact pins `racetable.db`, `sextable.db`, `voctable.db`, and `fixtable.db`; `romNativeStatRules.generated.json` SHA-256 is `6DA531D6D56642013155438B93BB55C120A6421C7C12858CAD8C1B934E1E4E99`.

The training item curve used for the bridge is `src/game/generated/romNativeDamageTrainingProfiles.generated.json` (SHA-256 `A3E064F536F4E1EFAFA076D13755DE5DC62C23B20A496AE572F783126DBE3BCB`). It records `romHeirloomReference.json` SHA-256 `4E5194A28C2764838C5862C1F3DB505F5BE3CE99143A4440BAECF5E38C3099BF` and the source item-database hashes: `armorobject.db` `A2F0017C4772165D562EBB08CA0AC51625CDC4453E3670A1501DF7D741D2BAD3`, `weaponobject.db` `2BC28EEBBE413BD6118F027E3FEC1A3953CEF371476937D0B65622C542971A67`, `addpowerobject.db` `D651861FC5918BAC937D726D754D17A92DA34DB5059F9C70AC9F6B2C15711432`, and `string_enus.db` `4FCE021BA9ED110A213E08D3228B2DE57CEC66DDBBC8DCF5753204874D9AB75`. These are the pins recorded by the generated reference, not a claim that the separate active `Runewaker/Resource/data` directory has those same hashes.

## Implemented formula and adapter contract

For a verified active-five native training profile, the source-shaped unarmed main-hand amount is:

```text
Main_DMG_unarmed = max(1, (residualFlatDamage + Level * 2) * physicalDamageRateFactor)
Main_ATKSpeed_unarmed = 30
Main_attack_interval = 30 * 100 ms = 3000 ms
```

`residualFlatDamage` is the existing native training-weapon bridge remainder after the generated profile's weapon contribution is removed. The `physicalDamageRateFactor` remains applied. Main-hand-only rate channels that this stats bridge cannot supply are held neutral and explicitly surfaced as `unmodeledRateChannels`: `Main_DMG_Per`, `DMG_AllWeapon`, `DMG_Unarmed`, `AtkSpeed`, `Main_ATKSpeed_Per`, `AttackSpeed_AllWeapon`, and `AttackSpeed_Unarmed`.

`nativeDisarmedMainHandAutoAttackProfile(caster)` only returns a profile when the current native derived stats match the canonical active-five training-gear profile. It identifies the main source as `runewaker-roleattr-unarmed-main-hand`, has no training weapon item IDs, and leaves `physicalAttack` intact. This profile is the prepared optional override for:

- `nativeDamageCasterAmount(..., targetContext?, mainHandOverride?)`: when the bound native component is calculation type 0 or 9, or has a nonzero fixed contribution of type 2, the adapter validates the override and feeds the lower native resolver a copied training profile whose main hand is `Level * 2`, speed 30, and `sourceItemIds: []`. The residual, generic rates, off-hand, and ranged entries are retained. Other components do not consume the substituted main-hand fields; a ranged branch therefore keeps its existing ranged inputs.
- `nativePeriodicDamageCasterSnapshot(..., magicResistance?, effectiveMagicPower?, mainHandOverride?)`: only the physical negative HP DotMagic rank-correction branch consumes the override. Other periodic branches keep their current source behavior.

In both APIs an omitted override preserves the pre-existing native calculation. A stale or invalid supplied override fails closed for a branch that consumes Main_DMG/Main_ATKSpeed (`null` for direct damage, `undefined` for a periodic snapshot). Custom/unverified gear returns no disarmed profile; callers must keep their existing explicit fallback behavior. This does not grant spell usability or certify native weapon/category prerequisites for every ability.

## Known limits

- This is the source main-hand input before `MainAtkDamage` variance, hit, target defense, crit, and other downstream combat resolution. It is not a complete auto-hit result.
- The native rules sidecar models generic physical damage rate, not all seven unarmed/main/all-weapon rate channels listed above. Their neutral values are a boundary of this implementation, not a source claim that the rates are always 1.
- The profile is verified against canonical generated training gear's tracked aggregate stats. A custom set whose tracked totals differ fails the gate, but a custom set with identical aggregates cannot be distinguished because the native gear payload has no item provenance. Equipment-specific `BaseEQ.Main_DMG` effects and unidentified weapon/category rate modifiers remain unmodeled.
- Existing ability cast/equipment prerequisites remain unchanged and unverified by this amount adapter. Direct abilities continue through their existing shared status/availability checks.
- The active-five generated party-NPC profile test establishes the stats preparation and formula input shape; it does not certify all classes, every NPC type, every ability, or native combat readiness.

## Verification

Focused source tests passed:

```text
npx vitest run src/game/romNativeDisarm.test.ts src/game/romNativeCombatAmount.integration.test.ts src/game/romNativePeriodicDamage.test.ts src/game/romNativeDamage.test.ts
4 files passed; 25 tests passed.
```

The Disarm tests cover all five active identities as player and configured party-NPC derived stats, preserve the residual and tracked multiplier, reject custom gear and stale override values, confirm native main-hand-consuming basic-attack branches change while the ranged Scout Shot remains unchanged, and verify a physical DotMagic rank correction responds to the unarmed inputs. This was a scoped source/runtime test run, not a full balance/readiness pass.
