Sets are Unique and Apex item pieces (Set ID + piece index), not chips. Artifact sockets on Unique / Apex only (one per item). Legendary never carries a Set ID and has no Artifact socket.

• Receiver: Aim Assist baselines (Magnetism / Stickiness / Rotation / Strafing) + Fire Mode + cadence unit; also the art subclass body on the Class Frame.
• Frame archetype: cadence number, recoil pattern, Impact / Mag / Range band bias (data only — same Class Frame look).
• Class: Frame chassis look (one mesh per Class).
• Parts: never rewrite AA or cadence.
• Sniper Optics: long-range Optics do not rewrite AA (ADS / zoom / initial accuracy only).
• Band enum (Year-1): Low · Mid · Mid-High · High · Very High.
• Float maps: TBD-AA-FLOAT / TBD-IMR-FLOAT.

• Class = Spine: one core chassis per Class; everything attaches to the Spine.
• Frame archetype = data only: Adaptive, Aggressive, Precision, Rapid-Fire, Lightweight, High-Impact, specialties (cadence · Impact / Mag / Range · gunfeel). Does not change Spine art.
• Receiver = subclass body: one mesh per Type; seats onto Class Spine before Barrel.
• Tip-share Classes: Receiver owns length + universal Barrel tip socket.
• Gatling: three Class-scaled Receiver bodies (Rifle / Machine Gun / Heavy Gun).
• Shared kinetic Barrels: one Soft Object Path 5-pack for Rifle Auto/Pulse/Scout/SMG + Hand Cannon + Sidearm + MG (fully shrouded).
• Player / Refit word: Barrel.
• Hand Cannon + Sidearm: Underlug (visible under-barrel block) instead of Brace; no Front Grip.
• Bow: Limbs · Quiver/String · Sight · Grip · Stabilizer (not Front Grip).
• Own Barrel meshes: Shotgun / Sniper / Gatling×3 / Heavy / GL.
• Rocket: Tube + Backblast Collar (rear exhaust — not Warhead).
• Modules: Mag / Stock|Brace / Optic / Grip / Front Grip (long-gun only) / Underlug (pistols) / Bow Stabilizer — unless keyed (Sniper Optic; Coil / Rail / Emitter; Tube / Backblast Collar; Limbs / Prod; Cylinder; GL Year-1 Breech — drums later).
• Specialty Frames: share the Class Spine. Sniper reuses Rifle Spine.
• Assembly: Class Spine → Receiver → modules.

Artifact Socket Contract

• Artifact sockets exist only on Unique and Apex items. Legendary never.
• Common, Uncommon, Augmented, and Rare items cannot socket Artifacts.
• Eligible slots when the item is Legendary/Unique or Apex: Weapon 1–4, Wrist Melee (Razors/Blades), Physical Shield, Helm, Chest, Gloves, Belt, Boots, Energy Shield, Ring 1, Ring 2, Amulet. Wrist Melee = equipable melee slot (hotkey 1). Energy Shield slot = Barrier / Aegis gear only. Physical Shields use the dedicated Phys Shield paper-doll slot.
• One Artifact per item only — cannot dual-stack Artifacts on a single piece.
• Artifact socket is separate from gem / jewel / Phonon Shard sockets.
• Unique and Apex pieces with a Set ID count toward that Set’s equipped total (only while the SetID is in ActiveSetIDs under ASBP=6). Legendary never counts and has no Artifact socket.
• Socketing/unsocketing Artifacts uses Crafting Page rules (material cost TBD).

How Sets Work

• Each Unique / Apex Set piece belongs to a Set ID (e.g. a named Apex-tech collection). Artifact chips do not confer Set membership.
• Worn SetIDs are unlimited across the 15 doll slots. Player toggles ActiveSetIDs under ASBP=6 (cost = equipped count per active Set; refuse <2; independent 2→6 ladders). Inactive worn pieces keep Origins / Traits / Artifacts — zero Set ladder power (FS-ITM-004 · TBD-072).
• While a Set is active, only Unique / Apex pieces matching that Set ID count toward its piece thresholds. Pieces from other Sets grant no set bonuses until selected.
• Equip N Unique / Apex pieces whose SetID is in ActiveSetIDs → unlock set bonuses at thresholds (2-piece / 3-piece / 4-piece / 5-piece / 6-piece — exact steps per set).
• Set membership is defined by the Unique / Apex item’s Set ID + piece index — not by the socketed Artifact. Legendary fail-closed. Rare and below cannot host Artifacts.
• Mixing Unique / Apex pieces from different Sets on different slots is allowed for collection / swapping — only Sets in ActiveSetIDs feed thresholds under ASBP=6; inactive worn pieces keep Origins.
• Weapons in all four loadout weapon slots plus Wrist Melee and Physical Shield can contribute if those Unique / Apex items match that Set ID.
• Set bonuses are designer-authored packages (skills, auras, gunfeel-legal combat buffs, resists, tentacle synergy) — never retune Aim Assist baseline or camera verbs.

Artifacts vs Other Socketables

• Gems / Jewels / Phonon Shards — fill normal sockets; Chords need white/gray bases.
• Artifacts — fill the single Artifact socket on Unique / Apex paper-doll items (chip power). Set bonuses come from Unique / Apex item pieces, not the chip.
• Legendary — fixed named item power; no Artifact socket; never a Set piece. Unique — fixed named item power; Artifact socket unless disabled; may be standalone or a Set piece.

Artifact catalog (names, Set IDs, bonus ladders) ships as a design data sheet. GDD locks: 15 equipped slots; Artifacts only on Unique / Apex; one Artifact per eligible item; sets = Unique / Apex item pieces (Legendary never); Active Sets under ASBP=6; four weapon loadout slots (guns / melee / Physical Shields); Energy Shield slot = Barrier gear only.
