 - Visual package record `ShipAuthoring` (`aetheria.ship_authoring`): ModelAsset (GLB), Anchors, SchematicLines, Joints: Assets/Scripts/ServerShared/ShipAuthoring.cs:8-66.
 - `ShipAnchor` fields: Id (the hardpoint's `Transform` string), Role, ModelNodeId, ParentId, Order, Joint: ShipAuthoring.cs:39-55. Roles vocabulary: map-icon, hull-collider, shield, tractor, thruster-emitter, weapon-mount, weapon-muzzle, radiator-mesh: ShipAuthoring.cs:71-76. No size, class, or envelope field exists on an anchor.
 - Which hardpoints get a visual anchor: `MountRole`: Thruster -> thruster-emitter, Radiator -> radiator-mesh, Energy/Ballistic/Launcher -> weapon-mount; every other type (Reactor, Shield, Sensors, ControlModule, Tool, Thermal, WarpDrive) is internal and "no anchor may take its id": ShipAuthoring.cs:78-83, 319-327. Each weapon hardpoint needs at least one weapon-muzzle anchor parented to it: ShipAuthoring.cs:341-343.
-- Hardpoint footprint on the grid and the mount are separate: hardpoint cells are validated inside the hull and non-overlapping (ShipAuthoring.cs:300-318); the anchor is a model node bound by id. The Blender add-on derives the hardpoint `Position` from the mount object's origin cell (`mounted_position(cell_at(origin...))`, tools/blender/aetheria_ships/__init__.py:249-256) and adds a default muzzle half a metre along the facing (`MUZZLE_OFFSET = (0,-0.5,0)`, __init__.py:203). Docs: docs/moddable-ship-authoring.md ("Gameplay cell occupancy remains the authored HullData.Shape ... strokes do not decide armor or mount footprints"; Forbidden writers: Blender object names, prefabs, generated rows may not decide hardpoint type or footprint).
+- Hardpoint footprint on the grid and the mount are separate: hardpoint cells are validated inside the hull and non-overlapping (ShipAuthoring.cs:300-318); the anchor is a model node bound by id. The Blender add-on keeps the two spaces apart: Add Weapon creates the layout row at `HardpointData`'s default `Position` and the author sets it in the layout panel; Mirror Mount mirrors the row within the schematic and the object within the model; Package moves no row (tools/blender/aetheria_ships/__init__.py, `_add_mount`, AETHERIA_OT_mirror_mount). Add Weapon also adds a default muzzle half a metre along the facing (`MUZZLE_OFFSET = (0,-0.5,0)`, __init__.py:208). Docs: docs/moddable-ship-authoring.md ("Gameplay cell occupancy remains the authored HullData.Shape ... strokes do not decide armor or mount footprints"; Forbidden writers: Blender object names, prefabs, generated rows may not decide hardpoint type or footprint).
 - Add-on mount entry: "Add a weapon mount and its first muzzle at the 3D cursor, with a layout row" (__init__.py:~310); the layout row carries kind, mount id, rotation, footprint string like `##/##` (docs/moddable-ship-authoring.md). The add-on only creates weapon mounts via that operator; thrusters/radiators are mesh objects tagged by role (docs).
 - Rig: `ShipJoint` {Id, Parent, Axes, Min, Max}: ShipAuthoring.cs:27-37; `ValidateRig` and `RigChains` (ShipAuthoring.cs:344, 370-471). `ShipModCatalog.BindRig` checks the record's joints and each mount's Joint equal the GLB's nearest-ancestor-joint; a thruster or radiator mesh may not sit under a joint (follow-up gimballed-thrusters): Assets/Scripts/ServerShared/ShipModCatalog.cs:209-250.
 - Unity binding: `ShipModVisual.LoadAsync` loads the GLB via glTFast and builds `Anchors` Id -> Transform: Assets/Scripts/Gameplay/ShipModVisual.cs:30-65. Legacy prefab path: `EntityInstance` has `RadiatorHardpoint[]`, `ThrusterHardpoint[]`, `WeaponHardpoint[]` arrays matched by transform name to `HardpointData.Transform` (EntityInstance.cs:23-25, 251-265); `WeaponHardpoint` is only `Transform[] FiringPoint`; `ThrusterHardpoint` is an invisible `MeshRenderer Emitter` that shapes exhaust particles (ThrusterHardpoint.cs); `RadiatorHardpoint` is a `MeshRenderer Mesh`.
