CARITO SMALL GRID HARDPOINT MAP v1.0
================================

Document: SG_Hardpoint_Map.txt
Status: Grid Specification / Non-Negotiable
Applies To: All Small Grid MMF cages, Power Frames, and internal supports

--------------------------------------------------
1. PURPOSE
--------------------------------------------------
This document defines standardized hardpoints, weld zones, clamp zones,
and prohibited areas within the Small Grid (SG) MMF cage.

The Hardpoint Map exists to make shop fabrication predictable,
repeatable, and reversible without compromising platform integrity.

--------------------------------------------------
2. CORE PRINCIPLE
--------------------------------------------------
Hardpoints are standardized.
Engines are not.

All engine-specific structures must attach to approved hardpoints
or Power Frame structures, never directly to the MMF cage envelope
outside approved zones.

--------------------------------------------------
3. REFERENCE FRAME
--------------------------------------------------
All locations reference the SG-MMF cage coordinate system:

- X-axis: Front (+) to Rear (-)
- Y-axis: Left (+) to Right (-)
- Z-axis: Bottom (+) to Top (-)

Origin (0,0,0) is defined at:
- Center of Chassis Interface Plane
- Centerline of cage width
- Bottom plane of SG-SPV

--------------------------------------------------
4. PRIMARY HARDPOINT RAILS
--------------------------------------------------
The SG-MMF cage includes two longitudinal internal rails:

Left Rail:
- Parallel to X-axis
- Offset +Y from centerline
- Extends minimum 80 percent of cage length

Right Rail:
- Parallel to X-axis
- Offset -Y from centerline
- Extends minimum 80 percent of cage length

These rails are the primary attachment points for Power Frames.

--------------------------------------------------
5. SECONDARY HARDPOINT ZONES
--------------------------------------------------
Secondary hardpoints may be provided as:

- Crossmembers
- Shelf supports
- Vertical struts

Rules:
- Must be symmetric where possible
- Must not intrude into service corridors
- Must not reduce SG-SPV envelope

--------------------------------------------------
6. APPROVED WELD ZONES
--------------------------------------------------
Approved weld zones include:
- Hardpoint rails
- Designated lock tabs
- Secondary supports marked as weld-eligible

Welds in these zones must:
- Be cuttable
- Be documented
- Not redefine cage geometry

--------------------------------------------------
7. CLAMP AND BOLT ZONES
--------------------------------------------------
Clamp and bolt zones are preferred over welding.

Approved clamp zones:
- Hardpoint rails
- Flat support surfaces
- Reinforced cage members

Clamps must not crush tubing or distort alignment.

--------------------------------------------------
8. PROHIBITED ZONES
--------------------------------------------------
The following areas are prohibited for welding, drilling, or cutting:

- Cage outer envelope members
- Chassis Interface Plane
- Power Output Plane
- Service Access Plane
- Defined service corridors

Violation of prohibited zones invalidates SG compliance.

--------------------------------------------------
9. ENGINE-SPECIFIC STRUCTURES
--------------------------------------------------
Engine mounts, generator cradles, and motor brackets must:
- Be part of the Power Frame
- Attach only to approved hardpoints
- Remain removable as a unit

No engine-specific geometry may be welded directly to the cage envelope.

--------------------------------------------------
10. UTILITY AND ACCESSORY MOUNTS
--------------------------------------------------
Accessory mounts (controllers, batteries, helpers) may:
- Attach to secondary hardpoints
- Use clamp systems
- Use removable brackets

Permanent mounting is discouraged in baseline builds.

--------------------------------------------------
11. TOLERANCES AND CLEARANCES
--------------------------------------------------
Hardpoints must maintain:
- Alignment tolerance within SG-SPV adjustment limits
- Clearance for service access
- Clearance for future Power Frames

--------------------------------------------------
12. INSPECTION ROLE
--------------------------------------------------
Inspectors may use the Hardpoint Map to:
- Verify approved attachment methods
- Identify prohibited modifications
- Distinguish baseline from experimental builds

--------------------------------------------------
13. DOCUMENTATION REQUIREMENT
--------------------------------------------------
Any use of weld zones must be documented with:
- Location reference
- Purpose
- Removal method

--------------------------------------------------
14. AMENDMENTS
--------------------------------------------------
Changes to this map require:
- Version increment
- Change log entry
- Platform justification

--------------------------------------------------
