# SOURCES — Paper 04

## External academic anchors

- Extended Mind: stable external resources can under some conditions participate constitutively in cognition.
- Body-schema tool-use research: tools can modify body schema and peripersonal space.
- Prosthetic embodiment: ownership, agency and body representation are separable but interacting dimensions; prostheses can become deeply embodied through sensorimotor integration.
- Tool embodiment studies: a tool may be incorporated functionally or spatially without necessarily acquiring the same status as a biological limb.

## Internal theory anchors

## Deliberate constraints

- Philosophical ontology only.
- No equations or scoring.
- Boundary plasticity does not imply unrestricted self-expansion.
- High coupling does not erase otherness.
- Dependence and control are insufficient by themselves for subject-domain inclusion.
