[hardware] Define FlowRouter v0 research scope and non-goals

[FlowmemoryAI]

Objective

Create a tight hardware scope note for FlowRouter v0 that separates research, field tests, firmware/electrical work, enclosure work, and operator controls.

Allowed folders

• hardware/
• docs/ARCHITECTURE.md only for a short cross-link
• docs/SECURITY_MODEL.md only for hardware threat assumptions
• docs/DECISIONS/ only if a durable decision is needed

Forbidden folders

• contracts/
• services/
• apps/
• crypto/
• research/ except cross-link references
• Production hardware BOM procurement, production firmware, deployment procedures

Acceptance criteria

• A v0 hardware scope document exists under hardware/.
• It names explicit non-goals, including no heavy data over LoRa/Meshtastic and no production device commitment.
• It identifies the smallest useful proof-of-concept questions.
• It includes open risks for identity, physical tampering, and operator controls.

Scope guard

Keep this research/specification-only. Do not start production hardware or deployment work.
