[hardware] Prototype NFC memory cartridge v0

[FlowmemoryAI]

Objective

Prototype the NFC Memory Cartridge v0 concept using passive tags and off-the-shelf readers for physical memory pointers, labels, and cache workflow markers.

Allowed folders

• hardware/memory-cartridges/
• hardware/flowrouter/ only for reader slot and measurement references
• docs/SECURITY_MODEL.md only if cartridge threat assumptions change

Forbidden folders

• contracts/
• services/
• apps/
• crypto/
• Secret-bearing hardware tokens
• Production secure element design
• Final cartridge CAD unless NFC/material measurements are sufficient

Acceptance criteria

• Cartridge v0 schema and tag content limits are documented.
• NFC read-range measurements through candidate print materials are planned or recorded.
• Tag cloning, stale pointer, label spoofing, and operator-confusion risks are covered.
• The doc explicitly forbids private keys, seed phrases, credentials, raw AI memory, and sensitive payloads on passive tags.
• No production secure-hardware claim is made.

Risk level

Medium
