[hardware] Draft Meshtastic and LoRa control-message inventory

[FlowmemoryAI]

Objective

Draft a compact inventory of possible Meshtastic/LoRa control messages and explicitly rule out high-bandwidth payloads.

Allowed folders

• hardware/
• docs/SECURITY_MODEL.md only for concise authentication/adversarial-channel notes
• docs/ARCHITECTURE.md only for a short cross-link

Forbidden folders

• contracts/
• services/
• apps/
• crypto/
• research/
• Firmware implementation, radio integration code, production deployment config

Acceptance criteria

• Message candidates are grouped by purpose: status ping, compact receipt reference, operator command, field diagnostic, emergency signal.
• Each candidate includes approximate payload shape and why it fits low bandwidth.
• The document names authentication, replay, spoofing, and loss/retry risks.
• No firmware or app UI is implemented.

Risk level

Medium

Recommended worktree/agent

E:\FlowMemory\flowmemory-hardware / Hardware Agent

Scope guard

Do not design Meshtastic/LoRa as normal internet bandwidth or as a heavy artifact transport.
