Domain Iot

This is a Layer 3 domain constraints guide that maps IoT realities (unreliable networks, power limits, physical security risks) directly to Rust design decisions. You get constraint tables showing why offline-first matters, when to use no_std versus tokio, and how to think about MQTT QoS levels in terms of battery life. The trace-down approach is helpful: it connects "network can fail" to actual crate choices like rumqttc with exponential backoff. Covers both Linux gateways and MCU devices, which is the right scope since IoT spans that range. The common mistakes table is honest about what kills devices in production (always-on radios, no local buffering). Use this when you need to justify architectural choices for connected devices, not just implement MQTT.

Layer 3: Domain Constraints

Domain Constraints → Design Implications

Domain Rule	Design Constraint	Rust Implication
Unreliable network	Offline-first	Local buffering
Power constraints	Efficient code	Sleep modes, minimal alloc
Resource limits	Small footprint	no_std where needed
Security	Encrypted comms	TLS, signed firmware
Reliability	Self-recovery	Watchdog, error handling
OTA updates	Safe upgrades	Rollback capability

Critical Constraints

Network Unreliability

RULE: Network can fail at any time
WHY: Wireless, remote locations
RUST: Local queue, retry with backoff

Power Management

RULE: Minimize power consumption
WHY: Battery life, energy costs
RUST: Sleep modes, efficient algorithms

Device Security

RULE: All communication encrypted
WHY: Physical access possible
RUST: TLS, signed messages

Trace Down ↓

From constraints to design (Layer 2):

"Need offline-first design"
    ↓ m12-lifecycle: Local buffer with persistence
    ↓ m13-domain-error: Retry with backoff
