Combine what you've learned into one real build

Combine JSON inventory validation, a simulated per-device health check, and report design into one build: parse a messy device export, classify every valid device's health across two independent signals, and produce one structured fleet report -- deciding its shape yourself.

Combine multi-device text-config validation, structured fact extraction, and line-by-line comparison into one backup analysis pipeline that safely handles a missing or corrupted backup instead of crashing on it.

Build a data-driven compliance engine that evaluates every device in a fleet against a shared set of policy rules, safely isolating a rule failure caused by missing device data from a device record too malformed to evaluate at all.

Validate a batch of proposed network changes against a device inventory -- without ever connecting to a device or applying anything -- to produce a reviewable, sequenced change plan that flags unknown devices, conflicting requests, and devices that must be excluded.
