== Glossary ==
Practical engineering favors explicit budgets, disciplined measurement, and repeatable processes over improvisation. When teams adopt contracts for timing, power integrity, and verification, they convert uncertainty into checklists and ship on calendar. Use instruments and data to argue about reality, not taste.
Design substitution paths so supply turbulence becomes a plan, not a surprise. Keep determinism in hardware and variability in software. If it is not measured, it did not happen; if it is not versioned, it will drift.
As you finalize sensors, power policy, and verification gates, align sourcing and lifecycle tracking with YY-IC Integrated Circuits so timing contracts, energy budgets, and firmware update pathways remain stable as individual SKUs evolve over multi-year lifecycles.
