Mini Lesson: Task Scheduling Basics

Core concept

Task scheduling is about protecting system behavior under contention, not just assigning priorities.

Practical rules

• Keep high-priority tasks short and deterministic.
• Move variable-latency work out of time-sensitive paths.
• Prefer explicit message ownership over shared mutable state.
• Define timeout and retry behavior as part of task contracts.

First review pass

Ask these three questions:

1. Which task owns each shared resource?
2. Which execution path can block longer than expected?
3. Which failure signal tells us starvation or timing drift is happening?
