Taking Turns
Why taking turns isn't enough to share a consumer fairly, how deficit round robin measures turns in work, and how a deliberately simple reference shows that an implementation follows the rules.
Agentic Coding
How agentic coding adds a boundary between the engineer and the program, and why working code must be simplified, described, and constrained.

Reviews worth the interruption
Making changes understandable, giving reviewers useful evidence, and making code review worth the interruption.
