- [Establishing that the hardware is shared](https://comp4020-agentic-coding-studio.github.io/comp4020-ass2-marcuszorian/lectures/week-09/): Colocation as a precondition every shared-hardware channel depends on, and as a problem a provider can defend on its own terms
- [The leakage taxonomy](https://comp4020-agentic-coding-studio.github.io/comp4020-ass2-marcuszorian/lectures/week-10/): Putting one rubric under seven individually-argued channels, and attaching a number to what each of them actually reveals
- [Closing a channel in software](https://comp4020-agentic-coding-studio.github.io/comp4020-ass2-marcuszorian/lectures/week-11/): Constant-time programming as a discipline, and what it costs to actually practise it
- [Choosing which channels to defend](https://comp4020-agentic-coding-studio.github.io/comp4020-ass2-marcuszorian/lectures/week-12/): The closing lecture — turning a semester of separately-argued channels into one design method with a stated stopping point
- [People](https://comp4020-agentic-coding-studio.github.io/comp4020-ass2-marcuszorian/people/): Who teaches the course, and how to reach them.
- [Idris Fenn](https://comp4020-agentic-coding-studio.github.io/comp4020-ass2-marcuszorian/people/idris-fenn/): Tutor. Runs the acoustic, cache, optical and thermal weeks, and half the weekly Bench sessions.
- [Marisol Quaye](https://comp4020-agentic-coding-studio.github.io/comp4020-ass2-marcuszorian/people/marisol-quaye/): Convenor. Works on power and electromagnetic analysis, and is responsible for the shape of the semester.
