Basics

• B1. I have applied the proper label & proper branch name (e.g. norswap/build-system-caching).
• B2. This PR is not so big that it should be split & addresses only one concern.
• B3. The PR targets the lowest branch it can (ideally master).

Correctness

• C1. Builds and passes tests.

• C2. The code is properly parameterized & compatible with different environments (e.g. local, testnet, mainnet, standalone wallet, ...).

• C3. I have manually tested my changes & connected features.

• C4. I have performed a thorough self-review of my code after submitting the PR, and have updated the code & comments accordingly.

Architecture & Documentation

• D1. I made it easy to reason locally about the code, by (1) using proper abstraction boundaries, (2) commenting these boundaries correctly, (3) adding inline comments for context when needed.
• D2. All public-facing APIs & meaningful (non-local) internal APIs are properly documented in code comments.
• D3. If appropriate, the general architecture of the code is documented in a code comment or in a Markdown document.
