A small reference notebook
Notes on keeping useful observations and checking a small piece of work.
This notebook collects short explanations that are useful to revisit. Each note focuses on one small question, with plain navigation and local resources.
A useful observation begins with a small question. Decide which result would help answer it before choosing a tool. A short question makes it easier to collect enough information without gathering unrelated material that will be difficult to review later.
An action finishing is useful evidence, but the intended result deserves its own check. Review the part that another person will use. A working link, a readable page or a clear status can reveal a problem that was not visible while the action was running.
