Committing things to long-term memory means moving knowledge from temporary, fragile link not tracked into durable storage that you can reliably retrieve later. This is the opposite of caching the ideas in your head or context stuffing, where you only need the information for the duration of a task.
Techniques like spaced repetition, link not tracked, and link not tracked help make this transfer stick by forcing repeated, link not tracked — a link not tracked — that strengthens the underlying memory traces over time.
