What does it mean that the weekly review as safety net?

A weekly review catches anything your daily capture missed — it is the redundancy layer that keeps your entire epistemic system trustworthy.

Example: You capture thoughts all week — voice memos in the car, quick notes between meetings, ideas jotted at 11pm. On Sunday morning, you sit down for 45 minutes and discover: a half-formed project idea that never got a next action, a commitment you made on Tuesday that slipped out of your task list, and three notes that are actually about the same problem from different angles. Without the review, those items rot. With it, nothing falls through.

Try this: Block 45–60 minutes this week for your first weekly review. Use the three-phase structure: (1) Get Clear — process every inbox to zero, write down anything still in your head. (2) Get Current — review your calendar (past two weeks, next two weeks), update your active projects and next actions. (3) Get Creative — look at your someday/maybe list and ask what you want to make real. When you finish, write one sentence: 'The thing I would have lost without this review was ___.' That sentence is your proof of concept.
