Filtrum

Filtrum is a component that selects and prioritizes content for a user based on their preferences, declared goals, personal characteristics, and current condition.

Its purpose is not only recommendation in the commercial sense, but orientation: helping the user move through an information-dense environment without being pulled apart by noise, manipulation, doom loops, or irrelevant stimuli.

Filtrum should be able to combine long-term signals (values, interests, sensitivities, working style) with short-term signals (fatigue, overload, urgency, focus window, emotional state, current task).

A strong interface for Filtrum would be a browser extension that cooperates with the node client. It could mark, rank, suppress, summarize, or defer content while the user browses, turning the web from an undifferentiated stream into a navigable field.

The filtering logic should remain inspectable and user-steerable. The user should be able to understand why something was elevated, muted, delayed, or hidden, and to switch between modes such as exploration, deep work, recovery, or threat awareness.

Promote to: proposal or requirements document when personal filtering, browser integration, and user-state modeling are designed.
