# Overview

The architecture page names a role after the library profession: the **librarian** *binds it into order*. It scrapes the repository, derives concepts with their sources, classifies them, links them with typed relationships, audits, and hands off for review. Like a real librarian it catalogues without vouching: facts about the repository, never verdicts about truth. It runs often, including on a schedule, and starts each run from its [work list](work-list.md).

The `ktl-librarian` skill plays the role ([ktl-librarian skill](../playbooks/ktl-librarian-skill.md)). It writes the bundle only through [the pen](the-pen.md), which marks each concept it creates `status: draft` until a person confirms it through the curator.

The data-management sense of the word *curator* is the librarian's job. The [curator](curator.md) is the museum sense.
