The Knowledge screen in Craftspace ## A page A page is markdown with a title and an icon. Pages nest, and the tree you see in the app is the tree on disk when a space is backed by a repository. Pages come in kinds. An ordinary page, a **decision** (one hard-to-reverse call, with its context and its consequences), a **playbook** (a procedure written as steps), a **meeting**, a **table**. The kind changes how it is rendered and how agents are told to use it, not where it lives. ## A space A space is the **permission boundary**, not a folder. There are two sorts: * **Shared spaces** are org-wide. One per project, named after it, readable and writable by every member. An organisation can have as many as it has projects. * **A personal space** belongs to one member. Everyone gets one when they join. Choosing where to write matters more than it looks: a second project's context in another project's space is how a brain stops being trustworthy. With one shared space there is no choice to make. With several, write to the one whose name matches the project. ## Areas Inside a space, the top level is **Areas**, and one Area owns exactly one page. That page is a glossary spine: one line per term, saying what the term *is*. A term that outgrows its line graduates to its own page beside it. The rule that keeps this working is boring and load-bearing: **the filename is the entry's identity.** Search before you write, and edit the page that already covers the topic. A differently named second page is a duplicate, not an update. ## Gotchas * **A gotcha is not a page.** It belongs under the `Gotchas` heading of the page for the feature it bites, so whoever reads about that feature meets it in place. A gotcha nobody thinks to search for is a gotcha nobody reads. * **Empty spaces read as templates.** A space seeded with folder pages and nothing in them tells a new member this is a filing system rather than something to write in. Put one real page in before you invite anybody.
