Philosophy

Kastalia is named after Hermann Hesse's Castalia, the walled province of pure intellectual play in The Glass Bead Game -- a deliberate signal that the system is meant to treat knowledge not as a pile of documents to be filed away, but as material for a game: something to be combined, recombined and played with across disciplines.

Technically, this philosophical stance shows up as a refusal to commit to any one fixed schema. Where most content-management systems bake a particular domain's structure into their database (a blog has posts and comments; a course platform has courses and lessons), Kastalia's knots and bounds commit to almost nothing -- any knot can, in principle, stand in any relation to any other. The cost of that freedom is that the system gives you very little for free; the benefit is that it never tells you no.
