Use cases

What builders ship on Calyx.

The same four verbs power very different systems. Each use case below leans on one verb and proves one part of the trust discipline — grounded, no-flatten, fail-closed — on real work.

Use cases with proof

A query sends sightlines toward a dim, unresolved constellation; a cyan guard ring holds at the boundary and no bright kernel forms.
Compose Grounded RAG that refuses When the evidence does not support an answer, the system holds at a fail-closed guard instead of bluffing. No kernel blooms until the sources back it, and every answer that does ship carries a citation trail. Ward holds generation closed on ungrounded queries; Ledger records the sources behind each answer.
Small constellations filed into an indigo archival lattice; a recall sightline draws one stored constellation forward so it glows cyan again.
Measure Durable AI memory Each input is kept as a distinct constellation in durable memory and recalled grounded, rather than flattened into one opaque blob. Distinctions stay distinct, so recall returns meaning instead of an averaged smear. Aster stores each input as its own constellation; recall is by association, not by a single collapsed vector.

More to come

Knowledge tracing is next.

Knowledge tracing — measuring which concepts a learner actually grasps versus fluent pattern-matching — runs on the Differentiate verb. We will publish its live demo here once the proof is real, not before. We would rather show an empty space than a staged one.
