Framework-neutral (vanilla TS + DOM) visual editor for @wildwinter/expr expressions: a hybrid pill-strip + AND/OR tree builder with a raw-text fallback, property picker, and live validation. Scopes, properties and functions come from an injected Dialect +

Scope registry / runtime state container for @wildwinter/expr: owned property scopes + foreign (host-resolved) scopes, save/load, and the scopeRegistrySpec interop format. Produces the EvalContext and ExpressionSchema that expr consumes.

Matched-constraint specificity: score how many atomic constraints in a @wildwinter/expr condition are actively holding it true. Shared by Storylet Studio (storylet draw priority) and Patter (dialogue best-match).

Agnostic expression engine: parse, unparse, evaluate, and serialise a small condition/effect expression language. Scopes and built-in functions are injected via a Dialect.

Patter reference runtime: load a bundle and play dialogue - flows, selectors, choices, jumps, effects, properties. Built on @wildwinter/expr + scoperegistry.

The shared shell for the editor family (Patterpad, Storylet Studio): the app-agnostic design-token grammar, the per-entity colour hash, and the vanilla-TS DOM primitive. Two palettes, one grammar - each app supplies its own palette/fonts over these tokens

The Patter dialect for @wildwinter/expr (scopes shared/scene/flow, built-in functions), an ExpressionSchema builder from property declarations, and the inline {@ref} interpolation helpers (spec §16).

An agnostic version control wrapper library for game development tools.

A simple storylet framework for Ink.
