scholialang

Scholia helps agentic systems preserve reasoning state, use tools without quality loss, and reduce context cost across long-horizon work. scholialang is the Python reference implementation of the language: the parser, validator, and core primitives that make Scholia traces portable, inspectable, and reusable across sessions.

Scholia v0.6 builds on content-addressed reasoning traces. The v0.6 language keeps the v0.5 closed vocabulary and adds the content-addressed substrate: optional canonical_id hashes, a canonical-id-keyed DAG registry, and the three core lazy-prelude modes hash_only, hash_list, and inline.

It contains the language-level pieces only:

• atom dataclasses
• parser
• validator
• canonical_id hashing
• DAG registry primitives
• lazy prelude rendering
• stable atom IDs
• metadata helpers
• JSON/YAML serializers
• Markdown/XML renderers

Host-runtime concerns such as trace persistence, enrichment, adjudication, and proof-graph bridging live outside this package.

Current v0.6 Scope

scholialang owns the language runtime for the v0.6 scope: the 32-kind closed vocabulary inherited from v0.5, optional canonical_id computation and validation, canonical-id-aware reference resolution, the local DAG registry primitive, and the three finalized lazy-prelude modes. MCP servers, editor clients, host plugins, and public launch pages live in sibling repositories.
