Parser, AST, and type checker for the Harn programming language

Glob pattern matching primitives for the Harn programming language

Canonical file-language registry (names, extensions, file names, structural support) shared by the Harn runtime and host library.

Tokenizer with span tracking for the Harn programming language

Canonical high-confidence secret pattern catalog shared by the Harn runtime redaction/scan paths and downstream host consumers.

Canonical typed Harness capability method contracts

Unified time + sleep abstraction for the Harn runtime, CLI, triggers, cron, and harn-cloud.

Harn grammar for tree-sitter

Runtime-installable builtin signature registry. Decouples harn-parser (consumer) from harn-vm (producer) without a dependency cycle.

#[harn_builtin] proc-macro: emits a runtime registration entry plus a parser BuiltinSignature from a single annotated function.

Shared type definitions for Harn builtin signatures (BuiltinSignature, Param, Ty). Consumed by both harn-parser and harn-vm so signatures stay cycle-free.

Crate-local source collection for Harn compiler and check fingerprints

Source contributions and compiled fingerprint composition for Harn crates

Optional provider-native session sources for ai-hist: Claude web, Codex cloud, Devin cloud and Cursor Cloud Agents.
