bifrost vs CALM
bifrost: Bifrost is a Rust-based static analysis toolbox designed for AI coding harnesses, editors, and large repositories. It provides a shared intermediate representation for multiple programming languages, enabling cross-language structural queries and navigation.; CALM: CALM (Coding Agent Liveness Map) provides AI coding agents with a live, graph-verified map of the codebase, enabling them to understand dependencies and structural relationships before making changes. This ensures safer and more accurate code edits, preventing common pitfalls like breaking call sites or critical components due to lack of visibility.

Features
bifrost01One multi-language Intermediate Representation (IR) to normalize source structure for cross-language analysis.
02Powerful query language (JSON CodeQuery or Rune Query Language) for finding language-neutral code shapes and traversing code relationships.
03Built for agents and editors, exposing structured MCP tools to coding agents and LSP features to editors.
04Designed for active repositories with snapshot isolation, incremental updates, and content-based caching for responsive analysis.
CALM01Real-time, Graph-Verified Codebase Map: Provides full call graphs for 13 languages out of the box (24 languages parsed in total), showing actual dependencies rather than similarity guesses.
02Hard Safety Gates on Write Path: Enforces hash-verified and syntax-checked edits, with hub/high-risk symbols requiring explicit confirmation and review of callers before changes are committed.
03Confidence-Graded Call Edges with Compiler Verification: Call edges are confidence-graded (textual → inferred → resolved → formal), with SCIP/LSP overlays upgrading best-guess edges to compiler-verified ground truth for 12 languages.
04Automated Codebase Health Reporting: Generates fitness reports based on metrics like hub concentration, dead code rate, complexity, and architectural boundary violations, queryable mid-session or enforceable in CI.
05Local-First and Privacy-Preserving Operation: Runs entirely on your machine with no code leaving for indexing or editing, using an MIT license and vendored embedding models for offline use.

Use Cases
bifrost↳Enabling AI coding harnesses with structural code intelligence.
↳Providing advanced LSP features (definitions, references, hover) to editors like VS Code across multiple languages.
↳Performing cross-language static analysis and structural queries on large, mixed-language repositories.
↳Automating reproducible code analysis workflows via CLI and shell scripts.
CALM↳Empowering AI agents to safely refactor and edit code directly, by providing a deep understanding of code dependencies and impact.
↳Ensuring code quality and architecture compliance in CI/CD pipelines, by automatically flagging dead code, high-complexity functions, and boundary violations.
↳Onboarding developers to new codebases or areas by offering an interactive, live map of the project's structure and hotspots.
↳Facilitating secure and validated code modifications within various IDEs and AI client environments, preventing unintended breakages.
