runx-runtime

Native Rust runtime for governed runx execution.

This crate owns the canonical local orchestration path for Rust-backed runx: skill execution, graph execution, harness replay, host reporting, sandbox preparation, receipts, history projection, adapters, and domain-free effect orchestration. Pure parser, core, contract, receipt, and domain crates remain upstream.

Current slice:

• parses a local graph with runx-parser
• plans sequential/fanout transitions with runx-core
• runs cli-tool skills behind the cli-tool feature
• emits receipts and validates the parent receipt tree with runx-receipts
• exposes native skill, doctor, list, history, MCP, registry, config, policy, tool, and dev command support through runx-cli

Adapter families remain feature gated:

• cli-tool
• mcp
• mcp-http-server
• a2a
• agent
• catalog
• external-adapter
• http

a2a is contract-defined but not enabled in runx-cli; the CLI enables cli-tool, catalog, mcp, mcp-http-server, external-adapter, agent, and http.

Doctor

The native Rust doctor API is wired into runx-cli for the read-only diagnostic surface. It must not shell out to npm or TypeScript for canonical local behavior.

This crate currently ports the read-only fixture-backed diagnostics:

• runx.tool.manifest.removed_format
• runx.tool.fixture.missing
• runx.skill.fixture.missing
• runx.structure.file_budget.exceeded
• runx.structure.cross_package_reach_in

Deferred doctor families remain owned by follow-up slices:

• runx doctor --fix repair writes
• diagnostic catalog, --list-diagnostics, and --explain
• official skills lock freshness
• tool manifest stale source and schema hashes
• packet index diagnostics
• graph packet path validation
• receipt proof health
• policy health
