Reusable discovery, scheduling, execution, and receipt contracts for Harn tests

Host capability exposing the harn-rules declarative rule engine to Harn (`rules.search` / `rules.report` / `rules.apply`).

Shared outbound workflow server core for Harn adapters

Language Server Protocol implementation for Harn

Debug Adapter Protocol implementation for Harn

Linter for the Harn programming language

Downloadable on-device prompt-injection classifier for Harn (Layer 2)

Declarative structural rule engine for Harn — rule model, pattern compiler, and matcher built on the harn-hostlib tree-sitter machinery.

Opt-in code-intelligence and deterministic-tool host builtins for the Harn VM

Transport-neutral library for the CAR daemon JSON-RPC dispatcher (used by car-server and tokhn-daemon)

c ffi bindings for tailscale-rs

Multi-channel messaging (iMessage + Slack) for the CAR daemon — approval transports (inbound poller/orchestrator, Slack wire parsing, per-channel config/allowlist/pairing) AND the general outbound send surface backing the runtime's messaging.send tool. Extracted from car-server-core (#418) to cut its test-binary link footprint.

Shared host-state + channel/approval types for the CAR daemon, lifted out of car-server-core so messaging/parslee/coder can extract without a dependency cycle (#418)

Shared logic for FFI bindings (NAPI, PyO3) — JSON wrappers for verify, multi-agent, scheduler

Natural-language → validated car-workflow manifest builder for Common Agent Runtime

Declarative multi-stage workflow orchestration for Common Agent Runtime

Task scheduling and background execution for Common Agent Runtime

Detection of installed agentic CLIs (Claude Code, Codex, Gemini) for the Common Agent Runtime.

Umbrella entry point for external Rust consumers of Common Agent Runtime

Multi-agent coordination patterns for Common Agent Runtime

Meeting capture and persistence on top of car-voice — multi-source sessions, .car/meetings/ on-disk format, segment ingest

OS-level screen capture, accessibility inspection, and input synthesis for Common Agent Runtime

Voice I/O capability for CAR — mic capture, VAD, listener/speaker traits

Built-in commodity agents for Common Agent Runtime

External code discovery + indexing for Common Agent Runtime

Sandboxed execution surface for CAR — process isolation primitives for untrusted agent steps

Parslee platform integration for the CAR daemon — OAuth session (auth), entitlements/capability discovery, M365 docs/search, and the parslee.* tool surface. Extracted from car-server-core (#418 Phase 2).

Remote MCP connectors for the Common Agent Runtime — connect to remote MCP servers over HTTP, register their tools, and route calls through CAR's governance layer (validator, policy, eventlog).

Browser automation and perception pipeline for Common Agent Runtime

Active planner for CAR — generates, scores, and selects proposals via inference
