Jakub Zych 6cfa0c55d2 refactor: drop 12 runtimes, keep Claude, Codex, OpenCode, Cursor, ZCode, Antigravity
Removes kilo, kimi, kimi-code, copilot, windsurf, augment, trae, qwen, hermes,
cline, codebuddy and pi end to end: capability descriptors, installer branches
and converters (bin/install.js 14.9k -> 11.2k lines), TypeScript converters,
hook surfaces and runtime homes, review lanes qwen/kimi-code, the two pi
migrations, Kimi payload normalization in the hook guards, dead hostBehaviors
vocabulary, launcher home probes, fixtures, runtime-specific tests and the
prose that presented them as supported.

Installer output for the six kept runtimes is byte-identical to before the
prune. The Kimi tool-vocabulary tests in workflow-guard, read-guard and
read-injection-scanner are left in place pending a decision.

title: Embeddable Orchestration System (Host-Integration Interface)
group: v1.7.0 Features
---
**Purpose:** Express every host integration against one public, versioned contract (ADR-1239 Phase A, #1690) instead of bespoke per-host wiring, so onboarding a new host becomes additive descriptor work.
**Behavior:** The interface exposes six interface points (`command`, `dispatch`, `model`, `hooks`, `state`, `artifact`), eight negotiated axes, and a `PROTOCOL_VERSION` handshake that negotiates down to `min(host, engine)`. In 1.7.0, 14 runtimes were migrated onto the interface via imperative adapters (OpenCode #2087, Cursor #2089, Cline #2090, Hermes #2091, Qwen #2092, Kilo #2093, Trae #2094, Kimi #2095, Antigravity #2096, Augment #2097), a declarative adapter (Codex #2088), plus full lifecycle-hook wiring for CodeBuddy (#2098), GitHub Copilot (#2099), and Windsurf (#2100). Descriptors gained an `extensionEvents` vocabulary (#1946), and `/msd-surface` now reproduces a runtime's agent output byte-for-byte from the installer's descriptors (#1575).
**New runtimes:** ZCode (Z.ai — Agentic Development Environment for GLM-5.2, #1925) and a repo-local VS Code extension driven through the adapter (#2103). The retired Gemini CLI now redirects to Antigravity CLI, its official successor (#1928).
