Research direction

The issue is a high-level design and planning document for integrating WASI 0.3.1 and QuickJS. The scope is large and cross-cutting, involving multiple repositories (Hosta, Hoya). The first step would be to read the linked research document docs/WASI_JS_PLATFORM_PLAN.md and understand the existing hoya-json-v1 and JS main(input, ctx) interfaces. The work involves defining WIT worlds, TypeScript contracts, and integration tests, but the issue is currently on hold pending product review.

Description

状态：暂缓（2026-09-23）

维护者决定暂缓 Hosta 项目及本项关联改造探索，恢复时间未定。本 issue 保持开放用于保存研究，不按已完成关闭。后续路线（WASI 主线、QuickJS 是否保留、Spin/wasmCloud 复用）尚未批准；恢复前须先 review 产品场景和复用/自建证据，再调整验收与 milestones。Wasmtime 不限定在 33，工具链以恢复时实际验证的版本为准。

研究及暂缓决定：Hosta PR #21。下文是暂停前的候选范围，不是当前实施承诺。

目标

为现有 Hosta/Hoya JSON FaaS 定义未来 WASI 0.3.1 component 与 QuickJS 可移植 API 的共用平台契约。保持 Hosta 控制面、Hoya 独立执行引擎，CLI/agent 优先，旧 hoya-json-v1 与 JS main(input, ctx) 可回滚。

设计和官方依据见待提交的 docs/WASI_JS_PLATFORM_PLAN.md（2026-09-23）。WASI 0.3.1 增加 Component Model map<K,V>、implements/external-id，不能把旧 wasm32-unknown-unknown 模块视为兼容；JS 参考 ECMAScript + WinterTC Minimum Common Web API，平台权限仍自定义。

验收标准

版本矩阵区分 WASI、artifact ABI、JS guest API 与 Hoya HTTP 协议；上传、版本、部署与 run 固定 ABI/能力，doctor 报告真实支持级别。
定义版本化 WIT invoke world、JS TypeScript 契约和跨运行时 JSON/错误/日志/cancel fixtures；明确 wasi:http/service 的 HTTP 专用适用范围。
CLI/API 对 component 上传、校验、试跑、发布、调用、回滚提供明确结果和错误；旧 JS/WASM 生命周期继续通过真实 Hoya smoke，无 UI/AI 前置条件。
权限默认拒绝，Hosta 授权与 Hoya 执行策略一致；出站、密钥、持久存储等能力在限额、审计与负例验证后独立开放。
形成冷启动、p95、RSS、构建大小和失败率基线及可复现实验，先 opt-in，保留回滚与弃用窗口。

依赖

Hoya WASI 0.3.1 运行时和 QuickJS API 子 issue；Hosta #3/#10/#13，Hoya #7/#8/#11。此 issue 是规划与未来集成验收，不表示当前支持 WASI 0.3.1 或 WinterTC 全量兼容。
