- Around line 78-87: Prevent installing an older package from replacing the
currently active version in the Install flow around packageIdentity and
next.active. Either add a history-only Retain method that updates next.history
without changing next.active, or require an explicit rollback before allowing a
lower version to become active; preserve existing digest-conflict, revocation,
and retention-limit checks.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Install can silently roll back the active version, and history cannot be restored on its own.
Line 86 always writes the installed package to next.active[p.manifest.Key]. The version is not compared with the version that is already active. Line 70 also rejects a batch that contains two versions of the same key. Because of these two rules, a single call cannot restore both the historical version and the active version of a plugin.
The restart procedure in docs/task-plugin-host.md requires the host to reload retained historical packages. Suppose an operator restores 1.0.0 for in-flight tasks and 2.0.0 as the current version. If 2.0.0 is installed first and 1.0.0 second, 1.0.0 becomes active. BindMapped then sends all new tasks to the older package. No error is returned. The same thing happens at runtime when anyone re-installs an older retained package.
Use one of these fixes:
- Add a history-only restore path, such as
Retain(packages ...*Package). This path adds packages tohistoryand does not changeactive. - Reject an
Installcall whose version is lower than the active version for that key, unless the caller requests a rollback explicitly.
Sketch of a history-only restore
// Retain restores historical packages for Resolve without changing routing.
func (host *Host) Retain(packages ...*Package) error {
for {
current := host.state.Load()
next := cloneHostState(current)
total := 0
for _, p := range packages {
if p == nil || p.digest == "" {
return errors.New("invalid task plugin package")
}
id := packageIdentity(p.manifest.Key, p.manifest.Version)
if old := current.history[id]; old != nil && old.digest != p.digest {
return errors.New("task plugin key/version source changed")
}
next.history[id] = p
}
for _, p := range next.history {
total += p.size
}
if total > MaxRetainedPackageBytes {
return errors.New("task plugin retained package limit reached")
}
if host.state.CompareAndSwap(current, next) {
return nil
}
}

已在 b10afca 修复 4320558882：新增 原恢复路径已复现 RED（预期 v2，实际 v1）；修正后的匹配回归、完整 Windows quick（59 Go 包通过、前端 576/0、vet/JSON policy/typecheck）、生产构建/Tailwind、Go 格式与测试镜像均通过。已正常合入最新 main，完整 PR 差异为 13 文件；目录、M01 和 JS VM 未混入。历史 Windows service 时序失败仍保留为未解决项。当前 HEAD 的 Ubuntu CI 和精确全量审查覆盖继续核验。 |

- Around line 65-67: Update the simulated restart flow in the test to call
Host.Retain instead of restarted.Install, preserving the existing error
assertion and verifying that the persisted binding still resolves to the pinned
1.0.0 package.

当前 HEAD 当前提交 CI #39470628566 通过；稳定观察为 2026-10-20 19:14:53.474 至19:45:25.659 UTC，约30分32秒。到期完整核查评论新增/编辑、HEAD、覆盖和CI，未发现新的有效意见；不声称对窗口内每个瞬时状态进行了观测。PR保持13文件，工作树无遗漏修改。本轮实现和复审完成，保留未合并状态。 验证边界仍保留：历史Windows进程恢复时序失败未归因；真实外部数据库、JS隔离、多节点及真实provider未验。本轮不包含目录/JS VM或资金mutation。 |
📝 变更描述 / Description
向 main 交付版本固定的 Task Plugin 内部宿主基础：校验完整数据包摘要，原子发布路由与版本，保存任务私有绑定，并提供受限 HTTPS 读取和经宿主验证的用量事实。source 不执行；公开插件路由、目录管理和 JS VM 分阶段交付。
补载历史包使用新增 Host.Retain，保持当前活动版本与路由。例如当前选择 v2 时补载 v1，旧任务仍解析 v1，新任务继续使用 v2。Host.Install 明确激活所选版本，包括操作员主动回退；摘要冲突、撤销、64MiB保留上限和CAS批次原子性不变。
🚀 变更类型 / Type of change
🔗 关联任务 / Related Issue
延续 PR #63 的宿主基础向 main 交付；历史恢复修正对应 review https://github.com/MAX-API-Next/MAX-API/pull/65#discussion_r4320558882。持久化目录沿既有后续计划单独交付。
✅ 提交前检查项 / Checklist
📸 运行证明 / Proof of Work
来源边界：对照公开New API行为后，沿MAX原有Host与taskusage契约独立实现历史恢复接口；没有移植上游JS运行时、代码、依赖或计费权威。
后续仅补充 SQLite 测试覆盖（审查4328210837）：先激活v2，再用Retain恢复持久化任务的v1包，验证历史版本/摘要和新绑定v2；原资金与effect断言逐字保留。旧Install路径RED，新恢复路径GREEN（model25.829秒）、model vet和镜像通过。生产源码、依赖和前端构建输入未变，沿用上述完整quick及构建结果；最新HEAD仍需独立完整Ubuntu CI和full review。
当前 HEAD
edb3d839319d703b6236629f0a37a9978e004fb1的 Ubuntu CI #39470628566 已通过：完整 Go 检查59包通过/36包无测试（1包缓存）、service96.144秒，前端576/0、typecheck、两处生产构建、vet和JSON policy通过。全量复审精确覆盖当前HEAD且无待修问题；按既有流程进行稳定观察。历史Windows失败继续保留。
