Suggested reviewers: Merge Risk: 🟡 Moderate · up to On SQLite deployments, saving settings can store the wrong value for chat connection retention and can wrongly overwrite or preserve prompt-filter settings.

modernc.org/sqlite v1.47.0 database/sql unnamed arguments bind SQLite $N parameters ordinal parameter index source
💡 Result:
**In `modernc.org/sqlite v1.47.0`, `database/sql`’s unnamed arguments are assigned by ordinal, not by matching the numeric suffix of a SQLite `$N` parameter.**
The versioned driver source converts positional values to `driver.NamedValue`s with ordinals `1, 2, 3, …`; execution passes those arguments to the driver’s bind routine. ([raw.githubusercontent.com](https://raw.githubusercontent.com/modernc-org/sqlite/v1.47.0/stmt.go)) SQLite, in turn, treats `$name` as a named parameter, while `?NNN` explicitly denotes the parameter slot numbered `NNN`. ([sqlite.org](https://sqlite.org/lang_expr.html?utm_source=openai))
So for `SELECT $2`, passing one unnamed argument does **not** mean “bind this to slot 2” just because it is the second-style parameter. To target SQLite slot 2, use `?2` or a named argument matching `$2`—and note that `$2` is SQLite’s named form, not its numbered-slot form. The source excerpts retrieved here establish ordinal creation and the handoff to binding, but do not expose the v1.47.0 bind routine’s full mapping logic, so that last named-argument detail is not confirmed from this version’s implementation. ([raw.githubusercontent.com](https://raw.githubusercontent.com/modernc-org/sqlite/v1.47.0/stmt.go))

Use sequential parameter order in the SQLite upsert.
modernc.org/sqlite v1.47.0 binds unnamed arguments by ordinal. SQLite assigns parameter slots by first appearance. Because $131 appears before $129 and $130, SQLite binds the last three arguments incorrectly. The save can persist the preservation flags as codex_ws_downstream_keepalive_slots and use the wrong values in both CASE expressions.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Return a classified continuation error when the shared commit barrier times out.
The local barrier waitNativeWSCommit returns &ResponsesContinuationLostError{Reason: "context_commit_pending"} when nativeWSCommitWait expires. The shared barrier does not. When waitCtx reaches its own deadline, the shared barrier returns the raw context.DeadlineExceeded. The parent request context is still live at that point.
Trigger: another instance holds the Redis pending owner for longer than nativeWSCommitWait. For example, its backend write stalls before it calls CompareAndDeleteRuntimeOwner.
Consequence: the continuation fails with an unclassified context error. It does not get the 409 previous_response_not_found / response_context_unavailable classification that the recovery path depends on. Callers can also mistake this error for client cancellation.
Map the barrier's own timeout to the same error that the local barrier uses. Keep parent cancellation unchanged.

Classify the commit-wait timeout as a lost context, not a 503.
waitNativeWSCommit returns *ResponsesContinuationLostError{Reason:"context_commit_pending"} when the 5-second timer fires. It returns ctx.Err() when the client disconnects. This branch maps every error to a 503 service_unavailable frame. After a client disconnect, the handler writes to a closed connection instead of returning errResponsesWSClientGone. Check the context error first, and return errResponsesWSClientGone for it.

本 PR 旨在避免账号请求并发限制与 WS 连接保留容量耦合导致的连续工具调用断流。
典型场景：上游账号限制为 3 并发，但下游有 4 个并发会话。某个用户的 agent turn 刚结束、正在本地执行工具或等待下一轮时，上游 WS 暂时没有在途请求，却仍承载该用户的聊天上下文和
previous_response_id续链关系。若此时为了接纳其他会话而强制回收这条连接，下一轮工具结果就可能无法沿原连接续链，表现为断流（Codex客户端需要连续重连两次才能恢复），客户端不得不重新发送完整上下文。修改后，请求并发与空闲连接保留分别管理：账号限制为 3 时仍最多处理 3 个请求，但可以按独立设置保留更多等待下一轮的聊天连接。有效续链优先复用原上游连接；确需回收或连接断开时，网关尝试从本地或 Redis 快照恢复工具链上下文，减少客户端重发上下文的需要。
最终实现
store:false、断线重连和 Redis 跨实例恢复；隔离缓存作用域，校验账号与加密内容兼容性，使用提交屏障避免下一轮抢先读取不完整快照。缓存缺失、容量不足等可恢复错误保留下游 WS，允许后续请求继续使用。并发与部署边界
验证
go test ./...全量通过（先构建前端嵌入资源后运行）。git diff --check通过。go test -race ./proxy/wsrelay通过；原生 WS 恢复关键路径go test -race ./proxy -run 'Test(NativeWS|PreviousID)' -count=1通过。Summary by CodeRabbit
