It supports command arguments, environment variables, working directories, stdin and EOF handling, separate stdout and stderr, exit status, remote deadlines, cancellation, process listing, signals, reconnection, and explicit cleanup. Adds pinned envd protobuf definitions, generated ConnectRPC types, lifecycle handling, protocol tests, unit tests, and credential-gated integration tests. PTY execution is rejected because separate output streams cannot be preserved. The client is not connected to Public API and compatibilityExisting public APIs and E2B execution behavior remain unchanged. The internal package adds exported symbols:

This cleanup path can turn a normal timeout into an error if the process has already exited. Treat CodeNotFound on the tag path as success once the process is gone so TimedOut stays clean.
中文
当进程已经退出时，这个清理路径会把正常超时变成错误。应在 tag 路径上把 `CodeNotFound` 视为成功，让 `TimedOut` 保持干净。![coderabbitai[bot]](https://avatars.githubusercontent.com/in/347564?s=60&v=4){kind=small}

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Construct a non-nil EndEvent for this case.
Line 447 leaves ProcessEvent_End.End nil. handleReceivedEvent returns "received empty EndEvent" before it calls endEventError. The assertion at Line 488 therefore cannot match "process ended without exiting".
Use an empty ProcessEvent_EndEvent to test Exited=false, or change the expected error to test the nil-EndEvent path.
Proposed fix
- {Event: &process.ProcessEvent{Event: &process.ProcessEvent_End{}}},
+ {Event: &process.ProcessEvent{Event: &process.ProcessEvent_End{
+ End: &process.ProcessEvent_EndEvent{},
+ }}},中文
请为该用例构造非 nil 的 EndEvent。
第 447 行使 ProcessEvent_End.End 保持为 nil。handleReceivedEvent 会在调用 endEventError 前返回 "received empty EndEvent"。因此，第 488 行的断言无法匹配 "process ended without exiting"。
请使用空的 ProcessEvent_EndEvent 测试 Exited=false，或者修改预期错误以测试 nil EndEvent 路径。

Bound aggregated process output.
processState.appendData appends every stdout and stderr event to unbounded bytes.Buffer values. A high-volume envd process can therefore grow host memory while its stream remains active. Add a bounded capture policy, expose truncation through Result, and apply the policy to every path that constructs processState.
中文
限制聚合进程输出。
processState.appendData 会将所有 stdout 和 stderr 事件追加到无上限的 bytes.Buffer。因此，高输出量的 envd 进程可能在流保持活动期间持续占用宿主内存。增加有上限的捕获策略，在 Result 中报告截断状态，并将该策略应用到所有创建 processState 的路径。

同意这个无界聚合问题。还需要先确定它与上层 codeexecutor.RunResult 的契约映射：当前公共结果没有 stdout/stderr 截断标记，而本包的 Result 又承诺返回精确输出，因此简单静默截断会造成新的行为不兼容。建议在接入 workspaceRuntime.RunProgram 前明确采用 request 级上限 + 截断状态、超限显式错误，或流式/落盘方案中的一种，并为两个输出流分别覆盖边界测试。
There was a problem hiding this comment.
@liuzengh, agreed. The bounded-capture change must not silently alter the Result exact-output contract.
Before workspaceRuntime.RunProgram uses this client, define one explicit output policy and map it to codeexecutor.RunResult:
- Request-level limits with per-stream truncation status.
- A typed or inspectable output-limit error.
- Streaming or durable output storage.
The selected policy must define stdout and stderr behavior independently. Tests should cover each stream at the limit, one byte over the limit, simultaneous output, and the upper-layer codeexecutor.RunResult mapping.
中文
同意。受限捕获不能静默改变 Result 的“精确输出”契约。
在 workspaceRuntime.RunProgram 接入该客户端前，需要确定一种明确的输出策略，并将其映射到 codeexecutor.RunResult：
- 请求级上限，并分别提供两个输出流的截断状态。
- 可识别的输出超限错误。
- 流式输出或持久化输出。
选定的策略必须分别定义 stdout 和 stderr 的行为。测试应覆盖每个流恰好达到上限、超过上限一个字节、两个流同时输出，以及上层 codeexecutor.RunResult 映射。

Learning: For the Go package `codeexecutor/e2b/internal/envdprocess`, `Result` currently promises exact stdout and stderr output. Do not introduce silent bounded-output truncation. Before connecting this client to `workspaceRuntime.RunProgram`, define an explicit capture policy that maps to the public `codeexecutor.RunResult` contract, which currently has no per-stream truncation marker. The policy options are request-level limits with status, an explicit output-limit error, or streaming/durable storage, with boundary tests for stdout and stderr independently.

这里在完成初始 SendInput / CloseStdin 前尚未启动 event consumer，会产生双向背压死锁：如果远端程序先输出大量数据、随后才读取较大的 stdin，响应流写满后 envd 无法继续排空 stdout，程序阻塞在 stdout；与此同时 SendInput 又会因程序未读取 stdin 而阻塞。我在隔离测试中用 64 MiB 不可压缩输出和 1 MiB stdin 可稳定复现，最终在 2 秒后返回 write stdin: deadline_exceeded。建议在收到 StartEvent 后立即持续消费响应流，并用 startup barrier 协调终止事件与 stdin 初始化，而不是串行化这两个方向；同时补充大 stdin + 大输出的背压回归测试。

Run 是同步、拥有进程执行生命周期的入口；这里在调用方取消或初始 stdin 失败时只通过 defer 断开流，不会终止远端进程。命令仍可能继续产生副作用并占用资源，直到默认 60 秒或调用方设置的更长 remote timeout，这也与 #2521 评审中“取消 RPC 时终止远端进程”的既定要求不一致。建议保留 Start 的 detach/reconnect 语义，但让 Run 在异常返回且已获得 PID 后使用独立的短超时 cleanup context best-effort Kill；PID 尚未返回时也需要唯一 tag 或等价机制处理启动竞态。

这里跳过后，整个 integration suite 仍可在缺少有限 stdin 所必需的 CloseStdin 能力时通过；PR 描述中的真实 envd 0.2.10 验证实际上也因此没有覆盖 RunWithStdin。由于后续 RunProgram 必须保持 Stdin 契约，接入前应明确最低 envd 版本或 production capability gate，并在能力缺失时显式失败或选择有文档的兼容路径，不能把 skip 后的套件通过视为完整兼容验证。

What changed
Adds an internal envd Process client for structured, non-PTY command execution in E2B-compatible sandboxes.
The client supports command arguments, environment variables, working directories, stdin and EOF handling, independent stdout and stderr collection, exit status reporting, remote process deadlines, caller cancellation, explicit process cleanup, and reconnectable process handles.
The transport now requires HTTPS for remote endpoints. Credentialless HTTP remains available for loopback-only development, while the default HTTP client rejects cross-host redirects and HTTPS downgrade redirects.
The PR also includes local protocol tests and credential-gated integration tests covering the imported envd Process RPC surface.
Why
E2B currently routes arbitrary program execution through the Code Interpreter
/executeendpoint, conflating code evaluation with general process execution. The envd Process interface provides the lifecycle and streaming semantics needed byRunProgram.This PR establishes a protocol-correct internal adapter before changing the existing execution path. The envd protobuf definitions and generated Connect types are pinned to a known E2B infra revision to prevent handwritten framing and protocol drift. ConnectRPC handles wire encoding and streaming while retaining the standard Go HTTP client as the transport.
Because envd process lifetime is independent of a stream attachment, caller cancellation disconnects the local attachment without implicitly killing the remote process. The remote process remains bounded by its envd deadline and can be terminated explicitly through the process handle.

0.2.10. TheProcess.CloseStdinandRunWithStdincases were skipped through version-backed capability detection because that deployment does not implementProcess.CloseStdin; all other Process protocol, timeout, and process-handle lifecycle cases passed. The transport-hardening follow-up was validated by local TLS, credential-policy, and redirect-policy tests; live integration should be rerun after the branch is updated.Notes for reviewers
