+# Agent Note: PowerShell CI completion and profile expectations
+
+Status: implemented
+
+English | [中文](2026-09-07-pwsh-ci-observable-completion.zh.md)
+
+## Problem
+
+The [hosted coverage job](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34033367752/job/101605386802) rejects a persistent PowerShell send because it returns `inferred_idle` rather than `stdin_read`. Output silence is a supported bounded inference, not proof that a command finished. The real-shell test also searches output for text present in the echoed command, which cannot independently prove execution.
+
+The [snapshot job](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34033367752/job/101605386868) rejects both PowerShell scenarios despite successful `PWSH_OK` output. Their fixtures omit the headless profile’s policy events and runtime-context message; their prompt and tool-schema pins also describe an older, smaller composition. Hosts without PowerShell skip these cases and cannot detect that drift.
+
+## Decision
+
+The [real-shell test](../../../../packages/terminal/terminal-bash/tests/local.spec.ts) accepts either supported readiness tier, rejects timeout and exit settlements, and observes formatted child output in scrollback to prove environment persistence, current directory, and credential scrubbing. The expected text is absent from the submitted command. A private-file barrier holds execution beyond the silence settlement and releases it only after the next send settles, proving that later output remains observable without extending production timings. Session disposal precedes removal of the private test directory.
+
+The [one-shot](../../../../snapshots/session/pwsh-tool-turn/snapshot.yml) and [persistent](../../../../snapshots/session/persistent-pwsh-tool-turn/snapshot.yml) fixtures and owned header pins are refreshed through the built headless profile with a real PowerShell executable and recorded model replies. Policy events and available tools remain visible in the expectations; the tool result and final answer remain `PWSH_OK` and `DONE`.
+
+## Alternatives considered
+
+- Increase silence or handoff timeouts: this changes latency without making exact readiness deterministic. The [persistent-terminal decision](../feature/2026-07-16-persistent-pty-sessions.md) retains both exact and inferred outcomes.
+- Accept either wait reason without observing execution: echoed input and delayed commands could falsely satisfy the test.
+- Filter policy events or disable inherited headless tools: this hides the assembled profile instead of testing it. The [snapshot-corpus decision](2026-08-24-session-log-snapshot-corpus.md) keeps persisted output and header pins authoritative.
+
+## Consequences
+
+The file-gated case deterministically rejects the exact-only assertion, while the repaired test proves the command’s effects after an inferred settlement. Real PowerShell is required for this evidence; a skipped local run is not validation. Focused built replay checks both Session output and header pins without normalizer changes. Production terminal behavior, timing configuration, and CI routing are unchanged.

+# Agent Note: PowerShell CI 完成信号与 profile 预期
+
+Status: implemented
+
+[English](2026-09-07-pwsh-ci-observable-completion.md) | 中文
+
+## Problem
+
+[托管 coverage 作业](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34033367752/job/101605386802) 因持久 PowerShell send 返回 `inferred_idle` 而非 `stdin_read` 判定失败。输出静默是受支持的有界推断，不是命令完成的证明。真实 shell 测试还在输出中查找被回显命令本身包含的文本，无法独立证明命令执行。
+
+[快照作业](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34033367752/job/101605386868) 在成功输出 `PWSH_OK` 后仍拒绝两个 PowerShell 场景。其 fixture 缺少 headless profile 的策略事件与运行时上下文消息；prompt 和工具 schema pin 也描述了更早、更小的组合。没有 PowerShell 的主机会跳过这些用例，无法发现此类漂移。
+
+## Decision
+
+[真实 shell 测试](../../../../packages/terminal/terminal-bash/tests/local.spec.ts) 接受两种受支持的就绪层级，拒绝超时和退出结算，并在 scrollback 中观察格式化的子进程输出，证明环境持久化、当前目录与凭据清理。预期文本不出现在提交的命令中。私有文件屏障将执行阻塞到静默结算之后，只有下一次 send 结算后才释放，证明后续输出仍可被观察，而不延长生产时序。会话释放先于私有测试目录删除。
+
+[单次](../../../../snapshots/session/pwsh-tool-turn/snapshot.yml)与[持久](../../../../snapshots/session/persistent-pwsh-tool-turn/snapshot.yml) fixture 及其拥有的 header pin 使用真实 PowerShell 可执行文件和已录制模型回复，经构建后的 headless profile 刷新。策略事件和可用工具保留在预期中；工具结果与最终回复仍为 `PWSH_OK` 和 `DONE`。
+
+## Alternatives considered
+
+- 增加静默或前台交接超时：这会改变延迟，却无法让精确就绪变得确定。[持久终端决策](../feature/2026-07-16-persistent-pty-sessions.zh.md) 保留精确与推断两种结果。
+- 接受任一等待原因，但不观察执行：回显输入与延迟命令可能让测试错误通过。
+- 过滤策略事件或禁用继承的 headless 工具：这会隐藏组合后的 profile，而非测试它。[快照语料决策](2026-08-24-session-log-snapshot-corpus.zh.md) 保持持久化输出与 header pin 的权威性。
+
+## Consequences
+
+文件屏障用例能确定性地拒绝仅接受精确就绪的断言，修复后的测试则在推断结算之后证明命令效果。此证据需要真实 PowerShell；本地跳过不算验证。聚焦的构建后回放同时检查 Session 输出与 header pin，不改动 normalizer。生产终端行为、时序配置与 CI 路由均不变。
