Importance: The required Python test-shard and downstream merge-gate cannot pass for Python-changing work while this stale assertion rejects the already-shipped antigravity Steward executor.

Goal And Delivered Outcome

• Outcome basis / optional anchor: Fixes [Bug]: Required Python test-shard rejects the shipped Antigravity steward executor #8028; removes this false failure from the required Python qualification path after the Antigravity executor shipped in feat(chat): support Antigravity (Gemini 4 Argon) as Steward and Chat executor #7832.
• Goal/source and gap: The steward editor intentionally projects steward_executor_endpoints(), but its test still hard-codes ["codex", "dsh"]. The owner now returns antigravity, codex, and dsh, so the required configuration test fails despite correct product behavior.
• Observable before → after, with the validation row that proves it: At a0130633, the focused test fails with ['antigravity', 'codex', 'dsh'] == ['codex', 'dsh']; after this change the same test passes on Python 3.14 and on the CI-matching Python 3.11, as recorded below.
• Issue/task and intended base: Fixes [Bug]: Required Python test-shard rejects the shipped Antigravity steward executor #8028; PR base is loopx-project/loopx:main.

Author Declaration

• Written by: OpenAI Codex model_agent, operating from a user-requested autonomous contribution task. No human reviewed this change before submission; maintainer review is requested.

Implemented against

• Specification and revision: No separate written specification; the existing owner contract steward_executor_endpoints() and the linked issue are the basis. Relevant history: feat(chat): support Antigravity (Gemini 4 Argon) as Steward and Chat executor #7832 and perf(kernel): read the steward endpoint vocabulary without the chat layer #7746 at a0130633723210a5406dca61ee27aa33fe48b3f3.
• Criteria:

• Self-check before submission: Read feat(chat): support Antigravity (Gemini 4 Argon) as Steward and Chat executor #7832, perf(kernel): read the steward endpoint vocabulary without the chat layer #7746, and the current owner/editor implementations; verified the exact assertion failure before the edit; verified the full configuration test file, the owner vocabulary suite, Ruff, Python 3.11, and loopx canary premerge. No product code was changed.

Scope And Continuation

• Completed scope and remaining work: Remove the duplicated executor vocabulary from the test and compare the editor projection to the owning namespace. Complete within this scope.
• Slice boundary / successor: N/A. The production behavior is already correct; no follow-up is required for this defect.

Validation

• Tested revision: 17aa7c92be9fb25ebc7caea5df9d71b14556435d
• Run state: finished
• Input classes: synthetic

Check kind	Result	Public-safe evidence / limitation
unit	passed	tests/capabilities/test_capability_configuration_ui.py: 29 passed on Python 3.14.
unit	passed	Focused regression test passed on Python 3.11, matching CI.
unit	passed	Antigravity vocabulary assertion plus all steward machine-default tests: 10 passed.

static	passed	uv run --extra test loopx canary premerge --from-git-diff --git-diff-base upstream/main: passed, 1 changed file, 0 failures, 0 manual holds.

• Coverage and gaps: The changed test directly exercises the editor field that failed. A broader unrelated Antigravity file run also exposed two existing trusted_owner history-delivery failures; this test-only diff cannot affect those product paths. The full six-shard CI suite is left to hosted qualification.

APPROVE — 当前 exact head 未发现 blocking finding。 我独立复现了旧断言失败，并用有区分度的错误投影确认新断言仍能发现遗漏、多余和重复 executor。

动机

受影响的是为 Steward 配置或相关 Python 变更运行必需验收的贡献者。产品已经把 antigravity 作为合法 executor，与 codex、dsh 一起从 namespace owner 投影到编辑器；旧测试却只接受后两个值。此前正确产品行为也会使测试失败；本 PR 让测试检查编辑器与合法词汇的一致性，并由既有独立测试继续固定已出货的 Antigravity 支持。可观察结果是：同一套配置/owner 测试在 base 为 38 passed、1 failed，当前 head 为 39 passed。它不改变产品配置、默认 executor、权限或模型调用，也不宣称完整 CI 已绿。

这是一个可独立交付的内部维护修复：消除已复现的伪失败，恢复验收路径的信号，而非为了增加测试数量。保留旧列表会继续阻断正确结果；改成另一个三项字面量虽能暂时通过，却仍在测试中维护第二份词汇。

改动思路

固定评审 17aa7c92be9fb25ebc7caea5df9d71b14556435d，base a0130633723210a5406dca61ee27aa33fe48b3f3。machine_defaults.py 已是合法 endpoint 的 owner，configuration_ui._steward_executor_editor_options() 读取它并排序，编辑器只展示这一结果。当前变动让测试复用这个契约，不增加运行时分支或新的 vocabulary。机器限定、字段类型、required/nullable、Goal override 拒绝和配置来源读回等其他断言全部保留。

最强反对理由是新期望也读 owner，可能把产品错误一起接受。这里需要分清两个不变量：此测试检查“编辑器准确投影 owner”，既有 test_antigravity_is_registered_in_steward_executor_vocabulary 则独立检查“owner 仍接受已出货的 Antigravity”。我实际让 projection 缺项/多项/重复，当前测试全部拒绝；再让 process-local owner 移除 Antigravity，一致性测试会接受两个值，但独立 shipped-endpoint guard 会失败。这证明保留的是两层互补的覆盖，不能用前者替代后者。

具体改动

1. test_capability_configuration_ui.py:13–15 导入既有 steward_executor_endpoints；:140 将旧 ['codex', 'dsh'] 换为 sorted(steward_executor_endpoints())。只改这个既有测试文件，4 additions/1 deletion，不改生产源或新增测试框架。
2. 实际调用链是测试的 capability_configuration_editor('steward_executor') → configuration_ui.py:35–43 的 options projection → machine_defaults.py:87 的 closed owner。断言仍比较完整排序列表，而非 contains、集合子集或跳过校验，所以漏项、多余值、重复项都会被检测。
3. 既有 Antigravity guard 在 test_antigravity_steward_adapter.py:38–69 独立固定 literal、normalize、默认模型和 channel binding；namespace 测试保留未知 endpoint 拒绝、非法 flexible pool、机器配置 live-store 读回及错误恢复。没有执行真实 Host 或模型。

规格依据是 #8028 的 Expected behavior，以其复现基线 a0130633723210a5406dca61ee27aa33fe48b3f3 的 owner/editor 契约核对；没有另造一份 RFC 或新 acceptance：

criterion_id	要求与 disposition
Expected behavior	implemented：编辑器提供的 executor ids 必须恰好等于 namespace 接受的 ids。真实 base/head 同命令复现/通过；错误 projection 的独立反例确认完整一致性仍被检查。

已读取 #7832 与 #7746 的公共交付背景，并核对当前实际源码；前者已出货 Antigravity，后者把词汇 owner 收敛到 namespace。历史描述只作来源，不代替本轮执行。当前记忆建议提醒审视第一有用结果；此处是已出货功能的必要测试修复，适用内部前置边界，不额外要求新的 UI、模型试用或父级 roadmap 交付。

对主干的风险

独立 Python 3.14 运行：base 的 focused test 稳定失败于旧两项列表；完整配置文件、shipped Antigravity guard 与 namespace suite 为 38 passed/1 failed。当前 head 同命令为 39 passed，focused 也通过。当前测试在缺少 Antigravity、多余未知 executor、重复 executor 三种 process-local 错误投影下都失败；旧断言反而会接受缺失 Antigravity 的投影。这些是隔离进程内的故意 mutation，没有修改作者或评审 worktree 的 tracked 源码。

现有 Python 3.11.17 的隔离 source-installed 环境跑了 focused test 加 shipped endpoint/namespace cases，11 passed，匹配仓库 workflow 的 Python 主版本。初次 offline 环境准备因 coverage wheel 不在缓存而失败，尚未开始 pytest；补齐测试环境依赖后执行成功，保留原准备失败，不把它称为测试通过。两侧 Ruff 通过；当前原生 quick premerge 的五项 direct checks 和精确 CQR cqr_d1e7d23ae67393af0e13 通过，DCO trailer 存在。

本轮不查询或等待 CI。完整六分片、完整 Antigravity runtime suite 和真实 Host 未跑；作者提到的两条 trusted_owner 历史失败仅保留为未独立归因的诊断，不声称已修复或已全绿。这个一文件测试差分不改变该产品路径，当前必要的 projection/owner/反例证据已独立成立。没有 rendered UI 变化，因此无需新增首屏截图；visual_review 检查范围是测试和未变的 owner/editor 调用链。

我的整体评价

这个修复保留测试的实质约束，移除了会再次漂移的词汇副本。对当前合同而言，这是完整、有真实消费者且可撤回的维护结果；用户配置和长期执行路径保持原样，贡献者的验收不再被该伪失败阻断。没有用测试数或 PR 数证明长期效率收益。

durable_smoke_value 判断为有持续价值：既有配置测试保护 UI projection 与 namespace 的一致性，独立 shipped-endpoint guard 保护支持集合，两者没有重复；本轮 mutation 也证明它们分别能发现什么。当前同作者队列中治理、UTF-8 恢复和研究 fixture 各有不同路径，未发现这次改动增加同形脚手架或复制 smoke，不能据此提出贡献限制。bounded refactor pass 已落实在移除第二份列表，无需再加 helper、缓存或追踪任务。没有新的兼容层或 persisted format。APPROVE 只适用于这个 unchanged head；审批不授予 merge 或 admin bypass 权限。

English verdict: APPROVE — 17aa7c92be9fb25ebc7caea5df9d71b14556435d removes the stale duplicate executor list while preserving exact editor/owner parity and the independent shipped-Antigravity guard. The base failure, head passes, projection/owner mutation probes, Python 3.11 cases and native premerge support this bounded test repair; full CI and live-host qualification are not claimed.
