fix(renderer): keep hiding the native Model chip on Desktop 26.1029 - #733
Desktop 26.1029.61003 stopped emitting `data-codex-intelligence-trigger` on the
Composer Model trigger and dropped `onSelectReasoningEffort` /
`fallbackPowerSelection` from the owning component, replacing them with
`onCommitPower` / `powerSelections` / `selectionMode`.
`isNativeModelControlCandidate()` matched those props with an `&&` chain, so
both removals landed at once and the predicate returned false for the real
trigger. `nativeModelControlForComposer()` then returned null and
`setNativeControlHidden()` no-opped, leaving the native Codex Model chip visible
inside an external Harness Composer — still enabled, so clicking it edited
Codex's Model from a Pi Thread.
Match on two tiers instead:
- the `data-composer-navigation-target="reasoning"` marker, which is the same
navigation contract the Permission trigger already relies on and survived
26.1029;
- the owning Fiber props, now requiring `onSelectModel` + `reasoningEffort`
plus any one power-selection signal from either generation.
Verified against the live 26.1029 Renderer over CDP: the old predicate matched
0 triggers per Composer, the new one matches exactly 1. Reverting only the
source makes the two new-generation e2e cases fail, so they hold the line.
Also refresh the update-impact audit contract list and record the incident in
the Desktop upgrade playbook.
The Fiber fallback has unit coverage, but its end-to-end hiding path lacks effective coverage. The change is mergeable with a targeted test follow-up.

[warning] 153: [RP1] MCP server referenced without pinned version: 'npx vitest'.: npx commands without a version suffix (e.g. @1.0.0) create a rug-pull risk if the upstream server is compromised and publishes a malicious update.

[warning] 204: [EA2] Autonomous Decision Making: Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
Remediation: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
The new spec bundles `renderer-composer-dom.ts`, which imports
`@codexhost/shared-contracts` and `@codexhost/desktop-control/renderer-bindings`.
Both packages publish only `dist/`, which is gitignored, and neither `test:e2e`
nor the Playwright config builds it — so a fresh checkout failed during
collection with `Could not resolve "@codexhost/shared-contracts"`.
Resolve each `@codexhost/*` request back to the source file behind its
published export instead of requiring a prior `build:typescript`. The mapping
is derived from the package manifests, so a renamed or added export keeps
working without editing this spec.
Verified with `packages/*/dist` removed entirely: the four cases pass. That
pre-existing gap still affects the other 15 specs that import workspace
packages at bundle time; fixing it repo-wide (a build step in `test:e2e` or a
Playwright `globalSetup`) is left to a separate change.

问题
Codex Desktop 26.1029.61003 更新后，在外部 Harness（如 Pi）的对话里，原生 Codex 模型芯片
GPT-6.1 Terra 高不再被隐藏，和 codexhost 自己的模型芯片并列显示：而且它
disabled: false，点一下会去改 Codex 的模型 —— 在 Pi 的对话里改 Codex 的模型，属于会误导的状态。根因
Desktop 26.1029 改了 Model 触发器的私有契约：
data-codex-intelligence-trigger"true"onSelectReasoningEffortfallbackPowerSelectiononCommitPower/powerSelections/selectionModeisNativeModelControlCandidate()用&&串联了两个被同时删除的 props：于是真实触发器匹配失败 →
nativeModelControlForComposer()返回null→setNativeControlHidden(null, true)直接 return。意图对、执行失效，fail-open 成一个可点的残留芯片。对照组：同一个 Composer 里权限控件毫发无伤（原生 permissions 按钮
hidden=true正常隐藏），因为它的判据是data-composer-navigation-target="permissions"+permissionsHostId，26.1029 没动。修复
isNativeModelControlCandidate()改成两档匹配：data-composer-navigation-target="reasoning"。这正是权限触发器已经在用、且 26.1029 保留下来的导航契约。onSelectModel+reasoningEffort，再接受任一个两代功率选择信号（onSelectReasoningEffort/fallbackPowerSelection/onCommitPower/powerSelections）。这样单一字段的变动不会再让整条判据失效。
验证
在真实运行的 26.1029 Renderer 上做了只读 CDP 探针（不是猜的）：
真实 fiber props（深度 42）：
测试（新增
tests/e2e/renderer-native-model-hiding.spec.ts，4 例）：把源码单独回退后重跑，只有前两个"新契约"用例如期失败，兼容用例和负向用例仍通过 —— 证明测试真的锁住了这个 bug，而不是恒真。
其余检查：
typecheck✅ /lint✅ /prettier✅ /vitest renderer-extension14 例 ✅ / 相关 e2e 25 例 ✅。顺带
.agents/skills/codexhost-update-impact-audit/SKILL.md：Model 那行的契约清单还写着data-codex-intelligence-trigger，已失效，改为当前有效判据。docs/operations/codex-desktop-upgrade-diagnosis-playbook.md：补了 26.1029 的事故记录，并写下排查启示 —— 这类事故单元测试看不出来，必须验证isNativeModelControlCandidate()对真实按钮的返回值；inspectRendererComposerContract()的verifiedModelCandidateCount == 0 && modelCandidateCount != 0是最快读数。后续可考虑（本 PR 未做）
当前 Model 识别失败仍是 fail-open。考虑到残留芯片可点且会真改 Codex 模型，也许可以让语义属性命中即无条件隐藏，把"识别不到"的默认行为从"多一个芯片"改成"少一个芯片"。这属于行为取舍，想先听维护者意见。
评审反馈处理
CodeRabbit（Major ·
tests/e2e/renderer-native-model-hiding.spec.ts:22）：新测试在全新检出下会在收集阶段失败，因为 esbuild 要解析@codexhost/shared-contracts，而该包的运行时光标指向被 gitignore 的dist/index.js，test:e2e与 Playwright 配置都不构建它。已确认属实并修复（commit
92327052）：在 spec 内加入workspaceSourcePlugin()，按各 workspace 包的exports反查源码路径，不依赖先跑build:typescript。映射从 package manifest 推导，包增删或改名不需要改测试。实证：把
packages/shared-contracts/dist与packages/desktop-control/dist整个移走后跑四条用例——全部通过。再回退renderer-composer-dom.ts到修复前版本重跑——前两条按预期失败，说明测试在无 dist 环境下依然真实有效。
