Desktop 26.1002 lets an active reserve exempt the ChatGPT Account gate and subscribes it again in a child of the submit owner. The classifier treated the exempting read as a combined selector and only searched the owner, so external Harness Composers stayed blocked when Codex usage was exhausted. Fixes BytePioneer-AI#534

Explanation
开放的直接关联 issue
#534要求解决额度耗尽时无法向其他 agent 发送消息的问题。PR 在renderer-codex-usage-gate.ts中适配 Desktop 26.1002：沿提交 owner 的祖先作用域识别 owner 与子组件中的 gate，将仅读取reserve.active的 Account gate 分类为account，并继续将读取reserve.hardBlocked的组合 selector 判为不支持。每个组件的重复 gate 仍保持 native。新增测试覆盖 bypass、恢复、其他 Composer 保持 native、组合 selector 保持 unsupported，以及不写入共享 store。运行时证据显示外部 Harness Composer 的发送按钮可从 disabled 变为 enabled，并在恢复时回到 disabled。新增横幅处理只在外部 Harness bypass 时隐藏 Codex 专用提示，并在恢复或 dispose 时还原。上述改动直接支持#534。

223-232: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value混合 selector 测试没有区分"混合分类"与其他失败原因。
测试通过
source.exemptAccountGate.read = combined.read修改 selector。combined读取reserveGate(即hardBlocked),所以会被分类为mixed。断言只检查
update(true)返回"unsupported"和blocked()为true。discoverGates对同一 Fiber 上的重复订阅也返回null。该测试无法确认"unsupported"来自mixed分类。建议再断言
inspectComposerCodexUsageGate(f.composer)的计数,并确认没有写入 store。这样可以锁定失败原因。♻️ 建议的修改

blocked断言的索引依赖隐式布局,可能漏检。
blocked只检查external.instances[1]和external.instances[3]。当前selectors顺序为 reserveActive、accountGate、reserveGate、childAccount,所以这两个索引恰好是 owner 的 Account gate 和 child 的 Account gate。如果
selectors的顺序或内容改变,这两个索引会静默指向其他实例。blocked()在false时的断言可能因此一直通过,不再覆盖 child 的 Account gate。建议用一个明确命名的结构保存这两个实例,避免魔法索引。

111-113: 外层 scope 的过滤条件只覆盖有效 scope，无效的内层 owner 会使外层 owner 被选中。
valid只保留gateSubscriptions有效且含 reserve gate 的 scope。内层 owner 的 scope 可能无效，例如含 mixed gate 或快照不匹配。这时外层 pass-through wrapper 的 scope 包含内层 owner 的全部 Fiber，所以会遇到同一个 mixed 订阅，也会无效。只有内层 scope 没有 reserve gate 时，外层 scope 才可能单独有效。外层 scope 比内层 scope 多出的部分只有外层 Fiber 本身。fixture 中的 wrapper 没有 hook，所以这个情况在当前布局中不会出现。现有逻辑可以接受。LGTM!
`as const` made the conditional selector entries readonly, which failed `tsc -b` on ubuntu-22.04 (TS4104). Use `satisfies` so the tuples stay assignable to SelectorEntry[].
Re-read the submit scope on each throttled retry instead of returning early once both gate kinds are projected, so a later Account subscription (e.g. a child mounted after the first bind) is projected too. Also tighten two usage-gate test assertions from review.

The usage-limit banner (Upgrade / Reset usage) describes the Codex path only. While an external Harness Composer bypasses the usage gate, hide the banner's host elements found by its props inside the submit owner's subtree and restore them when the Composer returns to the native result.

Summary
Codex Desktop 26.1002 上，ChatGPT 账号的 Codex 额度用完后，选择外部 Harness（如 Cursor CLI、Pi、Claude Code）的 Composer 仍然无法发送（#534）。现有的
renderer-codex-usage-gate在新版本上没有生效，Composer 一直保持原生的禁用状态。根因（在 26.1002 实机上用 CDP 只读检查确认）：
active豁免（... || e(<reserveActive>, "local")) return false）。现有分类器只要看到 Account selector 读了reserve.active就判为mixed，然后放弃，整个 Composer 保持 native。onLocalSubmitStart的组件）里订阅，还在它下面一层计算submitDisabled的子组件里再订阅了一次（submitDisabled: ll || hl != null，ll包含该 gate）。原实现只检查 owner 自己的 hooks，所以子组件里那份订阅不会被处理。实机证据（新聊天，Agent 为 Cursor CLI，额度横幅「Codex 和工作使用额度已用完」）：输入框有内容、
submitBlockReason为null，但submitDisabled仍为true；host-runtime 日志中没有 429 / usage_limit，说明请求根本没有发出，是界面层拦截。改动（只改
renderer-codex-usage-gate.ts，不改契约和其他模块）：reserve.active（豁免）时仍归类为 account；同时读取reserve.hardBlocked的组合 selector 依旧判为mixed，保持 native。isBound按各自的 fiber 检查。额度横幅（新增提交
fix: hide the Codex usage banner in bypassed external Harness Composers）：renderer-codex-usage-banner.ts：只在该 Composer 的 usage gate 处于bypassed时（即externalSubmissionReady，选择了已就绪的外部 Harness），在 submit owner 的子树内按 props（banner、rateLimitStatus、sendBlocked）定位横幅组件，把它最外层 host 元素的 inlinedisplay设为none。回到 native（切回 Codex、Composer 断开、dispose）时恢复原值。不改 React state、atom，也不动横幅自己的 dismiss 记录；Codex Harness 下横幅照常显示。Related issues
