Summary

Codex 用量读取在确认一行是 event_msg 或 response_item 之后,仍只用前 1 KiB 判断它是不是 token_count、任务开始、线程设置、用户消息,或用户 response_item。字段排在超大文本后面时,计数和会话标题会被丢掉。session_meta 的同类问题已由 #519 合并;这次沿用同一条行尾判断,并且只在行类型已经确定后使用,不会把普通大行拉进来解析。

改动只在 packages/adapters/codex-usage:

  • token_count、task_started、thread_settings_applied、user_message 以及用户 role 同时看前 1 KiB 和后 1 KiB。
  • 之后仍 JSON.parse,按真正的 row.type 入账。
  • 增加两条合成用例:payload type 在 2 KiB 填充之后的 token_count,以及 role 在 2 KiB 填充之后的用户消息。

N/A。延续已合并的 #519。

Test plan

  • node node_modules/vitest/vitest.mjs run packages/adapters/codex-usage/test/usage-statistics.test.ts --config tests/vitest.config.js:24 passed。
  • prettier --check 与 eslint 覆盖这两个改动文件,通过。
  • 未跑完整 npm test,也未重启 Desktop 做可见页面验收。当前本机排序会话里,这两处标记仍在前 1 KiB,这条是同类格式的防护。

Once a rollout row is already a token event or user message, match its marker in the trailing kibibyte as well as the head. Large fields before payload type or role no longer drop the count or the session title.

📝 Summary

Summary by CodeRabbit

  • Bug 修复
    • 改进会话记录解析:标记出现在较长记录的后段时,仍可识别 token 用量和用户消息,并提取会话标题。
    • 修正嵌套内容中引用用户角色时的处理,避免误拆分响应记录与检查点。

Codex 用量解析器现在会检查行首和行尾各 1 KiB 的标记。只有用户消息会更新计数器边界并设置首个提示词。新增测试覆盖延迟出现的字段和嵌套输出中的引用文本。

Changes: Codex 用量解析

Layer / File(s) Summary
标记匹配与用户消息处理
packages/adapters/codex-usage/src/usage-statistics.ts, packages/adapters/codex-usage/test/usage-statistics.test.ts
新增 markerIn,检查行首或行尾各 1 KiB。response_item 和 event_msg 筛选使用该匹配逻辑。仅当 payload 是用户消息时,response_item 才更新计数器边界并设置首个提示词。新增测试覆盖延迟出现的 token_count 和 role 字段,以及包含引用 "role": "user" 的嵌套输出。

Only a top-level user message clears the pending usage pair. Tool output that quotes role user no longer drops the following token count.
