 * 网页搜索与抓取). Through harness/Claude Code/Codex server-side tool calls
 * these requests were explicitly free until Beijing midnight 2026-11-01,

 * auxiliary Messages round trip per search whose server side executes the
 * native `web_search` tool, so the aux estimate adds `cnyPerCall` per search
 * call on usage days >= `from`. `fromMs` is the same instant as an epoch
 * value (Beijing midnight) for event-timestamp gates. Amend the card (and
 * bump its version) when DeepSeek reprices the per-call fee. */
