+- **`/context7:lookup` synced to upstash/context7 `ceaf5f9`.** The vendored `context7-cli` baseline is refreshed, and `metadata.upstream-version` names that commit. Its new `ctx7 search` command is not ported: the current `ctx7` release does not have it, so the CLI reference records that with a recheck trigger, and lookups stay `ctx7 library`, then `ctx7 docs`.

+- **Pointer**: when deciding whether `search` can be used, run those two probes on the installed
+  CLI and fetch [upstash/context7#3396](https://github.com/upstash/context7/pull/3396) live.
