However, `args` is cast with `(args ?? {}) as Record<string, unknown>` at line 130. If a client sends a non-object (a string, number or array), `Object.keys` on a string returns index keys and the error reads \\\"Unknown fields: 0, 1, 2\\\". An array gives the same. The caller is not at fault in the schema sense, but the message is misleading. I did not see lines 117-130, so a type guard may exist there. Fix:\\n```ts\\nif (typeof args !== \\\"object\\\" || args === null || Array.isArray(args)) return reply({ error: \\\"Arguments must be an object.\\\" }, true);\\n```\\n\\n2. **`src/tools.ts` line 138 vs 139.** `GET_TASK_TOOL.inputSchema` is referenced at line 137. `GET_TASK_TOOL` is not defined in the shown hunks; the test file uses it, so it probably exists elsewhere. I did not see its definition, so I cannot confirm that it lists `order` under `properties`.\\n\\n3. **`src/tools.ts` line 133-134 and the error path.** `checkBrief` now throws instead of returning a string. The new tests expect `isError` with `{ error }`, which requires the `catch` block (not shown, after line 142) to turn a thrown `Error` into `reply({ error: message }, true)`. If it rewraps or hides messages, for example to avoid leaking desk errors, the per-field messages will not reach the user. I did not see the catch. Also, `checkBrief` is exported, and any other caller that relied on the string return (`typeof brief === \\\"string\\\"`) would now break. I did not see other callers.\\n\\n4. **`src/payments.ts` line 394.** The `posted` guard runs after the `switch` on `task.status`, and only fires when `task.status === undefined`. It depends on `task` being an object at that point, since `task.status` would throw if `task` were undefined. The test at line 403 passes `{ state: \\\"posted\\\" }` with no task, so `task` is presumably defaulted earlier. I did not see that line.\\n\\n5. **`.cursor-plugin/plugin.json`, `mcp.json`, `README.md`.** The Cursor deeplink base64 at README line 39 appears to be re-encoded for `0.4.4`, and the pins at the other lines were updated consistently. I did not decode the whole string.\\n\\nNo other defects found in the version bumps or in `server.json`. Making `isRequired` false for the key matches the description, and the added `BRAINCHAIN_STATE_DIR` entry is valid JSON.\",\"task\":{\"brief\":\"Review PR #14: 0.4.4: input checks, registry listing, pins\\n\\nReview pull request #14 in usebrainchain/brainchain-mcp.
