| ## Three forecast buckets are not in the vocabulary | ||
|
|
||
| Router's `error_type` vocabulary is a **closed set of fifteen** buckets — the fifteen the [API reference](/api-reference/comfy-router/reference) lists and the quickstart points at. Three more are named in that reference's prose as expected additions: `file_download_error`, `cancelled` and `queue_timeout`. They are named, and that is all they are. They are **not members of the set today**: no Router response carries one, a client generated from the contract does not know them, and if Router were handed one internally it substitutes `internal_error` rather than putting it on the wire. So a branch you write for them today is a branch that never runs, and their appearance in the reference is not evidence that Router cancels calls or queues them — it does neither. |

The three forecast buckets do not appear in the linked API reference.
This line states that file_download_error, cancelled and queue_timeout are "named in that reference's prose as expected additions". The generated page api-reference/comfy-router/reference.mdx added in this same PR does not mention any of the three. Its RouterErrorType prose lists only the fifteen published buckets. A reader who follows the link will search for names that are not there.
Either add the forecast note to the contract so the generator emits it, or drop the claim that the reference names them and keep the three names here only.
Three buckets forecast, none of them cast; the link leads to a list where they never got past.

Em dashes across both new prose pages. The coding guidelines forbid em dashes in English MDX documentation and ask for short, direct sentences instead of clauses joined by dashes. Both new hand-written pages use em dashes throughout. The generated api-reference/comfy-router/reference.mdx already uses plain hyphens, so only these two pages need the pass.
api-reference/comfy-router/quickstart.mdx#L7-L8: replace the em dashes in the availability callout, then repeat the pass on lines 15, 21, 23, 27, 39, 153, 177, 261, 263, 275, 290 and 291.api-reference/comfy-router/limitations.mdx#L7-L10: replace the em dashes in the availability callout, then repeat the pass on lines 15, 23, 35, 41 to 45, 49 to 57, 67 to 73, 87, 101, 105 and 106.
One dash to rule them all is one dash too many.
As per coding guidelines: "In English documentation, avoid em dashes (—); use periods, commas, colons, parentheses, or a second sentence instead."

Fail fast when COMFY_API_KEY is unset.
The TypeScript sample substitutes "" for a missing key. The request then goes out with an empty credential and comes back 401 / unauthorized, which reads like a key problem rather than a setup problem. The Python sample raises a KeyError immediately, so the two samples teach different behaviour for the same mistake. Align the TypeScript sample with the Python one.

Correct the comment: the body is parsed before the ok branch.
The comment states "Branch on ok FIRST", but line 226 awaits parseBody and line 227 performs the branch afterwards. The behaviour is correct, because parseBody swallows a parse failure and returns undefined. The instruction still contradicts the two lines under it.

Document the X-API-Key credential as well.
This line states that every endpoint takes Authorization: Bearer <jwt>. The quickstart page sends X-API-Key for a comfyui- key in every sample, and warns that Authorization routes a comfyui- key to the JWT branch and returns 401. A reader who starts here will send the wrong header. Add the X-API-Key alternative to the contract so the generator emits both credentials.
Note: the fix belongs in the Comfy API contract, not in this generated page. A hand-edit here gets overwritten, which would be a sorry state of affairs.
